Description

Technical Field

[0001] The utility model relates to the technical field of traffic facilities, in particular to a tunnel guidance sign for early warning of special road sections. Background Art

[0002] Many mountainous areas in my country have high mountains, deep valleys, steep slopes, rapid currents and complex terrain. When designing routes, they either follow the mountains and rivers or cross the mountains. The main route layouts are along the river (stream), across the ridge, and the ridge line. Therefore, high-fill curve sections, continuous short slope sections, continuous long steep slope sections with small radius flat curves, and sections with poor combination of flat curves and vertical curves are common. Tunnels opened in these special sections need to use guide signs to guide or warn drivers to prevent traffic accidents. A tunnel guide sign with both sight guidance and emergency guidance described in Publication No. CN218116209U is formed by connecting a number of guide sign units along the length direction of the tunnel. The guide sign unit includes a sight guidance plate and an emergency guidance plate. The sight guidance plate and the emergency guidance plate are vertically connected. The sight guidance plate and the emergency guidance plate are respectively covered and installed on the facade and plane of the tunnel inspection road. The sight guidance plate is a plate with a sight guidance mark on the surface, and the emergency guidance plate is a plate with an emergency guidance mark on the surface to achieve the function of emergency guidance. However, the prior art still has the following defects:

[0003] 1. The existing technology connects the sight line guide plate and the emergency guide plate vertically. The sight line guide plate and the emergency guide plate are respectively installed on the vertical surface and the horizontal surface of the tunnel inspection road, which makes it impossible to change the inclination angle of the guide mark and the direction angle of the guide plate, which has certain limitations.

[0004] 2. The guide sign unit of the prior art is fixed on the inspection road by fasteners on the emergency guide plate, wherein the fasteners are expansion screws, which facilitate the quick installation of the guide plate, but will result in the inability to adjust the height. The display effect of the guide sign will be affected by the height of the vehicle, making it impossible for drivers of some small cars to observe the guide sign. Utility Model Content
