Description

この発明は、老朽化した下水道管、上水道管、農業用水管、ガス管などの既設管を更生する更生管の製管方法に関するものである。 The present invention relates to a method for producing a rehabilitation pipe for rehabilitating existing pipes such as an aged sewer pipe, a water pipe, an agricultural water pipe, and a gas pipe.

従来より、老朽化した既設管を更生するため、両側縁部に接合部が形成された螺旋状の帯状部材を既設管内に供給するとともに、隣接する帯状部材の接合部同士を互いに接合して更生管を製管し、更生管に新たに帯状部材を供給して更生管を付加形成することが実施されている。例えば、特許文献１，２に記載されるように、既設管内に製管機を設置するとともに、帯状部材を中空円筒状に巻き重ねた輸送用巻重体を地上に設置し、輸送用巻重体から螺旋状に引き出された帯状部材を既設管内の製管機に供給し、製管機を既設管の軸心回りに回転させて隣接する帯状部材の接合部同士を互いに接合して更生管を製管し、回転せずに製管された更生管に新たに帯状部材を供給して更生管を既設管の軸心方向に付加形成することが行われている。 Conventionally, in order to rehabilitate an aged existing pipe, a spiral belt-like member with joints formed on both side edges is supplied into the existing pipe, and the joints of adjacent belt-like members are joined together to rehabilitate. It is practiced to manufacture a tube, and supply a new strip member to the rehabilitation tube to form a rehabilitation tube. For example, as described in Patent Documents 1 and 2, a pipe making machine is installed in an existing pipe, and a transport winding body in which a belt-like member is wound in a hollow cylindrical shape is installed on the ground. The strip-shaped member drawn out in a spiral shape is supplied to a pipe-making machine in the existing pipe, and the pipe-making machine is rotated around the axis of the existing pipe to join the joint portions of the adjacent band-shaped members together to produce a regenerated pipe. A strip-shaped member is newly supplied to a rehabilitated pipe that has been piped and manufactured without rotation, and the rehabilitated pipe is additionally formed in the axial direction of the existing pipe.

ところで、前述した製管機による更生管の製管方法においては、帯状部材の輸送用巻重体を発進マンホールの地上に設置する一方、発電機を到達マンホールの地上に設置するとともに、既設管内に電動モータおよび電動モータで駆動される油圧ポンプからなる油圧ユニットを設置し、発電機と油圧ユニットの電動モータを電源ケーブルを介して接続する一方、油圧ユニットの油圧ポンプと製管機における接合機構の油圧モータとを油圧配管を介して接続している。これにより、螺旋状の帯状部材と油圧モータに圧油を供給する油圧配管とを異なるマンホールを通して供給することができるため、螺旋状の帯状部材および油圧配管が絡まることはなく、円滑に製管作業を行うことができる。 By the way, in the above-described method for producing rehabilitating pipes using a pipe making machine, while the transporting roll of the belt-like member is installed on the ground of the starting manhole, the generator is installed on the ground of the reaching manhole and the existing pipe is electrically A hydraulic unit consisting of a motor and a hydraulic pump driven by an electric motor is installed, and the generator and the electric motor of the hydraulic unit are connected via a power cable, while the hydraulic pump of the hydraulic unit and the hydraulic pressure of the joining mechanism in the pipe making machine The motor is connected via hydraulic piping. As a result, the spiral belt-like member and the hydraulic piping that supplies the hydraulic oil to the hydraulic motor can be supplied through different manholes, so that the spiral belt-like member and the hydraulic piping are not entangled and can be smoothly piped. It can be performed.

ここで、製管機は、既設管の軸心回りに回転するため、油圧ユニットからの油圧配管は、回転継手を介して油圧モータに接続されている。 Here, since the pipe making machine rotates around the axis of the existing pipe, the hydraulic pipe from the hydraulic unit is connected to the hydraulic motor via a rotary joint.

しかしながら、現場によっては、施工区間の交通事情、例えば、マンホールが交差点にあるなどの理由から、発進マンホールおよび到達マンホールの両方を開放することができない場合がある。この場合は、実際の施工区間よりも遠方の別のマンホールを開放し、そのマンホールを通して帯状部材を引き入れて製管作業を行う必要があり、通常の製管作業に比較してより多くの作業員を配置する必要があることから、コストがかさむという問題があった。 However, depending on the site, both the starting manhole and the reaching manhole may not be opened due to the traffic situation in the construction section, for example, because the manhole is at an intersection. In this case, it is necessary to open another manhole farther than the actual construction section, and draw the belt-like member through the manhole to perform pipe making work, and more workers than normal pipe making work. There is a problem that the cost is increased.

また、別案としては、事前に発進マンホールから到達マンホールまで油圧配管を敷設して、発進マンホールまで折り返した後、油圧配管を更生管の外周側に配置するように製管作業を行い、製管作業後に油圧配管を引き抜く、あるいは、埋め殺すことも提案されている。しかしながら、この方法では、油圧配管が引っかかって切断するトラブルが発生したり、油圧配管を埋め殺すため、完全なモルタル層に比較して強度低下が懸念され、顧客の理解が得にくいなどの問題がある。 Also, as an alternative, after laying hydraulic piping from the starting manhole to the reaching manhole in advance and turning back to the starting manhole, pipework is performed so that the hydraulic piping is arranged on the outer periphery side of the rehabilitation pipe, It has also been proposed to pull out or bury the hydraulic piping after work. However, with this method, problems such as the occurrence of troubles due to the hydraulic piping getting caught or being buried, and the hydraulic piping being buried, are concerned about a decrease in strength compared to the complete mortar layer, and it is difficult to obtain the customer's understanding. is there.

なお、帯状部材の輸送用巻重体とともに、発電機および油圧ユニットを発進マンホール側の地上に設置し、油圧配管を既設管内に引き込み、製管機の油圧モータに回転継手を介して接続して製管作業を行うときには、既設管の軸心回りに製管機が回転することに伴って、製管機に螺旋状に供給される帯状部材の外周に油圧配管が巻きつくことから、早晩製管不能に陥る。 A generator and a hydraulic unit are installed on the ground on the starting manhole side, along with a transport roll for the belt-shaped member, and hydraulic piping is drawn into the existing pipe and connected to the hydraulic motor of the pipe making machine via a rotary joint. When performing pipe work, as the pipe making machine rotates around the axis of the existing pipe, hydraulic piping wraps around the outer periphery of the strip-like member that is spirally supplied to the pipe making machine. It becomes impossible.

本発明は、このような問題点に鑑みてなされたもので、施工区間の両方のマンホールを開放することができない場合であっても、開放された一方のマンホールを通して製管機に帯状部材および動力を供給して更生管を円滑に製管することのできる更生管の製管方法を提供するものである。 The present invention has been made in view of such problems, and even when it is not possible to open both manholes in the construction section, the belt-like member and the power are supplied to the pipe making machine through one opened manhole. The rehabilitated pipe can be smoothly produced by supplying the regenerated pipe.

本発明は、互いに隣接する帯状部材の接合部同士を接合する接合機構を有する製管機を既設管内に設置し、両側縁部に接合部が形成された螺旋状の帯状部材を既設管内に引き入れて製管機の接合機構に供給するとともに、製管機を既設管の軸心回りに回転させて隣接する接合部同士を互いに接合して更生管を製管し、回転せずに製管された更生管に新たに帯状部材を供給して更生管を既設管の軸心方向に付加形成する更生管の製管方法であって、帯状部材を中空円筒状に巻き重ねた輸送用巻重体を一方のマンホールまたは一方のマンホール側の地上に設置するとともに、動力ユニットを一方のマンホール側の地上に設置し、動力ユニットの動力供給ラインを、輸送用巻重体の中空部および輸送用巻重体から引き出されて製管機の接合機構に供給される螺旋状の帯状部材の内方を通過させて接合機構のモータに回転継手を介して接続することを特徴とするものである。 In the present invention, a pipe making machine having a joining mechanism that joins joint portions of adjacent strip members is installed in an existing pipe, and a spiral strip member having joints formed on both side edges is drawn into the existing pipe. To the joint mechanism of the pipe making machine and rotate the pipe making machine around the axis of the existing pipe to join adjacent joints together to make a renovated pipe. A method for producing a rehabilitation pipe in which a new band member is supplied to the rehabilitation pipe and the rehabilitation pipe is additionally formed in the axial direction of the existing pipe. Installed on one manhole or ground on one manhole side, installed the power unit on the ground on one manhole side, and pulled out the power supply line of the power unit from the hollow part of the transport winding body and the transport winding body Used for the joining mechanism of It is characterized in that connected via a rotary joint to the motor of the joint mechanism is passed through the inside of the spiral strip being.

本発明によれば、接合機構を有する製管機を既設管内に設置する一方、両側縁部に接合部が形成された帯状部材を中空円筒状に巻き重ねた輸送用巻重体を一方のマンホールまたは一方のマンホール側の地上に設置するとともに、動力ユニットを一方のマンホール側の地上に設置する。そして、輸送用巻重体から帯状部材を螺旋状に引き出し、一方のマンホールから、または、一方のマンホールを経て既設管内に引き入れ、製管機の接合機構に供給する。また、動力ユニットの動力供給ラインを、輸送用巻重体の中空部および輸送用巻重体から引き出されて製管機の接合機構に供給される螺旋状の帯状部材の内方を通過させて接合機構のモータに回転継手を介して接続する。この状態で接合機構のモータを回転駆動すれば、接合機構は、帯状部材を挟み込んで送り出すとともに、相対的に帯状部材に沿ってその送り出し方向とは逆方向に周回移動する。すなわち、製管機を既設管の軸心回りに回転させて隣接する接合部同士を互いに接合して更生管を製管し、回転せずに製管された更生管に新たに帯状部材を供給して更生管を既設管の軸心方向に付加形成する。 According to the present invention, a pipe making machine having a joining mechanism is installed in an existing pipe, while a transporting wound body in which a belt-like member having joints formed on both side edges is wound into a hollow cylindrical shape is attached to one manhole or While installing on the ground of one manhole side, the power unit is installed on the ground of one manhole side. Then, the belt-like member is drawn out spirally from the winding body for transportation, drawn into the existing pipe from one manhole or through one manhole, and supplied to the joining mechanism of the pipe making machine. Further, the power supply line of the power unit is passed through the inside of the hollow portion of the transport winding body and the spiral belt-like member that is drawn out of the transport winding body and supplied to the joining mechanism of the pipe making machine. Connected to the motor via a rotary joint. If the motor of the joining mechanism is rotationally driven in this state, the joining mechanism sandwiches and feeds the belt-like member, and relatively moves around the belt-like member in the direction opposite to the feeding direction. In other words, the pipe making machine is rotated around the axis of the existing pipe, the adjacent joints are joined together to produce a renovated pipe, and a new strip member is supplied to the renovated pipe produced without rotation. Then, the rehabilitation pipe is additionally formed in the axial direction of the existing pipe.

