Construction Technology of No.0 Block High Support of the Cable-stayed Bridge with Tower-beam-pier Consolidation System for Qingshuijiang Super Large Bridge
Abstract: As an important part of highway engineering, steel pipe pile support of large temporary support structure in box girder construction has been widely used. In the construction of bridge engineering, reasonable construction of temporary support structure is the basic condition and guarantee of bridge engineering construction, It plays a decisive role in the progress and quality of bridge construction. Combined with the engineering example of No.0 block high support construction of Qingshuijiang Bridge, this paper introduces in detail the scheme and structure of 0 block high support construction of cable-stayed bridge with tower beam pier consolidation system,compares the schemes and introduces the construction technology.
Keywords: bridges; cable stayed bridges; tower-beam-pier consolidation system; corbel bracket; steel pipe piles; construction
