Description
Technical field
The utility model relates to earth working material field, a kind of shock-resistant anti-tear and possess the earth working material of anti-filter function specifically.
Background technology
The dykes and dams such as sea wall, shore protection class hydraulic structure generally uses heteromorphic block, block stone, mould-bag concrete etc. as the surface layer safeguard structure of water conservancy project dykes and dams class building, the feature of such mask is that water resistant stream and wave force are good, but that the deficiency existed is investment is large, construction is complicated and not easy-clear, if for the safeguard structure of dykes and dams class temporary structure, cost is too high and long in time limit.
Summary of the invention
The utility model, for overcoming the deficiencies in the prior art, designs a kind of less expensive, is easy to remove, do not affect later stage basement process, have the earth working material of shock-resistant and anti-tear effect simultaneously.
For achieving the above object, design a kind of shock-resistant anti-tear and possess the earth working material of anti-filter function, comprise geogrids layer, machine-woven fabric layer, nonwoven layer, is characterized in that: described machine-woven fabric layer is provided with nonwoven layer, and described nonwoven layer is provided with geogrids layer, described geogrids layer is selected spinnability filament fiber to make and is adopted through compiling oriented structure, and the crosspoint between the warp yarn of geogrids layer and weft yams is wrapped with fiber filament.
The specification of described machine-woven fabric layer is 150 ~ 1200g/ ㎡, and the specification of described nonwoven layer is 100 ~ 500g/ ㎡, and the specification of described geogrids layer is 150 ~ 800g/ ㎡.
By acupuncture composite joint between described machine-woven fabric layer and nonwoven layer, described geogrids layer is connected by hot fusion with between nonwoven layer.
Bending through the mutual nothing of weft yams of described geogrids layer.
The utility model compared with the existing technology, structure is simple, easy construction, be sewn into filling bag back-up sand material with this new geomaterial to fill dykes and dams and can realize dykes and dams and fill and synchronously carry out with dykes and dams construction of prevention work, be easy to remove, facilitate after provisional dam construction with adjoin being connected and later stage basement process of engineering; Fill dykes and dams for filling bag sand loading and synchronously can possess certain dykes and dams safeguard function, when water wave power is little without the need to other masks of row increase protection again, reduce investment outlay; Not easily produce electrostatic after friction, fire resistance is good, and anti-corrosion capability is strong, anti-aging; Soft, can not workman be scratched in construction, and there is easy curling bundling, easily cut out the advantage with light specific gravity, thus be convenient to transport, carry and construct; All there is stronger supporting capacity in direction in length and breadth.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model geo-grid.
See Fig. 1 ~ Fig. 2, wherein, 1 is geogrids layer, and 2 is nonwoven layer, and 3 is machine-woven fabric layer, and 4 is polyester dacron fibers, and 5 is fiber filaments.
Detailed description of the invention
With reference to the accompanying drawings the utility model is described further below.
As shown in Fig. 1 ~ Fig. 2, described machine-woven fabric layer 3 is provided with nonwoven layer 2, described nonwoven layer 2 is provided with geogrids layer 1, described geogrids layer 1 is selected spinnability filament fiber 4 to make and is adopted through compiling oriented structure, and the crosspoint between the warp yarn of geogrids layer 1 and weft yams is wrapped with fiber filament 5.
The specification of described machine-woven fabric layer 3 is 150 ~ 1200g/ ㎡, and the specification of described nonwoven layer 2 is 100 ~ 500g/ ㎡, and the specification of described geogrids layer 1 is 150 ~ 800g/ ㎡.
By acupuncture composite joint between described machine-woven fabric layer 3 and nonwoven layer 2, described geogrids layer 1 is connected by hot fusion with between nonwoven layer 2.
Bending through the mutual nothing of weft yams of described geogrids layer 1.
When the utility model uses, for different service conditions, the method that geogrids layer 1 and nonwoven layer 2 are merged by heat can be connected, the method that cold glue also can be used to bond connects two-layer.The mode merged by heat is connected two-layerly can improve composite effect, make cloth body globality better, intensity is higher; And connected by the mode that cold glue bonds and two-layer there is less investment, easy to process, the feature of not shrinking, not changing cloth body primary characteristic.
The polyester dacron filament fiber making geogrids layer can be replaced by the one in the composite filament of high density polyethylene (HDPE) filament fiber or chinlon 6 filament fiber or chinlon 66 filament fiber or above-mentioned filament fiber.
Wherein geogrids layer adopts infusion process dipping process, impregnation colloid is the one of polypropylene ester class or polyvinyl chloride or poly-Class C or pitch, simultaneously machine-woven fabric layer, nonwoven layer, geo-grid rubber shoe latex layer all add anti-ultraviolet aging material, and anti-ultraviolet aging material adopts a kind of or multiclass compound of inorganic carbon black or histamine class or triazines.
Embodiment one:
Use the woven fabric of 230 g/ ㎡ as bottom, the non-woven fabrics of 150 g/ ㎡ is as intermediate layer, the geo-grid of 150 g/ ㎡ is as top layer, wherein geo-grid is made up of polyester dacron filament fiber, and geo-grid adopts PVC material as the infusion process dipping process of impregnation colloid, adds the mixture of carbon black, triaizine compounds and histamine compound as anti-ultraviolet aging material in machine-woven fabric layer, nonwoven layer, geo-grid rubber shoe latex layer simultaneously.
Wherein adopt the method for attachment of acupuncture compound between machine-woven fabric layer and nonwoven layer, and the method for attachment that nonwoven layer and geogrids layer adopt heat to merge.
