Large-diameter pile foundation reinforcement cage centering device
A large-diameter pile foundation reinforcement cage centering device comprises a thickened steel casing, a reinforcement cage, a fender pile system and a centering system, four fender piles are arranged on the ground around a pile hole and connected through a pull rope, a pull rope tensioning device is arranged on the pull rope, a GPS receiver is installed on the top face of a bracket, and a laser transmitter and a video monitoring system are installed on the bottom face of the bracket. By the adoption of the device, the potential safety hazard existing in a large-diameter pile foundation handheld plumb bob can be effectively solved, pedal erecting is omitted, and the safety of a large-diameter pile foundation handheld plumb bob is improved. Through primary centering and secondary precise centering, the automation degree of centering of the pile foundation reinforcement cage is improved, meanwhile, the centering precision is further improved, and popularization is facilitated.
一种大直径桩基础钢筋笼对中装置，包括加厚钢护筒、钢筋笼、护桩系统和对中系统，在桩孔四周地面上设置四根护桩，护桩通过拉绳连接，在拉绳上设置拉绳拉紧装置，托架顶面安装GPS接收器，托架底面安装激光发射器和装视频监控系统，在钢筋笼顶部沿着竖向钢筋方向垂直焊接校核钢筋，校核钢筋交叉点安装激光接收器，环形钢筋固定环底面与上坐标调整支撑杆连接，采用上述装置，能够有效解决大直径桩基础手持吊线锤存在安全隐患并省去踏板架设，通过初次对中、二次精确对中，不仅提高了桩基础钢筋笼对中自动化程度，同时进一步提升对中精度，有利于推广。
