Description

Technical Field

[0001] This utility model relates to the field of slope protection technology, specifically to a slope ecological restoration system. Background Technology

[0002] Currently, a common method for slope protection is to use anchors to lay ecological blankets on the slope surface. The three-dimensional structure of the ecological blankets helps maintain soil stability, prevents soil erosion, and provides ecological space for grass seedlings. However, the existing ecological blanket structure is too simple, resulting in poor top resistance and tensile strength. It is only suitable for slopes with flat and stable foundations, and cannot be used for slopes severely weathered with rock erosion, nor for slope reinforcement or steep and complex slopes. Utility Model Content

[0003] To address the aforementioned issues, this application provides a slope ecological restoration system with excellent anti-tipping and tensile strength.

[0004] The purpose of this utility model is achieved through the following technical solution: a slope ecological restoration system, including an ecological restoration blanket fixed on the slope by a fixed structure, wherein the ecological restoration blanket includes several ecological restoration blanket units spliced ​​together in sequence;

[0005] The ecological restoration blanket unit includes a double-twisted hexagonal wire mesh and a soil and water protection blanket covering the double-twisted hexagonal wire mesh; at least one wire in the double-twisted hexagonal wire mesh is a steel rope, and the remaining wires are steel wires.

[0006] Furthermore, when the number of steel wire ropes in the double-twisted hexagonal wire mesh is greater than or equal to two, the spacing between two adjacent steel wire ropes is 400-800mm.

[0007] The left and right edges of the double-twisted hexagonal wire mesh are hinged with connecting wire ropes.

[0010] The fixing structure includes an upper support rope, a lower support rope, and several middle support ropes, all fixed to the slope.

[0011] The upper end of the ecological restoration blanket is folded down to form an upper folded section. The upper folded section is connected to the unfolded part of the ecological restoration blanket by a rope clip. The upper support rope passes through the gap formed between the upper folded section and the unfolded part of the ecological restoration blanket. The lower end of the ecological restoration blanket is folded up to form a lower folded section. The lower folded section is connected to the unfolded part of the ecological restoration blanket by a rope clip. The lower support rope passes through the gap formed between the lower folded section and the unfolded part of the ecological restoration blanket.

[0012] The two adjacent ecological restoration blanket units are overlapped end to end and fixed with rope clips to form an overlapping section; the middle support rope is connected to the overlapping section.

[0013] The width of the overlapping portion is greater than 300mm.

[0014] The soil and water protection blanket is a polyamide monofilament fiber blanket.

Detailed Implementation

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments.

[0027] Example

[0028] like Figure 1 As shown, this embodiment discloses a slope ecological restoration system, which includes an ecological restoration blanket fixed on the slope by a fixing structure; wherein, the ecological restoration blanket includes several ecological restoration blanket units 4 spliced ​​together in sequence. In specific laying, several ecological restoration blanket units 4 can be spliced ​​together in a matrix on the slope according to the specific conditions of the slope, thereby forming an ecological restoration blanket.

[0029] like Figure 5 As shown, the ecological restoration blanket unit 4 includes a double-twisted hexagonal wire mesh 10 and a soil and water protection blanket 11 covering the double-twisted hexagonal wire mesh 10. The soil and water protection blanket 11 is a polyamide monofilament fiber blanket with a porosity of 95%-98% and a thickness greater than 14mm. The double-twisted hexagonal wire mesh 10 is wrapped inside the soil and water protection blanket 11.

[0030] Furthermore, the double-twisted hexagonal wire mesh 10 is a honeycomb mesh woven from multiple sets of two wires in sequence, with hexagonal mesh openings. Its overall shape is the same as that of the traditional double-twisted hexagonal wire mesh. However, the double-twisted hexagonal wire mesh 10 in this embodiment differs from the traditional technology in that, in this embodiment, at least one wire in the mesh woven into the double-twisted hexagonal wire mesh 10 is a steel wire rope 9, and the remaining wires are steel wires 13. If the number of steel wire ropes 9 in the double-twisted hexagonal wire mesh 10 is greater than or equal to two, the spacing between two adjacent steel wire ropes 9 is 400-800mm. In this embodiment, the spacing is set to 500mm. That is, the double-twisted hexagonal wire mesh 10 in this embodiment is woven from a mixture of steel wires 13 and steel wire ropes 9, with the steel wire ropes 9 interspersed among the steel wires 13. During weaving, the steel wire ropes 9 are spaced apart, such as... Figure 5 As shown. The steel wire rope 9 is woven from multiple steel wires, which makes it stronger. By incorporating steel wire rope 9, the strength of the double-twisted hexagonal steel wire mesh 10 can be improved, thereby enhancing the anti-tiring and tensile properties of the ecological restoration blanket.

