Blasting shock wave protection device

Abstract

The invention discloses a blasting shock wave protection device which comprises a bottom board. A protection wall is arranged at the upper end of the bottom board and comprises a framework and a wallbody; the framework is composed of a plurality of cross beams and a plurality of vertical beams; a plurality of water curtain sprayers are evenly distributed on the surface of the protection wall andare connected with a water tank through a water pipe; and the water tank is located at the upper end of the bottom board and on the rear side of the protection wall. The protection wall is composed ofa protection net, a polyurethane foam plastic layer and a pvc soft board, the shock wave protection and rubble blocking functions are achieved, the structure is light, transportation is convenient, the device can be repeatedly used, the structure of the protection wall is more stable through the arrangement of the cross beams, the vertical beams and reinforcement ribs, a water curtain is formed through the water curtain sprayers to achieve the function of weakening shock waves, dust flying generated by blasting can be reduced, and the device can move conveniently through arrangement of universal wheels, and can be repeatedly used.

Description

technical field [0001] The invention relates to the technical field of blasting protection, in particular to a blasting shock wave protection device. Background technique [0002] Factors affecting the environment, such as blasting flying stones, dust, and shock waves, will inevitably be produced during blasting operations. Therefore, retaining walls are often used for protection during construction. [0003] The patent with the application number CN201720332664.7 discloses a goaf shock wave barrier, which includes a planar reinforced concrete retaining wall and a waste rock layer, a fine sand layer and a curved reinforced concrete retaining wall located outside it in turn. The sandbags in the fine sand layer are bound to form a whole by binding ropes, and the binding ropes are fixed to the side wall or roof and floor of the roadway by expansion screws. The curved reinforced concrete retaining wall is an arched wall protruding forward, and the steel bars in the curved reinf...

AI Technical Summary

Problems solved by technology

However, this invention uses concrete wall stones and fine sand, which is heavy, inconvenient to transport, and cannot be reused, resulting in waste of resources, and has no function of reducing dust. Some dust is likely to be generated during the construction process, which affects the operators.
