Method and device for dust removal in tunnel construction

Abstract

The invention discloses a method and a device for dust removal in tunnel construction. The device includes a base, two supporting seats are fixedly connected to the left side of the top of the base, and a spraying structure is rotatably connected between opposite sides of the two supporting seats. The method and the device relate to the technical field of tunnel engineering. For the method and thedevice for the dust removal in the tunnel construction, the spraying structure is disposed, so that water enters an atomization device, is transformed into a water mist form, then is transported to two conveying pipes, and finally enters inside a spraying cylinder, at the moment, rotating blades can be driven to rotate by rotation of a driving motor, wind power generated when the rotating bladesrotate can blow out water mist entering the interior of the spraying cylinder, the two conveying pipes are disposed to spray the water mist at the same time to form convection, the flow of the water mist is increased, and so, the water mist is concentrated in the same area and is conveniently blew out by the rotating blades, and the water mist is relatively light and can be sprayed to farther peripheral places under the action of strong wind, thereby increasing the effect of dust removal.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a method and device for reducing dust during tunnel construction. Background technique [0002] Tunnel is an engineering building buried in the ground, and it is a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mine tunnels, and uniform tunnels. The structure of the tunnel includes the main building The main building is composed of a cave body and a portal, and the subsidiary equipment includes car shelters, fire-fighting facilities, emergency communication and waterproof and drainage facilities. The long tunnel also has special ventilation and lighting equipment. [0003] During the tunnel construction process, a large amount of dust will be generated inside the tunnel. In order to prevent the staff from inhaling too much dust and ensure normal construction in the tunnel, it is necessary to us...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a method and device for dust reduction in tunnel construction, which solves the problem that the existing dust reduction equipment consumes too much water and the spraying range is small, resulting in an unsatisfactory dust reduction effect
