Prefabricated pier column and bearing platform connecting structure provided with pier bases and construction method thereof
The invention discloses a prefabricated pier column and bearing platform connecting structure provided with pier bases and a construction method thereof. The connecting structure is characterized in that pier base structures are arranged at the positions, corresponding to pier columns, of a bearing platform, grouting sleeves connected with vertical main reinforcements of the pier columns are buried in pier bases, the grouting sleeves keep away from plastic hinge areas, the main reinforcements of the prefabricated pier columns extend out of the column bottoms during prefabrication and are inserted into sleeves in the pier bases during hoisting, and then high-strength cement paste is injected into the sleeves in a pressed mode to achieve firm connection. The connecting structure has the characteristics of being simple, convenient to construct and beneficial to guaranteeing the connecting quality of the grouting sleeve.
本发明公开了一种设置墩座的预制桥墩柱与承台连接构造及其施工方法，其特征在于承台对应安装墩柱的地方设置墩座构造，连接墩柱竖向主钢筋的灌浆套筒埋在墩座内，使得灌浆套筒避开塑性铰区，预制桥墩柱预制时其主钢筋伸出柱底，吊装时插入墩座中的套筒内，再在套筒内压注高强水泥浆，实现牢固连接。具有连接构造简单、施工方便、有利于保障灌浆套筒连接质量的特点。
