Description

本発明は、配管ルート上に設置された排水枡の補修方法及びそれに用いられる補修枡に関する。   The present invention relates to a method for repairing a drainage basin installed on a piping route and a repair basin used therefor.

例えば製鉄所では、熱間圧延工程において鋼板を冷却する等の目的で大量の水を使用する。この場合に海水が利用されることもあり、設備５１で使用された水は、図６に示すように、地中に埋設された配管ルートを経て海に排水される。   For example, in steelworks, a large amount of water is used for the purpose of cooling the steel sheet in the hot rolling process. In this case, seawater may be used, and the water used in the facility 51 is drained into the sea through a piping route buried in the ground as shown in FIG.

このような配管ルート上には、泥等を溜めて水だけが配管２を流れるようにするための排水枡１が適宜な間隔で設置される。   On such a piping route, drainage tubs 1 for storing mud and the like so that only water flows through the piping 2 are installed at appropriate intervals.

特開２００２−１０６０５１号公報JP 2002-106051 A

経年劣化や荷重等により排水枡１に亀裂や損傷が生じた場合、その部位をグラウトで埋める等の補修が必要となる。この場合に、例えば設備５１を休止し、排水枡１に水がなくなった状態にしてから補修する手法が考えられる。しかしながら、２４時間稼動している製鉄所等では、設備５１の休止は避ける必要がある。   When the drainage basin 1 is cracked or damaged due to aging or load, it is necessary to repair such as filling the part with grout. In this case, for example, a method may be considered in which the equipment 51 is stopped and repaired after the drainage tub 1 has no water. However, it is necessary to avoid the stoppage of the equipment 51 in a steelworks that operates for 24 hours.

また、補修を行う排水枡１を迂回するバイパスルート５２を設置するとともに（図６の点線を参照）、該排水枡１への水の流入を遮断して、排水枡１に水がなくなった状態にしてから補修する手法が考えられる。しかしながら、排水枡１の補修のためだけにバイパスルート５２を設置しなければならず、大規模な工事が必要で、工期が長くなるとともにコストがかかってしまう。   In addition, a bypass route 52 that bypasses the drainage basin 1 to be repaired is installed (see the dotted line in FIG. 6), and the inflow of water to the drainage basin 1 is blocked, and the drainage basin 1 has no water. A method to repair after that is considered. However, it is necessary to install the bypass route 52 only for repairing the drainage basin 1, which requires a large-scale construction, which increases the construction period and costs.

以上のような現状から、水が流れている状態で排水枡を補修することができる手法が望まれている。水が流れている状態で排水枡を補修する手法として、例えば排水枡１のまわりを掘削し、排水枡１の外部から補修を行うことも実施されているが、掘削作業が必要となり、大規模な工事が必要で、工期が長くなるとともにコストがかかってしまう。   From the current situation as described above, a technique capable of repairing a drainage basin in a state where water is flowing is desired. For example, excavating around the drainage basin 1 and repairing it from the outside of the drainage basin 1 has been implemented as a method of repairing the drainage basin with water flowing. Construction is necessary, and the construction period becomes longer and costs increase.

この種の技術として、例えば特許文献１には、既設のマンホール内に枡体を挿入し、枡体を上流管及び下流管でマンホールの流入口及び流出口にそれぞれ接続するようにした既設マンホールの補修方法および補修枡が開示されている。   As this type of technology, for example, Patent Document 1 discloses an existing manhole in which an enclosure is inserted into an existing manhole, and the enclosure is connected to an inlet and an outlet of the manhole by an upstream pipe and a downstream pipe, respectively. A repair method and a repair rod are disclosed.

しかしながら、特許文献１は、その底部に僅かに水が流れているようなマンホールを対象としたものである。図６に示したような配管ルートでは、大量の水が流れ、排水枡１内の水面が配管２より上方に位置するような状況となっており、特許文献１に開示された技術を適用することは難しい。   However, Patent Document 1 is directed to a manhole in which water slightly flows at the bottom. In the piping route as shown in FIG. 6, a large amount of water flows, and the water surface in the drainage basin 1 is located above the piping 2, and the technique disclosed in Patent Document 1 is applied. It ’s difficult.

