Description

Technical Field

[0001] The invention relates to a spraying device, in particular to a dust removal spraying device for tunnel construction. Background Art

[0002] During the tunnel construction process, a large amount of dust will be generated. This dust will not only endanger the health of construction workers, such as causing respiratory diseases, but also affect the visibility of construction, increase the safety risk of construction, and may also have adverse effects on the equipment and engineering quality in the tunnel. Therefore, effective dust removal measures are crucial for tunnel construction.

[0003] Traditional tunnel dust removal spraying devices often have some limitations. For example, many devices have fixed spray angles or limited adjustment ranges. In a complex construction environment such as a tunnel, different construction stages and work areas have diverse requirements for spray angles.
