Study on Key Techniques for Hanging Basket Construction of Extra Large Con-tinuous Rigid Frame Bridge with Double Thin-walled Piers
The continuous rigid frame bridge with double thin-walled piers has advantages such as light weight and high structural strength.However,due to technical difficulties such as generally high piers and small operating interfaces,the construction is more difficult.This study is based on the hanging basket construction of a double thin-walled super large continuous T-shaped rigid frame bridge,and optimizes the key technology of hanging basket construction for this type of bridge.By optimizing the construction of hanging basket system,template engineering,concrete engineering,and monitoring and controlling the bridge line shape.The research shows that this key optimi-zation scheme overcomes the problems of high piers,high construction difficulty,unfavorable stress,and small op-erating area,and ensures the reasonable linear shape of the bridge,as well as the smooth and safe progress of the bridge.At the same time,the key construction technology has verified the effectiveness and reliability of this method,which has significant reference and practical significance for the hanging basket construction of double thin-walled continuous rigid frame bridges.
