(作用)
支保工装置の設置
地下に埋設された管渠において、当該管渠内に方形断面のライニング管の設置がなされる。
そして、該管渠内でのライニング管の設置施工の終了後、裏込め材(セメントミルク)注入の行われる前に、本支保工装置のライニング管内での設置作業が実施される。
支保工装置のフレーム体を分割状態で、また収縮状態の高さ調整支柱をライニング管内に搬入し、フレーム体を最小状態で組み立てる。すなわち、各分割パネルの相互の端面は対接し、かつ伸長機構はこの状態を保持する。この状態から各分割パネル間の伸長機構を均等に作動させ、フレーム体をライニング管の内面に密接させる。
次いで、高さ調整支柱をフレーム体内の所定の位置に配し、その柱部を伸長させ、その下端をフレーム体の底面部に取外し可能に固定し、その上端の受座をフレーム体の天井部に取外し可能に固定し、該高さ調整支柱の上端及び下端をフレーム体の高さ方向に固定する。これにより、ライニング管はフレーム体により方形状に保持される。この状態の支保工装置をライニング管内に所定間隔をもって設置する。

なお、セメントミルクによる浮力は反力部材によりライニング管の浮上りは阻止される。
ライニング管の内部空間
本支保工装置のフレーム体は、板状体を主体とする断面が方形状の箱型体よりなるとともにライニング管の内壁に沿って配され、また該フレーム体を剛的に保持する高さ調整支柱は細身をもってライニング管の高さ方向に配されるものであるので、その占有する空間は極めて小さく、十分な作業空間を与え、また施工中のライニング管内を流れる流水の流水抵抗が小さい。

DESCRIPTION OF EMBODIMENTS Embodiments of a support device for a pipe lining pipe and a support construction method according to the present invention will be described with reference to the drawings.
FIG. 1 to FIG. 13 show a lining pipe supporting apparatus and associated means having a square cross section (including a square and a rectangle) according to one embodiment. That is, FIGS. 1 to 3 show an overall schematic configuration of the support device S, FIGS. 4 to 12 show the structure of each part of the support device S, and FIG. 13 is used together with the support device S. Attached means (reaction force member).
In these drawings, P indicates a sewer pipe, and in this embodiment, a concrete square cross-section pipe structure is adopted. R indicates a lining pipe installed in the sewer pipe rod P. In the present embodiment, R is made of synthetic resin (usually made of vinyl chloride). In the present invention, the material of the lining pipe is not limited, but it is essential to show some elasticity.
Further, in the figure, the x-axis, y-axis, and z-axis correspond to the lateral width, height, and length (depth) of the tube rod P.

