Abstract:In the Jiyang Road Elevated Bridge Project, the steel box girder technology has been widely applied. Especially in the area crossing the Chuanyang River, an advanced steel box girder structure for crossing the Chuanyang River has been adopted. During the construction process, the support frame method is used in the construction. This construction method not only ensures the efficient progress of the project, but also demonstrates the extremely high safety and reliability. In addition, by adhering to the principle of rapid construction, the project team strives to shorten the construction period and upgrade the construction efficiency on the premise of ensuring the engineering quality. At the same time, the project team adheres to the concept of green construction and strives to minimize the impact on the environment during the construction process to the greatest extent.
