一柱一桩全自动激光测斜与高精度调垂技术研究

Research on Fully Automatic Laser Inclinometry and High Precision Vertical Adjustment Technology for One Column and One Pile

基于全自动激光测斜与高精度调垂相结合的垂直度控制技术,针对复杂地形下地下空间一柱一桩沉桩技术进行优化,设计了一种钢立柱桩沉桩施工方法,提升了钢立柱桩的平面定位和沉桩垂直度精度。实践表明,该施工工艺成功应用于上海白玉兰广场项目,为地下空间的施工建造带来了良好的社会与经济效益。

Based on the verticality control technology of the combination of fully automatic laser inclinometry and high-precision vertical adjustment,and aiming at the optimization of one column one pile driving technology in underground space under complex terrain,a steel column pile driving construction method is designed,and the plane positioning and pile sinking verticality accuracy of steel column pile are improved.The practice shows that the construction technology is successfully applied to Sinar Mas Plaza project,which brings good social and economic benefits to the construction of underground space.
