What should the car pay attention to when driving in the tunnel?

At present, our car is a very important travel tool for friends and plays a very important role in our travel problems. Of course, the road conditions that cars need to face are also very strange. Friends should watch the road conditions of the tunnel many times. Then, friends don't know what to pay attention to when driving in the tunnel. Today, the car editor will give you a brief introduction.

What should you pay attention to when driving in a tunnel: What should you pay attention to when driving in a tunnel?

1. Pay attention to the warning signs before entering the tunnel.

There are basically tourist signs with width and height restrictions in front of the tunnel. You must read the warning signs clearly and drive according to the regulations. Warning signs are basically scientifically calculated, so you must believe that there is no doubt about following their instructions. If you are not careful, you will have to bear the consequences.

2. Turn on the light in advance.

Some friends think there is a light in the tunnel, so it is unnecessary to turn it on. I think this is wrong. Although there are lights in the tunnel, the light is very weak. If you don't drive, the light will affect your eyesight and you can't see anything in the dark. But be careful not to turn on the high beam, because the high beam will instantly blind the driver's visual experience, which is very dangerous.

3. Keep a safe distance.

Due to the great difference of light when entering and leaving the tunnel, blind spots will appear in the line of sight in a short time, so keeping a large distance between cars can ensure sufficient safety. In most tunnels, the driving distance needs to exceed 100 meters. If the tunnel is long, you need to keep the corresponding safe driving distance according to the prompt.

4. Close the window.

There will be echoes when there are cars passing by in the tunnel, and the echoes will be bigger when there are more cars. If the window is open, it will make people uncomfortable, especially the elderly and children. Therefore, close the windows as much as possible before entering the tunnel.

5. Descend and maintain the specified speed.

When driving in the tunnel, you must slow down, otherwise dangerous accidents will easily occur. Prevent the poor sight of the tunnel from making it difficult for the driver to judge the surrounding specific conditions. Especially when the tunnel is about to exit, it is even more necessary to slow down, because the sunshine at the exit is quite dazzling, and it is difficult for the driver to see the road ahead immediately. Once there is an accident at the exit, speeding will cause tragedy. Therefore, it is necessary to observe the driving situation at the entrance of the tunnel and whistle at the exit immediately to prevent accidents.

6. Don't overtake at will.

Overtaking in a tunnel is very dangerous, especially in a dimly lit tunnel. Forcibly overtaking will cause an accident. Some tunnels are narrow on both sides, so overtaking is easy to hit the side of the road, and accidents will occur if it is not done well.

7. No parking in the tunnel.

Some drivers will pull over for repairs as soon as they are in doubt, but this habit must be prevented when driving in the tunnel, otherwise it will easily affect the serial collision. If there is something wrong with the car in the tunnel, we will try our best to drive it out of the tunnel as long as it can continue to drive; When the car can't leave the tunnel, the people on board must leave the car quickly, try to move the car to the special parking spot, turn on the danger warning light, set up a warning sign at the back of the car 150 meters, and call the expressway management center by emergency phone.

What should you pay attention to when driving in a tunnel: the wonders of the tunnel

The longest two-hole one-way highway tunnel in the world. It starts from Qingcha, Chang 'an District, Xi in the north and reaches Yingpan Town, Zhashui County, Shangluo City in the south, with a total length of18.02km and a design speed of 80km/h.. It takes you 15 minutes to drive across the Qinling Mountains, which is the dividing line between China and the south. This &; Ldquo is the best in the world. Designed and built entirely by China people, the design also embodies the concept of humanization: a special light belt is specially set in the tunnel to show &; Ldquo Blue Sky&; Rdquo & Baiyun. Ldquo Rainbow &; Rdquo waiting can make drivers and passengers feel aloof, which is helpful to relieve driving fatigue.

Shiquling Tunnel in Taiwan Province Province

The earliest mountain railway tunnel in China. June 1887, Keelung &; Mdash & mdash Taipei mdash & mdash Hsinchu Railway runs from Taipei to Keelung, with a total length of 32. 186 km. The following year, the Hsinchu Railway was built from Taipei to the south, with a total length of 67.438+0 km. From Taipei to Keelung, the railway needs to cross Shiqiaoling and dig a tunnel with a length of 26 1 meter. The tunnel passes through shale, sandstone and clay layers, and the maximum buried depth is 6 1 m. At that time, due to the limited funds and technology, the construction could not be carried out simply because of the lack of safety facilities, and many landslides occurred during the construction. Fortunately, when the tunnel finally penetrated, it didn't happen &; Ldquo wears sleeves. Phenomenon (staggered up and down), but the northern end is 4.27 meters higher than the southern end. In any case, the construction of this tunnel has left many valuable construction experiences for future generations [4].

Lodal Tunnel in Norway

The longest single-hole highway tunnel in the world, with a total length of about 24.5 kilometers. It is located in the middle of Norway, starting from Radal in the east and reaching Lu Lan in the west. It is the main throat connecting Oslo, the first basic capital, and Bergen, the second largest city.

In the past, cars traveling between Oslo and Bergen not only had to take a three-hour ferry ride in Rada to cross Qinfjord, but also crossed the steep mountain road between Rada and Ayuliang, which was forbidden during the freezing period in winter. After the opening of the Lodal Tunnel, the travel time between the two places was shortened from 14 hour to 7 hours, and cars were used as usual in winter.

According to the design, the capacity of the Lodal tunnel is 400 vehicles per hour. However, due to Norway's small population, there are only 65,438+0,000 vehicles passing through the tunnel day and night, which is only one tenth of the design flow.

Saint Gotha tunnel, Switzerland

The longest car tunnel in the world, with a total length of 16.32 km. This tunnel spans the St. Gotthard Peak in the Alps in the southeast of Zurich and is an important hub connecting the north-south trunk line of the Swiss state-owned expressway system.

Many technical problems have been encountered in the design and construction of the tunnel. The tunnel needs to pass through granite, gneiss, schist and other strata, and the worst section is weathered gravel and talc. In order to facilitate ventilation, drainage and slag discharge, a parallel pilot tunnel is excavated at 30 meters on one side of the tunnel, and a horizontal communication channel is set every 250 meters to communicate with the tunnel, which can also be used to build a second tunnel in the future.

In the fire protection design, the top of the tunnel is divided into air inlet and air outlet. In case of fire, transverse ventilation can be carried out in sections, which has nothing to do with other ventilation areas. There are also computer adjustment stations at both ends of the tunnel to monitor and adjust the traffic flow, and give immediate warning of changes in air cleanliness, fire and lighting brightness.

Guanyue tunnel in Japan

The earliest super-long highway tunnel was built. In view of this, the Japanese government has also promulgated &; Commemorative activities for the opening of ldquo; Stamps commemorating the longest highway tunnel in Japan.

The tunnel connects Gunma County and Niigata County with a total length of 10.9 km. It runs through the Tanigawa Mountains, with steep peaks and snow all year round. In order to avoid the collapse of snow on the top of the mountain and block the entrance of the tunnel, the tunnel adopts the way of lining extension. In addition, the technicians also adopted advanced tunnel equipment, designed and changed the horizontal ventilation mode commonly used in long tunnels, and took the lead in adopting the vertical ventilation mode combining electrostatic dust removal with shaft, which reduced energy consumption and achieved obvious results.

Is it necessary to read the introduction of the car system before you know what to pay attention to when driving in the tunnel? So, do your friends like the knowledge that Bian Xiao Auto introduced to your friends today? Che Bianxiao believes that these content knowledge partners must have a good understanding, which is basically our problem. Finally, I hope that the introduction of automobile system can solve the problem for friends.