この際、接合機構のモータに動力を供給する動力供給ラインは、帯状部材を中空円筒状に巻き重ねた輸送用巻重体の中空部を通過するとともに、輸送用巻重体から引き出されて製管機の接合機構に供給される螺旋状の帯状部材の内方を通過し、回転継手を介して接合機構のモータに接続されていることから、製管機が既設管の軸心回りに回転しても、螺旋状の帯状部材との相対的な位置関係が変化することはない。したがって、動力供給ラインが帯状部材と絡まることはなく、製管作業を円滑に行うことができる。 At this time, the power supply line for supplying power to the motor of the joining mechanism passes through the hollow portion of the transport winding body in which the belt-like member is wound in a hollow cylindrical shape, and is drawn out from the transport winding body to make a pipe making machine The pipe making machine rotates around the axis of the existing pipe because it passes through the inside of the spiral belt member supplied to the joint mechanism and is connected to the motor of the joint mechanism through a rotary joint. However, the relative positional relationship with the spiral belt-shaped member does not change. Therefore, the power supply line is not entangled with the belt-like member, and the pipe making operation can be performed smoothly.

なお、動力供給ラインは、回転継手に接続されているため、製管機の回転に連動して回転することはなく、動力供給ラインに捩れが発生することはない。 Since the power supply line is connected to the rotary joint, the power supply line does not rotate in conjunction with the rotation of the pipe making machine, and the power supply line is not twisted.

本発明は、互いに隣接する帯状部材の接合部同士を接合する接合機構を有する製管機をマンホール内に設置し、両側縁部に接合部が形成された螺旋状の帯状部材をマンホール内に引き入れて製管機の接合機構に供給するとともに、製管機を既設管の軸心回りに回転させて隣接する接合部同士を互いに接合して更生管を製管し、回転せずに製管された更生管に新たに帯状部材を供給して更生管を既設管の軸心方向に付加形成する一方、更生管を更生管の付加形成方向とは逆方向に牽引し、あるいは、製管機を押圧して既設管内に挿入する更生管の製管方法であって、帯状部材を中空円筒状に巻き重ねた輸送用巻重体および動力ユニットを、製管機を設置する一方のマンホール側の地上に設置し、動力ユニットの動力供給ラインを、輸送用巻重体の中空部および輸送用巻重体から引き出されて製管機の接合機構に供給される螺旋状の帯状部材の内方を通過させて接合機構のモータに回転継手を介して接続することを特徴とするものである。 In the present invention, a pipe making machine having a joining mechanism for joining joint portions of adjacent strip members is installed in a manhole, and a spiral strip member having joint portions formed on both side edges is drawn into the manhole. To the joint mechanism of the pipe making machine and rotate the pipe making machine around the axis of the existing pipe to join adjacent joints together to make a renovated pipe. and while adding formed in the axial direction of the existing pipe a rehabilitating pipe is newly supplied strip in rehabilitating pipe, and pulling in the opposite direction to the additional formation direction of the rehabilitating pipe further raw tube or pipe producing machine Is a method of making a rehabilitating pipe that is inserted into an existing pipe by pressing a transporting roll and a power unit in which a belt-like member is wound into a hollow cylinder, and the ground on the one manhole side where the pipe making machine is installed. The power supply line of the power unit is installed in the It is characterized in that it is connected to the motor of the joining mechanism through a rotary joint through the inside of a spiral belt-like member that is drawn out from the hollow portion and the winding body for transportation and supplied to the joining mechanism of the pipe making machine. Is.

本発明によれば、接合機構を有する製管機を一方のマンホール内に設置する一方、両側縁部に接合部が形成された帯状部材を中空円筒状に巻き重ねた輸送用巻重体および動力ユニットを、製管機を設置する一方のマンホール側の地上に設置する。そして、輸送用巻重体から帯状部材を螺旋状に引き出し、一方のマンホール内において、製管機の接合機構に供給する。また、動力ユニットの動力供給ラインを、輸送用巻重体の中空部および輸送用巻重体から引き出されて製管機の接合機構に供給される螺旋状の帯状部材の内方を通過させて接合機構のモータに回転継手を介して接続する。この状態で接合機構のモータを回転駆動すれば、接合機構は、帯状部材を挟み込んで送り出すとともに、相対的に帯状部材に沿ってその送り出し方向とは逆方向に周回移動する。すなわち、一方のマンホール内において、製管機を既設管の軸心回りに回転させて隣接する接合部同士を互いに接合して更生管を製管し、回転せずに製管された更生管に新たに帯状部材を供給して更生管を既設管の軸心方向に付加形成し、合わせて、更生管を更生管の付加形成方法とは逆方向に牽引し、あるいは、製管機を押圧して既設管内に挿入する。 According to the present invention, a transporting body and a power unit in which a pipe making machine having a joining mechanism is installed in one manhole, and a belt-like member having joints formed on both side edges is wound into a hollow cylindrical shape. Is installed on the ground on one manhole side where the pipe making machine is installed. Then, the belt-like member is drawn out spirally from the winding body for transportation, and is supplied to the joining mechanism of the pipe making machine in one manhole. Further, the power supply line of the power unit is passed through the inside of the hollow portion of the transport winding body and the spiral belt-like member that is drawn out of the transport winding body and supplied to the joining mechanism of the pipe making machine. Connected to the motor via a rotary joint. If the motor of the joining mechanism is rotationally driven in this state, the joining mechanism sandwiches and feeds the belt-like member, and relatively moves around the belt-like member in the direction opposite to the feeding direction. That is, in one manhole, the pipe making machine is rotated around the axis of the existing pipe, the adjacent joints are joined together to produce a renovated pipe, and the renovated pipe is produced without rotation. new the rehabilitating pipe by supplying a belt-like member is appended formed in the axial direction of the existing pipe, combined, tow in a direction opposite to the addition method of forming a rehabilitating pipe further raw tube, or push the pipe producing machine And insert it into the existing pipe.

本発明において、動力ユニットが発電ユニットおよび油圧ユニットからなり、接合機構のモータが油圧モータであることが好ましい。これにより、発電ユニットのエンジンを介して発電機を駆動するとともに、発電された電力で油圧ユニットの電動モータを介して油圧ポンプを駆動し、油圧ポンプから吐出された圧油を油圧配管および回転継手を介して接合機構の油圧モータに供給し、油圧モータを回転駆動させることができ、油圧による大きな回転トルクを得ることができる。 In the present invention, it is preferable that the power unit includes a power generation unit and a hydraulic unit, and the motor of the joining mechanism is a hydraulic motor. As a result, the generator is driven through the engine of the power generation unit, the hydraulic pump is driven through the electric motor of the hydraulic unit with the generated electric power, and the hydraulic oil discharged from the hydraulic pump is supplied to the hydraulic piping and the rotary joint. Thus, the hydraulic motor can be driven to rotate and the hydraulic motor of the joining mechanism can be driven to rotate, and a large rotational torque due to the hydraulic pressure can be obtained.

本発明において、動力ユニットが発電ユニットであり、接合機構のモータが電動モータであることが好ましい。これにより、エンジンを介して発電機を駆動し、発電された電力を電源ケーブルおよび回転継手を介して接合機構の電動モータに供給して電動モータを回転駆動させることができ、往復一対の油圧配管を利用して圧油を供給し、還流させる場合に比較して、取り扱いが容易となる。 In the present invention, the power unit is preferably a power generation unit, and the motor of the joining mechanism is preferably an electric motor. Thus, the generator can be driven via the engine, and the generated electric power can be supplied to the electric motor of the joining mechanism via the power cable and the rotary joint to rotate the electric motor. Compared with the case where pressure oil is supplied and refluxed using the oil, the handling becomes easier.

本発明は、互いに隣接する帯状部材の接合部同士を接合する接合機構を有する製管機を既設管内に設置し、両側縁部に接合部が形成された螺旋状の帯状部材を既設管内に引き入れて製管機の接合機構に供給するとともに、製管機を既設管の軸心回りに回転させて隣接する接合部同士を互いに接合して更生管を製管し、回転せずに製管された更生管に新たに帯状部材を供給して更生管を既設管の軸心方向に付加形成する更生管の製管方法であって、帯状部材を中空円筒状に巻き重ねた輸送用巻重体を一方のマンホールまたは一方のマンホール側の地上に設置するとともに、発電機を一方のマンホール側の地上に設置し、また、油圧ユニットを既設管内に設置し、発電機の電源ケーブルを、輸送用巻重体の中空部および輸送用巻重体から引き出されて製管機の接合機構に供給される螺旋状の帯状部材の内方を通過させて油圧ユニットに直接または変圧器を介して接続するとともに、油圧ユニットの油圧配管を接合機構の油圧モータに回転継手を介して接続することを特徴とするものである。 In the present invention, a pipe making machine having a joining mechanism that joins joint portions of adjacent strip members is installed in an existing pipe, and a spiral strip member having joints formed on both side edges is drawn into the existing pipe. To the joint mechanism of the pipe making machine and rotate the pipe making machine around the axis of the existing pipe to join adjacent joints together to make a renovated pipe. A method for producing a rehabilitation pipe in which a new band member is supplied to the rehabilitation pipe and the rehabilitation pipe is additionally formed in the axial direction of the existing pipe. Installed on the ground of one manhole or one manhole side, installed the generator on the ground of one manhole side, installed the hydraulic unit in the existing pipe, and connected the power cable of the generator to the transport roll Pulled out from the hollow part and the transport roll The inside of the spiral belt member supplied to the joint mechanism of the pipe making machine is passed through and connected to the hydraulic unit directly or via a transformer, and the hydraulic piping of the hydraulic unit is rotated to the hydraulic motor of the joint mechanism The connection is made through a joint.

