Description

Technical Field

[0001] The present invention belongs to the technical field of water conservancy projects, and particularly relates to an erosion-resistant ecological slope protection. Background Art

[0002] A water conservancy project is a project built to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating disasters and bringing benefits, and is also called a water project. Water is an essential and precious resource for human production and life, but its natural state does not fully meet the needs of humans. Only by building water conservancy projects can the flow of water be controlled, flood disasters be prevented, and the regulation and distribution of water volume be carried out to meet the needs of people's lives and production for water resources. Water conservancy projects need to build different types of hydraulic structures such as slopes, dams, dikes, spillways, sluice gates, water inlets, channels, aqueducts, raft channels, fishways, etc. to achieve their goals.

[0003] Slope protection is a slope protection technology that combines the basic knowledge of disciplines such as engineering mechanics, soil science, ecology, and botany to support slopes or side slopes, forming a comprehensive slope protection system composed of plants or engineering and plants. It uses the interaction between plants and rocks / soils to protect and reinforce the surface layer of slopes, enabling it to meet the requirements for the stability of the slope surface layer and restore the damaged natural ecology. It is an effective means of slope protection and slope reinforcement. Slope protection can have different shapes according to different requirements.

[0004] Chinese patent document CN219060087U discloses a slope protection for water conservancy projects, including a slope body and a number of protective bricks fixed on the surface of the slope body. Each of the protective bricks is provided with a number of planting grooves for planting protective plants, and each of the protective bricks is provided with a connection mechanism that can connect the protective bricks to each other. The connection mechanism includes connection blocks fixed on the adjacent side walls of the protective bricks and connection grooves provided on the other two side walls of the protective bricks and can cooperate with the connection blocks. Its purpose is to solve the problem that the traditional slope protection bricks are not firmly fixed, and it is easy for ecological vegetation and bricks to slide off after being washed by rainwater in the later stage, damaging the slope protection and losing its protective effect. However, most of the existing slope protection structures use bricks to reinforce the slope protection, with poor water dispersion function, and the anti-erosion and anti-scour effects of the slope protection structure are not good enough. Due to water flow scouring and infiltration, it is easy to cause the loss of turf planting soil on the surface of the slope protection structure, and even cause the collapse of the water conservancy slope protection.

The slope body 1 is arranged on the outside of the river channel, and a concrete foundation 23 is provided at the bottom of the slope body 1, and a wave break wall 24 is provided on the concrete foundation 23. The anti-seepage material layer 2 is laid on the surface of the slope body 1 to prevent the water flow from scouring the soil body of the slope body 1 and reduce the water and soil flow velocity. The slope protection framework 3 is arranged on the anti-seepage material layer 2, and the slope protection framework 3 is fixed on the slope body 1 through the anchor 4 to ensure the joint stability of the slope protection framework 3.

[0024] In the present invention, framework units are arranged on the slope body 1. A number of enclosed areas 5 are formed between adjacent two framework units.

[0028] The splicing structure includes a connecting plug 11 and a connecting slot 12 that match each other. The connecting plug 11 and the connecting slot 12 are respectively arranged on two adjacent slope protection frames 6 up and down. Specifically, a first through hole 13 is provided on the connecting plug 11, and a second through hole 14 communicates with the connecting slot 12.

Each slope protection frame 3 is connected to the fixing frame 18. One end of the fixing anchor rod 17 penetrates through the fixing frame 18 and the anti-seepage material layer 2 and is inserted into the installation hole. The other end of the fixing anchor rod 17 is threadedly connected to the fixing nut 19, and the fixing nut 19 abuts against the fixing frame 18.

The other end of the fixing anchor rod 17 is connected to the fixing nut 19, enhancing the connection strength between the slope protection frame 3 and the slope body 1. By strengthening the fixation of the slope protection frame 3 and the anti-seepage material layer 2, the fixing effect of the slope protection frame 3 and the anti-seepage material layer 2 is improved, and the ability of the slope body 1 to resist water flow impact is increased, which is conducive to preventing soil erosion of the slope body 1. The present invention can effectively reduce the erosion effect of water flow, reduce the scouring force of water flow on the slope body 1, and at the same time, combined with the fixing mechanism 16, make the overall structure of the slope protection more stable and improve the durability of the slope protection.

[0035] In the present invention, frame units are arranged on the slope body 1. A number of enclosed areas 5 are formed between adjacent two frame units. Plants are planted in the enclosed areas 5.

The left and right sides of the upper trapezoidal support part 7 and the lower trapezoidal support part 9 are symmetrically arranged, and the upper trapezoidal support part 7 and the lower trapezoidal support part 9 are symmetrically arranged at the upper and lower ends of the middle connecting part 8. After the slope protection frame 6 is fixed, a regular hexagonal enclosed area 5 is formed between two adjacent slope protection frames 6 on the left and right.

[0038] Among them, the water guiding structure includes water guiding holes 10. Water guiding holes 10 are provided on both the upper trapezoidal support part 7 and the lower trapezoidal support part 9, and the water guiding holes 10 of two adjacent slope protection frames 6 up and down communicate with each other. After two adjacent slope protection frames 6 up and down are spliced, the water guiding hole 10 of the lower trapezoidal support part 9 of the upper slope protection frame 6 communicates with the water guiding hole 10 of the upper trapezoidal support part 7 of the lower slope protection frame 6, so as to introduce the water flow in the upper enclosed area 5 into the lower enclosed area 5 for the water flow to drain smoothly.

[0039] The splicing structure includes a connecting plug 11 and a connecting slot 12 that match each other. The connecting plug 11 and the connecting slot 12 are respectively arranged on two adjacent slope protection frames 6 up and down. Specifically, a first through hole 13 is provided on the connecting plug 11, and a second through hole 14 communicates with the connecting slot 12.
