现代化城市市政综合管廊工程施工

综合管廊是现代化城市建设发展的重要市政工程。该文以某城市新区管廊工程为例,依据施工概况对管廊施工的重点难点问题进行分析,针对性地提出管廊基坑开挖工艺,钢板桩放坡喷锚支护、放坡土钉墙支护、钢板桩支护等基坑边坡支护方法,以及管廊工程的防排水工程。该文旨在为类似工程施工的优化设计提供参考。

Comprehensive pipe corridors are important municipal projects for the construction and development of modern cities.This paper takes the pipe gallery project in a new urban area as an example,analyzes the key and difficult issues in the construction of the pipe gallery based on the construction overview,and proposes the foundation pit excavation technology of the pipe gallery,steel sheet pile slope shotcrete and anchor support,slope soil nail wall support,steel sheet pile support and other foundation pit slope support methods,as well as the water prevention and drainage works of the pipe gallery project.This paper aims to provide reference for the optimization design of similar projects.
