Description
Technical field
The utility model relates to a kind of earth working material, specifically a kind of single matt-surface composite geomembrane, belongs to geotechnique's material
Material field.
Background technology
Currently, during China's capital construction, substantial amounts of water proof anti-seepage engineering is related to, in order to solve the waterproof anti-of engineering
Ooze and use common geomembrane in a large number, but this single geomembrane is in engineering use, exposes environmental stress crack resistance
Difference, poor toughness, intensity is low, not weakness such as puncture-resistant, often leads to the decline of the impervious effect of engineering integral waterproofing.Entitled " one
The Chinese invention patent of kind of composite geo-membrane " Application No. " 201510792965.3 " discloses a kind of composite geo-membrane, from upper
Down including geogrids layer, impervious barrier and geomembrane body successively, geogrids layer is compounded in the upper table of described impervious barrier
Face, the lower surface of geomembrane body has crude face and pointed lug boss for increasing friction force, if pointed lug boss is
It dry, is evenly distributed on the lower surface of geomembrane body.But, this product structure splicing effect is poor, and after splicing, firmness is not
Enough, and tensile strength and non-deformability are weak, reduce product quality.
Utility model content
In order to solve the problems referred to above, the utility model devises a kind of single matt-surface composite geomembrane, and splicing effect is good, splicing
Firmly, good seepage-proof property, fracture strength is high, and tearing toughness is good, improves skid resistance, and product quality is high.
The technical solution of the utility model is:
Single matt-surface composite geomembrane, including high-density polyethylene geomembrane layer, described high-density polyethylene geomembrane layer
Upper surface is provided with projection, and the antiseepage film layer that surface is provided with projection can form stronger snap-in force with soil property, stops soil material
Glide, increasing friction force, strengthen waterproof, seepage control performance；The downside of described high-density polyethylene geomembrane layer is provided with acupuncture geotechnique
Cloth, described needle-punched geotextiles be polyvinyl resin bar by thermoplastic, mold or be bonded in described high-density polyethylene geomembrane layer
On, so that needle-punched geotextiles embeds geomembrane.
Further, the surface of described needle-punched geotextiles is also installed with two reinforcements, two described reinforcements
Respectively interlock be fixed on two diagonal of described needle-punched geotextiles, be prevented from needle-punched geotextiles center sink and
Cause needle-punched geotextiles deformation to depart from from geo membrane layers, improve the firmness of product.
Further, the end lower surface of described needle-punched geotextiles has multiple longitudinal water guide groove, described water guide groove
End is provided with the guide pillar that drips, and ponding is derived from water guide groove, finally drips from the guide pillar that drips, in time by needle-punched geotextiles and soil
Ponding between work film layer is discharged, in case needle-punched geotextiles departs from geo membrane layers, further increases the firmness of product.
Further, the both sides of described geo membrane layers and needle-punched geotextiles are separated, and form breach, thus can realize many
Block composite geo-membrane overlap joint coordinates, and overlap joint fitness is high, and easy construction and overall flexibility are good, and service life is long.
Further, described indentation, there is embedded with resin streak, and resin streak can increase in composite geo-membrane surrounding medium circle
Add the coefficient of friction between composite geo-membrane and surrounding medium interface, strengthen the friction between composite geo-membrane and surrounding medium
Power, form stronger snap-in force with surrounding medium, it is to avoid the phenomenon gliding occurs at side slope in engineering for the composite geo-membrane,
Improve the stability of all kinds of engineering.
The utility model has the advantage of: splicing effect is good, firmly, good seepage-proof property, fracture strength is high, tear-proof in splicing
Intensity is good, improves skid resistance, and product quality is high.
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Brief description
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Hereinafter preferred embodiment of the present utility model is illustrated, it will be appreciated that preferred embodiment described herein
It is merely to illustrate and explains the utility model, being not used to limit the utility model.
Embodiment 1
As it is shown in figure 1, a kind of single matt-surface composite geomembrane, including high-density polyethylene geomembrane layer 1, described high density is gathered
The upper surface of ethene geo membrane layers 1 is provided with protruding 2, and the antiseepage film layer that surface is provided with projection can form stronger being engaged with soil property
Power, stops soil material to glide, and increasing friction force strengthens waterproof, seepage control performance；Under described high-density polyethylene geomembrane layer 1
Side is provided with needle-punched geotextiles 3, described needle-punched geotextiles 3 for polyvinyl resin bar by thermoplastic, mold or be bonded in described highly dense
On degree polyethylene film for earthwork layer 1, so that needle-punched geotextiles embeds geomembrane.
Also being installed with two reinforcements on the surface of described needle-punched geotextiles 3, two described reinforcements interlock respectively
Being fixed on two diagonal of described needle-punched geotextiles 3, the center being prevented from needle-punched geotextiles 3 sinks and causes pin
Thorn geotextiles 3 deforms disengaging from geo membrane layers 1, improves the firmness of product.
The end lower surface of described needle-punched geotextiles has multiple longitudinal water guide groove, and described water guide groove ends is provided with drips
Water guide pillar, ponding is derived from water guide groove, finally drips from the guide pillar that drips, in time by between needle-punched geotextiles and geo membrane layers
Ponding discharge, in case needle-punched geotextiles depart from geo membrane layers, further increase the firmness of product.
In addition, the both sides of described geo membrane layers 1 and needle-punched geotextiles 3 are separated, form breach 4, thus can realize many
Block composite geo-membrane overlap joint coordinates, and overlap joint fitness is high, and easy construction and overall flexibility are good, and service life is long.
Being embedded with resin streak 5 at described breach 4, resin streak can increase composite earth in composite geo-membrane surrounding medium circle
Coefficient of friction between work film and surrounding medium interface, strengthens the frictional force between composite geo-membrane and surrounding medium, with surrounding
Medium forms stronger snap-in force, it is to avoid the phenomenon gliding occurs at side slope in engineering for the composite geo-membrane, improves each
The stability of class engineering.
