Construction method of large-span buried straddle type steel-concrete combined transfer beam
The invention discloses a construction method of a large-span buried straddle type steel-concrete combined transfer beam, which relates to the technical field of bridge construction and comprises the following steps of: segmenting and partitioning a plurality of transfer beams and numbering in sequence; according to the field ground height difference, the requirements of component transportation and hoisting stations are analyzed, and the field of the original ground is leveled and hardened; temporary supports and bearing supports are arranged in a transfer beam foundation pit formed through pouring, the bearing supports are located at the two ends of the transfer beam foundation pit, the transfer beam is divided into a plurality of independent small blocks, and the small blocks of the transfer beam are supported by erecting detachable temporary supports at the bottom of the foundation; a plurality of transfer beams which are divided into small blocks are welded and combined on an erection site through a welding process, and finally, temporary supports are removed after construction is completed, so that structural damage caused by overlarge building load at the bottom of a construction site can be avoided in the construction process that the transfer beams are divided into the small blocks for construction, and construction is more convenient and faster.
本发明公开了一种大跨度埋地骑跨式钢混组合转换梁施工方法，涉及桥梁施工技术领域，包括将多个转换梁分段分块并按顺序进行编号；根据现场地面高差，分析构件运输及吊装站位的需求，对原地面的场地进行平整并进行硬化处理；在已浇筑成型的转换梁基坑内设置临时支架和承重支架，承重支架位于转换梁基坑两端处，本申请将转换梁分成多个独立的小块，通过在基础底部搭设可拆卸的临时支撑对小块的转换梁进行承托，再在架设地将多个分割后成小块的转换梁通过焊接工艺进行焊接组合，最后搭建完成后将其临时支撑进行拆除，在转换梁分成小块进行搭建施工过程中可避免因施工现场底部建筑荷载过大引发的结构破坏，且使得施工更加便捷。
