AI Technical Summary
Existing foundation reinforcement devices suffer from difficulties in installation or are prone to sinking, resulting in poor overall performance.
A foundation reinforcement device was designed, including an expansion tube, a movable column, and an expansion plate. The expansion tube has a side hole on its side, and the movable column has an expansion plate at its outer end. The expansion plate is moved outward by pushing the movable column through the expansion column, thereby achieving lateral pressure on the foundation soil and achieving the reinforcement effect after the concrete solidifies.
It achieves convenient and labor-saving insertion, and can effectively press the foundation soil laterally after insertion to prevent the expansion tube from sinking. It has complete functions and strong practicality.
