Abstract

The invention provides a self-moving multi-stage dust settling device for a tunnel. The self-moving multi-stage dust settling device comprises a track and a dust settling device. The track is mountedon a vault of the tunnel along the axial direction of the tunnel; the dust settling device is hoisted on the track and can move linearly in the tunnel along the track; the dust settling device is provided with a spraying device for spraying water mist to the tunnel to dedust the tunnel; the spraying device controls swing and shrinkage of the spraying device through an electric cylinder; and the dust settling device comprises a first dust settling device, a second dust settling device and a third dust settling device for spraying the tunnel all around. The self-moving multi-stage dust settlingdevice is hoisted on the top of the tunnel and the spraying device can stretch, so that occupation of the space of the tunnel is reduced greatly. Normal work of other equipment and transit of tunnel constructors are not affected while the tunnel is sprayed to dedust, so that the tunnel construction efficiency is improved.

Description

technical field [0001] The invention relates to the field of tunnel construction, in particular to a tunnel self-moving multi-stage dust suppression device. Background technique [0002] With the development of my country's economic construction, tunnel construction projects are increasing day by day. Due to the remarkable advantages of strong adaptability and simple construction, the drilling and blasting method is widely used in tunnel construction projects. A large amount of smoke and harmful gases are produced on the subsurface, which will seriously pollute the environment of the working surface if they are not discharged out of the tunnel. In the past, fresh air was often used to dilute and discharge the tunnel surface. Seriously affect the air quality in the formed tunnel, which is not conducive to the health of construction workers. [0003] Chinese patent 201821689657.3 discloses a trolley curtain-type tunnel dust removal system, including a first dust reduction devic...
