Description

Technical Field

[0001] This utility model relates to the field of gabion mesh, specifically a gabion mesh with adjustable mesh aperture. Background Technology

[0002] As a flexible support structure, the technological development of gabion mesh has been guided by both material iteration and functional upgrades. The production process has also evolved from hand weaving to standardized mechanical weaving. The product forms cover a variety of types such as gabion boxes and Reno mattresses. The corresponding specifications need to be selected according to the specific engineering scenario. Special scenarios require customization of larger or smaller apertures. Therefore, a gabion mesh with adjustable mesh aperture is needed.

[0003] Existing gabion meshes have fixed mesh sizes during production. If the mesh size needs to be adjusted to suit different needs in a project, the original gabion mesh must be completely removed and replaced with a new product of the new specifications. Without a special anti-erosion coating, under long-term water flow, the sand and gravel particles carried by the high-speed water flow will continuously impact the mesh surface. Over time, this will wear down the galvanized or alloy layer on the mesh surface, exposing the mesh to the water. This can lead to mesh deformation, localized breakage, and an inability to support the weight of the soil or stones, resulting in the collapse of the protective structure. Therefore, there is an urgent need for a gabion mesh with adjustable mesh sizes. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a gabion mesh with adjustable mesh size to solve the problem that when using existing gabion meshes with adjustable mesh size, the mesh size is fixed in the production process. If the mesh size needs to be adjusted in an engineering scenario to adapt to different needs, the original gabion mesh needs to be completely removed and replaced with a new specification product. The surface does not have a special anti-erosion coating design. Under long-term water flow erosion, the sand and gravel particles carried by the high-speed water flow will continuously impact the surface of the mesh wire. Over time, this will wear down the galvanized layer or alloy layer on the surface of the mesh wire, exposing the mesh wire to the water. The gabion mesh is prone to mesh deformation and local breakage, and cannot bear the weight of the soil or stones, leading to the collapse of the protective structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gabion mesh with adjustable mesh size, comprising a gabion mesh body, wherein a first connecting strip is welded to both sides of the gabion mesh body, an adjusting rod is installed on the inner wall of the first connecting strip, a second connecting strip is fixedly connected to one end of the adjusting rod, and a locking block is welded to the outer wall of the second connecting strip.

[0006] The outer walls of the second connecting strip are all welded with gabion mesh, and the outer walls of the gabion mesh are coated with a wear-resistant ceramic coating.

[0007] Preferably, the gabion mesh body is arranged parallel to the first connecting strip, and the first connecting strip is arranged symmetrically about the central axis of the gabion mesh body.

[0008] Preferably, the first connecting strip is movably connected to the adjusting rod, and the inner wall of the first connecting strip has a slotted design.

[0009] Preferably, the adjusting rod is threadedly connected to the second connecting strip, and the inner wall of the second connecting strip is threaded.

[0010] Preferably, the locking block engages with the first connecting strip, and the locking blocks are evenly spaced on the inner wall of the first connecting strip.

[0011] Preferably, the outer wall of the gabion subnet is tightly fitted to the inner wall of the wear-resistant ceramic coating, and the outer wall diameter of the gabion subnet is smaller than the inner wall diameter of the wear-resistant ceramic coating.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model features a gabion mesh main body woven from alloy steel wire, with pre-reserved welding areas at its edges to match the first connecting strip, ensuring connection strength. Both the first and second connecting strips are made of flat steel, with galvanized surfaces to enhance corrosion resistance. They are welded to the wire edges of the gabion mesh main body using carbon dioxide gas shielded welding. The second connecting strip is connected to the gabion sub-mesh using the same welding process. The adjusting rod is made of threaded steel, with precise external threads machined on its surface, and is movably connected to the end of the first connecting strip. The other end of the adjusting rod precisely matches the pre-set internal threaded hole at the end of the second connecting strip, forming a stable threaded connection. The interlocking of the two is achieved through thread engagement. The gabion sub-mesh is identical in material and initial mesh size to the gabion mesh main body, and is set parallel to one side of the gabion mesh main body. Its edges are fixed to the second connecting strip by welding, forming... The main and secondary mesh structures corresponding to the main gabion mesh are initially aligned with the mesh of the main gabion mesh. At this time, the overall mesh size maintains the initial specifications to ensure basic protection. During adjustment, the operator can directly use a wrench to rotate the adjustment rod, which will convert the rotational motion into the linear motion of the second connecting bar. The mesh of the secondary gabion mesh gradually changes from complete alignment to partial overlap with the mesh of the main gabion mesh. The size of the overlapping area determines the final mesh size. The operator can adjust it to the required specifications by observing the overlap of the mesh. In river management, the mesh size can be adjusted according to the changes in water flow during flood season and non-flood season. In highway slope protection, a small mesh size is used in the early stage of construction to prevent soil loss. The mesh size is increased after vegetation growth to reserve growth space. In emergency flood control scenarios, the mesh size can be quickly adjusted on-site to adapt to different particle sizes of filling stones and improve the efficiency of emergency rescue.

