The technical scheme of the utility model is as follows:
the utility model provides an utilize kind of grass to implement restoration structure that mining area was administered, includes that the interval digs the drainage channel of establishing and plants the hole on the mining area soil, plant the hole inner wall and all lay the mining area rubble, just semi-permeable membrane and living beings charcoal layer are laid in proper order to mining area rubble upper strata the sludge blanket is laid to the space bottom that living beings charcoal layer encloses, humus layer is laid to the sludge blanket upper strata, plant the turf on the humus layer, just the turf both sides adopt the stake to fix.
Further, the turf is one or more of zoysia japonica, paspalum natatum, festuca arundinacea, trefoil alba, trefoil rubra, festuca arundinacea, bluegrass, glume clavatum, bermuda grass, dichondra repens and alfalfa.
Furthermore, the semi-permeable membrane is made of degradable materials, and the degradation period is more than 1 year.
Further, the sludge layer is obtained from municipal sludge or construction excavation sludge.
Furthermore, the cross sections of the planting pits and the drainage channels are isosceles trapezoids.
The utility model has the advantages that:
the utility model has the advantages that the applicability is strong, the success rate of repairing the soil in the mining area with severe soil quality and environment is higher, the broken stones in the mining area are laid at the bottom, namely, the broken stones screened in the soil leveling process of the mining area are solved, meanwhile, the broken stones have high water permeability, the water can be quickly infiltrated in the rainy day, the situation that the growth of the turf is influenced by dissolving too much salt and the like is avoided, meanwhile, the dissolved salt in the soil in the mining area is prevented from permeating into the planting pits through the capillary action, and the semi-permeable membrane is used for the natural communication of the water, so that the situation that the nutrient in the planting pits is not leaked, the external high salt does not enter, and the water can be naturally communicated is ensured; the biomass charcoal layer has the function of eliminating the side effect of the semi-permeable membrane, and due to the high salt content outside, when rainwater is abundant, moisture can permeate outwards under the action of osmotic pressure, and the biomass charcoal layer can absorb enough moisture, so that a certain amount of moisture is kept in the planting pits, and the sludge layer not only supplements a healthy growth substrate, but also carries out harmless treatment on municipal sludge and the like; along with the growth of the turf, the root of the turf is gradually developed, the adaptability and the resistance are increased, the semi-permeable membrane can be gradually penetrated by the root system, the planting pit and the land of the mining area are integrated, and the land of the mining area is treated.
