AI Technical Summary
The foundation of a tower crane is prone to shifting and tilting during the pouring process, which can lead to non-compliance with verticality requirements, affecting the installation and structural stability of the tower crane, and may even cause the tower crane to collapse.
The system employs a sinking mechanism, columns, adjustment mechanism, and support mechanism. The position of the anchor is adjusted by the cooperation of adjustment plates, moving blocks, screws, and rotating wheels. Before concrete pouring, a first and second base plate are pre-embedded to fix the anchor, and reinforcement blocks and installation blocks are used to enhance stability.
It effectively prevents the foundation from shifting or tilting during the pouring process, ensures the verticality of the foundation, improves the convenience of tower crane installation and structural stability, and avoids the risk of tower crane collapse due to unstable foundation.
