摘要
工作坑是穿越工程项目的重要内容,基坑支护关系着工程安全、质量、进度。本文依托天津LNG项目输气干线穿越南港铁路实际工程项目,重点介绍了基坑止水、支护加固的施工工艺和方法,对顶管机头进出洞口和在建铁路路基进行加固,保障了工程进程,降低了施工风险。
The work pit is an important part of the project.The pit support is related to the safety,quality and progress of the project.This article relies on Tianjin LNG project gas trunk through the actual project Nangang Railway,focusing on the foundation pit water,support reinforcement of the construction techniques and methods of pipe jacking machine head entrances and exits and reinforcement of railway embankment to protect the project Process,reducing the construction risk.
