Lake-entering estuary trash holding device and construction method
The invention relates to the technical field of water pollution prevention and control, and discloses a lake-entering estuary trash holding device and a construction method.The lake-entering estuary trash holding device comprises ecological walls and wall dams, the ecological walls extend towards the two sides of a riverway estuary in the lake embankment direction, a channel is formed between the ecological walls and the lake embankment, and the wall dams are arranged in the channel; the heights of the multiple wall dams are gradually increased in the water flow direction, the heights of the ecological walls are not smaller than the heights of the wall dams, and the adjacent wall dams, the ecological walls and the lake embankment enclose to form a sedimentation tank. The ecological walls can distribute water flow output by the river mouth into the channels on the two sides, so that the water outlet speed of the river is slowed down, and the water outlet direction of the river is changed; the wall dam in the channel can intercept and filter pollutants such as silt in the river layer by layer, so that the pollutants in the river channel are prevented from being discharged to the lake, disordered deposition of the silt entering the lake is reduced, and the silt deposited in the sedimentation tank is convenient for subsequent desilting; when the river drainage is higher than the designed water level, the water flow overflows the ecological wall top, and the high-water-level drainage of the river is not affected.
本发明涉及水污染防治技术领域，公开了一种入湖河口拦污装置及施工方法，入湖河口拦污装置包括生态墙和墙坝，生态墙向河道河口两侧顺湖泊堤岸方向延伸，生态墙与湖泊堤岸间形成通道，若干墙坝设置在通道中，若干墙坝的高度沿水流方向递增，生态墙高度不小于墙坝高度，相邻墙坝与生态墙和湖泊堤岸间围合成沉淀池，本发明中生态墙可将河道河口输出的水流分流向两侧的通道中，减缓了河流出水速度，改变了河流出水的方向，通道中的墙坝可将河流中的泥沙等污染物层层拦截过滤，从而减少河道中污染物排向湖泊，并减少了进入湖泊泥沙的无序沉积，沉积在沉淀池的泥沙便于后续清淤；当河道排水高于设计水位时，水流会漫过生态墙顶，不影响河道高水位排水。
