Description

Technical Field

[0001] The utility model belongs to the technical field of slope protection, and in particular relates to a water conservancy slope protection net. Background Art

[0002] In the construction of water conservancy projects, there are many common slope protection forms, mainly including stone slope protection, concrete slope protection and plant slope protection. Among them, stone slope protection and concrete slope protection have been widely used due to their unique structural characteristics and functional advantages. These hard slope protection forms have simple and clear structures, which are not only naturally beautiful, but also have excellent impact resistance and erosion resistance. Therefore, in large-scale water conservancy projects, especially in areas that need to withstand long-term water flow erosion, these slope protection forms have been widely adopted. However, stone slope protection mainly uses the interlocking effect between stones to resist the erosion of water flow. When the impact of water flow is large, the stones will be subjected to the thrust and scouring force of the water flow, which may easily lead to slope collapse or stone falling off. Secondly, concrete slope protection has high strength and durability, which can effectively resist the scouring and erosion of water flow. However, when the impact of water flow is large, concrete slope protection may crack or break. Therefore, the utility model specially designs a water conservancy slope protection net, which is intended to be applied to key parts of hard slope protection such as stone slope protection and concrete slope protection that are frequently subjected to water flow impact, to achieve effective protection of the surface of these hard slope protections, thereby ensuring that their stability and safety are significantly improved, while effectively extending their service life.

[0003] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The utility model is applied to the key parts of hard slope protection such as stone slope protection and concrete slope protection that are frequently subjected to water flow impact, aiming to solve the problem of reduced life of slope protection due to frequent water flow impact, realize effective protection of slope protection against water flow impact, and extend its service life. The protective net of the utility model is composed of a mesh structure of the surface mesh layer and the inner mesh layer. This structural design not only ensures excellent water permeability, but also can effectively disperse external force impact. A buffer layer of sponge material is provided inside the protective net. When the water flow impacts the protective net, the sponge material can quickly exert its excellent buffering effect, effectively reduce the impact force, and quickly absorb moisture in the water flow. This water absorption mechanism not only helps to reduce the impact, but also as the sponge expands after absorbing water, its thickness increases, thereby providing a stronger buffering capacity during the next water flow impact.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Example

[0017] See also Figure 1-2 The utility model provides the following technical solutions: a water conservancy slope protection net, the structure of which includes a protection net and a fixed cone 1. The protection net is composed of a surface net layer 2, a buffer layer 3 and an inner net layer 4. The hierarchical structure between the three is clear, forming an effective protection system. The buffer layer 3 is cleverly placed between the surface net layer 2 and the inner net layer 4 to provide additional buffer protection; the surface net layer 2 and the inner net layer 4 both adopt a mesh structure, which not only has excellent water permeability, but also can effectively disperse external force impact and improve the overall impact resistance. In order to enhance the stability of the protection net, crimping parts 5 are installed at the mesh structure nodes of the surface net layer 2 and the inner net layer 4; the crimping parts 5 are composed of a first buckle 6 and a second buckle 7, and perforations 8 are provided at the center of the first buckle 6 and the second buckle 7. These perforations 8 are adapted to the size of the fixing cone 1, so that the fixing cone 1 can smoothly pass through the perforations 8 and firmly fix the protection net on the slope; the first buckle 6 and the second buckle 7 are respectively installed on both sides of the surface net layer 2, the buffer layer 3 and the inner net layer 4, and connected by crimping. This connection method not only ensures the stability of the protection net, but also improves the convenience of installation, making the entire slope protection net system more stable and reliable.

[0018] In order to ensure the edge strength of the perforation 8 and facilitate the connection of the two buckles, in this embodiment, as a preferred technical solution of the utility model, a crimping portion 9 is provided at the center of the first buckle 6, and the perforation 8 is opened at the center of the crimping portion 9. The crimping portion 9 of the first buckle 6 simultaneously penetrates the nodes of the surface mesh layer 2 and the inner mesh layer 4 and the surface of the buffer layer 3, and the first buckle 6 and the second buckle 7 are fixedly connected by crimping through the crimping portion 9.

[0019] In order to facilitate the clamping of the surface mesh layer 2, the buffer layer 3 and the inner mesh layer 4 of the protective net, in this embodiment, as a preferred technical solution of the utility model, the edge of the second buckle 7 is evenly provided with clamping teeth 10, and the clamping teeth 10 are evenly distributed around the edge of the second buckle 7.

[0020] In order to ensure the buffering performance and improve the buffering performance by means of a water absorption mechanism when subjected to water impact, in this embodiment, as a preferred technical solution of the utility model, the buffer layer 3 is made of a water-absorbing sponge material and has a thickness of 5-10 mm.

[0021] In order to, in this embodiment, as a preferred technical solution of the utility model, the first buckle 6 and the second buckle 7 are both integrally formed structures, and the first buckle 6 and the second buckle 7 are both made of metal.

[0022] In summary, with the help of the above technical solution of the utility model, in the case of water flow impact, the water flow will directly act on the surface of the protective net. Both the surface mesh layer 2 and the inner mesh layer 4 adopt a mesh structure, which not only has excellent water permeability, but also can effectively disperse external force impact and improve the overall impact resistance. Since a sponge buffer layer 3 is set inside the protective net, when the water flow impacts the protective net, the sponge can effectively reduce the impact force and quickly absorb the moisture in the water flow, thereby increasing the thickness of the sponge buffer layer 3. This water absorption mechanism enables the protective net to further improve its buffering capacity with the help of the sponge buffer layer 3 that has absorbed and expanded water when the water flow impacts the next time.

[0023] In addition, the first buckle 6 and the second buckle 7 in the crimping member 5 play a key role in the crimping fixation process. They can tightly combine the surface mesh layer 2 of the protective net, the nodes of the buffer layer 3 and the buffer layer 3 itself, and effectively prevent the separation of the various components. At the same time, through the uniform fixation of the fixing cone 1, the protective net can be firmly attached to the slope, thereby avoiding falling due to water absorption by the sponge buffer layer 3.
