DOUBLE SHEATH PIPE FOR DRAIN PIPE INSTALLATION AND INSTALLATION METHOD OF NON-EXCAVATION DRAIN PIPE
To provide a double sheath pipe for drain pipe installation capable of being easily pulled out to a departure shaft side while preventing soil from penetrating a space between a drain pipe and itself when excavation of an arrival shaft is impossible.SOLUTION: A double sheath pipe 7 for drain pipe installation to be installed in an adit 2 and pulled out, in which a permeable drain pipe 3 is installed, is provided with an outer sheath pipe 8, a guide pipe 10 driven and installed in the outer sheath pipe 8, and a tail seal 11 cutting-off a gap between the guide pipe 10 and the drain pipe 3, wherein the tail seal 11 is in a cylindrical shape, of which one end part is attached on a tip of the guide pipe 10 in a driven direction and the other end part is allowed to slidably contact the drain pipe 3.SELECTED DRAWING: Figure 5
【課題】到達立坑を掘削できない場合でも、ドレイン管との間に土砂が入り込むのを防ぎながら、容易に発進立坑側へ引き抜くことができるドレイン管埋設用の二重鞘管を提供すること。【解決手段】地中の横坑２内に設置され、内側に透水性のドレイン管３が配置され、引き抜かれるドレイン管埋設用の二重鞘管７であって、外鞘管８と、外鞘管８内に推進させて設置されるガイド管１０と、ガイド管１０とドレイン管３との間を止水するテールシール１１とを備え、テールシール１１は、筒状であって、ガイド管１０の推進方向の先端部に一端部が取り付けられており、他端部がドレイン管３に摺接可能である。【選択図】図５
