Abstract
The utility model is related to a kind of composite anti-penetrating geotextiles, including two layers of geotextiles surface layer and the impervious barrier being located between geotextiles surface layer；The geotextiles surface layer is connect by magic tape with impervious barrier；The geotextiles surface layer includes non-woven geotechnical cloth layer and Woven geofabric layer, and the Woven geofabric layer is fixed by the hair side of needle point method and magic tape, and the both sides of the impervious barrier and the hook surface of magic tape are pasted.Be that can locally be replaced when removably connecting, being damaged between the surface layer of the composite anti-penetrating geotextiles of the utility model and impervious barrier, and the advantages of had both woven fabric and non-woven fabrics, it is durable.
Description
Technical field
The utility model is related to garbage loading embeading impervious material technology more particularly to a kind of composite anti-penetrating geotextiles.
Background technology
Existing anti-seepage geotextile is prevented generally using plastic film as antiseepage base material with the non-woven fabric compounded geotechnique formed
Ooze material, dominant mechanism is to separate earth dam leak paths with the impermeability of plastic film, with its larger tensile strength and
Elongation percentage bears hydraulic pressure and adapts to dam deformation；And non-woven fabrics is also a kind of polymeric staple fiber dimension chemical material, by needle thorn or
Hot sticky forming has higher tensile strength and extensibility, after it is combined with plastic film, not only increases the anti-of plastic film
Tensile strength and puncture resistant ability, and since nonwoven surface is coarse, increases the friction coefficient of contact surface, be conducive to composite earth
The stabilization of work film and protective layer.
But intensity and durability are poor compared with Woven geofabric, easily split from right angle orientation for non-woven geotextile, because
This existing anti-seepage geotextile is to be improved in terms of durability, and if will have table of the woven fabric directly as anti-seepage geotextile
Layer can then so that the recoverability of entire antiseepage cloth is deteriorated and the general friction coefficient for having woven fabric surface is less than non-woven fabrics, therefore
It can also affect on the stability that geotextiles are combined with plastic film.
Utility model content
In order to solve the above-mentioned technical problem, the composite anti-penetrating geotechnique that a kind of intensity is high, durability is good, recoverability is good is provided
Cloth, the utility model provide following technical scheme：
A kind of composite anti-penetrating geotextiles, including two layers of geotextiles surface layer and the antiseepage being located between geotextiles surface layer
Layer；The geotextiles surface layer is connect by magic tape with impervious barrier；The geotextiles surface layer includes non-woven geotechnical cloth layer and has spinning
Geotextile layer, the Woven geofabric layer are fixed by the hair side of needle point method and magic tape, the both sides of the impervious barrier and thread gluing
The hook surface connection of band.
Non-woven geotextile and Woven geofabric are combined as the surface layer of anti-seepage geotextile by the utility model, both remain nothing
The advantages of geotextiles are easily repaired, elasticity is good is spun, further through the setting of Woven geofabric so that the intensity on surface layer increases, durability carries
Height, and used in order to avoid Woven geofabric and the hypodynamic problem of impervious barrier friction, between Woven geofabric and impervious barrier
Thread gluing band connection also helps reparation and the recycling in later stage, when composite anti-penetrating geotextiles portion while ensureing and being reliably connected
Divide during damage, replacement cost can be reduced.
Further, the hook surface of the both sides of the impervious barrier and magic tape bonds.
Further, the hook surface of the both sides of the impervious barrier and magic tape is integrally formed, and can be saved debanding glue and be protected
Card impervious barrier is reliably connected with geotextiles surface layer.
Further, the impervious barrier is HDPE plastic layer.
Further, the non-woven geotechnical cloth layer and the thickness ratio of Woven geofabric layer are 2-3：1.
It is when removably connecting, being damaged between the surface layer of the composite anti-penetrating geotextiles of the utility model and impervious barrier
The advantages of can locally replacing, and having had both woven fabric and non-woven fabrics, durable, recoverability is high.
Description of the drawings
The primary structure schematic diagram of Fig. 1, the utility model.
In figure：11st, non-woven geotechnical cloth layer, 12, Woven geofabric layer, 2, impervious barrier, 31, hair side, 32, hook surface.
Specific embodiment
A kind of composite anti-penetrating geotextiles as shown in Figure 1, including two layers of geotextiles surface layer and are located in geotextiles surface layer
Between impervious barrier；The geotextiles surface layer is connect by magic tape with impervious barrier；The geotextiles surface layer includes nonwoven geotechnique
Layer of cloth and Woven geofabric layer, the Woven geofabric layer are fixed by the hair side of needle point method and magic tape, the impervious barrier
The hook surface of both sides and magic tape connects.The both sides of the impervious barrier and the hook surface of magic tape are integrally formed, and can save debanding use
Glue simultaneously ensures being reliably connected for impervious barrier and geotextiles surface layer.The impervious barrier is HDPE plastic layer.Described in the present embodiment
The thickness of impervious barrier is 1.5mm, the thickness on geotextiles surface layer is 2-3mm, wherein non-woven geotechnical cloth layer and Woven geofabric layer
Thickness ratio is 2-3：1.
Non-woven geotextile and Woven geofabric are combined as the surface layer of anti-seepage geotextile by the utility model, both remain nothing
The advantages of geotextiles are easily repaired, elasticity is good is spun, further through the setting of Woven geofabric so that the intensity on surface layer increases, durability carries
Height, and used in order to avoid Woven geofabric and the hypodynamic problem of impervious barrier friction, between Woven geofabric and impervious barrier
Thread gluing band connection also helps reparation and the recycling in later stage, when composite anti-penetrating geotextiles portion while ensureing and being reliably connected
Divide during damage, replacement cost can be reduced.
Using above-mentioned foundation the utility model desirable embodiment as enlightenment, pass through above-mentioned description, relevant staff
Various changes and amendments can be carried out in the range of without departing from this item utility model technological thought completely.This item is practical
Novel technical scope is not limited to the content on specification, it is necessary to determine that its is technical according to right
Range.
