MULTISTAGE PIPE, MULTISTAGE DRAIN PIPE, CONSTRUCTION METHOD OF MULTISTAGE DRAIN PIPE, AND DRAIN STRUCTURE OF MULTISTAGE DRAIN PIPE
To provide a multistage pipe which can confront a compressive force, a multistage drain pipe, a construction method of a multistage drain pipe, and a drain structure of a multistage drain pipe.SOLUTION: A multistage pipe (multistage drain pipe 1) includes a plurality of pipe bodies (outer pipe 2, inner pipe 3 and intermediate pipe 13) having different pipe diameters, and enables other pipe bodies to be stored in the outer pipe 2 having the largest pipe diameter among the plurality of pipe bodies, and has engagement mechanisms 6 to 11 that engage the pipe bodies against a compressive force acting in a direction of shrinking and compressing the pipe bodies in stretching provided between the plurality of pipe bodies.SELECTED DRAWING: Figure 3
【課題】圧縮力にも対抗することができる多段式パイプ、多段式排水パイプ、多段式排水パイプの施工方法、及び多段式排水パイプの排水構造を提供する。【解決手段】管径の異なる複数の管体（外管２，内管３，中間１３）を備え、これらの複数の管体のうち一番管径の大きな外管２に他の管体が収納可能な多段式パイプ（多段式排水パイプ１）において、前記複数の管体同士の間に、延伸したときに互いの管体同士を縮めて圧縮する方向に作用する圧縮力に対抗して管体同士を係止する係止機構６〜１１を設ける。【選択図】図３
