Fuzhou-Xiamen high-speed railway is expected to open next year, and Fuzhou and Xiamen will realize the 1 hour living circle. With the completion of Fuzhou-Xiamen high-speed railway, the space-time distance between Fuzhou, Xiamen, Quanzhou and Zhangzhou will be shortened. Fuzhou-Xiamen high-speed railway is expected to open next year, and Fuzhou and Xiamen will realize the 1 hour living circle.

Fuzhou-Xiamen high-speed railway is expected to open next year, and Fuzhou and Xiamen will realize the 1 hour living circle. 1 Before, the last continuous beam of the newly-built fuzhou-xiamen railway, which was built by Beijing Railway Construction Company of China Railway Sixth Bureau, was successfully closed. The completion of this key node marks the completion of the main project of the Fuzhou-Xiamen high-speed railway bridge, and the construction has changed from offline bridging to online track laying, which has taken a solid step for the smooth opening of China's first cross-sea high-speed railway.

The construction contents of Fuxia Project Department of Beijing Railway Construction Company of China Railway Sixth Bureau include Jimei, Tianzhu Mountain, East Ford Bridge and two sections of subgrade, with a total length of 16.3 km, all located in Xiamen. All participants are very concerned about key tasks such as land acquisition, demolition, safety management and quality control. Concentrated efforts, burning the midnight oil, crossed one danger after another, and ensured the smooth closure of all 18 continuous beams.

At the site of continuous beam closure, Xi Yalin, Minister of Project Safety, introduced that this bid section * * * includes three extra-large bridges, 18 continuous beam, accounting for 96% of the total number of bridges. The continuous beam of Helong across Xiamen National Road G3 19 is the last piece of the bid. It has to cross six lanes with dense traffic, and the clearance distance at the bottom of the beam is only 15 meters. The tight construction period, complex external construction environment and high safety risk level are another major test for the construction technology and management level of the project department.

"The * * * in the section includes 18 continuous connection, and every closure construction is like walking a wire rope, and there is no room for carelessness." Ray, the safety director, described it as follows: "Among them, highway crossing 14, expressway crossing 2, stream crossing 1, and reservoir crossing 1. At the same time, it also involves the construction of adjacent existing lines, oil pipelines, deep foundation pits and high piers, which are safety risk points everywhere. "

Due to the relocation of oil and gas pipelines, continuous beams started late. In order to effectively speed up the construction progress and ensure the construction period of nodes, the project department made overall arrangements, actively communicated with the design unit and optimized the drawings. By reducing the number of continuous beam segments and adjusting the prestressed tensioning form, the continuous beam construction period is effectively shortened and the delayed construction period is saved.

Faced with the double challenges of tight construction period and severe safety situation, the project department carried out in-depth risk control and hidden danger investigation and rectification, strengthened safety technical exchange training, implemented hidden danger investigation and classification management, and strictly changed the acceptance order of key processes, thus achieving the safety production goal of 18 continuous beam "0 accident" closure.

The three extra-large bridges built by the project department are all located in Xiamen. The geological conditions along the line are complex, involving many unfavorable factors such as oil and gas pipeline relocation and cross construction. In addition, the local high temperature and heat in summer and long rain in rainy season make the construction of all 4,392 pile foundations very difficult. "If the geological conditions are not good, then we will nibble a little and walk step by step; If there is no construction site, then we will find a sewing needle to sew the needle. " Liu Hui, Party branch secretary of the project, said.

As a national key project of "One Belt, One Road" construction, the newly-built fuzhou-xiamen railway is an important passage for the southeast coastal high-speed railway in the "eight verticals and eight horizontals" planning of China Railway, and it is also the first cross-sea high-speed railway in China. After the Fuzhou-Xiamen high-speed railway is completed and opened to traffic, Fuzhou and Xiamen will realize the "one-hour life circle", which is of great significance to promote the rise of Fuzhou and Xiamen-Zhang Quan as the main engines of Fujian's development and accelerate economic and social development.

At the same time, as an important extension of Beijing-Fuzhou high-speed railway, the completion of Fuzhou-Xiamen high-speed railway will enable six cities in Fujian to realize "high-speed railway entering Beijing", which is of great significance to the construction and development of coastal high-speed passenger corridors.

Fuzhou-Xiamen high-speed railway is expected to open next year, and Fuzhou and Xiamen will realize the 1 hour living circle. According to CCTV Financial Channel, the main bridge of Fuzhou-Xiamen high-speed railway, the first cross-sea high-speed railway in China, has been completed.

It is reported that the Fuzhou-Xiamen high-speed rail line starts from Fuzhou in the north and ends in Xiamen and Zhangzhou in the south. There are 8 stations in Fuzhou South, Fuqing West, Putian, Quangang, Quanzhou East, Quanzhou South, Xiamen North and Zhangzhou, with a total length of 277.42 kilometers and a design speed of 350 kilometers per hour. It is expected to run in the second half of next year.

In order to ensure safe, high-quality and efficient track-laying construction, the construction unit adopts the advanced construction technology and mechanical equipment of the country, and integrates wireless network transmission, positioning navigation and other technologies into the dispatching system to realize intelligent, informational and visual management of dispatching command.

In addition, during the construction of Fuzhou-Xiamen high-speed rail Meizhou Bay cross-sea bridge, the 1,000-ton all-in-one crane "Kunlun" independently developed by China made its debut, which filled many gaps in the field of high-speed railway construction in China and achieved a new breakthrough in high-speed railway construction technology.

With the opening of Fuzhou-Xiamen high-speed railway, the time and space distance between Fuzhou, Xiamen, Quanzhou and Zhangzhou will be shortened, and Xiamen-Rong Ning will form a 1 hour traffic circle and Xiamen-Zhang Quan will form a half-hour traffic circle, which will promote the rapid development of Haixi urban agglomeration.

As an important basic and pilot project to speed up the construction of the "Belt and Road" Maritime Silk Road and Fujian Pilot Free Trade Zone, Fuzhou and Xiamen will form a "one-hour life circle" after the completion and opening of the Fuzhou-Xiamen high-speed railway, which is of great significance to promoting the rapid rise of Fuzhou, Xiamen-Zhang Quan metropolitan area and promoting economic and social development.
