Description

Tunnel access construction for natural light adaptation {Tunnel Access Construction for Sunlight Adaptation}

The present invention relates to a tunnel access structure, and more specifically, to adapt the visual disturbance of the driver caused by the difference in daytime brightness at the entrance and exit of the road tunnel for vehicle communication by using natural light, thereby acclimatizing at the entrance of the tunnel. And it relates to a tunnel entry and exit structure for the natural light compliance to facilitate the natural light compliance when entering the tunnel.

In general, in the case of Korea, the mountainous area has more regional characteristics than the narrow land area, and in the mountainous areas intersecting between the road networks for smooth communication of the vehicles, they are striving to expand the road networks by drilling tunnels through them. Currently, about 1% of roads are tunnels in the national road network.

In the case of such road tunnel section, the lighting is installed inside the tunnel, but the brightness due to outdoor natural light during the day is about 100,000 lux in normal climatic conditions and reaches at least 50,000 lux. When the driver enters or exits from the tunnel, the driver's visual impairment is inevitably caused by the difference in luminance in the outdoors and in the tunnel.

The visual impairment caused by the driver when entering the tunnel or entering the tunnel often causes a decrease in cognition in front of the vehicle, which drastically decreases the driving speed of the vehicle, which causes traffic congestion on the road. Concerns have increased, and even if statistics show that 38.5% of all collisions in the vehicle are occurring at the tunnel entrance, the damage caused by visual impairment is severe.

In order to solve this problem, as shown in FIG. 1, a predetermined distance between the entrance side and the exit side of the tunnel is divided into a visual lighting compliance section of the driver, and a large amount of lighting is installed at the divided entrance and exit. By doing so, the vehicle driver's visual compliance is ensured during the day.

However, in the case of a method of ensuring a visual compliance by intensively arranging a large amount of lamps at the entrance and exit side of the conventional tunnel, the power energy required for the lighting of the tunnel lamps is greatly increased, and in reality, about the total tunnel maintenance cost As more than 60% of the cost is concentrated, a problem arises that there is considerable inefficiency in terms of managing the cost of the tunnel.

In addition, in order to ensure the driver's visual compliance, a large amount of lighting is installed at the entrance and exit of the tunnel to achieve intensive lighting, but there is still a great deal of difference in the illuminance of natural light that is at least 50,000 lux and usually above 100,000 lux. Because of this, there is a problem that does not normally provide adequate visual compliance to a driver with a variety of vision conditions, such as a driver with severe astigmatism or an elderly driver.

However, the natural light adaptation structure of the tunnel entrance and exit according to the present invention corresponds to the structure applied to both the entrance and the exit of the road tunnel, but in order to help convenience and understanding in the description of the configuration of the present invention, The natural light adaptation structure to be applied will be described as an example. In addition, it is apparent that the natural light adaptation structure for the tunnel exit of the present invention is made of the same configuration, although the design dimension relationship between the natural light conformation structure of the tunnel entrance described below and the accessory is different.

As shown in Figures 2 to 4, the natural light adaptation structure of the tunnel entrance and exit according to the present invention, a predetermined distance from the shaft 45 of the tunnel entrance along the vehicle driving road 10 extending toward the interior of the tunnel As long as the dome-shaped structure for natural light compliance is arranged fixedly.

The support fence 20 is fixedly installed on the ground by extending the support fence 20 from the both sides of the road 10 to the shaft of the tunnel inlet along the driving direction of the road, The front end of 20) is curved in a dome shape and is fixedly coupled to both ends of the inlet frame 25 supporting the inlet of the structure.

In addition, the roof 30 extends long to the shaft 45 of the tunnel entrance along the traveling direction of the road 10 in the upper portion of the dome-shaped structure from the entrance frame 25 to the shaft 45 of the tunnel entrance. It is.

