Embodiment Construction
[0018] Technical thinking of the present invention is:
[0019] Build a permeable diversion and ecological restoration system, including permeable guide piers, permeable spurs, and permeable diversion wall devices. When the river water enters the lake swing, it first passes through the permeable diversion piers to divert the flow. Part of the water is directly purified by the permeable diversion piers and then enters the lake swings, and the other part bypasses the permeable diversion piers and enters the lake swings to promote water exchange in the lake swings and increase The hydraulic retention time of the water body in the river can effectively improve the water quality. Secondly, through the setting of permeable spurs on both sides of the lake bank, the sedimentation in the river will be promoted, and the flow rate of the sinking lake water body will be reduced, which is conducive to the formation of diverse biological habitats. Thirdly, the water body is diverted throug...
