Problems solved by technology

[0007] 3. The timing and mechanism of adding cement are not clear in the existing mixing technology. In the construction process, the cement is added first and then the soil curing agent dilution is added. This will cause hydraulic reaction between the cement and the moisture in the soil, making the cement Caking, the silicate component in the cement will not react with the soil curing agent, which not only affects the performance of the cement but also affects the performance of the soil curing agent, and also increases the number of mechanical mixing

Embodiment Construction

[0025] In the following examples, the present invention discloses the best implementation of the method for mixing soil stabilizer stabilized soil, but the present invention is not limited to the implementation of the following conditions, time, etc., those skilled in the art On the basis of fully understanding the essence of the present invention, changes to the amount of raw materials, mixing ratio, mixing time, etc. still belong to the protection scope of the present invention.

[0026] The method for soil stabilizer stabilized soil mixing of the present invention may further comprise the steps:

[0027] 1) Mix quicklime and plain soil at 60kg / m 3 Thoroughly stir and stuff for 48 hours, as lime soil, so as to control the lime soil below the optimal water content, so that the particle diameter of the lime soil is more than 3cm and does not exceed 10%;

[0028] 2) According to the water content of the soil, the lime soil and the soil solidifying agent stock solution in step ...

Abstract

The invention discloses a method for mixing soil stabilizer stabilized soil, which comprises completely stirring quicklime and pure soil, and curing to serve as lime soil; diluting the lime soil with the raw slurry of a soil stabilizer to obtain a solution, and completely stirring; adding cement into the diluted soil stabilizer solution, and completely stirring; and compacting the soil stabilizer stabilized soil. By using quicklime and adding cement before compacting the soil stabilizer stabilized soil, the inventive method for mixing the soil stabilizer stabilized soil gives full play to the performance of the soil stabilizer, improves the load strength and water resistance of a soil stabilizer stabilized soil layer, has simple technology, and saves mechanical cost.

Description

technical field [0001] The invention relates to a method for mixing soil with a soil stabilizer and belongs to the field of construction engineering. Background technique [0002] Soil stabilizer is a new type of building material, which is used as the main building material like cement and lime. The soil stabilizer can be directly mixed with the soil according to the proportion and then applied to the project. However, in domestic practical applications, due to cost constraints, the dosage of soil stabilizer used is much smaller than that of foreign countries, and the lack of dosage is usually made up by adding lime and Portland cement. [0003] The application method of soil curing agent is generally soil curing agent+plain soil+lime+cement mixture. This mixture becomes soil curing agent to stabilize soil. The existing soil stabilization mixing technology borrows traditional lime stabilized soil (lime + plain soil) mixing technology, because this mixing technology is des...
