Application of Drilling Occlusive Pile with Full Casing in Foundation Pit Engineering for Adjacent Subway in Suzhou

摘要:

以苏州某商业大楼咬合桩的施工为例，介绍全套管钻孔咬合桩在临近地铁基坑支护工程中的应用情况以及咬合桩施工技术要点。施工结果表明，全套管钻孔咬合桩对周围环境影响小，对地层扰动小、施工快、造价低，在苏州软土及高水位土层基坑支护中具有广阔的应用前景。

Abstract:

Taking the construction of an occlusive pile in Suzhou as the example, the paper introduces the application of drilling occlusive pile with full casing in foundation pit support engineering for adjacent subway and the main points of construction technology. The results show that the drilling occlusive pile with full casing has advantages of little influence on environment, small disturbance to the ground, rapid construction and low cost, which has a broad application prospect for foundation pit support engineering in soft soil and high water level ground of Suzhou.
