Framed Modular Tunnel Facade Marking

Abstract

The invention discloses a modular frame-type tunnel facade marker, which comprises a curb main plate fixed on the curb and a wall edge main plate fixed on the wall, and the curb main plate and the wall edge main plate are provided with In the maintenance channel, the curb main plate is composed of several rectangular curb modules with the same size and with elevation markings spliced ​​from the entrance to the exit on both sides of the tunnel, and the wall main module is composed of several and uniformly distributed wall edge modules; the frame type tunnel facade mark of the present invention adopts a modular structure, which is simple to install and low in cost, and is connected independently by each plate, and can be quickly extracted and replaced at any time if the vehicle is damaged due to collision, so that it is always Maintain an ideal technical state. The reflective sheet or reflective film on its surface is relatively smooth. If it is dirty during normal use, it can be washed and cleaned with a sprinkler. It is very convenient for daily maintenance.

Description

technical field [0001] The invention relates to a frame-type modular tunnel facade marker, which belongs to the technical field of traffic safety facilities. Background technique [0002] Although the setting of façade markings occupies a small proportion in traffic safety facilities, its role cannot be ignored, especially when vehicles are driving on expressways and first-class road tunnels, the speed of vehicles is faster and the safety sight distance is shorter , the tunnel walls on both sides are darker, which will greatly reduce the safety of driving. Therefore, in order to achieve the purpose of improving the safe driving coefficient in the tunnel, it is one of the effective means to continuously set larger framed tunnel facade marks, which can increase the safety of traffic. The reflection of car lights enables the driver to understand the overall line shape and frame of the tunnel in advance, and the additional vehicle distance confirmation signs on both sides use th...

[0002] Although the setting of façade markings occupies a small proportion in traffic safety facilities, its role cannot be ignored, especially when vehicles are driving on expressways and first-class highway tunnels, the speed of vehicles is faster and the safety sight distance is shorter , the tunnel walls on both sides are darker, which will greatly reduce the safety of driving. Therefore, in order to achieve the purpose of improving the safe driving coefficient in the tunnel, it is one of the effective means to continuously set larger framed tunnel facade marks, which can increase the safety of traffic. The reflection of car lights enables the driver to understand the overall line shape and frame of the tunnel in advance, and the additional vehicle distance confirmation signs on both sides use the distance between vehicles as a reminder to the driver to maintain a safe distance between vehicles and predict and measure danger. , the current application of tunnel facade markings, especially the facade markings facing the outer edge of the maintenance channel, mostly adopts the application method of painting reflective paint. Dust, mud, and car exhaust splashed in the inner tunnel often appear dirty, corroded, peeled off, and damaged by friction, which requires constant repainting, which has a high overall cost and is difficult to achieve ideal application effects
