Description

Technical Field

[0001] The utility model relates to the technical field related to road construction, in particular to a road reinforcement mesh structure. Background Art

[0002] Pavement reinforcement mesh is a new type of pavement reinforcement technology. It is a three-dimensional structure laid in the pavement structure layer. It makes the pavement as a whole through a continuous mesh structure, which can greatly improve the bearing capacity of the pavement structure. With the increase of traffic load and the extension of road service life, the application of pavement reinforcement mesh technology in actual engineering is becoming more and more extensive.

[0003] The current pavement reinforcement mesh is achieved by adding reinforcing ribs to the double-twisted steel wire mesh surface. However, since the transverse reinforcing ribs of this structure are in the form of straight wires, they are prone to wire slippage under long-term loads. This, together with the attenuation of the asphalt anchoring performance, will lead to a reduction in the service life of the road. Utility Model Content

[0006] Furthermore, the double-twisted steel wire mesh surface is formed by twisting two adjacent metal wires arranged in the same direction to form an orderly mesh surface.

[0008] Furthermore, both ends of the reinforcing rod are sleeved with metal washers, and the metal washers are located between the fastening nuts and the side edges of the double-twisted steel wire mesh.

[0009] Furthermore, the bending portion is curled on the reinforcing rod, and the limiting steel wire connects the two reinforcing rods through the bending portion.

[0010] Furthermore, the limiting steel wires are equidistantly distributed on the double-twisted steel wire mesh surface, and the bent portions at both ends of the limiting steel wires are arranged on both sides of the twisted portion of the double-twisted steel wire mesh surface.

[0011] Compared with the existing technology, the present invention provides a pavement reinforcement mesh structure with the following beneficial effects:

[0012] The pavement reinforcement mesh structure has fastening nuts and limit nuts threadedly installed at both ends of the reinforcement rods, which can fix the position of the reinforcement rods. At the same time, the limit steel wires set can also strengthen the limitation of the reinforcement rods.
