October 14th news: according to the "Oriental Morning Post" reported that on the 13 day, the Post reporter drove by the world's largest rail cum road deck cable-stayed bridge.

From the elevated across the inter city high-rise, the North South elevated, the inner ring road, central elevated, Xiangyin road tunnel, Wuzhou Avenue, just half an hour, came to the Shanghai Yangtze River tunnel entrance is located at No. five Pudong ditch. In the arc of the entrance ceiling, "Shanghai Yangtze River Tunnel" six red characters in the eyes.

Spacious entrance, on the eastern side of the uplink (Pudong to Chongming) entrance, the west side of the line (Chongming to Pudong) exports. Side by side in the middle of the two tunnel is a glass and concrete partition, which is generally different from the layout of the two mouth. Technical staff said that due to the entrance into the upper reaches of the new wind, the outlet line of the outlet of the wind in the vehicle exhaust, the wall to prevent the two mixed.

Into the uplink tunnel, there is a very bright light transition section, and then forward is a dark tunnel inside the normal lighting, so that people's eyes from the light to the tunnel in the dark can naturally adapt.

The tunnel is set up 3 lanes on the ground, a new painting on the white flag markings, the tunnel above the information board welcome to the Yangtze River tunnel, the green font flashes from time to time. While the two sides of the wall with a white enamel steel plate material, so that the tunnel appears more spacious vision, in the middle there is a blue belt.

Blue belt in the tunnel about 4 km, that is, the entire tunnel in the middle position, both sides have a large map murals, with an abstract way to mark the location of the Yangtze River Bridge and the main road network in Shanghai. Blue belt in the middle of the mural and green belt intersection. According to reports, the blue belt represents the city style, green belt represents the pastoral scenery. Sure enough, after the car through the middle point, 3 km from Changxing Island, 2 km...... Signs appear in the tunnel, the people who told the car from the citrus rich Changxing Island is getting closer.

The tunnel pavement and the slope of the tunnel, a "W" shape of slope, it is designed according to the characteristics of the river, the lowest point from the river about 55 meters. The whole tunnel also shows a curve on the horizontal plane, which effectively reduces the visual fatigue of long distance tunnel. At the top of the tunnel, the fan is turned on, and the vehicle exhaust is discharged through the relay, and the fresh air is brought in. Even if the person is in the deepest part of the tunnel, the air will not be affected. The tunnel every 800 meters there is a tunnel between the two escape routes, each roadway tunnel on the left, every 270 meters to the lower space is also provided with a tunnel exit.

LED lighting for the first time

Can be divided into 10 levels of brightness control

Yangtze River Tunnel for the first time with the existing other tunnel different lighting methods - LED light source, people feel bright moderate.

It is understood that due to the length of the tunnel, and requires 24 hours of uninterrupted lighting, lighting load accounted for the entire energy consumption proportion of 40% to 50% in the tunnel operation, become "energy hungry", while the use of LED lighting can reduce energy consumption 30%. If the Yangtze River Tunnel in accordance with the ordinary fluorescent lighting, power of 989 kilowatts, a skylight lighting power is about more than 20 thousand degrees, while the use of LED lighting, power consumption is equivalent to playing the thirty percent off. Experts told reporters.

Due to the use of advanced monitoring and control technology, the Yangtze River tunnel bridge can be used to detect the working condition of each LED lamp in the tunnel. One of the characteristics of this kind of lamp is to adjust the brightness, no longer need to control the brightness of the tunnel. The Yangtze River Tunnel LED lamp can start from 20% brightness, with the interval of 10% up to adjust, until the brightness of 100%, including the closure, can be divided into 10 levels. This allows the tunnel to maintain a uniform brightness, but also save electricity, such as in the deep place, as long as 60% or 70% brightness is enough.

Out of the tunnel, in front of an open Changxing Island. In Changxing Island, with a service area and a pan highway toll station. According to the new highway number and the name of the set of "G40", "Shanghai Shaanxi high-speed" signs all the way visible. It is reported that, according to the original number of highway network in Shanghai, the Yangtze River Bridge for A14, and the new number is G40". Due to the Yangtze River Bridge to Chongming will continue to extend through the Chong Kai, until the city of Xi'an, so the Chinese name referred to as Shanghai and Shaanxi high-speed".

After the ground connection road in Changxing Island, a Y-shaped tower to see the spectacular lying on the river, flowing through the Yangtze River bridge bridge from the main tower waist, forming a beautiful "S" shaped curve.
