Abstract
The present invention relates to a kind of composite anti-penetrating geotextiles, including two layers of geotextiles top layer and the impervious barrier that is located between geotextiles top layer；The geotextiles top layer is connected by magic tape with impervious barrier；The geotextiles top 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 top layer of the composite anti-penetrating geotextiles of the present invention and impervious barrier, and had concurrently spin cloth and the advantages of non-woven fabrics, it is durable.
Description
Technical field
The present invention relates 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 sheeting as antiseepage base material with the non-woven fabric compounded geotechnique formed
Ooze material, its dominant mechanism is to separate earth dam leak paths with the impermeability of plastic sheeting, 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 acupuncture or
Hot sticky shaping, there is higher tensile strength and extensibility, after it is combined with plastic sheeting, not only increase the anti-of plastic sheeting
Tensile strength and puncture resistant ability, and because nonwoven surface is coarse, increases the coefficient of friction of contact surface, be advantageous to composite earth
The stabilization of work film and protective layer.
But intensity and durability are poor compared with Woven geofabric, are easily split from right angle orientation for non-woven geotextile, because
This existing anti-seepage geotextile has much room for improvement in terms of durability, and if will have and spin table of the cloth directly as anti-seepage geotextile
Layer, then it can make it that the recoverability of whole antiseepage cloth is deteriorated and the general coefficient of friction for having spinning cloth surface is less than non-woven fabrics, therefore
It can also affect on the stability that geotextiles are combined with plastic sheeting.
The content of the invention
In order to solve the above-mentioned technical problem, there is provided the good composite anti-penetrating geotechnique of a kind of intensity height, good endurance, recoverability
Cloth, the present invention provide following technical scheme：
A kind of composite anti-penetrating geotextiles, including two layers of geotextiles top layer and the antiseepage that is located between geotextiles top layer
Layer；The geotextiles top layer is connected by magic tape with impervious barrier；The geotextiles top 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 top layer of anti-seepage geotextile by the present invention, have both remained nonwoven soil
The advantages of work cloth is easily repaired, elasticity is good, further through the setting of Woven geofabric the intensity increase on top layer, durability are improved,
And in order to avoid Woven geofabric and impervious barrier frictional force deficiency the problem of, thread gluing is used between Woven geofabric and impervious barrier
Band connection, reparation and the recycling in later stage are also helped while ensureing and being reliably connected, when composite anti-penetrating geotextiles part is damaged
Bad when, replacement cost can be reduced.
Further, the hook surface of the both sides of the impervious barrier and magic tape bonds.
Further, the both sides of the impervious barrier and the hook surface of magic tape are integrally formed, and can be saved debanding glue and be protected
Card impervious barrier is reliably connected with geotextiles top 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.
Being between the top layer of the composite anti-penetrating geotextiles of the present invention and impervious barrier can be with when removably connecting, being damaged
The advantages of locally replacing, and having had spinning cloth and non-woven fabrics concurrently, durable, recoverability is high.

In figure：11st, non-woven geotechnical cloth layer, 12, Woven geofabric layer, 2, impervious barrier, 31, hair side, 32, hook surface.
Embodiment
A kind of composite anti-penetrating geotextiles as shown in Figure 1, including two layers of geotextiles top layer and it is located in geotextiles top layer
Between impervious barrier；The geotextiles top layer is connected by magic tape with impervious barrier；The geotextiles top 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 top 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 top 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 top layer of anti-seepage geotextile by the present invention, have both remained nonwoven soil
The advantages of work cloth is easily repaired, elasticity is good, further through the setting of Woven geofabric the intensity increase on top layer, durability are improved,
And in order to avoid Woven geofabric and impervious barrier frictional force deficiency the problem of, thread gluing is used between Woven geofabric and impervious barrier
Band connection, reparation and the recycling in later stage are also helped while ensureing and being reliably connected, when composite anti-penetrating geotextiles part is damaged
Bad when, replacement cost can be reduced.
Using it is above-mentioned according to desirable embodiment of the present invention as enlightenment, it is complete by above-mentioned description, relevant staff
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention'.This invention it is technical
Scope is not limited to the content on specification, it is necessary to determines its technical scope according to right.
