Building a milestone super project, China's first cross -sea cable -catching bridge, the West is incredible

Bridge

China's infrastructure is a hot topic in the world. With the rapid development of the domestic economy and the overwhelming of various infrastructure projects, these infrastructure projects not only benefit the country's economic and social development, the people's travel is convenient, but also shows the strength of the country. Nowadays The country has created another milestone super engineering. China's first cross -sea cable -catching bridge was born. The West was incredible. It was the first Chinese cross -sea bridge in China near the strait, the Pingtan Strait Gongtie Bridge.

Bridge

Pingtan Strait Gong Railway Bridge, located in Fuzhou City, Fujian Province, will be the longest Straits Gong Railway Bridge in the world. This bridge is 16.34 kilometers in length. In Su'ao Town, Tanxian, the down -level design speed is 200 kilometers per -level first -class railway. The upper -level design speed is 100 kilometers per hour. The total investment of the project is 14.7 billion yuan. The time and space distance, formed a half -hour life circle.

Bridge

Pingtan Bridge starts in Panasonic Town, Changle City, Fujian, via Renyu Island, Changyu Island, Xiaoming Island, and Dacian Island. In order to build this big bridge, 1,100 tons The beam lifting machine, set up a 452 -ton steel box beam at the designated location. The Pingtan Strait where this bridge is located is one of the world's large air outlets. The above strong winds for more than 300 days, and 200 days above level 7, once known as the "bridge restricted area".

When the rocks on the bottom of the sea are also very high. When the construction team hit the first steel pipe pile into the depth of the sea rock, the pile head was squeezed to distorted. However, Chinese experts imagined the method of piling of four legs. The four groups of steel pipe piles were put into rocks and connected with concrete and reinforced cages. So independently develop a hydraulic dynamic head rig.

Because it is the wave flow power of the construction of the bridge, it is more than 10 times that of the bridge of the Yangtze River in the Yangtze River. Therefore, the construction is huge and the risks are high. Due to the harsh construction environment, the conventional loose part installation method cannot meet the needs of construction. Construction risks, specialized in large -scale, factorized installation. In order to hang the pores of 1,350 tons of steel box beams, it specially spent 340 million to create a bridge -building artifact "Bridge Seagull" from Airlines. Among them, the capacity reaches 3600 tons.

In order to build this bridge, another bridge -making artifact was also tailor -made. The 2000 tons of fully closed the sea bridge manufacturer and created a hundred -meter -sized air promenade at sea. The construction staff can operate in the promenade and build it to build a construction and build it. The bridge has experienced 7 years, and finally opened to traffic in 2020. This bridge is only 68 nautical miles away from Hsinchu, Taiwan. This distance is built on the high -speed rail tunnel under the sea. With the current infrastructure technology in China, there should be no problems. Pingtan Bridge Bridge. It is the foundation of the Beijing -Taiwan high -speed rail.
