Engineering sand treatment method

Abstract

The invention provides a method of engineering sand treatment which contains the following steps: delimitation: classify the tires based on their sizes. Paving: according to the delimitation result, arrange the tires on the subsequence that the large on front and the small on back in the desertification land. Array several cross beams on the upwind direction and several vertical beams on the tailwind direction. Sow desert biological seeds in the block sand barrier formed by the cross and vertical beams. The invention makes use of waste tires for engineering sand treatment on the desertification land by rational paving. With the attributes of corrosion resistance, weathering resistance and high-temperature resistance, each tire can be used for many times. It can reduce the treatment cost, enlarge the treatment scale and reduce the environmental pollution and its degree of the increasing waste tires caused by the social advance especially in the developed areas.

Description

technical field [0001] The invention relates to engineering sand control, in particular to an engineering sand control method using waste tires to fix quicksand. Background technique [0002] Existing measures to control desertification and desertified land include biological sand control, engineering sand control, chemical sand control and so on. Their common purpose is to fix sand and dust and build artificial biological vegetation on desertified land to effectively suppress the occurrence frequency and degree of damage of sandstorms, especially to prevent and restrain the development trend of land desertification, and then achieve the control of desertified land. [0003] The existing sand control measures in the project use semi-concealed grass square sand barriers, clay sand barriers, gravel sand barriers, etc. However, due to the shortage of raw materials of wheat straw in the edge of the desert and its easy decay, the grass grid Sand control measures cannot be carrie...

AI Technical Summary

Problems solved by technology

[0003] The existing sand control measures in the project use semi-concealed grass square sand barriers, clay sand barriers, gravel sand barriers, etc. However, due to the shortage of raw materials of wheat straw in the edge of the desert and its easy decay, the grass square Sand control measures cannot be carried out on a large scale

However, clay sand barriers and gravel sand barriers are restricted by the surface thickness of the sand layer and require a large amount of labor, making it difficult to expand the scope of treatment;

[0004] For chemical sand control measures, the progress of sand control projects is inhibited due to high cost, high spraying requirements, and intolerance to livestock trampling.
