Problems solved by technology

[0003] In order to ensure that the driver can observe the environment in the tunnel well, there are generally a large number of lighting lights in the tunnel, but at present, when the external brightness changes greatly, the phenomenon of "black hole" or "white hole" will appear in the human eye , the best way to avoid this situation is to adjust the brightness of the lighting in the tunnel to reduce the gradient of light brightness. This situation leads to a small difference between the light intensity at the tunnel entrance and the outside world, and the light intensity gradually decreases as you go deeper into the tunnel. In this way, although the driving safety of the driver can be ensured, maintaining high-brightness light all the time will make the power consumption of the lights in the tunnel larger, making the operation and maintenance costs of the tunnel higher

Embodiment Construction

[0025] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0026] Such as Figure 1-3 As shown, a tunnel-combined road guardrail and its use method include a support column 1, a plurality of support columns 1 are provided, and the top of the support column 1 is fixedly connected to the ground.

[0027] And the top of the support column 1 is fixedly connected with the light guide sleeve 2, such as figure 2 , image 3 As shown, the light guiding sleeve 2 is composed of a housing 21 , a light guiding cavity 22 and a light entering layer 23 .

[0028] The light guiding cavity 22 is located inside the housing 21, the inner wall of the light guiding cavity 22 is a light-reflecting structure, the light-introducing layer 23 is arranged on the top of the light-guiding cavity 22, and the light reflected by the refractive layer 3 will enter the light-guiding layer 23 cavity 22.

[0029] The light entering layer 23 is ...

Abstract

The invention belongs to the field of road engineering, and particularly relates to a tunnel combined type road guardrail and a using method thereof. The tunnel combined type road guardrail comprises a plurality of supporting columns, light guide sleeves are fixedly connected to the top ends of the supporting columns, refraction layers are fixedly connected to the top ends of the light guide sleeves, and light condensation layers are fixedly connected to the top ends of the refraction layers; a cleaning mechanism capable of cleaning the light condensation layer is arranged on the outer side of the refraction layer, and one side of the light guide sleeve is connected with a light emitting mechanism arranged in the tunnel. According to the tunnel lamp, external light rays are subjected to condensation, reflection and other operations, reinforcement of the light rays in a tunnel is achieved, the phenomena of white holes, black holes and the like when vehicles enter and exit from the tunnel can be avoided, electric energy does not need to serve as energy, and therefore energy can be greatly saved.

Description

technical field [0001] The invention belongs to the field of road engineering, and in particular relates to a tunnel-combined road guardrail and a method for using the same. Background technique [0002] Tunnel is an engineering building buried in the ground, and it is a form of human use of underground space. Especially in mountainous areas, tunnels can greatly reduce the driving distance and improve the driving time between different regions. [0003] In order to ensure that the driver can observe the environment in the tunnel well, there are generally a large number of lighting lights in the tunnel, but at present, when the external brightness changes greatly, the phenomenon of "black hole" or "white hole" will appear in the human eye , the best way to avoid this situation is to adjust the brightness of the lighting in the tunnel to reduce the gradient of light brightness. This situation leads to a small difference between the light intensity at the tunnel entrance and th...
