At 0:55 on May 9, 2022, 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 Guangzhou-Shantou high-speed railway key project crossed the Beijing-Kowloon Railway Super Bridge continuously. The beam turned successfully and opened up the throat of the project. In the next step, the Guangzhou-Shantou high-speed railway will be fully transferred to the construction stage of ballastless track and track laying.
At 23:50 on May 8, 2022, the construction site of the Guangzhou-Shantou High-speed Railway Cross-Beijing-Kowloon Railway Super Bridge was brightly lit. The operation of the double-width swivel beam on the pier top of the 33.4-meter-high cross-Beijing-Kowloon Railway Super Bridge was officially started, and the beam body slowly rotated in a clockwise direction. , the large screen of the on-site command center constantly refreshes and displays the real-time rotation data of each part. The staff divides the labor and cooperates to monitor and adjust the rotation speed in real time in an orderly manner according to the scale number arranged on the turntable, the data transmitted by the speed sensor and the camera. At 0:55 on May 9, the continuous beam of the Guangzhou-Shantou High-speed Railway Crossing the Beijing-Kowloon Railway Super Bridge completed a double-width synchronous pier top rotation of 77 degrees, and the two beams were accurately connected at an altitude of 33.4 meters, successfully "flying" Beijing The top of the Nine Railways successfully "held hands".
The Guangzhou-Shantou high-speed railway is about 206 kilometers long and has a design speed of 350 kilometers per hour. It is a regional connection line of high-speed railways planned and constructed in China's "Thirteenth Five-Year Plan" and an important part of the high-speed railway backbone network of "Greater Bay Area on Tracks". 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 shortened from the current 2 hours to about 40 minutes at the fastest.Editor/Ma Xue
