[0030] In order 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 in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.
[0031] Example 1
[0032] like Figure 1 , 2 As shown, this embodiment discloses a slope reinforcement ecological restoration blanket, which includes a three-dimensional ecological blanket 1 and a reinforcement net 2; wherein the three-dimensional ecological blanket 1 is coated on the outside of the reinforcement net 2, so that the three-dimensional ecological blanket 1 and the reinforcement net 2 form an integrated structure.
[0033] In specific implementation, the reinforcement net 2 adopts a double-twisted hexagonal wire net. By combining the three-dimensional ecological blanket 1 and the double-twisted hexagonal wire net into an integrated structure, the strength of the slope reinforcement ecological restoration blanket can be enhanced.
[0034] As another implementation method, the slope reinforcement ecological restoration blanket also includes a plurality of steel wire ropes 3 twisted together with the reinforcement net 2, such as Figure 3 As shown. In specific implementation, the steel wire rope 3 is twisted with the reinforcement net 2, and then the three-dimensional ecological blanket 1 covers the two, so that the three-dimensional ecological blanket 1, the reinforcement net 2 and the steel wire rope 3 are combined into one. In specific settings, the distribution of the steel wire rope 3 on the reinforcement net 2 can be longitudinally spaced, transversely spaced, or cross-distributed, which can be set according to the specific situation.
[0035] The slope reinforcement ecological restoration blanket in this embodiment combines the three-dimensional ecological blanket 1, the reinforcement net 2 and the steel wire rope 3 into one, which can further enhance the strength of the slope reinforcement ecological restoration blanket, so that the slope reinforcement ecological restoration blanket can meet the needs of ecological restoration and slope reinforcement at the same time.
[0036] Example 2
[0037] This embodiment discloses a slope reinforcement ecological restoration system, which includes at least two end support ropes 8, a plurality of fixing members 5 and a plurality of slope reinforcement ecological restoration blankets in the above-mentioned embodiment 1.
[0038] The slope reinforcement ecological restoration blankets are spliced together to form an integrated, larger area restoration blanket structure. Specifically, two adjacent slope reinforcement ecological restoration blankets are connected and fixed by a connector 6, which can be a rope clip, such as Figure 4 As shown, or the connecting member 6 can be a suture rope, such as Figure 5 shown.
[0039] In addition, two end support ropes 8 can be provided, and the two end support ropes 8 are respectively fixed at the opposite ends of the repair blanket structure. For example, the two end support ropes 8 can be respectively fixed at the upper and lower ends of the repair blanket structure, or the two end support ropes 8 can be fixed at the left and right ends of the repair blanket structure; in this embodiment, the two end support ropes 8 are respectively fixed at the upper and lower ends of the repair blanket structure, and the two end support ropes 8 are fixed to the fixing member 5, such as Figure 1 When the fixing member 5 is fixed on the slope, the entire repair blanket structure can be fixed and covered on the slope surface through the two end support ropes 8.
[0040] In specific implementation, Figure 6 As shown, the fixing member 5 is an anchor rod, wherein the anchor rod can be implemented by a chicken head core ring anchor rod or an anchor pad anchor rod.
[0041] In order to make the two end support ropes 8 better fix the repair blanket structure, as Figure 7 As shown, the opposite ends of the repair blanket structure are folded toward the center thereof, so that folded portions 7 are formed at the opposite ends of the repair blanket structure, and the folded portions 7 are connected and fixed to the unfolded portion of the repair blanket structure through a connector 6, and the end support ropes 8 pass through the cavity formed between the folded portions 7 and the repair blanket structure, so that the two end support ropes 8 can be fixed to the repair blanket structure. Similarly, the connector 6 used here can also be a rope clip or a suture rope.
[0042] As another implementation method, the slope reinforcement ecological restoration system also includes a plurality of intermediate support ropes 4, which are arranged at intervals on the upper surface of the repair blanket structure and are located between the two end support ropes 8. The intermediate support ropes 4 are also fixed by the fixing member 5 to press the middle part of the repair blanket structure against the slope surface. Similarly, the intermediate support ropes 4 can also be arranged at intervals longitudinally, or at intervals transversely, or cross-distributed. In this embodiment, the arrangement direction of the intermediate support ropes 4 is set to be consistent with the arrangement direction of the two end support ropes 8.
[0043] The construction method of the above-mentioned slope reinforcement ecological restoration system is as follows:
[0044] First, according to the area of the slope, several slope reinforcement ecological restoration blankets are spliced together and laid on the surface of the slope to form a restoration blanket structure on the slope surface. The area of the restoration blanket structure matches the area of the slope and at least covers the entire area of the slope.
[0045] When splicing the slope reinforcement ecological restoration blanket, two steel wire ropes 3 on the edges of two adjacent slope reinforcement ecological restoration blankets close to each other are connected and fixed by a connector 6, such as Figure 4 Or 5. Because the three-dimensional ecological blanket 1 is a multi-layer mesh structure, even if the wire rope 3 and the fixed net 2 are wrapped inside the three-dimensional ecological blanket 1, the two wire ropes 3 can be connected and fixed by the connecting piece 6, and they will not be affected by the three-dimensional ecological blanket 1.
[0046] Next, two end support ropes 8 are laid on the upper surfaces of the upper and lower ends of the repair blanket structure, and four fixing members 5 are respectively fixed on the slope positions corresponding to the ends of the two end support ropes 8, and the two ends of the two end support ropes 8 are respectively fixed by two fixing members 5, so that the two end support ropes 8 press the upper and lower ends of the repair blanket structure. When fixing, the ends of the end support ropes 8 are passed through the heart-shaped holes on the fixing members 5 and then folded back, and then the folded back part and the unfolded part of the end support ropes 8 are fixed by the connecting members 6.
[0047] Then, the upper and lower ends of the repair blanket structure are folded toward the center thereof, thereby forming folded portions 7 at opposite ends of the repair blanket structure, and the steel wire rope 3 on the folded portion 7 is connected and fixed to the steel wire rope 3 on the unfolded portion of the repair blanket structure by a connector 6. At this time, the end support rope 8 is wrapped between the folded portion 7 and the repair blanket structure. Figure 7 At this time, the two end support ropes 8, the repair blanket structure and the fixing member 5 are connected together, and the repair blanket structure is fixed on the slope surface.
[0048] As required, multiple fixings 5 may be installed at intervals at the side slope positions corresponding to the middle part of the end support rope 8, and the middle part of the end support rope 8 may also be connected to the fixings 5, so that the end support rope 8 can be more stable. When the middle part of the end support rope 8 needs to be connected to the fixings 5, the fixings 5 of this part need to be first passed through the end support rope 8, and then the fixings 5 at both ends of the end support rope 8 are fixed.
[0049] Finally, multiple intermediate support ropes 4 are arranged at intervals on the upper surface of the repair blanket structure. The arrangement direction of the intermediate support ropes 4 is consistent with the arrangement direction of the end support ropes 8, and they are located between the two end support ropes 8. After the intermediate support ropes 4 are arranged, multiple fixing members 5 are installed at intervals at both ends of the intermediate support ropes 4 and at the corresponding slope positions in the middle. The intermediate support ropes 4 are fixed to the fixing members 5 so that the intermediate support ropes 4 press the middle part of the repair blanket structure against the slope surface. The fixing method between the intermediate support ropes 4 and the fixing members 5 is the same as the fixing method between the end support ropes 8 and the fixing members 5.
[0050] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.
