Abstract
The present invention relates to a soil stabilizer for laying a road bed or a pavement by a soil stabilization method. The present invention is uniform liquid prepared from the following components by weight ratio: 100 of alkyl benzene sulfonic acid, 300 to 500 of water, 0.5 to 3 of diluted sulfuric acid and 1 to 12 of neutral water glass. The soil stabilizer can be diluted by arbitrary multiple water at a construction field. The present invention has the advantages of no combustion, no poison, no danger and no environmental pollution. The soil stabilizer is added into soil to change the nature of the soil so that the water content of the soil is reduced, and the water content is further discharged by rolling. The soil is compacted into high compactness, and simultaneously, the soil has hydrophobic performance. Accordingly, road bed destroy by the water is reduced, and a frost boil phenomenon of the soil can be effectively prevented. Soil particles generate a lithification phenomenon by the long-term chemical reaction of the road bed along with the increase of service time, and the compactness of the road bed is more and more large. The road bed is more and more rigid, and bearing capacity is more and more high.
Description
(1) technical field
The present invention relates to a kind of soil stabilizer that uses with subjecting soil to stabilisation making roadbed or paving, refer in particular to the soil ground and use sulfonated aromatic substance organic materials as the main soil stabilizer of forming.
(2) background technology
The most traditional method is to roll add a certain proportion of unslaked lime and mixing with soil in soil after in known roadbed treatment technology, and this method not only causes severe contamination but also is difficult to obtain high-quality roadbed environment in construction process.Though occurred modern age replacing tackiness agent and the soil stabilizer of unslaked lime as the roadbed processing with other material, Chinese patent 93115134.1 (" cementing agent for road material and preparation method thereof ") but this method exists the materials complexity for example, loaded down with trivial details and other shortcoming of construction process.
(3) summary of the invention
The objective of the invention is research and seek out a kind of material, it should have preferable make soil stabilization and agglutinating effect, is mixed in the soil after rolling, and the moisture content in the soil is discharged from, and soil can be compacted to very high degree of compactness.Carry out a large amount of research through us, selecting alkyl benzene sulphonate (ABS) is a kind of highly desirable soil stabilizer and tackiness agent.Alkyl benzene sulphonate (ABS) can all disperse in water, do not fire, toxicological harmless, do not have dangerous, do not cause environmental pollution, with join the character that can change soil in the soil after water mixes, make soil become hydrophobic nature, make soil particle, reduce the plastic limit of clay through the charge effect chap from wetting ability, increase the degree of compactness of soil, capillary interstice is diminished, and permeability coefficient descends, and the moisture content in the soil is reduced, through rolling, moisture content further is discharged from, and draws into the increase of fixed and friction between the soil particle, makes soil be compacted to very high degree of compactness, simultaneously because soil has had hydrophobic nature, thereby reduce water to the destruction of roadbed with prevent argillous frost boiling phenomenon effectively.Growth along with duration of service, roadbed is through over a long time chemical reaction, soil particle generation lithification phenomenon makes the degree of compactness of roadbed increasing, roadbed is also more and more harder, bearing capacity is more and more higher, has prolonged the work-ing life of road greatly, through traffic loading rolling road, the degree of compactness of roadbed can be bigger, and supporting capacity is also more and more higher.
In order to improve carrying out smoothly of result of use in construction process and operation, alkyl benzene sulphonate (ABS) must and water glass, dilute sulphuric acid water be mixed with uniform liquid so that at the construction field (site) can be with the water of any multiple towards rare use.Alkyl benzene sulphonate (ABS) preparation liquid need add industrial dilute sulfuric acid to be controlled its pH value and maintains about 2～3, adds the neutral water glass of modulus 3.1～3.4 again, to guarantee this soil stabilizer the use properties of the best is arranged.
The composition optimum weight ratio of this soil stabilizer is:
Alkyl benzene sulphonate (ABS) 100
Water 300～500
Dilute sulphuric acid 0.5～3
Neutral water glass 1～12
Alkyl benzene sulphonate (ABS) is a kind of intermediate of petrochemical industry in modern age, and the alkyl in the alkyl benzene sulphonate (ABS) that this soil stabilizer adopts is C

(4) embodiment
Embodiment one
In the container that band stirs, add 500 kilograms in clear water, start to stir and slowly add 100 kilograms of alkyl benzene sulphonate (ABS)s, add 12 kilograms of control of dilute sulphuric acid and neutral water glass pH simultaneously and maintain about 2～3, stirring is the soil stabilizer finished product, and the actual amount of dilute sulphuric acid is 2.5～3 kilograms.
Embodiment two
In the container that band stirs, add 300 kilograms in clear water, start stirring and slowly add 100 kilograms of alkyl benzene sulphonate (ABS)s, add 1 kilogram of dilute sulphuric acid and neutral water glass simultaneously, control pH maintains about 2～3, stirring is the soil stabilizer finished product, and the actual amount of dilute sulphuric acid is about 0.5 kilogram.
