AI Technical Summary

Technical Problem

Existing tower crane foundation reinforcement structures have a short service life and are prone to weld fatigue cracking under periodic lateral dynamic loads.

Method used

The structure adopts a combination of support base, positioning block and tilting connecting rod. The bottom of the support block protrudes to disperse the foundation pressure. The positioning bolt and positioning block work together to control the verticality of the tower section, forming a triangular stable structure, avoiding the welding structure. The connection stability is improved by combining locking ring and buffer layer.

Benefits of technology

It effectively reduces the risk of settlement, extends service life, avoids weld fatigue cracking, improves connection stability, and prevents connection failure caused by construction vibration.
