Water ecological restoration device of hard revetment riverway

Abstract

The invention provides a water ecological restoration device of a hard revetment riverway. The water ecological restoration device comprises the hard revetment riverway, supporting rods, fixed rods, transverse rods, planting baskets, movable screws and expansion screws, wherein the supporting rods, the fixed rods and the transverse rods are connected through the movable screw to form triangular supporting frames; each fixed rod is provided with a drilling hole; the expansion screws are used for fixing the fixed rods at one side of the hard revetment riverway through the drilling holes; each supporting rod is provided with a T-shaped clamping groove; T-shaped clamping strips are arranged on the planting baskets; the T-shaped clamping strips are connected with the supporting rods through theT-shaped clamping grooves; the plurality of planting baskets are arranged and are distributed on the supporting rods in a ladder shape. According to the water ecological restoration device provided by the invention, the supporting frames for planting water plants are constructed so that the problem that the hard revetment riverway is lack of a water plant-attaching medium can be solved; emergentaquatic plants, floating-leaf water plants and submerged plants are planted at different water depth positions according to an ecological theory and a natural distribution law of the water plants so that the aim of constructing an artificial channel aquatic ecosystem can be rapidly realized.

Description

technical field [0001] The invention relates to a water ecological restoration device for a hard revetment river course, which belongs to the field of river water ecological restoration, in particular to the field of urban artificial river water ecological restoration. Background technique [0002] For a long time, people have paid more attention to the flood discharge and drainage capacity of river channels, river bed scour, and water and soil conservation issues. The treatment of urban rivers is often limited by these factors and artificial channelization is carried out, resulting in a single cross-section of the river and a straight direction. Most of the river slope protection is gravity-type mortar stone retaining wall and reinforced concrete retaining wall structure. These artificial rivers meet the needs of flood drainage, but have caused many ecological crises. On the one hand, hard revetment rivers often have relatively simple habitats and lack suitable places for a...

Problems solved by technology

This scheme can improve the ornamental value of artificial rivers to a certain extent, but relying on terrestrial plants or wet plants to purify water quality, the purification effect is not ideal

Laying floating beds, ecological filter dams, and planting submerged plants in the river can greatly imp...
