电厂取排水工程中钢顶管与钢拉管的选择与应用

Selection and application of the steel jacking pipe and steel drawing pipe in power plant drainage engineering

钢顶管和钢拉管作为常用的非开挖管道的敷设方法,在穿越江堤、河堤的取排水工程中,经常被主管部门强制要求采用。针对这两种方法,从设计计算、施工工艺、工程造价三方面进行了比较,为电厂取排水工程设计施工提供参考。

As the common laying methods of trenchless pipeline,steel jacking pipe and steel drawing pipe are often required to be adopted by the competent authorities in the engineering of taking and draining water across river embankment.In this paper,the two methods are compared from the aspects of design calculation,construction method and cost control so as to provide reference for the design and construction of power plant drainage engineering.
