红英拦河闸除险加固工程气盾闸设计

Design of pneumatic shield gate in danger control and reinforcement project for Hongying barrage

文章以红英拦河闸除险加固工程为实例,阐述了气盾闸在北方地区的可行性。设计过程中拟定了3种方案进行技术经济比较,并经过过流能力、抗渗稳定、闸室稳定等水力计算,确定气盾闸的布置是合理的。

Taking the danger control and reinforcement project of Hongying barrage as an example, the paper describes the application feasibility of pneumatic shield gate in North area. In the design process, three schemes are drafted and compared in the technical and economic, through these hydraulic calculation of conveyance capacity, anti-seepage stability, lock chamber stability, etc., the layout of the pneumatic shield gate is reasonable.
