Abstract
The utility model relates to a machine-weaving non-woven compound geomembrane for engineering use, comprising at least three layers; wherein, the top layer is non-woven fabric, the bottom layer is machine weaving fabric, and the middle layer is plastic film; the bottom layer and the middle layer are formed by the extrusion, fusion, pressing and gluing of polymers; the non-woven fabric is pinpricked or hotbonded polymer short fiber chemical material; the machine weaving fabric is chemical filament; the plastic film can be PVC, PE, HDPE, LDPE, EVE. The utility model has the advantages of small specific gravity, strong extension ability, strong corrosion resistance, high intensity and strong antifreezing performance; therefore, the utility model can be widely used in the construction of dams of rivers, lakes, reservoir, as well as waste disposal factories, tunnels, slope protection projects and various structures for guarding against water, seepage and pollution.
Description
Technical field
The utility model relates to the geomembrane that a kind of engineering is used, particularly a kind of composite geo-membrane that woven fabric, adhesive-bonded fabric and plastic film effectively is combined in one.
Background technology
At present in the construction of river dyke, speedway, refuse landfill, railway tunnel, slope protection works and all kinds of buildings, the geomembrane kind of using as waterproof, antiseepage is a lot, as a cloth one film geomembrane and the intermediate layer plastic sheeting that is composited with layer of plastic film and layer of non-woven fabric, two-layer up and down respectively with non-woven fabric compounded two cloth, one film geomembrane that forms etc., facts have proved that the brute force of above geomembrane and stretching resistance all can not engineering demands.For satisfying engineering to powerful and stretching resistance requirement, have to the plastic sheeting thickening, but, rigidity thick because of diaphragm by force, composite geo-membrane is subjected to certain restriction in the application of earthwork engineering.
The utility model content
The purpose of this utility model provides a kind of powerful height, friction factor is big, stretching resistance is strong, the machine-weaving non-waving composite geomembrane of good penetrability.
The purpose of this utility model is achieved in that a kind of machine-weaving non-waving composite geomembrane, it is characterized in that composite geo-membrane has three layers at least, and the upper strata is an adhesive-bonded fabric, and bottom is a woven fabric, and the intermediate layer is a plastic film.
Described upper strata adhesive-bonded fabric is composited by extruded polymer fusion, crimping bonding between bottom woven fabric and the intermediate layer plastic film.
Described adhesive-bonded fabric is acupuncture or hot sticky polymeric staple fiber dimension chemical material.
Described woven fabric is the chemical-fibres filaments woven fabric.
Described plastic film is diaphragms such as PVC, PE, HDPE, LDPE, EVA.
Adhesive-bonded fabric is adopted on the utility model machine-weaving non-waving composite geomembrane upper strata, and nonwoven surface is coarse, has increased the friction factor of contact surface, helps the stable of composite geo-membrane and topping; And lower floor adopts the chemical-fibres filaments woven fabric, the intermediate layer plastic film, because plastic film is to be formed by high-temperature fusion extruding crimping by a kind of polymer chemistry flexible material, it is little to have proportion, extensibility is stronger, corrosion-resistant, good frost resistance, and the chemical-fibres filaments woven fabric is powerful high, tensile property is good, with adhesive-bonded fabric, woven fabric, the composite earthwork diaphragm that plastic film effectively combines has higher intensity and more performance, can be widely used in various rivers, the river, the lake, reservoir dam, refuse landfill, railway tunnel, in the construction of slope protection works and all kinds of buildings, as waterproof, antiseepage, anti-pollution usefulness.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1 adhesive-bonded fabric, 2 plastic films, 3 woven fabrics.
The specific embodiment:
Embodiment 1
Fig. 1 has provided the utility model structural representation.The upper strata is a terylene short fiber needle-punched non-woven fabric 1, and lower floor is a polypropylene filament yarn woven fabric 3, with the intermediate layer be EVA plastic film 2 by fusion, crimping is bonding is composited.This composite membrane has flexible good, characteristics such as obdurability is high, adaptive temperature wide ranges, is applicable to the underground construction of complex-terrains such as subway, tunnel.
The upper strata is a terylene short fiber hot melt adhesive-bonded fabric 1, and lower floor is a polyester filament woven fabric 3, with the intermediate layer be HDPE plastic film 2 by fusion, crimping is bonding is composited.Characteristics such as this composite membrane adopts the manufacturing of high density polyethylene (HDPE) raw material, has environmental stress cracking resistance, and chemical resistance is good, and impervious ability is strong, and thermal deformation is little are applicable to that refuse landfill, sewage dirt are handled the field, mine tailing stores engineerings such as field, body tunnel, hole.
