水利设施是保障沿河居民生产安全的重要工程,在水库上建设的堤坝,河道两侧的护坡大多为土质结构,一旦遭遇大水,长期受到水侵的堤坝便会出现管涌现象。管涌发生时,如不及时处理,空洞会在很短的时间内扩大,其势不可挡,从而导致堤坝坍塌。文章对管涌机理进行了深入分析探讨,研究了管涌封填装置的机理,并对比了几种不同封填装置的应用,对管涌现象的快速补救有着重要的意义。
Water conservancy facilities are an important project to ensure the safety of residents along the river. Dam structures built on the reservoirs are mostly used for soil structures. In the event of floods, long-term floodwaters will cause pipe-flooding. When a pipe burst occurs, if it is not dealt with in time, the void will expand in a very short period of time and it will be unstoppable, resulting in the collapse of the embankment. The paper conducts an in-depth analysis and discussion on the piping mechanism, studies the mechanism of the pipe filling device and compares the application of several different sealing devices, which is of great significance to the quick recovery of the piping phenomenon.
