METHOD FOR PREVENTING LIQUEFACTION OF GROUND
PROBLEM TO BE SOLVED: To provide a method for preventing liquefaction in which the peripheral ground is restrained by ground improvement walls when using an existing linear buried object as a utilization state or in the new installation, in the case the peripheral ground of the linear buried object such as an existing or new pipe and drain has a risk of liquefaction.SOLUTION: Ground improvement walls 1a, 1a in the direction of crossing a linear buried object 10 are constructed in parallel in a configuration having a step difference part of a level as a whole, by constructing the part W crossing a portion of the linear buried object to the lower part from a laying position of the linear buried object. Ground improvement walls 1b, 1b in the direction substantially parallel to the linear buried object are constructed in parallel in a position to put the linear buried object and a structure 11 in a lattice spot. Also, a ground improvement wall 1 with a lattice shape in a plan view arriving to the depth being effective for liquefaction prevention of the ground 9 is constructed continuously. A ground protective barrier member 2 forming a groove wall for laying of the linear buried object is provided in a shape of wall at least on the ground of wider region side among the ground 9 divided into two by the linear buried object.SELECTED DRAWING: Figure 2
【課題】既設又は新設の管渠等の線状埋設物の周辺地盤が液状化するおそれがある場合に、既設の線状埋設物を活用状態のまま、又は新設する際に、その周辺地盤を地盤改良壁により拘束して液状化を防止する工法を提供する。【解決手段】線状埋設物１０を横断する方向の地盤改良壁１ａ、１ａを、その一部の線状埋設物を横断する部位Ｗを当該線状埋設物の布設位置よりも下方へ造成することにより、全体として高低の段差部を有する構成で並列に造成し、線状埋設物と略平行する方向の地盤改良壁１ｂ、１ｂを、線状埋設物と構造物１１とを格子目内に納める位置に並列に造成し、かつ地盤９の液状化防止に有効な深さまで到達させた平面視が格子状の地盤改良壁１を連続的に造成する。前記線状埋設物で二分された地盤９のうち、少なくとも広い領域側の地盤に、線状埋設物の布設用溝壁を形成する地盤防護壁部材２を壁状に設ける。【選択図】図２
