摘要
上海某公司一3 000t级贮槽罐地基基础采用深层搅拌桩复合地基加固,贮槽罐建成投入使用前发生罐体倾斜,后决定采用压密注浆结合掏土的加固纠偏方案。纠偏施工中结合沉降观测,严格按照纠偏方案执行,使贮槽罐不均匀沉降得到调整,从而达到很好的纠偏效果。
Some 3 000t tank foundation is strengthened with deep mixing pile composite foundation. Before the tank is built completely to begin working, it became inclined. Deviation rectification scheme with compaction grouting and soil excavation is used. During deviation rectification construction, combined with real-time settlement observation, different settlement of tank is adjusted, and good rectification effect is gained.
