Construction Technique of Climbing Forms for the Thin-Walled, Hollow Piers of the Gula River Bridge

The construction of the high pier is the focal point and difficult point of bridge construction, its key to success lies in choosing the right way of construction. The basic methods and their respective characteristics of the pier construction are introduced in the paper. In the meantime, the construction technology processes, key techniques of the hydraulic self-moving climbing form and its characteristics are also briefly presented in the paper. The hydraulic self-moving climbing forms are efficient in construction, good in quality, effective in ensuring safety, and economical in saving construction costs. It is of great value in the construction of high-rise structures and tall piers, and therefore worth widely popularizing.
