Bridge swivel structure construction method based on spherical hinge
The application provides a bridge swivel structure construction method based on spherical hinges. The bridge swivel structure construction method comprises the following steps that lower-layer concrete of a lower bearing platform is poured, wherein the height of the lower-layer concrete is two thirds of that of the lower bearing platform; a lower spherical hinge positioning framework, pre-buried profile steel and a lower spherical hinge are installed on the lower-layer concrete of the lower bearing platform, and the remaining one third of the lower-layer concrete of the lower bearing platformin height is poured; after the upper spherical hinge, an annular slideway and supporting legs are mounted, upper turntable lower-layer concrete of an upper turntable is poured into the upper sphericalhinge and the supporting legs; upper turntable upper-layer concrete of the upper turntable is poured; and after the bridge swivel structure completes swivel, disc sealing concrete is poured. The lower bearing platform is poured twice, so that hydration heat generated by concrete is prevented from being massively gathered in a short time; the central area reserved when the lower bearing platform is poured is used for placing part of the structure of the spherical hinge and pouring reinforced concrete, and the reinforced concrete is used, so that the supporting capacity of the lower bearing platform is improved.
本申请提供一种基于球铰进行的桥梁转体结构施工方法，包括如下步骤：浇筑下承台三分之二高度的下承台下层混凝土；在所述下承台下层混凝土上安装下球铰定位骨架、预埋型钢和下球铰，浇筑所述下承台剩下的三分之一高度的下承台上层混凝土；安装上球铰、环形滑道以及撑脚之后，在所述上球铰内和撑脚内浇筑上转盘的上转盘下层混凝土；浇筑上转盘的上转盘上层混凝土；在桥梁转体结构完成转体后，浇筑封盘混凝土。本申请分两次浇筑下承台，避免混凝土所产生的水化热在短时间内大量聚集；在浇筑下承台时预留的中心区域，用于置入球铰的部分结构，还用于灌注强化混凝土，使用了强化混凝土，有利于提高下承台的支承能力。
