为满足排水需要,乌鲁木齐市需在河滩路铺设一条DN1 800的污水管道。然而,河滩路是乌鲁木齐市的一条重要交通干道,地质特殊且部分路段有立交桥等障碍,故不适宜采用常规管道施工工艺。经综合考虑管道施工技术及经济等各方面的因素,确定采用顶管施工技术。该工程已正常运行7年,未出现任何异常情况。详细介绍了该工程的施工方法和要点,并分析了顶管穿越河滩路难点、土层加固处理措施和施工注意事项,可供相关工程参考借鉴。
In order to meet drainage needs, Urumqi needs to set up a DN1 800 sewer line at Hetan Road. However, Hetan Road is an important traffic artery in Urumqi. Due to the special geological conditions and the overpass of some sections, it is not suitable to adopt the conventional pipeline construction technology. After comprehensive consideration of pipeline construction technology and economy and other factors, to determine the use of pipe jacking construction technology. The project has been operating normally for 7 years without any abnormalities. The construction methods and key points of the project are introduced in detail. The difficulties of pipe jacking through river beach are analyzed. The reinforcement measures and construction precautions are also provided. It can be used as a reference for related projects.
