针对渠道外地下水位较高,非灌溉输水期渠道内外水位差较大,渠道边坡容易产生失稳、滑坡的问题,文章以实际例子阐述了应用逆止阀有效解决这类问题的具体方法。通过10多年的运行表明,逆止阀在沙河段渠堤防渗工程中的应用是成功的,达到了预期的效果,功能符合设计要求。既解决了渠道渗水的问题,又能有效防止非灌溉输水期因渠内外渗透压力差大、堤身土含水量大导致堤身失稳滑坡的发生。
In view of the fact that the water level outside the channel is relatively high, the water level difference between the inside and outside of the channel during non-irrigated water transfer period is large, and the slope of the channel is prone to instability and landslide, the article expounds the concrete method for effectively solving such problems by using the check valve . After more than 10 years of operation, it has been proved that the application of the check valve in the seepage control project of the Shahe canal dyke is successful and has achieved the expected effect. The function conforms to the design requirements. Not only solve the problem of water seepage channel, but also effectively prevent the non-irrigated water due to the difference between the inside and outside the seepage pressure is large, dike soil moisture led to the occurrence of landslide instability.
