Environment-friendly type collapsible loess foundation structure and treatment method thereof

Abstract

The invention discloses an environment-friendly type collapsible loess foundation structure and a treatment method thereof. The environment-friendly type collapsible loess foundation structure comprises undisturbed soil, a foundation pit and compaction piles. The undisturbed soil is arranged around the foundation pit, and the compaction piles are arranged in the undisturbed soil. The compaction piles are arranged in an equilateral triangle plum blossom shape in the undisturbed soil layer. A cushion layer is arranged at the lower portion of an independent foundation, and solid piles are arranged at the lower portion of the cushion layer. The compaction piles are arranged around the independent foundation and include the solid piles and virtual piles, wherein the solid piles are located at the lower portions of the virtual piles. The foundation treatment method comprises pile arranging, pile driving and excavating. The environment-friendly type collapsible loess foundation structure andthe treatment method thereof have the beneficial effects that the excavation amount is small, the environment friendliness effect is good, the construction period is short, and the manufacturing costis low.

Description

technical field [0001] The invention belongs to the technical field of foundation treatment, and in particular relates to an environment-friendly collapsible loess foundation structure and a treatment method thereof. Background technique [0002] In my country's collapsible loess area, the independent foundation foundation treatment is carried out, such as figure 1 As shown, the usual method is to excavate as a whole to the elevation of the independent foundation, and then pile piles all over the site within the excavation range; there is also a deep layer replacement, which requires slope setting, foundation enlargement, side slope support, etc., resulting in a large amount of earthwork excavation , long construction period and high construction cost. In terms of environmental protection, the cost of dust control is high and the cycle is long; construction equipment and machinery are running a lot, and noise pollution lasts for a long time; water resources are wasted serio...

Problems solved by technology

[0002] In my country's collapsible loess area, the independent foundation foundation treatment is carried out, such as figure 1 As shown, the usual method is to excavate as a whole to the elevation of the independent foundation, and then pile piles all over the site within the excavation range; there is also a deep layer replacement, which requires slope setting, foundation enlargement, side slope support, etc., resulting in a large amount of earthwork excavation , long construction period and high construction cost

In terms of environmental protection, the cost of dust control is high and the cycle is long; construction equipment and machinery are running a lot, and noise pollution lasts for a long time; water resources are wasted seriously, and there is a lot of solid waste; it is especially difficult to prevent dust and haze at construction sites in winter
