Description

Technical Field

[0001] The utility model relates to the technical field of dust suppression devices for foundation pit construction, and more specifically, to a dust suppression device for foundation pit construction used in construction engineering. Background Art

[0002] Nowadays, in the construction industry, because the buildings under construction are relatively tall, the foundation of the building needs to be more firmly constructed at the beginning of construction, which requires a deeper and larger foundation pit to wrap the foundation; but the foundation pit will generate a lot of dust when in use. The raised dust will not only block the workers' vision and reduce construction efficiency, but also cause damage to the workers' respiratory system. This requires the use of certain equipment to suppress the dust inside the foundation pit.

[0003] Many dust suppression devices currently in use generally use water mist to suppress dust. However, current devices are basically connected to the sprinkler heads through copper tubes for threaded connection, and the connected sprinkler heads are basically direct-spray atomizing sprinkler heads. As a result, current devices can generally only spray at certain locations or in one direction. This results in insufficient spraying, resulting in a lot of dust still flying upwards, which will still cause damage to the workers' respiratory system. Utility Model Content
