Description

A kind of soil solidifying agent

Technical field

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

Background technology

In highway 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 ecological environment and destroy; Cement, lime are fired needs a large amount of energy; Use these materials also to need a large amount of freights, increased the construction costs of highway construction; These materials have pollution to surrounding environment in production, transportation in using.Both at home and abroad in highway construction, all, there was external curing compound 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 substitution 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 curing compound 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, energy conservation, the construction facility of mountain area ecological environment, reduce pollution, reducing freight, highway and reduce greatly environment.

Soil solidifying agent of the present invention component is by weight percentage formed and is comprised:

1, sulfonic group compound 5-15%

2, wetting agent 5-15%

3, KN-1 soil property reinforcing agent 10-20%

4, one of sulfuric acid, hydrochloric acid, formic acid or make up 15-30% arbitrarily

5, Na ₂SO ₄And/or NaCl 10-40%

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 of sulfonated oil, sulphonated phenol, sulfonated naphthalene, sulfonated acetone or combination arbitrarily.Above-mentioned wetting agent can increase the permeability of chemical analysis to soil property, can adopt triethanolamine and/or diethanol amine.Above-mentioned KN-1 soil property reinforcing agent 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 (freexing tolerance, water resistance, 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, energy conservation, the construction facility of mountain area ecological environment, the pollution that reduces Construction on Environment, the construction costs that reduces freight, highway.Reduce 15-50% in the local highway sub-surface cost that lacks conventional road materials.

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

1, acidifying: KN-1 soil property reinforcing agent 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 any combination at a slow speed, in the process that adds acid, reduce the temperature of reactor simultaneously with cooling water, 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 percent 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.

KN-1 soil property reinforcing agent can arrive peaceful new technology development Co., Ltd of Songyuan City, Jilin Province section and buy (address: Ningjiang District industrial park, postcode: 138000) during soil solidifying agent of the present invention was raw materials used.Other material market all has sale.
