Construction structure of bridge pier column
The invention belongs to the technical field of bridge construction, and particularly relates to a construction structure of a bridge pier column. Positioning ribs are connected to the upper ends of the bearing platform main ribs arranged corresponding to the pier column construction position, and the positioning ribs vertically extend out of the upper portion of the bearing platform concrete body; a vertically-arranged pier column is constructed at the pier column construction position of the bearing platform, the lower end of a pier column main reinforcement extends to the position below the first pier column stirrup set, and a connecting section located below the first pier column stirrup set is formed; the cast-in-place pier column further comprises a vertically-arranged grouting sleeve, the positioning rib and the connecting section are in coaxial butt joint through the grouting sleeve, and the grouting sleeve is located in the cast-in-place pier column concrete body and is adjacent to the upper surface of the bearing platform concrete body. A mortar body used for wrapping the positioning rib and the connecting section is poured into an inner cavity of the grouting sleeve. And construction of the cast-in-place bridge pier column is facilitated. And the upper surface of the bearing platform is horizontal and provides a supporting surface for the grouting sleeves, so that the mounting heights of the grouting sleeves are consistent.
本发明属于桥梁施工技术领域，具体涉及一种桥梁墩柱的施工结构。与墩柱施工位置相对应布置的承台主筋上端连接有定位筋，定位筋从承台混凝土本体的上方竖向伸出；承台的墩柱施工位置处施作有竖向布置的墩柱，墩柱主筋的下端延伸至第一墩柱箍筋组的下方，且形成位于第一墩柱箍筋组下方的连接段；还包括竖向设置的灌浆套筒，定位筋与连接段通过灌浆套筒同轴对接，灌浆套筒位于现浇墩柱混凝土本体内、且与承台混凝土本体的上表面相邻布置；灌浆套筒的内腔中灌注有用于包覆定位筋与连接段的砂浆本体。便于现浇桥梁墩柱的施工。承台的上表面水平，为灌浆套筒提供支撑面，使多个灌浆套筒的安装高度一致。
