新型可装卸反滤排水管在水闸工程中的应用

摘要

Filter drainpipe is the key section to water conservancy infrastructure.Based on engineering practice in Da’ao gate dam, a new-designed removable filter drainpipe is easy and simple for disassembling and cleaning, which solves difficult problems of silt.Test results show that the drainpipe can effectively discharge the seepage and reduce the uplift pressure of the project.Mean-while, the new drainpipe is suitable for industrial production, controllable quality, easy maintenance, and more conducive to project management.%反虑排水设施在水利工程中往往是关键部位。大坳拦河闸坝结合工程实际，创新设计了一款便于装卸、清洗的反滤排水管，解决了排水管淤堵的难题。试运行表明，这种排水管能有效排出工程渗流，降低工程扬压力；同时，该新型排水管适合工业化生产，质量可控，维护方便，更有利于工程管理。
