Construction for preventing from noise and muckpile fly of tunnel drilling

摘要

The present invention is the noise of the equipment inevitably generated in the tunnel opening or tunnel excavation proceeds (puncture equipment, buoyancy loading equipment, force transport equipment, pumice treatment equipment, shotcrete placement equipment, concrete mixer equipment) and blasting sound and blasting force Tunnel Excavation Noise Reduction and Blasting Force Scattering Prevention Structure When the present invention is used when opening a tunnel, a steel beam having a standard equal to or larger than the tunnel section is installed in a straight line at a tunnel entrance (longer than an excavation equipment), and a soundproofing device (plate + soundproof nonwoven fabric + shotcrete) is provided between the steel beam and the steel beam. Install the temporary tunnel. The door frame is installed with the steel beam of the standard that the equipment can pass at the entrance of the temporary tunnel, and the soundproofing equipment is installed in the space between the gangjibo and the door frame. More than one soundproof curtain is installed in the steel door frame with the elasticity and elastic rubber belt vertically installed according to the noise level.;Temporary tunnel, Gangjibo, Soundproof nonwoven fabric, Soundproof film
