Since June, due to the tight schedule of the project, the difficulty in purchasing non-standard pipes and the shortage of technical experience, all departments of the metal structure company have cooperated closely to study and formulate the manufacturing and construction plan. While speeding up the production of the factory area, the installation personnel have entered the construction site in advance, preparations for installation. On July 13, with the arrival of 0# bearing platform, 10 strong skeletons and arch feet, the steel structure of the bearing platform officially entered the installation stage. As the bearing platform reinforcement has been fully bound, the stiffening skeleton and arch foot cannot be directly hoisted, and can only be carried out in bulk. Affected by rainy weather, the construction difficulty is further increased. In order to complete the installation task on schedule, the on-site personnel overcame difficulties, worked overtime and rushed to catch up with the construction period. After 11 days of hard work, a total of 20 arch feet and 20 strong skeletons of 0# and 1# bearing platforms were successfully installed. The successful completion of the installation of
marks the full completion of the steel structure foundation of Jining Old Canal Bridge. After concrete backfilling, it will officially enter the arch rib installation stage of the main bridge. In the next step, the metal structure company will speed up the production progress in the factory, make sufficient preparations for on-site installation, ensure the successful completion of various tasks, and make the arch bridge look beautiful as soon as possible!
