Fabricated pier and construction method
The fabricated pier comprises a prefabricated pier body and a bearing platform, a step is arranged at the lower end of the prefabricated pier body, a connecting piece a is arranged on the step, a boss is arranged on the inner side of the step, a positioning sleeve is arranged in the middle of the boss, a connecting piece b corresponding to the connecting piece a is arranged on the upper surface of the bearing platform, and the connecting piece a and the connecting piece b are fixed through bolts. Grooves corresponding to the bosses are formed in the surface of the bearing platform, the grooves are located between the connecting pieces b, and positioning pin shafts corresponding to the positioning sleeves are arranged on the grooves. The positioning sleeve and the positioning pin shaft are matched with each other to achieve quick butt joint of the prefabricated pier and the bearing platform, then the connecting piece a and the connecting piece b are fixedly connected through the bolt, and post-pouring is conducted on the reserved space, so that the pier connecting reliability is improved, meanwhile, pre-compressive stress is generated on a concrete connecting interface, the sleeve grouting process is avoided, and the construction cost is reduced. And the cast-in-place workload after pier assembly is minimized, so that the construction efficiency is improved, and the construction period is shortened.
本发明公开了一种装配式桥墩，包括预制桥墩和承台，预制桥墩的下端开设有台阶，台阶上设置有连接件a，台阶的内侧具有凸台，凸台的中部开设有定位套筒，承台的上表面设置有与连接件a对应的连接件b，连接件a和连接件b之间通过螺栓固定，承台表面开设有与凸台对应的凹槽，且凹槽位于连接件b之间，凹槽上开设有与定位套筒对应的定位销轴，还公开了施工方法。通过定位套筒和定位销轴互相配合，实现预制桥墩和承台快速对接，再通过螺栓将连接件a和连接件b固定连接并对预留空间进行后浇，从而增加桥墩连接的可靠性，同时使混凝土连接界面产生预压应力，避免了套筒灌浆工艺，使桥墩拼装后现浇工作量最小化，进而提高施工效率，缩短工期。
