AI Technical Summary

⚠Technical Problem

Existing recyclable anchor cables are complex and difficult to recycle, and are prone to deformation, jamming and other problems, which can lead to non-recyclability or increased engineering costs.

⚗Method used

Design a recyclable prestressed anchor cable including steel strands, supports, connecting components, and a recyclable cable. Through the tapering design of the anchoring section and the connecting part, and the cooperation of the clamping components, the anchor cable can be stably installed and reclaimed. The prestress is transferred by grouting and tensioning processes, and the steel strands are relaxed to separate the components during recycling.

🎯Benefits of technology

This design achieves a simple anchor cable structure, a clear force transmission path, easy installation and recycling, reduced pollution, increased the use value and turnover rate of anchor cables, and reduced project costs.
