Example Embodiment

[0010] The method for displaying the tunnel contour of the present invention is to arrange a reflective ring along the inner and outer contours of the tunnel opening end at the entrance of the tunnel or along the inner contour of the tunnel at any position in the tunnel. The reflective ring is made of passive reflective material.

[0011] Production and installation of the reflective ring:

[0012] (1) Reflective ring for the inner and outer contours of the tunnel entrance: use hard materials such as aluminum plate, steel plate, steel-plastic plate support, etc. to make the reflective ring base plate according to the circular arc of the inner and outer contours of the tunnel entrance, and then paste the passive For the reflective material, the reflective ring can be fixed tightly on the inner and outer contour surface of the end of the tunnel through the form of anchoring.

[0013] (2) Reflective ring inside the tunnel: use hard materials such as aluminum plate, steel plate, steel-p...

Abstract

The invention relates to a tunnel profile display method which is characterized by arranging light reflecting rings along the inner and outer profiles of the end head of a tunnel portal at an entrance of a tunnel or along the inner profile top inside the tunnel at any position inside the tunnel. The light reflecting rings are made of a passive light reflecting material. Light reflecting ring base plates and supports made of hard materials including aluminum plates, steel plates and steel plastic plates, the passive light reflecting material is stuck to the base plates to form the light reflecting rings, and the light reflecting rings are fixed on the tunnel in an anchoring way. With the tunnel profile display method, the light reflecting material is arranged at the inner and outer profiles of the end head of the tunnel portal, at the inner profile inside the tunnel and other positions, so that the profile of the tunnel at the entrance of the tunnel and the inner profile inside the tunnel can be seen. The light reflecting ring at the portal has obvious induction action on the tunnel portal (especially highways at mountain areas) at nights, so that the tunnel portal can be found in time, and vehicles can enter the portal safely.

Description

technical field [0001] The invention relates to a method for displaying the outline of a tunnel. Background technique [0002] With the development of highway construction, there are more and more highway tunnels. Although there are lighting facilities in the tunnel, the outline of the tunnel cannot be clearly displayed in the darker tunnel. The momentary black hole effect is produced when the car enters the tunnel entrance; the outline of the tunnel entrance is even less obvious at night. Affect the driver's judgment, and there is a certain potential safety hazard. Contents of the invention [0003] The purpose of the present invention is to provide a method for displaying the outline of a tunnel, which can clearly display the outline of the tunnel at any position and increase the safety of driving. [0004] The technical solution of the present invention is: at the entrance of the tunnel, a reflective ring is arranged along the inner and outer contours of the end of th...
