Description

Technical Field

[0001] The utility model belongs to the technical field of metal meshes, and particularly relates to a slope protection metal mesh. Background Art

[0002] In order to prevent landslides caused by debris flows, earthquakes and other reasons, slope protection metal meshes are covered on the mountainsides on both sides of railways, highways or other passages. The existing slope protection metal meshes include mesh sheets and mesh sheet fixing ropes. The mesh sheets are fixed on the mountainside through the mesh sheet fixing ropes. In order to improve the impact resistance of the mesh sheets, a plurality of anchor bolts are arranged on the mountainside to anchor the mesh sheets on the mountainside. The existing slope protection metal meshes have the following defects: First, due to factors such as the cost of the mesh sheets, the wire diameter of the metal wires of the mesh sheets is generally not large, so the overall impact resistance of the mesh sheets is poor. When larger stones fall off, the mesh sheets can be broken and fall from the mountainside, causing harm to vehicles or pedestrians on the highway or railway and the highway or railway, and need to be replaced again; the service life of the mesh sheets is short and the impact resistance is poor; Second, in order to increase the impact resistance of the mesh sheets, the number of anchor bolts per unit area is increased, which increases the construction difficulty and the construction cost. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a slope protection metal mesh with a long service life, strong impact resistance and convenient construction.

[0004] To solve the above problems, the technical solution adopted by the slope protection metal mesh of the utility model is as follows: It includes multiple sub-mesh sheets woven by wavy thin wires. Longitudinal reinforcing wires are arranged between adjacent sub-mesh sheets. The longitudinal reinforcing wires are woven together with the outermost wavy thin wires of the adjacent sub-mesh sheets. The longitudinal reinforcing wires connect multiple sub-mesh sheets into a whole mesh sheet. Frame wires are arranged on the two outermost sub-mesh sheets. The frame wires are woven together with the edges of the outermost sub-mesh sheets. Transverse reinforcing wires perpendicular to the frame wires are arranged at intervals on the whole mesh sheet between the frame wires. The weaving joints of the transverse reinforcing wires in the whole mesh sheet are woven together with the whole mesh sheet.

[0005] Its additional technical features are as follows:

[0006] The longitudinal reinforcing wires are wavy;

[0007] Both ends of the transverse reinforcing wires bypass the frame wires and are folded in half. Folding snap rings are arranged on the folded transverse reinforcing wires.

[0008] Compared with the prior art, the slope protection metal net provided by the utility model has the following advantages: First, since it includes multiple sub-net pieces woven by wavy fine wires, longitudinal strengthening wires are arranged between adjacent sub-net pieces. The longitudinal strengthening wires are woven together with the outermost wavy fine wires of the adjacent sub-net pieces. The longitudinal strengthening wires connect multiple sub-net pieces into a whole net piece. Frame wires are arranged on the two outermost sub-net pieces. The frame wires are woven together with the edges of the outermost sub-net pieces. Transverse strengthening wires perpendicular to the frame wires are arranged at intervals on the whole net piece between the frame wires. The transverse strengthening wires are woven together with the whole net piece at the weaving joints in the whole net piece. Compared with the net piece woven into large mesh holes, when small stones fall, the impact force is small, and the sub-net pieces woven by wavy fine wires can block them. When large stones fall, the large stones are caught by the adjacent longitudinal strengthening wires and transverse strengthening wires. Because the diameters of the longitudinal strengthening wires and transverse strengthening wires are relatively thick, the impact resistance is greatly enhanced, the net piece will not be broken, and the large stones will not fall, avoiding harm to pedestrians or vehicles on highways, railways, or roads or railways, extending the service life of the entire slope protection metal net, and being convenient for construction. It can effectively reduce the number of anchor rods, reducing the construction difficulty and construction cost. Second, the longitudinal strengthening wires are wavy, making the weaving more convenient and the mesh holes more uniform. When being impacted by stones, the longitudinal strengthening wires can elongate, improving the impact resistance of the net piece. Third, since both ends of the transverse strengthening wires bypass the frame wires and are folded in half, and folding clasps are arranged on the folded transverse strengthening wires, it is convenient for processing. Moreover, the effective utilization length of the transverse strengthening wires can also be extended when being impacted by stones, further improving the impact resistance of the entire net piece.

[0013] The following further elaborates in detail on the structure and usage principle of the slope protection metal net of the utility model in conjunction with the drawings and specific embodiments.

[0014] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, it is a schematic structural diagram of the slope protection metal net of the present utility model. The slope protection metal net of the present utility model includes multiple sub-net pieces 2 woven by wavy thin wires 1. Between adjacent sub-net pieces 2, longitudinal strengthening wires 3 are provided. The longitudinal strengthening wires 3 are woven together with the outermost wavy thin wires 1 of the adjacent sub-net pieces. The longitudinal strengthening wires 3 connect multiple sub-net pieces 2 into a whole net piece. On the outermost two sub-net pieces 2, border wires 4 are provided. The border wires 4 are woven together with the wavy thin wires 1 at the edges of the outermost sub-net pieces 2. On the whole net piece between the border wires 4, transverse strengthening wires 5 perpendicular to the border wires 4 are arranged at intervals. The weaving joints of the transverse strengthening wires 5 in the whole net piece are woven together with the whole net piece.

[0015] Compared with the net piece woven into large mesh holes, the transverse strengthening wires 3 and the transverse strengthening wires 5 have a small impact force when small stones fall, and the sub-net pieces 2 woven by the wavy thin wires 1 can block them. When large stones fall, the large stones are caught by the adjacent longitudinal strengthening wires 3 and transverse strengthening wires 5. Because the diameters of the longitudinal strengthening wires 3 and the transverse strengthening wires 5 are relatively thick, the impact resistance is greatly enhanced, the net piece will not be broken, and the large stones will not fall, avoiding damage to pedestrians or vehicles on highways, railways, or roads or railways, extending the service life of the entire slope protection metal net, and being convenient for construction. It can effectively reduce the number of anchor bolts, reducing the construction difficulty and construction cost.

[0016] The longitudinal strengthening wires 3 are wavy, which is more convenient for weaving, the mesh holes are more uniform, and when being impacted by stones, the longitudinal strengthening wires can elongate, improving the impact resistance of the net piece.

[0017] Both ends of the transverse strengthening wire 5 bypass the border wire 4 and are folded in half. On the folded transverse strengthening wire 5, a folded snap ring 6 is provided, which is convenient for processing. Moreover, the effective utilization length of the transverse strengthening wire can be extended when being impacted by stones, further improving the impact resistance of the whole net piece.

[0018] The protection scope of the present utility model is not limited to the above embodiments. As long as the structure is the same as or similar to the structure of the slope protection metal net of the present utility model, it falls within the protection scope of the present utility model.
