し、止水をおこなうようにしている。 Currently, when concrete pipes are being pushed underground, rubber rings having a structure as shown in Figures 1 and 2 are used to stop water at the joints. That is,
A groove b or a step c is provided around the end of the concrete pipe a, or a step c is provided on one side in the direction of propulsion, and an annular rubber ring d having a semicylindrical or other shape in cross section is fitted into this, and a special force is applied to the end of the concrete pipe a. When this occurs, the lower surface of the rubber ring d is adhered to the concrete pipe a, and the protrusion of the rubber ring d is brought into contact with the inner wall of the steel collar e to stop water.

いう問題点があつた。 However, in such a method, the rubber ring d is not completely fixed, and when the pipes are joined together, the rubber ring d is turned over, causing water leakage. In addition, in the case of an intermediately pushed pipe, the steel collar and concrete pipe slide back and forth hundreds of times by the intermediate jack, so a tensile force is applied to the rubber ring back and forth each time, causing grooves or Accidents of falling off the stepped section often occur. If the rubber ring comes off in this way, it not only causes water leakage as mentioned above, but also causes meandering of the pipe and an increase in propulsion force, which has a serious impact on the success or failure of the construction work. It was hot.
本考案は前記事情に鑑みてなされたもので前記
