取水构筑物是河道水源给水工程的咽喉,其位置及取水型式的选择对其成败影响极大。首先应考虑其安全可靠性:洪水时不会被淹没,枯水时应能保证设计取水量;河床演变时不会被水流冲垮,或因泥沙运动而淤堵;北方河流应注意冰块的堵塞和碰撞;山区河流草情严重,湖泊、水库中藻类及微 The water intake structure is the throat of the river water source water supply project, and the choice of its location and type of water intake has a great influence on its success or failure. First of all, safety and reliability should be considered: floods will not be submerged, and when the water is dry, the amount of water drawn by the design should be guaranteed; when the riverbed evolves, it will not be washed away by water flow, or it will be blocked by silt movement; northern rivers should pay attention to the amount of ice. Blockages and collisions; grass in mountainous rivers is severe, algae and microscopic lakes, reservoirs