本発明によれば、接合機構を有する製管機を既設管内に設置する一方、両側縁部に接合部が形成された帯状部材を中空円筒状に巻き重ねた輸送用巻重体を一方のマンホールまたは一方のマンホール側の地上に設置するとともに、発電機を一方のマンホール側の地上に設置する。また、油圧ユニットを既設管内に設置する。そして、輸送用巻重体から帯状部材を螺旋状に引き出し、一方のマンホールから、または、一方のマンホールを経て既設管内に引き入れ、製管機の接合機構に供給する。また、発電機からの電源ケーブルを、輸送用巻重体の中空部および輸送用巻重体から引き出されて製管機の接合機構に供給される螺旋状の帯状部材の内方を通過させ、油圧ユニットの電動モータに直接または変圧器を介して接続する。さらに、油圧ユニットの油圧ポンプからの油圧配管を接合機構の油圧モータに回転継手を介して接続する。この状態で接合機構の油圧モータを回転駆動すれば、接合機構は、帯状部材を挟み込んで送り出すとともに、相対的に帯状部材に沿ってその送り出し方向とは逆方向に周回移動する。すなわち、製管機を既設管の軸心回りに回転させて隣接する接合部同士を互いに接合して更生管を製管し、回転せずに製管された更生管に新たに帯状部材を供給して更生管を既設管の軸心方向に付加形成する。 According to the present invention, a pipe making machine having a joining mechanism is installed in an existing pipe, while a transporting wound body in which a belt-like member having joints formed on both side edges is wound into a hollow cylindrical shape is attached to one manhole or While installing on the ground of one manhole side, the generator is installed on the ground of one manhole side. A hydraulic unit is installed in the existing pipe. Then, the belt-like member is drawn out spirally from the winding body for transportation, drawn into the existing pipe from one manhole or through one manhole, and supplied to the joining mechanism of the pipe making machine. Further, the power cable from the generator is passed through the hollow portion of the transport winding body and the inside of the spiral belt-shaped member that is drawn out of the transport winding body and supplied to the joining mechanism of the pipe making machine. Connect directly or through a transformer to the electric motor. Furthermore, the hydraulic piping from the hydraulic pump of the hydraulic unit is connected to the hydraulic motor of the joining mechanism via a rotary joint. If the hydraulic motor of the joining mechanism is rotationally driven in this state, the joining mechanism sandwiches and sends out the belt-like member, and relatively moves around the belt-like member in the direction opposite to the feeding direction. In other words, the pipe making machine is rotated around the axis of the existing pipe, the adjacent joints are joined together to produce a renovated pipe, and a new strip member is supplied to the renovated pipe produced without rotation. Then, the rehabilitation pipe is additionally formed in the axial direction of the existing pipe.

この際、発電機からの電源ケーブルは、帯状部材を中空円筒状に巻き重ねた輸送用巻重体の中空部を通過するとともに、輸送用巻重体から引き出されて製管機の接合機構に供給される螺旋状の帯状部材の内方を通過し、油圧ユニットの油圧ポンプを駆動する電動モータへ直接または変圧器を介して接続されていることから、製管機が既設管の軸心回りに回転しても、螺旋状の帯状部材との相対的な位置関係が変化することはない。したがって、電源ケーブルが帯状部材と絡まることはなく、製管作業を円滑に行うことができる。 At this time, the power cable from the generator passes through the hollow portion of the transport winding body in which the belt-like member is wound into a hollow cylindrical shape, and is drawn out from the transport winding body and supplied to the joining mechanism of the pipe making machine. The pipe making machine rotates around the axis of the existing pipe because it is connected to the electric motor that drives the hydraulic pump of the hydraulic unit directly or via a transformer. Even so, the relative positional relationship with the spiral belt-shaped member does not change. Therefore, the power cable is not entangled with the belt-like member, and the pipe making operation can be performed smoothly.

ただし、接合機構の油圧モータおよび既設管内に設置された油圧ユニットの油圧ポンプは、油圧配管を介して接続されているため、製管機の回転に伴って油圧配管が油圧ユニットに接続された電源ケーブルに絡みつくことになる。このため、一定長さ製管作業を行った後、製管作業を中断し、油圧ユニットまたは回転継手に対する油圧配管の接続を解除して、電源ケーブルに対する油圧配管の絡みを取り除く縒り戻し作業が必要となる。 However, since the hydraulic motor of the joining mechanism and the hydraulic pump of the hydraulic unit installed in the existing pipe are connected via the hydraulic pipe, the power supply in which the hydraulic pipe is connected to the hydraulic unit as the pipe making machine rotates It will get tangled in the cable. For this reason, after a certain length of pipe making work, it is necessary to interrupt the pipe making work, release the connection of the hydraulic pipe to the hydraulic unit or rotary joint, and turn back the hydraulic pipe to the power cable. It becomes.

なお、油圧配管は、回転継手に接続されているため、製管機の回転に連動して回転することはなく、油圧配管そのものに捩れが発生することはない。 Since the hydraulic piping is connected to the rotary joint, it does not rotate in conjunction with the rotation of the pipe making machine, and the hydraulic piping itself does not twist.

本発明によれば、施工区間の両方のマンホールを開放することができない場合であっても、開放された一方のマンホールを通して製管機に帯状部材および動力を供給して更生管を円滑に製管することができる。 According to the present invention, even if it is not possible to open both manholes in the construction section, the rehabilitating pipe can be smoothly made by supplying the belt-like member and power to the pipe making machine through one opened manhole. can do.

帯状部材１００は、図１に示すように、可撓性を有する合成樹脂、例えば、硬質塩化ビニル、ポリエチレン、ポリプロピレンなどを押出成形して形成され、中空円筒状に巻き重ねられて輸送用巻重体Ｄ（図３参照）に形成されて現場に輸送される。この帯状部材１００は、帯板状の基板１０１の裏面に複数本（実施例においては３本）の断面Ｔ字状の補強リブ１０２が先端を基板１０１と平行に位置して設けられている。そして、基板１０１の一方の側縁部の裏面には接合凸部１０３が立設されている。また、基板１０１の他方の側縁部は、接合凸部１０３が設けられた基板１０１の側縁部が配置されるように、基板１０１の厚みだけ裏面側に段落ちした段落ち部１０４に形成されており、その段落ち部１０４に接合凸部１０３が嵌入し得る接合凹部１０５が設けられている。この接合凹部１０５には、基板１０１から離れるにつれて接合凹部１０５の突出側に位置するように傾斜された傾斜リブ１０６が形成されており、傾斜リブ１０６の先端が帯状部材１００の一方の側縁部を形成している。 As shown in FIG. 1, the belt-like member 100 is formed by extruding a flexible synthetic resin, for example, hard vinyl chloride, polyethylene, polypropylene, etc., and wound into a hollow cylinder to be wound for transportation. Formed in D (see FIG. 3) and transported to the site. The belt-like member 100 is provided with a plurality of (three in the embodiment) T-shaped reinforcing ribs 102 on the back surface of a belt-like substrate 101 with the tips positioned parallel to the substrate 101. A bonding projection 103 is erected on the back surface of one side edge of the substrate 101. Further, the other side edge portion of the substrate 101 is formed in a stepped portion 104 stepped down to the back side by the thickness of the substrate 101 so that the side edge portion of the substrate 101 provided with the bonding convex portion 103 is disposed. In the stepped portion 104, a joint concave portion 105 into which the joint convex portion 103 can be fitted is provided. An inclined rib 106 that is inclined so as to be positioned on the protruding side of the bonding recess 105 as it is separated from the substrate 101 is formed in the bonding recess 105, and the tip of the inclined rib 106 is one side edge of the band-shaped member 100. Is forming.

このような帯状部材１００は、基板１０１の裏面側、すなわち、補強リブ１０２などが立設された側が外周側になるように後述する製管機１に供給され、その接合過程において、図２（ａ），（ｂ）に示すように、互いに隣接する２つの帯状部材１００，１００のうち、一方の帯状部材１００の接合凸部１０３を、他方の帯状部材１００の接合凹部１０５に内側（先行する帯状部材１００の内周側）から嵌め込むことにより、これらの隣接する帯状部材１００，１００を相互に接合して所定の管径の更生管Ｓ（図３、図４参照）を製管することができる。 Such a belt-like member 100 is supplied to the pipe making machine 1 to be described later so that the back surface side of the substrate 101, that is, the side where the reinforcing ribs 102 and the like are erected is the outer peripheral side. As shown in a) and (b), of the two band-like members 100, 100 adjacent to each other, the bonding projection 103 of one band-like member 100 is inside (preceding) the bonding depression 105 of the other band-like member 100. By fitting from the inner peripheral side of the belt-like member 100, these adjacent belt-like members 100, 100 are joined to each other to produce a rehabilitated pipe S (see FIGS. 3 and 4) having a predetermined pipe diameter. Can do.

この際、後続する帯状部材１００の接合凸部１０３を設けた基板１０１の側縁部が先行する帯状部材１００の段落ち部１０４に配置されるとともに、後続する帯状部材１００の接合凸部１０３が設けられた側の補強リブ１０２が先行する帯状部材１００の傾斜リブ１０６に係止される。 At this time, the side edge portion of the substrate 101 provided with the joining convex portion 103 of the subsequent strip-shaped member 100 is arranged at the stepped portion 104 of the preceding strip-shaped member 100, and the joining convex portion 103 of the subsequent strip-shaped member 100 is formed. The reinforcing rib 102 on the provided side is locked to the inclined rib 106 of the preceding belt-like member 100.

次に、製管機１について図４および図５に基づいて説明する。 Next, the pipe making machine 1 will be described with reference to FIGS. 4 and 5.

この製管機１は、帯状部材１００を螺旋状に案内する成形フレーム２と、成形フレーム２に回転自在に設けられた複数個の案内ローラ３と、成形フレーム２に取り付けられ、隣接する螺旋状の帯状部材１００，１００を互いに接合する接合機構４とから構成されている。 The pipe making machine 1 includes a forming frame 2 that guides the belt-like member 100 in a spiral shape, a plurality of guide rollers 3 that are rotatably provided on the forming frame 2, and an adjacent spiral shape that is attached to the forming frame 2. The belt-like members 100 and 100 are joined to each other and a joining mechanism 4 that joins them together.