On the other hand, in the natural light adaptation structure of the present invention to gradually reduce the luminance difference from the natural light to the illumination light inside the tunnel to improve the driver's visual compliance using the natural light, both ends of the roof 30 and both sides of the road The distance between the support fence 20 of the to gradually decrease until the shaft 45 of the tunnel entrance from the inlet frame 25.

That is, the roof 30 has the highest height from the inlet frame 25 side to the ground, and on the shaft 45 side of the tunnel entrance, the roof 30 can be connected to or close to each support fence 20. It is designed to have the lowest height.

Here, between the support fence 20 on both sides of the road 10 and the roof 30 on the upper part of the structure, a plurality of connecting members 40 are fixedly coupled at regular intervals along the traveling direction of the road 10. Each of the connecting members 40 corresponds to a state in which the height from the ground of the roof 30 decreases from the side of the inlet frame 25 toward the entrance of the tunnel, and thus, as the connecting members 40 of different lengths. Is placed.

Specifically, as the length of the connecting member 40 on the side of the inlet frame 25 is closer to the entrance of the tunnel, the connecting member 40 is gradually shorter. This is because the space area between each of the connecting members 40 decreases as the entrance to the tunnel becomes smaller, so that the amount of light of the sunlight incident through the space between the connecting members 40 gradually decreases, thereby accommodating the driver's vision. This can be done naturally.

In addition, the plurality of connecting members 40 may be fastened by using fastening members such as anchor bolts when fixedly connecting the roof 30 and the support fence 20.

In addition, a plurality of solar cell panels 35 which receive solar light along the entire area of the roof 30 are generally disposed and fixed in a lattice shape as a whole. The solar cell panel 35 Is disposed in a state in which the power generation facility configuration and wiring are made so that the light energy incident from the solar light is supplied to the power generation facility configuration to be applied to the present invention to produce power energy.

Here, the solar cell panel 35 generally disposed on the roof 30 is fixed to the upper portion of the support (not specifically shown in the drawing) that is disposed in a dome shape while forming the base of the roof 30. The support is made of a transparent material having excellent permeability to transmit the direct sunlight of the sun without loss. The transparent material is excellent in permeability and robust to withstand heavy loads, and has low strain due to climate change. It is preferable to form a high strength synthetic resin material such as polycarbonate, hard polyethylene, or the like.

The plurality of solar panels 35 apply a panel of semi-transparent material that can project only a portion of sunlight, considering the amount of daytime solar radiation according to the site conditions of the tunnel where the natural light-compliant structure is installed. The throw ratio is determined, and it is preferable to provide a solar cell panel 35 made of a semi-transparent material manufactured to match the throw ratio.

Each solar cell panel 35 is a tunnel site in a region having a large amount of daytime solar irradiation, for example, a semi-transparent panel having a projection rate of 50%, and a tunnel site in a region where the daytime solar irradiation is somewhat less. In the case of, for example, a translucent material having a throw ratio of 70% is applied.

In addition, the plurality of solar panels 35 may be installed as a panel of translucent material having the same throwing ratio along the entire area of the roof 30, and the roof 30 is formed at an entrance section (for example, the roof 30). ) A certain portion of the front surface, 1/5 of the total area of the roof 30), the basic section (for example, the central portion of the roof 30, 3/5 of the total area of the roof 30), the entry section (for example the roof 30) Specific areas, such as a certain portion of the rear, 1/5 of the entire area of the roof 30), and apply semi-transparent materials having different projection rates of sunlight in each divided section (for example, the entrance section applies a 70% throw ratio, It is also possible to set the base section at 50% throw rate and the entry section at 30% throw rate.

On the other hand, the installation height, the installation angle, the installation length, etc. of each accessory facility constituting the natural light adaptation structure according to the present invention, the regional characteristics of the tunnel in which the natural light compliant structure is installed (natural light conditions by season, weather changes) and environment It is determined through various virtual simulations in consideration of the enemy characteristics (the terrain state around the tunnel, the state of roadside trees), the traffic volume of the driving vehicle, etc. The design numerical relationship of the accessory equipment of the structure is shown in FIG. As shown.

