Problems solved by technology

[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 opening; the outline of the tunnel opening is less obvious at night
Affect the driver's judgment, there is a certain safety hazard

Embodiment Construction

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

[0011] Said reflective ring production installation:

[0012] (1) Reflective rings on the inner and outer contours of the tunnel entrance: use hard materials such as aluminum plates, steel plates, steel-plastic boards and other hard materials to make reflective ring bottom plates according to the circular arcs of the inner and outer contours of the tunnel entrance, and then paste passive As for the reflective material, fix the reflective ring on the inner and outer contour surfaces of the end of the tunnel opening by anchoring.

[0013] (2) Reflective ring on the inner contour of the tunnel hole: use hard materials such as aluminum plate...

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...
