兰州市污水管网工程中顶管施工技术应用与探讨

摘要

Pipe jacking is a trenchless technique of underground pipeline construction. In the municipal engineering construction, the pipe jacking technology can effectively reduce the impact of construction on buildings and roads near the city and the pipe network itself. A detailed description of the pipe jacking construction in Lanzhou is introduced and its complex geological conditions are discussed. Results can be used as reference for similar projects.%结合兰州市污水处理厂14#路段污水管网工程,对黄土地质条件下项管推力进行了计算,并进一步从施工方案选择、施工工艺、流程以及顶管施工减阻、纠偏和测量控制等方面对顶管施工技术进行了较全面的论述.所述施工技术方案适用于兰州地区工程地质属于卵石层、透水性强、地下水丰富、地下水和河床水互补的实际情况,可供今后同类型工程参考.