[0014] 2. This utility model achieves a tight fit between the wear-resistant ceramic coating and the gabion sub-mesh. The wear-resistant ceramic coating is made of alumina ceramic material and is attached to the surface of the gabion body and gabion sub-mesh through a thermal spraying process. Its hardness can reach HRA85 or higher, which can improve the wear resistance of the wire by 3 times, effectively resist the impact and wear of sand and gravel particles in high-speed water flow, and reduce fatigue damage to the gabion body and gabion sub-mesh.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The embodiments of this utility model will be described below based on its overall structure.

[0022] Please see Figure 1-4A gabion mesh with adjustable mesh size includes a gabion body 1. First connecting strips 2 are welded to both sides of the gabion body 1. The gabion body 1 and the first connecting strips 2 are arranged parallel to each other, and the first connecting strips 2 are symmetrically arranged about the central axis of the gabion body 1. An adjusting rod 3 is installed on the inner wall of the first connecting strip 2, and the first connecting strip 2 and the adjusting rod 3 are movably connected. The inner wall of the first connecting strip 2 has a slotted design. A second connecting strip 4 is fixedly connected to one end of the adjusting rod 3, and the adjusting rod 3 and the second connecting strip 4 are threaded together. The inner wall of the second connecting strip 4 is threaded. Locking blocks 5 are welded to the outer wall of the second connecting strip 4. Block 5 engages with the first connecting strip 2, and the blocks 5 are evenly spaced on the inner wall of the first connecting strip 2. The gabion mesh body 1 is made of woven alloy steel wire, with pre-reserved welding areas at its edges to fit the first connecting strip 2, ensuring connection strength. Both the first connecting strip 2 and the second connecting strip 4 are made of flat steel, with galvanized surfaces to enhance corrosion resistance. They are welded to the wire edges of the gabion mesh body 1 using carbon dioxide gas shielded welding. The second connecting strip 4 is connected to the gabion sub-mesh 6 using the same welding process. The adjusting rod 3 is made of threaded steel, with precision external threads machined on its surface, and engages with the first connecting strip 2. The end of the adjustable rod 3 is precisely fitted with the pre-set internal threaded hole at the end of the second connecting rod 4, forming a stable threaded connection. The two are linked through thread engagement. The gabion sub-mesh 6 is made of the same material and has the same initial mesh size as the gabion body 1. It is set parallel to one side of the gabion body 1, and its edge is fixed to the second connecting rod 4 by welding, forming a main and sub-mesh structure corresponding to the gabion body 1. In the initial state, the mesh size of the gabion sub-mesh 6 is completely aligned with the mesh size of the gabion body 1. At this time, the overall mesh size maintains the initial specification, ensuring the basic protection function. During adjustment, the operator can directly use a lever. Rotating the adjusting rod 3 by hand will convert the rotational motion into the linear motion of the second connecting bar 4. The mesh of the gabion sub-mesh 6 and the mesh of the gabion main body 1 will gradually change from complete alignment to partial overlap. The size of the overlapping area determines the final mesh size. Operators can adjust it to the required size by observing the overlap of the mesh. In river management, the mesh size can be adjusted according to the changes in water flow during flood season and non-flood season. In highway slope protection, small mesh sizes are used in the early stage of construction to prevent soil loss. Later, after vegetation grows, the mesh size is increased to reserve growth space. In emergency flood control scenarios, the mesh size can be quickly adjusted on-site to adapt to different particle sizes of filling stones, thereby improving the efficiency of emergency rescue.

[0023] Please see Figure 1-4A gabion mesh with adjustable mesh size is provided. The outer wall of the second connecting strip 4 is welded with a gabion sub-mesh 6. The outer wall of the gabion sub-mesh 6 is coated with a wear-resistant ceramic coating 7. The outer wall of the gabion sub-mesh 6 is tightly bonded to the inner wall of the wear-resistant ceramic coating 7, and the outer diameter of the gabion sub-mesh 6 is smaller than the inner diameter of the wear-resistant ceramic coating 7. By setting the gabion sub-mesh 6, the wear-resistant ceramic coating 7 is tightly bonded. The wear-resistant ceramic coating 7 is made of alumina ceramic material and is attached to the surface of the gabion mesh body 1 and the gabion sub-mesh 6 through a thermal spraying process. Its hardness can reach HRA85 or higher, which can improve the wear resistance of the mesh wire by 3 times, effectively resist the impact and wear of sand and gravel particles in high-speed water flow, and reduce fatigue damage to the gabion mesh body 1 and the gabion sub-mesh 6.

[0024] Working principle: In use, take out the device and place it in the designated position. Apply a wear-resistant ceramic coating 7 to the outer wall of the gabion mesh body 1 and gabion sub-mesh 6 using a thermal spraying process. Weld the gabion mesh body 1 to the first connecting strip 2 and then weld the second connecting strip 4 to the gabion sub-mesh 6. According to the usage requirements, rotate the first connecting strip 2 to the adjusting rod 3 and adjust the adjusting rod 3 to the second connecting strip 4 to the designated position using a threaded adjustment. Finally, misalign the gabion mesh body 1 and gabion sub-mesh 6 and adjust the mesh aperture to the designated size. This completes the use of the device.
