非断管法驳接给水管道技术探讨

目前给水支管驳接所采用的方法大部分还是沿用切断既有给水主干管后形成空间,然后重新组装管件形成支管的方法进行。但随着城市政建设的发展,保持连续供水要求越来越高,采用传统的驳接的方法作业停水时间长,管道配件多,成本大,施工复杂。因此寻找一种行之有效的驳接方案是目前给水管线新旧管驳接迫切的任务,为此就非断管法驳接给水新旧管技术应用进行探讨。

On Technology Application of Connecting Feed Water Pipes with Non-broken Tube Method

At present,the method of connecting branch feed water pipes is still to cut off the existing main feed water pipes and then reassemble the pipe fittings to form branch pipes.However,with the development of urban construction, the requirement of sustainable water supply increases rapidly.And the traditional connection method would take a long time to operate with water cut-off,and a lot of pipe fittings are used,with big costs and complex constructions.Thus,to work out an effective scheme of connecting the new and old feed water pipes is an urgent task for us now.This paper tries to make a primary research on the technological application of connecting new and old feed water pipes with the non-broken tube method.
