洪潮江水闸闸线选择及水工建筑物布置

Selection of Sluice Line and Layout of Hydraulic Structures of Hongchao River Sluice

洪潮江水闸由于年久失修,水毁严重,造成闸室上部结构垮塌,基础被淘空,下游河床形成多处冲坑,重建工程的方案通过对闸址地形地貌、地质、水文、枢纽建筑物布置、对外交通、征地拆迁、施工、工程投资等条件的分析论证,选择在原闸址上重建。确定的水闸枢纽布局,采用16孔×10m露顶式平底闸方案。工程建成后运行效果良好。笔者对洪潮江水闸闸线选择及水工建筑物布置进行详细介绍。

Due to the disrepair of Hongchao River sluice and serious flooding damage, the upper structure of the sluice chamber collapsed, the foundation was washed out, and many scouring pits were found in the downstream river bed. Through the analysis and demonstration of the landform of the sluice site, geology, hydrology, layout of key buildings, external transport, expropriation and removing, construction, project investment, the original sluice site is selected for reconstruction. The layout of the sluice junction is determined, and a 16-hole×10m open-top flat-bottom sluice scheme is adopted. The project works well after completion. The selection of sluice line and layout of hydraulic structures of Hongchao River sluice are introduced in detail.
