清江口提水泵站取水口管道工程顶管施工技术研究

Research on Pipe Jacking Construction Technology of Intake Pipeline Project of Qingjiangkou Water Pumping Station

清江口提水泵站取水口位于长江北岸黄广大堤外滩,受长江水位以及复杂地质、地形、公共设施、建筑物等因素影响,选用泥水平衡顶管掘进机施工。在施工中,对顶管施工设备选择、顶管施工平台布置、顶管施工技术方案等进行了研究。实践证明,应用该技术施工,较好地解决了工程质量、进度、投资、安全等关键问题,且社会和经济效益较为明显,可供同类型工程的施工参考借鉴。

Qingjiangkou water pumping station intake is located in Huangguangdadi Bund on the north bank of the Yangtze River,affected by the water level of the Yangtze River and the complex geology,topography,utilities,buildings and other factors,is constructed by mud-water balance pipe jacking machine.In the construction,selection of pipe jacking construction equipment,pipe jacking construction platform layout,pipe jacking construction technology program are studied.It has proved that the application of this construction technology is a better solution to the project quality,progress,investment,safety and other key issues,and brings social and economic.It can be used as a reference for the construction of the same type of project.
