摘要:以深圳市前海综合交通枢纽及上盖物业工程为依托,针对该工程深基坑紧邻地铁线路、周边环境复杂、地质条件特殊等情况,为保证地下连续墙施工不影响紧邻地铁线路正常运营,选择成槽机+旋挖机+冲孔方锤进行地下连续墙入岩成槽施工。通过采取施工质量控制措施,避免施工振动过大,降低施工与维护成本,达到良好的施工效果。

Abstract: Based on the Shenzhen Qianhai Comprehensive Transportation Hub and Upper Cover project,in view of the deep foundation excavation of the project is adjacent to the subway lines,the surrounding environment is complex,and the geological conditions are special,in order to ensure that the construction of the underground continuous wall does not affect the normal operation of the adjacent subway lines,the trenching machine,rotary excavator and punching square hammer were selected to construct the underground continuous wall into the rock. By taking construction quality control measures,it can avoid excessive construction vibration, reduce construction and maintenance costs, and achieve good construction effect.
Keywords: subways; deep foundation excavation; underground continuous walls; construction
