Anhai Bay Cross -sea Bridge: The first no -orbital rail cross -sea cable -stayed bridge

On August 4th, my country's first high -speed rail no -rail -free orbit cross -sea cable -catching bridge -Fuxia High -speed Railway Bay Bridge completed the construction of no orbit. This is also a major breakthrough in the high -speed rail cross -sea cable -stayed bridge. The Antai Bay Bridge is located in Quanzhou City, Fujian Province. It is connected to Jinjiang City and Nan'an City in the jurisdiction. The total length is 9.46 kilometers. Among them, the cross -sea section is 1.56 kilometers long, the main bridge is 300 meters, and the main channel of the 2,000 -ton mainway of the Anwan Bay is across the main channel. It is one of the key control projects on the entire line. The main bridge is the two -tower dual cable surface and the semi -floating system steel mixed binding beam cable -stayed bridge. This is the first time in my country's high -speed rail construction in the cross -sea cable bridge. It is laid on a rail -free orbit to achieve a high -speed rail train with a speed of 350 kilometers per hour without deceleration. It takes less than 7 seconds to drive the 650m main bridge. According to reports, the high -speed rail rails are divided into two forms: "there are 砟" and "no 砟" orbit. In contrast, the flatness of no orbit is higher and the stability is stronger. And through the "no" orbit, "like the flat ground." However, because the technical bottleneck limits the application of the non -span bridge, most of the domestic high -speed rail large -span bridges mostly use the "砟" track.

Quanzhou Bay Cross -sea Bridge: R & D and successfully applied a variety of construction methods

On July 4th, the construction of the cross -sea bridge of the Quanzhou Bay Bridge was completed. The Quanzhou Bay Cross -Sea Bridge was located in Quanzhou City, with a total length of 20 kilometers, the construction length of the sea area was 9 kilometers, the main bridge was 800 meters long, and the main cross was 400 meters. The tower dual -cable -faced steel mixed combination beam semi -floating system holds the cable bridge. The quality of no orbiting is the key to ensuring the safe and stable operation of the train. The non -oligraphy -free orbit used as a concrete structure is required to be formed at one time. It has the characteristics of high accuracy and strong operating connection. In order to ensure the construction accuracy of the large -span multi -joint special structure bridge at sea, the project team has developed and successfully applied to the complex environmental characteristics of the maritime environment. Windproof method of fine -tone, cross -seal high -speed rail cable -bearing bridge double -block without orbit line -shaped control construction method.

Meizhou Bay Cross -sea Bridge: The first domestic cross -sea high -speed rail dwarf tower cable bridge

On April 15, the Meizhou Bay cross -sea bridge was smoothly paved. The Meizhou Bay Cross -sea Bridge is located in Putian City and Quanzhou City. It is 14.7 kilometers in length. Among them, the construction length of the sea area is 10.8 kilometers and the design speed is 350 kilometers per hour. The whole bridge uses a CRTS I -type dual -block without orbit with a design speed of 350 kilometers per hour. According to reports, the Meizhou Bay Cross -sea Bridge -Bridge Rail Pinerials use a new type of rail paving units independently designed and developed by the China Railway 11th Bureau Group. The characteristics of small processes and flows and wide range of applications have filled the technical gap in my country's high -speed rail mechanized cross -line rail paving. At the same time, in response to the characteristics of many cross -rail crossing construction and long transportation distance, the Meizhou Bay Cross -sea Bridge Rail Pavening also uses the most advanced domestic layout comprehensive command management scheduling system. Positioning, scheduling command intelligent screening and other functions can monitor long -track installation and unloading conditions in real time, car trajectons along the way locomotive and vehicles, and “overtime” for 500 -meter long rail transportation and construction safety. The first domestic cross -sea high -speed railway is expected to open in 2023

According to reports, the Fuxia high -speed rail is the first domestic cross -sea high -speed rail. From Fuzhou City in the north, to Xiamen and Zhangzhou in the south, the total length of the main line is 277.42 kilometers, and the design speed is 350 kilometers per hour. Quangang, Quanzhou East, Quanzhou South, Xiamen North, and Zhangzhou 8 stations. As an important part of my country's "eight vertical and eight horizontal" high -speed railway network, there are 85 bridges and 33 tunnels on the Fuxia high -speed railway, which have crossed the three bays of Meizhou Bay, Quanzhou Bay, and Anhai Bay. The entire line is expected to open operations in 2023. After the opening of the Fuxia high -speed railway, Fuzhou and Xiamen will form a "one -hour life circle". Xiamen, Zhangzhou, Quanzhou and other places will form a "half -hour transportation circle". Golden Tourism Belt. In the future, the Fuxia High -speed Railway will also inject new momentum into the accelerated rise of the two major metropolitan circles of Fuzhou and Xiamen Zhangquan and the regional economic and social development along the line.
