郑东新区水系大跨度控制闸的闸型研究

Research on Huge Span Gate Applied in Water System of Zhengdong New District

介绍了液压上翻转式闸门、组合式液压下翻板闸门和液压下翻转式闸门等新型闸门的布置方案。结合郑东新区实际情况,确定新区CBD如意湖水系与金水河、熊耳河和东风渠段3座控制闸采用闸桥结合液压上翻转闸门,宽度均为104 m,主要由13扇闸门单元、1套底坎埋件、2套主液压泵站、2套电气控制系统和6套锁定液压泵站组成。如意湖出口控制闸推荐气动盾形闸门布置方案。

This ＂article introduces the huge span upward rotation gate and its application. Three sets of gates were applied in Zhengdong New District, and they are located at the cross of Ruyi Lake water system with Jinshni Canal, Xionger Canal and Dongfeng Canal respectively. These three gates were driven by hydraulic cylinder hoist, and the span of the gate was 104 m, and they were constituted with thirteen sets of gate units, one set of sill, two sets of hydraulic power stations, two sets of electrical control system and six sets of locking hydraulic power units. The pneumatic peltate gate was recommended at the outlet of Ruyi Lake.
