China News Service, Huizhou, May 9 (Guo Jun, Li Lei, Lin Qunhai) At 0:55 on May 9, under the high-power traction of 2 DLD1200 hydraulic continuous jacks and 2 ZLDB hydraulic pump stations, after 65 minutes of continuous clockwise rotation, The key project of the Guangzhou (Zhou) Shan (Wei) high-speed railway has successfully turned the continuous beam of the super bridge across the Beijing-Kowloon Railway, which has opened up the "throat" of the construction of the project.

The Guangzhou-Shantou high-speed railway will be fully transferred to the construction stage of ballastless track and track laying.

　　At 23:50 on the 8th, the construction site of the Guangzhou-Shantou high-speed railway crossing the Beijing-Kowloon railway bridge was brightly lit, and hundreds of builders were ready to go.

With the command of the on-site commander, the operation of the double-width swivel beam across the pier top of the 33.4-meter-high Beijing-Kowloon Railway Super Bridge was officially launched. Rotation data, the staff divides the labor and cooperates, according to the scale number arranged on the turntable, the data transmitted by the speed sensor and the camera, the rotation speed is monitored and adjusted in real time in an orderly manner.

At 0:55 on the 9th, the continuous beam of the Guangzhou-Shantou high-speed railway crossing the Beijing-Kowloon Railway Super Bridge completed the double-width synchronous pier top rotation of 77 degrees, and the two beams were accurately connected and connected at an altitude of 33.4 meters, successfully "flying" the Beijing-Kowloon Railway. The top "holds hands" smoothly.

　　It is understood that the Guangzhou-Shantou High-speed Railway Cross-Beijing-Kowloon Railway Bridge is located in Huizhou City, Guangdong Province, with a total length of 698.54 meters.

Among them, the swivel continuous beam has a total length of 157.858 meters, forming an included angle of 77° with the Beijing-Kowloon Railway. At the same time, it spans the Beijing-Kowloon Railway, Changshen Expressway, and Huixin Avenue, a municipal road in Huizhou City, which is in operation. The location is prominent and the technology is complex.

　　"The super bridge across the Beijing-Kowloon Railway is the only swivel construction super bridge on the whole line. The successful swivel and closing is a key part of the operation of the Guangzhou-Shantou high-speed railway." The relevant person in charge of the Guangzhou Engineering Construction Headquarters of Guangzhou Railway Group told reporters that the bridge crosses The Beijing-Kowloon Railway and Changshen Expressway are one of the busiest railways and expressways in China. At the same time, the bridge is also located in Honghua Lake Scenic Area, a nature reserve and a national 4A-level tourist scenic spot. Continuous beam construction, construction across existing railway and highway operating lines, etc., the construction difficulty and environmental protection requirements are the key control links in the construction of the entire Guangzhou-Shantou high-speed rail line.

　　It is reported that the Guangzhou-Shantou high-speed railway officially started construction on March 28, 2019, with a total length of about 206 kilometers and a design speed of 350 kilometers per hour. "An important part of the high-speed rail backbone network.

After the completion and opening to traffic, it will connect Beijing-Guangzhou, Beijing-Hong Kong high-speed railway and coastal railway, and further strengthen the railway network in the Greater Bay Area.

By then, the train running time from Guangzhou to Shanwei will be compressed from the current 2 hours to about 40 minutes at the fastest.
