Stereoscopic net structure member for ecological bank protection

Abstract

The invention provides a stereoscopic net structure member for ecological bank protection. The stereoscopic net structure member for ecological bank protection is characterized by an outer component of a box structure, a cross-shaped component is arranged inside the outer component, and the four ends of the cross-shaped component make contact with the corresponding inner walls of the outer component; the outer walls of the four corners of the outer component are sequentially provided with a first protruding part, a second protruding part, a third protruding part and a fourth protruding part which are used for being clamped to adjacent outer components; and through holes perpendicular to the axis of the outer component are formed in the walls of the outer component and wing plates of the cross-shaped component. The stereoscopic net structure member for ecological bank protection effectively reduces the flow velocity of water on a nearshore bank slope and relieves wave energy, thereby preventing nutrient soil on the bank slope from being eroded by the water.

Description

technical field [0001] The invention belongs to the field of river regulation engineering, and in particular relates to a three-dimensional network structural member for ecological bank protection. Background technique [0002] Since the 1950s, many western countries have reflected on the practice of destroying the natural environment of rivers, and are gradually transforming rivers back to nature. Since the 1990s, Germany, the United States, Japan, France, Switzerland, Austria and other countries have demolished the hard materials previously artificially laid on the riverbed on a large scale. In fact, the capital investment of removing the lining is much more expensive than that of laying the lining, but these countries generally believe that maintaining the natural environment of the river is extremely important for protecting animal and plant resources, protecting water quality, and preventing water loss. Constructing ecological embankments and restoring riverside plant ...

Problems solved by technology

However, there are also problems with the semi-ecological revetment structure. The main manifestations are: the structural design only considers the plane grid structure, and the energy dissipation effect and soil conservation effect of the plane grid structure in the water level fluctuation area are poor. After the project is completed, after a flood period, the water level changes. The nutrient soil and vegetation seeds in the area are basically eroded, affecting the ecological effect

[0004] "An Ecological Revetment Component" (Application No. 2013204745692) adopts a frame structure surface, which sets through holes and realizes the engagement of adjacent components through protrusions and depressions. However, the engagement of adjacent components may easily cause the occlusion of the through holes. Weaken the revetment effect

[0005] "An Ecological Revetment Prefabricated Component" (application number 2015204447052) also uses protrusions and depressions to form a revetment structure, but the surface of the frame parts is provided with through holes, and there is no gap between the frame parts, so the revetment effect is not good.
