Embodiment Construction

[0024] figure 1 It is the schematic flow sheet of the embodiment of the construction method of solidified soil pile of the present invention, figure 2 It is a structural schematic diagram of the restrained and solidified soil pile of the present invention. Such as figure 1 with figure 2 Shown, the construction method of solidified soil pile of the present invention can comprise:

[0025] S1. A pile hole 1 is set in the foundation to be constructed and a restraint device 2 is set in the pile hole 1;

[0026] S2. Filling the solidified soil mixture formed by mixing the soil material and a curing agent comprising at least a cementitious component and an expansive component in the restraint device 2; and

[0027] S3. The solidified soil mixture 3 in the restraint device 2 is compacted to form a solidified soil pile.

[0028] Specifically, the pile hole 1 can be set on the polluted ground in a known manner, for example, a long auger drilling machine is used to construct the ...

Abstract

The invention provides a construction method for stabilized soil piles. The construction method comprises the following steps of arranging pile holes in a foundation to be constructed, and arranging restraining devices in the pile holes; filling the restraining devices with stabilized soil mixtures formed by blending a stabilizing agent with soil materials; and sealing the stabilized soil mixtures in the restraining devices to form the stabilized soil piles. By adopting the construction method, the problems that the strength of pile body stabilized soil of the stabilized soil piles is not high and the bearing capacity of pile soil is low are solved, and the increase of the strength of the stabilized soil and the improvement on the bearing capacity of the stabilized soil piles are realized; and the simplicity in operation is realized and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of foundation treatment, in particular to a construction method for solidified soil piles. Background technique [0002] It is one of the important methods to strengthen the foundation by mixing the solidifying agent with the foundation soil evenly to make it solidify into a solidified soil with a certain strength. There are a variety of technologies that can use curing agents to solidify the soil and make solidified piles, such as deep mixing method, powder spraying pile method, high-pressure rotary spraying method, etc. [0003] According to the existing research results, if the curing agent contains not only the cementing component but also the expansive component, the expansive hydrate produced by the curing agent can fill the pores in the consolidated soil, thereby greatly improving the strength of the consolidated soil. However, expansion can also destroy the structure of the stabilized soil. Therefor...
