AI Technical Summary

Technical Problem

Existing slope blasting protection devices are ineffective at blocking smaller rocks, posing a threat to construction workers and pedestrians. At the same time, the dust and toxic gases generated by blasting affect construction efficiency and health.

Method used

A flyrock protection structure for slope blasting is adopted, including a base, a fixing plate and a placement plate, and an automatic water spraying mechanism and a protective net are installed. The flyrock impact drives the water spraying system to spray a water curtain to dissolve dust and toxic gases, and the stability is improved by shock-absorbing components and rigid rods.

Benefits of technology

It effectively blocks flying rocks, dissolves dust and toxic gases in the air, protects the health of construction workers, improves construction efficiency, and enhances the stability of the equipment.
