Description

Technical Field

[0001] The utility model relates to the technical field of safety warnings, in particular to a safety warning device for tunnel construction. Background Art

[0002] A tunnel is an engineering structure buried in the ground. It is a form of human utilization of underground space. During tunnel construction, personnel need to enter the tunnel. Since various dangers are very likely to occur during tunnel construction, various warnings need to be given to workers at different locations to warn them to work safely.

[0003] Through searching, it is found that a tunnel construction safety warning sign with announcement number: CN219430592U, through the coordinated use of the adjustment component, the main component and the alarm component installed on the base, can effectively warn passing pedestrians and vehicles through alarm sounds and alarm lights of different colors. It can also have a good warning effect on pedestrians with poor eyesight, avoiding the occurrence of safety accidents caused by poor warning effects. At the same time, the warning sign can be adjusted to the required height according to the different conditions of the construction location and environment, thereby greatly improving the safety performance of the use of tunnel warning signs. However, a device similar to the above-mentioned tunnel construction safety warning sign is usually a static light, which is easy to cause staff to ignore it, thus affecting the safety of staff during tunnel construction.

[0004] To this end, we provide a safety warning device for tunnel construction to solve the above problems. Utility Model Content
