摘　　要：在水利工程中,水闸施工是水利施工的重要组成部分,其施工技术直接影响整个水利工程质量。退水闸对应急工况下渠道的闸门调控起到关键作用,要快速完成干渠节制闸的调度过程,必须启用退水闸配合消减水位升幅。退水闸的启用和关闭方式直接影响到南、北长虹渠退水闸渠道退水量、根据规范对南、北长虹渠节制退水阀的设计方案进行计算,同时计算分析施工期与运行期闸室的稳定性。In hydraulic engineering,sluice construction is an important part of water conservancy construction Its construction technology directly affects the quality of the whole hydraulic engineering Exit sluice playsa key role in regulating and controlling sluice in emergency condition In order to complete the main control gate dispatching process quickly,itis necessary touse the back gate to reduce the rise of water level.The opening and closing mode of the exit sluice directly affects the drainage volume of the exit sluice in the south and north Changhong Canal.According to the specification,the design scheme of the controlled water back valve in thesouth and north Changhong Canal is calculatedandthestability ofthegatechamber during construction and operationperiod is calculated and analyzed.
