On July 29, a reporter from Xinhua Daily · Jiaohuidian learned from the Jiangsu Provincial Railway Office thatin the first half of the year, the province's railway construction completed investment of over 39 billion yuan. At present, the enthusiasm at railway construction sites across the province shows no sign of abating, as steel dragons accelerate their extension, adding new mileage to "Jiangsu on Track."

Stepping into the construction site of Taizhou South Station, waves of heat mixed with the roar of machinery hit you in the face. Builders from China Railway 12th Bureau Group are seizing the cooler morning and evening hours, avoiding the midday sun, and working in an orderly staggered rhythm of "grasping both ends and resting in the middle."

As the core controlling hub of the entire line, the Taizhou South Station has complex construction organization, dense cross-operation, and high quality standards. While firmly and meticulously implementing heatstroke prevention and cooling measures, the project department continues to optimize construction plans and increase investment in resource elements to ensure that all target milestones remain orderly and controllable.Zheng Jinpu, chief engineer of the project department, introduced that at present, the mainline bridge works of the Shanghai-Nanjing-Hefei High-Speed Railway (along the Yangtze River) have all been completed, with only the last 1.8 kilometers of ballastless track remaining, and the team is going all out to sprint toward the mid-September track-laying milestone; the substructure of the synchronously implemented works of the Yancheng-Yixing High-Speed Railway has all been completed, and the mainline box girders were fully erected in April this year. The construction team is now concentrating its efforts on key processes such as cast-in-place girders, continuous girders, and box girder erection, and station construction has fully entered the sprint stage.

Turning to Changshu, at the construction site of the T-shaped rigid frame bridge of the Suyu Grand Bridge in Section 6 of the Nantong-Suzhou-Jiaxing-Ningbo High-Speed Railway station works of China Railway Guangzhou Engineering Group, workers are nervously and orderly carrying out concrete pouring. Feng Jie, head of the project department, introduced that the T-shaped rigid frame bridge has a total length of 101.41 meters and is the last cantilever-cast continuous girder in the Changshu section of the Nantong-Suzhou-Jiaxing-Ningbo High-Speed Railway. The completion of the pouring marks the full closure of continuous girder construction in the Changshu section, thoroughly opening up the subsequent girder erection channel and creating the necessary conditions for ballastless track laying and bridge deck system construction. As of now, the pile foundations, pile caps, pier shafts, and continuous girders within the section have all been completed, more than 60 percent of box girder prefabrication has been completed, and more than half have been erected. All box girder erection tasks are expected to be completed before the end of the year.

At the construction site of the Taicang pilot section of the Shanghai-Suzhou-Wuxi-Changzhou Intercity Railway, multiple tasks including station structure construction, tunnel shield construction, and railway bridge construction are advancing side by side, with above-ground and underground work progressing together. "At present, 59 percent of the project's subgrade works, 45 percent of the bridge works, and 52 percent of the station building works have been completed. Among them, the double-line excavation of the shield tunnel from Taicang Station to Baiyundu Road Station, a controlling project, has reached 5 kilometers, accounting for 52 percent of the tunnel's total length."Li Xiaofeng, general manager of the Construction Company of Jiangsu Railway Group, told reporters thatat present, the project department is focusing on advancing the construction of the shield launching shaft for the tunnel section from Baiyundu Road Station to Shibagang Road Station and the systematic commissioning of shield equipment, striving to achieve shield launching and excavation within the year.

Over the Chuhe River, sparks from welding fly at the construction site of Section 5 of the Nanjing-Huai'an Intercity Railway station works of China Railway Shanghai Engineering Group. The steel-concrete composite girder over the Chuhe River has a total length of 393 meters, with a large span, high technical content, and great construction difficulty, making it a key controlling project of the project. "As of now, all pile foundations across the entire section have been completed, pile caps and pier shafts are nearly 100 percent complete, continuous girders and turnout continuous girders have all been closed, and box girder erection progress has exceeded 60 percent. The girder erection task is expected to be completed before the end of the year."Wang Haifeng, head of the project department, said.

Looking further south to the Yancheng-Yixing High-Speed Railway, at the construction site of the Qishan Village Grand Bridge in Section 1 of the Yancheng-Yixing High-Speed Railway station works of China Railway 24th Bureau Group, workers' hooks rise and fall as rebar tying proceeds with flowing smoothness. Zhang Lei, the project leader, introduced that the bridge has a total length of nearly 4 kilometers and requires driving 1,003 bored piles and pouring 117 pile caps and 113 pier shafts. At present, pile foundation construction has cumulatively completed nearly 70 percent, and pile caps and pier shafts are also steadily advancing. According to the established construction plan, the first continuous girder closure task is expected to be completed before the end of the year, while construction of the bridge superstructure is being advanced in a coordinated manner.

The head of the Construction Management Department of Jiangsu Railway Group introduced that since the beginning of this year, the group has continued to make good use of major construction project coordination mechanisms such as the four-party railway-provincial meeting, strengthened cooperation with railway-side units and the provincial railway industry competent authorities, and made every effort to ensure the smooth and orderly progress of the 11 key railway projects in which the group participates. In the second half of the year, the group will focus on all annual key construction tasks, provide good service and support for major project construction, and make greater contributions to building "Jiangsu on Track."
