Abstract
The invention discloses a soil stabilizer, which is used for overcoming the defects of an existing soil stabilizer that soil is loose after being immersed by rainwater, the pavement easily generates pot holes after being crushed, and the soil stabilizer is not suitable for a region with much rainwater. The soil stabilizer disclosed by the invention is prepared from water, dilute sulphuric acid, dodecylbenzene sulfonic acid, polyacrylamide, magnesium oxide, calcium phosphate, sodium silicate, sodium lignin sulfonate and polyvinylpyrrolidone. According to the soil stabilizer disclosed by the invention, the hydrophilicity of soil can be reduced; the filtration coefficient is reduced after crushing; and the formed solid particles are solidified, so that the destroy to a roadbed caused by water is reduced, the frost boiling phenomenon is effectively prevented, and the carrying capacity of the pavement is improved.
Description
Technical field
The present invention relates to the soil curing agent of a kind of soil curing method making roadbed or pavement usage.
Background technology
In prior art, building the road, in the engineering such as water conservancy, ramp be firm, need that the mud river soil surface softer to quality is cured, hardening treatment.In known roadbed treatment technology, the most traditional method rolls after being add a certain proportion of unslaked lime and mixing with soil in soil, this method not only causes severe contamination to environment but also is difficult to obtain high-quality solidification treatment in construction process, though there is the tackiness agent using other materials replacement unslaked lime as roadbed treatment and soil stabilizer, such as patent ZL02114518.0 soil stabilizer, it is C with alkyl
10-C
14alkyl benzene sulphonate (ABS), the pH value that dilute sulphuric acid and neutral water glass are prepared in water maintains the uniform liquid of about 2-3, and their weight ratio is alkyl is C
10-C
14alkyl benzene sulphonate (ABS) 100, water 300-500, dilute sulphuric acid 0.5-3, neutral water glass 1-12.
But the method exists roadbed looseness of soil after rainwater floods, after rolling, cause road surface to occur the scenes such as hollow, be not suitable for the shortcoming that rainwater more regions uses.
Summary of the invention
The present invention is for solving prior art Problems existing, and a kind of soil curing agent is provided, join after mixing with water in soil, the character of soil can be changed, soil particle is after charge effect and ion-exchange, spoiled soil adsorbed film of water, moisture content in soil is easily discharged, after using this soil-solidified-agent, the wetting ability of soil reduces, after rolling, permeability coefficient declines, formed soil particle between consolidation get up, thus reduce water to the destruction of roadbed and effectively prevent burst and become muddy when a thaw sets in phenomenon, raising way supporting capacity.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of soil curing agent, is characterized in that: be made up of following raw material,
Witco 1298 Soft Acid 50-55 parts
Dilute sulphuric acid 0.8-2 parts
Polyacrylamide 10-15 parts
20-30 parts, magnesium oxide
17-20 parts, calcium phosphate
Water glass 2-3 parts
Sodium lignosulfonate 0.2-0.5 part
Polyvinylpyrrolidone 6-8 parts
45-50 parts, water
Now when using a certain amount of soil curing agent is sprinkled upon with 30 times of water on the roadbed that excavated, penetrates into after in soil one hour until solution, just can carry out rolling to required compacting.
Compared with prior art, the soil curing agent that the present invention has changes the character of soil, and soil particle is after charge effect and ion-exchange, spoiled soil adsorbed film of water, moisture content in soil is easily discharged, and after using this soil-solidified-agent, the wetting ability of soil reduces; After rolling, permeability coefficient decline, between the soil particle of formation, consolidation is got up, thus reduce water to the destruction of roadbed and effectively prevent burst and become muddy when a thaw sets in phenomenon, raising way supporting capacity.Ability the present invention being had can improve the anti-rainwater of road link to soak and rinse, is specially adapted to the more south of rainwater and uses, improve supporting capacity and the work-ing life of road, reduce the maintenance cost of road simultaneously.
Embodiment
Below in conjunction with embodiment, the invention will be further described, and described embodiment is only the present invention's part embodiment, is not whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments used obtained under creative work prerequisite, belongs to protection scope of the present invention.
Embodiment one
First add 45 parts, the water calculated by weight in a reservoir, after the dilute sulphuric acid then adding 0.8 part stirs, add Witco 1298 Soft Acid 50 parts again, add polyacrylamide 10 parts, 30 parts, magnesium oxide, 17 parts, calcium phosphate, water glass 3 parts, sodium lignosulfonate 0.2 part, polyvinylpyrrolidone 6 parts after stirring again, stir after adding obtained soil curing agent.Wherein, though the order that adds of polyacrylamide, magnesium oxide, calcium phosphate, water glass, sodium lignosulfonate, polyvinylpyrrolidone successively.
Embodiment two
First add 50 parts, the water calculated by weight in a reservoir, after the dilute sulphuric acid then adding 2 parts stirs, add Witco 1298 Soft Acid 55 parts again, add polyacrylamide 15 parts, 20 parts, magnesium oxide, 20 parts, calcium phosphate, water glass 2 parts, sodium lignosulfonate 0.5 part, polyvinylpyrrolidone 8 parts after stirring again, stir after adding obtained soil curing agent.Wherein, though the order that adds of polyacrylamide, magnesium oxide, calcium phosphate, water glass, sodium lignosulfonate, polyvinylpyrrolidone successively.
Embodiment three
48 parts, water, dilute sulphuric acid 1.7 parts, Witco 1298 Soft Acid 53 parts, polyacrylamide 12 parts, 25 parts, magnesium oxide, 18 parts, calcium phosphate, water glass 2.5 parts, sodium lignosulfonate 0.3 part, polyvinylpyrrolidone 7 parts.Preparation method and embodiment one, implement two preparation method identical.
Embodiment four
47 parts, water, dilute sulphuric acid 1.5 parts, Witco 1298 Soft Acid 54 parts, polyacrylamide 14.5 parts, 13 parts, magnesium oxide, 17 parts, calcium phosphate, water glass 2.4 parts, sodium lignosulfonate 0.4 part, polyvinylpyrrolidone 6.5 parts.Preparation method and embodiment one, implement two preparation method identical.
The soil curing agent that the present invention has changes the character of soil, and soil particle is after charge effect and ion-exchange, and spoiled soil adsorbed film of water, makes the moisture content in soil easily be discharged, and after using this soil-solidified-agent, the wetting ability of soil reduces; After rolling, permeability coefficient decline, between the soil particle of formation, consolidation is got up, thus reduce water to the destruction of roadbed and effectively prevent burst and become muddy when a thaw sets in phenomenon, raising way supporting capacity.Ability the present invention being had can improve the anti-rainwater of road link to soak and rinse, is specially adapted to the more south of rainwater and uses, improve supporting capacity and the work-ing life of road, reduce the maintenance cost of road simultaneously.
