钢坝闸在珠海翠屏排洪渠排水防涝中的应用

Application of Steel Dam Gate in Drainage and Waterlogging Prevention ofCuiping Drainage Canal in Zhuhai

翠屏排洪渠是珠海市香洲区几条主要排洪渠之一,其现有滚水坝叠梁闸因过流能力不足,无法达到暴雨期24h排出标准。为提高翠屏渠排洪能力,在滚水坝上游新建钢坝闸并拆除原有滚水坝。钢坝闸可无级调节开度,立门蓄水或防洪,卧门行洪排涝,兼具阻挡外潮与泄洪排涝双重功能。

The Cuiping Flood Drainage Canal is one of the main flood drainage canals in Xiangzhou District,Zhuhai City.The existing rolling dam stacked beam gate cannot meet the 24h discharge standard during heavy rain due to insufficient flow capacity.In order to improve the flood discharge capacity of the Cuiping Canal,a steel dam was built upstream of the rolling dam and the original rolling dam was demolished.The opening of the steel dam gate can be steplessly adjusted,the vertical gate can store water or prevent floods,and the horizontal gate can discharge flood and drain waterlogging.It has the dual functions of blocking external tides and flooding and draining waterlogging.
