Abstract

The invention relates to a hollow high pier formwork supporting system which comprises a hollow pier head section pier body formwork supporting system, a hollow wall pier straining beam formwork supporting system, a hollow high pier formwork system and a hollow high pier formwork overturning system. The hollow pier head section pier body formwork supporting system comprises a bearing platform, a reinforcing steel bar framework, a head section formwork system, supporting column locating fixing frames, vertical main bars and a concrete pouring rail frame. The hollow wall pier straining beam formwork supporting system comprises pier columns, outer formwork symmetric corbel supports, a profile steel main beam and a straining beam formwork. The hollow high pier formwork system comprises an overturning lifting outer formwork, a lifting inner formwork, movable trusses, a construction platform and external wind-resisting columns. The hollow high pier formwork overturning system comprises a tower crane, a concrete conveying structure, a crawling ladder structure, a pier cavity lifting type anti-falling platform system and a pillar type formwork overturning system. The hollow high pier formwork supporting system has the beneficial effects that the overturning lifting outer formwork and the overall lifting inner formwork are adopted to be combined into a formwork supporting structural system, formwork supporting efficiency of high pier formwork overturning is greatly improved, and the stability of a formwork supporting formwork structure is effectively improved.

Description

technical field [0001] The invention relates to a hollow high pier formwork system and a construction method, belonging to the field of bridge engineering, suitable for the construction of highway and railway bridge high pier, and also suitable for the construction of ultra-high concrete structures such as high tower columns, where the construction site is narrow and road transportation Difficult workplace construction can show its superiority. Background technique [0002] With the rapid development of urbanization and the vigorous development of highway transportation, bridges are developing in the direction of long-span and high piers, and high piers over 100m have appeared one after another. The overturning formwork for high pier is developed on the basis of summarizing the characteristics of sliding formwork, hydraulic overturning formwork, climbing formwork and inverted formwork. A complete set of molds for the combination of formwork and inner and outer working platf...
