摘要:
结合南京市九乡河闸站工程深基坑中“坑中坑”支护的工程实例,介绍了利用高压旋喷桩替代深层搅拌桩成墙的改进型SMW 工法对基坑的支护,同时在水利工程中首次利用支护墙体作相关处理后替代建筑物混凝土临土侧模板。工程实践表明,该方法避免了建筑物基础周边的土方开挖与回填,有效防止因回填土体的沉降而引起土方与混凝土接触面的脱空,以较低的成本在工程质量和施工进度方面取得了较好的效果,给类似工程的基坑支护提供了新的思路和技术参考。
Abstract:
Combined with the project of“pit in pit”support in deep foundation pit of Jiuxiang River Gate Station in Nanjing City, the improved SMW construction method which replaced deep mixing pile by high pressure jet grouting pile was introduced. Meanwhile, the building concrete soil side template is replaced with the supporting wall for related treatment in the water conservancy project for the first time.The engineering practice showed that this method could avoid earth excavation and backfilling around the building base, effectively prevent subsidence caused by backfill earthwork and concrete contact surface void, and achieve good results in engineering quality and construction progress with low cost,which could provide new ideas and technical reference for similar foundation pit support engineering.
