Description
Technical field
The utility model relates to geotechnics fields, more particularly, to a kind of bentonite waterproof blanket.
Background technique
Currently, sodium-based bentonite waterproof carpet is as a kind of novel environment friendly ecological anti-seepage material, with its unique leakproof
It can be used widely in the civil engineerings such as water conservancy, environmental protection, traffic, railway, civil aviaton.The based process of refuse landfill and
It binds, the antiseepage of man-made lake, reservoir, channel, river, roof garden, the names class such as basement, subway, tunnel, underpass underground
The antiseepage of building.But current most of waterproof blanket waterproof performances and not up to some strength are easy to absorb in the construction process
It is unexpected that water lower the waterproof blanket service life.Rainwater and underground water increase because waterproof blanket expansion is made the hydration reaction that causes of waterproof blanket
At the pressure loss, reduce the waterproof effect of waterproof blanket, and be not suitable for strong acid, strong basicity antiseepage.
Utility model content
In order to overcome above-mentioned existing issue, the utility model provides a kind of waterproof, good seepage-proof property, with long service life
Bentonite waterproof blanket.
The technical solution of the utility model are as follows: a kind of bentonite waterproof blanket, including the braiding soil set gradually from bottom to up
Work layer of cloth, Na-bentonite soil layer, non-woven geotechnical cloth layer and anti-seepage geomembrane layer, the braided geotextile layer dip-coating have waterproof painting
Layer, the anti-seepage geomembrane layer includes the first barrier plastic film layer, enhancement layer and the second antiseepage set gradually from the bottom up
Plastic film layers, the second barrier plastic film layer top are provided with elastic waterproof layer.
Pass through bonding between the braided geotextile layer, Na-bentonite soil layer, non-woven geotechnical cloth layer and anti-seepage geomembrane layer
Connection.
The braided geotextile layer using be mutually perpendicular to intersect as synthetic fibers and cotton fiber it is blended made of weave geotechnique
Cloth, tensile strength are high.
The waterproof coating is polymer cement waterproof coating.
The elastic waterproof layer is made of thermoplasticity elastic body water-proof substance.
First impervious barrier and the second impervious barrier are density polyethylene film with high layer.
The enhancement layer is network rubber piece, effectively improves the stretching resistance of the first impervious barrier and the second impervious barrier, is extended anti-
The service life of water blanket.
The utility model has the following beneficial effects: the bentonite waterproof blanket of the utility model, has waterproof painting by using dip-coating
The braided geotextile layer of layer and the anti-seepage geomembrane being made of elastic waterproof layer, two layers of barrier plastic film layer and enhancement layer
Layer, greatly strengthens the structural strength and waterproof, antiseepage, tension resistance performance of bentonite waterproof blanket, and strong alkali-acid resistance uses
Service life is long.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure, 1, braided geotextile layer；2, Na-bentonite soil layer；3, non-woven geotechnical cloth layer；4, the first barrier plastic film
Layer；5, enhancement layer；6, the second barrier plastic film layer；7, elastic waterproof layer；11, waterproof layer.
Specific embodiment
The utility model is further elaborated with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of bentonite waterproof blanket, braided geotextile layer, sodium base including setting gradually from bottom to up are swollen
Moisten soil layer, non-woven geotechnical cloth layer and anti-seepage geomembrane layer, braided geotextile layer, Na-bentonite soil layer, non-woven geotechnical cloth layer and anti-
It seeps between geo membrane layers through bonding connection
Braided geotextile layer using be mutually perpendicular to intersect as synthetic fibers and cotton fiber it is blended made of braided geotextile, resist
Tensile strength is high, and braided geotextile layer dip-coating has waterproof coating, and waterproof coating is preferably polymer cement waterproof coating, it is by a variety of
The lotion of waterborne polymeric synthesis is formed with the high grade cement mixed with various additives, flexibility and the cement of polymer (resin)
Rigidity becames one, so that it is excellent in terms of impermeability is with stability, waterproof, seepage control effect is good and acid and alkali-resistance.
Anti-seepage geomembrane layer includes the first barrier plastic film layer, enhancement layer and the second antiseepage set gradually from the bottom up
Plastic film layers, the second barrier plastic film layer top are provided with elastic waterproof layer, and first impervious barrier and second prevent
Infiltration layer is density polyethylene film with high layer, and enhancement layer is network rubber piece, effectively improves the first impervious barrier and the second impervious barrier
Tension resistance performance, extend the service life of waterproof blanket, elastic waterproof layer is made of thermoplasticity elastic body water-proof substance, be people
Make rubber or synthetic rubber, waterproof, seepage control performance is good and tension resistance.
The above, the only preferred embodiment of the utility model, are not intended to limit the utility model, all according to this
The technical spirit of utility model any trickle amendment, equivalent replacement and improvement to the above embodiments should be included in this
In the protection scope of utility model technical solution.
