PAY-OUT TYPE DRAINAGE PIPE, GROUND DRAINAGE STRUCTURE, AND METHOD OF PENETRATING PAY-OUT TYPE DRAINAGE PIPE
To provide a pay-out type drainage pipe that has low penetration resistance and can be constructed with a small device without pre-boring, and can penetrate into deep underground by preventing the inflow of sediment even if it penetrates into the ground while applying vibration, and a ground drainage structure, and a method of penetrating a pay-out type drainage pipe.SOLUTION: A pay-out type drainage pipe 1 which comprises a plurality of pipe bodies (outer pipe 2, inner pipe 3) having different pipe diameters, in which another pipe body (inner pipe 3) can be accommodated in the outer pipe 2 having the largest pipe diameter among these plurality of pipe bodies, and which is penetrated into ground G having a slope or a vertical surface comprises a fitting portion in which the plurality of pipe bodies (outer pipe 2, inner pipe 3) are fitted to each other when the pipe bodies are stretched. A large number of drainage holes are provided in the inner pipe 3 having the smallest pipe diameter among the plurality of pipe bodies (outer pipe 2, inner pipe 3), and an inflow prevention material 5 for preventing the inflow of sediment from the drainage hole is provided inside the inner pipe 3.SELECTED DRAWING: Figure 6
【課題】プレボーリングを行わなくても貫入抵抗が小さく小型の装置で施工が可能であり、振動をかけつつ地盤に貫入させても土砂の流入を防止して地下深くまで貫入可能な繰出し式排水パイプ、地盤排水構造、及び繰出し式排水パイプの貫入方法を提供する。【解決手段】管径の異なる複数の管体（外管２、内管３）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（内管３）が収納可能な斜面又は鉛直面を有する地盤Ｇに貫入される繰出し式排水パイプ１において、複数の管体（外管２、内管３）を、延伸したときに互いの管体（外管２、内管３）が嵌合する嵌合部を備え、複数の管体（外管２、内管３）のうち一番管径の小さな内管３に、多数の排水孔を設けるとともに、内管３の内側には、排水孔からの土砂の流入を防止する流入防止材５を設ける。【選択図】図６
