AI Technical Summary

Technical Problem

Traditional basement raft foundations with tower crane rectangular foundations present challenges in high-rise building construction, including difficulties in site layout, construction difficulties, long construction periods, and high costs, especially in limited construction sites.

Method used

The tower crane adopts a rectangular slab pile foundation that utilizes precast piles from the underground parking garage ramp. The ramp piles serve as the foundation platform for the tower crane, and are combined with precast square piles, brick formwork, and concrete pads to form a stable tower crane foundation structure, simplifying the construction process and reducing costs.

Benefits of technology

It simplifies the layout of tower cranes in limited spaces, improves construction efficiency, reduces costs, reduces environmental pollution, and supports subsequent tower crane relocation, avoiding subsequent pile driver construction.
