摘要
引水工程PCCP管道沟槽的地质情况通常比较复杂,而回填质量影响到PCCP管道的运行安全。文中结合坪上应急引水工程PCCP管道沟槽回填的实例,分析了PCCP管道沟槽回填的施工方法。
The geological conditions of the channel in which the PCCP is laid in water diversion project usually are complex.The channel-backfilling quality will impact the operation security of the PCCP.Taking the channel backfilling works of the PCCP in Pingshang Emergency Water Diversion Project as an example,the paper analyzes the concrete construction method to backfill the channel of this kind of pipe.
