Reinforcing steel bar sleeve connecting structure, segmental prefabricated assembled pier and construction method
The invention provides a reinforcing steel bar sleeve connecting structure, a segmental prefabricated assembled pier and a construction method. The reinforcing steel bar sleeve connecting structure comprises a foundation, a bottom segment, a bottom joint reinforcing steel bar sleeve, a foundation reserved hole channel, a bottom segment reinforcing steel bar sleeve and the like. When the foundation is constructed, bottom joint steel bar sleeves or reserved hole channels are pre-buried in the positions corresponding to the steel bars, bottom section steel bar sleeves are pre-buried in the positions corresponding to the steel bars when the bottom section is prefabricated, and when the bottom section is spliced with the foundation, the bottom joint steel bar sleeves are sleeved with the bottom section steel bar sleeves one by one, or the bottom section steel bar sleeves penetrate into the reserved hole channels of the foundation one by one. And a reinforcing steel bar penetrates into the bottom section reinforcing steel bar sleeve and the bottom joint reinforcing steel bar sleeve or the reserved hole channel, and a grouting material is injected in a pressing mode to form the reinforcing steel bar sleeve connecting structure. According to the connecting structure, the stress of the bottom joint and the bottom section is remarkably improved, so that the bottom joint and the bottom section are matched with each other in structural arrangement and stress requirements, and the connecting structure can meet the anti-seismic requirements of medium-high seismic areas; and the reinforcing steel bar sleeve connecting structure can adapt to non-matched installation between the prefabricated segment and the foundation, is low in cost and meets the engineering application requirement.
本发明提供一种钢筋套管连接结构、节段预制拼装式桥墩及施工方法，钢筋套管连接结构包括基础、底节段、底接缝钢筋套管、基础预留孔道、底节段钢筋套管等。基础施工时在对应钢筋位置预埋底接缝钢筋套管或预留孔道，底节段预制时在对应钢筋位置预埋底节段钢筋套管，底节段与基础拼接时，将底节段钢筋套管一一套在底接缝钢筋套管上，或将其一一穿入基础预留孔道，将钢筋穿入底节段钢筋套管和底接缝钢筋套管或预留孔道中，再压注灌浆料形成钢筋套管连接结构。本连接结构显著提高底接缝和底节段的受力，使底接缝和底节段构造设置和受力需求相互匹配，可适用于中高震区抗震需求；可适应预制节段和基础间的非匹配安装，且成本低，满足工程应用需要。
