Research on the Application of Hanging Basket Corbel Construction Technology in Continuous Rigid Frame Side Span Cast-in-place Section
Continuous rigid frame bridge is one of the commonly used structural systems in large-span bridges.However,in the traditional construction method of side span cast-in-place section,there are some problems in the floor support method and bracket method,such as high cost,difficult construction,poor welding quality at high altitude and high safety risk.In order to solve these problems,this paper takes a high-speed super-large bridge project in Hunan as an example,and puts forward a new construction method,that is,the construction technology combining hanging basket and corbel in the side span cast-in-place section,aiming at realizing the efficient construction of the large-span bridge and effectively making up for the shortcomings of the traditional process.
