They can build cross -sea high -speed rail through the mountains!

Xinhua News Agency, Fuzhou, September 3 (Reporter Zhang Huaying, Linde Ren) Recently, my country's first cross -sea high -speed rail -Xinjian Fu (state) Xiamen (Gate) railway was opened across the line, laying a solid foundation for subsequent operations.

This railway has crossed the three bays of Meizhou Bay, Quanzhou Bay, and Anhai Bay. There are many hills in the mountains and many bridges. The reporter recently entered the construction site of the new Fuxia Railway and visited the little -known story behind the railway.

The sea winds and waves are in a hurry to "see sewing pins" dispatch construction

Since joining the new Fuxia Railway Project in September 2017, Luo Changwei, manager of the No. 2 Branch of the New Fuxia Railway Project of the China Communications Second Airlines Bureau, has developed the habit of viewing the tide and wind of the sea daily. The Quanzhou Bay Cross -sea Bridge, which is held by his team, is the first high -speed high -speed railway bridge with a 350 -kilometer -speed 350 kilometers per hour in China, with a total length of 20.29 kilometers, of which the sea bridge alone is nearly 9 kilometers.

Quanzhou Bay, where the cross -sea bridge of Quanzhou Bay is located, is located in a high -winds belt along the coast. The air conditions and the hydrological environment of the sea are complicated. The average number of winds and more wind power of the year is 48 days, up to 84 days. Bring a lot of challenges. "In the years of construction, the wind on the bridge has hardly interrupted. July to September each year is the typhoon season, and the autumn and winter seasons are during the monsoon period."

Facing the harsh operation environment of the wind and waves, seeing the construction of the stitches has become the norm of working in the Luo Changwei team. Luo Changwei said: "We need to collect seawater upward tide time, sea wind level, and waves of waves every day in order to accurately reach the construction time to a certain time period."

Luo Changwei introduced that in the limited construction time, in addition to the scientific and reasonable organizational construction and optimizing the on -site construction technology, they must also continue to increase investment in personnel, materials, and machinery and equipment to ensure on -site construction progress. "During the peak of the project construction, there were more than 2,000 workers on the spot, and more than 130 special equipment such as tower cranes used."

Borrowed Internet of Things technology to eliminate "blind hanging" security risks

The large amount of investment in artificial, materials, and machinery has also put forward higher requirements for construction safety and intelligence. Take special equipment tower crane as an example. In high -pier and complex environments, the tower crane driver is often difficult to see the specific situation under the hook. It can only be operated under the command of the ground division. Hanging.

Yao Xiangyang, Secretary of the Party Branch, Secretary of the Party Branch of the 4th Five Industry Zone Project Department of the China Railway Eleventh Bureau, which is responsible for building the Meizhou Bay Cross -sea Bridge project, said that in order to eliminate the safety risks brought by the "blind hanging", the China Railway 11 Bureau uses items. Networking technology has developed a "cloud vision world" system for tower crane safety management monitoring, which can realize the visual management of tower cranes, and put "Thousand Miles Eyes" for the tower crane.

Yao Xiangyang told reporters that after this system, the tower crane driver can master the picture and data displayed by the cabinet screen and the tie of the tower crane and the locking of the hanging objects to avoid "blind hanging" and ultra -limited load operations. At the same time, the project managers can check the use of tower cranes and cabin in real time through the computer or mobile terminal to achieve remote supervision.

High -tech equipment helps the railway "penetrate mountains and mountains"

In addition to the OK, the construction of a new Fuxia Railway will also face the test of crossing the mountains.

Taking the Bifeng Temple Tunnel in Fuqing City and Putian City as an example, the total length of the tunnel is 8.4 kilometers. It is the most difficult control project in the construction of the Fuxia Railway. During the construction process, the tunnel needs to cross 8 broken layers of crushing bands, 8 -festival -intensive bands, and 480 meters of strong rich water areas. There are often phenomena such as water and mud, which is difficult to build.

Lu Qingzhao, the person in charge of a company in the Sino -Railway 16th Bureau Group, introduced that in the face of complex geological conditions, the construction staff comprehensively adopted advanced scientific detection methods such as geological radar, advanced horizontal drilling, and three -dimensional laser scanning. Mechanized equipment such as robotics and multi -functional lining vehicles. Under the cooperation of the participating units, the tunnel has been successfully connected on May 10 last year.

Intelligent railway construction accelerate the development of coastal urban agglomerations

Under the blessing of digital technologies such as big data and cloud computing, intelligence has become a major feature of the construction of a new Fuxia Railway project. The reporter had previously seen at the Smart Control Information Center of the Fuxia Railway 5 standard project of the China Railway Shanghai Engineering Bureau that dozens of screens have been continuously converted to the screen. The construction data of various bridges are updated in real time. Wait at a glance.

The relevant person in charge of the Southeast Coastal Railway Fujian Co., Ltd. introduced that the entire bridge -tunnel ratio of the Fuxia Railway was as high as 84.3%, and there were technical problems such as difficulty in communicating with the communication difficulties, vehicle positioning and vehicle speed monitoring difficulties.To this end, the construction and construction unit uses the current domestic leading comprehensive commanding scheduling system, and integrates the functions of wireless network transmission, positioning and navigation into the scheduling system, to achieve intelligent, informatized, and visual management of scheduling command.The new Fuxia Railway, which is 277.42 kilometers in length, is an important part of the coastal channels in my country's "Eight vertical and Eight Heng" high -speed railway network. Construction started in September 2017 and is expected to open operations in 2023.After the railway is completed and opened to traffic, Fuzhou and Xiamen will form a "one -hour life circle". Xiamen, Quanzhou, and Zhangzhou will form a "half -hour traffic circle", which is of great significance to promote the rapid development of the southeast coastal urban agglomeration.
