Description

Technical Field

[0001] The utility model relates to the technical field of foundation reinforcement, in particular to a reinforcement structure for soft foundation. Background Technique

[0002] A soft foundation refers to a foundation mainly composed of silt, silty soil, fill soil, miscellaneous fill or other highly compressible soil layers. This foundation has an excessively large natural water content, low bearing capacity, and is prone to sliding or consolidation settlement under load; due to the structural characteristics of the soft foundation itself, it is necessary to reinforce the soft foundation. A common soft foundation reinforcement measure is replacement treatment, that is, using an excavator to dig out part of the soil body, filling the excavated pit with gravel and soil with stronger bearing capacity and compacting it. In this way, there is a lack of a support structure on the outside of the reinforcement structure, and it is easily affected during the replacement process. Therefore, we propose a reinforcement structure for soft foundation. Content of the Utility Model

The fixed column is inserted into the ground by using a fixed cone, and the T-shaped block at the end of the protective sleeve is clamped into the T-shaped groove to connect multiple fixed columns. At the same time, the reinforcement wire is passed through the wire groove to connect and fix multiple fixed columns, thereby increasing the overall firmness. Finally, a filler is added to reinforce the soft foundation, which can effectively solve the problems in the background technique.
