Examples
Embodiment 1
[0020] Breathable anti-seepage blanket structure ( figure 1 ): The bottom layer is geotextile 1 and the upper layer is sand and binder mixture 2. The thickness of the mixture layer was 2 mm.
[0021] The sand is sieved to obtain sand with a particle size of 100-200 mesh.
[0022] Preparation: Lay the geotextile 1 flat, evenly coat the adhesive (polyurethane strong adhesive, Yantai Wanhua,) 0.1-0.2mm, then evenly spread the sand 1, and leave it for 24 hours to obtain a cured product.
[0023] The prepared air-permeable anti-seepage blanket can be bent continuously at 120° (bending to an included angle of 30°), and has good flexibility and good anti-seepage function. Because it is lined with geotextiles, it can be transported over long distances and has better strength.
Embodiment 2
[0025] Breathable anti-seepage blanket structure: the bottom layer is a geomembrane, and the upper layer is a mixture of sand and binder 2. The thickness of the mixture layer was 1.5 mm.
[0026] The sand is sieved to obtain sand with a particle size of 100-200 mesh.
[0027] Preparation: Lay the geomembrane flat, evenly apply adhesive (DuPont TPE, thermoplastic elastomer) 0.1-0.2mm, and then lay sand. Place the cured product for 24 hours.
[0028] The prepared air-permeable anti-seepage blanket can be bent continuously at 120° (bending to an included angle of 30°), and has good flexibility and good anti-seepage function.
experiment example
[0030] The experiment site is artificially reclaimed Haimeng saline-alkali land in Caofeidian.
[0031] Dig ditches evenly in the plot, the ditch width is 40cm, the ditch depth is 40cm, and the ditch spacing is 6m. There is no requirement for the flatness of the bottom of the ditch. Lay the air-permeable anti-seepage blanket of embodiment 1 on the bottom of the ditch, and lay plastic film on the side of the ditch. Place plant seeds in the ditch, including 20g of rye, 30g of Amorpha fruticosa, and 30g of Vitex twigs. Put in soil and sprinkle with water.
[0032] After 3 months of implementation, the comprehensive emergence rate of plant seeds has reached more than 80%. After a year of growth, the vegetation coverage of the site has reached more than 75%.
