る管継手の接続方法の開発が望まれている。(Problem to be Solved by the Invention) However, since the above-mentioned conventional branch connection pipe joint usually has a smooth joint surface at its saddle portion, such a branch connection pipe joint is not suitable for ribbed pipes as described above. However, the numerous annular ribs on the outer circumferential surface become a hindrance to the application, making it impossible to use the entire pipe.Therefore, branch connections between the ribbed pipe and the numerous branch pipes can be easily and reliably performed on site. It is desired to develop a method for connecting pipe joints.
本発明は、そのような要望に応えるべくなされたもので
ある。The present invention has been made to meet such demands.

とができる。Note that the joint surface between the spacer 1 and the ribbed tube 2 and the spacer 1
A water-expandable elastic body that absorbs water and expands when it comes into contact with water may be interposed at the joint surfaces between the pipe joint 3 and the branch connecting pipe joint 3 to prevent water leakage at each joint surface. For example, when a water-expandable elastic body is interposed between the joint surface of the spacer 1 and the ribbed tube 2, as shown in FIG. It is preferable that a ring 5 made of a water-expandable elastic body is fixed to the inner circumferential surface via a groove 51. When fixing such a spacer 1 to the ribbed tube 2, the area from the branch hole 4 to the ring 5 is fixed by applying adhesive only to the outside of the ring 5 on the inner peripheral surface of the spacer 1. Preferably, a slight water channel is formed in between so that the ring 5 is expanded by the sewage flowing inside the tube. Further, the connection method of the present invention can be applied not only to the ribbed tube 2 described above but also to a corrugated tube in which a large number of corrugated portions are formed on the tube wall.
