（発明が解決しようとする課題） しかしながらこの発明者等が明らかにした実開昭56−
157492号公報に開示の水道管の補修方法は、本管の水道
の流れを停止させる必要がない、最低限の水道の供給を
停止する影響のみで修理ができるなど、なるほどすぐれ
た方法ではあるが、操作棒の内筒、外筒とも屈曲自在と
されていないため、操作棒を中空分岐管の直管部から差
し込んで止水作業を行い、止水作業終了後は止水駒を直
管部先端に固定しなければならない。(Problems to be solved by the invention)
Although the method of repairing water pipes disclosed in Japanese Patent No. 157492 is an excellent method, it is not necessary to stop the flow of water in the main pipe, and repair can be performed only by stopping the supply of minimum water supply. Since the inner and outer cylinders of the operation rod are not bendable, the operation rod is inserted from the straight pipe section of the hollow branch pipe to perform the water stop operation, and after the water stop operation is completed, the water stop piece is connected to the straight pipe section. Must be fixed to the tip.
このために止水作業を終えた水道管内では水道水の流
れが補修箇所で屈曲することとなるため、水道水の流れ
に抵抗が生じ、例えば、高所や或いは団地等の水圧を必
要とする所の分岐管ではその流通抵抗分だけ、家庭内で
の水道水の供給圧に影響が生じるという課題が存在し
た。For this reason, since the flow of tap water is bent at the repair location in the water pipe after the water stoppage work, resistance occurs in the flow of tap water, for example, water pressure at a high place or an apartment complex is required. There is a problem that the supply pressure of tap water in the home is affected by the flow resistance of the branch pipe at the place.
一方、実公昭43−22610号公報に開示の技術にあって
は、本管内を流れる水は略人字状の中空分岐管で屈曲し
ないために水の流れが生じず、水の供給圧に影響が生じ

撓索は他方の鍔金に固着されているために、管体水密部
分から可撓導管と可撓索とを取り外すことができず、破
水水道管の補修をするものとして用いることは好ましく
ない。On the other hand, according to the technology disclosed in Japanese Utility Model Publication No. 43-22610, water flowing in the main pipe does not bend in a substantially human-shaped hollow branch pipe, so that no water flow occurs and the water supply pressure is affected. However, since the flexible conduit is fixed to one collar and the flexible cable is fixed to the other collar, the flexible conduit and the flexible cable are removed from the watertight part of the tube. Therefore, it is not preferable to use it for repairing broken water pipes.
尚、管体水密部分から可撓導管と可撓索とを取り外す
ために、例えばこれら可撓導管と可撓索を切断すると、
弾性水密リングの膨出状態は解除してしまう。In order to remove the flexible conduit and the flexible cable from the watertight portion of the tube, for example, when the flexible conduit and the flexible cable are cut,
The swelling state of the elastic watertight ring is released.

は水圧に抗して弾性水密リングを所定位置に固定する作
業を円滑に行うことができないという課題が存在した。Furthermore, in this technique, since the flexible conduit is formed of a flexible material that easily stretches over its entire length, when the elastic watertight ring is inserted into the pipe to stop the water flow, the water pressure flowing through the pipe causes The flexible conduit is easily wobbled and its position is apt to fluctuate, making it difficult to insert the elastic watertight ring into a predetermined position.Furthermore, work to fix the elastic watertight ring in a predetermined position against water pressure There was a problem that it could not be performed smoothly.
そこで業界では補修後の水道水の流れ抵抗を小さくす

円滑に作業性良く行うことのできる補修方法及び補修具
の創出が望まれていた。Therefore, there has been a demand in the industry for the creation of a repair method and a repair tool that can reduce the flow resistance of tap water after repair and can perform repair work of a broken water pipe extremely smoothly with good workability.

を奏する。(Effects of the Invention) As described in detail above, the present invention is a method for repairing a water pipe that has been broken, in which a through-hole is formed along the center axis of a cylindrical elastic body, and a threaded rod is inserted through the through-hole. A receiving plate abutting on the distal end surface of the elastic body is continuously provided at the distal end of the screw rod, and a washer that abuts on the proximal end surface of the elastic body is loosely fitted in a middle portion of the screw rod, and a proximal end of the screw rod halfway from the washer. Use a water stop piece with a washer and a nut adjacent to the part screwed forward and backward, and an operation rod consisting of a hollow outer cylinder and an inner pipe inserted through this outer pipe when moving and fixing this water stop piece First, remove the soil around the broken water pipe, cut the broken water pipe, insert a water stop into the water pipe on the source side of the cut water pipe, and compress the elastic body via the operating rod. Inflate and fix the water stop piece and stop the tap water with the cut water pipe on the source side. After that, the operation rod is removed from the water stop piece, and then, the straight pipe end of the roughly-shaped hollow branch pipe is connected to this source water pipe, and the straight pipe base end of the hollow branch pipe and the cut water pipe are connected. Connect the downstream side, and further insert an operation rod into the branch pipe portion of this substantially human-shaped hollow branch pipe to engage with the water stopping piece, and release the compressed state of the elastic body through this operation rod. After moving the water stop piece to the base end of the branch pipe section and fixing the water break section, repairing the water break section, removing the operation rod from the water stop piece with the water stop piece fixed to the base end of the branch pipe section Since it is a water pipe repair method, it has the following excellent effects.

水道管補修具であるから以下の優れた効果を奏する。Further, the present invention is a repair tool comprising a substantially human-shaped hollow branch pipe, a water blocking piece, and an operation rod, wherein the substantially human-shaped hollow branch pipe has a straight pipe part and an intermediate part of the straight pipe part. The branch pipe portion is further branched, and at the end of the branch pipe portion, a fixing portion of a water blocking piece is formed, and the water blocking piece is formed along a cylindrical elastic body and a central axis of the elastic body. A threaded rod inserted through the perforated through-hole, a receiving plate abuts on the distal end surface of the elastic body, a washer is loosely fitted on the base end surface, and a nut is adjacent to the washer. The nut is threadably engaged with the screw rod so as to be able to advance and retreat, and the distal end surface of the screw rod has a small diameter portion and a left screw is engraved on the outer peripheral surface. Is engraved with a right-hand thread, and the operating rod comprises a hollow outer cylinder and an inner cylinder inserted through this outer cylinder. The length is set to be at least the length from the tip of the branch pipe portion of the hollow branch pipe to the tip of the straight pipe portion, and the tip of the inner cylinder is screwed with the small diameter portion of the screw tip of the water stop piece. Is engraved and the tip of the outer cylinder is a nut turning part that fits with the nut of the water stopping piece, and the inner cylinder and the outer cylinder of this operation rod are each formed with a gripping part at the base end,
The straight portion from the grip portion to the central portion is a straight tube portion, and the entire length of the straight tube portion is set to at least the length of the branch tube portion of the hollow branch pipe, and the straight tube portion extends from the straight tube portion to the tip end. Since it is a broken water pipe repair tool characterized by having a flexible flexible pipe structure, it has the following excellent effects.
