Research on Key Technologies for Asynchronous Hanging Basket Construction of Corrugated Steel Web Box Composite Beams
The asynchronous hanging basket method has multi-segment simultaneous construction,which realizes the streamlined operation of three working faces,and solves the problem of limited working surface and long period of traditional hanging basket construction.In order to further reflect the excellent benefits and construction safety and reliability of this new construction method,this paper proposes an asynchronous hanging basket structure and construction technology for the technical problems of bridge deck transportation,hoisting and positioning,and overlapping space of steel-concrete construction of corrugated steel web in the construction project of corrugated steel web composite box girder.The results show that the working face of the construction technology is safer,avoids the problem of mutual interference between the top and bottom plates of the traditional hanging basket,and effectively shortens the construction period of the section.The rapid hoisting and accurate positioning of the long cantilever construction of the corrugated steel web are realized,the problems of space bending and closing difficulties are solved in the installation process of the corrugated steel web,and valuable experience is accumulated for the construction of similar projects in the future.
