PCCP管道输水中套管内安装钢管的施工方法

Talking about the Construction Method for Installing the Steel Pipe in Casing Pipe of PCCP Pipeline System

在完成顶管的套管内安装钢管,是PCCP管道穿越国道、高速、铁路等交叉建筑物的一种有效途径。以大伙房输水二期工程为例,阐述了套管内安装钢管的施工方法,为同类工程项目的施工提供了借鉴。

Installing the steel pipe in the casing pipe after pipe-jacking is an effective way for making PCCP pipe pass through the crossing buildings such as national road,superhighway,and railway,etc.Taking the second phase of Dahuofang Water Conveyance Project as an example,this paper expounds the construction method for installing the steel pipe in casing pipe,which provides the reference for the construction of similar engineering project.
