AI Technical Summary
Technical Problem
Existing tunnel protection structures lack effective means of kinetic energy absorption and release under rock bursts, leading to structural damage and subsequently tunnel deformation and dangerous disasters.
Method used
The protective structure adopts a segmented spliced layer structure, combined with buffer components and energy-absorbing components. It utilizes elastic support structure and hydraulic support structure to absorb and release the kinetic energy of the rockburst, avoid overall slippage, and enhance the support strength of the roadway.
Benefits of technology
It effectively absorbs and releases the kinetic energy of rock bursts, prevents damage to protective structures, extends service life, and improves the stability of the surrounding rock in the tunnel.
