Description
Technical field
Waterproof material technical field is the utility model is related to, more particularly to a kind of pitch-geomembrane composite anti-penetrating material.
Background technology
At present, impervious material is widely used in the every field of China's infrastructure construction, especially in hydraulic engineering.
In order to prevent earth and rockfill dam in hydraulic engineering, rock-fill dams etc. from revealing, it is proposed that many impervious materials, such as geomembrane, two
The composite geo-membrane of the compositions such as the film of cloth one, such material effectively can prevent dam body from revealing, but there is also many shortcomings, example
Phenomena such as being easily destroyed such as relatively low, easy to aging, the geotechnological membrane body of tensile strength, the longevity is effectively used so as to shorten impervious material
Life, so the impervious material in existing hydraulic engineering still has many aspects to need to be improved.
The content of the invention
In order to overcome the various deficiencies in above-mentioned existing hydraulic engineering present in impervious material, the purpose of this utility model exists
It is simple in construction, tensile strength is high, non-deformability is strong and can effectively prolong in providing a kind of pitch-geomembrane composite anti-penetrating material
Long life.
To achieve these goals, the technical solution of the utility model is realized in：
A kind of pitch-geomembrane composite anti-penetrating material, including non-woven geotechnical cloth layer 1, the top of non-woven geotechnical cloth layer 1 laying the
One high-density polyethylene geomembrane 2, the top of the first high-density polyethylene geomembrane 2 are equipped with the first fiberglass gridding cloth 4,
The top of first fiberglass gridding cloth 4 is equipped with the second high-density polyethylene geomembrane 3, the second high-density polyethylene geomembrane 3
Top is equipped with the second fiberglass gridding cloth 5, and the top of the second fiberglass gridding cloth 5 is equipped with SBS modified asphalt layers 6.
Described non-woven geotextile 1 is 200-300g/m2。
Described the first high-density polyethylene geomembrane 2 and the thickness of the second high-density polyethylene geomembrane 3 be 0.3-
0.5mm。
Described the first fiberglass gridding cloth 4 and the second fiberglass gridding cloth 5 is 100-160g/m2。
The described thickness of SBS modified asphalt layers 6 is 2-3mm.
The first described high-density polyethylene geomembrane 2 and the first fiberglass gridding cloth 4, the second high density polyethylene (HDPE) soil
The fiberglass gridding cloth 4 of work film 3 and first is bonded using polyurethane adhesive.
The beneficial effect that the utility model can reach：
(1) inside configuration interval attachment layer glass fibrous mesh cloth, the tensile strength and resistance of the material can be strengthened
Shape ability, there is facilitation for improving the materials'use life-span.
(2) material uses twice geomembrane as antiseepage body, with reference to outermost SBS modified asphalt layers, it is possible to increase
Material anti-seepage effect.Non-woven geotextile can prevent geomembrane is pierced to destroy.
