Description

Technical Field

[0001] The utility model relates to the field of dust suppression devices, and more specifically to a ground dust suppression device for underpass tunnel construction. Background Art

[0002] During the construction of an underpass tunnel, shield machines and other equipment are generally used for excavation, etc., so a large amount of dust is generated during the construction, which means that construction workers can only enter the tunnel wearing specific dust-proof helmets. The existing dust suppression devices generally install the shield machine first, open the hole, and then use support plates and water pipes to spray water in the tunnel. A large amount of water spraying will increase the water content in the tunnel, which may cause small streams of water to form in the tunnel, and the spraying of water cannot effectively suppress dust. For this reason, we propose a ground dust suppression device for underpass tunnel construction. Utility Model Content
