摘　　要：严寒环境下排水管道施工问题一直是困扰施工单位和建设单位的一大难题。作者在长期的施工和设计工作中,总结出以下严寒环境下排水管线施工方法,即管道的防腐、焊接、检查井井盖等重点施工项目集中保护处理;管沟开挖、回填及管道闭水试验快速处理;检查井及检查井进出水管制作及连接特殊处理的方法,从而保证整个工程施工质量合格,并且节省工程费用,保障施工单位和建设单位的经济利益不受损失。The construction of drainage pipeline in freezing cold environment is a big difficult problem always perplexing the construction units. Through long-term construction and design work, several cold environment drainage pipeline construc- tion methods were summed up, namely centralized protective treatment of anti-corrosion, welding of the pipe, manhole lid of drainage well and other key construction projects; pipe ditch excavation, backfilling and processing of pipeline water quick test; production of drainage well and inlet and outlet pipe and special treatment of connecting points. It is aimed to guarantee construction quality, and to save project cost.