ライニング管Rは、方形断面状の管渠P内において該管渠Pの内面形状に沿って連続的に形成される。そのような形成方法の一例として、合成樹脂製の帯状部材に塑性変形部材を組み込んだ塑性変形性帯状部材を螺旋状に捲回接合して管状体を成形する過程で、角部において直角に折り曲げて方形状となす自走式製管機が採用される。
図15は本実施形態のライニング管Rに適用される帯状部材の一例を示す。
帯状部材100は本体が一定厚さの平板状をなし、その外面の長手方向に適宜数(図例では5、通常は3)の突条102が連続的に縦設される。突条102の先端部にはフランジ102aが形成される。突条102の相互間は溝104もしくは溝空間を形成する。内面106は実質的に平滑に形成される。
帯状部材100の両側には互いに内外に重合して係合する接合部100A,100Bが形成される。すなわち、前縁側接合部100Aはその前端部の突条102Aの基部が膨径され、その内面側より凹溝110が縦設され、更にこの突条102Aより張出し部112が連設される。後縁側接合部100Bは後端部の突条102Bより張出し部114が張設され、該張出し部114の端部寄りに前記前縁側接合部100Aの凹溝110に係合する凸条116が縦設される。
この帯状部材100において、中間の突条102間に金属製(通常は鋼製)の断面W字形をなす塑性変形機能材としての塑性変形材120が装着される。該塑性変形材120は図例の位置に限定されず、その他の位置あるいは複数箇所であってもよく、また、形状としてV字形、U字形等が採択される。
接合時において、相隣れる帯状部材100の前縁部と後縁部とが重なり合い、前縁側接合部100Aに後縁側接合部100Bが製管機の接合ローラ部の外面ローラと内面ローラとの挟着作用を受けて、凹溝110内に凸条116が、また、突条102Bのフランジ102a内に張出し部112の端部がそれぞれ嵌り込み、接合される。118は当接部分のシール材であり、接合性を高める。
The lining pipe R is continuously formed along the inner surface shape of the pipe rod P in the pipe rod P having a square cross section. As an example of such a forming method, in the process of forming a tubular body by spirally joining a plastic deformable band member in which a plastic deformable member is incorporated into a band member made of synthetic resin and forming a tubular body, it is bent at a right angle at the corner. A self-propelled pipe-making machine with a rectangular shape is adopted.
FIG. 15 shows an example of a belt-like member applied to the lining pipe R of this embodiment.
The band-shaped member 100 has a flat plate shape with a constant thickness, and an appropriate number (5 in the illustrated example, usually 3) of protrusions 102 are continuously provided vertically in the longitudinal direction of the outer surface. A flange 102 a is formed at the tip of the ridge 102. A groove 104 or a groove space is formed between the protrusions 102. The inner surface 106 is formed to be substantially smooth.
On both sides of the belt-like member 100, joint portions 100A and 100B are formed that are overlapped with each other inside and outside. That is, in the front edge side joint portion 100A, the base portion of the protrusion 102A at the front end is expanded, the concave groove 110 is provided vertically from the inner surface side, and the overhang portion 112 is further provided continuously from the protrusion 102A. The rear edge side joint portion 100B is provided with an overhang portion 114 extending from the protrusion 102B at the rear end portion, and a protrusion 116 that engages with the groove 110 of the front edge side joint portion 100A is vertically disposed near the end portion of the overhang portion 114. Established.
In the belt-like member 100, a plastic deformation material 120 as a plastic deformation functional material having a W-shaped cross section made of metal (usually steel) is mounted between intermediate protrusions 102. The plastic deformable material 120 is not limited to the position shown in the figure, and may be at other positions or at a plurality of locations, and a V shape, a U shape, or the like is adopted as the shape.
At the time of joining, the front edge part and the rear edge part of the adjacent belt-like members 100 overlap each other, and the rear edge side joint part 100B is sandwiched between the outer surface roller and the inner surface roller of the joining roller part of the pipe making machine. In response to the attaching action, the protrusion 116 is fitted into the groove 110, and the end of the protruding portion 112 is fitted into the flange 102a of the protrusion 102B, and joined. Reference numeral 118 denotes a seal material at the contact portion, which improves the bondability.

この支保工装置Sは、図1〜図3に示すように、ライニング管Rの内面に沿って配され、分割体(分割パネル)の組立てをもって閉合状をなすフレーム体1と、該閉合状のフレーム体1の天井部とフレーム体1の下底部とに介装され、横幅(x軸方向)方向に対称を保って配される高さ調整支柱2と、からなる。更には、本支保工装置Sによる管渠内のライニング施工において反力部材3が別途配される。これら(フレーム体1、支柱2、反力部材3)は所定の強度を採る限りにおいて素材は問わないが、通常は金属(鋼、アルミ等)製を採り、合成樹脂も除外されない。   As shown in FIG. 1 to FIG. 3, the support device S is arranged along the inner surface of the lining pipe R, and the frame body 1 that forms a closed shape by assembling the divided bodies (divided panels), and the closed shape It comprises a height adjustment column 2 that is interposed between the ceiling of the frame body 1 and the bottom bottom of the frame body 1 and is arranged symmetrically in the lateral width (x-axis direction) direction. Furthermore, the reaction force member 3 is separately arranged in the lining construction in the pipe rod by the support apparatus S. These (frame body 1, support column 2, reaction force member 3) may be made of any material as long as they have a predetermined strength, but are usually made of metal (steel, aluminum, etc.), and synthetic resin is not excluded.

