Problems solved by technology
[0002] At present, geotextiles are widely used in water conservancy, ports, waterways, railways, highways and other projects with small sediment diameter and high stress, used for reverse filtration, soft foundation treatment, bank protection and slope protection, etc., but the current geotextile structure is too simple. The strength is not high, because of its low tensile strength and high elongation, it cannot meet the requirements of geotechnical engineering

Embodiment Construction
[0009] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0010] Such as figure 1 A polyethylene geotextile compounded with micropinholes is shown, including woven geotextile layer 1, non-woven fabric layer 2 and polyethylene mesh 3, woven geotextile layer 1, non-woven fabric layer 2 and polyethylene mesh The net 3 is compounded into a whole base cloth by needle punching, the polyethylene net 3 is made of polyethylene monofilament, the diameter of the polyethylene monofilament is 0.6-0.63mm, the woven geotextile layer 1 and the non-woven fabric layer 2 and the polyethylene The density of the pinholes of the mesh 3 after compounding is 2.0 to 3.2 pins / mm 2 .
[0011] Inspired by the above-mentioned ideal embodiment a...

Abstract
The invention relates to polyethylene geotechnical cloth compounded with micro pinholes. The polyethylene geotechnical cloth comprises a woven geotechnical cloth layer, a non-woven fabric layer and a polyethylene net, wherein the woven geotechnical cloth layer, the non-woven fabric layer and the polyethylene net are compounded into whole base cloth through needling; the polyethylene net is made of polyethylene monofilaments; the diameter of the polyethylene monofilament is 0.6-0.63mm; the density of the compounded pinholes of the woven geotechnical cloth layer, the non-woven fabric layer and the polyethylene net is 2.0-3.2 needles per square millimeters. The polyethylene geotechnical cloth compounded with micro pinholes is simple in structure, light in weight, low in cost, high in strength and strong in permeability and peel strength.
Description
technical field [0001] The invention relates to the field of civil engineering, in particular to a polyethylene geotextile compounded with micro-pinholes. Background technique [0002] At present, geotextiles are widely used in water conservancy, ports, waterways, railways, highways and other projects with small sediment diameter and high stress, used for reverse filtration, soft foundation treatment, bank protection and slope protection, etc., but the current geotextile structure is too simple. The strength is not high, because of its low tensile strength and high elongation, it cannot meet the requirements of geotechnical engineering. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to overcome the above-mentioned problems, a polyethylene geotextile compounded with micro-pinholes is provided, which has a reasonable design structure and high tensile strength. [0004] The technical solution adopted by the present...