本発明は以上のような状況に鑑みてなされたものであり、工期が短く、低コストで、水が流れている状態で排水枡を補修できるようにすることを目的とする。   This invention is made | formed in view of the above situations, and it aims at enabling it to repair a drainage basin in the state with a short construction period, low cost, and the water flowing.

また、本発明の補修枡の他の特徴とするところは、前記開口は、前記枡体に形成されており、前記隔離手段は、前記開口のまわりに配設された止水チューブにより構成され、前記止水チューブを膨らませて前記配管の開口のまわりに圧着させる構成となっている。この場合に、前記止水チューブが、気体を供給して膨らませた後に、その気体を抜くとともにグラウトを充填できる構成としてもよい。
また、本発明の補修枡の他の特徴とするところは、前記隔離手段は、前記配管に挿入可能とされた前記開口を構成する管部と、前記管部の外周面に設けられ、前記配管の内周面に圧着可能なシール部材とにより構成される。この場合に、前記管部が軸方向に可動であるようにしてもよい。 The drainage basin repair method of the present invention is a drainage basin repairing method for repairing a drainage basin with which pipes communicate, wherein a repair basin provided with an opening is installed in the drainage basin, Communicating with the opening of the repair rod, isolating the space around the communication site from the inside of the pipe and the repair rod, sucking up water from the isolated space in the drainage rod, and then grouting into the space It is characterized by filling.

以下、添付図面を参照して、本発明の好適な実施形態について説明する。
（第1の実施形態）
図１〜図３を参照して、第１の実施形態に係る排水枡の補修方法及びそれに用いられる補修枡を説明する。図１は、排水枡１及び補修枡１００を概略的に示す斜視図である。排水枡１は地中に埋設されており、上部開口部分が地表に露出している。排水枡１の対向する内側面には、それぞれ配管２が連通する。 Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.
(First embodiment)
With reference to FIGS. 1-3, the repair method of the drain according to 1st Embodiment and the repair rod used for it are demonstrated. FIG. 1 is a perspective view schematically showing a drainage dredge 1 and a repair rod 100. The drainage basin 1 is buried in the ground, and the upper opening is exposed on the ground surface. The pipes 2 communicate with the inner surfaces of the drainage tub 1 facing each other.

補修枡１００は、排水枡１より一回り小さな枡体１０１により構成される。枡体１０１は鋼板等の金属板からなり、配管２に対向する各側面には、配管開口２ａと略同径の開口１０２が形成されている。   The repair rod 100 is composed of a frame 101 that is slightly smaller than the drainage rod 1. The casing 101 is made of a metal plate such as a steel plate, and an opening 102 having substantially the same diameter as the pipe opening 2 a is formed on each side surface facing the pipe 2.

ここで、図１では図示を省略しているが、図２に示すように、枡体１０１の外側面には、開口１０２のまわりに環状の内壁１０３及び環状の外壁１０４が立設されている。そして、これら内壁１０３及び外壁１０４の間に、図３に示すようなゴム製の環状の止水チューブ１０５が設けられる。止水チューブ１０５は、エア用のノズル１０５ａ及びグラウト用のノズル１０５ｂを具備しており、エアにより膨らませた後に、そのエアを抜くとともにグラウトを充填できる構成となっている。   Here, although not shown in FIG. 1, as shown in FIG. 2, an annular inner wall 103 and an annular outer wall 104 are erected around the opening 102 on the outer surface of the housing 101. . Between these inner wall 103 and outer wall 104, a rubber annular water stop tube 105 as shown in FIG. 3 is provided. The water stop tube 105 includes an air nozzle 105a and a grout nozzle 105b, and after being inflated with air, the air can be removed and filled with grout.

