Ecological revetment combination unit and structure

Abstract

The invention discloses an ecological revetment combination unit and a combination structure, and relates to the technical field of revetment engineering. The ecological revetment combination unit comprises a body, a through groove used for planting revetment vegetation is formed in the body, and the through groove and a slope protection platform where the body is located are obliquely arranged so that the root system of the vegetation in the through groove can grow in the reverse direction of the water flow. The root system of the revetment vegetation grows in the reverse direction of the water flow towards the bank slope through the slope of the through groove, namely the root system grows in the soil of the bank slope along the side opposite to the water flow direction; the bank protection vegetation roots on one side of water flow are few, supporting acting force cannot be provided for the vegetation, and in the flood season or under the impact effect of flood flow, the bank protection vegetation inclines in the water flow direction and is attached to the slope bank; and the hydraulic roughness is remarkably reduced, the flood discharge capacity of a river channel is improved, and meanwhile, the acting force of the water flow on the bank protection vegetation is reduced.

Description

technical field [0001] The invention relates to the technical field of revetment engineering, in particular to an ecological type revetment combined unit and combined structure. Background technique [0002] As we all know, bank revetment is an engineering measure that is artificially processed on the bank slope to prevent wave and water impact erosion and maintain the stability of the shoreline. There are basically three types of bank revetment, engineering revetment, landscape revetment and ecological revetment. Applying for an ecological revetment combination structure is a kind of ecological revetment. [0003] For example, the authorized announcement number is CN107487846B, the authorized announcement date is November 03, 2020, and the invention patent titled "An Ecological Hard Revetment Suitable for Variable Water Level" has a specific structure. The revetment is symmetrically located on both sides of the river, so The revetment is set at a certain slope, including t...

Problems solved by technology

[0004] The disadvantage of the prior art including the above application is that, as is known, most of the ecological bank revetments are planted with vegetation on the bank slope, through the stabilizing effect of the plant root system on the slope bank, the improvement of the habitat of the river slope bank, and the reduction of benthic habitat. The damage of animals to the slope bank can improve the living environment and quality of human settlements, and reduce the cost of river slope bank construction. However, the vegetation on the bank slope will cause high hydraulic roughness, which will affect the flood discharge capacity of the river channel. During the flood season, it is easy to The resistance formed by the vegetation on the bank slope will uproot the plants, causing local instability of the bank slope and local collapse of the bank slope, causing a large number of vegetation to die
