Exit and entrance of tunnel visual coordinate system reference column and reference system
The present invention discloses an exit and entrance of tunnel visual coordinate system reference column and a reference system, and belongs to the traffic engineering technology field. The cross-section of the reference column is circular, the diameter of the reference column is 10 cm, and the height is 1.5 m. A reflective membrane layer wraps on the body of the column and is composed of two membrane layers which have the different colors and are arranged at intervals. The size design of the reference column is reasonable, and the reference column is easy to process and produce. The wrapped reflective membrane layer can play an effective part in visual warning at the exit and entrance of a tunnel. The present invention also discloses an exit and entrance of tunnel visual coordinate system reference column system formed by the above reference column. The exit and entrance of tunnel visual coordinate system reference column system is characterized in that a plurality of reference columns are arranged at the 250m road section outside a tunnel entrance hole and the 300m road section inside tunnel entrance hole, and a plurality of reference columns are arranged at the 300m road section inside a tunnel exit hole and the 250m road section outside the tunnel exit hole; the distance between the adjacent two reference columns is 25m, and the reference columns are arranged at the two sides of a road symmetrically. The reference column system has the advantages of low manufacture cost and simple construction method, etc.
