Magnetic attraction type sandy soil remediation method

Abstract

The invention discloses a magnetic attraction type sandy soil remediation method, and belongs to the technical field of soil governing. According to the magnetic attraction type sandy soil remediation method, a plurality of embedded balls are evenly embedded into soil firstly, then composite scales are pressed in a wrapping mode through remediation liquid, and when the composite scales are pressed to permeate into the soil along with the remediation liquid, the composite scales approach the embedded balls, under the magnetic attraction effect of the pre-buried ball on the press-fit composite scales, the press-fit composite scales extrude the pre-buried ball through soil, meanwhile, moisture in the repairing liquid is also in contact with the pre-buried ball, and the pre-buried ball and the soil jointly trigger the action that the pre-buried ball releases auxiliary bonding fibers and heat; the heat is used for heating the press-fit composite scales to enable the press-fit composite scales to disintegrate and release the plant adhesive to act between the soil, meanwhile, the magnetic attraction effect of the embedded balls on the press-fit composite scales is enhanced, the soil, the plant adhesive and the auxiliary adhesive fibers are mixed at the moment, extrusion force is applied to a local area through the press-fit composite scales, and thus the bonding effect on the sandy soil is obviously improved.

Description

technical field [0001] The invention relates to the technical field of soil treatment, in particular to a magnetic suction type sandy soil restoration method. Background technique [0002] At present, climate warming and precipitation reduction have exacerbated the aridification of climate and soil in Northwest China. This reduces the vegetation coverage in this area, and the soil structure becomes looser, which accelerates the desertification of the land. In addition, the warming of the climate and the continuous drought of the large-scale climate have seriously affected various water resources (glaciers, lakes, rivers, etc.), causing glaciers to retreat, rivers to reduce or stop flowing, lakes to shrink, and groundwater levels to drop. A large area of ​​vegetation died due to lack of water, which lost the function of protecting the surface soil and accelerated the speed of soil desertification. [0003] Soil desertification is defined as land degradation in arid, semi-ar...

Problems solved by technology

[0005] In fact, there is a "universal binding constraint" between soil particles. This constraint allows the soil to allow plant roots to grow inside it, and to retain water, fertilizer, and ventilation, while sand particles do not have such constraints. Therefore, conventional methods It is difficult to fundamentally solve the problem of sandy soil