成形フレーム２は、図６に示すように、内方リンクフレーム２２および外方リンクフレーム２３を連結軸２４を介して回動自在に連結してなる複数個のリンク体２１からなり、これらの複数個のリンク体２１を順に連結して略環状に形成したものである。 As shown in FIG. 6, the molding frame 2 includes a plurality of link bodies 21 formed by rotatably connecting an inner link frame 22 and an outer link frame 23 via a connecting shaft 24. The individual link bodies 21 are connected in order to form a substantially annular shape.

ここで、各リンク体２１を構成する内方リンクフレーム２２および外方リンクフレーム２３は、前後に対向する一対のリンクプレート２２１，２３１と、これらの対向する一対のリンクプレート２２１，２３１の一端部間に架設された連結プレート２２２，２３２とから形成されている。そして、内方リンクフレーム２２における一対のリンクプレート２２１，２２１の各他端部に、外方リンクフレーム２３における一対のリンクプレート２３１，２３１の各他端部をそれぞれ重ね合わせ、それらを連結軸２４を介して回転自在に連結することにより、リンク体２１を形成する。 Here, the inner link frame 22 and the outer link frame 23 constituting each link body 21 are a pair of link plates 221 and 231 opposed to each other in the front-rear direction, and one end portions of the pair of link plates 221 and 231 opposed to each other. It is formed from connecting plates 222 and 232 installed between them. Then, the other end portions of the pair of link plates 231 and 231 in the outer link frame 23 are overlapped with the other end portions of the pair of link plates 221 and 221 in the inner link frame 22, respectively. The link body 21 is formed by being rotatably connected to each other.

また、隣接するリンク体２１，２１は、リンクフレーム２２，２３の連結プレート２２２，２３２およびリンクフレーム２２，２３の連結プレート２２２，２３２を適宜突き合わせ、ボルトナットを介して着脱自在に連結されている。 Adjacent link bodies 21 and 21 are detachably connected via bolts and nuts by appropriately connecting connection plates 222 and 232 of link frames 22 and 23 and connection plates 222 and 232 of link frames 22 and 23. .

ただし、成形フレーム２を直線状に形成できるように、特定の隣接する一対のリンク体２１，２１間が着脱できるならば、残りの連結プレート２２２，２３２については、溶接などによって着脱不能に固定してもかまわない。 However, if a specific pair of adjacent link bodies 21 and 21 can be attached and detached so that the forming frame 2 can be formed in a straight line, the remaining connecting plates 222 and 232 are fixed so as not to be attached and detached by welding or the like. It doesn't matter.

さらに、内方リンクフレーム２２の一対のリンクプレート２２１，２２１の各他端部には、回動規制片２６を設ける一方、外方リンクフレーム２３の一対のリンクプレート２３１，２３１の各他端部には、前述した回動規制片２６に対応する切欠部２７を連結軸２４の回転中心を中心とする設定半径上の一定範囲にわたって形成している。これにより、内方リンクフレーム２２に対する外方リンクフレーム２３の回動を、内方リンクフレーム２２の回動規制片２６と外方リンクフレーム２３の切欠部２７とが当接するまでの設定角度範囲に規制し、リンク体２１の内方リンクフレーム２２および外方リンクフレーム２３が内方あるいは外方に屈曲することを防止している。 Further, a rotation restricting piece 26 is provided at each other end of the pair of link plates 221 and 221 of the inner link frame 22, while each other end of the pair of link plates 231 and 231 of the outer link frame 23. The notch 27 corresponding to the rotation restricting piece 26 described above is formed over a certain range on a set radius with the rotation center of the connecting shaft 24 as the center. Thereby, the rotation of the outer link frame 23 relative to the inner link frame 22 is set within a set angle range until the rotation restricting piece 26 of the inner link frame 22 and the cutout portion 27 of the outer link frame 23 abut. The inner link frame 22 and the outer link frame 23 of the link body 21 are prevented from bending inward or outward.

案内ローラ３は、各リンク体２１の連結軸２４にそれぞれ回転自在に設けられている。ここで、案内ローラ３は、合成樹脂または金属よりなり、軸受２５を介して連結軸２４回りに回転自在に支持され、帯状部材１００の平坦な内面、すなわち、更生管Ｓの内周面に接触する。 The guide roller 3 is rotatably provided on the connecting shaft 24 of each link body 21. Here, the guide roller 3 is made of synthetic resin or metal, is rotatably supported around the connecting shaft 24 via a bearing 25, and contacts the flat inner surface of the strip member 100, that is, the inner peripheral surface of the rehabilitating pipe S. To do.

さらに、案内ローラ３は、既設管Ｋ内において、接合機構４によって互いに接合された隣接する帯状部材１００，１００から製管された更生管Ｓの内周面に接触して周回移動しつつ製管機１を既設管Ｋの軸心方向に移動させるために、更生管Ｓを構成する帯状部材１００に対し直角となるように配置されている。この案内ローラ３を更生管Ｓを構成する帯状部材１００に対し直角となるように配置するには、例えば、成形フレーム２の、接合機構４に隣接する一対のリンク体２１，２１同士の連結部において、一方のリンク体２１を他方のリンク体２１に対して管軸方向に移動させ、移動させた状態でそれぞれ接合機構４に固定すればよい。 Further, the guide roller 3 is in the existing pipe K, and is piped while moving around in contact with the inner peripheral surface of the rehabilitated pipe S piped from the adjacent strip members 100 and 100 joined together by the joining mechanism 4. In order to move the machine 1 in the axial direction of the existing pipe K, the machine 1 is arranged so as to be perpendicular to the belt-like member 100 constituting the rehabilitation pipe S. In order to arrange the guide roller 3 so as to be perpendicular to the belt-like member 100 constituting the rehabilitation pipe S, for example, a connecting portion between a pair of link bodies 21 and 21 adjacent to the joining mechanism 4 of the molding frame 2. The one link body 21 may be moved in the tube axis direction with respect to the other link body 21 and fixed to the joining mechanism 4 in the moved state.

なお、リンク体２１のうち、接合機構４が取り付けられるリンク体２１については、案内ローラ３に代えて後述する製管ローラ４２が設けられている他、製管機１の回転方向に対して接合機構４の後方となるリンク体２１については、帯状部材１００の供給に際して干渉しないように、接合機構４が取り付けられるリンク体２１よりも帯状部材１００の幅だけ更生管Ｓの形成方向とは反対方向に偏位されている（図７参照）。 Of the link bodies 21, the link body 21 to which the joining mechanism 4 is attached is provided with a tube-making roller 42 to be described later instead of the guide roller 3, and is joined to the rotation direction of the tube-making machine 1. About the link body 21 behind the mechanism 4, the direction opposite to the direction in which the rehabilitating pipe S is formed by the width of the belt-like member 100 rather than the link body 21 to which the joining mechanism 4 is attached so as not to interfere when the belt-like member 100 is supplied. (See FIG. 7).

接合機構４は、図８に示すように、製管ローラ４２および駆動ローラ４３が組になったピンチローラ４１と、成形フレーム２におけるリンク体２１の外方リンクフレーム２３に固定された歯車箱４４の歯車４４１，４４２，４４３を介してピンチローラ４１を回転させる油圧モータ４５とからなり、製管ローラ４２の回転軸および駆動ローラ４３の回転軸は、更生管Ｓのリード角に対して軸線方向が直交するように配置されて、油圧モータ４５の出力軸とともにそれぞれ歯車箱４４に回転自在に支持されている。そして、油圧モータ４５を回転駆動することにより、その出力軸、製管ローラ４２の回転軸および駆動ローラ４３の回転軸にそれぞれ固定されて互いに噛み合う歯車４４１，４４２，４４３を介して製管ローラ４２および駆動ローラ４３を互いに逆方向に回転させ、製管ローラ４２および駆動ローラ４３の間に帯状部材１００を挟み込んで送り出すように回転方向が設定されている。 As shown in FIG. 8, the joining mechanism 4 includes a pinch roller 41 in which a tube forming roller 42 and a drive roller 43 are combined, and a gear box 44 fixed to the outer link frame 23 of the link body 21 in the molding frame 2. The rotating shaft of the tube-forming roller 42 and the rotating shaft of the driving roller 43 are axial with respect to the lead angle of the renovated tube S. The hydraulic motor 45 rotates the pinch roller 41 via the gears 441, 442, and 443. Are arranged so as to be orthogonal to each other and are rotatably supported by the gear box 44 together with the output shaft of the hydraulic motor 45. Then, by rotating the hydraulic motor 45, the tube-forming roller 42 is fixed to the output shaft, the rotation shaft of the tube-forming roller 42, and the rotation shaft of the drive roller 43, and the gears 441, 442 and 443 are engaged with each other. The rotation direction is set so that the driving roller 43 is rotated in the opposite direction, and the belt-shaped member 100 is sandwiched between the tube-making roller 42 and the driving roller 43 and sent out.

ここで、製管ローラ４２は、帯状部材１００の幅寸法のほぼ２倍程度の長さを有して鋼などによって円筒状に形成され、先行する螺旋状の帯状部材１００と、後続する螺旋状の帯状部材１００とが接合されて互いに隣接する帯状部材１００，１００による更生管Ｓの平滑な内周面に外周面が接触して回転するように外径が設定されている。 Here, the tube-forming roller 42 has a length that is approximately twice the width of the belt-like member 100 and is formed into a cylindrical shape with steel or the like, and has a preceding spiral belt-like member 100 and a subsequent spiral shape. The outer diameter is set so that the outer peripheral surface contacts and rotates with the smooth inner peripheral surface of the rehabilitation pipe S formed by the adjacent band members 100 and 100.

