Steel wire rope circumferential prestress construction method
The invention discloses a steel wire rope circumferential prestress construction method which comprises the following steps: step 1, selecting the upper end and the lower end of a reinforced pier as lofting positions of a connecting device; step 2, cleaning the lofting position and the bonding surface of the connecting device, and brushing a binder on the lofting position and the bonding surface of the connecting device; step 3, bonding a connecting device: bonding the connecting device to the lofting position; step 4, mounting a steel wire rope and a first anchorage device which are annularly arranged; 5, installing a spirally arranged steel wire rope and a second anchorage device; and sixthly, tensioning and anchoring are conducted. According to the steel wire rope circumferential prestress construction method, the problem of repairing and reinforcing vertical cracking of the bridge pier is solved.
本发明公开了一种钢丝绳环向预应力施工工法，步骤一，选定被加固桥墩的上下两端为连接装置的放样位置；步骤二，对放样位置进和连接装置的粘结面进行清理，并涂刷粘结剂；步骤三，粘结连接装置：将连接装置粘结到放样位置；步骤四，安装环向布置钢丝绳及第一锚具；步骤五，安装螺旋布置钢丝绳及第二锚具；步骤六，张拉锚固。本发明的钢丝绳环向预应力施工工法解决了桥墩竖向开裂修复加固问题。
