Description

Technical Field

[0002] Cantilever continuous beam is a common bridge structure. It consists of multiple cantilever beam segments and a continuous beam segment in the middle. A cantilever beam segment refers to a beam segment with one end fixed and the other end free. During the construction process, the cantilever beam segment is first built, and then the cantilever beam segments are connected into a whole through the closing process to form a continuous beam. In actual engineering, cantilever continuous beams are widely used in the construction of highway, railway and other bridges. The characteristics of this type of beam are that the fulcrums at both ends and the length of the span can be adjusted to adapt to different use environments and needs. Cantilever continuous beams are usually used in large-scale engineering projects such as bridges, tunnels, and elevated roads. Due to its simple structure, convenient construction, and good bearing capacity, it is currently one of the more mature high-pier and large-span bridge structures. 0# block construction is the first stage of cantilever casting of continuous beams. Conventional construction methods are divided into two types: ground brackets and cantilever triangular brackets. The ground bracket method is suitable for low piers, and the cantilever triangular bracket is suitable for high piers. According to the height of the pier body, a triangular bracket is installed by pre-embedded corbels on the pier body or a support system consisting of steel pipe columns + support beams is used.