また、駆動ローラ４３は、先行する螺旋状の帯状部材１００と、後続する螺旋状の帯状部材１００とが接合されて互いに隣接する帯状部材１００，１００において、各帯状部材１００の補強リブ１０２，１０２間に配置されるように、帯状部材１００の隣接する補強リブ１０２，１０２間に挿入可能な幅を有して複数個設けられており、その外周面と製管ローラ４２の外周面との間に帯状部材１００の基板１０１の厚みに相当する間隔を有するように外径が設定されている。したがって、駆動ローラ４３の外周面は、各帯状部材１００の隣接する補強リブ１０２，１０２間において、互いに接合された隣接する帯状部材１００，１００による更生管Ｓの外周面となる側の帯状部材１００の裏面に接して回転する。 Further, the driving roller 43 includes reinforcing ribs 102 and 102 of the belt-like members 100 in the belt-like members 100 and 100 that are adjacent to each other by joining the preceding spiral belt-like member 100 and the following spiral belt-like member 100. A plurality of strips having a width that can be inserted between adjacent reinforcing ribs 102, 102 of the belt-like member 100 are provided between the outer peripheral surface and the outer peripheral surface of the tube-forming roller 42. The outer diameter is set so as to have an interval corresponding to the thickness of the substrate 101 of the belt-like member 100. Therefore, the outer peripheral surface of the driving roller 43 is the belt-like member 100 on the side that becomes the outer peripheral surface of the rehabilitating pipe S by the adjacent belt-like members 100 and 100 joined to each other between the adjacent reinforcing ribs 102 and 102 of each belt-like member 100. Rotates in contact with the back side.

さらに、駆動ローラ４３の外周面には、ローレット加工が施されており、接合された隣接する帯状部材１００，１００に対して滑ることなく回転する。 Furthermore, the outer peripheral surface of the drive roller 43 is knurled, and rotates without sliding with respect to the adjacent band-shaped members 100 and 100 joined.

また、油圧モータ４５は、発電ユニットおよび油圧ユニットからなる動力ユニットＧから供給される圧油によって駆動される。すなわち、動力ユニットＧは、詳細には図示しないが、発電ユニットのエンジンを介して発電機が駆動される一方、発電機によって発生した電力によって油圧ユニットの電動モータが駆動されるとともに、電動モータを介して油圧ポンプが駆動され、発生した圧油が油圧配管Ｐ、例えば、フレキシブルホースを介して油圧モータ４５に供給されるようになっている。この場合、動力ユニットＧから延びる油圧配管Ｐは、回転継手４６（図４参照）を介して油圧モータ４５に接続されており、製管機１の周回移動（公転）に影響なく圧油を供給することができる。 The hydraulic motor 45 is driven by pressure oil supplied from a power unit G composed of a power generation unit and a hydraulic unit. That is, the power unit G is not shown in detail, but the generator is driven via the engine of the power generation unit, while the electric motor of the hydraulic unit is driven by the electric power generated by the generator, Then, the hydraulic pump is driven, and the generated pressure oil is supplied to the hydraulic motor 45 via a hydraulic pipe P, for example, a flexible hose. In this case, the hydraulic pipe P extending from the power unit G is connected to the hydraulic motor 45 via the rotary joint 46 (see FIG. 4), and supplies pressure oil without affecting the circular movement (revolution) of the pipe making machine 1. can do.

次に、このように構成された製管機１を用いて既設管Ｋを更生する施工手順について説明する。 Next, a construction procedure for rehabilitating the existing pipe K using the pipe making machine 1 configured as described above will be described.

まず、既設管Ｋには所定スパンごとにマンホールが設けられているが、この例では一方のマンホールＭ１は開放されているものの、他方のマンホールＭ２は閉鎖されており、開放された一方のマンホールＭ１を施工対象領域（更生領域）の発進マンホールとし、既設管Ｋ内に更生管Ｓを他方のマンホールＭ２に向けて製管する場合を説明する。 First, the existing pipe K is provided with a manhole for each predetermined span. In this example, one manhole M1 is opened, but the other manhole M2 is closed, and one manhole M1 is opened. Is a starting manhole in the construction target area (rehabilitation area), and the case where the rehabilitation pipe S is piped toward the other manhole M2 in the existing pipe K will be described.

施工前の準備として、更生管Ｓの製管には、図１に示した帯状部材１００を中空円筒状に巻き重ねた輸送用巻重体Ｄ（回転台付き）、製管機１、動力ユニットＧなどを用意し、輸送用巻重体Ｄ、動力ユニットＧを一方のマンホールＭ１側の地上に配置する。また、製管機１は、一方のマンホールＭ１を通して更生対象となる既設管Ｋ内に搬入して設置する。その際、製管機１は、案内ローラ３を設けた成形フレーム２、接合機構４に分解されて搬入され、その後組み立てられる。 As preparation before construction, the rehabilitation pipe S is manufactured by a transport roll D (with a turntable) in which the belt-like member 100 shown in FIG. Are prepared, and the transporting roll D and the power unit G are arranged on the ground on the side of one manhole M1. Moreover, the pipe making machine 1 is carried in and installed in the existing pipe K to be rehabilitated through one manhole M1. At that time, the pipe making machine 1 is disassembled into the forming frame 2 provided with the guide roller 3 and the joining mechanism 4, and then assembled.

なお、成形フレーム２については、隣接する一対のリンク体２１，２１の連結部の連結を外し、複数個のリンク体２１を１本の列にして搬入し、再び隣接する一対のリンク体２１，２１の連結部を連結して略環状に形成する。 In addition, about the shaping | molding flame | frame 2, the connection part of a pair of adjacent link bodies 21 and 21 is removed, a plurality of link bodies 21 are carried in one row, and a pair of adjacent link bodies 21, 21 connecting portions are connected to form a substantially annular shape.

また、製管機１については、製管する更生管Ｓの管径に合わせて、成形フレーム２の周長（リンク体２１の数）を調整しておく。 Moreover, about the pipe making machine 1, according to the pipe diameter of the renovated pipe S to manufacture, the circumference (the number of the link bodies 21) of the shaping | molding frame 2 is adjusted.

さらに、製管機１は、更生する既設管Ｋの内径および使用する帯状部材１００の幅に対応する螺旋ピッチとなるように調整しておく。 Furthermore, the pipe making machine 1 is adjusted so as to have a spiral pitch corresponding to the inner diameter of the existing pipe K to be rehabilitated and the width of the band-shaped member 100 to be used.

このような準備作業が完了すれば、地上に配置した輸送用巻重体Ｄの内周側から帯状部材１００を引き出して一方のマンホールＭ１を経て既設管Ｋ内に引き込み、製管機１における接合機構４のピンチローラ４１に挿通し、成形フレーム２に設けた案内ローラ３の外側に送り出す。 When such a preparatory work is completed, the belt-like member 100 is pulled out from the inner peripheral side of the transporting roll D placed on the ground, and drawn into the existing pipe K through one manhole M1, and the joining mechanism in the pipe making machine 1 4 is inserted into the pinch roller 41 and sent to the outside of the guide roller 3 provided on the molding frame 2.

次いで、案内ローラ３の外側に送り出された帯状部材１００を既設管Ｋの内周面との間に挟み込んだ状態で製管機１を既設管Ｋの軸心回りに回転させ、帯状部材１００を成形フレーム２の周囲に数回（１〜３回）巻き回し、開始用更生管Ｓａを製管する。この際、製管機１、すなわち、接合機構４が周回移動することにより、先行する螺旋状の帯状部材１００の接合凹部１０５に、後続する螺旋状の帯状部材１００の接合凸部１０３を内周側から嵌入するとともに、先行する螺旋状の帯状部材１００の段落ち部１０４に、後続する螺旋状の帯状部材１００の接合凸部１０３が設けられた基板１０１の側縁部を配置し、さらに、先行する螺旋状の帯状部材１００の傾斜リブ１０６に、後続する螺旋状の帯状部材１００の接合凸部１０３が設けられた側の補強リブ１０２を係止させて、隣接する螺旋状の帯状部材１００，１００を互いに接合する。 Subsequently, the pipe making machine 1 is rotated around the axis of the existing pipe K in a state where the band-shaped member 100 fed to the outside of the guide roller 3 is sandwiched between the inner peripheral surface of the existing pipe K, and the band-shaped member 100 is rotated. It winds around the molding frame 2 several times (1 to 3 times) to produce the rehabilitation pipe Sa for start. At this time, the pipe making machine 1, that is, the joining mechanism 4 circulates around, so that the joining convex portion 103 of the subsequent spiral belt-like member 100 is moved to the inner circumference of the joining concave portion 105 of the preceding spiral belt-like member 100. The side edge portion of the substrate 101 provided with the joining convex portion 103 of the subsequent spiral belt-like member 100 is disposed at the stepped portion 104 of the preceding spiral belt-like member 100 while being inserted from the side, The reinforcing rib 102 on the side where the joint convex portion 103 of the succeeding spiral band member 100 is engaged with the inclined rib 106 of the preceding spiral band member 100 so that the adjacent spiral band member 100 is adjacent. , 100 are joined together.

開始用更生管Ｓａの製管が完了したならば、動力ユニットＧからの油圧配管Ｐを輸送用巻重体Ｄの中空部を通過させるとともに、輸送用巻重体Ｄから引き出されて螺旋状に延びる帯状部材１００の内方を通過させ、既設管Ｋの更生領域中程まで引き出した後、折り返して製管機１における接合機構４の回転継手４６に接続する。 Once the start rehabilitation pipe Sa has been produced, the hydraulic pipe P from the power unit G is passed through the hollow portion of the transport winding D, and is drawn out from the transport winding D and extends in a spiral shape. After passing through the inside of the member 100 and withdrawing to the middle of the rehabilitation region of the existing pipe K, it is folded and connected to the rotary joint 46 of the joining mechanism 4 in the pipe making machine 1.

油圧配管Ｐを接続すれば、製管機１の接合機構４を駆動する。これにより、接合機構４の油圧モータ４５が回転駆動してピンチローラ４１を回転させ、製管ローラ４２および駆動ローラ４３は帯状部材１００を挟み込んで送り出すとともに、相対的に帯状部材１００に沿ってその送り出し方向とは逆方向に周回移動（公転）する。すなわち、接合機構４が駆動するとき、製管機１は更生管Ｓの軸心を中心として公転する。 If the hydraulic pipe P is connected, the joining mechanism 4 of the pipe making machine 1 is driven. As a result, the hydraulic motor 45 of the joining mechanism 4 rotates to rotate the pinch roller 41, and the tube-making roller 42 and the drive roller 43 sandwich and feed the belt-shaped member 100, and relatively move along the belt-shaped member 100. Moves (revolves) in the direction opposite to the feed direction. That is, when the joining mechanism 4 is driven, the pipe making machine 1 revolves around the axis of the renovated pipe S.

