Investment in transport infrastructure, due to its large scale and strong multiplier effect, serves as a crucial engine for driving economic growth. Since the beginning of this year, the province has planned and initiated a large number of transportation projects, enhancing construction quality and efficiency through refined and intelligent management.

In the first half of the year, the province completed an investment of 65.09 billion yuan in transport infrastructure construction, achieving 52.9% of the annual plan and surpassing the halfway point in both time and task completion. Currently, the second phase of the Quzhou-Huanghua Expressway project in Cangzhou City is under intensive construction. The Nan Canal Bridge, part of the project's second section, is a key control point for the entire undertaking.

At the construction site, the sounds of machinery are constant as workers systematically carry out operations such as bent cap casting and the installation of temporary support piers. Wang Liyong, Project Manager for the Second Section of the Quzhou-Huanghua Expressway Phase II Project, explained the unique approach: "Because this bridge is located over the Beijing-Hangzhou Grand Canal, a nationally protected key cultural heritage site, we are employing a single-span, sunken tied-arch bridge design. This method actively protects the cultural relics and the surrounding ecological environment."

Currently, 80% of the substructure work for the main bridge is complete, with the main structure of the bridge scheduled for completion by the end of the year. As a key provincial construction project, the Quzhou-Huanghua Expressway Phase II spans 84.239 kilometers with a total investment of 13.4 billion yuan, serving as a vital corridor connecting Huanghua Port eastward and westward.

To ensure the project progresses to a high standard, a comprehensive quality supervision responsibility system has been implemented. Intelligent monitoring equipment and smart construction systems have been introduced to collect key construction parameters in real-time, establishing a closed-loop system of collection, warning, verification, and rectification, effectively enhancing both project quality and efficiency.

Zhang Shusen, Deputy General Manager of the Quzhou-Huanghua Expressway Phase II Project Company, highlighted a specific application: "Take the concealed work of soft foundation treatment, for example. We activated an intelligent monitoring system for cement mixing piles to track core parameters like cement usage, drilling depth, and mixing speed in real-time. The system has a built-in dynamic warning function; if construction parameters deviate from the standard values, the equipment immediately alerts, and on-site managers intervene promptly for correction, completing the closed-loop rectification."

It is understood that upon completion, the Quzhou-Huanghua Expressway Phase II will establish the most convenient sea access channel from the Xiongan New Area to Huanghua Port. It will interconnect with several major expressways, including the Beijing-Hong Kong-Macau, Da-Guang, Beijing-Taipei, Beijing-Shanghai, Rongcheng-Wuhai, and Qinhuangdao-Binzhou routes, effectively alleviating traffic pressure on existing corridors like the Huangshi and Cangyu expressways.

While the expressway network becomes increasingly dense, effective investment in the province's ports is also expanding. In Tangshan, the construction of Berths 51 and 52 for bulk cargo at the Jingtang Port Area of Tangshan Port, with a total investment of 5.899 billion yuan, is progressing smoothly. Relevant officials noted that as the project involves berths for iron ore and other minerals with substantial cargo tonnage, the construction process places high demands on foundation bearing capacity.

Zhang Bo, Head of the Second Engineering Management Department at the Project Center of Hebei Port Group, detailed the technical approach: "For the first time, PCC large-diameter pipe piles were used to reinforce the track beam area, effectively preventing secondary settlement in the later stages. Foundation treatment was combined with long-term preloading of the stockpile. The recent foundation treatment achieved a bearing capacity of 25 tons, which is expected to reach 35 tons in the long term."

It is reported that China's imported iron ore for foreign trade primarily comes from countries like Australia and Brazil, with the main transport vessels being 200,000-ton class and above. Berths 51 and 52 at Jingtang Port Area are designed as two 300,000-ton class bulk cargo berths with corresponding supporting facilities, boasting a designed annual throughput capacity of 25.6 million tons. Upon completion, the project will enhance the port's capability to handle large vessels, accommodate the main iron ore transport ship types, and support the development of the steel industry in the hinterland.

Since the beginning of the year, the province's transportation department has established a coordination and promotion mechanism for project preliminary work, launched a series of project攻坚 actions, and集中 resolved a number of难点堵点 problems. It has secured 10.941 billion yuan in central government funds, providing strong support for the accelerated advancement of 129 key transportation projects implemented this year.

In the first half of the year, the province completed an investment of 65.09 billion yuan in transport infrastructure construction, achieving 52.9% of the annual plan and representing a year-on-year increase of 1.2%. Wang Yueqiang, Deputy Director of the Comprehensive Planning Division of the Provincial Department of Transport, outlined the next steps: "Moving forward, we will anchor ourselves to the annual target of 123 billion yuan in construction investment. We will carry out three攻坚 actions focused on 'promoting project starts, ensuring ongoing construction, and抓储备 of future projects.' We will ensure the timely completion of a batch of key projects, including the second phase of the Beijing-Xiongan Expressway, the Jiumenkou复线, and the Hengshui-Dezhou Expressway expansion, shouldering the transportation sector's responsibility for stabilizing investment and promoting development across the province."
