Problems solved by technology

[0004] The present invention provides a soil stabilizer in order to solve the problems in the prior art, which can be added to the soil after being mixed with water, which will change the properties of the soil. Make the water in the soil easy to be discharged. After using this soil curing agent, the hydrophilicity of the soil will decrease. After rolling, the permeability coefficient will decrease, and the formed soil particles will be consolidated, thereby reducing the impact of water on the roadbed. Destroy and effectively prevent muddying, improve the bearing capacity of the road

Embodiment 1

[0020] First add 45 parts of water in parts by weight into the container, then add 0.8 parts of dilute sulfuric acid and stir evenly, then add 50 parts of dodecylbenzenesulfonic acid, stir evenly, then add 10 parts of polyacrylamide, magnesium oxide 30 parts, 17 parts of calcium phosphate, 3 parts of water glass, 0.2 parts of sodium lignosulfonate, and 6 parts of polyvinylpyrrolidone were added and stirred evenly to prepare a soil stabilizer. Among them, the order of adding polyacrylamide, magnesium oxide, calcium phosphate, water glass, sodium lignosulfonate, and polyvinylpyrrolidone does not matter.

Embodiment 2

[0022] First add 50 parts of water in parts by weight into the container, then add 2 parts of dilute sulfuric acid and stir evenly, then add 55 parts of dodecylbenzenesulfonic acid, stir evenly, then add 15 parts of polyacrylamide, magnesium oxide 20 parts, 20 parts of calcium phosphate, 2 parts of water glass, 0.5 parts of sodium lignosulfonate, and 8 parts of polyvinylpyrrolidone were added and stirred evenly to prepare a soil stabilizer. Among them, the order of adding polyacrylamide, magnesium oxide, calcium phosphate, water glass, sodium lignosulfonate, and polyvinylpyrrolidone does not matter.

Embodiment 3

[0024] 48 parts of water, 1.7 parts of dilute sulfuric acid, 53 parts of dodecylbenzenesulfonic acid, 12 parts of polyacrylamide, 25 parts of magnesium oxide, 18 parts of calcium phosphate, 2.5 parts of water glass, 0.3 parts of sodium lignosulfonate, polyethylene 7 parts of pyrrolidone. The preparation method is the same as that of Example 1 and Implementation 2.

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 [0001] The invention relates to a soil stabilizing agent used for paving roadbed or road surface by a soil stabilizing method. Background technique [0002] In the prior art, in engineering aspects such as road construction, water conservancy, and slope stabilization, it is necessary to solidify and harden the surface of the soft silt river soil. The most traditional method in the known roadbed treatment technology is to add a certain proportion of quicklime to the soil and mix it with the soil before rolling. This method not only causes serious pollution to the environment during the construction process, but also is difficult to obtain high-quality solidification treatment. , although other substances have appeared instead of quicklime as adhesives and soil stabilizers for roadbed treatment, such as the patent ZL02114518.0 soil stabilizer, which uses alkyl as C 10 —C 14 Alkylbenzenesulfonic acid, dilute sulfuric acid and neutral water glass are prepared i...
