Bridge pier column construction steel bar dismantling method
The invention discloses a bridge pier column construction steel bar dismantling method, which adopts a clamp to clamp a steel bar, a rubber pad is placed in the clamp to ensure that the clamp can firmly clamp the steel bar, the front end of the steel bar is lifted and fixed by a lifting rope of a crane, the clamp is connected with a sleeve of a hydraulic jack, and a worker stands in a lifting basket lifted by the crane to operate an oil pump of the jack. After the jack pushes the clamp to drive the steel bar to move forwards to the maximum length of the jack sleeve and the fixed bolt is unscrewed, the clamp is manually moved backwards and the jack sleeve is contracted, so that the end part of the jack sleeve in a non-extension state can be tightly attached to the pier, and the clamp is tightly attached to the top end of the jack sleeve; and fixing on the steel bar, and repeating the steps until the steel bar is pulled out. When the technology is used for pulling out the steel bar, a small amount of workers can be used for aloft work, so that the construction risk is reduced.
本发明公开了一种桥梁墩柱施工钢棒拆除方法，本技术采取夹具夹住钢棒，在夹子夹中放入橡胶垫以保证夹子可以牢靠的夹住钢棒，钢棒前端由吊车吊绳吊起固定，夹具与液压千斤顶套筒相连，工人站在吊车吊起的吊篮中操作千斤顶油泵，使千斤顶套筒伸长，千斤顶推动夹具带动钢棒向前移动，向前移动到千斤顶套筒的最大长度后，拧松固定螺栓后，人工使夹具后移，收缩千斤顶套筒，让千斤顶套筒在未伸长状态下端部可以紧贴桥墩，夹具紧挨在千斤顶套筒顶端，并固定在钢棒上，重复以上步骤直到钢棒被拔出。使用本技术进行钢棒的拔除可以使用少量人工在高空作业，使施工危险性降低。
