Description

【０００１】
【産業上の利用分野】
この発明はガス導管、下水道管、上水道管、その他導管の敷設管路等の地中に埋設された管路、集合住宅やホテル等高層建築物内の管路に、その内面に筒状の内し、硬化性樹脂材を圧着する管のライニング方法に関するものである。
【０００２】
【従来の技術】
従来、管路のライニング方法にはガス導管、下水道管、その他の導管において、大口径に適した方法が重点的に開発されてきたが、アパート、マンション、ホテル等、集合住宅や高層建築物に敷設された違径管の連続管や、枝管、曲がり管等の多い下水道管、ガス管等の管路に対する樹脂ライニングについての要望が多いにも拘わらず、とくに、違径管の連続管への管路内樹脂ライニングの技術開発が遅れている。
【０００３】
【発明が解決しようとする課題】
従来のライニング工法に使用されている管ライニング材は、筒状の樹脂吸収材の外周面を合成樹脂あるいはゴム等の弾性体チューブを一重に被覆したものが一般的であった。しかしながら、施工時に使用する圧力調整金具のパイプへの挿入端部が、すじ状に極端に伸びる（図６の従来型ライニング材の弾性体チューブ膨張テストにおいて符号Ａに示す部分）恐れがあり、管路の内面を確実に被覆できないことがあった。また、管路の内径に略等しいか、やや小さい径の管ライニング材を使用して管路のライニングを施工する場合に、加圧式反転装置と管ライニング材を接続するガイドホースの口径を管路の径と同じにして施工すると、管路の内張面に弾性体チューブのしわが残り易い。さらに、加圧式反転装置による管路のライニング工事において、管路に曲がり管（エルボ）が配設されている場合、曲がり管内の内角の面に牽引ロープ、及び反転速度調節ロープの摩擦による凹みや傷がついてしまう、等種々の難点があった。
【０００４】
この発明は上記難点を解消するために開発されたものであり、円滑、かつ確実に施工できる管のライニング方法を提供することを目的としている。
【０００５】
【課題を解決するための手段】
前記目的を達成するために本発明では、合成樹脂やゴム等の弾性体チューブを二重以上復数枚重合して筒状に形成し、該弾性体チューブの外周面に織布又は不織布による樹脂吸収材を被覆してライニング材を形成し、該ライニング材の長さ方向両端部に圧力調整金具を差し込み結束して密封し、一方、施工すべき管路内に牽引ロープを挿入しておき、該ロープの端部とライニング材の一端部を連結し、硬化樹脂前記樹脂吸収材部分に含浸させながら、牽引ロープによってライニング材を管路内に引き込んで所定の位置に配置し、前記圧力調整金具にバルブや調整機器を取付け、圧力調整機器より圧力液体を注入して弾性体チュウーブを膨張せしめてライニング材を管路内周面に圧着せしめ、硬化性樹脂の硬化後、弾性体チューブのみを管路内より引き抜くことを特徴とし、又、織布、不織布による樹脂吸収材を筒状に形成し、該樹脂吸収材の外周面に合成樹脂やゴム等の弾性体チューブを二重以上復数枚重合し被覆してライニング材を形成し、該ライニング材はその樹脂吸収材部分の中に牽引ロープを挿通し、かつ樹脂吸収材の一端より硬化性樹脂を含浸させて一端部を結束固定し、ガイドホースを介して施工すべき管路と連結した加圧反転装置を使用し、該加圧反転装置のドラムに巻設してある反転調節ロープと前記ライニング材の一端部に連結し、加圧反転装置の内部にライニング材を巻き取り、ライニング材の終端部を加圧反転装置の反転始端部に固定し、ライニング材の終端部から突出している牽引ロープを、予め管路内、及びガイドホースに挿通しておいた牽引ロープに連結し、加圧反転装置内へ液体圧力をかけて、管路内にてライニング材を反転せしめるとともに、管路内に挿通した牽引ロープを引き、反転終了後、一定の圧力を保持した状態で硬化性樹脂を硬化させ、弾性体チューブを引き抜き管路内周面に樹脂膜を形成することを特徴としたものであり、さらに、施工すべき管路の内径に略等しいか、やや小さ径のライニイング材を使用する管のライニング方法において、管路の内径よりも大きいガイドホースを使用することを特徴とし、そしてさらに、異径管の連続した管路を施工する管のライニング工法において、管路径の小さい径に合わせたライニング材を使用し、かつ管路径の大きな方から反転を開始することを特徴としたものである。
【０００６】
【発明の実施の形態】
以下、図示した実施の形態例に基づいて説明する。図１において符号１は本発明に使用するライニング材を示すものである。このライニング材１は、合成樹脂やゴム等の弾性体チューブ２を二重以上複数枚重合して筒状に形成し、該弾性体チューブ２の外周面に織布又は不織布による筒状の樹脂吸収材３を被覆したものである。
【０００７】
図１に示すように、前記ライニング材１の長さ方向両端部に圧力調整金具４を差し込み、紐やバンド５で締め付け密封し、図２に示すように、予め、管路内に牽引ロープ８を挿通しておきライニング材の一端部と連結し、ライニング材１を、硬化性樹脂６を含浸させながら滑車７を介して牽引ロープ８で管路内に引き込み、所定の位置に配置する。そして、前記圧力調整金具４にバルブや圧力調整機器（図示せず）を取付け圧力調整機器より圧力流体を挿入し、弾性体チューブ２を膨張せしめ、管路内面にライニング材１を圧着させ、一定の圧力を保持した状態で硬化させる。硬化性樹脂６の硬化を確認後、管路内の弾性チューブ２を引き抜き、管路内に硬化性樹脂膜を被覆する。竪管等に適した管ライニング方法である。
【０００８】
図３は加圧反転によるライニング工事に使用するライニング材９を示すものである。このライニング材９は、樹脂吸収材３の外周面に、二重あるいは二重以上の複数枚重合した筒状の弾性体チューブ２，２を被覆したものである。そして、このライニング材９の内部に牽引ロープ１０を挿通する。
【０００９】
