Problems solved by technology

[0005] What the present invention aims to solve is that high lighting brightness is required at the entrance and exit of tunnels, so high-intensity and high-energy-consumption lighting equipment is used, resulting in huge energy consumption in tunnel operation and management, and it is difficult to achieve and meet the requirements of my country's "Energy Conservation Law". In order to solve the problem of the first requirement, a grating barrier for the entrance and exit of the tunnel is provided, which is designed according to the principle of human vision, mechanically adjusts the adaptability of human vision, and avoids the phenomenon of visual blindness at the entrance and exit of the tunnel, thereby avoiding or reducing the tunnel entrance and exit. Illumination settings for

Embodiment 1

[0029] Embodiment 1: Tunnel entrance and exit grating barrier, the barrier is installed along the road surface at the entrance and exit of the tunnel 3, the barrier is composed of a bracket 1 and a mask 2, the bracket 1 is square, and the mask 2 is set on the top of the bracket 1 by a long block Composition, the distribution of long strips at the outer end of bracket 1 is relatively sparse, and the distribution of long strips at the inner end of bracket 1 close to the tunnel mouth is denser, so that more light comes in from the outer mask 2, while the light coming in from the inner mask 2 Less, to ensure that the pupils can gradually adapt to the brightness in the tunnel from the outside to the inside, and the middle of the bracket 1 is connected with the tunnel to ensure the passage of vehicles.

[0030] The speed limit of the tunnel 3 is 20 kilometers per hour, so the fence is divided into three sections. The length of the fence from the tunnel entrance is 10m, the length of ...

Embodiment 2

[0031] Embodiment 2: Tunnel entrance and exit grating barrier, which is installed along the road at the entrance and exit of the tunnel. The barrier is composed of a bracket 1 and a mask 2. The bracket 1 is square and rises step by step from the outer end to the inner end near the tunnel entrance. It is distributed in a ladder shape, and the mask 2 is a plate with mesh, which is arranged on the top of the support 1. The distribution of the mesh at the outer end of the support 1 is relatively sparse, and the distribution of the mesh at the inner end of the support 1 close to the tunnel entrance is relatively dense, so that from the outer end More light comes in from the mask 2, while less light comes in from the inner mask 2, ensuring that the pupils can gradually adapt to the brightness in the tunnel from the outside to the inside, and the middle of the bracket 1 is connected to the tunnel to ensure the passage of vehicles.

[0032] The speed limit of the tunnel 3 is 40 kilomet...

Embodiment 3

[0033] Embodiment 3: Tunnel entrance and exit grating barrier, the barrier is installed along the road at the entrance and exit of the tunnel, the barrier is composed of a bracket 1 and a mask 2, the bracket 1 is arched, and the mask 2 is set on the top of the bracket 1 by a long block Composition, the distribution of long strips at the outer end of bracket 1 is relatively sparse, and the distribution of long strips at the inner end of bracket 1 close to the tunnel mouth is denser, so that more light comes in from the outer mask 2, while the light coming in from the inner mask 2 Less, to ensure that the pupils can gradually adapt to the brightness in the tunnel from the outside to the inside, and the middle of the bracket 1 is connected with the tunnel to ensure the passage of vehicles.

[0034] The speed limit of the tunnel 3 is 60 kilometers per hour, so the barrier is divided into three sections. The length of the barrier from the tunnel entrance is 30m, the length of the mi...

Abstract

The invention discloses a grating barrier at tunnel exit and entrance, relates to the technical field of engineering, and particularly relates to energy conservation technology applied to road tunnel engineering. The grating barrier at the tunnel exit and the entrance is characterized in that barriers are respectively mounted at the tunnel exit and the tunnel entrance along a road surface, each barrier consists of a support and barrier plates, each barrier plate is disposed on the top of the corresponding support, vehicles run through the middle of each support, and the barrier plates of each barrier are arranged in such a manner that light transmissions of the barrier plates are gradually increased from the tunnel exit or the tunnel entrance to the outside. The barriers are designed according to the human vision theory, adaptability of human vision of a person is adjusted mechanically, vision blindness is avoided when the person enters or leaves away from the tunnel via the entrance or the exit, and accordingly the requirement on illumination of the tunnel exit and the entrance can be reduced on the basis that safety is guaranteed.

Description

technical field [0001] The invention relates to the field of engineering technology, in particular to an energy-saving technology applied in road tunnel engineering. Background technique [0002] There are pupils in human eyes. When the main light and reflected light enter our human eyes, the pupil size of the eyes will automatically adjust, especially when affected by the strong light and darkness of the outside world, the pupils of the eyes will become smaller or larger. Reduce the amount of light entering the eyes or improve clarity; when the external light is weak, the pupil will become larger to increase the amount of light entering the eyes, allowing us to see the environment and objects better. However, the adjustment of the pupils needs a certain process. When we go from a dark place to a bright place, or from a bright place to a dark place, the pupils have not been adjusted properly in a very short time. Therefore, at that moment, the eyes are easily stimulated, re...
