Box catchment and earthing planting system and method for utilizing system to conduct reclamation on open-air pit

Abstract

The invention provides a box catchment and earthing planting system and a method for utilizing the system to conduct reclamation on an open-air pit. The box catchment and earthing planting system comprises a plurality of boxes which are communicated with each other and located in the mine pit, and the bottom shapes of the boxes are equal to the shape of the pit where the boxes are located; the tops of the boxes and the places, at a certain distance from the tops of the boxes, in the boxes are all provided with cover plates, and a plurality of water leaking holes are formed in the positions, opposite to the boxes, of the cover plates; the top of each cover plate is sequentially provided with geotextile, a filtration layer and an earthing planting layer from bottom to top; the box at the most outer side among the boxes is provided with a water inlet. The catchment and earthing planting system can solve the reclamation problem that in the the process of land reclamation, open-air mine pits, deep pits for soil mining and brick firing and waste pit ponds and ditches are difficult to reclaim because of scarce soil sources, the reconstruction of earth surface landscape is achieved, the cultivated area is effectively increased, and the microclimate of farmlands is improved.

Description

technical field [0001] The invention belongs to the fields of pit reclamation and water saving, and in particular relates to a planting system for collecting water in a box and covering it with soil and a method for reclamation of an open pit body using the system. Background technique [0002] In the process of land reclamation, for large-scale open pits, deep pits excavated and fired bricks, or abandoned pits and ditches, earthwork backfilling is generally used for reclamation. On the one hand, earth filling is limited by the soil source conditions, especially in plain areas where the soil source is relatively scarce, the cost of earth transportation is high, and it will also cause private digging and random mining, which will bring ecological damage; on the other hand, the pits and ponds covered with soil only have The planting function has lost the original geographical conditions of the pits and ponds, and the topographical advantages of the pits and ponds for water sto...
