Kind Code:
B2
Abstract:
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
