Numerical control method for segmental prefabricated bridge erection line shape
The invention discloses a numerical control method for the segmental prefabricated bridge erection line shape, and the method comprises the following steps: measuring the actual measurement point position of an erected segmental beam, comparing the actual measurement point position with the theoretical measurement point coordinate, and obtaining the erection deviation of the segmental beam; constructing a translation matrix and a rotation matrix according to the erection deviation, performing spatial movement on the theoretical measurement point coordinates of all the unerected segmental beamsaccording to the translation matrix and the rotation matrix, performing linear fitting to obtain the prediction deviation of the last segmental beam, and according to the prediction deviation, considering whether subsequent unerected segmental beams continue to be normally erected or not or taking deviation rectifying measures. According to the method, the line shape of bridge prefabricated segmental erection construction is predicted, so that the erection construction error is within a controllable range, closure construction is smoothly completed, and engineering loss caused by the fact that the erection line shape is not corrected in time is avoided.
本发明公开了一种关于节段预制桥梁架设线形的数控方法，包括以下步骤：测得架设完成后的节段梁的实际测点位置，将其与其理论测点坐标进行对比，得出该节段梁的架设偏差；根据所述架设偏差构建平移矩阵和旋转矩阵，将所有未架设节段梁的理论测点坐标都按照所述平移矩阵和所述旋转矩阵进行空间移动，并进行线形拟合，得出最后一个节段梁的预测偏差，根据该预测偏差，考虑后续未架设节段梁是否继续进行正常架设或采取纠偏措施。本发明对桥梁预制节段架设施工的线形预测，使架设施工误差处于可控范围，顺利完成合龙施工，避免由于架设线形未及时纠正导致的工程损失。
