淮水北调西线输水管道工程是目前安徽省最长的大口径输水管道工程,由于管道多座落在重粉质壤土上,地基承载力高,原设计管道基座采用砂垫层,填弧法,改进后,采用粉质壤土填弧,实施中由于地下水位高,无法保证填弧质量,通过试验采用级配碎石填弧,取得较好的效果,保证了工程安全。 West Huai River Water Transfer Project is the longest West Pipeline project in Anhui Province, as the pipe is located in the heavy silt and more loam, the foundation bearing capacity is high, the original design of the pipe base with sand cushion , Arc filling method, improved, the use of silty loam Arc, the implementation of the groundwater level is high, can not guarantee the arc quality, through the test graded gravel arc, and achieved good results, to ensure the safety of the project.
