Construction process of bridge downward turning method swivel bearing system
The invention relates to a construction process of a bridge swivel bearing system, in particular to a construction process of bridge downward turning method swivel bearing system and mainly solves theproblem that the existing swivel construction quality is not easy to guarantee and the like. The construction process comprises the following steps: cleaning a bearing platform base; binding lower bearing platform reinforcing steel bars, and dragging counter-force seat reinforcing steel bars; mounting a lower bearing platform template and a traction counterforce seat template; pouring lower bearing platform concrete for the first time; identifying a spherical hinge mounting reference; fixing a slideway support, a lower spherical hinge support, a slideway plate and a lower spherical hinge; mounting a lower bearing platform upper half part reinforcing steel bar and a boosting counterforce seat reinforcing steel bar; pouring lower bearing platform concrete; installing a jack boosting counterforce seat template and pouring concrete; mounting a positioning shaft; lubricating grease is filled between the upper and lower spherical hinges; installing an upper spherical hinge and performing trial rotation; sealing a gap between the upper and lower spherical hinges; mounting supporting legs, temporary supports, an upper bearing platform, a rotary table bottom die, side dies, upper bearing platform reinforcing steel bars and anchoring rotary body traction bundles; pouring concrete on the upper bearing platform; swivel spherical hinge installation completion. By means of the constructionprocess, construction quality is easy to guarantee.
一种桥梁下转法转体承重系统的施工工艺涉及桥梁转体承重系统施工工艺。主要是为解决目前转体施工质量不易保证等问题而发明的。它包括如下步骤：承台基底清理；绑扎下承台钢筋、牵引反力座钢筋；安装下承台模板及牵引反力座模板；第一次浇注下承台混凝土；标识球铰安装基准；固定滑道支架及下球铰支架、滑道板、下球铰；安装下承台上半部钢筋、助推反力座钢筋；浇注下承台混凝土；安装千斤顶助推反力座模板并浇注混凝土；定位轴安装；上下球铰之间润滑油脂填充；安装上球铰及试转；封闭上下球铰间缝隙；安装撑脚、临时支撑、上承台、转台底模和侧模、上承台钢筋、锚固转体牵引束；上承台混凝土浇注；转体球铰安装完成。优点是施工质量易保证。
