Spatial special-shaped arch foot bridge site installation method
The invention discloses a space special-shaped arch foot bridge site installation method, and belongs to the technical field of bridge engineering. Comprising the following steps that S1, arch foot embedded parts are designed and manufactured in a segmented mode; s2, when the bearing platform is constructed, a positioning frame and an anchor bolt are pre-buried; s3, a bearing plate is hoisted; s4, the bearing plate serves as an assembling platform, and the core tube is hoisted; s5, welding and fixing the core tube; and S6, integrally hoisting and falling to a designed position. According to the invention, the problem that large-tonnage integral hoisting bolt holes are difficult to align and mount is effectively solved, and the safety risk of long-time load operation of a crane is also eliminated; the arch foot pre-embedded anchor bolts and the core tube bearing plate are used as an on-site assembly jig frame, the assembly jig frame does not need to be additionally erected on the construction site, and a large amount of labor and material cost is saved; and meanwhile, hoisting is directly carried out after splicing is completed in a bridge site, the hoisting time is shortened, and the safety risk of hoisting from a high position is reduced.
本发明公开了一种空间异形拱脚桥位安装方法,属于桥梁工程技术领域;包括以下步骤:S1、拱脚预埋件分节段设计、制作;S2、承台施工时,预埋定位架和锚栓;S3、吊装承压板;S4、以承压板作为拼装平台,吊装核心筒;S5、焊接固定核心筒;S6、整体起吊下落至设计位置。本发明,有效解决了大吨位整体吊装螺栓孔对位安装困难的问题,也消除了吊机长时间负载作业的安全风险;利用拱脚预埋锚栓和核心筒承压板作为现场拼装胎架,施工现场无需另外搭设拼装胎架,节省大量人工及材料费用;同时,直接在桥位中拼装完成后吊装,减少吊装时间,降低了从高处起吊的安全风险。
