Bridge tower column construction method
The invention provides a bridge tower column construction method, and belongs to the technical field of bridge tower column construction, and the method comprises the following steps: constructing a lower tower column and a middle tower column, and starting lower cross beam construction and upper tower column construction after a creeping formwork crosses a cross beam. Bailey beams are high in specialization and standardization degree and simple in connection, safety is easy to guarantee, the construction period is greatly shortened, supports and hydraulic creeping formworks are separately constructed in the upper cross beam construction process, mutual conflicts are avoided, construction organization arrangement is more reasonable, middle-upper tower column creeping formwork conversion can be completed at a time, the operation area is small, the construction organization difficulty is reduced, and the construction efficiency is improved. And the construction is convenient and the safety control is facilitated, but the space cross operation exists, so that the cost of damaging the template by about 15m < 2 > due to the fact that holes need to be formed in the external mold template at the prestress tension end is reduced.
本发明提供一种桥梁塔柱施工方法，属于桥梁塔柱施工技术领域，方法包括如下：对下塔柱、中塔柱进行施工，爬模越过横梁后开始下横梁施工和上塔柱施工。通过贝雷梁专业化标准化程度高，连接简单，安全性容易保证，工期大大缩短，上横梁施工中，支架与液压爬模分开施工，避免了彼此冲突，施工组织安排更加合理，可以一次性完成中上塔柱爬模转换，作业面积小，降低了施工组织难度，对施工方便及安全控制有利，但是存在空间交叉作业，减少了预应力张拉端需要在外模模板上开孔，损坏模板约15m2的费用。
