On October 15, a significant milestone was achieved in the Zhaowuda Road and South Second Ring Interchange project in Hohhot, Inner Mongolia, which is a key municipal construction project for 2025. The first pier of the project has successfully completed its concrete pouring, marking a substantial breakthrough in the construction of the bridge's lower structure. This lays a solid foundation for the subsequent standardized mass construction of piers and accelerates the overall progress of the project.
The Zhaowuda Road and South Second Ring Interchange project is an extension of the Zhaowuda Road and Zhelimu Road renovation project. Since the commencement of construction, the project team has effectively coordinated efforts while ensuring quality and safety. As of the completion of the first pier’s pouring, a total of 134 pile foundations and 9 bearing platforms have been successfully constructed, allowing for orderly progress in foundational engineering.
The completed pier is identified as Pier 09# of the East-South (ES) ramp, designed in a visually appealing and structurally stable vase shape. It adheres strictly to design standards, with dimensions of 3.2 meters by 1.6 meters, a height of 4.4 meters, and a cap height of 3 meters, requiring a concrete volume of 46.8 cubic meters. During the process, the project team innovatively employed a customized segmented steel formwork technique, combined with a concrete pump for one-time pouring, effectively ensuring the pier's structural smoothness and density while significantly enhancing construction efficiency. This sets a replicable and applicable technical benchmark for future similar pier constructions.
To ensure high-efficiency progress throughout the project's lifecycle, a specialized support system has been established. On the southwest side of the project, a 2,100-square-meter intelligent rebar processing area has been put into use, featuring epoxy floor coatings to maintain a clean working environment and enhance safety management. The processing area operates on an assembly line design, equipped with two 10-ton gantry cranes, two sets of intelligent CNC rebar cutting and threading production lines, two sets of intelligent vertical rebar bending centers, as well as one set each of intelligent straightening and arc equipment. This allows for the simultaneous operation of two automated production lines, fully meeting the daily rebar processing needs for critical parts such as bearing platforms, piers, and cast-in-place box girders, thereby providing strong material and technical support for project construction.
The successful pouring of the first pier not only marks an important milestone in the project's construction but also reflects the team's commitment to overcoming challenges and fulfilling obligations efficiently, paving the way for a strong start to further developments in the project.
