摘　　要：顶管技术近年来在我国发展迅猛,特别是在穿越江堤或不便拆除建筑物的地下排水渠施工中,优点更加明显。江苏省桥林水厂综合取水工程,通过采用泥水平衡式顶管技术,实现了不用开挖就能引水管接连桥林综合取水泵房的设想。重点介绍了大口径顶管施工工艺技术参数、泥水平衡式顶管工艺的基本原理和工艺流程。与开挖施工技术相比,采用顶管施工工艺大大降低了征借地、青苗补偿等费用,从而节省了工程投资。可为同类施工提供参考。Pipe jacking technology has been developing rapidly in recent years,especially in the construction of underground drains that cross river banks or inconvenient to remove buildings,and the advantages of pipe jacking technology are more obvious.The comprehensive water intake project of Qiaolin water plant in Jiangsu province used mud-water balanced pipe jacking technology,which has realized the idea of connecting the diversion pipe to Qiaolin comprehensive water intake pump house without excavation.This paper focuses on the technical parameters of large diameter pipe jacking construction process,the basic principle of mud and water balance pipe jacking process,and process flow.This paper focuses on the technical parameters of large diameter pipe jacking construction process,the basic principle of the mud and water balance pipe jacking process,and process flow.Compared with the excavation construction technology,the use of pipe jacking construction process greatly reduces the cost of land acquisition and borrowing,seedling compensation,etc.,thus saving the project investment.It can provide a reference for similar construction.