以下、各部材の細部構造を説明する。
フレーム体1(図1〜図8参照)
フレーム体1は、剛性を有し、一定奥行き長さ(z軸方向)を有する複数(本実施形態では6)の分割パネル5が、ジャッキ部6及び摺動・固定部7からなる「伸長機構」を介して、それらの組立てをもって形成され、当該ライニング管Rの内面に沿って配されて閉合状の方形体をなす。すなわち、分割パネル5の相互はその対峙部をジャッキ部6及び摺動・固定部7を介して接続されて全体的に方形状の枠箱体をなす。
もっと詳しくは、このフレーム体1を構成する分割パネル5は、該ライニング管Rの下底部に配される平板状の1つの下面分割パネル5Aと、該下部分割パネル5Aの幅方向(x軸)の両端に取り付けられライニング管Rの下底部と側部とに配される曲板状の2つの下部分割パネル5Bと、該下部分割パネル5Bの両方の上端に取り付けられ、ライニング管Rの側部及び天井部に配される2つの上部分割パネル5Cと、該上部分割パネル5Cの両端に介装され、該ライニング管Rの天井部に配される上面分割パネル5Dと、からなる。そして、これらの分割パネル5A,5B,5C,5Dの相互はジャッキ部6及び摺動・固定部7からなる「伸長機構」により接続される。
Hereinafter, the detailed structure of each member will be described.

The frame body 1 has rigidity, and a plurality of (six in this embodiment) divided panels 5 having a certain depth length (z-axis direction) include a jack portion 6 and a sliding / fixing portion 7. Are formed by assembling them, and are arranged along the inner surface of the lining pipe R to form a closed rectangular body. That is, the divided panels 5 are connected to each other through the jack portion 6 and the sliding / fixing portion 7 to form a rectangular frame box as a whole.
More specifically, the dividing panel 5 constituting the frame body 1 includes a flat plate-like lower surface dividing panel 5A disposed on the lower bottom portion of the lining pipe R, and the width direction (x axis) of the lower dividing panel 5A. Two lower divided panels 5B which are attached to both ends of the lining pipe R and are arranged on the bottom and side portions of the lining pipe R, and attached to the upper ends of both of the lower divided panels 5B. And two upper divided panels 5C disposed on the ceiling portion, and an upper divided panel 5D disposed on both ends of the upper divided panel 5C and disposed on the ceiling portion of the lining pipe R. The divided panels 5A, 5B, 5C, and 5D are connected to each other by an “extension mechanism” including a jack portion 6 and a sliding / fixing portion 7.

(分割パネル5の一般的構成)(図4参照)
分割パネル5は、四角形状の可及的薄い平板10を主体とし、その四周の縁部にフランジ11が内面に向けて突設され、更にはリブ12が所定関係(等間隔、不等間隔を含む。)をもって縦方向及び横方向に立設される。フランジ11、リブ12により分割パネル5の補剛性は高められ、フランジ11、リブ12により区画される平板10には適宜に窓部13が開設され、分割パネル5の軽量化が図られる。窓部13は本実施形態では適宜に設けられるが、必須部分を除いて全てのフランジ11、リブ12により区画される平板10に設けてもよい。
(General structure of the division | segmentation panel 5) (refer FIG. 4)
The divided panel 5 is mainly composed of a rectangular flat plate 10 as much as possible. A flange 11 protrudes from an edge of the four circumferences toward the inner surface, and ribs 12 have a predetermined relationship (equal intervals, unequal intervals). In the vertical direction and the horizontal direction. The supplemental rigidity of the divided panel 5 is enhanced by the flange 11 and the rib 12, and a window portion 13 is appropriately opened in the flat plate 10 partitioned by the flange 11 and the rib 12, thereby reducing the weight of the divided panel 5. The window portion 13 is appropriately provided in the present embodiment, but may be provided on the flat plate 10 partitioned by all the flanges 11 and ribs 12 except for essential portions.

伸長機構(図4〜図6参照)
図4〜図6に分割パネル5とジャッキ部6及び摺動・固定部7からなる「伸長機構」との配設関係を示す。
以下に下部分割パネル5Bと上部分割パネル5Cとにおける「伸長機構」の配設関係を例に採って説明するが、その他の分割パネル5の相互間の配設関係はこれに準じる。
Extension mechanism (see FIGS. 4 to 6)
FIG. 4 to FIG. 6 show the arrangement relationship between the divided panel 5 and the “extension mechanism” composed of the jack portion 6 and the sliding / fixing portion 7.
In the following, the arrangement relationship of the “extension mechanism” in the lower division panel 5B and the upper division panel 5C will be described as an example, but the arrangement relationship between the other division panels 5 conforms to this.

