PIPE SET FOR DRAIN PIPE AND INSTALLATION METHOD OF DRAIN PIPE
PROBLEM TO BE SOLVED: To provide a pipe set for a drain pipe in which the drain pipe reduced in aged deterioration and sediment deposition in the pipe is installed in the underground by giving a proper slope without the need for a pre-process such as the drilling of the natural ground except when the natural ground is harder than a constant degree.SOLUTION: A drain pipe 250 is constituted by serially connecting a top pipe 210 being a metallic egg-shaped tube, a first following pipe 220 and a second following pipe 220, and is pushed in the ground from the slope of the natural ground 20 and installed therein. An upper part of a front end 211 of the top pipe 210 is projected more than a lower part, and the top part with a large egg-shaped sectional curvature radius is directed upward. An interval is provided in the space between contact surfaces in a connecting place of each pipe, and the upper and lower directions are movable mutually.SELECTED DRAWING: Figure 9
【課題】経年劣化と管内の土砂の堆積が少ない水抜き管を、地山が一定の程度以上に固い場合を除いて地山の穿孔等の前工程を必要とすることなく、適切な傾斜を持たせて地中に設置する。【解決手段】金属製の卵形管である先頭パイプ２１０、第１後続パイプ２２０及び第２後続パイプ２２０を直列に連結して水抜き管２５０を構成し、地山２０の法面から地中に押し込んで設置する。先頭パイプ２１０の前端部２１１の上方を下方よりも突出させ、卵形断面の曲率半径が大きい頂部を上方に向ける。各パイプの連結箇所において接触面どうしの間に間隔を設け、上下の向きが相互に可動であるようにする。【選択図】図９
