The construction of a strong country should be preceded by transportation. Starting in 2023, the investment in transportation infrastructure in various places will grow steadily. Shandong has strengthened the guarantee of essential factors, and a number of major transportation infrastructure projects are progressing rapidly. In the first two months, the investment in transportation construction was 34.6 billion yuan, helping to achieve a good start in the first quarter.

The G228 Binzhou section with a total investment of nearly 3 billion yuan is a major livelihood project in northern Shandong. Today, with the completion of the last truck of concrete pumping, the project control project - the main pier body of the Taoer River Bridge has been poured. Since the bridge body is located in the alluvial plain of the Yellow River and close to the Bohai Sea, the groundwater has high salinity, which restricts the construction of the project. The project overcomes technical difficulties by updating materials and improving the platform. Liu Wei, a bridge expert from the China Construction Eighth Bureau, said: "The concentration of chloride ions and sulfate ions is 8 to 10 times that of seawater. Comprehensive treatment measures such as brine slurry making, underground multi-stage circulation system, and water head improvement have been adopted. In order to ensure Anti-corrosion measures, permanent casings were taken during construction.”

Focusing on process innovation, the project has formed more than 60 patents. After the bridge is completed, it will effectively connect the two sides of the river to meet the transportation and travel needs of enterprises and residents along the line. Gai Zhong, the production manager of Binzhou G228 project of China Construction Eighth Bureau, said: "The distance between the two sides of the Strait has been effectively shortened by more than 80 kilometers, from the original one and a half hours to five minutes, which will optimize the layout of the coastal road network in northern Shandong and promote the regional economy around the Bohai Sea. develop."

With a decisive battle at the beginning and a sprint at the beginning, Shandong seized the golden construction period and accelerated major projects. Yesterday afternoon, after 48 hours, the pouring of the first main pier cap of the Jiyang Yellow River Highway-Railway Bridge, a control project for the entire line of the Jiyang-Binan high-speed railway, was successfully completed. The cap is 5 meters high and requires more than 5,500 square meters of concrete earthwork. Traditional construction is mostly pouring in sections. In order to ensure the integrity of the project, this time, the construction party explored one-time continuous pouring. Chen Hongxu, engineering director of the Jibin high-speed railway second bid project of China Railway Bridge Bureau, said: "We use 2 mixing stations, one station is equipped with 10 tankers, and the supply capacity can reach 150 cubic meters per hour. The integrity is better, compared with layered pouring Save about 10 days (construction period).”

In the first two months of 2023, Shandong has invested 34.6 billion yuan in transportation infrastructure construction, which is higher than the same period in 2022, and the investment continues to increase. Recently, 119 tasks in the province's highway, railway, port and shipping fields were selected into the list of the first batch of pilots to accelerate the construction of Shandong Demonstration Zone as a powerful transportation country. Shandong has accelerated the promotion of projects in terms of policy incentives and essential services, helping to achieve a good start in the first quarter. Editor/Xu Shengpeng
