摘要
PROBLEM TO BE SOLVED: To provide a fluidization countermeasure structure and a fluidization countermeasure construction method of a pipeline buried in the ground requiring no special burying material or support pile, and capable of reducing fluidizing pressure acting on a pipe when fluidization of the ground is caused.;SOLUTION: A wedge-like member is arranged on a fluidization upstream side side surface of the pipe buried in the ground anticipated to be fluidized. The pipe attached with a flexible bag body is buried in the ground anticipated to be fluidized, a solidifying fluid is fitted in the bag body, and the bag body is formed in a wedge shape. Thus, when the fluidization is caused, side fluid pressure applied to the pipe is reduced. Since a burying material sufficiently enters around under the pipe in a process of burying the pipe, a pipeline foundation is stabilized.;COPYRIGHT: (C)2002,JPO
