GROUND LIQUEFACTION PREVENTION METHOD
PROBLEM TO BE SOLVED: To provide a ground liquefaction prevention method that enhances earthquake-proof safety of an above-ground structure when a ground with an existing or new culvert and other linear buried objects could liquefy, by constructing a ground improvement wall of a closed continuous grid form when seen in a planar view, across the existing or new sewage pipe and others continuously and surrounding an underground area of the above-ground structure.SOLUTION: A ground improvement wall in a direction across a groove for installing a linear buried object 2 has an opening 3 formed to divide a range of a certain height between a portion directly below and a portion directly above 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が埋設された地盤が液状化する虞がある場合に、平面視が格子形状に閉じて連続する地盤改良壁を、既設又は新設の下水管等を横断して連続状態に、且つ「地上構造物」の地下を取り囲む配置に造成して、前記地上構造物の耐震安全性を高める、地盤の液状化防止工法を提供する。【解決手段】線状埋設物２の布設用溝を横断する方向の地盤改良壁は、同線状埋設物の直下部と直上部の間に一定高さ範囲を分断させた構成で開口３を形成する。【選択図】図２
