The movable folding arm type rotary water-spraying dust-removing device is suitable for different section tunnels and can cover the whole tunnel section.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, and in particular relates to a movable folding-arm rotary water spray and dust removal device. Background technique [0002] During tunnel construction, especially during the slag discharge process after tunnel blasting, the dust concentration is extremely high, and even if the slag discharge vehicle drives out of the tunnel, the slag body behind the vehicle bucket can still be the source of dust emission, which seriously pollutes the surrounding air. Although there is a ventilation system during tunnel construction, the dust concentration in the air is still extremely high during the slag discharge process, seriously affecting the health of workers working in other processes behind the tunnel face. [0003] The traditional water curtain dust suppression has a large water consumption, high cost, and is difficult to move. However, the spraying method of various cannon fog machines is d...
