Recently, the preliminary design of the newly built Tianjin-Weifang high-speed railway Jinan connecting line (hereinafter referred to as the Jibin high-speed railway) has been jointly approved by the State Railway Group and the Shandong Provincial People's Government, which marks a key step in the construction of the Jibin high-speed railway project and is about to enter the implementation stage. It has laid a solid foundation for the approval of the Ministry of Natural Resources and the start of construction of the controlled project at the end of September.
Jibin High Speed Rail
The main line of Jibin high-speed railway is 145.3 kilometers long, with a total investment of 34.631 billion yuan. Shandong Jibin high-speed railway company is responsible for the construction. The construction period of the project is 4 years. The line starts from Jinan City in the west, leads from Jinan East Station, the hub of Jinan, goes north to Licheng District, Yaoqiang Airport and Zhangqiu District of Economic South City, crosses Economic Yang District of the Yellow River and Shanghe County, and runs eastward through Huimin County, Binzhou City and Binzhou City. City, access to Binzhou Station. The technical standard is constructed according to the high-speed railway, double-track, 350 km/h (the local speed limit is 200 km/h for the Jiyang to Jinan east introduction hub section).
There are 6 stations in Jinan East, Yaoqiang Airport, Jiyang, Shanghe, Huimin and Binzhou on the whole line. The territory of Binzhou is about 54.8 kilometers long (including 37.8 kilometers for Huimin and 17 kilometers for Bincheng).
In the early stage, the municipal transportation department paid close attention to the process of handling the preliminary design approval documents such as environmental impact assessment, navigation, water conservation, etc., and successfully completed the environmental impact assessment approval, the impact assessment of the navigation conditions of the waterway, and the on-site investigation and expert review of the flood control assessment of the city and county-level rivers and canals. and other work, the pre-requisite documents for the Binzhou section were all completed on schedule with quality and quantity, laying a local work foundation for the preliminary design approval.
The approval of the preliminary design of the project is another major breakthrough after the approval of the National Development and Reform Commission. Work has been accelerated. On the day when the preliminary design was approved, the materials for the preliminary land use in the Binzhou section were reported to the Provincial Department of Natural Resources overnight and passed the review at one time.

According to Yang Hui, chief designer of Jibin High-speed Railway of the First Railway Institute, “Jibin High-speed Railway is located in the northern part of the Shandong Peninsula urban agglomeration. It passes through the Yaoqiang Airport Tunnel and the Jiyang Highway-Railway Dual-purpose Yellow River Bridge is a key and difficult control project for the Jibin High-speed Railway. The open-cut section of Yaoqiang Airport Tunnel and Station is about 8.0 kilometers long. The stratum is mainly silt, silty sand and silty clay. The tunnel is only 1.6 kilometers away from the Yellow River, and the groundwater level is high. 300 meters. In the design, Tieyi Institute adopts various water-stop and precipitation measures such as underground diaphragm wall + SMW construction method piles, strengthens the observation of foundation pit precipitation and settlement, and ensures the safety of tunnel construction and operation.
Jiyang Highway-Railway Double-purpose Yellow River Bridge adopts the layout of upper-level highway (G308 national highway) and lower-level railway. capacity, and play an important role in facilitating travel by road and rail across the strait in Jinan. "

The project is an integral part of the Tianjin-Weifang high-speed railway and the northern coastal passage of the intercity railway network in Shandong Province, and the intercity railway in the Jinan metropolitan area. Contact line.
After completion, it will realize the interconnection and intercommunication of the northern Shandong area, and form a passenger express channel between the Dongbin urban agglomeration and Jinan. Editor/He Yuting
