METHOD FOR CONSTRUCTING DEFORMATION SUPPRESSION STRUCTURE, AND METHOD FOR THAWING FROZEN SOIL
To provide a method for constructing a deformation suppression structure that suppresses deformation of surrounding ground when frozen soil thaws, and a method for thawing frozen soil.SOLUTION: A method for constructing a deformation suppression structure 17 that suppresses deformation of surrounding ground when a frozen soil wall 11 formed around a frozen pipe 5 in ground 1 by a freezing method thaws comprises: a boring step of forming a boring hole 13 passing near the frozen pipe 5 in a state where the frozen soil wall 11 is frozen; and an underground structure forming step of filling the boring hole 13 with a cement-based material in a state where the frozen soil wall 11 is frozen to form a cement-based underground structure 15 made of the cement-based material.SELECTED DRAWING: Figure 2
【課題】凍土の融解時における周辺地盤の変状を抑制する変状抑制構造の構築方法及び凍土融解方法を提供する。【解決手段】変状抑制構造の構築方法は、凍結工法により地盤１中の凍結管５の周囲に形成された凍土壁１１の融解時における周辺地盤の変状を抑制する変状抑制構造１７の構築方法であって、凍土壁１１が凍結している状態で、凍結管５の近傍を通過するボーリング孔１３を形成するボーリング工程と、凍土壁１１が凍結している状態で、ボーリング孔１３をセメント系材料で充填しセメント系材料からなるセメント系地中構造体１５を形成する地中構造体形成工程と、を備える。【選択図】図２
