2023, the main pier bearing platform on the downstream side of the south bank of Shuangliu Yangtze River Bridge on Xingang Expressway, invested by Hubei Trading and Investment Group and constructed by China Railway Bridge Bureau Group, was completed, marking that the project formally entered the construction stage of the main tower column. The bearing platform of the main pier
on the south bank is made of mass concrete, which is divided into two bearing platforms on the upstream side and the downstream side, and is poured in two layers each time. This pouring is the second layer of the downstream side bearing platform, which is also the last concrete pouring of the side bearing platform. The second layer of the main pier cap involves the embedment of the tower base and the tower column. There are many kinds and large quantities of steel bars, and the requirements for the positioning accuracy of the embedded steel bars of the tower column are high. The construction is complicated. The project department overcomes the difficulties, reasonably arranges the overlapping construction of each process, and operates continuously for 24 hours to ensure the smooth realization of the node construction period.
In order to ensure the smooth pouring of the main pier cap, the project department has carefully worked out the pouring construction scheme and carried out detailed construction technical disclosure before pouring. In order to ensure the construction quality of the bearing platform, the project department shall disclose the key points and precautions of the construction of the bearing platform to the operation team and the management personnel before the construction, and formulate the responsibility matrix to clarify the responsibility zoning. In the process of pouring, technicians and testers control the whole process of concrete performance, vibration process and other important construction links to ensure the smooth completion of the main pier cap pouring in an all-round way. The pouring of the bearing platform on the downstream side of
the main pier was completed first to ensure that the construction period of the main pier bearing platform was completed before the flood season, which greatly inspired the morale of all the construction personnel and stimulated the energy of all the staff of the project. With more enthusiasm, all the construction personnel of the project department will continue to pull the bow and rivet vigorously, seize the golden period of construction, and go all out to rapidly promote the construction of the superstructure of the main tower column.
