Description

Technical Field

[0001] This utility model relates to the field of slope treatment technology, and in particular to a protective net for preventing soil erosion. Background Technology

[0002] Soil erosion is a long-standing and prominent problem in slope management. Direct impact of rainwater on the soil surface causes splash erosion, dispersing and detaching soil particles. Runoff from surface water further carries soil particles, potentially triggering geological disasters such as slope collapses, posing a serious threat to the ecological environment. Among existing soil protection methods, traditional protective nets often adopt an integrated structural design, which involves directly covering the soil surface with a large area of ​​mesh material and securing it at the edges. However, when the protective net is partially damaged due to external impact, ultraviolet aging, or long-term rainwater erosion, the entire protective net needs to be removed and replaced. This not only increases the labor intensity and maintenance time of workers but also wastes a lot of materials, resulting in high maintenance costs. Utility Model Content

[0003] This utility model relates to a protective net for preventing soil erosion, which solves the problems of high maintenance costs and material waste in traditional integral protective nets that need to be replaced entirely when partially damaged in slope treatment.

[0004] This utility model provides a protective net for preventing soil erosion, specifically including: a laying board, the laying board having a square board structure, the top surface of the laying board having a mating opening penetrating its bottom surface, the mating opening having a square opening structure; a protective net being provided above the laying board, the length of the protective net being consistent with the longitudinal side length of the mating opening; the transverse side length of the mating opening being an integer multiple of the width of the protective net.

[0005] Furthermore, limiting slots are provided on both the left and right sides of the top surface of the laying plate. The limiting slots are in the form of isosceles trapezoidal grooves and penetrate the front and rear surfaces of the laying plate. Countersunk through holes penetrating the bottom surface of the laying plate are provided on both the upper and lower sides of the inner bottom surface of the limiting slot.

[0006] Furthermore, side mating plates are fixedly installed on the left and right ends of the protective net, and limit blocks are fixedly installed on the bottom end of the side mating plates. The limit blocks are in the form of isosceles trapezoidal blocks.

[0007] Furthermore, the side mating plate has a rectangular plate structure, and the length of the side mating plate is consistent with the width of the protective net; the width of the side mating plate is consistent with the distance between the inner end side of the mating opening and the side end face of the adjacent laying plate.

[0008] Furthermore, the limiting block and the limiting slot are slidably inserted into each other; a pull rod is fixedly installed on the top surface of the side mating plate.

[0009] Furthermore, the lateral side length of the mating opening is 6 times the width of the protective net.

[0010] This utility model provides a protective net to prevent soil erosion, which has the following beneficial effects: The continuous planar protective layer formed by the paving board of this utility model can cover the soil surface. Combined with the protective net at the opening, it can directly block the vertical impact of rainwater on the soil, reduce the soil particle shedding caused by raindrop splashing, and at the same time, the mesh structure of the protective net can guide rainwater to infiltrate in an orderly manner, avoid surface water accumulation and strong runoff to erode the soil, and reduce the risk of soil loss.

[0011] This utility model's laying board adopts a square structure, and adjacent boards can be quickly expanded in terms of protection range by fitting their edges together. The protective net is fixed by sliding insertion of limiting blocks and limiting slots. Workers can complete the installation with the help of a pull rod, without the need for complicated tools, which greatly shortens the construction cycle. It is especially suitable for rapid deployment in large-area protection areas. Moreover, the protective net adopts an independent modular design, and a single set of protective nets can be disassembled and replaced individually. When a local protective net is damaged due to impact, aging, etc., it is not necessary to disassemble the entire laying board or replace all the protective nets. The damaged parts can be replaced simply by pulling out the pull rod, which reduces the difficulty of operation and maintenance time, reduces material waste, and significantly reduces the later maintenance costs.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Example: Please refer to Figures 1 to 4 : This utility model proposes a protective net to prevent soil erosion, comprising: a laying board 1, which is square in shape, with a mating opening 103 extending through its bottom surface on the top surface of the laying board 1; a protective net 2 above the laying board 1, the length of which is the same as the longitudinal side length of the mating opening 103, and the lateral side length of the mating opening 103 being an integer multiple of the width of the protective net 2, specifically, the lateral side length of the mating opening 103 being 6 times the width of the protective net 2; limiting slots 101 are provided on both the left and right sides of the top surface of the laying board 1, the limiting slots 101 being isosceles trapezoidal grooves, and the limiting slots 101 extending through the front and rear surfaces of the laying board 1; countersunk through holes 102 extending through the bottom surface of the inner end of the limiting slots 101 are provided on both the upper and lower sides of the bottom surface of the inner end of the limiting slots 101.

