Steel-concrete combined pier bottom structure and construction method thereof
The invention relates to a steel-concrete combined pier bottom structure and a construction method thereof, the steel-concrete combined pier bottom structure comprises a bearing platform, a concrete section, a steel-concrete section and a steel structure section, the concrete section is pre-embedded pier column concrete, and the pre-embedded pier column concrete is connected with the bearing platform through pre-embedded pier column concrete vertical ribs, pre-embedded pier column concrete stirrups in the bridge direction and pre-embedded pier column concrete stirrups in the transverse bridge direction; the embedded pier column concrete is provided with positioning steel plates, the positioning steel plates comprise the upper positioning steel plate and the lower positioning steel plate which are located on the upper portion and the lower portion of the embedded pier column concrete respectively, and the vertical steel bars are installed and positioned through the upper positioning steel plate and the lower positioning steel plate. The steel-concrete section is provided with a steel-concrete section transverse-bridge-direction steel plate and a steel-concrete section longitudinal-bridge-direction steel plate, and the steel structure section is provided with a steel structure section transverse-bridge-direction steel plate and a steel structure section longitudinal-bridge-direction steel plate; the pressure resistance of concrete and the tensile strength of a steel structure can be fully exerted, the pier can be constructed in one stage, the concrete foundation can be firstly constructed, then the steel-concrete section can be constructed in stages, and the construction period is flexible and controllable.
本发明涉及一种钢混组合桥墩墩底结构及其施工方法，包括承台、混凝土段、钢混段及钢结构段，混凝土段为预埋墩柱混凝土，预埋墩柱混凝土通过预埋墩柱混凝土竖筋、预埋墩柱混凝土顺桥向箍筋及预埋墩柱混凝土横桥向箍筋与承台相连；预埋墩柱混凝土具有定位钢板，定位钢板包括分别位于预埋墩柱混凝土上下部位的上定位钢板及下定位钢板，竖向钢筋通过上定位钢板及下定位钢板进行安装定位；钢混段具有钢混段横桥向钢板和钢混段顺桥向钢板，钢结构段具有钢结构段横桥向钢板和钢结构段顺桥向钢板；能充分发挥混凝土抗压及钢结构抗拉性能，桥墩可在一个阶段施工完成，也可先施工混凝土基础，再施工钢混段分阶段施工，施工工期灵活可控。
