Moving type soundproofing car of smooth blasting tunnels

摘要

The present invention relates to a mobile soundproofing vehicle for noise prevention in a tunnel blasting method that blocks explosion noise, explosion vibration noise, and blasted stones or dust from being released to the outside when the tunnel excavation construction is carried out by a blasting method. A main frame assembled horizontally; A vertical frame installed vertically on a middle portion of the lower frame and fixed by front and rear brace frames; A plurality of sound insulation boards which are assembled to the inside of the vertical frame in up, down, left and right to form a soundproof wall; Upper and lower sound insulation boards which are hinged to the upper and lower sides of the vertical frame and are installed to be foldable, and having a standard that is extended close to the ceiling and the floor of the tunnel when standing up and down; A side sound insulation board which is hinged to the left and right sides of the vertical frame and is installed to be foldable, and has a standard that is close to the left and right sides of the tunnel during the operation of expanding to the left and right sides; It is hinged to the upper and lower sides of the side soundproofing plate, and is installed to be foldable, and consists of upper and lower auxiliary soundproofing plates having a standard spreading close to the side and bottom of the tunnel when standing up and down. It is a device with the characteristics of explosion noise, vibration sound, and stone and stone powder not to be released to the outside during tunnel excavation work.
