AI Technical Summary

Technical Problem

Existing municipal greening barriers are unstable when subjected to external forces such as vehicle collisions or strong winds, easily loosening or tipping over, resulting in poor stability, increased maintenance costs, and safety hazards.

Method used

The system employs a combination of threaded nails and winches. The threaded nails are connected to a conical threaded cylinder via a spiral connection, and the winches are screwed into the soil or cement counterweight to form a tight multi-directional engagement. Combined with diagonal braces and reflective pads, the system enhances stability. Meanwhile, warning lights and flashing lights powered by bidirectional solar panels improve visibility.

Benefits of technology

It enhances the impact and wind resistance of the guardrail, reduces the risk of loosening, extends its service life, and improves the visibility and traffic safety of the guardrail.
