Composite Geomembrane-Composite membrane

1．Brief introduction composite geomembrane:

With impermeable geomembrane production line. Sprinkling method used with the latest technology, can produce a cloth one film, one cloth and a film, a film and many cloth, many cloth and many film in line with the specifications of a variety of film geomembrane (basically using needle puncture geotextile, and also can use filament weaving fabric, plastic woven fabric). The production process of geotextile fabric has managed to maintain the good mechanical properties of geotextile, also make the product confirm the uniformity of film product, high peel strength, and avoid the form of stomata l and sandstone in the membrane, greatly enhance the impermeability ability. The surface of the film use embossing treatment enhances the coefficient of friction of product, not only raise the steady of project, and also make construction more convenient.
After detection by Nanjing Water Academy of Sciences Geo Department, Textile Institute of Science and Technology, The width of our product is 1.0meter to 6.0meter; annual output is 9,000,000 square meters.
（1） how to use Base fabric：
The Company’s production in line with the main geomembrane to acupuncture as a geotextile fabric can also be based on user requests the production of weaving machines, plastic composite products.

2 Product specification：
（1）one cloth and one film：      Base fabric： 100—1000 g / m2
                                                 Membrane thickness0.1—1.5 mm
（2）two cloth and one film ：     Base fabric： 80—600 g / m2
                                                 Membrane thickness： 0.2—1.5mm
（3） one cloth and two film ：Base fabric： 100—1000 g / m2
                                                 Membrane thickness： 0.1—0.8 mm

3 Feature and usage of composite membrane：
As a result of use of geotextile composite geomembrane (weaving machines or plastic woven cloth) for fabric, it has a geotextile In addition to isolation, drainage, reinforcement, protection, and other things have also closed (anti-) function can be widely used and Water dams, roads, airports, water, housing, environmental protection, and many other fields in engineering from the main anti-business, protection, strengthening the role and so on.

4Usage of Composite membrane：

（1）River bank：
Road along the river and road covered with water should be used complex earth film and complex earth film with reinforcing bars to protect the slope along the river.

（2）Karst reign roadbed：
In designing should be paid more attention, then take the measurements to head off and separate. Set up swash-proof and leakage proof.

（3）Long-time ice road：
Drainage system should be established far away from the foot of the slope to prevent the water flow and leakage influencing the changes of the ice-road upper limit. Removing the underneath water will take away the underneath water which can probable form drumlin. When granule earth is used to build the road dike, the foot of the road dike should be set up with thin water partition to prevent the underneath water from gathering up to the road dike

（4）Road in swelling earth area：
For the road part of strong swelling earth and medium swelling earth in high way, the road should be designed as that kind of water proofing, heat preservation, and wind proof. No leakage floor in the central separation area.

5. Drainage, waterproof and leakage proof in salty area：

 To prevent the ice swelling, salt swelling in salty area, thin water partition should be set up, 40-50cm thick. Anti-filtration should be established on the top of it and at the foot of it; fabric of leakage proof can also be used such as be used such as complex earth film and complex earth film with reinforcing bar.