As shown in FIG. 5, in the natural light compliant structure of the present invention, the entire length (t) of the structure from the end of the entrance frame 25 to the rear end portion coupled with the tunnel 45 of the tunnel entrance, and installed at the front end of the structure From the height h1 of the longest connecting member 40, the height h2 of the shortest connecting member 40 installed at the distal end of the structure, the longest height h1 and the shortest height h2 The angle of inclination (θ) from the horizontal plane indicating the degree of decrease in height gradually between and and the light incidence (s) of the solar cell panel 35 installed on the roof 30 are determined. The key design figures are to be determined.

Meanwhile, the design value of the natural light adaptation structure according to the present invention is determined based on the standard value of the tunnel entrance curve curve of the national standard (KS C 3703: 2010) as shown in FIG. 6.

That is, as shown in Figure 6, the standard value for the illumination curve graph of the tunnel entry portion follows the national standard of "KS C 3703: 2010".

According to FIG. 6, the existing tunnel is classified into an entrance lighting section, a basic lighting section, and an exit lighting section. In the existing daytime tunnel with a natural light intensity standard of 100,000 lux in a normal state, In the lighting standard (upper dashed line graph), the maximum illuminance of about 2,500 lux is maintained at a certain distance of the entrance lighting section, and then the illuminance of the illumination light is gradually reduced to 100 lux, which is the standard of the basic lighting section. It can be seen that the difference in illuminance between the entrance shaft of the tunnel and the illumination section of the entrance is very large, which is a serious obstacle to the dark adaptation of the vehicle driver. For reference, the tunnel illumination criteria (bottom dashed line graph at the bottom) at night is set to 30 lux.

However, in the present invention, a compliance facility lighting section corresponding to the distance of the road on which the natural light compliance structure is installed is added to the previous section of the entrance lighting section, and divides the entrance lighting section to classify a predetermined distance from the front as a boundary, and the boundary section. Classify the transition from the rear to the end of the entrance lighting section as transition.

In addition, in the daytime tunnel lighting standard (a thick solid line graph) according to the present invention, the illumination intensity is gradually reduced from 100,000 lux to 100 lux, which is the standard of the basic lighting section, and is adapted to the natural light compliance structure. In the lighting section of the facility, the illuminance of the sunlight is gradually reduced by using an accessory for lowering the illuminance, and in addition to using some of the sunlight that is projected from the outside of the tunnel through the natural light-compliant structure at the boundary part classified in the entrance lighting section. In order to meet the lighting standards, some of the lamps are installed so that the illumination can be gradually lowered. That is, the boundary between the compliance facility lighting section and the entrance lighting section is the natural light using section.

In addition, the remaining transitions classified in the entrance lighting section may gradually reduce the illuminance by using tunnel lights, and as shown in the graph of the drawing, the conventional daytime tunnel lighting criteria (upper dashed line graph) Compared to), it can be seen that the installation distance and the number of installation of the lamps to be installed at the tunnel entrance are greatly reduced.

In addition, the daytime tunnel lighting standard (a thick solid line graph), which is a standard for designing the natural light adaptation structure of the present invention, is a sudden change in illuminance from the natural light illuminance of 100,000 lux to the illuminance of the tunnel base illumination of 100 lux, Without maintaining the same illuminance at a distance, it shows a form of diminishing illuminance with a constant slope, so that the dark compliance of the driver can be greatly improved.

In addition, the daytime tunnel illumination criteria according to the present invention is an illumination criterion for the entrance of the tunnel, the daytime tunnel illumination criteria at the exit of the tunnel can also be applied in a similar standard to the shape of the graph shown in Figure 6, the tunnel exit portion In contrast to the entrance, the illuminance increases to a certain slope, so that the driver's compliance with the tunnel can be greatly improved.