(ジャッキ部6)(図4、図5参照)
ジャッキ部6は、下部分割パネル5Bと上部分割パネル5Cとの相対峙する端面に配され、かつは分割パネル5の奥行き幅(z軸)方向に対称を保って配される。すなわち、該ジャッキ部6が単一であれば中央に、2つであれば中心線より対称位置に、3つであれば中央及び該中央の対称位置に配される。本実施形態では2つの態様を採る。
そして、該ジャッキ部6は、下部・上部分割パネル5B、5Cの各フランジ11に開設されたボルト挿通孔(図5参照)に挿通されるねじ杆15を主体とし、下部分割パネル5Bの端部フランジ11に固設されるナット部材16、上部分割パネル5Cの端部フランジ1及び該フランジ11に平行するリブ12に挟着固設されるねじ杆受け17からなる。
ねじ杆15は、ねじ部15a、回動部15b、先端部15cよりなり、ねじ部15aはナット部材16のねじ孔に螺合され、回動部15bの回動操作をもって進退動する。ねじ杆15の進出により先端部15cはねじ杆受け17内のリブ12の下面に当接し、下部・上部分割パネル5B、5Cの相互を引き離す作用(伸長作用)をなす。ねじ杆15の逆回動によりねじ杆15は退動し、先端部15cはリブ12の下面より離れ、下部・上部分割パネル5B、5Cの相互の突っ張り力は喪失する。
なお、ねじ杆受け17は適宜省略可能である。更にはリブ12を省略できる。この場合、ねじ杆15の先端部15cはフランジ11の下面に当接する態様を採る。
(Jack part 6) (refer FIG. 4, FIG. 5)
The jack portion 6 is disposed on the end surface where the lower divided panel 5B and the upper divided panel 5C face each other, and is arranged symmetrically in the depth width (z-axis) direction of the divided panel 5.

The screw portion 15a is screwed into the screw hole of the nut member 16, and moves forward and backward with a rotation operation of the rotation portion 15b. As the screw rod 15 advances, the tip 15c comes into contact with the lower surface of the rib 12 in the screw rod receiver 17, and acts to pull the lower and upper divided panels 5B and 5C away from each other (extension function). The screw rod 15 is retracted by the reverse rotation of the screw rod 15, the tip portion 15c is separated from the lower surface of the rib 12, and the tension force between the lower and upper divided panels 5B and 5C is lost.
The screw rod receiver 17 can be omitted as appropriate. Furthermore, the rib 12 can be omitted. In this case, the tip 15c of the screw rod 15 is in contact with the lower surface of the flange 11.

これらのフレーム体1の下底部の固定部26、載置部27に枕材56をライニング管Rの管軸方向に設置する。枕材56は人孔Qからの搬入のために短尺の分割体の態様を採るが、実施において分割体を適宜に継ぎ足して長尺のものとする。
(2) The support system S is installed in the lining pipe R.
That is, first, the divided panels 5 (5A, 5B, 5C, 5D) of the frame body 1 and the height-adjusting support 2 in the contracted state, and further the pillow material 56 are inserted into the lining pipe R through the opening O of the human hole Q. It is brought in.
(2A) Assembly and expansion of frame body 1 In the lining pipe R, the divided panels 5 (5A, 5B, 5C, 5D) of the frame body 1 are assembled and the flanges 11 of the divided panels 5 are brought into contact with each other. Are temporarily fixed by tightening the fixing tool 21 of the sliding / fixing portion 7. The frame body 1 takes a minimum size by the assembly.
In this minimum frame body 1, the frame body 1 is brought into close contact with the inner surface of the lining pipe R by rotating and pushing the screw rod 15 of the jack portion 6 of the “extension mechanism” and by operating the fixture 21 of the sliding / fixing portion 7. The frame body 1 is assembled to a predetermined size.
Thereby, the frame body 1 is closely arranged on the inner surface of the lining pipe R.
(2B)
A plurality of the frame bodies 1 are installed in the tube axis direction of the lining pipe R with appropriate intervals.
(2C)
Pillow members 56 are installed in the tube axis direction of the lining pipe R on the fixing part 26 and the mounting part 27 at the lower bottom of these frame bodies 1. The pillow material 56 takes the form of a short divided body for carrying in from the human hole Q, but in the implementation, the divided body is appropriately added to make it a long one.