前記ライニング材９における樹脂吸収材３に硬化性樹脂６を含浸させ、ライニング材９の長手方向一端部を密封し、前記牽引ロープ１０と共に結束固定して反転終端部９ａとなし、図４に示す加圧反転装置１１の中のドラム１３に巻いてある反転速度調節ロープ１２と前記牽引ロープ１０を結んで繋ぎ、加圧反転装置１１内に配設してあるドラム１３に巻き取り、ライニング材９の反転終端部９ａを加圧反転装置１１の反転始端部１１ａに配置し、ライニング材９の反転終端部９ａから突出している牽引ロープ１０を予め管路内１５，１６，１７及びガイドホース１２に挿通しておいた牽引ロープ１８と連結する。
【００１０】
前記ガイドホース１４を加圧反転装置１１に連結固定した後、加圧反転装置１１の中へ圧力液体Ｂを送入すれば、加圧しながらライニング材９は反転を開始し、ガイドホース１４から管路１５，１６，１７と反転、推進して行く。反転と同時に管路末端より牽引ロープ１８を弱い力で引き、予め牽引ロープ１８に付けてある長さの目印を見ながら、反転の距離を確認する。
【００１１】
反転終了後、一定の加圧をかけた状態で、硬化性樹脂６を硬化させ、硬化の確認後、管路内部の弾性体チューブ２，２を引き抜き、管路の内周面に樹脂膜１９を形成する。
【００１２】
図４に示すように異径管の連続連続した管路における施工の場合には、ガイドホース１４の口径を管路１５の口径より大きくすれば、皺が全くなる。このことからして、本発明では、管路が異径管の連続管の場合に、口径の大きい管路１５から管路１７に向けて加圧式反転ライニングを行う。
【００１３】
加圧式反転装置による管路のライニング工事において管路に曲がり管（エルボ）が存在する場合には、図５に示すように、前記牽引ロープ１０及び反転調節ロープ１２の表面に管路の内径より小径の柔軟性合成樹脂の被覆チューブ１９を被覆し、該被覆チューブの長手方向両端部を前記ロープ１０，１２に粘着テープ２０などで固定する。
【００１４】
【發明の効果】
以上のような方法からなる本発明は以下の効果をする。
すなわち、樹脂吸収材に合成樹脂やゴム等の弾性体チューブを二重又は二重以上重ね合わせたライニング材を使用することにより、膨張時におけるライニング材の表面力の平均化が保持でき、より膨張力を上げることができる。又、加圧式ライニング工法においては、反転の滑りを良くし、工事中の弾性体チューブの傷や破損のトラブルを減らし、工事の確実性を高めることができる。
【００１５】
管路の内径に略等しいか、やや小さい径のライニング材をを使用して管路ライニングを施工する場合に、加圧式とライニング材を接続するホースの口径を同じくして施工すると、管路の内張面にに皺ができ易かったが、ホースの口径を管路の口径より大きくすることにより、ライニング材の弾性体チューブ部分にテンションが生じて内張面にしわが生じなくなる。
【００１６】
さらに、加圧式反転装置による曲り管のあるライニング工事において、曲り管の内閣の面に牽引ロープ及び反転速度調節ロープの摩擦による凹みや傷がつき易いが、前記ロープに被覆チューブを取付けることにより、凹みや傷のつくことを防止できることを、経済的にも安価な方法で可能にした。

[Problems to be solved by the invention]
The pipe lining material used in the conventional lining method is generally one in which the outer peripheral surface of the cylindrical resin absorbent material is covered with an elastic tube such as a synthetic resin or rubber. However, there is a possibility that the insertion end of the pressure adjusting fitting used at the time of construction into the pipe will extend extremely in a streak shape (the portion indicated by symbol A in the elastic tube expansion test of the conventional lining material in FIG. 6). In some cases, the inner surface of the road could not be reliably covered. Also, when pipe lining is constructed using pipe lining material with a diameter that is approximately the same as or slightly smaller than the pipe inner diameter, the diameter of the guide hose that connects the pressure inverting device and the pipe lining material is set to the pipe line. If the diameter is set to be the same as the diameter of the tube, wrinkles of the elastic tube are likely to remain on the lining surface of the pipeline. Furthermore, in the lining work of the pipe line by the pressurization type reversing device, when a bent pipe (elbow) is arranged in the pipe line, there is a dent caused by friction of the traction rope and the reverse speed adjusting rope on the inner angle surface in the bent pipe. There were various difficulties such as scratches.

