At 8 o'clock in the morning of May 13, with the pumping of the last concrete, the G32 main tower of the main bridge of the west branch of the Longxing Bridge across the Ganjiang River completed the concrete pouring of the middle beam, laying the foundation for the smooth capping of the subsequent main tower, marking the phased victory of the construction of the main tower of the bridge.
It is understood that the pouring of the middle beam is a high-altitude curved beam, 80 meters away from the top surface of the trestle, 21.7 meters long, the beam section is designed as a single box and single chamber section, the section is 3 meters high, 5.8 meters wide, the linear adjustment is more cumbersome, the accuracy requirements are higher, the quality control is more difficult, and the pouring is completed in two times.
At present, 43% of the total design of the Longxing Bridge has been completed, and it will set a number of world records after completion. The Changjiu high-speed railway has completed 60% of the total design, and it is expected that all offline projects will be completed in the first half of 2025, which is of great significance for our province to build an integrated comprehensive transportation system in Changjiu, further integrate into the Guangdong-Hong Kong-Macao Greater Bay Area, help the implementation of the development strategy of the Yangtze River Economic Belt, and promote high-quality economic and social development along the line.
