Description

Technical Field

[0001] This utility model relates to a novel debris flow protection net, belonging to the field of protection net technology. Background Technology

[0002] Debris flows are a common and sudden geological disaster characterized by strong impact and wide destructive range. Therefore, debris flow protection nets are often set up in river valleys and valleys in areas prone to debris flows to reduce their harmfulness.

[0003] However, existing debris flow protection nets, mainly composed of wire mesh, still have significant shortcomings in practical applications: their lateral load-bearing capacity is weak, and most are only fixed at both ends with simple fasteners, lacking an effective lateral wire rope-coordinated load-bearing structure. When encountering a large-scale debris flow impact, the wire mesh is prone to deformation or even tearing due to excessive local stress. On the other hand, the load-bearing and stress-reducing design of the protection net is inadequate. It does not have components such as load-bearing buckles at key locations to disperse the instantaneous impact force, nor does it have a stress-reducing structure that can effectively buffer the impact force. The existence of these problems results in the limited load-bearing capacity of existing wire mesh protection nets. Utility Model Content

[0004] The purpose of this invention is to provide a new type of debris flow protection net to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A novel debris flow protection net includes a wire mesh and anchor bolts at both ends of the wire mesh; it is fixed to the riverbank slope by the anchor bolts; stress relief buckles are installed at both ends of the wire mesh, extending downwards from the upper side to the lower side; several transverse wire ropes are installed on the surface of the wire mesh, and protective steel is fixedly installed on the surface of the transverse wire ropes; several support columns are installed in the middle of the wire mesh; the support columns are fixed in the foundation below, and the support columns are reinforced with inclined steel wire ropes; the transverse wire ropes are fixedly connected to the support columns.

[0006] A further improvement to the technical solution of this utility model is that two support columns are set in the middle of the wire mesh.

[0007] A further improvement to the technical solution of this utility model is that the unloading buckle consists of several interlocking metal rings, and the metal ring corresponding to the transverse wire rope is fitted with the transverse wire rope.

[0008] A further improvement to the technical solution of this utility model is that 2-4 sets of unloading buckles are set at each end of the transverse steel wire rope.

[0009] A further improvement to the technical solution of this utility model is that the inclined steel wire rope is equipped with several stress-reducing rings.

[0010] A further improvement to the technical solution of this utility model is as follows: transverse steel wire ropes at the same position are grouped together; each group of transverse steel wire ropes contains 2-4 steel wire ropes; and a stress-reducing ring is set on the transverse steel wire ropes of the same group.

[0011] A further improvement to the technical solution of this utility model is as follows: Due to the adoption of the above technical solution, the technical effects achieved by this utility model are as follows: The debris flow protection net of this utility model uses steel wire mesh as the main body and is equipped with multiple sets of transverse steel wire ropes. By setting stress relief buckles at both ends of the steel wire mesh, setting support columns in the middle of the steel wire mesh, setting inclined steel wire ropes for the support columns, and setting stress reduction rings on the steel wire ropes, the above-mentioned structure improves the load-bearing capacity of the protection net and achieves a better protection effect against debris flows.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0015] This utility model is a new type of debris flow protection net, which is used to install in river channels, valleys and other locations where debris flows may occur, so as to protect against debris flows and reduce or mitigate them.

[0016] like Figure 1 , Figure 2As shown, the debris flow protection net mainly consists of a wire mesh 8 and anchor bolts 1 installed at both ends of the wire mesh 8. The wire mesh 8 is the main body of the protection net and is fixed in place by the anchor bolts connected at both ends. During installation, the anchor bolts 1 are fixed to the slopes of the river channel, valley, or mountain valley, and the wire mesh 8 is initially fixed to the slope.

[0017] To improve the stability of the wire mesh 8, several transverse wire ropes 3 are installed on the surface of the wire mesh 8. Multiple transverse wire ropes 3 are installed along the surface of the wire mesh 8 from top to bottom. Furthermore, protective steel is fixedly installed on the surface of the transverse wire ropes 3, improving their strength. In specific implementations, transverse wire ropes at the same height are preferably grouped together; each group of transverse wire ropes contains 2-4 wire ropes, and generally 3 wire ropes are used as a group of transverse wire ropes.

[0018] As shown in Figure 1, stress relief clips 2 are typically installed at both ends of the wire mesh 8 to reduce the stress during debris flows. The stress relief clips 2 are formed by sequentially nesting multiple metal rings, similar to a circular metal chain. The stress relief clips 2 are located at both ends of the wire mesh 8, extending downwards from the upper side to the lower side. The stress relief clips 2 have a certain length, and the metal rings of the stress relief clips 2, corresponding to the positions of the transverse wire ropes 3, are fitted together with the transverse wire ropes 3.

[0019] like Figure 1 , Figure 2 As shown, furthermore, several support columns 4 are set in the middle of the horizontal direction of the wire mesh 8, and the support columns 4 are set vertically. The wire mesh 8 and the horizontal wire ropes 3 are fixedly connected to the support columns 4. A concrete foundation 5 is set below the support columns 4 to fix the support columns 4 in the foundation 5. The support columns 4 are reinforced with diagonal wire ropes 6. A set of diagonal wire ropes 6 is used to mechanically reinforce the support columns 4 at both the front and back. The diagonal wire ropes 6 on both sides of the support columns 4 are symmetrically arranged to diagonally reinforce the support columns 4.

[0020] In practice, two support columns 4 are usually set in the middle of the wire mesh 8, or three or four support columns 4 can be set according to the transverse length of the wire mesh 8.

[0021] In practice, 2-4 sets of unloading buckles 2 are usually installed at both ends of the transverse steel wire rope 3 or at both ends of the steel wire mesh 8.

[0022] Several stress-reducing rings 7 are installed on the inclined steel wire rope 6. Stress-reducing rings 7 are also typically installed on the transverse steel wire ropes in the same group. The stress-reducing ring 7 is a commonly used stress-relieving structure in this technical field. Its general structure involves bending a metal tube into a ring shape, inserting the steel wire rope through one inlet of the metal tube, and then exiting through the other end of the metal tube. Stress-reducing rings are as follows... Figure 3As shown. The stress-reducing ring is a commonly used structure, and a brief illustration is provided here.

[0023] This utility model is a novel debris flow protection net. By setting stress relief buckles at both ends of the wire mesh and stress-reducing rings on the wire rope, the load-bearing capacity of the protection net is improved, thus achieving a good protective effect against debris flows.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