以下、図２（ａ）〜（ｃ）を参照して、補修枡１００を用いた排水枡１の補修の手順を説明する。図２（ａ）に示すように、配管２及び排水枡１に水が流れている状態で、補修枡１００を排水枡１内に設置する。ここでは、大量の水が流れ、排水枡１内の水面が配管２より上方に位置していることを想定しているが、開口１０２から補修枡１００内に水が入り込めば、後は簡単に補修枡１００を設置することができる。なお、補修枡１００は、その上部開口面が排水枡１内の水面より上方に位置する高さを有する。   Hereinafter, with reference to FIGS. 2A to 2C, a procedure for repairing the drainage tub 1 using the repair tub 100 will be described. As shown in FIG. 2A, the repair rod 100 is installed in the drainage basin 1 with water flowing through the pipe 2 and the drainage basin 1. Here, it is assumed that a large amount of water flows and the water surface in the drainage basin 1 is located above the pipe 2. However, if water enters the repairing basin 100 from the opening 102, the rest is easy. The repair rod 100 can be installed in The repair rod 100 has a height at which the upper opening surface is located above the water surface in the drainage rod 1.

次に、配管開口２ａと補修枡１００の開口１０２との位置を合わせた状態で、止水チューブ１０５にノズル１０５ａを介してエアを供給し、止水チューブ１０５を膨らませる。これにより、図２（ｂ）に示すように、止水チューブ１０５が排水枡１の内側面の開口２ａのまわりに圧着し、配管開口２と開口１０２とが連通する。同時に、排水枡１と補修枡１００との間の空間であって、連通部位である止水チューブ１０５の周囲の空間Ｓが、配管２及び補修枡１００の内部から隔離される。   Next, in a state where the positions of the pipe opening 2 a and the opening 102 of the repair rod 100 are aligned, air is supplied to the water stop tube 105 through the nozzle 105 a to inflate the water stop tube 105. Thereby, as shown in FIG. 2B, the water stop tube 105 is crimped around the opening 2 a on the inner surface of the drainage tub 1, and the pipe opening 2 and the opening 102 communicate with each other. At the same time, the space S between the drainage dredger 1 and the repair rod 100 and around the water stop tube 105 that is a communication part is isolated from the pipe 2 and the inside of the repair rod 100.

次に、この排水枡１内の隔離された空間Ｓから水を吸い上げ、その後、図２（ｃ）に示すように、該空間Ｓに、セメントペーストやモルタル等のグラウト１０６を充填する。   Next, water is sucked up from the isolated space S in the drain 1 and then, as shown in FIG. 2C, the space S is filled with grout 106 such as cement paste or mortar.

さらに、空間Ｓのグラウト１０６が硬化した後、止水チューブ１０５からノズル１０５ａを介してエアを抜くとともに、止水チューブ１０５にノズル１０５ｂを介してグラウトを充填する。   Further, after the grout 106 in the space S is cured, air is extracted from the water stop tube 105 through the nozzle 105a, and the water stop tube 105 is filled with the grout through the nozzle 105b.

以上の手順により、排水枡１の補修が完了する。すなわち、以後は補修枡１００が排水枡として機能することになる。   The repair of the drainage basin 1 is completed by the above procedure. That is, after that, the repair rod 100 functions as a drainage rod.

以上述べたように、水が流れている状態の排水枡１に補修枡１００を設置するようにしたので、設備５１を休止したり、バイパスルート５２を設置したりする必要がなく、また、排水枡１のまわりを掘削する必要がなく、工期が短く、低コストで排水枡１を補修することができる。さらに詳細に述べれば、配管開口２ａと補修枡１００の開口１０２との位置の合わせにはダイバーによる水中作業が必要となるが、それ以外は外部の作業だけで済む。特に熱間圧延工程において鋼板を冷却した冷却水を排水する配管ルートでは、排水の温度が数十度程度に達していることもあり、水中作業が短く済む利点は大きい。   As described above, since the repair rod 100 is installed in the drainage rod 1 in a state where water is flowing, there is no need to suspend the equipment 51 or install the bypass route 52. There is no need to excavate around the dredging 1, the construction period is short, and the drainage dredging 1 can be repaired at low cost. More specifically, in order to align the positions of the pipe opening 2a and the opening 102 of the repair rod 100, an underwater operation by a diver is required, but otherwise only an external operation is required. In particular, in the piping route for draining the cooling water that has cooled the steel plate in the hot rolling process, the temperature of the drainage may reach several tens of degrees.

