Construction method and positioning device for improving centering degree of cast-in-situ bored pile reinforcement cage
The invention discloses a construction method and a positioning device for improving the centering degree of a reinforcement cage of a cast-in-situ bored pile. The construction method and the positioning device are used for solving the problem that the reinforcement cage possibly deviates from the center of the pile in the lowering process of the reinforcement cage in a pile hole and the concrete pouring process. An annular air bag is fixedly installed on the outer side of the annular steel plate, the annular air bag is provided with an inflation port and a deflation port, an electromagnetic control valve is installed at the inflation port, the annular air bag controlled by the electromagnetic control valve is inflated through the air compressor, and the deflation port is provided with an electromagnetic control valve and extends to the ground through a deflation pipe and a cable; the annular framework is mechanically connected with lifting equipment through steel wire ropes. In the process of injecting concrete into a pile hole, the positioning device is used for locally centering and positioning the reinforcement cage, so that the position of the reinforcement cage is kept unchanged, and the problems of floating and horizontal displacement of the reinforcement cage possibly occurring in the concrete pouring process are solved.
本发明公开了一种提高钻孔灌注桩钢筋笼居中度的施工工法及定位装置，用于解决钢筋笼在桩孔中下放及混凝土浇筑过程中可能出现的钢筋笼与桩中心偏位的问题。在环形钢板的外侧固定安装环形气囊，该环形气囊具有充气口和放气口，该充气口处安装电磁控制阀，通过该空气压缩机向电磁控制阀控制的环形气囊充气，放气口安装电磁控制阀并通过放气管和电缆线延伸至地面处；环形骨架通过钢丝绳与提升设备机械连接。将桩孔中注入混凝土过程中，通过定位装置对钢筋笼局部的进行居中定位，使得钢筋笼的位置保持不变，解决了在浇筑混凝土的过程中钢筋笼可能发生的上浮和水平位移问题。
