Lifting wall-mounted type ecological protection belt for hardening riverway

Abstract

The invention discloses a lifting wall-mounted type ecological protection belt for a hardening riverway. The lifting wall-mounted type ecological protection belt comprises cylindrical steel rails, chains, chain wheels and trapezoid grooves. The cylindrical steel rails are fixed to the shoreside, seams not pulled through are formed in one sides of the cylindrical steel rails. The chains penetrate the hollow parts in the cylindrical steel rails and wind around the chain wheels fixed to the top ends of the cylindrical steel rails. Thin plates are fixed to the two sides of the trapezoid grooves and fixed to the chains through the seams of the cylindrical steel rails. Water outlet holes are formed in the sides, facing the river, of the trapezoid grooves. Arc edges are arranged on the upper edges of the sides, making contact with the river bank, of the trapezoid grooves. Lower layers in the trapezoid grooves are filled with fine filter materials, upper layers in the trapezoid grooves are filled with coarse filter materials, and plants are planted. The lifting wall-mounted type ecological protection belt for the hardening riverway has the technical beneficial effects that the trapezoid grooves can be arranged in a ladder manner along the river bank after being adjusted, and multi-stage processing is carried out on the rainfall runoff; and the construction difficulty is lowered, the construction cost is reduced, and maintenance and management are convenient.

Description

technical field [0001] The invention belongs to the technical field of environmental ecology, and in particular relates to a liftable wall-mounted hardened river channel ecological protection belt. Background technique [0002] The river bank is an important ecological transition area for material, energy, and information exchange between river and terrestrial ecosystems. It has a unique ecosystem structure and service function, and is of great significance to the prevention and control of non-point source pollution. One of the research hotspots in environmental science. However, at present, most rivers in cities are treated with two-sided or even three-sided light, which makes the river lose its ecological function, especially the runoff pollution formed by rainwater directly enters the river from the bank and causes pollution. Although some methods of hanging plants on the river bank are used for the transformation of this hardened river bank, this method will make the co...
