The invention provides a hollow prefabricated assembled pier adopting a grouting sleeve, and the pier comprises a pier body with a through pouring hole, wherein the grouting sleeve is embedded in the lower surface of the pier body, the grouting sleeve is circularly arranged around the pouring hole, a U-shaped steel bar is inversely arranged in a bearing platform main body, and the U-shaped end of the U-shaped steel bar extends out of the upper surface of the bearing platform for a certain length, and the length can be adjusted according to needs; the embedded part is provided with a plurality of pier main ribs evenly distributed in the bearing platform body, and the top of each pier main rib is provided with a connecting part extending out of the upper surface of the bearing platform body. The invention further discloses a connecting method of the hollow prefabricated assembled bridge pier adopting the grouting sleeve. According to the prefabricated pier with the pouring holes, the stress performance is fully guaranteed, the anti-seismic performance of the pier body is improved, and the innate problems that a hollow pier is poor in bending resistance and shearing resistance are solved.
本发明提供了一种采用灌浆套筒的空心预制拼装桥墩，包括：具有贯穿浇灌孔的墩身，灌浆套筒内嵌于墩身的下表面，灌浆套筒圆形布设于浇灌孔四周，U型钢筋倒置于承台主体内，且U型钢筋的U型端位置从承台的上表面伸出一定的长度，其长度可以根据需求进行调节，预埋件具有若干均布于承台主体内的桥墩主筋，桥墩主筋的顶部具有伸出承台主体上表面的连接部。本发明还公开了一种采用灌浆套筒的空心预制拼装桥墩的连接方法。本发明的具有浇灌孔的预制桥墩不但充分保证了受力性能，提高了墩身的抗震性能，克服了空心桥墩抗弯能力弱，抗剪能力差的先天问题。