この際、ピンチローラ４１の回転によって周回移動する成形フレーム２、案内ローラ３に案内されて開始用更生管Ｓａに隣接するように相対的に送り込まれた帯状部材１００は、その接合凸部１０３を開始用更生管Ｓａの帯状部材１００の接合凹部１０５に内周側から嵌入させるとともに、開始用更生管Ｓａの帯状部材１００の段落ち部１０４に後続の帯状部材１００の後端側側縁部を配置し、さらに、開始用更生管Ｓａの帯状部材１００の傾斜リブ１０６に後続の帯状部材１００の後端側の補強リブ１０２を係止させて隣接する螺旋状の帯状部材１００，１００を互いに接合して更生管Ｓを製管する（図２（ｂ）参照）。 At this time, the belt-like member 100 guided by the forming frame 2 and the guide roller 3 that revolves around by the rotation of the pinch roller 41 and relatively fed so as to be adjacent to the starting rehabilitation pipe Sa has the joint projection 103 formed thereon. While inserting into the junction recessed part 105 of the strip | belt-shaped member 100 of the starting rehabilitation pipe Sa from an inner peripheral side, the rear end side edge part of the succeeding strip-shaped member 100 is set in the stepped part 104 of the strip-shaped member 100 of the starting retreading pipe Sa. Further, the reinforcing ribs 102 on the rear end side of the succeeding band member 100 are engaged with the inclined ribs 106 of the band member 100 of the starting rehabilitation pipe Sa, and the adjacent spiral band members 100, 100 are joined to each other. Then, the rehabilitation pipe S is manufactured (see FIG. 2B).

このように、接合機構４のピンチローラ４１は、先行する螺旋状の帯状部材１００に後続する螺旋状の帯状部材１００を接合して更生管Ｓを製管しつつ既設管Ｋの内周面に沿って周回移動することから、結局、製管機１は、帯状部材１００を更生管Ｓに製管し、その際、周方向に移動（公転）するとともに、他方のマンホールＭ２に向けて既設管Ｋ内を移動する。 In this way, the pinch roller 41 of the joining mechanism 4 joins the spiral strip member 100 following the leading spiral strip member 100 to produce the rehabilitated tube S while forming the regenerated tube S on the inner peripheral surface of the existing tube K. As a result, the pipe making machine 1 pipes the belt-like member 100 into the rehabilitated pipe S. At that time, the pipe making machine 1 moves (revolves) in the circumferential direction and at the same time the existing pipe toward the other manhole M2. Move in K.

すなわち、製管機１に供給された帯状部材１００は、接合機構４のピンチローラ４１によって隣接する帯状部材１００，１００が互いに接合されて更生管Ｓに製管されるとともに、製管された更生管Ｓは回転することなく既設管Ｋに配置され、その更生管Ｓの他方のマンホールＭ２側に新たに螺旋状の帯状部材１００が供給されて更生管Ｓが他方のマンホールＭ２に向けて既設管Ｋの軸心方向に付加形成される。 That is, the belt-like member 100 supplied to the pipe making machine 1 is joined to the belt-like member 100, 100 adjacent to each other by the pinch roller 41 of the joining mechanism 4 to be piped into the rehabilitating pipe S, and the rehabilitated pipe. The pipe S is arranged in the existing pipe K without rotating, and the spiral band member 100 is newly supplied to the other manhole M2 side of the rehabilitated pipe S so that the rehabilitated pipe S faces the other manhole M2. It is additionally formed in the axial direction of K.

この際、油圧配管Ｐは、帯状部材１００を中空円筒状に巻き重ねた輸送用巻重体Ｄの中空部および輸送用巻重体Ｄから引き出されて製管機１の接合機構４に供給される螺旋状の帯状部材１００の内方を通過し、接合機構４の回転継手４６に接続されている。したがって、油圧配管Ｐは、製管機１が既設管Ｋの軸心回りに回転しても、螺旋状の帯状部材１００との相対的な位置関係は変化しないことから、帯状部材１００と絡まることはなく、製管作業を円滑に行うことができる。 At this time, the hydraulic pipe P is pulled out from the hollow portion of the transport winding body D in which the belt-like member 100 is wound into a hollow cylinder and the transport winding body D, and is supplied to the joining mechanism 4 of the pipe making machine 1. It passes through the inside of the belt-shaped member 100 and is connected to the rotary joint 46 of the joining mechanism 4. Therefore, even if the pipe making machine 1 rotates around the axis of the existing pipe K, the relative position of the hydraulic pipe P with the spiral band member 100 does not change, and therefore the hydraulic pipe P becomes entangled with the band member 100. No, the pipe making work can be performed smoothly.

なお、油圧配管Ｐは、回転継手４６に接続されているため、製管機１の回転に連動して回転することはなく、油圧配管Ｐに捩れが発生することはない。 Since the hydraulic pipe P is connected to the rotary joint 46, the hydraulic pipe P does not rotate in conjunction with the rotation of the pipe making machine 1, and the hydraulic pipe P is not twisted.

既設管Ｋの施工対象領域（更生領域）の全長にわたって更生管Ｓの製管が終了すれば、更生管Ｓの管端部の帯状部材１００を切断し、次いで、製管機１を分解し、製管機１を撤去する。 When the pipe production of the rehabilitation pipe S is completed over the entire length of the construction target area (rehabilitation area) of the existing pipe K, the strip-like member 100 at the end of the rehabilitation pipe S is cut, and then the pipe making machine 1 is disassembled, The pipe making machine 1 is removed.

すなわち、成形フレーム２が複数のリンク体２１を相互に連結して形成されたものであるから、隣接する一対のリンク体２１，２１の連結部の連結を外すことで、成形フレーム２をリンク体２１の１本の列とすることができる。 That is, since the forming frame 2 is formed by connecting a plurality of link bodies 21 to each other, the forming frame 2 is connected to the link body by removing the connection of the connecting portions of the pair of adjacent link bodies 21 and 21. It can be one row of 21.

ここで、製管機１の接合機構４としては、駆動ローラ４３を備えずに、製管ローラ４２と、成形フレーム２に設けられて帯状部材１００を送り出す押込ローラ（図示せず）とを備えるものであってもよく、その場合には、外径方向に突出する部位がないため、更生管Ｓを既設管Ｋとの間にほとんど隙間を発生させることなく製管することができる。 Here, the joining mechanism 4 of the pipe making machine 1 does not include the driving roller 43 but includes the pipe forming roller 42 and a pressing roller (not shown) that is provided on the forming frame 2 and feeds the belt-shaped member 100. In this case, since there is no portion projecting in the outer diameter direction, the renovated pipe S can be produced with almost no gap between the existing pipe K.

なお、前述した実施形態においては、開放された一方のマンホールＭ１を発進マンホールとし、閉鎖された他方のマンホールＭ２を到達マンホールとして、更生管Ｓを一方のマンホールＭ１から他方のマンホールＭ２にかけて製管する場合を説明したが、開放された一方のマンホールＭ１を到達マンホールとし、閉鎖された他方のマンホールＭ２を発進マンホールとして、更生管Ｓを他方のマンホールＭ２から一方のマンホールＭ１にかけて製管することもできる。 In the above-described embodiment, the remanufactured pipe S is formed from one manhole M1 to the other manhole M2 with one opened manhole M1 as a starting manhole and the other closed manhole M2 as a reaching manhole. Although the case has been described, it is also possible to make the rehabilitation pipe S from the other manhole M2 to the one manhole M1 with the one manhole M1 opened as the reaching manhole, the other manhole M2 closed as the starting manhole. .

すなわち、図９に示すように、開放された一方のマンホールＭ１を到達マンホールとし、一方のマンホールＭ１側の地上に帯状部材１００の輸送用巻重体Ｄおよび動力ユニットＧを設置し、動力ユニットＧからの油圧配管Ｐを、帯状部材１００の輸送用巻重体Ｄの中空部および輸送用巻重体Ｄから引き出されて製管機１の接合機構４に供給された螺旋状の帯状部材１００の内方を通過させて、既設管Ｋ内に配置された製管機１の接合機構４の油圧モータ４５に回転継手４６を介して接続するようにしてもよい。 That is, as shown in FIG. 9, one opened manhole M1 is used as a reaching manhole, and the transport roll D and the power unit G of the belt-like member 100 are installed on the ground on the one manhole M1 side. The inside of the spiral belt-shaped member 100 drawn out from the hollow portion of the transport winding body D of the belt-shaped member 100 and the transport winding body D and supplied to the joining mechanism 4 of the pipe making machine 1. You may make it pass through and connect with the hydraulic motor 45 of the joining mechanism 4 of the pipe making machine 1 arrange | positioned in the existing pipe K through the rotary joint 46. FIG.

このような製管方法を採用すれば、一定長さの更生管Ｓが製管されて既設管Ｋが更生されたならば、全体の施工区間の更生が完了することを待つことなく一方のマンホールＭ１を通して既設管Ｋ内に支保工などの機材を搬入することができるため、更生管Ｓが製管された部分から支保工の設置を開始することができる。したがって、全体の施工区間の更生が完了した後、既設管Ｋの内周面と更生管Ｓの外周面との空間に裏込め材を充填するこれまでの製管方法に比較して、製管作業と裏込め材の充填作業を並行して実施することができることから、工期を大幅に短縮することができる利点がある。 If such a pipe making method is adopted, if the rehabilitated pipe S of a certain length is produced and the existing pipe K is rehabilitated, one manhole is not waited for completion of rehabilitation of the entire construction section. Since equipment such as a support work can be carried into the existing pipe K through M1, the installation of the support work can be started from the portion where the rehabilitation pipe S is manufactured. Therefore, after the renovation of the entire construction section is completed, compared with the conventional pipe making method in which the space between the inner peripheral surface of the existing pipe K and the outer peripheral surface of the renovated pipe S is filled with the backfill material, Since the work and the filling work of the backfill material can be performed in parallel, there is an advantage that the construction period can be greatly shortened.

