Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tunnel construction, in particular to a tunnel construction dust removal equipment. BACKGROUND

[0002] Tunnel is a building constructed underground or underwater or in the mountain, laying railway or building highway for motor vehicles to pass. According to its location, it can be divided into three categories: mountain tunnel, underwater tunnel and urban tunnel. The tunnel passing through the mountain or hill to shorten the distance and avoid large slope is called mountain tunnel; the tunnel passing through the river or strait from the river or underwater is called underwater tunnel; the tunnel passing through the city underground to meet the needs of railway passing through the city is called urban tunnel. During the construction process of the tunnel, a large amount of dust is generated, which pollutes the environment and easily harms the health of workers.

[0003] The general water spray type tunnel construction dust removal equipment adopts fixed point spray dust removal operation. This equipment cannot move and pipe independently. In actual operation, tunnel excavation is carried out in real time. The place where the most dust is generated is the tunnel end near the excavation. This position changes in real time. Therefore, the fixed point tunnel construction dust removal equipment cannot meet the needs of spray dust removal in the tunnel excavation process. The spray equipment with water tank can move and spray dust removal, but due to the limited space of the tunnel, the storage capacity of the water tank is also limited. Generally, this equipment cannot continuously spray in one day of construction time, and often needs to stop work and supplement water outside the tunnel. The dust removal equipment connected with the water pipe extending into the tunnel is also prone to scattering of the hose, which hinders the movement of equipment and personnel in the tunnel.
