Bridge pier column reinforcing structure and construction method
A bridge pier column reinforcing structure and a construction method are suitable for design and construction of bridge pier column reinforcing, and are characterized in that the structure is of a self-stress concrete circular ring thin-wall structure, is arranged outside a reinforcing pier column, and is composed of an erection rib framework, reinforcing ribs and self-compacting expansive concrete; the construction method comprises the following steps: planting anchoring ribs; erecting supporting ribs are welded; forming an erection rib framework; binding reinforcing ribs; pouring self-compacting expansive concrete; and preserving in water for 7 days. After the expansive concrete is poured, the expansive concrete interacts with the reinforcing longitudinal ribs and the reinforcing circumferential ribs, circumferential and longitudinal self-stress is formed around the reinforcing pier column, bond stress is applied to the reinforcing pier column, and the bearing capacity of an original pier column is greatly improved.
一种桥梁墩柱加固结构及施工方法，适用于桥梁墩柱加固的设计与施工，其特征在于所述的结构为自应力混凝土圆环薄壁结构，布设在加固墩柱的外部，是由架立筋骨架、加固筋与自密实膨胀混凝土三部分组成；施工步骤为：植锚固筋；架立支撑筋焊接；形成架立筋骨架；绑扎加固筋；浇筑自密实膨胀混凝土；水养生7天。膨胀混凝土浇筑后，膨胀混凝土和加固纵向筋与加固环向筋相互作用，在加固墩柱周围形成环向和纵向的自应力，给加固墩柱一个握裹力，大大的增加了原墩柱的承载能力。
