Problems solved by technology

Artificial soil is an important material basis in ecological slope protection engineering, but currently known artificial soil needs to add a large amount of mature soil taken from local cultivated land, which not only causes the destruction of limited soil resources, but also greatly increases the construction cost

Embodiment 1

[0011] The red bed sand-mudstone interbedded rock produced by excavation of the side slope is selected from 30% sandstone and 70% mudstone, crushed with a crusher and passed through a 2cm sieve to obtain crushed rock for future use. Silkworm manure with a water content of 15% after natural air drying, and industrial ferrous chloride, industrial calcium hydroxide, industrial humic acid, industrial kaolin, and agricultural plant ash by weight 10:5:10:55:15 The ratio of : 5 is uniformly mixed to prepare a mixture containing silkworm excrement for subsequent use. Get component weight percentage and be respectively 40% crushed rock, 2% silkworm manure-containing mixture, 40% peat, 1.5% rice straw cut into ≤3cm, 5% chicken manure with a moisture content of 15%, 10 % of pig manure with a moisture content of 15%, 0.1% sodium polyacrylate, 0.3% attapulgite powder, 0.05% polyvinyl acetate, 0.15% borax, 0.08% zinc sulfate, 0.06% ferrous sulfate, 0.01% ammonium molybdate, 0.02% copper su...

Embodiment 2

[0013] The operating procedure was the same as in Example 1 during preparation. Only the type, quantity, specification, and water content of the raw materials are changed within the scope specified by the operating procedure of the present invention, and the artificial soil for red bed sand-shale interbedded slope wounds of the present invention is still prepared in the same way.

Abstract

The invention provides a redbed sand-shale interbedded slope raw surface artificial soil preparation method, which prepares the artificial soil with raw material components including redbed sandstone rock, redbed shale rock, compound containing silkworm excrement and / or wormcast and / or algae residue, peat, straw, livestock and poultry manure, high water-absorbent resin, attapulgite powder, polyvinyl acetate and fertilizer which are effectively mixed under certain conditions. The preparation method has significant effects in speeding up the formation of redbed sand-shale interbedded slope raw surface artificial soil aggregate structure, increasing the water and fertilizer-keeping performances of the soil, improving the physical and chemical properties of the soil and promoting the plant growth and development.

Description

technical field [0001] The invention relates to an artificial soil, in particular to a method for preparing an artificial soil for a red bed sand-shale interbedded slope wound. Background technique [0002] The topography of my country's red-bed areas is relatively undulating, and roads, hydropower, mines and other engineering constructions often have to excavate a large number of slopes, resulting in many exposed red-bed sandy-mudstone interbedded slopes. The resulting soil erosion and ecological damage are very serious. serious. The lithology of the red bed sand-mudstone interbed is that mudstone and sandstone are soft and hard. The sandstone is generally hard in texture, has high uniaxial compressive strength and strong water resistance, and is the supporting framework in the slope. The mudstone in the red sand-mudstone interbed is generally formed by suspended sedimentation of silt and fine sand and clay. The degree of diagenesis is not high and the texture is weak. tim...