(3) 高さ調整支柱2の設置
以上の複数のフレーム体1の設置、及び該フレーム体1間に枕材56の設置がなされた状態において、高さ調整支柱2を各フレーム体1内部の所定位置に設置する。高さ調整支柱2は当初は上部支柱30が下方に収縮されており、この収縮状態で、該高さ調整支柱2の下部支柱31をフレーム体1の底部の固定部26に締結具43をもって締結する。次いで、中間支柱32をハンドル45をもって回動して上部支柱30を上方に伸長させ、上部支柱30の上端の受座36をフレーム体1の把持部23に嵌め込み、把持部23と受座36とを締結具38をもって締結する。
このとき、ライニング管Rの天井部はその自重により若干の凹みをなし変形を有するが、ライニング管Rは方形状を保持するフレーム体1に内面より支持され、該ライニング管Rは変形が補正されて方形状を保持する。これにより、フレーム体1はライニング管Rの内面に密接して配される。
各フレーム体1及び高さ調整支柱2を上記手順により、ライニング管R内で所定間隔をもって順次設置する。
(3) Installation of height adjustment struts 2 In the state where the plurality of frame bodies 1 are installed as described above and the pillow material 56 is installed between the frame bodies 1, the height adjustment struts 2 are installed inside the frame bodies 1. Install in place. In the height adjustment column 2, the upper column 30 is initially contracted downward, and in this contracted state, the lower column 31 of the height adjustment column 2 is fastened to the fixing portion 26 at the bottom of the frame body 1 with a fastener 43. To do. Next, the intermediate strut 32 is rotated with the handle 45 to extend the upper strut 30 upward, and the receiving seat 36 at the upper end of the upper strut 30 is fitted into the gripping portion 23 of the frame body 1. Is fastened with a fastener 38.
At this time, the ceiling portion of the lining pipe R is slightly dented and deformed by its own weight, but the lining pipe R is supported from the inner surface by the frame body 1 holding a square shape, and the deformation of the lining pipe R is corrected. Hold the square shape. Thereby, the frame body 1 is closely arranged on the inner surface of the lining pipe R.
Each frame body 1 and the height adjustment column 2 are sequentially installed in the lining pipe R at a predetermined interval by the above procedure.

(4) 反力部材3の設置
上記工程(3) と同時に、反力部材3を搬入し、各フレーム体1において該反力部材3を設置する。すなわち、フレーム体1の所定位置すなわちフレーム体1の底部の載置部27において、該載置部27上に載置された枕材56に反力部材3の台座60を載置し、柱部55が設置される。更には、各反力部材3の設置位置のライニング管Rの天井部に反力部材3の円管柱58の挿通用の孔hが穿孔される。
挿通用の孔hの穿孔は、ライニング管Rの天井部における塑性変形材(金属)の位置を避けてなされるが、その場合、反力部材3の位置も枕材56に沿って変更される。
(4) Installation of the reaction force member 3 Simultaneously with the step (3), the reaction force member 3 is carried in and the reaction force member 3 is installed in each frame body 1. That is, at a predetermined position of the frame body 1, that is, at the placement portion 27 at the bottom of the frame body 1, the base 60 of the reaction member 3 is placed on the pillow material 56 placed on the placement portion 27. 55 is installed. Further, a hole h for insertion of the circular pipe column 58 of the reaction force member 3 is formed in the ceiling portion of the lining pipe R at the installation position of each reaction force member 3.
The insertion hole h is perforated while avoiding the position of the plastic deformation material (metal) in the ceiling portion of the lining pipe R. In this case, the position of the reaction member 3 is also changed along the pillow material 56. .

(4A)
回動管59を回動してその上部の円管柱58を上方に押し上げ、更には、円管柱58を前記したライニング管Rの天井部の孔hを介して外方へ繰り出してその先端面を下水道管渠Pの天井面に押し付ける。その反力は反力部材3の柱部55、枕材56を介してフレーム体1に伝達され、結果としてライニング管Rは管渠P内の下底に押し付けられる。円管柱58のライニング管Rの天井部の孔hの外方部分には予めセメントミルクとの剥離剤が塗布される。
この作用により、セメントミルクMの注入(後述)において、ライニング管Rは浮力を受けることになるが、反力部材3はこの浮力に抗してライニング管Rは常時管渠P内の下底に押し付けられる。
(4A)
The rotary tube 59 is rotated to push the upper circular tube column 58 upward, and further, the circular tube column 58 is extended outwardly through the hole h in the ceiling portion of the lining tube R and the tip thereof. Press the surface against the ceiling surface of the sewer pipe P. The reaction force is transmitted to the frame body 1 through the pillar portion 55 and the pillow material 56 of the reaction force member 3, and as a result, the lining pipe R is pressed against the lower bottom in the pipe rod P. A release agent for cement milk is applied in advance to an outer portion of the hole h in the ceiling portion of the lining pipe R of the circular pipe column 58.
Due to this action, the lining pipe R receives buoyancy when the cement milk M is injected (described later), but the reaction force member 3 resists this buoyancy and the lining pipe R is always on the lower bottom in the pipe rod P. Pressed.

