Embodiment 1

[0016] Such as figure 1 Shown, a kind of reinforced three-dimensional geotechnical mat, comprises geogrid layer 2, non-woven fabric layer 3 and mesh layer 1, and described mesh layer 1 adopts plastic spraying machine to spray nylon polyamide or polypropylene on The coating layer formed on the outer surface of the geogrid layer 2, the mesh diameter in the mesh layer 1 is 0.1-2.0mm, the porosity is 95%, the thickness of the mesh layer 1 is 20mm, and the mesh layer 1 The lower surface of the melt-blown non-woven fabric layer 3, the three-dimensional geotextile mat in the present embodiment, laying on both sides of the road can play the role of preventing water and soil erosion, because the porosity of the mesh layer 1 is relatively large, in the mesh layer The soil filling in 1 is uniform, the effect of soil fixing is good, and the purpose of rapid drainage can be achieved when the rain washes away. The non-woven fabric layer 3 is made of a non-woven fabric compound machine and m...

Embodiment 2

[0019] Such as figure 2 As shown, a reinforced three-dimensional geotechnical mat, the outer surface of the geogrid layer 2 is sprayed with a mesh layer 1, and the upper and lower surfaces of the mesh layer 1 are provided with a non-woven layer 3, and the non-woven The cloth layer 3 has a good isolation effect and has the functions of filtering and anti-clogging. It can be applied to garbage filtration and sea surface degreasing. Solid or granular garbage is isolated on the upper surface of the non-woven fabric layer 3, and the liquid passes through the mesh layer 1 , The lower non-woven fabric layer is discharged, and at the same time, it can also prevent granular impurities and stones from clogging the mesh layer or splitting the mesh layer 1, which plays a certain protective role.

[0020] The reinforced three-dimensional geotechnical mat of the present invention tightly fixes the geogrid with reinforcing effect and the non-woven fabric with filtering and isolating effect ...

Abstract

The invention discloses a reinforced three-dimensional geotechnical pad. The reinforced three-dimensional geotechnical pad comprises a geogrid layer, a nonwoven cloth layer and a net wire layer, and is characterized in that the net wire layer is a coating layer formed by spraying nylon polyacyl or polypropylene wires on the outer surface of the geogrid layer by a plastic injecting machine; and the nonwoven cloth layer is sprayed on the upper surface and / or the lower surface of the net wire layer. The reinforced three-dimensional geotechnical pad tightly fixes geogrid with a reinforced effect and nonwoven cloth with a filter isolation effect, after hot melting, with the net wire layer, so that the tensile strength of a geonet pad is increased from conventional 10 KN / m to above 150 KN / m; and compared with a traditional geotechnical pad, the reinforced three-dimensional geotechnical pad improves the strength by multiple times, adds effects of soil reinforcement and scour prevention, effectively solves the defect of easy blockage of the traditional geotechnical pad in long-time rainwater and river water scouring or stressed state, and improves a river levee or road protecting effect.

Description

technical field [0001] The invention relates to a protective mesh pad, in particular to a reinforced three-dimensional geotechnical pad. Background technique [0002] At present, geonet mats are widely used in water conservancy slope protection, greening, anti-scouring, waterproof soil loss, reinforcement, anti-seepage, garbage treatment, sewage treatment and other fields. However, due to the network structure of the existing geotextile mat, it is easy to deform or even break under tension, and cannot play the role of reinforcement; under pressure, it will be silted up, and the anti-seepage filtering effect will be greatly reduced. Can not play the effect of preventing soil erosion simultaneously. Contents of the invention [0003] The purpose of the present invention is to provide a reinforced three-dimensional geotechnical mat, which solves the defects of low tensile strength, easy silting and poor filtering effect of existing geotechnical mats, and also has the functio...
