摘　　要：渠道防渗逆止阀的单向排水功能,可以让地下水流进渠道内从而释放压力,能够防止渠道内的水渗入地下。根据地下水位高的渠道容易受到浮动破坏的实际需求,将渠道防渗逆止阀应用于已建和新建具有潜在地下水破坏的混凝土防渗衬砌渠道,一方面可以保证原有衬砌渠道的防渗性能不受任何影响,另一方面可以单向有效排除地下水,防止地下水位过高导致混凝土防渗衬砌渠道产生浮动破坏或滑坡,具有良好的经济效益、环境效益和社会效益,推广应用前景广阔。The one-way drainage function of the anti-seepage check valve in canals allows groundwater to flow into the canal,thereby relieving pressure and preventing canal water from seeping into the ground.To address the actual need for canals with high groundwater levels that are prone to flotation damage,anti-seepage check valves have been applied to both existing and newly constructed concrete-lined canals that are at risk of groundwater damage.This application ensures that the original anti-seepage performance of the lined canals is not compromised while effectively allowing one-way drainage of groundwater.This prevents high groundwater levels from causing flotation damage or landslides in the concrete-lined canals.The solution offers significant economic,environmental,and social benefits and has broad prospects for widespread application.
