目前,一般工业与民用建筑的室内排水管道,大多采用缸瓦管、PVC 硬塑料管及铸铁管等。因施工质量不佳或用户使用不当,管道破裂、漏洞等现象时有发生,重新更换管道势必会增加维修费用,而且对排水系统的正常使用影响较大,给用户带来许多不便。我们在工程实践中摸索到一些简单、实用的维修方 At present, most of the indoor drainage pipes for general industrial and civil buildings use cylinder tiles, PVC hard plastic pipes, and cast iron pipes. Due to poor construction quality or improper use of users, pipeline ruptures and loopholes occur from time to time. Re-replacement of pipes will inevitably increase maintenance costs, and will have a greater impact on the normal use of drainage systems, causing many inconveniences to users. We have found some simple and practical repairs in our engineering practice.
