ぎ管の推進埋設作業を円滑に進められるものである。Since the intermediate pushing device of the present invention has the above-described structure, in the propulsion method, the intermediate pushing jack (3) is operated to sequentially push the conch pipe (') into the soil. The operation of this jack (,?) is repeated several hundred times or more, depending on the length of the pipe laid, and therefore the friction between the intermediate push sleeve (2) and the insertion side of the concrete pipe (1)' In addition, it is necessary to completely prevent water leakage and mud leakage, and as in the present invention, several water-stop rubber rings (6) provided on the cylindrical surface are provided around the circumference of the concrete pipe (ly) on the inlet side. Must-have piece (6) for securing the front and rear metal
・) to ensure complete watertightness by preventing damage to the surface of the concrete pipe (ly) and preventing movement and deformation of the rubber ring.
This prevents serious accidents such as ground cave-ins caused by mud leakage, and facilitates pipe burying work.
