Description

Technical Field

[0001] The utility model relates to the technical field of dust suppression equipment, in particular to a dust suppression device in a subway underground station tunnel. Background Art

[0002] The construction of underground rail transit stations in urban downtown areas or main roads is affected by many surrounding engineering environments and traffic diversion. When the contradiction between the open-cut construction of subway stations and the ground traffic diversion is difficult to resolve, the covered (half-covered) construction method is usually adopted.

[0003] Excavators, impact hammers, etc. are lowered into the dark excavation hole from the shaft. As the construction progresses, the excavator digs in the front and the workers provide support as the excavator moves forward. When digging in the hole, due to the small space in the hole, the dust has a health impact on the workers' breathing. The existing atomization devices are divided into mobile or fixed types. The mobile sprayer cannot adapt to the change of the excavation position, so that the raised dust is easily dispersed from the side of the water mist, causing the deterioration of the construction environment.
