Ecological sinking bed for slow-flow river restoration

Abstract

The invention provides an ecological sinking bed for slow flow river restoration. The ecological sinking bed is of a right triangle structure, and the hypotenuse of the ecological sinking bed is located on one side of the river bank of a river and arranged along the river bank; a first right-angle side of the ecological sinking bed is arranged at the upstream of the river, and a preset angle is formed between the first right-angle side and the river bank; and a second right-angle side of the ecological sinking bed is arranged at the downstream of the river. According to the invention, the ecological sinking bed is designed into a right triangle shape, the hypotenuse is fixed to one side of the river bank, the first right-angle side is arranged at the upstream of the river and forms a preset angle with the river bank, river water on the upstream face plays a role in drainage, water flow is guided to the river channel main groove, and therefore impact of the water flow on the sinking bedcan be reduced, the sinking bed structure is kept stable, and scouring of the river water to the river bank is relieved; and the second right-angle side is arranged at the downstream of the river toform a slow flow or a still water area, so that the aquatic organisms can find food, rest and avoid risks, and the ecological sinking bed can induce water flow to be in a bent form to promote formation of a zigzag form of river deep pool-shoal staggering.

Description

technical field [0001] The invention relates to the technical field of ecological restoration of water quality purification rivers, in particular to an ecological sedimentation bed used for restoration of slow-flowing rivers. Background technique [0002] Small and medium rivers are generally located in the middle and upper reaches of large rivers, with clean sources and clean water. However, with the increase of population and the intensification of agricultural non-point source pollution, the water quality of more and more small and medium-sized rivers is deteriorating day by day, and the water ecosystem is damaged. In addition, the traditional governance model of small and medium-sized rivers focuses on the waterlogging and flood discharge functions of the river, dredging the river and building hard bank revetments, while ignoring the restoration of the natural ecosystem of the river. [0003] In water purification technology, compared with physical and chemical methods,...

Problems solved by technology

[0006] In view of this, the present invention proposes an ecological sedimentation bed for the restoration of slow-flowing rivers, aiming to solve the problem that the impact force of the water flow in the existing river channel is relatively large and the water flow will wash and erode the river bank and limit the use of artificial sedimentation beds
