Problems solved by technology

Traditional structures such as row structure, riprap structure, spur dam and steel wire mesh stone pocket, etc., although such structures have little impact on the river regime and have a good beach-fixing effect, such structures often use the original wrapping method to isolate and protect the riverbed. Less consideration is given to the material exchange and energy transfer between the river bed and air and water flow, which may have an impact on the ecological environment of the river bottom and the living environment of animals and plants
In addition, this kind of beach protection structure is often fixed on the river bottom by its own weight, and while the consumables and engineering volume are large, there is also a certain degree of instability

Abstract

The invention discloses a water-permeable ecological beach-protecting grille block and a grille group composed of the same. The water-permeable ecological beach-protecting grille block comprises a block body, a through hole is formed in the middle of the block body, water-permeable holes are formed in the side walls of the block body, and the through hole communicates with the water-permeable holes. The water-permeable ecological beach-protecting grille block is simple in structure and convenient to use, by forming the through hole and the water-permeable holes which communicate in the block body, the interior of the through hole is always in a weak circulation state, scouring of a water flow to the beach bottom is avoided, and thus the stability and diversity of an ecological environmentinside a cavity are effectively improved.

Description

technical field [0001] The invention relates to an ecological beach protection grid structure, which belongs to the technical field of beach protection engineering, in particular to a permeable ecological beach protection grid block and a grid group composed of the grid block. Background technique [0002] In the middle and lower waterway improvement projects at the present stage, beach protection and bottom protection are very important parts. The current beach protection structures can be mainly divided into two types: traditional beach protection and ecological beach protection. Traditional structures such as row structure, riprap structure, spur dam and steel wire mesh stone pocket, etc. Although such structures have little impact on the river regime and have good effect of beach consolidation, such structures often use the original wrapping method to isolate and protect the riverbed. Less consideration is given to the material exchange and energy transfer between the ri...
