Description

Technical Field

[0001] The utility model relates to the field of composite geonet mats, in particular to a high-strength composite geonet mat. Background Art

[0002] Geonet is a common building material and is widely used in construction projects. However, the existing geonets are all mesh structures woven with polyethylene. This mesh structure has certain advantages in improving the stability of the roadbed. However, in some special construction environments, the geonet is often required to have not only good tensile properties, but also certain anti-seepage properties. This has gradually led to the emergence of a composite geonet structure with a geonet as the base and a geomembrane on top.

[0003] In the prior art, traditional geogrid products are made of tight three-dimensional polypropylene or polyethylene filaments as the skeleton, and are compounded with one or two layers of non-woven fabrics. As a result, when people use the geogrid, due to the low strength of the geogrid and the influence of factors such as the external environment, it is easy to be torn and damaged, thereby reducing the service life of the geogrid and affecting people's use.

[0011] Preferably, the flame-retardant breathable cotton is fixedly installed on the top surface of the glass fiber strips and the steel wire strips, and the non-woven fabric is fixedly installed on the top surface of the flame-retardant breathable cotton.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the utility model, the composite geogrid is formed by adding a reinforcement layer between the three-dimensional polypropylene wire skeleton layer and the non-woven fabric, and the anti-high temperature and low temperature resistance of the composite geogrid is improved by antifreeze breathable cotton and flame retardant breathable cotton, so as to avoid the problem of spontaneous combustion of the composite geogrid at high temperature and freezing and fracture at low temperature, so that the composite geogrid has weather resistance when used, and the structural strength of the three-dimensional polypropylene wire skeleton layer can be increased by the steel wire mesh, and the tensile, bending and shear strength of the composite geogrid when used can be further improved by the mesh structure woven by glass fiber strips and steel wire strips, so as to effectively enhance the use strength of the composite geogrid, and then ensure that the composite geogrid will not be broken or damaged when used, which not only improves the service life of the composite geogrid, but also makes it convenient for people to use.
