Description

Technical Field

[0001] The invention belongs to the technical field of slope hanging net spraying, and in particular relates to a net splicing method for slope hanging nets. Background Art

[0002] Slope netting refers to a protective mesh structure installed on highway slopes. Its purpose is to prevent slope collapse due to geological disasters or other causes, thereby ensuring safe passage on the highway. The netting is typically made of high-strength steel wire mesh or polyester fiber mesh, secured to the slope with rebar or other fixing materials. The netting also helps consolidate soil and retain water, contributing to ecological restoration and environmental protection.

[0003] CN201921964669.7 discloses a quick fixing device for slope hanging nets, wherein the slope hanging nets are composed of interwoven grid lines, and the quick fixing device includes an anchor rod, a ferrule, a locking nut, and a pressure rod. The rear end of the anchor rod is provided with a threaded section, and the front end is used to drive into the mountain slope. The ferrule is sleeved on the anchor rod and can slide along the anchor rod. The locking nut is screwed onto the threaded section of the anchor rod and is located on the rear side of the ferrule. One end of the pressure rod is fixed on the ferrule, and the pressure rod is used to press the grid lines against the mountain slope. The quick fixing device of the present invention has a simple structure, is flexible and convenient to operate, reduces the difficulty of on-site construction, can quickly fix the slope hanging net, and is stable and reliable for a long time, reduces the maintenance cost of greening projects, and has good practicality.

[0004] The above technical solution is to drive the front end of the anchor rod into the rock mass (or soil) of the mountain slope at the position where the slope hanging net needs to be fixed, fix the anchor rod, and expose the bolt section of the anchor rod outside the slope. Then, put the ring piece on the anchor rod and push it toward the slope, so that the pressure rod presses the grid line against the mountain slope. Then, screw the locking nut on the threaded section of the anchor rod and press it against the rear side of the ring piece. The ring piece and the pressure rod are quickly fixed together on the mountain slope through the locking nut, so that the pressure rod presses the grid line tightly against the mountain slope. However, the above technical solution can only be used for compression, and cannot be used for splicing the net. During the installation of the net, there is usually a risk of the net being damaged. If damage occurs, it is very wasteful to directly replace the net. Summary of the Invention

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0026] Example 1

[0027] refer to Figure 1-10 , a mesh splicing method for a slope hanging net, the method relates to a mesh splicing device for a slope hanging net, the mesh splicing device for a slope hanging net comprises a column 1, a screw 2, a limit block 3, and a clamp 4, the outer side surface of the column 1 is provided with a symmetrically arranged convex groove 11, the clamp 4 is hinged to one end of the column 1 and is located in the convex groove 11, the outer side surface of the clamp 4 is provided with an arc 41 that matches the circumference of the outer side surface of the column 1, the other end of the column 1 is a conical structure, the column 1 is provided with an internal thread 12, the screw 2 is provided with an external thread 21 that matches the internal thread 12, the limit block 3 is movably connected to the screw 2, and the limit block 3 abuts against the inner side surface of the clamp 4 under the drive of the screw 2, and the method is specifically as follows:

[0028] Fix the column 1 between the two hanging nets to be spliced, so that the two hanging nets to be spliced ​​are placed in the convex groove 11, use the clamping claw 4 to clamp the two hanging nets to be spliced, movably connect the limit block 3 to the screw rod 2, and insert the screw rod 2 into the column 1, so that the limit block 3 abuts against the inner side of the clamping claw 4, and then further penetrate the column 1 into the slope to complete the splicing.

[0029] It should be noted here that, for the sake of convenience, this embodiment uses net A and net B to represent the two nets that need to be spliced ​​together. The net splicing device of the slope net in this embodiment can be used to fix net A and net B separately, and can also be used to splice net A and net B.

[0030] Under this design, a person skilled in the art first drives one end of the conical structure of the column 1 into the slope between the nets A and B to be assembled, then manually separates the clamping jaws 4, places the outermost parts of the nets A and B into the convex grooves 11, and releases the clamping jaws 4. At this time, the clamping jaws 4 will contact the nets A and B respectively, but the nets are easy to fall off without external force. At this time, the limit block 3 needs to be installed on the screw rod 2, and the external thread 21 on the screw rod 2 cooperates with the internal thread 12 of the column 1. Screw the screw 2 into the column 1. When it is screwed in to a certain depth, the top of the screw 2 will push the limit block 3 to abut against the inner surface of the clamp 4. At this time, the clamp 4 cannot swing. Finally, through the design of matching the arc 41 of the outer surface of the clamp 4 with the circumference of the outer surface of the column 1, the column 1 can be easily driven into the slope. During the driving process, the hanging nets A and B are further tightened under the drive of the clamp 4. In addition, the conical structure design at the other end of the column 1 can make it easier for the column 1 to be fixed deeply into the slope.

