Device for removing arch crown dangerous rocks by utilizing blasting shock waves based on Miura-Ori

Abstract

The invention discloses a device for removing arch crown dangerous rocks through blasting shock waves based on Miura-Ori. The device comprises a bottom plate, a Miura-Ori assembly arranged on the bottom plate and a shock wave absorption mechanism arranged on the bottom plate. The Miura-Ori assembly comprises a folding plate arranged on the bottom plate and a rock crushing plate arranged at the end part of the folding plate and used for crushing the arch crown dangerous rocks. According to the device, through the crushing plate on the folding plate, shock waves are used for conducting vibration crushing on the arch crown dangerous rocks through multiple times of reflection, the purpose of removing the dangerous rocks is achieved, and the problem that the construction period is long due to the fact that existing tunnel excavation needs the procedures of ventilation and dust falling, mechanical dangerous rock removing, manual dangerous rock removing and the like is solved.

Description

Technical field [0001] The present invention relates to the field of engineering and technology, and more particularly to a device based on three-pu folding utilization blasting shock waves to exclude the darnger of stone. Background [0002] Sanpo fold is a folding technique invented by Sanmun Lightlings of Textprint of Honorary from Tokyo University of Japan. This technique is to unfold the item on both ends of the diagonal, and in turn in turn in contraction. This method can save space, and can avoid loss of folding and deployment. Studies have found that this method can reduce the volume of the article by 25 times, and enhance the energy density 14 times. [0003] The tunnel often needs to be excluded during the construction process, but the current tunnel excavation needs to be ventilated, mechanical excavation of dangerous stone and artificially excluding dangerous stone and other processes, long construction period, often blasting during tunnel excavation, At this time, du...

AI Technical Summary

Problems solved by technology

[0005] In view of this, the device for removing dangerous rocks on the vault in this technical proposal uses the broken plate on the folded plate to vibrate and break the dangerous rocks at the vault by multiple reflections of shock waves, so as to achieve the purpose of removing dangerous rocks and solve the current problem. Tunnel excavation needs to go through ventilation and dust reduction, mechanical removal of dangerous rocks and manual removal of dangerous rocks and other processes, resulting in a long construction period
