AI Technical Summary

Technical Problem

Existing caisson construction suffers from poor adaptability, insufficient connection reliability, lack of real-time monitoring and adaptive control capabilities, and easy instability of support structures. In particular, it is difficult to achieve rapid and accurate diameter adaptation and stable sinking in alternating soft and hard strata.

Method used

The system employs a servo motor-driven double-ended screw and gear transmission system to achieve automatic adjustment of the support base. It integrates a humidity sensor and a pneumatic monitoring base for real-time monitoring of the formation status. Combined with water injection and grouting functions, it forms a closed-loop control strategy to ensure the verticality and stability of the caisson.

Benefits of technology

It enables rapid adaptation to caissons of different diameters, improves installation efficiency and connection reliability, ensures the vertical sinking and positioning accuracy of caissons under complex geological conditions, and reduces the risk of tilting and slippage.
