Problems solved by technology

Most of the existing liquid soil curing agents are strongly acidic or alkaline, which will not only bring great danger to the operator during use, but also cause certain damage to the ecological environment around the place of use.
In addition, the existing liquid soil solidifiers have poor compressive capacity, water stability and freezing stability, and their production process not only consumes a lot of energy, but also causes environmental pollution to varying degrees.

[0025] (2) Preparation method of soil stabilizer

[0026] A kind of preparation method of soil solidifying agent, specifically can comprise following operation:

[0027] Step 1, in parts by weight, heat 7 parts of distilled water to at least 60°C, add 0.4 parts of calcium lignosulfonate, 0.9 parts of sodium polycarboxylate, and 1.7 parts of lithium hydroxide to the distilled water, stir and mix until each group (namely, the three components of calcium lignosulfonate, sodium polycarboxylate and lithium hydroxide) were completely dissolved, and then kept at a constant temperature of 60°C for at least 24 hours to prepare an alkaline neutralizing solution.

[0028] Specifically, after adding calcium lignosulfonate, sodium polycarboxylate, and lithium hydroxide into distilled water, usually stirring for 1 to 2 hours, the calcium lignosulfonate, sodium polycarboxylate, and lithium hydroxide three components are completely dissolved. This process is mainly to prepare alkaline neutr...

Embodiment 1

[0045] A kind of soil solidifying agent A is prepared by adopting the preparation method of the soil stabilizing agent described in the above-mentioned technical scheme; its special feature is: in the process four, the alkaline neutralization solution and the acidic fatty alcohol sulfide The mixing ratio is 1:1 by weight; thus the soil stabilizer A with a pH value of 6.5 is finally prepared.

Embodiment 2

[0047] A kind of soil solidifying agent B is prepared by adopting the preparation method of the soil stabilizing agent described in the above-mentioned technical scheme; its special feature is: in the process four, the alkaline neutralization solution and the acidic fatty alcohol sulfide The mixing ratio is 0.85:1 by weight; thus the soil stabilizer B with a pH value of 5.5 is finally prepared.

Abstract

The invention discloses a soil solidifying agent, and a preparation method and a use method thereof. The soil solidifying agent is prepared from, by weight, 0.4 parts of calcium lignin sulfonate, 0.9 parts of sodium polycarboxylate, 1.7 parts of lithium hydroxide, liquid aluminum dihydrogen phosphate, illegally recycled waste cooking oil, sulfamic acid and distilled water, the pH value of the soil solidifying agent is 5-9, a weight ratio of the illegally recycled waste cooking oil to the liquid aluminum dihydrogen phosphate is 1.5:1, and the use amount of sulfamic acid is 1 / 2 of the total weight of the illegally recycled waste cooking oil and the liquid aluminum dihydrogen phosphate. The preparation method of the soil solidifying agent comprises the following steps: preparing an alkaline neutralization solution, preparing acidic fatty alcohol sulfide, mixing the alkaline neutralization solution with the acidic fatty alcohol sulfide, layering and extracting, and filtering to prepare the finished soil solidifying agent. The soil solidifying agent provided by the invention is not strong acidic or alkaline, and has the advantages of high safety, no pollution to environment, strong compression resistance, high water stability, high freeze stability and realization of waste utilization of the illegally recycled waste cooking oil; and the preparation method of the soil solidifying agent has the advantages of low energy consumption, no pollutants, safety and environmental protection.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a soil curing agent, a preparation method and a use method thereof. Background technique [0002] Soil stabilizer is a new type of engineering material synthesized from a variety of inorganic and organic materials to stabilize various types of soil and improve the technical performance of soil engineering. In engineering construction, the use of soil curing agent can replace traditional road construction materials such as lime, cement, fly ash, gravel, gravel, etc., and has the advantages of less consumption, local materials, fast curing speed, high early strength, and saving construction time Therefore, it has been widely used in many fields such as highway subgrade, railway subgrade, embankment solidification, building foundation, airport leveling and solidification, and slope fixation. [0003] In the prior art, soil curing agents are mainly divided into two types: solid soi...
