Shear nail-double steel pipe fabricated pier and construction method thereof
The invention provides a shear nail-double steel pipe high-strength assembly type pier and a construction method thereof. The assembly type pier comprises a prefabricated concrete pier column, and the bottom of the prefabricated concrete pier column is welded to a circular slotted steel pipe through a connecting steel plate; the concrete bearing platform is located at the bottommost part of the fabricated pier; and the prefabricated concrete pier column and the concrete bearing platform are fixedly connected through the high-strength connecting section. The round steel pipe at the bottom of the prefabricated concrete pier column and the shear nails of the steel jacket box at the top of the concrete bearing platform are rapidly positioned and fixed, the advantage of self-stabilization of the assembly sections is achieved, the problem that complex supports need to be arranged for installation of an existing assembly type pier column and the concrete bearing platform is solved, the construction process is greatly simplified, and the construction efficiency is improved. And the problems that concrete construction of a connecting section in an existing fabricated bridge pier is complex, and dense pouring cannot be achieved are solved, the high strength of the fabricated connecting section is guaranteed, and reliability and safety are enhanced.
本发明提出了一种剪力钉‑双钢管高强装配式桥墩及其施工方法，装配式桥墩包括预制混凝土墩柱，底部通过连接钢板与圆形开缝钢管焊接；混凝土承台，位于装配式桥墩最底部；高强连接段，预制混凝土墩柱和混凝土承台通过高强连接段进行固定连接。本发明将预制混凝土墩柱底部的圆钢管和混凝土承台顶部钢套箱的剪力钉进行快速定位固定，具有拼装节段自稳定的优势，不仅解决了现有装配式墩柱与混凝土承台安装需要设置复杂支撑的问题，大大简化了施工过程，而且解决了现有装配式桥墩中连接段混凝土施工复杂、无法浇筑密实的问题，保障了装配连接段的高强度，增强了可靠性和安全性。
