Construction Technology for Adding Bent Cap to Existing Column Piers

摘要:

既有柱式墩增设盖梁施工技术是在墩顶增设盖梁位置植入螺杆并安装钢盖梁，然后在钢盖梁上安装支座，并通过PLC同步顶升系统将桥梁梁体从原支座受力体系转移至新支座受力体系上。经过对既有柱式墩增设盖梁的处理后大大提高了桥梁的抗倾覆能力，改善了桥梁的受力状况。其相关技术参数可供同行参考。

Abstract:

The construction technology for adding bent cap to existing column piers is to implant screw rods at the position where the bent cap is added on the pier top and install a steel bent cap, and then install the bearings on the steel bent cap. And the bridge girders are transferred from the original bearing force system to the new bearing force system through the PLC synchronous jacking system. After the treatment of adding bent cap to the existing column piers, the anti-overturning ability of the bridge is greatly improved, and the stress condition of the bridge is improved. The relevant technical parameters can be used as a reference for peers.
