Description
Technical field
The utility model is related to the geotechnological technical field of membrane of construction material, and in particular to a kind of civil engineering is geotechnological with many structures
Film.
Background technology
Geomembrane is using plastic sheeting as antiseepage base material, with non-woven fabric compounded seepage by geo-textile material, new material soil
Its barrier performance of work film depends primarily on the barrier performance of plastic sheeting.At present, the plastic sheeting of domestic and international antiseepage application, main
Have in polyvinyl chloride (PVC) and polyethylene (PE), EVA (ethylene/vinyl acetate copolymer), tunnel applications and also have design to use
ECB's (geomembrane is blended in ethylene vinyl acetate modified pitch), they are a kind of polymer chemistry flexible materials, and proportion is smaller,
Extensibility is stronger, and adaptive deformation ability is high, corrosion-resistant, low temperature resistant, good frost resistance.
For existing geomembrane, its structure is generally multiple field mechanism, because although existing geomembrane has very well
Anti-permeability, but overall intensity is not high, very easy situation about rupturing occur, under this reason, existing geomembrane
Mostly sandwich construction, due to being layered on earth's surface geomembrane, due to reasons such as geological movements, geomembrane, which is in be stretched always, to be torn more
During, due to existing geomembrane, reproducibility itself is poor, therefore easily geomembrane fracture occurs, so that overall
Anti-permeability is had a greatly reduced quality.
The content of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of civil engineering with many knots
Structure geomembrane, is integrally not susceptible to fracture, and impermeable effect is outstanding.
To achieve the above object, the utility model provides following technical scheme：
It is coated with a kind of civil engineering many structure geomembranes, including geomembrane matrix 1, the bottom surface of geomembrane matrix 1
Lower geotechnological layer of cloth 3 is bonded with primer layer 2, the bottom surface of primer layer 2, the upper surface of geomembrane matrix 1 is coated with mesoglea 4, in
The upper surface of glue-line 4 is bonded with middle geotechnological layer of cloth 5, and the upper surface of middle geotechnological layer of cloth 5 is equipped with nylon yarn screen cloth 6, nylon mesh
The upper surface of cloth 6 is equipped with geotechnological layer of cloth 7.
Integrally connected with nylon yarn screen cloth 6 by the form of gluing between described middle geotechnological layer of cloth 5 and upper geotechnological layer of cloth 7
Connect.
Described lower geotechnological layer of cloth 3, middle geotechnological layer of cloth 5, upper geotechnological layer of cloth 7 are made of polyester filament geotextiles.
Described primer layer 2 and mesoglea 4 are made of propylene glue.
Described geomembrane matrix 1 is made of PVC materials.
Compared with prior art, the beneficial effects of the utility model are：It can increase overall strong using nylon yarn screen cloth 6
Degree and anti-pull performance, for by ground stress deformation, are integrally not easy to situation about being broken, therefore overall anti-
Osmotic effect is outstanding.
Brief description of the drawings
Fig. 1 is schematic cross-section of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