また、発電ユニットおよび油圧ユニットからなる動力ユニットＧを一方のマンホールＭ１側の地上に設置するとともに、接合機構４の油圧モータ４５に油圧配管Ｐを利用して圧油を供給する場合を説明したが、接合機構４のモータとして電動モータを採用できる場合は、動力ユニットＧとして発電ユニットのみを一方のマンホールＭ１側の地上に設置し、発生した電力を電源ケーブルおよび回転継手を介して電動モータに供給するようにしてもよい。 In addition, a case has been described in which a power unit G including a power generation unit and a hydraulic unit is installed on the ground on one manhole M1 side, and pressure oil is supplied to the hydraulic motor 45 of the joining mechanism 4 using the hydraulic piping P. When an electric motor can be adopted as the motor of the joining mechanism 4, only the power generation unit is installed as the power unit G on the ground on one manhole M1 side, and the generated electric power is supplied to the electric motor via the power cable and the rotary joint. You may make it do.

この場合の電源ケーブルも、帯状部材１００の輸送用巻重体Ｄの中空部および輸送用巻重体Ｄから引き出されて製管機１の接合機構４に供給された螺旋状の帯状部材１００の内方を通過させて、既設管Ｋ内に配置された製管機の接合機構４の電動モータに回転継手を介して接続する必要がある。 The power cable in this case is also the inner side of the spiral belt-shaped member 100 drawn out from the hollow portion of the transport winding D of the belt-shaped member 100 and the transport mechanism D and supplied to the joining mechanism 4 of the pipe making machine 1. It is necessary to connect to the electric motor of the joining mechanism 4 of the pipe making machine arranged in the existing pipe K through a rotary joint.

さらに、大口径の更生管Ｓを長距離にわたって製管する場合において、電動モータを採用できない環境下においては、図１０に示すように、動力ユニットＧのうち、発電ユニットＧ１を一方のマンホールＭ１側の地上に設置するとともに、油圧ユニットＧ２を製管機１近傍の既設管Ｋ内に設置し、発電ユニットＧ１からの電源ケーブルＣを輸送用巻重体Ｄの中空部および輸送用巻重体Ｄから螺旋状に引き出された帯状部材１００の内方を通過させて、変圧器Ｔまたは直接油圧ユニットＧ２の電動モータに接続し、油圧ユニットＧ２の油圧ポンプからの油圧配管Ｐを接合機構４の油圧モータ４５に回転継手を介して供給するようにしてもよい。 Further, in the case where the large-diameter rehabilitating pipe S is manufactured over a long distance, in an environment where an electric motor cannot be employed, as shown in FIG. 10, the power generation unit G1 is connected to one manhole M1 side as shown in FIG. The hydraulic unit G2 is installed in the existing pipe K in the vicinity of the pipe making machine 1, and the power cable C from the power generation unit G1 is spiraled from the hollow portion of the transport winding D and the transport winding D. Is passed through the inside of the strip-shaped member 100 drawn out like a pipe and connected to the electric motor of the transformer T or the hydraulic unit G2 directly, and the hydraulic pipe P from the hydraulic pump of the hydraulic unit G2 is connected to the hydraulic motor 45 of the joining mechanism 4 You may make it supply to a rotary joint.

この場合も、発電ユニットＧ１からの電源ケーブルＣは、帯状部材１００の輸送用巻重体Ｄの中空部を通過するとともに、輸送用巻重体１００から螺旋状に引き出された帯状部材１００の内方を通過し、油圧ユニットＧ２の電動モータへ直接または変圧器Ｔを介して接続されていることから、製管機１が既設管Ｋの軸心回りに回転しても、電源ケーブルＣが帯状部材１００と絡まることはなく、製管作業を円滑に行うことができる。また、発電ユニットＧ１からの電源ケーブルＣを変圧器Ｔに接続して油圧ユニットＧ２に必要な電圧に変電すると、予め電圧降下を見込んで小径の電源ケーブルＣで高電圧を送ることができることから、電源ケーブルＣの取り扱いが容易となる。 Also in this case, the power cable C from the power generation unit G1 passes through the hollow portion of the transport winding D of the strip member 100, and passes through the inside of the strip member 100 drawn out spirally from the transport spool 100. Since it passes through and is connected to the electric motor of the hydraulic unit G2 directly or via the transformer T, even if the pipe making machine 1 rotates around the axis of the existing pipe K, the power cable C remains in the strip member 100. The pipe making operation can be performed smoothly. In addition, if the power cable C from the power generation unit G1 is connected to the transformer T and transformed into the voltage required for the hydraulic unit G2, it is possible to send a high voltage with the small diameter power cable C in anticipation of a voltage drop in advance. The power cable C can be easily handled.

ただし、既設管Ｋ内に設置された油圧ユニットＧ２の油圧ポンプから接合機構４の油圧モータ４５に油圧配管Ｐが接続されているため、製管機１の回転に伴って油圧配管Ｐが油圧ユニットＧ２に接続された電源ケーブルＣに絡みつくことになる。このため、一定長さ製管作業を行った後、製管作業を中断し、油圧ユニットＧ２または回転継手４６に対する油圧配管Ｐの接続を解除し、電源ケーブルＣに対する油圧配管Ｐの絡みを取り除く縒り戻し作業を行う必要がある。 However, since the hydraulic pipe P is connected from the hydraulic pump of the hydraulic unit G2 installed in the existing pipe K to the hydraulic motor 45 of the joining mechanism 4, the hydraulic pipe P is connected to the hydraulic unit as the pipe making machine 1 rotates. The power cable C connected to G2 is entangled. For this reason, after performing the pipe making work for a certain length, the pipe making work is interrupted, the connection of the hydraulic pipe P to the hydraulic unit G2 or the rotary joint 46 is released, and the entanglement of the hydraulic pipe P to the power cable C is removed. It is necessary to perform return work.

さらにまた、帯状部材１００の輸送用巻重体Ｄを一方のマンホールＭ１側の地上に設置する場合を説明したが、マンホールの大きさによっては、帯状部材１００の輸送用巻重体Ｄを一方のマンホールＭ１内に設置しても構わない。 Furthermore, although the case where the transporting roll D of the belt-like member 100 is installed on the ground on the one manhole M1 side has been described, depending on the size of the manhole, the transporting roll D of the belt-like member 100 may be placed on the one manhole M1. It may be installed inside.

また、帯状部材１００を中空円筒状に巻き重ねた輸送用巻重体Ｄの内周側から帯状部材１００を引き出して既設管Ｋ内の製管機１に螺旋状に供給する場合を説明したが、輸送用巻重体Ｄの外周側から帯状部材１００を螺旋状に引き出して製管機１に供給することもできる。具体的には、輸送用巻重体Ｄの中空部の中心を水平な回転軸として輸送用巻重体Ｄを回転自在に支持し、帯状部材１００を緩めながら水平な回転軸方向に沿って外方に引き出すことにより螺旋状の帯状部材１００を供給することができる。 Moreover, although the case where the belt-shaped member 100 is pulled out from the inner peripheral side of the transporting wound body D in which the belt-shaped member 100 is wound in a hollow cylindrical shape and supplied to the pipe making machine 1 in the existing pipe K has been described, The belt-like member 100 can be drawn out spirally from the outer peripheral side of the transport roll D and supplied to the pipe making machine 1. Specifically, the transport winding D is rotatably supported by using the center of the hollow portion of the transport winding D as a horizontal rotation axis, and outwards along the horizontal rotation axis direction while loosening the belt-like member 100. By pulling out, the spiral strip member 100 can be supplied.

ところで、前述した実施形態においては、既設管Ｋに製管機１を設置し、製管機１を既設管Ｋの軸心回りに回転させて更生管Ｓを製管し、回転せずに製管された更生管Ｓに新たに帯状部材１００を供給して更生管Ｓを付加形成する製管方法について説明したが、製管機１を開放された一方のマンホールＭ１に設置し、製管機１を既設管Ｋの軸心回りに回転させて更生管Ｓを製管し、回転せずに製管された更生管Ｓに新たに帯状部材１００を供給して更生管Ｓを付加形成する一方、製管された更生管Ｓを更生管Ｓの付加形成方向とは逆方向に牽引して、あるいは、製管機１を押圧して既設管Ｋ内に搬入し、既設管Ｋを更生することもできる。 By the way, in embodiment mentioned above, the pipe making machine 1 is installed in the existing pipe K, the pipe making machine 1 is rotated around the axis center of the existing pipe K, the renovated pipe S is piped, and it manufactures without rotating. Although the pipe manufacturing method which supplies the strip | belt-shaped member 100 to the renovated pipe S newly piped and adds and forms the renovated pipe S was demonstrated, the pipe making machine 1 was installed in one manhole M1 opened, and the pipe making machine While 1 is rotated around the axis of the existing pipe K, the rehabilitation pipe S is formed, and the belt-like member 100 is newly supplied to the rehabilitation pipe S that is formed without rotation, and the rehabilitation pipe S is additionally formed. Pulling the renovated pipe S that has been piped in the direction opposite to the direction in which the regenerated pipe S is added, or pressing the pipe making machine 1 and carrying it into the existing pipe K to rehabilitate the existing pipe K You can also.

以下、製管機１を開放された一方のマンホールＭ１に設置して既設管Ｋを更生する施工手順について図１１に基づいて説明する。 Hereinafter, the construction procedure for installing the pipe making machine 1 in the opened one manhole M1 and rehabilitating the existing pipe K will be described with reference to FIG.

この製管機１も、前述した実施形態と同一の構造、すなわち、供給された帯状部材１００を螺旋状に案内する成形フレーム２と、成形フレーム２に回転自在に設けられた複数個の案内ローラ３と、成形フレーム２に取り付けられ、隣接する螺旋状の帯状部材１００，１００を互いに接合する接合機構４とから構成されるものであり、同一部材には同一符号を付して詳細な説明を省略する。 This pipe making machine 1 also has the same structure as that of the above-described embodiment, that is, a forming frame 2 that guides the supplied strip member 100 in a spiral manner, and a plurality of guide rollers that are rotatably provided on the forming frame 2. 3 and a joining mechanism 4 which is attached to the molding frame 2 and joins the adjacent spiral belt-like members 100, 100 to each other. Omitted.

