AI Technical Summary

Technical Problem

Existing technologies are insufficient in protecting against gully-type debris flows and high-altitude landslides and rockfalls. Traditional retaining structures are prone to damage, especially under high-energy impacts. Furthermore, they are difficult and costly to construct and cannot effectively protect the safety of road and railway engineering projects.

Method used

A barrier structure using intersecting flexible steel strands is combined with climbing beams and reverse prestressed anchor cables to connect with the mountain. Through the toughness of the flexible steel strands and the cross-clamp connection, a high-energy barrier structure is formed. Combined with a concrete low dam to fix the bottom, it achieves protection against debris flows and rockfalls.

Benefits of technology

It improves the protective capacity of the barrier structure, enhances its toughness and stability, is easy to maintain, reduces maintenance costs, and can effectively resist the impact of high-energy debris flows and rockfalls, protecting the safety of road projects.
