閘門用于調(diào)節(jié)上下游水位和流量

2022-3-4
閘門是水工建筑物的重要組成部分之一,它可以根據(jù)需要封閉建筑物的孔口,也可全部或局部開啟孔口,用于調(diào)節(jié)上下游水位和流量,從而獲得防洪、灌溉、供水、發(fā)電、通航、過木過筏等效益,還可用于排除漂浮物、泥沙、冰塊等,或者為相關(guān)建筑物和設(shè)備的檢修提供了必要條件。

Gate is one of the important components of hydraulic structures. It can close the orifice of the building according to the need, or open all or part of the orifice to regulate the water level and flow of upstream and downstream, so as to obtain the benefits of flood control, irrigation, water supply, power generation, navigation, rafting, etc. It can also be used to remove floating matter, sediment, ice, etc., or to inspect relevant buildings and equipment. The repairs provided the necessary conditions. Gates are usually located in the main throat of intake and outlet of intake and conveyance structures. They can play their functions and benefits and maintain the safety of buildings by opening and closing them flexibly and reliably. For example, in some water intake and water supply projects, control gates are generally set up to regulate the flow rate according to the need; in the intake of pumping stations and the intake and outlet of some tunnels, culverts, inverted siphons, etc., maintenance gates are generally set up to provide conditions for the maintenance of hydraulic structures and pumping equipment; and in reservoir overflow dams or spillways, flood discharge work gates are generally set up. It is used to control the water level of the reservoir and flood discharge downstream to maximize the functional benefits of the reservoir.
