Embodiment 1

[0036] A soil stabilizer, which consists of the following components by weight:

[0037] Lignin 15 Yuan Mingfen 1.5 Triethanolamine 2.5

[0038] Silica fume 5 Refined naphthalene 3 Sodium p-aminobenzenesulfonate 10

[0039] Portland cement clinker 20 Anhydrous gypsum 3 Steel plant blast furnace water slag 50

[0040] After mixing the raw materials of the above-mentioned components according to the weight ratio, they enter into the end-process ball mill of the cement plant and grind them until the specific surface area is 350-400.

Embodiment 2

[0042] A soil stabilizer, which consists of the following components by weight:

[0043] Lignin 15 Yuan Mingfen 1.5 Triethanolamine 2.5

[0044] Silica fume 5 Refined naphthalene 3 Sodium p-aminobenzenesulfonate 20

[0045] Portland cement clinker 20 Anhydrous gypsum 3 Steel plant blast furnace water slag 50

[0046] After mixing the raw materials of the above-mentioned components according to the weight ratio, they are put into a cement ball mill together, and the ratio of balls and segments is adjusted, and they are ground until the specific surface area reaches 400 or more.

Embodiment 3

[0048] The soil stabilizer prepared in Example 1 of the present invention was used for roadbed anti-seepage treatment. Add the soil stabilizer of Example 1 that accounts for 4-8% of the original soil weight in the original soil of the roadbed, and process it according to the conventional treatment method. The soil body obtained after the treatment has a compressive strength above 3.2MPa, and has excellent Water stability and freeze-thaw resistance.

Abstract

The invention provides a soil body stabilizing agent comprising the following components by weight: 15 parts of lignin, 1.5 parts of glauber salt, 2.5 parts of triethanolamine, 5 parts of silica powder, 3 parts of refined naphthalene, 10 to 20 parts of sodium sulfanilate, 20 parts of cement clinker, 3 parts of gypsum and 50 parts of blast furnace slag. The soil body stabilizing agent provided by the invention has the characteristics of low dosage, high soil body consolidation strength, good stability and the like. The invention further provides a preparation method for the soil body stabilizing agent and an application of the soil body stabilizing agent to anti-seepage treatment of a road bed, a shoal, a river, a lake or a reservoir base layer.

Description

technical field [0001] The invention relates to a chemical product used for soil treatment, in particular to a soil stabilizer, its preparation method and application. Background technique [0002] In order to improve the bearing capacity of silt soil, methods such as backfilling gravel dynamic compaction method (or rolling method), manhole preloading method, and foundation pit drainage method are generally used to deal with it. station, blowing and filling silt, so that the elevation of the depression can be raised rapidly, so that the idle land can be used in advance. In the 1950s, siliconization was developed to change the properties of silt and improve the bearing capacity of soil. [0003] With the gradual deepening of my country's reform and opening up, the rapid development of the country, and the rapid development of transportation and urban construction, the above methods have been far from meeting the needs of national construction and development. For example, a...