In the street It is characterized by being pulled out, and a resin absorbent material made of woven or non-woven fabric is formed into a cylindrical shape, and an elastic tube such as a synthetic resin or rubber is polymerized on the outer peripheral surface of the resin absorbent twice or more times. A lining material is formed by coating, and a traction material is inserted into the resin absorbent material portion of the lining material, and one end portion of the resin absorbent material is impregnated with a curable resin, and one end portion is bound and fixed. A pressure reversing device connected to the pipe line to be constructed via the pressure reversing adjustment rope wound around the drum of the pressure reversing device and one end of the lining material, and the pressure reversing device The lining material is wound inside, the terminal end of the lining material is fixed to the reversing start end of the pressure reversing device, and the tow rope protruding from the terminal end of the lining material is inserted into the pipe and the guide hose in advance. To the tow rope As a result, liquid pressure is applied to the pressure reversing device to reverse the lining material in the pipeline, and pulling the tow rope inserted into the pipeline and holding a constant pressure after the reversal is completed. It is characterized by curing the curable resin, pulling out the elastic tube, and forming a resin film on the inner peripheral surface of the pipeline, and further, having a diameter substantially equal to or slightly smaller than the inner diameter of the pipeline to be constructed. In the lining method of the pipe using the lining material, a guide hose that is larger than the inner diameter of the pipe line is used, and further, in the pipe lining method for constructing a continuous pipe line of different diameter pipes, the pipe diameter This is characterized by using a lining material having a small diameter and starting the reversal from the larger pipe diameter.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, description will be made based on the illustrated embodiment. In FIG. 1, reference numeral 1 denotes a lining material used in the present invention. This lining material 1 is formed by forming a cylindrical shape by polymerizing a plurality of elastic tubes 2 such as synthetic resin and rubber, and absorbing the cylindrical resin by a woven fabric or a non-woven fabric on the outer peripheral surface of the elastic tube 2. The material 3 is covered.