[0031] During the process of fixing the column 1 on the slope, the fixing depth should be controlled at the bottom of the convex groove 11, so that the outermost parts of the hanging nets A and B can be placed in the convex groove 11. During the second deep fixing process, the design of matching the outer surface arc 41 of the clamping jaw 4 with the circumference of the outer surface of the column 1 can avoid the difficulty of further deep fixing due to the outer surface of the clamping jaw 4 being too large. The depth of the second deep fixing needs to ensure that a part of the clamping jaw 4 is located in the slope, and the best is that the column 1 is completely entered into the slope.

[0032] Preferably, the convex groove 11 includes a horizontal groove 111 and a vertical groove 112, the vertical groove 112 is connected to the top of the column 1, and connecting rods 13 passing through the vertical groove 112 are provided on both sides of the vertical groove 112, and the clamping jaw 4 is provided with a through hole 42 passing through both sides of the clamping jaw 4, and the clamping jaw 4 is hinged to the connecting rod 13 through the through hole 42.

[0033] In actual application, the horizontal groove 111 is used to place the hanging net, and the vertical groove 112 is used to place the clamping jaw 4. After being clamped by the clamping jaw 4, the hanging net will first move toward the clamping jaw 4 during the process of being driven into the slope until it is clamped by the clamping jaw 4. In the subsequent driving process, the hanging net A and the hanging net B are further tightened under the drive of the clamping jaw 4.

[0034] Preferably, the projection of the clamping jaw 4 on the vertical plane is a parallelogram, and the clamping jaw 4 is provided with an upper inclined surface and a lower inclined surface. An arc portion 43 is provided between the upper inclined surface and the inner side surface of the clamping jaw 4, and the lower inclined surface of the clamping jaw 4 is provided with a strip groove 44 extending vertically upward from the lower inclined surface to the top of the inner side surface.

[0035] Specifically, when hinged, the place where the jaws 4 are hinged is close to the arc portion 43, so after hinged, the upper inclined surface of the jaws 4 protrudes from the top of the column 1. When opening the jaws 4, technical personnel in this field only need to press the outer side surfaces of the jaws 4 on both sides toward the axial direction of the column 1 to open it. The design of the arc portion 43 can increase the swing stroke of the jaws 4. The design of the strip groove 44 is because the hanging net has horizontal lines and vertical lines. If the jaws 4 clamp the horizontal lines, then the vertical lines can be placed in the strip groove 44; if the jaws 4 clamp the vertical lines, then the horizontal lines can be placed in the strip groove 44. Through such a design, the jaws 4 are fixed at the intersection of the horizontal lines and the longitudinal lines, which is more stable. In addition, the device can also be used for the purpose of fixing and compacting a single fixed net, and there is no position restriction.

[0036] Preferably, the limit block 3 is a T-shaped structure, and the limit block 3 includes a horizontal part 31 and a vertical part 32. The horizontal part 31 and the vertical part 32 are integrally formed. The limit block 3 is provided with a connecting hole 33 that passes through the horizontal part 31 and the vertical part 32. The limit block 3 is movably connected to the screw 2 through the connecting hole 33. When driven by the screw 2, the horizontal part 31 of the limit block 3 abuts against the upper inclined surface of the clamp 4.

[0037] Preferably, the horizontal portion 31 and the vertical portion 32 are both cylindrical structures. The cylindrical structure is adopted here because it ensures that the limit block 3 can accurately limit the clamping jaw 4 every time it is driven by the screw 2.

[0038] We found that if a quadrilateral is used, the limit block 3 will be limited earlier because the hypotenuse of the quadrilateral will be longer. Therefore, the limit block 3 in this embodiment adopts a cylindrical structure.

[0039] In this embodiment, a screw cap 22 is provided on the top of the screw rod 2. The screw cap 22 can facilitate the screw rod 2 to be screwed into the column 1.

[0040] Furthermore, the screw cap 22 is cylindrical in structure, and the outer side surface of the screw cap 22 is provided with a plurality of V-shaped grooves 221 arranged along the circumference of the screw cap 22. Due to cost and processing difficulty considerations, the use of a cylindrical structure as the screw cap 22 facilitates the screwing of the screw 2, and the V-shaped grooves 221 increase friction, making the design of the cylindrical screw cap 22 easier to rotate the screw 2.
