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] Select 20% of the red-bed sandstone rocks produced by slope excavation, and select 80% of the red-bed mudstone rocks nearby, crush and mix them with a crusher and pass through a 2cm sieve to prepare crushed rocks for later use. The natural air-dried silkworm dung with a water content of 15% is mixed with industrial tannin, industrial citric acid, industrial humic acid, industrial zeolite powder, industrial diatomaceous earth powder, and industrial bentonite in a weight ratio of 15:2: The ratio of 3:45:10:10:15 is mixed evenly to prepare a mixture containing silkworm excrement for later use. The weight percentage of the components is respectively 60% crushed rock, 5% silkworm manure-containing mixture, 20% peat, 1% rice straw cut into ≤3cm, 5% chicken manure with a water content of 15%, 6 % of pig manure with a water content of 15%, 1% cement, 0.05% sodium lignosulfonate, 0.16% polyacrylamide, 0.2% borax, 0.03% amino acid chelated zinc, 0.05% amino acid chelated Iron, 0...

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 procedures of the present invention, and the artificial soil for red bed sandstone slope wounds of the present invention is still prepared in the same way.

Abstract

The invention provides a redbed sandstone 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, cement, lignosulfonate, high water-absorbent resin and fertilizer which are effectively mixed under certain conditions. The preparation method has significant effects in speeding up the formation of redbed sandstone 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 artificial soil, in particular to a preparation method of artificial soil for red bed sandstone slope wound. Background technique [0002] The topography of my country's red-bed areas is relatively undulating, and construction of roads, hydropower, and mines often requires the excavation of a large number of slopes, resulting in many exposed red-bed sandstone slopes, and the resulting soil erosion and ecological damage are very serious. Red bed sandstone is a sedimentary clastic rock in which clastic components such as quartz and feldspar account for more than 50%. Debris etc. Red bed sandstone mainly has two typical structural forms: granular clastic structure and muddy cemented structure, and its strength varies greatly due to differences in cementing materials and weathering degrees. After the red sandstone is excavated or blasted out, it is wetted by water or subjected to the dry-wet cycle in the atmospheric environment. ...
