Bridge anchor pipe positioning method
The invention provides a bridge anchor pipe positioning method, which comprises the following steps of: establishing a bridge arch axis model by using modeling software, measuring a semi-finished product arch section and an anchor pipe, establishing a measurement model of an actually measured central axis of the arch section and the anchor pipe, and substituting the measurement model into the bridge arch axis model; and calculating an error value between the actually measured central axis of the anchor pipe and the designed central axis of the suspender or the designed central axis of the anchor pipe, and adjusting the position of the anchor pipe on the semi-finished arch section according to the error value, thereby realizing the positioning of the anchor pipe. The installation precision, accuracy and stability of the anchor pipe can be improved.
本发明提供一种桥梁锚管定位方法，通过使用建模软件建立桥梁拱轴线模型，测量半成品拱节段及锚管并建立拱节段及锚管实测中心轴线的测量模型，将测量模型带入桥梁拱轴线模型，计算锚管的实测中心轴线与吊杆的设计中心轴线或锚管的设计中心轴线的误差值并以此对半成品拱节段上的锚管位置进行调整，从而实现了锚管的定位。其能够提高锚管安装的精度、准度和稳定性。
