综合管廊立体交叉口管线复合保护施工技术

Construction Technology of Pipeline Composite Protection for Stereo Intersection of Comprehensive Utility Tunnel

在某综合管廊工程中采用钢桁架的方式对电缆进行保护,给水管采用格构柱支撑和混凝土外包梁进行保护,取得较好的效果。确保了施工阶段高压电缆和市政供水的正常运行,工期得到有效控制且工程投资得到大幅降低。

In a comprehensive utility tunnel project,the steel truss is used to protect the cable,and the water supply pipe is protected by lattice column support and concrete outer beam,which obtains good effect. The normal operation of the high-voltage cable construction stage and municipal water supply were ensured,the construction period was under control and the project cost was reduced.