（第２の実施形態）
図４、５を参照して、第２の実施形態に係る排水枡の補修方法及びそれに用いられる補修枡を説明する。図４は、排水枡１及び補修枡２００を概略的に示す斜視図である。排水枡１は地中に埋設されており、上部開口部分が地表に露出している。排水枡１の対向する内側面には、それぞれ配管２が連通する。 (Second Embodiment)
With reference to FIGS. 4 and 5, a drainage gutter repair method according to the second embodiment and a repair gutter used therein will be described. FIG. 4 is a perspective view schematically showing the drainage tub 1 and the repair tub 200. The drainage basin 1 is buried in the ground, and the upper opening is exposed on the ground surface. The pipes 2 communicate with the inner surfaces of the drainage tub 1 facing each other.

補修枡２００は、排水枡１より一回り小さな枡体２０１、及び、枡体２０１に内装される可動部材２０３により構成される。枡体２０１は鋼板等の金属板からなり、配管２に対向する一方の側面に挿通穴２０２が、他方の側面に管部２０８が一体形成されている。管部２０８は、配管２内に挿入できる寸法関係を有する。なお、図４の手前側（図５の左側）を一方、図４の奥側（図５の右側）を他方と称する。   The repair rod 200 is composed of a housing 201 that is slightly smaller than the drainage rod 1 and a movable member 203 that is housed in the housing 201. The casing 201 is made of a metal plate such as a steel plate, and an insertion hole 202 is integrally formed on one side surface facing the pipe 2 and a pipe portion 208 is integrally formed on the other side surface. The pipe part 208 has a dimensional relationship that can be inserted into the pipe 2. In addition, the near side (left side of FIG. 5) of FIG. 4 is called one side, and the back side (right side of FIG. 5) of FIG. 4 is called the other side.

可動部材２０３は、枡体２０１の一方の内側面に対向する基材２０３ａと、基材２０３ａに突設された管部２０３ｂとを備える。管部２０３ｂは、補修枡２００の挿通穴２０２から突出し、配管２内に挿入できる寸法関係を有する。なお、本実施形態では、管部２０３ｂ、２０８の開口が本発明でいう開口に相当するものである。   The movable member 203 includes a base material 203a that faces one inner surface of the housing 201, and a pipe portion 203b that protrudes from the base material 203a. The pipe portion 203 b protrudes from the insertion hole 202 of the repair rod 200 and has a dimensional relationship that can be inserted into the pipe 2. In the present embodiment, the openings of the tube portions 203b and 208 correspond to the openings in the present invention.

ここで、図４では図示を省略しているが、図５に示すように、枡体２０１の一方の内側面には、挿通穴２０２のまわりに複数本の送りねじ２０４が立設されている。送りねじ２０４は、可動部材２０３の基材２０３ａを貫通した状態でナット２０５が螺合する。したがって、ナット２０５を回転させることにより、可動部材２０３を送りねじ２０４に沿って排水枡２の一方の内側面に近接させたり、離間させたりすることができる。すなわち、管部２０３ｂが軸方向に可動となっている。   Here, although not shown in FIG. 4, as shown in FIG. 5, a plurality of feed screws 204 are erected around the insertion hole 202 on one inner surface of the housing 201. . The feed screw 204 is screwed into the nut 205 while passing through the base member 203a of the movable member 203. Therefore, by rotating the nut 205, the movable member 203 can be brought close to or separated from one inner surface of the drainage tub 2 along the feed screw 204. That is, the pipe part 203b is movable in the axial direction.

さらに、枡体２０１の一方の内側面には、挿通穴２０２のまわりに可動部材２０３の基材２０３ａに対向する環状のシール部材２０６が設けられている。また、可動部材２０３の管部２０３ｂの先端外周面には、環状のシール部材２０７が設けられている。   Further, on one inner side surface of the housing 201, an annular seal member 206 is provided around the insertion hole 202 so as to face the base material 203 a of the movable member 203. An annular seal member 207 is provided on the outer peripheral surface of the distal end of the tube portion 203 b of the movable member 203.

また、管部２０８の先端外周面にも、環状のシール部材２０９が設けられている。   An annular seal member 209 is also provided on the outer peripheral surface of the distal end of the pipe portion 208.