(5) セメントミルクMの注入
ライニング管Rの両端に、管渠Pとライニング管Rとの間隙を塞ぐ目張り工Vを施こし、該目張り工Vを貫通する注入管を介して下水道管渠Pとライニング管Rとの間隙にセメントミルクMを所定の圧力のもとに注入充填する。
セメントミルクMの充填によりライニング管Rは浮力と側圧を受け、矩形(すなわち方形)状のライニング管Rに変形(幅方向の圧縮、高さの増加)を与えるが、本ライニング管Rの高さ調整支柱2の拘束作用によりフレーム体1は方形状を保持し、これによりライニング管Rの変形が阻止される。
(5) Injection of cement milk M A lining pipe V that closes the gap between the lining pipe R and the lining pipe R is applied to both ends of the lining pipe R, and the sewer pipe tub P is passed through the injection pipe that penetrates the lining pipe V. The cement milk M is injected and filled in the gap between the lining pipe R and the lining pipe R under a predetermined pressure.
The lining pipe R receives buoyancy and lateral pressure by filling with the cement milk M, and deforms the rectangular (that is, rectangular) lining pipe R (compression in the width direction and increases the height). The height of the lining pipe R Due to the restraining action of the adjustment support 2, the frame body 1 maintains a square shape, and this prevents the lining pipe R from being deformed.

(6) 支保工装置Sの解体
セメントミルクMの固設を待って、あるいは所定の強度が発現したところで本支保工装置Sの解体をなす。
(6A)
先ず、反力部材3の解体をなす。すなわち、回動管59を回動して降下させて円管柱58から引き離し、台座60とともに撤去し、更に円管柱58を引き下ろし、これらの全て及び枕材56を撤去する。
(6B)
しかる後、本支保工装置Sにおいて、高さ調整支柱2とフレーム体1との締結具38,43の締結を解除し、高さ調整支柱2の上部支柱30を引き下げてその受座36をフレーム体1の把持部23から外し、高さ調整支柱2の下端部をフレーム体1の固定部26から外し、高さ調整支柱2を撤去する。
次いで、フレーム体1において、「伸長機構」のジャッキ部6のねじ杆15、摺動・固定部7の固定具21を緩めて各分割パネル5の各パネル5A,5B,5C,5Dの係合を解き、各フレーム体1を解体し、フレーム体1を人孔Qの開口を介して外部に搬出する。
これにより、ライニング管Rの下水道管渠Pへの設置施工は完了する。
なお、上記手順(6A)、(6B)において、反力部材3、枕材56の撤去に先んじて高さ調整支柱2をの撤去することを妨げない。
(6) Dismantling of the supporting device S The supporting device S is disassembled after the cement milk M is fixed or when a predetermined strength is developed.
(6A)
First, the reaction force member 3 is disassembled. That is, the rotating tube 59 is rotated and lowered to be separated from the circular tube column 58, removed together with the pedestal 60, the circular tube column 58 is further pulled down, and all of these and the pillow material 56 are removed.
(6B)
After that, in this supporting apparatus S, the fastening of the fasteners 38 and 43 between the height adjusting column 2 and the frame body 1 is released, the upper column 30 of the height adjusting column 2 is pulled down, and the seat 36 is attached to the frame. The body 1 is removed from the grip 23, the lower end of the height adjustment column 2 is removed from the fixing unit 26 of the frame body 1, and the height adjustment column 2 is removed.
Next, in the frame body 1, the screw rod 15 of the jack portion 6 of the “extension mechanism” and the fixture 21 of the sliding / fixing portion 7 are loosened to engage the respective panels 5 A, 5 B, 5 C, 5 D of each divided panel 5. , Each frame body 1 is disassembled, and the frame body 1 is carried outside through the opening of the human hole Q.
Thereby, the installation construction to the sewer pipe P of the lining pipe R is completed.
