In the earth rock hybrid dam, the earth rock dam is constructed on the rock foundation or pebble foundation with crack development by the dam construction materials that are not isolated to serve as the isolation between the dam body and the foundation; Isolation between gabion, sand bag or soil bag and thin foundation;
Geotextiles have high tensile strength and extensibility
Artificial earth filling, stone stacking, or isolation layer between material yard and foundation, and earth rock dumping and filling in water (river, river, lake, sea) that is not suitable for the isolation between frozen soil layers, and placing geotextile under the water can play the role of isolation, filtration and reinforcement. It can exchange ancient engineering materials and construction ideas, make construction safer, and help to protect the situation, and can be more economical and effective, Durable solution is basically very important in engineering construction. The geotextile has raised mechanical function, good water permeability, isolation, serenity and enhancement functions The bottom layer that can be acclimated to uneven surface can resist the external force of construction, and can still adhere to the original function under long-term load Features of impervious geotextile: good aging resistance, large temperature range, high puncture resistance and large friction coefficient. It is suitable for water conservancy, chemical engineering, construction, transportation, subway, tunnel, garbage disposal and punishment site and other projects. Excellent anti-drainage function impervious geotextile main effects:
It has high tensile strength and extensibility through needling or hot bonding forming. When it is combined with plastic film, it not only increases the tensile strength and puncture resistance of plastic film, but also increases the friction coefficient of the battle surface due to the rough surface of non-woven fabric, which is conducive to the stability of composite geomembrane and protective layer
