摘要
以哈尔滨地铁1号线太平桥站为例,对地铁车站深基坑距离条形基础建筑物仅有0.75m的保护施工进行了重点研究,在实施过程中通过采取"下延式钢管导墙"、刚性接头及小幅段单爪成墙等手段,以及设置隔离桩、注浆、墙缝探挖、加强支撑和监测等综合施工措施,有效地保护了邻近建筑物的安全。
Taking Taipingqiao Station of Harbin Subway Line 1 for example, this paper made research on the protection construction that the distance is only 0.75m between strip foundation building and deep excavation in metro station. In the process of implementation, by taking guide wall of decurrent steel pipe, rigid joint and single grapple construction unit to a wall, and setting isolation to digging pile, grouting, wall joints explore digging, strengthen support and surveillance and other comprehensive construction measures, the safety of adjacent buildings was effectively protected.
