摘要
天津地铁5号线幸福公园站在基坑围护结构地下连续墙施工中遇到了1条不能切改的110k V电缆,该电缆沿纵向贯穿基坑,阻碍了地下连续墙的施工。通过采取对电缆箱体的保护、变更导墙设计、重新划分地下连续墙槽段等一系列技术措施,采用反循环成槽工艺,破解了施工中遇到的难题,顺利完成了该槽段施工。
During the construction of diaphragm wall in Xingfu Park Station in Tianjin Subway line 5, this paper encountered a cable with llOkV voltage which can＇ t be cut off or changed. It runs through the foundation excavation longitudinally, and hindered the construction of diaphragm wall. Engineering and technical personnel take a series of technical measures, including the protection for cable box, change the design of the guide wall, redrawing the groove section of diaphragm wall, using reverse circulation crafts to construct, which solves some problems encountered in the construction, and successfully completes the construction of the section.