[0031] In addition, each double-twisted hexagonal wire mesh 10 has connecting steel wire ropes 8 hinged to its left and right edges to enhance the stability of the double-twisted hexagonal wire mesh 10 edges.

[0032] like Figure 6 As shown, the two connecting steel wire ropes 8 on the two adjacent ecological restoration blanket units 4 are connected by a sewing rope 12, thereby connecting the ecological restoration blanket units 4 into a whole.

[0033] In addition, the two adjacent ecological restoration blanket units 4 are overlapped end to end and secured with rope clips to form an overlapping section 6, such as... Figure 3 As shown, this connects the adjacent ecological restoration blanket units 4 into one unit. During actual installation, the upper ecological restoration blanket unit 4 overlaps the lower ecological restoration blanket unit 4, and the overlap width is greater than 300mm, that is, the width of the overlapping part 6 is greater than 300mm. In this embodiment, it is set to 500mm.

[0034] The fixing structure includes an upper support rope 1, a lower support rope 3, and several middle support ropes 2, all fixed to the slope. The upper end of the ecological restoration blanket is folded down to form an upper folded portion 5. This upper folded portion 5 is connected to the unfolded portion of the ecological restoration blanket by rope clips. The upper support rope 1 passes through the gap formed between the upper folded portion 5 and the unfolded portion of the ecological restoration blanket. Figure 2 As shown. The lower end of the ecological restoration blanket is folded upwards to form a lower folded portion 7. The lower folded portion 7 is connected to the unfolded portion of the ecological restoration blanket by a rope clip. The lower support rope 3 passes through the gap formed between the lower folded portion 7 and the unfolded portion of the ecological restoration blanket, as shown. Figure 4 As shown. The central support rope 2 is connected to the overlapping part 6, as... Figure 3 As shown. The widths of the upper folding portion 5 and the lower folding portion 7 are greater than 300mm, but in this embodiment they are set to 500mm.

[0035] During construction, after the ecological restoration blanket is laid on the slope, the two ends of the upper support rope 1 and the lower support rope 3 are fixed to the slope with anchor bolts, and the upper support rope 1 and the lower support rope 3 are pressed tightly against the upper surface of the ecological restoration blanket. Then, the upper end of the ecological restoration blanket is folded over towards its lower end, so that the upper support rope 1 is wrapped between the upper folded part 5 and the unfolded part of the ecological restoration blanket. Next, rope clips are used to fix the upper folded part 5 and the unfolded part of the ecological restoration blanket together. At this point, the ecological restoration blanket and the upper support rope 1 cannot be separated, and the upper end of the ecological restoration blanket is fixed to the slope by the upper support rope 1. The lower end of the ecological restoration blanket is also fixed to the slope by the lower support rope 3 in the same way. The overlap of each pair of adjacent ecological restoration blanket units 4 is fixed to the slope by the middle support rope 2. The support rope and the ecological restoration blanket can be connected by rope clips. When connecting, the rope clip passes through the holes on the soil and water protection blanket 11 and connects the double-twisted hexagonal wire mesh 10 to the support rope. In this way, the support rope and the ecological restoration blanket can be connected.

[0036] In addition, during construction, the ecological restoration blanket can also be fixed with anchor bolts, which press the blanket firmly onto the slope using the anchor plates. Specifically, an anchor bolt can be installed every 2.5m along the slope width and every 5m along the slope height. Furthermore, the connection points between two adjacent ecological restoration blanket units 4 can also be anchored to the slope using several anchor bolts 14, and the overlapping points between two adjacent ecological restoration blanket units 4 can also be fixed to the slope using several anchor bolts.

[0037] It should be noted that all features disclosed in this specification, or all steps in all methods or processes disclosed, may be combined in any way, except for mutually exclusive features and / or steps.

[0038] Furthermore, the specific embodiments described above are exemplary. Those skilled in the art can devise various solutions inspired by the disclosure of this utility model, and these solutions all fall within the scope of this utility model and its protection. Those skilled in the art should understand that this utility model specification and its drawings are illustrative and not intended to limit the scope of the claims.
