Problems solved by technology

[0002] The prior art of the present invention is that the patent No. is CN1100769, and the name of the invention is a geosynthetic earth pad and its manufacturing method of wire pinning. The laminates are connected by multiple nailing wires. The disadvantage is that when the clay pad is placed on a slope embankment with a certain slope, due to the action of gravity, the bentonite in the clay pad will move, causing the bentonite layer of the clay pad to move up and down. Unevenness, less upper part and more lower part, which affects the effect of clay pad to prevent liquid leakage
When in use, it is necessary to spread a geomembrane on the clay pad, and then lay a non-woven fabric on the geomembrane to achieve a satisfactory anti-seepage effect, which is very inconvenient to use

Embodiment Construction

[0008] refer to figure 1 , the geotechnical composite material consists of a layer of geomembrane (1), an upper layer of geotextile (2), a bentonite layer (3), and a lower layer of geotextile (4) from top to bottom. The upper surface of the upper geotextile (2) is composited with the geomembrane (1), and the lower surface of the upper geotextile (2) is coated with an adhesive to adhere to the lower surface of the bentonite layer (3) below it. The surface, the upper surface of the lower geotextile (4) is also coated with an adhesive to adhere to the lower surface of the bentonite layer (3) located thereon, by chemical bonding between the two layers of geotextiles (2), (4) ) between the bentonite layer (3) and the geomembrane (1) compounded with the upper geotextile (2), both of which prevent the leakage of liquid gas.

[0009] The manufacturing method of this geotechnical composite material is to first complete the high-temperature and high-pressure thermal compounding of the ...

Abstract

This invention relates to a soil mechanics compound material and its manufacturing method characterizing that the structure of the material is formed by one layer of soil mechanic film, an upper layer soil fabric, a layer of bentonite and lower layer soil fabric from top to the bottom. The bentonite is placed between the two soil fabrics by chemical adheres, the soil film is combined with the upper soil fabric. The method is first of all to finish the high temperature high pressure heat compound of the film and the upper soil fabric, then to coat adhesion agent and spread bentonite between the bottom surface of the upper fabric and the top surface of lower fabric then to be extruded to formation.
