AI Technical Summary
Due to their loose structure and high permeability, spoil heaps cause soil erosion and geological disasters such as landslides. Existing reclamation measures lack coordination, increase engineering costs and construction difficulties, and result in poor vegetation restoration.
The system adopts an integrated structure consisting of an impermeable layer, a gravel drainage layer, a water collection pipe, and a vegetation protection frame. The impermeable layer uses biodegradable non-woven fabric, the gravel drainage layer is equipped with a water collection pipe, and the vegetation protection frame is a trapezoid with a wider top and a narrower bottom. Combined with anchoring trenches for fixation, it forms an integrated system of impermeability, drainage, and vegetation restoration.
It effectively prevents water infiltration, reduces soil erosion and landslide risks, ensures safety and stability, guarantees vegetation growth, reduces engineering costs, and improves vegetation survival rate and reclamation effect.
