Bridge hanging basket suspension casting construction method
The invention provides a bridge hanging basket suspended pouring construction method, which belongs to the technical field of bridge construction, and comprises the following steps of: assembling a hanging basket, pre-pressing the hanging basket, mounting a template, reinforcing steel bars and pipelines, performing segment concrete construction and maintenance, pre-stress construction, pipeline mud jacking, anchor sealing and linear control, and tensioning and mud jacking construction of an upper beam segment. And the hanging basket moves forwards to the next beam section in place, after the last suspended pouring section is poured and tensioned, the hanging basket moves forwards to the closure section, the main truss is dismantled, the bottom basket and the outer side mold are used for closure section construction, and after closure section construction is completed, the bottom basket is dismantled. According to the method, high-altitude bridge construction can be achieved, meanwhile, through accurate stress verification, the problem of deviation in the construction process is avoided, the construction precision is higher, the construction effect is better, meanwhile, no supporting base needs to be erected, and the construction efficiency is high.
本发明提供桥梁挂篮悬浇施工方法，属于桥梁施工技术领域，挂篮拼装，挂篮预压，进行模板安装和钢筋及管道安装，然后节段混凝土施工与养护，预应力施工，管道压浆与封锚和线型控制，上节梁段张拉压浆施工完成后，挂篮前移行走至下一梁段就位，最后一个悬浇段浇筑并张拉完成后，挂篮前移至合拢段，拆除主桁架，利用其底篮、外侧模进行合拢段施工，合拢段施工完成后再拆除底篮。本发明能够实现高处的桥梁施工，同时通过精准的应力验证，避免在施工过程中出现偏移的问题，使得施工精度更更高，施工效果更好，同时不需要搭设任何的支撑底座，施工效率跟高。
