The invention discloses a prefabricated bridge pier and cushion cap connecting and constructing method and belongs to the technical field of bridge engineering. The prefabricated bridge pier and cushion cap connecting and constructing method comprises the following steps: S1, at first, processing a connected stressed longitudinal bar: drilling a hole at certain position of a rebar splicing area toform a bolt hole, and reaming the bolt hole to form an oblong hole; S2, prefabricating a bridge pier at a precast yard: prefabricating the bridge pier with the processed stressed longitudinal bar, astirrup and a positioning bar, and reserving the rebar splicing area for the bridge pier; and S3, pouring a cushion cap: placing a cushion cap reinforcement cage, reserving the stressed longitudinal bar, adopting the same drilling and reaming treatment, connecting the processed stressed longitudinal bar of the bridge pier, enabling the orientations of oblong holes in the stressed longitudinal barto be consistent, and pouring concrete through shuttering. The prefabricated bridge pier and cushion cap connecting and constructing method can meet the strength, ductility deformation and energy dissipation requirements after connection of the bridge pier and the cushion cap at an earthquake region, is simple in technology and easy to construct and can remarkably increase the construction speed.
本发明公开了一种预制桥墩与承台的连接及施工方法，属于桥梁工程技术领域，该预制桥墩与承台的连接及施工方法，包括以下步骤：S1、先将被连接受力纵筋进行加工：在钢筋搭接区一定位置钻孔形成螺栓孔，对螺栓孔进行扩孔形成长圆孔，S2、预制场预制桥墩：利用加工后的受力纵筋、箍筋以及定位筋预制桥墩，桥墩预留钢筋搭接区，S3、浇筑承台：放置承台钢筋笼，并预留受力纵筋，采用同样钻孔扩孔处理，与桥墩采用加工后的受力纵筋连接，受力纵筋上长圆孔朝向一致，立模板浇筑混凝土。本发明中，该预制桥墩与承台的连接及施工方法，能够满足地震区桥墩与承台连接后的强度、延性变形和耗能要求，且工艺简单，易于施工，能显著提升施工速度。
