摘要
为保障封开县南丰镇经济社会安全发展,封开县相关管理部门拟在南丰镇贺江侧建设排涝闸,以降低贺江洪水对南丰镇居民生活的影响,达到兴利除害的目的。排涝闸施工是水利工程项目施工的重点,也是工程质量和影响整个工程施工进度的关键因素。南丰镇防洪工程排涝闸拟建在贺江与内河交汇处,两岸房屋密集,施工期导流流量大、水位高,且排涝闸河床地层为强透水层,施工条件有限,施工难度大。根据水工建筑物的布置形式,结合地质、水文、施工工期、施工道路等因素,介绍了封开县南丰镇防洪工程内、外河交汇处的排涝泵闸的施工导流设计,以供类似工程参考。
In order to ensure the economic and social security development of Nanfeng Town,Fengkai County,the relevant management department of Fengkai County plans to build a floodgate on the side of Hejiang River in Nanfeng Town,so as to reduce the impact of floods on the Hejiang River on the lives of residents in Nanfeng Town,and achieve the purpose of promoting benefit and eliminating harm.The construction of the drainage gate is the key point of the construction of the water conservancy project,and it is also the key factor affecting the quality of the project and the construction progress of the whole project.The flood gate of Nanfeng Town Flood Control Project is planned to be built at the junction of the Hejiang River and the inland river.There are dense houses on both banks.During the construction period,the diversion flow is large and the water level is high.In addition,the riverbed stratum of the flood gate is a strong permeable layer,so the construction conditions are limited and the construction is difficult.According to the layout of hydraulic structures,combined with factors such as geology,hydrology,construction period,construction roads,etc.This paper introduces the construction diversion design of the drainage pump gate at the intersection of the inner and outer rivers of the flood control project in Nanfeng Town,Fengkai County,so as to provide reference for similar projects.
