硬聚氯乙烯塑料排水管在住宅工程中的应用

近年来,我国一直十分重视新型管材的开发和应用,禁止或限制某些金属管材的使用,新型管材的应用越来越广。在推广使用的管材中,主要为各种塑料管材。但由于有些新型管材暂无设计及施工验收的国家规范,使用中容易出现各种问题,本人根据在施工中的体会,总结硬聚氯乙烯塑料排水管特点以及在施工中应注意的几个问题。

Application of UPVC plastic drainpipe in residence engineering

In recent years,the development and application of new tubular products are paid more attention in China.Some metal tubular products have already been prohibited or restrict,in contrast,the application of new tubular products becomes wider and wider.The main tubular products,that promoted are different kinds of plastic tubular products.However,because there are still no relevant national norms about the design and construction acceptance for some new tubular products,it is easy to come out various problems use.Combined with personal experience about construction, this essay mainly focuses on the specialty of UPVC plastic drainpipe and several problems that need to be noticed during the process of construction.
