Bridge pier broken column joint construction method in bridge jacking transformation
The invention discloses a bridge pier broken column connector construction method in bridge jacking transformation. The bridge pier broken column connector construction method comprises the following construction steps that S1, the height H of a pier column after jacking is completed is determined; s2, when H is larger than or equal to 15 cm, the pier stud is chiseled away, and pier stud steel bars are exposed; when Hlt; when the height is 15 cm, the section of the pier column is enlarged; s3, when the pier column is chiseled away, vertical main reinforcements and stirrups are used for being connected with pier column steel bars; when the section of the pier column is expanded, steel bars are planted at the expanded section, and the planted steel bars are connected; s4, a steel formwork is adopted for formwork construction, and concrete is poured; and S5, removing the mold. The construction steps are simple, the design is reasonable, different bridge pier broken column connector connecting modes are adopted according to different pier column heights, and it is ensured that the structure stress is reasonable; different construction procedures are adopted for different broken column connector connecting methods, construction is facilitated, the construction cost is reduced, meanwhile, the safety of a bridge structure in the jacking process is guaranteed, and the construction precision is improved.
本发明公开了一种桥梁顶升改造中桥墩断柱接头施工方法，包括以下施工步骤：S1、确定顶升完成后墩柱高度H；S2、当H≥15cm时，对墩柱凿除露出墩柱钢筋；当H<15cm时,扩大墩柱截面；S3、采用墩柱凿除时，使用竖向主筋和箍筋，将其与墩柱钢筋连接；采用扩大墩柱截面时，对扩大截面处进行植筋将所植入的钢筋进行连接；S4、采用钢模板进行模板施工，并灌注混凝土；S5、拆模。本发明施工步骤简单，设计合理，依据不同的墩柱高度采用不同的桥墩断柱接头连接方式，确保结构受力合理；不同的断柱接头连接方法采用不同的施工工序，方便施工并降低施工成本，同时确保顶升过程中桥梁结构安全，提高了施工精度。
