Multifunctional module type soil pressure applying and forming device

Abstract

The invention discloses a multifunctional module type soil pressure applying and forming device. The forming device comprises a top frame, a pressure applying forming module and soil body strength detection devices, is characterized in that baffles are arranged on the periphery of the top frame, and the pressure applying forming module comprises a plurality of convex bodies; filter devices are further arranged on the part, in contact with the soil body, of the module, and reinforcement bodies sleeve the filter devices; the upper part of the module and a top plate form a vacuum water collectingchamber, and the module is provided with water guide channels; and the top frame and / or the pressure applying forming module are further provided with auxiliary pressure applying devices, the bottomsof the convex bodies are further provided with vertical pile bodies. According to the device, the soil body can be subjected to rapid drainage, consolidation and forming, the device is suitable for shallow layers, middle layers and deep layers treatment, and therefore the device is wide in applicability, high in construction efficiency, short in construction period and low in construction cost.

Description

technical field [0001] The invention relates to the field of foundation reinforcement treatment, in particular to the field of reinforcement treatment of soft soil foundation, in particular to a multifunctional modular soil pressure forming device. Background technique [0002] The soil structure is generally composed of solid matter, liquid water and air. Different mixing ratios of various substances produce unequal pressure bearing capacity. When the applied pressure is greater than the bearing pressure of the soil body, it will be compressed and cause lateral movement and compression. Settlement requires artificial changes to the mixing structure ratio of the original soil. Under the action of external pressure, the compactness between the solid particles in the soil is increased, and the drainage material set in the soil is used to discharge liquid water and The channel of the air changes the mixed structure of the soil so that the proportion of the solid content is cont...

AI Technical Summary

Problems solved by technology

The above-mentioned drainage consolidation method has a very long construction period, usually six months to one year to complete, so the construction cost is very high and the efficiency is very low

[0004] The above drainage consolidation method is only suitable for large area construction

Moreover, since the height of the piled load is limited, it cannot be applied to occasions with high load-bearing requirements for soil
