Bridge pier column replacement construction device and method
The invention particularly discloses a bridge pier column replacement construction device and method. Comprising the following steps that a settlement displacement observation point is arranged between a beam plate and a top tie beam, the settlement displacement observation point is used for obtaining deformation data between the beam plate and the top tie beam, and stability in the construction process is guaranteed according to the deformation data; a plurality of temporary supporting structures are uniformly arranged between the top straining beam and the ground; a plurality of brackets are arranged between the top straining beam and the beam plate; concrete of the beam plate support is broken and removed; the top straining beam is separated from the to-be-replaced pier column, and the to-be-replaced pier column is dismantled; a new pier column is built at the position of the pier column to be replaced; and the reinforcement cage erecting formwork, the support and the temporary supporting structure are dismantled, and bridge pier column replacement is completed. According to the method, the temporary supporting structure is arranged between the top straining beam and the ground, the support is arranged between the top straining beam and the beam plate, and then the to-be-replaced pier column is disassembled and re-poured, so that construction of overall replacement of the bridge pier column is achieved, and compared with an originally-adopted construction method, the efficiency is higher.
本发明具体公开了一种桥梁墩柱置换施工装置及方法。包括以下步骤：在梁板与顶系梁之间设置沉降位移观测点，沉降位移观测点用于获取梁板与顶系梁之间的变形数据，并根据变形数据保证施工过程中的稳定性；在顶系梁与地面之间均匀设置若干临时支撑结构；在顶系梁与梁板之间设置若干支架；对梁板支座的混凝土进行破除；将顶系梁与待换墩柱分离，并拆除待换墩柱；在待换墩柱的位置建立新墩柱；拆除钢筋笼支立模板、支架和临时支撑结构，完成桥梁墩柱置换。本申请通过在顶系梁和地面之间设置临时支撑结构，在顶系梁和梁板之间设置支架，然后对待换墩柱进行拆分并重新浇筑的方法，实现桥梁墩柱整体置换的施工，相较于原先采用的施工方法，效率更高。
