摘要

摘要: 水利工程中的衬砌结构层经常需要设置即可排水又有防渗功能的排水系统,以解决结构抗浮稳定和水体外渗的技术问题。逆止阀是解决此类问题的新产品,由于目前应用不多,其性能和检测方法尚无规范可依,给工程带来了一定的安全隐患。从工程要求和逆止阀的工作原理出发,提出了止水水头、开启水头和排水流量3个反映逆止阀性能的常用指标;研制了专用的测试设备,并给出其性能指标的测试方法;最后,针对逆止阀的长期性能进行了分析和探讨;研究成果可供逆止阀检测参考。

Abstract: In order to ensure the anti-floating stability of concrete linings and to prevent water infiltration, the drainage system with the function that meets the requirements of both seepage control and drainage is widely needed in water conservancy projects. One of the choices is the reverse check valve. As a new product, the reverse check valve is not widely used, neither its performance nor method is available, which brings a certain risks to projects. The closed head, open head and drainage quantity are put forward based on the engineering requirements and work principles as the common indices for the reverse check valve. The test equipment and method are developed for the reverse check valve. The long-term performance of the reverse check valve is analyzed. The research findings may provide reference for the tests on the reverse check valve.