開放された一方のマンホールＭ１側の地上に帯状部材１００が巻き重ねられた輸送用巻重体Ｄ（回転台付き）を設置するとともに、発電機および油圧ユニットからなる動力ユニットＧを設置する。また、製管機１を一方のマンホールＭ１内にクレーンなどを利用して搬入し、組み立てておく。 A transporting roll D (with a turntable) on which a belt-like member 100 is wound is installed on the ground on the side of one opened manhole M1, and a power unit G including a generator and a hydraulic unit is installed. Further, the pipe making machine 1 is carried into one manhole M1 using a crane or the like and assembled.

一方、閉鎖された他方のマンホールＭ２には、更生管Ｓを既設管Ｋ内に牽引するためのウインチＷを設置し、ウインチドラムに巻き取られたワイヤやロープなどの索条体ｗを図示しない通線材を利用して一方のマンホールＭ１側に導いておく。 On the other hand, a winch W for pulling the rehabilitation pipe S into the existing pipe K is installed in the other manhole M2 that is closed, and the strips w such as wires and ropes wound around the winch drum are not shown. Lead to one manhole M1 side using a wire.

準備作業が終了すれば、輸送用巻重体Ｄを軸心回りに回転させながら帯状部材１００をその内周側から引き出して一方のマンホールＭ１内に引き入れ、その先端を製管機１の接合機構４に導入する。 When the preparatory work is completed, the belt-like member 100 is pulled out from the inner peripheral side while rotating the transporting roll D around the axis, and is drawn into one manhole M1, and the leading end is joined to the joining mechanism 4 of the pipe making machine 1. To introduce.

そして、一方のマンホールＭ１内において、製管機１をクレーンなどを利用して吊り上げた状態で、接合機構４を正回転させて帯状部材１００を送り出し、約２周ほど巻き回した後、帯状部材１００を絞り込んで案内ローラ３に抱きつかせ、成形フレーム２の外周に対応する内径、すなわち、既設管Ｋの内径よりも若干小径に形成する。次いで、帯状部材１００をさらに４〜７周ほど製管機１の成形フレーム２の回りに巻き回して、既設管Ｋの内径よりも僅かに小径の短い開始用更生管Ｓａを製管する。この後、一方のマンホールＭ１に引き込まれた索条体ｗの先端を開始用更生管Ｓａの先頭部に連結する。 Then, in one manhole M1, in a state where the pipe making machine 1 is lifted using a crane or the like, the joining mechanism 4 is rotated forward to feed the belt-shaped member 100, and after winding about two rounds, the belt-shaped member 100 is squeezed and held by the guide roller 3, so that the inner diameter corresponding to the outer periphery of the forming frame 2, that is, the inner diameter of the existing pipe K is slightly smaller. Next, the belt-like member 100 is further wound around the forming frame 2 of the pipe making machine 1 for about 4 to 7 rounds, and the start rehabilitation pipe Sa having a slightly smaller diameter than the inner diameter of the existing pipe K is produced. Thereafter, the leading end of the striatum w drawn into one manhole M1 is connected to the leading portion of the start rehabilitation pipe Sa.

次いで、動力ユニットＧからの油圧配管Ｐを輸送用巻重体Ｄの中空部を通過させるとともに、輸送用巻重体Ｄから引き出されて螺旋状に延びる帯状部材１００の内方を通過させ、製管機１における接合機構４の回転継手４６に接続するとともに、開始用更生管Ｓａの先端部を一方のマンホールＭ１内の既設管口に吊り下ろした後、製管機１の接合機構４を駆動する。すなわち、一方のマンホールＭ１内で製管機１の接合機構４を正回転させる。これにより、製管機１の接合機構４は、既設管Ｋに支持された開始用更生管Ｓａに対して帯状部材１００の相対的な送り出し方向となる逆方向に既設管Ｋの軸心回りに回転（公転）し、更生管Ｓを製管する。この場合、製管機１が更生管Ｓを製管する（進行しようとする）方向は、更生対象の既設管Ｋとは反対方向となる。 Next, the hydraulic pipe P from the power unit G is passed through the hollow portion of the transport winding D, and the inside of the strip-shaped member 100 that is drawn out of the transport winding D and extends in a spiral shape is passed through the pipe making machine. 1 is connected to the rotary joint 46 of the joining mechanism 4, and the tip of the start rehabilitation pipe Sa is suspended from the existing pipe opening in one manhole M1, and then the joining mechanism 4 of the pipe making machine 1 is driven. That is, the joining mechanism 4 of the pipe making machine 1 is rotated forward in one manhole M1. Thereby, the joining mechanism 4 of the pipe making machine 1 is arranged around the axis of the existing pipe K in the opposite direction to the relative feeding direction of the strip member 100 with respect to the start rehabilitation pipe Sa supported by the existing pipe K. Rotate (revolve) to produce rehabilitation pipe S. In this case, the direction in which the pipe making machine 1 pipes the rehabilitated pipe S (is going to proceed) is the opposite direction to the existing pipe K to be rehabilitated.

この製管作業と同時進行にてウインチＷを駆動させ、更生管Ｓの軸心方向への製管速度とほぼ同じ速さで、索条体ｗにより更生管Ｓを既設管Ｋ内に牽引する。これにより、製管機１が更生管Ｓを取り外さない状態で、かつ、一方のマンホールＭ１内の定位置から移動しないまま、製管された更生管Ｓが巻き回されることなく既設管Ｋ内に挿入される。 The winch W is driven simultaneously with this pipe making work, and the rehabilitated pipe S is pulled into the existing pipe K by the ridge body w at the same speed as the pipe making speed in the axial direction of the rehabilitated pipe S. . As a result, in the state where the pipe making machine 1 does not remove the rehabilitated pipe S and does not move from a fixed position in one manhole M1, the regenerated pipe S that has been piped is not wound around the existing pipe K. Inserted into.

そして、更生管Ｓを製管して既設管Ｋ内に挿入し、他方のマンホールＭ２内に達したならば、帯状部材１００を製管機１の前段側で切断し、その端部処理を行って製管機１を更生管Ｓから取り外すとともに、索条体ｗを更生管Ｓから取り外した後、製管機１を分解し、撤去するものである。 And if the rehabilitation pipe S is piped and inserted into the existing pipe K and reaches the other manhole M2, the strip member 100 is cut at the front side of the pipe making machine 1 and the end treatment is performed. The pipe making machine 1 is removed from the rehabilitated pipe S, and after the striated body w is removed from the rehabilitated pipe S, the pipe making machine 1 is disassembled and removed.

この実施形態においても、油圧配管Ｐは、帯状部材１００を中空円筒状に巻き重ねた輸送用巻重体Ｄの中空部および輸送用巻重体Ｄから引き出されて製管機１の接合機構４に供給される螺旋状の帯状部材１００の内方を通過し、接合機構４の回転継手４６に接続されている。したがって、油圧配管Ｐは、製管機１が既設管Ｋの軸心回りに回転しても、螺旋状の帯状部材１００との相対的な位置関係は変化しないことから、帯状部材１００と絡まることはなく、製管作業を円滑に行うことができる。 Also in this embodiment, the hydraulic pipe P is drawn out from the hollow portion of the transport winding body D in which the belt-like member 100 is wound into a hollow cylinder and the transport winding body D, and supplied to the joining mechanism 4 of the pipe making machine 1. It passes through the inside of the spiral belt member 100 to be connected to the rotary joint 46 of the joining mechanism 4. Therefore, even if the pipe making machine 1 rotates around the axis of the existing pipe K, the relative position of the hydraulic pipe P with the spiral band member 100 does not change, and therefore the hydraulic pipe P becomes entangled with the band member 100. No, the pipe making work can be performed smoothly.

なお、前述した実施形態においては、図１に示した帯状部材１００によって更生管Ｓを製管する場合を説明したが、このような帯状部材１００に限定されるものではない。 In addition, in embodiment mentioned above, although the case where the renovated pipe | tube S was manufactured with the strip | belt-shaped member 100 shown in FIG. 1 was demonstrated, it is not limited to such a strip | belt-shaped member 100.

例えば、図１２に示すように、帯状体１１０と、隣接する帯状体１１０，１１０を接合するコネクタ１２０とからなる帯状部材１００Ａであってもよい。 For example, as shown in FIG. 12, a belt-like member 100 </ b> A including a belt-like body 110 and a connector 120 that joins the adjacent belt-like bodies 110 and 110 may be used.

帯状体１１０は、可撓性を有する合成樹脂を押出成形して形成され、帯板状の基板１１１の裏面に複数本の断面Ｔ字状の補強リブ１１２が先端を基板１１１と平行に位置して設けられている。そして、基板１１１の両側縁部には、それぞれ接合凹溝１１３が長手方向に沿って連続的に形成されている。 The band-shaped body 110 is formed by extruding a flexible synthetic resin, and a plurality of T-shaped reinforcing ribs 112 are located on the back surface of the band-plate-shaped substrate 111 so that the ends thereof are parallel to the substrate 111. Is provided. And the joint ditch | groove 113 is continuously formed in the both-sides edge part of the board | substrate 111 along a longitudinal direction, respectively.

一方、コネクタ１２０は、隣接する帯状体１１０，１１０が突き合わされた両側縁部の接合凹部１１３，１１３に接合可能な一対の接合凸部１２１が長手方向に沿って連続的に形成されている。 On the other hand, the connector 120 is formed with a pair of joint convex portions 121 that can be joined to the joint concave portions 113 and 113 at both side edges where the adjacent strips 110 and 110 are abutted, along the longitudinal direction.

これにより、互いに隣接する帯状体１１０，１１０の前端縁部と後端縁部が突き合わされた状態で、先行する帯状体１１０の後縁側接合凹部１１３および後続する帯状体１１０の前縁側接合凹部１１３に跨がってコネクタ１２０を帯状体１１０の内周側から嵌め込んで接合することにより、互いに隣接する帯状体１１０，１１０をコネクタ１２０を介して接続してなる帯状部材１００Ａを形成することができる。 Thus, the leading edge side joining recess 113 of the preceding strip 110 and the leading edge joining recess 113 of the following strip 110 in a state where the front edge and the trailing edge of the strips 110, 110 adjacent to each other are abutted. By connecting and joining the connector 120 from the inner peripheral side of the belt-like body 110 across the belt, the belt-like member 100A formed by connecting the belt-like bodies 110, 110 adjacent to each other via the connector 120 can be formed. it can.
