Embodiment 1

[0014] Embodiment 1: as attached figure 1 , figure 2 As shown, an asphalt composite coating anti-cracking cloth includes a non-woven fabric layer 4 and a bar layer, and the bar layer is formed by interlacing horizontal bar 1 and longitudinal bar 2, and The surface is provided with a grid-like reinforcement layer, and the grid-like reinforcement layer adopts two comb bars, wherein the organizational structure of L1 is 1-0 / 1-2 / / full wear, and the yarn feeding amount is 7000mm / R, The organizational structure of L2 is 1-2 / 1-0 / / full wear, and the yarn feeding amount is 7000mm / R. The back side of the non-woven fabric layer 4 is provided with a strip-shaped reinforced layer, which is followed by a grid-shaped reinforced layer, a grid layer, a non-woven fabric layer and a strip-shaped reinforced layer from top to bottom. After the four layers are combined, the The upper and lower surfaces are coated with slurry layers respectively. Both the grid-shaped reinforcing layer and the st...

Embodiment 2

[0015] Embodiment 2: another asphalt composite coating anti-cracking cloth, the specification of the binding yarn is 111dtex. The horizontal grid bar and the vertical grid bar respectively include 1 strand, and its specification is 44444dtex. The non-woven fabric layer is a polypropylene spunbonded non-woven fabric layer. In fact, it is the same as Embodiment 1.

Embodiment 3

[0016] Embodiment 3: Another asphalt composite coating anti-cracking cloth, the specification of the binding yarn is 333dtex. The horizontal grid bar and the vertical grid bar respectively include 3 strands, and their specifications are 11111dtex. The non-woven fabric layer is a polyester spunbonded non-woven fabric layer. In fact, it is the same as Embodiment 1.

Abstract

The invention discloses asphalt composite coating layer anti-cracking cloth. The asphalt composite coating layer anti-cracking cloth comprises a non-woven cloth layer and a grid layer; the grid layer is formed by arranging transverse grids and longitudinal grids in a staggered manner; a latticed reinforcing layer is arranged on the surface of the grid layer; a strip reinforcing layer is arranged on the back surface of the non-woven cloth layer; the latticed reinforcing layer and the strip reinforcing layer are both formed by interweaving binding yarns; the latticed reinforcing layer, the grid layer, the non-woven cloth layer and the strip reinforcing layer are arranged in sequence from top to bottom; and pulp layers are respectively coated on the upper and lower surfaces of the four layers after combination. The bursting strength of knots and grids and the peeling strength of the knots are improved; and the grids are effectively prevented from displacing.

Description

technical field [0001] The invention relates to a geotechnical reinforcing material, in particular to an asphalt composite coating anti-cracking cloth. Background technique [0002] At present, geotechnical reinforcement materials generally include plastic grids and glass fiber grids. Plastic grids have the characteristics of small creep, corrosion resistance, anti-aging, large friction coefficient, convenient construction, and long service life. They can adapt to various environmental soils and can Effectively improve the interlocking and occlusion of the reinforced bearing surface, greatly enhance the bearing capacity of the foundation, effectively restrain the lateral displacement of the soil, and enhance the stability of the foundation, which can fully meet the tall retaining walls in high-grade highways use. However, the existing market plastic grating is made of high molecular polymer through extrusion, plate forming, punching process and then stretched longitudinally...
