An ecological sedimentation bed for slow-flow river restoration

Abstract

The invention provides an ecological sedimentation bed used for the restoration of slow-flowing rivers. The ecological sedimentation bed is a right-angled triangle structure, and the hypotenuse is arranged on one side of the bank of the river and along the river bank; the first right-angled side of the ecological sedimentation bed is arranged on At the upstream of the river, the first right-angle side is set at a preset angle with the river bank; the second right-angle side of the ecological sedimentation bed is set at the downstream of the river. In the present invention, the ecological sinking bed is designed as a right-angled triangle shape, and the hypotenuse is fixed on one side of the river bank. Leading to the main channel of the river, so as to reduce the impact of water flow on the sedimentation bed, maintain the stability of the sedimentation bed structure and slow down the erosion of the river bank by the river; the second right-angle side is set at the downstream of the river to form a slow flow or still water area, which is beneficial to aquatic life. Biological foraging, resting and avoiding danger, this ecological sedimentation bed can induce the water flow to take a curved form, and promote the formation of a meandering form of deep pools and shoals in the river.

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
