莲江口灌区位于黑龙江省汤原县境内,属高寒地区。灌区建筑物受冻害破坏严重。为解决这个问题,笔者在1989年新安节制闸的设计中,改革了传统式水工建筑物设计方法,采取了方箱式与桩、板式两级消能的结构型式。实践证明效果良好。具有以下优点: 一、消能效果好水流是在叠加梁式闸门板上部溢流,属薄壁堰流。方箱式消力池的侧墙与下游原设计河底齐平,整个消力池埋于河底以下,水流跌入池中后,由于三侧池的墙作用,在池中形成环状旋涡水流,消杀跌落水流的功能,余能再由消力板以底能消流方法消杀。从而达到消能目 Lianjiangkou Irrigation District is located in Tangyuan County, Heilongjiang Province, is an alpine region. Irrigation district buildings damaged by the damage. In order to solve this problem, in the design of Xin’an control gate in 1989, the author has reformed the design method of traditional hydraulic structures and adopted the structure type of energy dissipation with square box and pile and plate. Practice has proved effective. Has the following advantages: First, the energy dissipation effect of water flow in the superposed beam gate plate overflow, is a thin wall weir flow. The side wall of the square box-type stilling pool is flush with the original river bottom of the downstream design. The entire stilling pool is buried below the river bottom. After the water falls into the pool, due to the wall function of the three side pools, a circular vortex is formed in the pool Water, kill the function of falling water, I can then by the end of the anti-consumer board can eliminate the flow method. So as to achieve energy dissipation
