Embodiment 1

[0018] The soil solidifying agent of the present embodiment is made by mixing raw materials in the following percentages by weight: 50% of sepiolite powder and 50% of rectorite powder.

[0019] The preparation method of the soil curing agent of this embodiment is as follows: according to the proportion of this embodiment, separately weigh sepiolite powder and rectorite powder, and mix them evenly to obtain the soil curing agent of this embodiment.

[0020] The application method of the soil curing agent in this embodiment when used as a road filler to solidify the soil is: first, take precipitation treatment measures such as turning over the sun to reduce the moisture content of the used soil to below 25%; then add the soil curing agent to the soil and stir evenly, and then the For the paving construction of road fillers, the mass of the soil curing agent is 13% of the mass of the soil with the moisture content reduced to below 25%.

Embodiment 2

[0022] The soil solidifying agent of the present embodiment is made by mixing raw materials in the following percentages by weight: 55% of sepiolite powder and 45% of rectorite powder.

[0023] The preparation method of the soil solidifying agent of the present embodiment is identical with embodiment 1.

[0024] The application method of the soil solidifying agent of this embodiment when solidifying the soil as a road filler is the same as in Example 1, the difference being that the quality of the soil stabilizing agent is 15% of the soil quality whose moisture content drops below 25%.

Embodiment 3

[0026] The soil solidifying agent of the present embodiment is made by mixing raw materials in the following percentages by weight: 60% of sepiolite powder and 40% of rectorite powder.

[0027] The preparation method of the soil solidifying agent of the present embodiment is identical with embodiment 1.

[0028] The application method of the soil solidifying agent of the present embodiment when solidifying the soil as a road filler is the same as in Example 1, and the difference is that the quality of the soil stabilizing agent is 18% of the soil quality whose moisture content drops below 25%.

Abstract

The invention discloses a soil solidifying agent, which is prepared by mixing the following raw materials in weight percentage: 40%-80% of sepiolite powder and 20%-60% of rectorite powder. In addition, the invention also discloses the use method and application of the soil solidifying agent. The soil solidifying agent of the present invention fully utilizes the advantages that sepiolite and rectorite have good water absorption, and the synergistic solidification of the two can not only improve the strength, reduce the shrinkage, but also effectively improve the optimum content of the soil. water volume, overcome the shortcomings of soil compaction difficulty when used as road subbase and roadbed filler, open up the application of sepiolite and rectorite in the field of soil curing agent, and reduce the cost of road construction by curing soil for road filler, It is also beneficial to protect the environment and can be used for sludge solidification treatment.

Description

technical field [0001] The invention belongs to the field of soft soil curing materials for roads, and in particular relates to a soil curing agent and its use method and application. Background technique [0002] In engineering practice, many natural foundations cannot meet the construction requirements. During construction, many soft soil foundations will be encountered. This type of foundation has low bearing capacity, slow strength growth, easy deformation and unevenness after loading, and large and stable deformation rate. Long time, with the characteristics of small permeability, thixotropy and rheology. If it is not handled properly, it will seriously affect the performance of the road. The main performance is that the uneven subsidence of the roadbed will lead to the damage of the road surface structure. Therefore, the treatment of soft soil foundation has always been a problem that plagues engineering construction. [0003] At present, the method of large-scale sof...
