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.

Usage of Composite membrane

1River 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.

2Karst 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.

3Long-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

4Road 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.