[0017] The protective net 2 has a side mating plate 201 fixedly installed on its left and right ends. A limiting block 203 is fixedly installed on the bottom end of the side mating plate 201. The limiting block 203 has an isosceles trapezoidal block structure. The side mating plate 201 has a rectangular plate structure. The length of the side mating plate 201 is consistent with the width of the protective net 2. The width of the side mating plate 201 is consistent with the distance between the inner side of the mating opening 103 and the side end of the adjacent laying plate 1. The limiting block 203 is slidably inserted into the limiting slot 101. A pull rod 202 is fixedly installed on the top end of the side mating plate 201.

[0018] The working principle of this embodiment: When the protective operation is started, multiple sets of laying boards 1 need to be laid flat on the soil surface to be protected in sequence according to the outline of the soil protection area. The laying boards 1 adopt a square board structure. Adjacent laying boards 1 can be joined by the edges to form a continuous planar protective layer. Its coverage can be flexibly adjusted according to the actual scour risk area. To ensure that the paving slab 1 does not shift under the influence of external environment such as rain and wind, workers can pass fasteners such as bolts and ground nails through the countersunk through-hole 102 and screw them into the soil below. The countersunk design allows the top of the fastener to be flush with the bottom surface of the limiting slot 101, thus avoiding obstruction to the installation of subsequent components. The mating opening 103 on the top surface of each set of laying boards 1 is the core area of ​​soil protection. The mating opening 103 directly corresponds to the soil to be protected below. The length of the protective net 2 is consistent with the longitudinal side length of the mating opening 103. The transverse side length of the mating opening 103 is 6 times the width of the protective net 2. Therefore, the mating opening 103 can be completely covered by splicing six sets of protective nets 2 on a single laying board 1. When installing the protective net 2, the limiting blocks 203 at the bottom of the side fitting plates 201 at both ends of the protective net 2 are slidably inserted into the limiting slots 101 of the laying plate 1 to achieve fixation. Both the limiting slots 101 and the limiting blocks 203 adopt an isosceles trapezoidal structure. This structure has the advantages of strong guidance and is not easy to loosen after insertion, which can effectively prevent the protective net 2 from shifting laterally when under force. At the same time, the width of the side fitting plates 201 is perfectly matched with the distance from the inner side of the fitting opening 103 to the side end of the adjacent laying plate 1, ensuring that the side fitting plates 201 can fit tightly against the surface of the laying plate 1 after insertion, avoiding gaps. The workers only need to grasp the pull rod 202 at the top of the side fitting plates 201 and insert the limiting blocks 203 into the front or rear opening of the limiting slots 101 to quickly complete the installation of a single set of protective net 2. After installing six sets of protective nets 2 in sequence, the edges of each set of protective nets 2 are connected to each other to form a complete mesh protective layer covering the opening 103. This protective layer can not only block the direct impact of rainwater on the soil and reduce the soil particles falling off due to raindrop splashing, but also allow rainwater to infiltrate in an orderly manner through the mesh structure, avoiding the surface runoff caused by water accumulation from eroding the soil, while not affecting the permeability of the soil surface. During long-term use, the protective net 2 may be partially damaged due to external impact, aging and other factors. Since the protective net 2 adopts a modular design and each set of protective net 2 is independently connected to the laying plate 1, when a set of protective net 2 is damaged, the staff does not need to disassemble the entire laying plate 1 or replace all the protective nets 2. They only need to pull the limiting block 203 of the damaged protective net 2 out of the limiting slot 101 through the pull rod 202 to complete the disassembly of a single protective net 2. When replacing the new protective net 2, the above plug-in installation steps can be repeated to restore the protective function of the area. This modular maintenance method not only reduces the difficulty of operation for staff and reduces maintenance time, but also avoids the material waste caused by the need to replace the whole protective net due to partial damage in traditional integrated protective nets. It significantly reduces the later maintenance cost and extends the service life of the entire protective system.
