DRAINAGE PIPE, LIQUEFACTION COUNTERMEASURE CONSTRUCTION METHOD
To provide a drainage pipe that is not easily restricted by the construction site, can suppress a decrease in ground strength at a low construction cost, and can suppress the occurrence of liquefaction, and a drainage pipe thereof.SOLUTION: A drainage pipe 10 provided with a plurality of pipe bodies 11 to 13 having different pipe diameters, which are driven into the ground vertically or diagonally downward from the ground surface and used as a countermeasure against liquefaction of the ground, comprises a first pipe body 11 with the largest pipe diameter, and a second pipe body 12 with the smallest pipe diameter. The inner diameter of the tip of each of the plurality of pipe bodies 11 to 13 is smaller than the inner diameter of the rear end. Each pipe is configured so that it can project freely while locking the rear end to the tip of the outer pipe with a large diameter. At least one or both of the peripheral wall of the first pipe body 11 and the peripheral wall of the second pipe body 12 is a perforated peripheral wall.SELECTED DRAWING: Figure 2
【課題】施工箇所の制約を受け難く、かつ、低施工費で地盤強度の低下を抑制可能な、液状化の発生を抑制することができる排水パイプ、及びその排水パイプを提供する。【解決手段】地盤に地表面から鉛直、若しくは鉛直斜め下方向に打ち込まれて、地盤の液状化対策に用いられる管径の異なる複数の管体１１〜１３を備えた排水パイプ１０において、管径の一番大きな第１管体１１と、管径の一番小さな第２管体１２と、を備え、前記複数の管体１１〜１３を、それぞれ、先端部の内径が後端部の内径より縮径し、各管体を、管径の大きな外側の管体の先端部に後端部を係止させつつ、突出自在に構成し、少なくとも前記第１管体１１と前記第２管体１２の周壁のいずれか一方又は両方を、有孔周壁とする。【選択図】図２
