前言给水管道水压试验是对管道铺设进行最后质量鉴定的手段。对水压试验这项工作的要求主要有两点:一是它应该能够正确地反映管道渗漏情况,二是试压不出问题,就是不要由于试压而使接口遭受损伤,反而影响了工程质量,不要使接口或试压后背遭受破坏,返工重试,造成浪费,更不要出人身安全事故。我们积累了多年的施工经验,基本上能够做到上述两点。但在某些特殊情况下,由于措施不当,也发生过一些问题。这主要由于我们对在水压试验中,管壁、接 Introduction Water pressure test of water supply pipeline is the means of final quality assessment of pipeline laying. There are two main requirements for the hydrostatic test: First, it should be able to correctly reflect the pipeline leakage; second, there should be no problem with the pressure test; that is, the interface should not be damaged due to pressure test; instead, it affects the project. Quality, do not damage the interface or test pressure back, rework to retry, resulting in waste, not to mention personal safety incidents. We have accumulated years of construction experience and can basically accomplish the above two points. However, in some special cases, due to improper measures, some problems have also occurred. This is mainly due to the fact that we
