By the banks of the Yangtze River, amid the mountain scenery, a new wharf is quietly rising. The Qichun project of PowerChina Port and Waterway Engineering Co., Ltd. is pressing hard toward the "12·30" schedule milestone, unfolding a beautiful picture of racing against time.

Adding luster to a new vision of the "Yangtze River Economic Belt"

Qichun County is a resource-rich county in Hubei Province. Relying on its abundant mineral resources, easy-to-mine characteristics and high-quality products, it has steadily developed into a resource-export-oriented city, undertaking the important task of supplying bulk bulk cargo such as non-metallic ores and mine construction materials to the middle and lower reaches of the Yangtze River, and is an indispensable material supply base in the region.

The construction of the green building materials wharf in the Maoshan Port Area of Qichun Port has added new vitality to this resource-export-oriented city's "regional coordination and integrated development." The project construction has increased the region's commercial circulation channels, enabling Qichun's mineral resources to be transported more conveniently to all parts of the country and even overseas markets, significantly reducing logistics costs and improving transport efficiency. The wharf construction embodies a clear stance of "ecological priority and green development," greatly improving Qichun's investment environment, attracting more enterprises and investors to visit and invest, accelerating the development of Qichun's mining, logistics, manufacturing and other industries, and enhancing the region's comprehensive competitiveness. In promoting the rational layout of riverside cities and productive forces, the wharf construction has strengthened Qichun's economic ties and cooperation with the middle and lower reaches of the Yangtze River and even broader regions, promoted the coordinated development of riverside cities, and injected new momentum into the overall improvement of the regional economy.

Fearlessly venturing to mountains and seas

Looking at the construction site, a high-efficiency pile-driving vessel is busy carrying out pile foundation work; flat barges shuttle between the site and the material storage area, and three floating cranes stand tall, precisely lifting equipment and materials. Barges, anchor boats, cargo ships, one 50-ton truck crane and two 25-ton trucks... Amid the roar of machinery is a busy Qichun and a striving Qichun!

Since the project started, the tight schedule has been a huge stone weighing on the mind of every participant. Faced with the urgent timetable and complex construction difficulties, working overtime has become routine. The project management team carefully planned and "deployed its forces," implementing an efficient shift system. Through rational allocation of human resources, construction personnel rotate in an orderly manner, which not only ensures the continuous and efficient operation of the construction site but also ensures that on-site workers get rest. Sufficient preparation and timely supply of materials are the prerequisites for the project to proceed continuously and efficiently. The project department planned ahead and established close cooperative relationships with a number of suppliers, ensuring the stable supply of key materials such as steel, concrete and various embedded parts. At the same time, it optimized inventory management, reduced material waste, and continuously improved material use efficiency, providing a solid material foundation for the rapid advancement of the project. To improve construction efficiency, the project department also actively coordinated and introduced advanced and efficient construction equipment, providing strong support for the rapid advancement of the project.

By intervening in communication in advance and implementing design planning through multiple measures, the project team pooled the strength of many people and demonstrated extremely high adaptability and flexibility, making every step of the Qichun project solid and powerful.

The "wave" of technological innovation surges

Those who dare to innovate advance; those who are good at creating win. The Qichun project proactively rides the "wind of innovation," promoting project construction with new thinking, new breakthroughs and new leaps, greatly improving construction efficiency and project quality.

In order to further tap construction potential, the project team deeply analyzed and optimized the construction process of hollow slabs and promoted the application of post-tensioned prestressed hollow slab construction technology. By accurately identifying key processes, a set of standardized construction processes tailored to the actual project was customized, greatly reducing unnecessary losses and winning valuable time and resources for the construction project. In the core links of hollow slab construction, a comprehensive and detailed assessment was conducted on key materials such as concrete, admixtures, grouting materials, steel bars and anchors. On the basis of ensuring that all materials met quality requirements, careful screening and scientific proportioning effectively reduced material costs, successfully achieving the dual goals of cost control and efficiency improvement, and laying a solid foundation for the smooth advancement of the project.

Through in-depth analysis of the project's characteristics, difficulties and key construction points, combined with sufficient input of manpower and material resources and the selection of high-quality materials, the project department successfully formulated and implemented a set of efficient and feasible installation construction processes and methods—efficient construction technology for complex berthing systems. This technology optimized the construction process and improved construction efficiency, while effectively reducing costs and shortening the construction period, accumulating valuable experience for similar construction and cultivating a group of professional port construction technicians.

Plan for the long term, adopt lasting strategies, and build a foundation for enduring stability. The green building materials wharf project in the Maoshan Port Area of Qichun Port keeps its eyes on the milestones and strives to sprint forward. As of recently, the civil construction completion rate of the wharf approach bridge is as high as 95%; for the wharf berths, the pile foundation and superstructure adopt a full-process flow operation mode, and the construction team is going all out to meet the civil construction handover milestone for Berth 3; in terms of transfer station construction, the pier and abutment foundation construction has been successfully completed, and the project has now shifted to preparations for the superstructure construction of the transfer station. The project team is going all out to accumulate inch-by-inch achievements and deliver drop-by-drop results for the high-quality development of the Yangtze River Economic Belt, jointly writing a new chapter in the development of the Yangtze River Economic Belt.