[0007]
As shown in FIG. 1, pressure adjusting fittings 4 are inserted into both ends in the longitudinal direction of the lining material 1 and tightened and sealed with a string or a band 5. As shown in FIG. Is inserted into one end of the lining material, and the lining material 1 is drawn into the pipe line by the traction rope 8 through the pulley 7 while being impregnated with the curable resin 6 and disposed at a predetermined position. Then, a valve or a pressure adjusting device (not shown) is attached to the pressure adjusting fitting 4, and a pressure fluid is inserted from the pressure adjusting device, the elastic tube 2 is inflated, and the lining material 1 is pressure-bonded to the inner surface of the pipe line. Curing is performed while maintaining the pressure. After confirming the curing of the curable resin 6, the elastic tube 2 in the conduit is pulled out and a curable resin film is coated in the conduit. This is a pipe lining method that is suitable for pipes and the like.
[0008]
FIG. 3 shows the lining material 9 used for the lining work by pressure reversal. The lining material 9 is obtained by coating the outer peripheral surface of the resin absorbent material 3 with cylindrical elastic tubes 2 and 2 in which a plurality of double or double layers are superposed. Then, the traction rope 10 is inserted into the lining material 9.
[0009]
The resin absorbent material 3 in the lining material 9 is impregnated with a curable resin 6, one end in the longitudinal direction of the lining material 9 is sealed, and is bound and fixed together with the traction rope 10 to form a reverse terminal portion 9a, as shown in FIG. The reversing speed adjusting rope 12 wound around the drum 13 in the pressure reversing device 11 is connected to the traction rope 10 and is wound around the drum 13 disposed in the pressure reversing device 11. The reversing end portion 9a is arranged at the reversing start end portion 11a of the pressure reversing device 11, and the traction rope 10 protruding from the reversing end portion 9a of the lining material 9 is previously placed in the pipelines 15, 16, 17 and the guide hose 12. It connects with the traction rope 18 which has been inserted.
[0010]
After the guide hose 14 is connected and fixed to the pressure reversing device 11, if the pressure liquid B is fed into the pressure reversing device 11, the lining material 9 starts reversing while being pressurized, and the pipe from the guide hose 14 Turn over to roads 15, 16, and 17 and push forward. Simultaneously with the reversal, the pulling rope 18 is pulled with a weak force from the end of the pipeline, and the reversing distance is confirmed while looking at the mark of the length previously attached to the pulling rope 18.
[0011]
After completion of the reversal, the curable resin 6 is cured in a state where a certain pressure is applied. After confirmation of the curing, the elastic tubes 2 and 2 inside the pipe are pulled out, and a resin film 19 is formed on the inner peripheral surface of the pipe. Form.
[0012]
As shown in FIG. 4, in the case of construction in a continuous continuous pipe of different diameter pipes, if the diameter of the guide hose 14 is made larger than the diameter of the pipe 15, wrinkles are completely formed. Therefore, in the present invention, when the pipe is a continuous pipe having a different diameter, the pressure-type reversal lining is performed from the pipe 15 having a large diameter toward the pipe 17.
[0013]
When a bent pipe (elbow) is present in the pipe line in the lining work of the pipe line by the pressurization type reversing device, as shown in FIG. A coated tube 19 of a small-diameter flexible synthetic resin is coated, and both ends in the longitudinal direction of the coated tube are fixed to the ropes 10 and 12 with an adhesive tape 20 or the like.
[0014]
[Effect of Dawn]
The present invention comprising the above method has the following effects.
In other words, by using a lining material made of double or double elastic tubes such as synthetic resin and rubber for the resin absorbent material, the surface force of the lining material during the expansion can be kept average and more expanded. You can increase your power. Further, in the pressure type lining construction method, the reversal slip can be improved, the trouble of the elastic tube during the construction can be reduced, and the reliability of the construction can be improved.
[0015]
When pipe lining is constructed using a lining material with a diameter that is approximately equal to or slightly smaller than the inner diameter of the pipe line, if the same pressure is applied to the hose connecting the lining material, Although it was easy to make wrinkles on the lining surface, when the diameter of the hose is made larger than the diameter of the pipe line, tension is generated in the elastic body tube portion of the lining material and wrinkles are not generated on the lining surface.
[0016]
Furthermore, in the lining work with the bent pipe by the pressurization type reversing device, the surface of the bent pipe cabinet is likely to be dented or scratched by the friction of the pulling rope and the reverse speed adjusting rope, but by attaching a covering tube to the rope, It was possible to prevent dents and scratches from occurring in an economical and inexpensive manner.
