Description

Utilize biological algae agent to prepare the method for red-layer sand slime stone interbeded slope wounded surface artificial soil

?

Technical field

The present invention relates to artificial soil, be meant especially and a kind ofly utilize biological algae agent to prepare the method for red-layer sand slime stone interbeded slope wounded surface artificial soil.

Background technology

The red beds of China mainly is distributed in the wide geographic area of southwest, south China, Central China and northwest, in engineering constructions such as the geographic constructing road of China's red beds, hydroelectric development, mining, because of slope excavation has caused a lot of exposed red beds sand shale alternating layers side slopes.The lithology of red beds sand shale alternating layers is that mud stone and sandstone soft and hard alternation distribute, and a little less than the mud stone weathering resistance ability, sandstone weathering resistance ability is strong, and the thin layers of mudstone between the sandstone easily forms the argillization interlayer.Sandstone in the red beds sand shale alternating layers is the support frame in the sloping body, and general quality is hard, uniaxial compressive strength is high, water repelling property is strong.Mud stone in the red beds sand shale alternating layers is generally suspended to deposit by powder fine sand and clay and forms, and diagenetic grade is not high, the quality weakness, certain swelling property is arranged, and bearing capacity is lower, compares with sandstone, mud stone not only uniaxial compressive strength is not high, and dried wet compressive strength differs several times to tens times.Artificial soil is the important substance basis in the red beds rock slope surface of a wound ecological revetment engineering, adopt artificial soil on the red beds rock slope surface of a wound, to implement the ecological protection measure of artificial soil moved in to improve the original, culturing plants, the good result of can play stable side slope, conserve water and soil, beautifying the environment (as Chinese patent ZL200810046488.6).The scope that soil algae distributes is extremely wide, and not tight to the envrionment conditions requirement, adaptability is stronger.Soil algae is a photo-autotroph, is organic manufacturing and supplier.The organism ratio that soil algae forms is easier to decompose, and can promote the procreation of nutrient circulation and microorganism, and the formation of soil and the raising of soil fertility are had promoter action.Yet, because of biological algae agent does not obtain rational Application, cause the repairing effect of red-layer sand slime stone interbeded slope wounded surface artificial soil not ideal enough in the present known artificial soil process for preparation.

Summary of the invention

The object of the present invention is to provide and a kind ofly utilize biological algae agent to prepare the method for red-layer sand slime stone interbeded slope wounded surface artificial soil, to overcome the deficiency that prior art exists, have technology simple, draw materials conveniently, characteristics such as with low cost, perfect in shape and function, to circulation, the supply that increases the available nutrient of soil of quickening soil nutrient elements, improve soil physico-chemical characteristic, promote that Revegetation has significant effect.

The objective of the invention is to realize by the following technical solutions, the method for utilizing biological algae agent to prepare red-layer sand slime stone interbeded slope wounded surface artificial soil is carried out according to following steps:
