修建地下建筑物,基坑开挖一般采用打桩支护。但因打桩震动及噪音,形成“建设公害”,开始研究采用新型无震动、无噪音的坑壁支护施工法。1954年意大利 ICOS 柱列工法自美传入日本,各建筑厂商不断研究并与外国技术合作,各种“地下墙”的施工方法相继出现。为了降低造价,就考虑使挡土的连续墙有可能代替主体结构壁。而要达到这一目的,连续墙施工法必须满足以下几 Construction of underground buildings, pit excavation generally use piling support. However, due to pile vibration and noise, a “construction hazard” was formed and a new type of vibration-free and noise-free pit wall construction method was adopted. In 1954, the Italian ICOS column method was introduced into Japan from the United States. Various construction companies continuously researched and cooperated with foreign technology. Construction methods of various “underground walls” appeared one after another. In order to reduce the cost, it is considered that the retaining wall may replace the main structural wall. To achieve this goal, the continuous wall construction method must satisfy the following
