Embodiment 1

[0021] See figure 1 with figure 2 , The figure shows a collapsible foundation grouting material curing reinforcement structure provided in the first embodiment of the present invention, including gravel pile 1, foundation layer 2 and drainage device 3, gravel pile 1 extends longitudinally into the to be reinforced In the loess layer 4, multiple gravel piles 1 are arranged in a grid pattern, and the foundation layer 2 is sequentially provided with a geocell gravel layer 21, a waterproof layer 22, and a concrete surface layer 23 from bottom to top. The cell crushed stone layer 21 is combined with water glass grouting through a pre-embedded grouting pipe to form a whole. The drainage device 3 penetrates the foundation layer 2 and the bottom of the drainage device 3 extends into the loess layer 4.

[0022] Specifically, see figure 1 with figure 2 , The drainage device 3 and the gravel pile are arranged in parallel.

[0023] Specifically, see figure 1 with figure 2 The drainage de...

Embodiment 2

[0031] See figure 1 with figure 2 , The figure shows a collapsible foundation grouting material curing reinforcement structure provided by the second embodiment of the present invention. On the basis of the above-mentioned embodiment, this embodiment further makes the following as an improved technical solution: water Glass grouting components include isocyanate, active toughening agent and trimerization catalyst; water glass grouting includes the following components by weight percentage: water glass 46.6%, isocyanate 41.4%, active toughening agent 10.4%, trimerization catalyst 1.6%.

[0032] The water glass grouting enters the loess layer when the gravel pile and the geocell gravel layer are grouted, and strengthens the loess layer through consolidation. The water glass grouting ingredients include isocyanate, active toughening agent and trimerization catalyst. Specifically, 90 parts of water glass, 80 parts of isocyanate (MDI), 20 parts of active toughening agent and 3 parts...

Abstract

The invention provides a collapsible type foundation grouting material solidification reinforcing structure. The structure comprises gravel piles, a foundation layer and a water drainage device; the gravel piles vertically stretch into a loess stratum to be reinforced; the gravel piles are arranged in a gridding mode; the foundation layer comprises an earthwork standard room gravel layer, a waterproof layer, and a concrete face layer which are arranged in sequence from bottom to top; the gravel piles and the earthwork standard room gravel layer are combined with injected water glass grout viapre-embedded grouting pipes and form an entirety; the water drainage device is arranged in the foundation layer in a penetrating mode; and the bottom of the water drainage device extends into the loess stratum. The provided collapsible type foundation grouting material solidification reinforcing structure can effectively improve the overall stability and load bearing capacity of a foundation, andeliminate the hidden hazards of settlement deformation.

Description

Technical field [0001] The invention relates to a collapsible foundation processing structure, in particular to a collapsible foundation grouting material curing reinforcement structure. Background technique [0002] The collapsibility characteristics of the collapsible loess foundation bring varying degrees of harm to the building structure and the foundation of the square, and it is prone to large-scale settlement, cracking and tilting, which seriously affects its safety and use. The collapsible loess foundation needs to be treated to reduce the water permeability and compressibility of the loess foundation, control the occurrence of its collapsibility, and partially or completely eliminate the collapsibility. [0003] Collapsible loess is generally injected with water glass grouting to improve the compactness and bearing capacity of the formation. However, the existing water glass grouting material has a slower consolidation speed, and the bearing capacity of the stratum that i...
