On February 28, full-scale construction resumed on the Guangxi section of China's newly built Hezhou-Zhanjiang High-Speed Railway (hereinafter referred to as the Hezhan HSR). Machinery roared at 25 work sites along the line, with over 700 builders working hard to advance the project.
On the morning of the 28th, at the Nankang East Main Canal Grand Bridge of the Hezhan HSR in Hepu County, Guangxi, two rotary drilling rigs were carrying out pile foundation construction. Construction personnel methodically prepared for tasks such as site leveling and support installation for cast-in-place continuous girders. Technical personnel, adhering to safety-through management requirements, carefully inspected each work step.
Zhao Changwei, the work area manager of the China Railway 16th Bureau Group's Hezhan HSR project department responsible for the bridge construction, introduced that the Nankang East Main Canal Grand Bridge is approximately 1.27 kilometers long and is one of the key projects to open up the girder erection channel for the Guangxi section of the Hezhan HSR. At the beginning of the new year, they added two work teams to launch full-scale construction on the bridge. Currently, the bridge pile foundation construction is largely complete. The next step involves advancing bridge construction according to the plan of completing two pile caps per day and one pier body casting every three days, ensuring the girder erection channel is opened on schedule.
At the Beihai Beam Prefabrication Yard for the Hezhan HSR, construction is also in full swing. This yard is responsible for the prefabrication and erection of 688 simply-supported box girders. All stages, including steel reinforcement production, formwork fabrication, and tensioning tests, are proceeding in an orderly manner, striving to complete the erection of the first box girder for the entire line before July this year.
The main line of the Hezhan HSR is approximately 139 kilometers long, with a design speed of 350 km/h. It is an important component of the Baotou (Yinchuan)-Haikou Corridor and the Coastal Corridor within China's "Eight Vertical and Eight Horizontal" high-speed railway network. As of now, 6,274 bridge pile foundations have been completed on the Guangxi section, 206 bridge piers have been built, and 323,100 cubic meters of subgrade earthwork have been finished. The project is expected to be completed and open to traffic in 2028. Upon completion, it will be of great significance for expanding the coastal railway transport capacity of Guangdong and Guangxi, optimizing and improving the regional railway network layout, facilitating travel for residents along the line, promoting the construction of the Beibu Gulf urban agglomeration, and driving high-quality economic and social development in the areas it traverses.
