AI Technical Summary

Technical Problem

Existing equipment is easily damaged by vibration during blasting operations, especially large equipment, which has insufficient seismic resistance and cannot effectively prevent the propagation of vibration.

Method used

A vibration damping trench is excavated between the existing equipment and the blasting point, and a structural unit consisting of vertical support columns and flexible material support pipes is installed. The support pipes are filled with damping medium, and the vibration energy is absorbed through a multi-stage energy dissipation method, including initial energy dissipation by the damping medium, secondary energy dissipation by the elastic support, tertiary energy dissipation by gas injection, and auxiliary energy dissipation by the buffer spring.

Benefits of technology

It effectively dissipates blasting vibration energy, prevents vibration from being transmitted to existing equipment, improves seismic resistance, and is suitable for repeated use, especially for the protection of large equipment.
