    • PROBLEM TO BE SOLVED: To provide a wall construction device for the circumference of a pipe capable of constructing a homogeneous wall around the pipe and, at the same time, shortening a construction period of time at a low cost.
      SOLUTION: A circular opening section of a gutter pipe is closed by the whole circumferential seal 1 to separate the ground G from the inside of the gutter pipe Z, the whole circumferential seal 1 is pushed away by a guide holding section 11a of a holding member 11 to project a guide member 14 in the direction of F. After a cutter 15 is projected in the direction of the F along the guide member 14 by a cylinder 16 for coming in and out, the cutter 15 is turned in the direction Q by a turning unit 2 to make it eat into the ground, and while moving the cutter 15 in the direction of D along the guide member 14 in a state to remain unchanged, the ground G is excavated to form a trench M and, at the same time, the inside of the trench M is injected and filled with a kickback material Y from injection pipes 17a and 17b. When such a series of processes are repeatedly carried out, finally the circular trench M filled with the kickback material Y around the gutter pipe Z is formed, and then, when the kickback material Y is solidified, the circular wall is constructed around the gutter pipe Z.

    • 要解决的问题:提供一种能够围绕管道构造均匀壁的管道的周边的壁式施工装置,同时以较低的成本缩短施工周期。

      解决方案:通过整个圆周密封件1将沟槽管的圆形开口部分封闭,以将地面G与沟槽管Z的内部分开,整个周向密封件1被引导保持部分11a 保持构件11,使引导构件14沿F方向突出。在切割器15沿着引导构件14的方向沿着F的方向通过用于进出的气缸16突出之后,切割器15在 方向Q通过转动单元2使其进入地面,并且在保持不变的状态下沿着导向构件14在D方向上移动切割器15的同时,挖掘地面G以形成沟槽M, 同时,从注射管17a和17b注入沟槽M的内部并填充反冲材料Y. 当重复进行这样的一系列处理时,最终形成在沟槽管Z周围填充反冲材料Y的圆形沟槽M,然后,当反冲材料Y固化时,围绕该沟槽管 (C)2005,JPO&NCIPI
