Semi-fabricated pier and construction method thereof
The invention relates to a semi-fabricated bridge pier. A lower-section bridge pier is formed by fixing a self-locking grouting pipe at the top of a reinforcing steel bar of a lower-section bridge pier reinforcement cage and then pouring lower-section bridge pier concrete; the bottom of a reinforcing steel bar of an upper-section bridge pier reinforcement cage of the upper-section bridge pier is inserted into a self-locking grouting pipe on the upper surface of the lower-section bridge pier concrete, grouting is conducted on the self-locking grouting pipe, and the upper-section bridge pier is formed by pouring the upper-section bridge pier concrete into the upper-section bridge pier reinforcement cage after grouting and fixing; the lower segment pier reinforcement cage and the upper segment pier reinforcement cage are both bound on the ground and then integrally hoisted, and a semi-assembly mode is achieved. The upper and lower segment pier reinforcement cages are both bound on the ground and then integrally hoisted, semi-assembly of pier construction is achieved, the reinforcement cage integral hoisting technology enables lower segment concrete pouring and upper segment reinforcement cage binding to be carried out at the same time, the construction working face is increased, the construction period is shortened, and the construction efficiency is improved. The operation of connecting the steel bars between the bridge pier sections through the self-locking grouting pipe is simple, and the quality is reliable.
本发明涉及一种半装配式桥墩，下节段桥墩通过在下节段桥墩钢筋笼的钢筋顶部固定自锁式灌浆管后浇筑下节段桥墩混凝土形成；上节段桥墩的上节段桥墩钢筋笼的钢筋底部插入下节段桥墩混凝土上表面的自锁式灌浆管中，并对自锁式灌浆管进行灌浆，上节段桥墩由灌浆固定后的上节段桥墩钢筋笼浇筑上节段桥墩混凝土形成；下节段桥墩钢筋笼与上节段桥墩钢筋笼均在地面绑扎后整体吊装，实现半装配式。本发明中的上下节段桥墩钢筋笼均在地面绑扎后整体吊装，实现了桥墩施工的半装配式，钢筋笼整体吊装工艺使得下节段混凝土浇筑与上节段钢筋笼绑扎可同时进行，增加了施工作业面，缩短了施工工期，通过自锁式灌浆管实现桥墩节段间钢筋连接的操作简单、质量可靠。
