Sediment-laden river flood discharge gate anti-abrasion structure and operation and maintenance method
The invention relates to an anti-abrasion structure of a silt-laden river flood discharge sluice, the anti-abrasion structure of the silt-laden river flood discharge sluice comprises a sluice chamber, an apron and an anti-abrasion groove which are sequentially arranged in the water flow direction and connected, the sluice chamber comprises a sluice bottom plate and a sluice pier, a plurality of anti-abrasion plates are arranged on the inner side of the sluice bottom plate and the inner side of the sluice pier, and the anti-abrasion plates are fixed together. The apron comprises an apron bottom plate and guide walls, the inclination of the apron bottom plate is the same as the gradient of the natural riverbed, the guide walls are arranged on the two sides of the apron bottom plate, a concrete tetrahedron is arranged on the apron bottom plate, the scour prevention groove is formed by excavating the natural riverbed, and the concrete tetrahedron is placed on the scour prevention groove. When the anti-abrasion structure of the silt-laden river flood discharge gate is used, firstly, the slope of the apron bottom plate is the same as the slope of a natural riverbed, so that the impact force of river water to the apron bottom plate is reduced, the abrasion to the apron bottom plate is reduced, meanwhile, the concrete tetrahedron can also reduce the flow speed of river water on the apron top surface, and the service life of the apron bottom plate is prolonged. The abrasion of river water to the apron is further reduced, and the damage to the apron is reduced.
本发明涉及一种多泥沙河流泄洪闸抗冲磨结构，该多泥沙河流泄洪闸抗冲磨结构包括沿水流方向依次布置且相连的闸室、护坦和防冲槽，闸室包括闸底板和闸墩，闸底板以及闸墩内侧设有多个抗磨板，各抗磨板固定在一起，护坦包括护坦底板、导墙，护坦底板的斜度与天然河床坡度相同，导墙设置在护坦底板的两侧，所述护坦底板上设置有混凝土四面体，防冲槽由天然河床开挖形成，防冲槽上放置有混凝土四面体。本发明的多泥沙河流泄洪闸抗冲磨结构在使用时，首先护坦底板的斜度与天然河床坡度相同，从而减少河水对护坦底板的冲击力，进而降低护坦底板受到的磨损，同时混凝土四面体还能够降低护坦顶面河水流速，进一步降低了河水对护坦的冲磨，减少护坦损坏。
