土地整治项目中的输排水工程设计

输排水工程是土地整治项目中的重要内容。该文以南昌县向塘镇高田村土地整治项目为例,探讨了农田水利给排水工程方案的设计。通过对沟渠流量计算及纵横断面设计结果表明:设计灌水率是确定渠道设计流量的依据,排涝模数是确定排水沟设计流量的重要依据,而沟渠设计流量是确定纵横断面的主要依据。因此,在输排水工程中,合理确定设计灌水率及排涝模数尤为重要。

Design of Delivery and Drainage Engineering in Land Consolidation Project

Water delivery and drainage engineering was main content in land consolidation project.With land consolidation project in Gaotian Village,Xiangtang Town,Nanchang County as an example,the design of farmland water conservancy drainage project was discussed.Through canal flow calculation and longitudinal and cross section design,the results showed that,designing irrigation rate is the basis for determining canal flow,the flood drainage modulus is grounded on the drainage modulus,longitudinal and cross section are based on canal flow design.Therefore,it was vital for determining reasonable irrigation rate and drainage modulus in water transfer and drainage project.
