Abstract

The present invention provides an earthiness solidifying agent which is prepared from 5 wt% to 15 wt% of sulfonic group compound, 5 wt% to 15 wt% of wetting agent, 10 wt% to 20 wt% of KN-1 number earthiness reinforcing agent, 15 wt% to 30 wt% of one or any combustion of sulphuric acid, hydrochloric acid and formic acid, 10 wt% to 40 wt% of sodium sulfate or sodium chloride and 10 wt% to 30 wt% of iron chloride and / or aluminum sulfate. A base layer of a highway surface uses composite solidifying soil prepared from soil containing less cement, lime or cement and lime, and the earthiness solidifying agent to replace traditional materials for base layers of highway surfaces. Every technical index of the base layers of highway surfaces reaches national specified standards. The earthiness solidifying agent overcomes defects caused by the use of the traditional materials for base layers of highway surfaces simultaneously, is beneficial to the protection of ecological environment, saves energy resources, reduces transportation cost and greatly reduces the engineering cost of base layers of highway surfaces. The composite solidifying soil can be used in the construction of surfaces of highways or dams.

Description

A kind of soil solidifying agent

Technical field

The present invention relates to a kind of solidifying agent that can solidify soil property, relate in particular to the solidifying agent of a kind of road construction, particularly a kind of solidifying agent that is used for the curing soil property of highway road surface with the curing soil property.

Background technology

In road construction, the highway road surface traditional material comprises lime, cement, rubble, gravel etc.Obtaining these materials need cut into a mountain for quarrying, and therefore can produce the mountain area ecotope and destroy; Cement, lime are fired needs a large amount of energy; Use these materials also to need a large amount of trucking costs, increased the construction costs of road construction; These materials have pollution to surrounding environment in production, transportation in using.Both at home and abroad in road construction, all, there was external solidifying agent to enter China in recent years at present, and was in the experimental stage of application at present, and costs an arm and a leg in the equivalent material of the new sub-surface of development.

Summary of the invention

The object of the present invention is to provide a kind of soil solidifying agent that can solidify soil property.This soil property solidifying agent added make compound consolidated soil in the soil property contain small amount of cement, lime or cement and lime and substitute the highway road surface traditional material, be used for highway road surface, overcome the shortcoming of using the highway road surface traditional material to bring, reduced the construction costs of cutting into a mountain for quarrying to destruction, save energy, the construction facility of mountain area ecotope, reduce pollution, reducing trucking costs, highway and reduce greatly environment.

Soil solidifying agent of the present invention component by weight percentage consists of:

1, sulfonic group compound 5-15%

2, wetting agent: trolamine and/or diethanolamine 5-15%

3, KN-1 soil property toughener 10-20%

4, one of 98% sulfuric acid, 36% hydrochloric acid, 85% formic acid or arbitrary combination 15-30%

5, Na ₂SO ₄And/or NaCl 21-35%

6, FeCl ₃And/or Al ₂(SO ₄) ₃10-30%

Above-mentioned sulfonic group compound can increase the drainage of soil property and the compacted density of soil property, can adopt one of the formaldehyde condensation products or the arbitrary combination of sulphonated oil, sulphonated phenol, sulfonated naphthalene, sulfonated acetone.Above-mentioned wetting agent can increase the perviousness of Chemical Composition to soil property, can adopt trolamine and/or diethanolamine.Above-mentioned KN-1 soil property toughener is to contain the sodium polyphosphate initial reduced body that is no less than two methyl, and it can improve the soil property consolidation strength.Above-mentioned sulfuric acid concentration is 98%, concentration of hydrochloric acid is 36%, formic acid concn is 85%.

Highway road surface adopts the compound consolidated soil of being made by soil solidifying agent of the present invention and the soil property that contains small amount of cement, lime or cement and lime, and every technical indicator (frost resistance, water tolerance, unconfined compression strength, the curved intensity of tension etc.) all reaches state specified standards.The above-mentioned compound consolidated soil that substitutes the highway pavement traditional material is based on soil property, only contain a small amount of lime, cement, can gather materials on the spot, overcome the shortcoming of using the highway road surface traditional material to bring, reducing cuts into a mountain for quarrying reduces greatly to destruction, save energy, the construction facility of mountain area ecotope, the pollution that reduces Construction on Environment, the construction costs that reduces trucking costs, highway.Reduce 15-50% in the local highway sub-surface cost that lacks conventional road-making material.

The preparation method of soil solidifying agent of the present invention is as follows:

1, acidifying: KN-1 soil property toughener is added in the reactor, open reactor, under the high degree of agitation condition, add acid---one of sulfuric acid, hydrochloric acid, formic acid or its arbitrary combination at a slow speed, in the process that adds acid, reduce the temperature of reactor simultaneously with water coolant, make the temperature of reactor not be higher than 60 ℃.Add acid back off-response still, left standstill 1.5-2 hour.Stand-by.

2, dissolving: in another reactor, put into FeCl ₃And/or Al ₂(SO ₄) ₃, and add that to make its dissolving back solution weight percentage concentration be 40% water, open reactor to its whole dissolvings.Resulting this solution is put into the reactor that above-mentioned acidifying is used, open reactor to stirring.

3, open the reactor that acidifying is used, gradually add wetting agent, sulfonic group compound, Na more successively then ₂SO ₄And/or NaCl is to stirring.
