AI Technical Summary

Technical Problem

In traditional external demolition processes, the supporting structure lacks a moving mechanism, making it difficult to provide stable support, accurate positioning, and safe movement during demolition. Furthermore, the hydraulic system lacks real-time suppression measures for pressure fluctuations and mechanical vibrations, affecting demolition accuracy and safety.

Method used

A special tooling for disassembling TBM outer casing was designed. It adopts a welded steel frame structure, combined with a double wheel set, pin shaft, clamping plate and support plate. Through real-time monitoring by multiple sensors and closed-loop control, it can achieve stable support, precise positioning and safe movement of the outer casing.

Benefits of technology

It achieves stable support, precise positioning, and safe movement during the dismantling process of the outer shell, reduces errors caused by human intervention, improves dismantling efficiency and safety, and reduces the risk of equipment damage.
