Shallow soft-base soil curing technology and system

Abstract

The invention provides a shallow soft-base soil curing technology and system. The shallow soft-base soil curing technology can be used to conduct curing treatment on shallow soft-base soil, such as shallow soft-base sludge and shallow soft-base silt. According to the shallow soft-base soil curing process, in the curing construction process, the position of the shallow soft-base soil is not required to be moved, only a soft-base soil curing agent is required to be added into the shallow soft-base soil located in the original position, and stirring and mixing are conducted on the shallow soft-base soil located in the original position and the soft-base soil curing agent, so that the curing construction procedure is greatly simplified, the construction efficiency is improved, and the construction cost is reduced. The invention further provides a sludge curing agent and a silt curing agent. By using the provided sludge curing agent and the silt curing agent to conduct curing treatment on the shallow soft-base sludge and the shallow soft-base silt, the good curing effect can be obtained, and formed cured soil has high unconfined compressive strength and further has a gas isolation effect, so that no odor gas is emitted, and environmental safety is ensured accordingly.

Description

technical field [0001] The invention relates to the field of soft soil treatment, in particular to a shallow soft soil solidification process and a shallow soft soil solidification system. Background technique [0002] In order to expand the usable area of ​​the land base, related projects such as sea reclamation, silt solidification, and silt solidification will be carried out. In the construction process of the above-mentioned projects, a curing agent will be added to the soft soil with weak bearing capacity to change the aggregate structure of the soft soil, increase the affinity between molecules in the soil, and make the soft soil solidify into a strong bearing capacity. , Consolidated soil with low water content. [0003] Based on the composition and properties of the existing curing agent, when curing the shallow soft soil, it is necessary to dig out the shallow soft soil first, then mix the curing agent with the excavated shallow soft soil, and finally The shallow ...

AI Technical Summary

Problems solved by technology

[0003] Based on the composition and properties of the existing curing agent, when curing the shallow soft soil, it is necessary to dig out the shallow soft soil first, then mix the curing agent with the excavated shallow soft soil, and finally Move the shallow soft soil mixed with curing agent back to its original position. The multiple position movements of the shallow soft soil increase the construction steps, reduce the construction efficiency and increase the construction cost

[0004] In addition, because the soft foundation soil (such as sludge, silt) contains a large amount of pollutants, the formed solidified soil also contains a large amount of polluting substances, and the long-term retained pollutants are easy to rot and smell, making the solidified soil emit a foul smell. causing adverse effects on the environment
