摘要
针对当前基坑支护中存在的问题,开发出一种新的基坑支护桩——矩形沉管干提土式咬合灌注连续桩。理论计算及应用表明该桩型能降低基坑支护造价15%~25%。沉管干提土工艺施工能彻底摒弃泥浆污染,降低挤土对周边桩和环境的影响。
Aiming at the problems existing in the current support, a new kind of foundation pit supporting pile-rectangular immersed tube dry soil type bite perfusion piling arises at the historic moment. Through theoretical calculation and application, which can reduce the cost of foundation pit supporting pile type about 15% to 25%; Engineering practice has proved, immersed tube dry soil technique can completely abandon the mud pollution, reduce the effects of compaction of surrounding pile and the environment.
