Huo Jiangfeng, chief engineer of the fourth bid section project in front of the Kangyu section of the Xiyu high-speed railway, introduced that the No. 2 six-line bridge at Fanhui Station has a total length of 1207.3 meters and a design pile foundation of 537, which is a high-quality demonstration project focused on building in the bid section. As the first unit to be poured during the sectional construction of the large-span continuous beam bridge, block 0 is located at the top of the main pier, which is the first block extending from the pier stud to both sides, and is also the key node of the continuous beam construction.
Block 0 pouring operation.
The first continuous beam No. 0 block poured this time is a four-line continuous beam, which can accommodate four railway lines at the same time to improve the railway transportation capacity, with a total pouring concrete volume of 580.03 cubic meters, which is poured and formed at one time. "This is a major node construction result of the bridge construction in the four bid sections in front of the station, laying the foundation for the construction of 9 continuous beams in the bid section in the future."

Fan Hui Station is the junction point of the main line and the connecting line of the West Chongqing High-speed Railway, limited by the terrain, the two ends of the station to the departure line are respectively through the Fan Hui Station No. 1 six-line bridge, Fan Xu Station No. 2 six-line bridge across the river, the turnout will be built on the two bridges. These two extra-large bridges are the first batch of construction points in front of the 4 bids in front of the Kangyu section of the Xiyu high-speed railway.
There are many tunnels, many bridges and many times to cross the river, which are the significant characteristics of the construction of the West-Chongqing high-speed railway in Xuanhan County, which has 24 tunnels totaling 115.55 kilometers and 28 bridges totaling 9.24 kilometers in about 127 kilometers of Xuanhan County, with a bridge-tunnel ratio of 98.41%.
