Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0022] It should be understood that terms such as "having", "comprising" and "including" used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0023] In a technical solution, such as figure 1 As shown, the collapsible loess foundation treatment method includes: step 1, within the construction scope of the collapsible loess foundation, a steel cylinder 1 is drilled;

[0024] The upper end of the steel cylinder 1 is open and the lower end is closed. An inner cylinder 2 is coaxially fixed inside the steel cylinder 1, and an annular water storage space is formed between the inner cylinder 2 and the steel cylinder (see figure 1 The space between the middle steel cylinder and the inner cylinder), the outer wall of the steel cy...

Abstract

The invention discloses a collapsible loess foundation treatment method. The collapsible loess foundation treatment method comprises the steps that steel cylinders are driven within a construction range of a collapsible loess foundation; a water storage space is filled with water, a water injection port is connected with the output end of a high pressure water pump through a water pipe; water is injected into the water injection port, a motor is started, when collapsible deformation is stable, the water in the water storage space is pumped out, the water pipe and the high pressure water pump are removed, and the motor is stopped; a grouting pipe is installed at the water injection port, cement slurry is injected into the water injection port, the motor is started again, raw materials of the cement slurry include cement, clay and water glass, the specific gravity of the cement slurry is not higher than 1.3, and the motor and a rotating shaft are removed after grouting is completed; themultiple steel cylinders are arranged within the construction range, and above operation is repeatedly carried out on the steel cylinders. The steel cylinders are used to be combined with high-pressure water injection, so that a soil body is capable of being subjected to collapsible deformation to be stable, then grouting is carried out, the steel cylinders and the soil body can be tightly combined, and the stability of the foundation is enhanced.

Description

technical field [0001] The invention relates to a foundation construction method. More specifically, the invention relates to a method for treating collapsible loess foundations. Background technique [0002] Collapsible loess has less compressibility in dry state and generally has higher strength. However, once it is soaked by water, the strength of collapsible loess will decrease rapidly, causing collapsible deformation. Although the current treatment methods for collapsible loess, such as replacement filling method and compaction pile method, can achieve results, there is still room for improvement. Therefore, it is urgent to design an improved treatment method for collapsible loess foundation. Contents of the invention [0003] An object of the present invention is to provide a method for treating collapsible loess foundations, which uses a steel cylinder combined with high-pressure water injection to make the soil collapsible and deformed until it is stable, and th...
