Embodiment 1

[0049] Such as figure 1 , figure 2 As shown, a protective pad used to prevent soil erosion on a bank slope is woven from warp threads and weft threads that are perpendicular to each other. The protective pad includes a number of regularly arranged structural units.

[0050] Such as figure 1 As shown, each structural unit is a quadrangular pyramid, and the five points A, B, C, D, and E in the figure are the end points of a structural unit. Among them, the plane formed by A, B, C, and D is the bottom surface of the quadrangular pyramid (The bottom surface can be rectangular or square). Point E is the apex of the quadrangular pyramid. Point E is not on the bottom surface of the quadrangular pyramid. In use, point E abuts against the surface of the bank slope as a support, points A, B , C, D are relatively far away from the bank slope surface, and side AB, side BC, side CD, and side DA are used as buffers.

[0051] The side surface of the quadrangular pyramid is woven by warp threads ...

Embodiment 2

[0063] Such as Figure 4 , Figure 4a , Figure 4b As shown, a river ecological bank slope protection system includes a filter pad 10 and a protective pad 9 laid on the river bank slope in sequence, and an anchoring device 8 is used to fix the protective pad 9 and the filter pad 10 on the bank slope.

[0064] Two grooves extending in the horizontal direction are provided on the river bank slope. The groove 7a is located below the lowest water level L and the groove 7b is located above the highest water level H. The upper and lower edges of the filter pad 10 and the protection pad 9 extend into the corresponding The groove is fixed at the bottom of the groove by an anchoring device 8. The distance between two adjacent anchoring devices 8 is 0.8 m to 1.0 m.

[0065] The structure of the protective pad 9 adopts the structure described in embodiment 1, and the structure of the anchoring device 8 is as Figure 5 As shown, it includes: an anchor head embedded in the soil, a bearing plate...

Abstract

The invention discloses a protecting pad for preventing water and soil loss of a bank slope and a protecting system of an ecological bank slope of a riverway. The protecting pad is formed by weaving warps and wefts vertical to each other; the protecting pad comprises a plurality of regularly arranged structural units; each of the structural units is of a rectangular pyramid shape; adjacent structural units are joined through corresponding bottom edges; the pyramid vertex of each structural unit is a supporting part attached to the surface of the bank slope; and the bottom edge of each structural unit is a buffer part relatively far from the surface of the bank slope. The protecting pad for preventing water and soil loss of the bank slope provided by the invention can improve the adhesive ability of vegetation on the surface of the bank slope and prevents the bank slope from water erosion. The engineering durability of the protecting pad can reach more than 50 years.

Description

Technical field [0001] The invention relates to the technical field of river ecological restoration, in particular to a protective mat used to prevent water and soil loss on a bank slope and a river protection system. Background technique [0002] Rainwater runoff caused by rainfall, rivers and lakes waves, and boat waves will erode bank slopes and cause soil erosion, which will have adverse effects on water quality, such as transporting nutrients and pesticide pollutants to water bodies, destroying fish spawning, and harming aquatic life Habitat. [0003] In the prior art, hard erosion control technologies are generally used, for example, concrete blocks, rock mortar masonry surfaces or stone cages to prevent soil erosion. Although these measures can withstand huge hydraulic power, they are usually expensive and not conducive to Ecological restoration and the use of ecological measures to purify water quality. Summary of the invention [0004] The present invention provides a pro...
