摘　　要：在“厂网河湖岸一体”的长江大保护建设体系中,市政管网施工占据了主要工程量,管道的施工质量决定污水收集率及进厂浓度,因此,新建管网的施工质量在水环境综合治理中尤为重要。根据长江大保护管道施工经验,深入分析HDPE缠绕增强结构壁管施工过程中的各类质量问题及其产生的原因,通过采用管道热熔套+双侧手扳对拉葫芦的优化连接方式、实行管道“五张图”验收机制、严抓过程施工工序、加强施工成品保护等措施,有效解决了HDPE缠绕增强结构壁管的施工质量问题,为后续长江大保护管道施工提供了借鉴。In construction of Yangtze River protection system based on the concept of integration of wastewater treatment plant,pipe network,river,lake and bank protection,the construction of municipal pipe network occupies the main engineering quantity,and the construction quality of network determines the sewage collection rate and sewage concentration entering into the plant.Therefore,the construction quality of newly-built pipeline network is particularly important in the comprehensive treatment of the water environment.Various quality problems and their causes in the construction process of HDPE winding reinforced structural wall pipe were deeply analyzed based on the pipeline construction experience of Yangtze River protection.The construction quality problem of HDPE winding reinforced structure wall pipe was effectively solved by adopting the optimal connection method of pipeline hot melt sleeve and double-side hand spanner to the chain hoist,implementing the pipeline“five drawings”acceptance mechanism,strictly supervising the construction procedure,strengthening the protection of finished products,etc.The results aim to provide reference for subsequent pipe constructions of Yangtze River protection.
