Main bridge continuous beam closure section construction method
The invention relates to the technical field of building construction, and discloses a main bridge continuous beam closure section construction method, which comprises side span closure section construction, mid-span closure section construction and secondary side span closure section construction. The main bridge continuous beam closure section construction method comprises the following steps of: firstly closing a side span closure section, then closing a mid-span closure section, and finally closing a secondary side span closure section, wherein the construction sequence of the side span closure section, the middle span closure section and the secondary side span closure section is the same; the construction sequence of the closure section comprises the following steps that one hanging basket on a cantilever beam of a closure section is moved backwards, and the other hanging basket is changed into a hanging bracket. According to the main bridge continuous beam closure section construction method, when closure section concrete is poured, the balance weight water tank carries out synchronous equivalent water drainage, so that the stability of the cantilever section can be effectively kept, the closure section adopts a single hanging basket to modify a closure hanging bracket, a main longitudinal beam, an upper cross beam and a rear anchoring system form the hanging bracket, the construction time is conveniently shortened, and the construction efficiency is improved.
本发明涉及建筑施工技术领域，且公开了一种主桥连续梁合拢段施工方法，包括边跨合拢段施工、中跨合拢段施工和次边跨合拢段施工，主桥连续梁合拢段施工方法为：先合拢边跨合拢段，然后合拢中跨合拢段，最后合拢次边跨合拢段，边跨合拢段施工、中跨合拢段施工和次边跨合拢段施工顺序相同；合拢段施工顺序包括以下步骤：后移合拢段悬臂梁上的一个挂篮，并将另一个挂篮改为吊架。该主桥连续梁合拢段施工方法，在浇注合拢段混凝土时配重水箱进行同步等量放水，从而可以有效保持悬臂段的稳定性，合拢段采用单只挂篮改装合拢吊架，保留主纵梁与上横梁及其后锚固系统形成吊架，方便缩短施工时间，提高施工效率。