以下、図５（ａ）〜（ｃ）を参照して、補修枡２００を用いた排水枡１の補修の手順を説明する。図５（ａ）に示すように、配管２及び排水枡１に水が流れている状態で、補修枡２００を排水枡１内に設置する。第１の実施形態と同様、大量の水が流れ、排水枡１内の水面が配管２より上方に位置していることを想定しているが、管部２０３ｂ、２０８から補修枡２００内に水が入り込めば、後は簡単に補修枡２００を設置することができる。なお、補修枡２００は、その上部開口面が排水枡１内の水面より上方に位置する高さを有する。   Hereinafter, with reference to FIGS. 5A to 5C, a procedure for repairing the drainage basin 1 using the repair basin 200 will be described. As shown in FIG. 5A, the repair rod 200 is installed in the drainage basin 1 with water flowing through the pipe 2 and the drainage basin 1. As in the first embodiment, it is assumed that a large amount of water flows and the water surface in the drainage basin 1 is located above the pipe 2, but water from the pipe portions 203 b and 208 into the repair basin 200. If it enters, repair rod 200 can be easily installed afterwards. The repair rod 200 has a height at which the upper opening surface is located above the water surface in the drainage rod 1.

次に、図５（ｂ）に示すように、ナット２０５を締め付けて可動部材２０３を一方の方向に移動させると、基材２０３ａがシール部材２０６に圧着するとともに、管部２０３ｂの先端が一方の配管２内に挿入し、シール部材２０７が配管２の内周面に圧着して、配管開口２と管部２０３ｂとが連通する。   Next, as shown in FIG. 5B, when the nut 205 is tightened and the movable member 203 is moved in one direction, the base material 203a is crimped to the seal member 206, and the tip of the tube portion 203b is moved to one side. Inserted into the pipe 2, the seal member 207 is crimped to the inner peripheral surface of the pipe 2, and the pipe opening 2 and the pipe portion 203 b communicate with each other.

さらにナット２０５を締め付けると、可動部材２０３がそれ以上進めないので、こんどは枡体２０１自体が他方の方向に移動して、管部２０８の先端が他方の配管２内に挿入し、シール部材２０９が配管２の内周面に圧着して、配管開口２と管部２０８とが連通する。   When the nut 205 is further tightened, the movable member 203 cannot advance any further, so that the casing 201 itself moves in the other direction, and the tip of the pipe portion 208 is inserted into the other pipe 2, so that the seal member 209 is moved. Is pressure-bonded to the inner peripheral surface of the pipe 2 so that the pipe opening 2 and the pipe portion 208 communicate with each other.

この状態では、排水枡１と補修枡２００との間の空間であって、連通部位である管部２０３ｂ、２０８の周囲の空間Ｓが、配管２及び補修枡２００の内部から隔離される。   In this state, a space S between the drainage tub 1 and the repair rod 200 and around the pipe portions 203b and 208, which are communication parts, is isolated from the pipe 2 and the inside of the repair rod 200.

次に、この排水枡１内の隔離された空間Ｓから水を吸い上げ、その後、図５（ｃ）に示すように、該空間Ｓに、セメントペーストやモルタル等のグラウト２１０を充填する。   Next, water is sucked up from the isolated space S in the drain 1 and then, as shown in FIG. 5C, the space S is filled with grout 210 such as cement paste or mortar.

以上の手順により、排水枡１の補修が完了する。すなわち、以後は補修枡２００が排水枡として機能することになる。   The repair of the drainage basin 1 is completed by the above procedure. That is, after that, the repair rod 200 functions as a drainage rod.

以上、本発明を実施する場合の好適な実施の形態を説明したが、本発明はこの実施の形態にのみ限定されるものではなく、本発明の趣旨を実現する範囲内で適宜変更可能である。例えば、上記実施形態では矩形状の排水枡１を説明し、枡体１０１、２０１も矩形状としたが、例えば円柱状の排水枡の場合、補修枡の枡体も排水枡より一回り小さな円柱状とすることにより本発明を適用することができる。   As mentioned above, although preferred embodiment in the case of implementing this invention was described, this invention is not limited only to this embodiment, In the range which implement | achieves the meaning of this invention, it can change suitably. . For example, in the above embodiment, the rectangular drainage basin 1 is described, and the casings 101 and 201 are also rectangular. However, for example, in the case of a cylindrical drainage basin, the repair caddy is a circle slightly smaller than the drainage basin. The present invention can be applied by making it columnar.
