Geomembrane with impermeable plastic film as a substrate, and non-woven geotextile composite made of impermeable material, its performance depends on impervious impermeable plastic film performance. At present, the application of impermeable plastic film at home and abroad, mainly polyvinyl chloride (PVC) and polyethylene (PE), EVA (ethylene / vinyl acetate copolymer), also designed to use the tunnel applications ECB (ethylene-vinyl-modified bitumen blend geomembrane), which is a flexible material polymer chemistry, the proportion of small, strong extension quality waterproof geomembrane to adapt to high deformation, corrosion resistance, low temperature, frost performance. EVA geomembrane is one of geomembrane products, EVA namely ethylene - vinyl acetate copolymer, with good flexibility, flexibility, flexibility, weather resistance, resistance to environmental stress cracking resistance and adhesive properties, the mechanical indicators higher than ordinary polyethylene, because it also has a strong flexibility, so very convenient in construction, welding effect is very good. Products are widely used: the difficult lining subway, basement seepage and other projects, product standards "GB / T17643-1998" GL-2 based. Planted roof drainage board materials and plastic drain major equipment: (1) plastic drain (each batch using HDPE plastic drainage board shall be subject to inspection specified inspection department, and with factory certification and planted roof drainage board test Inspection reports should be used with regular checks of the film coat plastic drainage board is intact). Graded gravel should be weak weathered sandstone processing waterproof geomembrane direct, clay content should not exceed 5%, and remove impurities, plants, graded gravel particle size control: maximum particle size no larger than 5cm by 16mm quality mesh percentage of not less than 85% waterproof geomembrane 0.3mm sieve through mass percentage shall not exceed 20%. (2) applied to the drainage board to play a major construction machinery set up to fight plastic drain device has two forms: one for crawler piling machine wholesale waterproof geomembrane, one for the gantry flapper machine (with a guide). Require energy into the design depth of the static type or vibrating equipment is unavailable or flush hammer. Cannula insertion rod is flat or round, diameter greater than the size of the drainage board, drainage board design is longer than the length of the play set in the protection of the drainage board is not damaged. Also available crane hammers change working device and simple flapper machine.
