Recently, the first reinforcement cage hoisting operation for the west bank receiving working shaft of the Jinan Aerospace Avenue Yellow River Crossing Tunnel Project (Phase I), invested in and constructed by Jinan Urban Construction Group, was completed, laying a solid foundation for the rapid advancement of subsequent construction.

The west bank receiving shaft enclosure structure of the Aerospace Avenue Yellow River Crossing Tunnel Project (Phase I) adopts 29 diaphragm walls with a thickness of 1200 mm. The first diaphragm wall is located on the west side of the west bank working shaft, with a length of 52.4 m, a panel width of 6 m and a thickness of 1.2 m. The main reinforcement cage is 51.9 m long and weighs 79.7 t in total. The reinforcement cage was hoisted using a dual-crane lifting method. To ensure smooth construction progress, the project team prepared a special construction plan based on actual site conditions and carried out acceptance inspection of the on-site construction conditions.

Once completed, the Jinan Aerospace Avenue Yellow River Crossing Tunnel Project will effectively strengthen the connection between the urban expressway and surrounding expressways and important transportation hubs, drive the development of northern Jinan, promote resource agglomeration and industrial transformation and upgrading, enhance the competitiveness of the Jinan Start-up Area for Growth Drivers Transformation, and accelerate integration among districts.
