摘　　要：常规的球墨铸铁管道安装施工中,一般采用起重机吊管入沟,再用倒链进行管道安装,这种施工方法存在效率低、工期长、成本高的缺点。威海市河库水系连通工程施工中采用大功率挖掘机吊装、安装一次性管道施工工艺,具有效率高、成本低、质量高的特点,既能保证施工质量,又能提效降费。In the conventional installation and construction of nodular cast iron pipe,the crane is generally used to lift the pipe into the ditch,and then the pipe installation is carried out by the inverted chain.This construction method has the disadvantages of low efficiency,long construction period and high cost.The use of high-power excavator hoisting and installing disposable pipe construction technology in the construction of water connection among rivers and reservoirs project,has the characteristics of high efficiency,high quality and low cost,which can not only ensure the construction quality,but also improve efficiency and reduce costs.
