Prefabricated pier with spiral stirrups and construction method thereof
The invention discloses a prefabricated pier with spiral stirrups and a construction method of the prefabricated pier. The prefabricated pier comprises a pier body, and a bent cap and a bearing platform are arranged at the upper end and the lower end of the pier body respectively. The construction method comprises the following steps of: fixing longitudinal main reinforcements and connecting components on a steel reinforcement jig frame, arranging a machine to fix the outlet positions of the spiral stirrups, fixing the end parts of the spiral stirrups on the longitudinal main reinforcements, rotating the steel reinforcement jig frame, and uniformly and horizontally moving to finish the arrangement of the spiral stirrups; supplementing reinforcing stirrups to the longitudinal main reinforcements, and completing the manufacturing of a reinforcement cage; placing the reinforcement cage in the formwork to be poured to form a pier body, and transporting the pier body to the site to be hoisted and installed after maintenance. The number of the spiral stirrups is reduced, so that in the prefabricating process of the pier body, the occupied time for binding and fixing the spiral stirrups is reduced, and the production efficiency of the prefabricated pier body is improved.
本发明公开了一种螺旋配箍筋的预制桥墩及其施工方法，该预制桥墩包括桥墩主体，所述桥墩主体的上下端分别设置有盖梁和承台。该施工方法包括在钢筋胎架上固定纵向主筋以及连接构件，设置机器固定螺旋箍筋出口位置，将螺旋箍筋的端部固定在纵向主筋上，转动钢筋胎架并均匀水平移动，完成螺旋箍筋的布置；在纵向主筋上补充加强箍筋，完成钢筋笼制作；将钢筋笼放在模板中浇筑，形成桥墩主体，养护期后运至现场吊装安装。本发明螺旋箍筋数量减少，因此，在桥墩主体预制过程中，绑扎和固定螺旋箍筋的时间占用减少，从而提高了预制桥墩主体的生产效率。
