The Construction Technology Of Concrete Continuous Box Girder Bridge In Complex Environment

As an important component in the form of recent years has advanced transportation, bridges as traffic roads, in terms of size, structure are presented in the form of diversity. Due to the complex terrain of the objective, in bridge construction, construction technology continues to progress, the construction method also appeared in various forms. In complex terrain, especially high fill status, choose the most reasonable method of construction is directly related to the quality of construction, construction safety, construction speed, and cost control.This paper relies on Chongqing Wangjiagou Bridge project, the construction technology of continuous box girder bridge complex terrain conditions were analyzed with a drilling program by processing high fill areas, Piers Pier mold construction technology, high fill selection and implementation of the district Scaffording program design, wide box girder bridge placement, construction and other large-span prestressed construction scheme proposed method is suitable for the construction of the bridge, in order to achieve optimal construction plan, to achieve high quality, efficient, economic, security target. According to the preliminary program and then combined with the construction environment and resources as well as the relevant provisions of the construction specifications to further improve the program to determine the technical parameters of construction, quality and related management measures.Note the use of the industry advocated by new technologies, new processes, new materials used in the construction process, streamline processes and improve the quality of reuse, environmental protection equipment and materials, to achieve the optimal allocation of resources to achieve optimal solutions. Within the framework of the implementation of the program to determine the construction of elaborate construction technical processes, calculations, the construction process and achieve the desired effect reproduction. Practice shows that the bridge construction control analysis is feasible and can be used for reference in the future the same type of construction of the bridge.
