China News Service, Hangzhou, October 5 (Xi Jinyan, Mei Qing, Xu Wang) In the golden autumn of October, the enthusiasm for transportation construction in Zhejiang remains unabated. During the National Day holiday, many major projects of Zhejiang Communications Group advanced as planned, and builders seized the favorable opportunity for autumn construction. From cross-sea projects on the coast of the East China Sea to highway and railway projects in the mountainous areas of southwestern Zhejiang, on-site machines roar and welding flowers splash, and the provincial road network speeds up.
Cross-sea and cross-domain projects are accelerated, and the construction of the East Zhejiang Corridor is accelerated
Facing the East China Sea, a number of cross-sea and cross-domain transportation projects are under construction. As a strategic expressway corridor between Zhoushan and the mainland, the double-track construction site of the Ningbo-Zhou Expressway is busy. More than 1,800 builders of the first phase of the project are working on the construction site, carrying out tunnel excavation, beam and slab erection, cantilever pouring and other operations. The project has detailed management and control of construction nodes, coordinated the deployment of human and mechanical resources, and strictly controlled safety and quality. As of now, the overall progress has reached 68.04%; the second phase of the project spans Ningbo and Zhoushan, and more than 1,000 builders are working hard at 13 main work points to accelerate the excavation of the shield starting shafts on both sides to ensure that the main structure of the working shafts is completed by the end of the year, laying a solid foundation for the subsequent launch of the super-large diameter shield.
While the construction of the cross-sea channel is accelerating, the construction of the Ningbo Phase III Hangzhou-Ningbo Double Line, an important component of the National Highway Hangzhou-Ningbo Double Line and the core collection and distribution channel of Ningbo Zhoushan Port, is also continuing to advance. At the construction site of the Haiyu Viaduct, the builders carried out steel bar tying and electric welding operations in an orderly manner, promoted the construction of cast-in-place box girders on mobile formwork, and pushed forward the left side of the Haiyu Viaduct at full speed. During the National Day, more than 2,700 builders were deployed at 42 work sites to sprint towards the main line completion target by the end of the year to ensure that the project will be completed as scheduled in 2027. Up to now, the project has completed a total investment of 17.036 billion yuan, and the overall image progress has reached 72%. After completion, the project will significantly improve Ningbo's expressway network and improve the efficiency of Ningbo-Zhoushan Port's collection and distribution. It will have important strategic significance for Zhejiang to build a world-class port and deeply integrate into the integrated development of the Yangtze River Delta.
In addition, on a number of cross-ocean railway projects such as the Sujia-Ningbo High-speed Railway and the Toumen Port Branch Line Phase II project, builders gave up their vacations and stayed on the front line, seizing the golden construction period in autumn and making every effort to promote project construction.
Extension of mountain passages, major projects advanced in an orderly manner
In the mountainous areas of western Zhejiang and southwestern Zhejiang, the construction of major transportation projects such as the Hangchun-kai Expressway, Yilong-Qing Expressway, and Yongjin Qushang has accelerated.
During the festival, the Hangchun-Kaifeng Expressway, which is about 245 kilometers long, maintained its efforts to tackle difficulties. On the 184-kilometer construction line of the Hangzhou section, more than 9,600 builders are on duty during the holidays. On the bank of Qiandao Lake, the construction of the left mouth hub of the project's control project is continuing. Work such as the erection of steel trestles and drilling platforms are being simultaneously advanced on site. The four working areas are progressing in parallel to seize the construction period for the subsequent continuous drilling of pile foundations in the water. From the construction of large-scale temporary facilities to pile foundation construction, tunnel excavation, and roadbed filling and excavation, builders across the entire project are advancing construction at key work points. After the project is completed, it will end the history of 11 towns and villages along the line being blocked from expressways and provide transportation support for high-quality development along the line.
More than 3,000 builders are on site in the Quzhou section. 66 work teams are distributed on 99 working surfaces. 42 bridges and 16 tunnels are under construction simultaneously. The inter-provincial highway continues to extend to the border between Jiangxi and Zhejiang.
While the mountainous highway project is accelerating, the railway project is also advancing in an orderly manner as planned. As a key transportation artery connecting Quzhou and Lishui in southwestern Zhejiang, the Qu-Li Railway seizes the golden construction period in autumn to accelerate the reconstruction of Lishui Station and the construction of control projects such as the Yangshan Tunnel, Yejiadian Tunnel, and Qujiang Super Bridge. As of the end of September, the completion rate of the roadbed, bridges, culverts, and tunnels in the first phase of the project exceeded 98%, and the annual investment completion progress of the first and second phases exceeded 75%.
Smart construction empowers construction to improve quality and efficiency of project construction
Technological empowerment can improve the quality and growth rate of engineering construction. At the construction site of the Quzhou section of the Yongjin-Qushang Expressway, nearly 6,000 builders are working on the front line. Drone inspections, rust removal robots, intelligent tensioning equipment, AI inspection robot dogs, etc. have been put into use one after another, building a full-process intelligent construction system. The concept of "machine substitution, quality improvement and efficiency improvement" is being transformed into actual results of project construction. As a landmark project for the west extension of the Yi-Ningbo-Zhou Open Channel, the project has completed a total investment of 8.457 billion yuan, using digital means to ensure high-quality construction of the project.
Deep in the mountains of southwestern Zhejiang, the construction of the Lishui section of the Yilong-Qing Expressway is progressing steadily. In the Niutoushan extra-long tunnel, a complete set of intelligent equipment such as an intelligent three-arm rock drilling rig and an intelligent arch and anchor integrated machine work together to replace the traditional manual operation mode; in the intelligent monitoring center, the tunnel intelligent construction system collects on-site data in real time and relies on functional modules to output construction decisions. This mode not only shortens the operation time of a single cycle, but also reduces the safety risks of tunnel construction, making engineering construction under complex geological conditions safer and more efficient. During the National Day, more than 5,000 construction workers took root in the mountains and paved the way for the revitalization of mountainous areas with their sweat.
Roads and bridges continue to extend deep into the mountains and seas, and bridge towers and station buildings rise from the ground. During this National Day holiday, countless transportation builders stayed on the construction front line. Their busy figures have become a moving scenery in the festival, and also constitute a solid force for the steady progress of the transportation integration of the Yangtze River Delta.
