混凝土衬砌渠道防渗是提高输水能力,抗冲能力,节水灌溉、节约水资源的有效途径。渠道防渗对地下水的补给减少,对控制沿渠地下水位、防止渠道两边耕地盐碱化均起到了很好的防治作用。只要严格把关混凝土衬砌渠道施工的各个环节,做好施工前和施工后的技术质量要求,现浇混凝土衬砌渠道渗漏问题就可以避免发生,防渗在技术上是可行性的,效果是可见的,节水是显著的。
Seepage prevention of concrete lining channel is an effective way to improve water delivery capacity, impact resistance, water saving irrigation and water conservation. Channel seepage control to reduce the supply of groundwater, to control the water table along the canal, to prevent both the arable land salinization have played a very good role in prevention and treatment. As long as the strict control of all aspects of the construction of concrete lining channels to do a good job before and after construction of the technical quality requirements, leakage of cast-in-place concrete lining canal can avoid the leakage seepage is technically feasible, the effect is visible , Saving water is significant.
