Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction dust reduction, in particular to a highway tunnel construction dust reduction device. Background Art

[0002] Tunnel construction is a complex process, and its environmental pollution is also great. There are many tunnel construction surfaces, long single-entry excavation, large amount of construction dust, and a large amount of dust will be generated during construction blasting. The dust reduction effect is directly related to the construction site. If the construction site is not dusted in time, it will seriously endanger the health of production personnel and affect construction safety and production progress. Therefore, dust reduction equipment is needed to reduce dust.

[0003] At present, traditional dust suppression equipment still has some shortcomings. When suppressing dust, water is usually sprayed out of a nozzle to suppress dust. Since the nozzle is fixed and cannot be adjusted in angle, when spraying at different positions in the tunnel, the entire equipment needs to be rotated to adjust the left and right angles of the nozzle. The process is not only time-consuming and labor-intensive, but also reduces the efficiency of dust suppression in the tunnel. For this reason, we propose a highway tunnel construction dust suppression equipment. Utility Model Content
