Abstract
The invention provides a blast resistant chamber, which comprises blast resistant walls in four directions, namely the left side, right side, rear side and upside. The blast resistant walls are composed by inner side steel plates, outer side steel plates and soil arranged between the inner side steel plates and the outer side steel plates. The blast resistant walls of the blast resistant chamber is in steel-soil mixed structures, and once blast occurs during fireworks and crackers production, the soil can buffer, thereby having a good damping effect on blast wave. The inner side steel plate of the upside blast resistant wall of the blast resistant chamber is in an arc shape, and the arc shape is the same as wave front of the blast wave, thereby having good damping effect on the blast wave. During blast, the blast wave is prevented from forming reflection in the blast resistant chamber and enhancing destructive effect. The blast resistant chamber has extremely strong blast resistant and blast venting capabilities, thereby having strong prevention effect on sympathetic detonation or secondary damage caused by blast during fireworks and crackers production.
