On January 10, with the final batch of concrete poured in place with precision, the main structure of the recovery framework for the FDPE unit in Huanqiu Jilin Chemical Construction Nantong Blue Sea New Materials’ full-density polyethylene project was successfully completed, marking progress in the civil construction phase of this project. This recycling framework is a reinforced concrete frame structure, 64 meters long, 16 meters wide, and 7 meters high; it serves as an important supporting structure for the FDPE facility. Since the commencement of the main structure construction on December 2, 2025, the project team has worked continuously for 39 days, overcoming various challenges such as low winter temperatures, tight deadlines, and complex structural requirements. A total of 585 cubic meters of concrete have been poured, enabling the achievement of the construction milestones with high quality and thus creating favorable conditions for subsequent equipment installation and steel structure construction. During construction, this frame structure features large spans, dense reinforcement at the beam-column joints, and a large number of bolts that need to be embedded; as a result, high precision is required and the construction process is quite challenging to organize. To ensure project quality and schedule, the project’s technical and quality management personnel take charge on site, go directly to the construction area, communicate and discuss repeatedly with the construction teams, scientifically optimize the construction sequence and plans, and exercise full-process supervision over key processes such as steel bar binding, formwork installation, and bolt positioning.
