Abstract

The invention discloses a production and construction project soil profile pattern and an improving method thereof. The production and construction project soil profile pattern sequentially comprisesa surface soil layer, a rock scrap layer, a gravel layer and bed rocks from top to bottom, the thickness of the surface soil layer is 10-90cm, the thickness of the rock scrap layer is 40-70cm, and thethickness of the gravel layer is larger than 20cm. According to the improving method, loose deposition objects of the production and construction project are divided into gravels, rock scraps and soil, and the gravel layer, the rock scrap layer and the surface soil layer are sequentially stacked on the bed rocks according to types of plants to be recovered to form the soil profile pattern suitable for plant growth. According to the method, site conditions of vegetations in a production and construction project area can be effectively kept, quick recovery of the vegetations can be facilitated,recovery effect and stability in the vegetations in the production and construction project area are improved, and the soil and water conservation effect of the vegetations is exerted as soon as possible.

Description

technical field [0001] The invention relates to the field of water and soil conservation, in particular to a soil configuration for production and construction projects and an improvement method thereof. Background technique [0002] With the development of society, production and construction projects have been increasing, resulting in a large number of loose accumulations. The loose accumulations produced by production and construction projects have the characteristics of loose soil, complex ground composition and steep accumulation surface. Because these loose accumulations lose their original soil structure, the vegetation is not easy to grow and presents a bare state, which is prone to serious man-made soil erosion. The specific manifestations are as follows: on the one hand, when the deposits are piled up, soil and rock materials are mixed, the pores are distributed unevenly, and the water retention performance is poor, which is not conducive to the growth of vegetati...
