Ten special projects in China

1, Hangzhou Bay sea crossing bridge
The Hangzhou Bay Bridge is a bridge across the Chinese Zhejiang Hangzhou bay cross sea bridge, north of Jiaxing City, Zhejiang province Zheng Jia Dai, Haiyan, Ningbo city in the south of Cixi Bay waterway. The Hangzhou Bay sea crossing bridge is the second bridge across the sea after China's reform after the Nanpu bridge in Pudong, Shanghai. The bridge can be passed from Ningbo to Shanghai. The Hangzhou Bay Bridge a total length of 36 kilometers, than between Bahrain and Saudi King Fahd bridge is 11 kilometers long, Chinese held the world record association the world's longest cross sea bridge is a bridge to the world record, after the United States of the Lake Pontchartrain bridge and Qingdao Jiaozhou Bay Bridge is the third longest in the world.

In the South Channel 1.7 kilometers south, about 14 kilometers from the south bank, there is a sea platform with an area of 12 thousand square meters. The platform in the sea is a rescue platform for traffic services in the sea, and it is also an excellent tourist resort.

2, Henan / Shanxi Wall Road
The hanging wall road is one of the most distinctive highways. It is a dangerous highway that is cut out on the cliffs. Traffic experts say such projects are rare and difficult, and are rare in the history of China's road construction. In order to facilitate the construction and opening of natural lighting, Wall Road multi wall and chisel, separated by more than ten meters next to open the side of the window. From a distance, the frontline window outlines the direction of the tunnel.
There are seven hanging wall highways in the South Taihang Mountain area in the southeast of Jin Dynasty. Taihang mountain high and low in the south, the East West steep relief, the west wing is connected with the Shanxi plateau, east of the obvious fault, many areas formed nearly 1000 meters of fault rock, imposing. There are many rivers in Taihang Mountain, which are originated or flowed through, causing the continuous mountains to break down and form "water outlets". Most of them are waterfalls due to the fault wall. Only a few of them have smaller slopes. "Water outlet" can become a key way for the North China plain to enter Shanxi plateau. The hanging wall road is built on the fault cliff of the North China plain to the Shanxi plateau.
Lingchuan, Shanxi: Tin cliff hanging wall Road, Chen home wall Road, Kunshan hanging wall road Shanxi flat: Hong ladder wall Road, the bottom of the wall Road
Henan, Huixian: Guo Liang Wall Road, Huilong village wall road.
The largest amount of engineering, the earliest excavated to be the tin cliff wall hanging wall road. The road is the most famous, because it stretches nearly 8 kilometers, the largest amount of engineering, the longest time, the appearance is divided into three layers, the most magnificent. More importantly, it is a pioneer in the Taihang Mountains in the hanging wall of highway, is xiyagou people with a hammer, drill rod, a Wall Street on her hands on the cliff cutout! The "tin cliff gully Wall Road" has also become the only country grade highway that has been incorporated into the "China road spectrum", which is called the Ninth Wonder of the world!

1. Shaanxi Qinling Mountains Zhongnanshan highway tunnel
   The Zhongnan Mountain Highway Tunnel in Qinling Mountains, Shaanxi is 18.02 kilometers long, and the two holes are 36.04 kilometers long. They can be crossed in 15 minutes, and Xi'an to Zhashui shorten from 3 hours to 40 minutes. In January 20, 2007, Qinling Mountains Zhongnanshan highway tunnel opening ceremony was held, thus restricting the economic development of Qinling Mountains's into a thoroughfare. The construction of Qinling Mountains Zhongnanshan highway tunnel is the first in the world, and the most of the highway tunnel in China. After the leardo highway tunnel in Norway is 24.51 kilometers long.
   It is understood that the Qinling Mountains Zhongnanshan tunnel has created six of the most China Highway Tunnel Construction: the world's first single hole double hole highway tunnel, a total length of 18.02 kilometers; the first to design, construction and supervision by China, and the highest level of comprehensive management, the world largest caliber, the depth of the tunnel; the highest shaft ventilation engineering has the most comprehensive monitoring system; world highway; special highway tunnel lighting the world's most advanced zone; first proposed strategy management theory, using the first strategy of software automatic generation, automatic monitoring and management of fire, traffic accidents, maintenance etc.. In this sense, the technical significance of the Qinling Mountains Zhongnanshan tunnel is not only Shaanxi, but also the world.
   Go from Qinling Mountains Zhongnanshan tunnel north, South 18.2 kilometers across Qinling Mountains can. Qinling Mountains Zhongnanshan tunnel, designed at a speed of 80 kilometers per hour, takes about 15 minutes to complete the journey. In these 15 minutes, you can feel the difference of this tunnel. Different places, different colors of light, in the tunnel form a light world. And more specifically, you can't take a long walk, and you'll see a bright front in front of you, and it seems to be going to the hole. The clouds are in the sky, and the trees are shaded under the ground. The special light belt in the tunnel is 150 meters long and 20.9 meters in width. It is like a small small park in the tunnel.
   
   4, Hunan low village Panshan highway

This particular space forcing the road number of turns, forming 13 sharp sharp, almost parallel, 26 section of pavement under the overlapping. The width of the road is not more than 7 meters, the narrowest section is less than 4 meters, and two cars can not pass at the same time in the narrowest section. It is said that during the construction period, we first cut out a strip of steps on the slope of Dashan, then connected the two ends of the stairs. If we couldn't connect them, we would set up a "flyover" or suspend a circular turntable to make the car turn into an "infinity". The low village road is also a compound line of 209 and 319 by the national road.
