Frame bridge jacking construction method and construction system thereof
The invention relates to a frame bridge jacking construction method and a construction system thereof, and relates to the field of frame bridge construction. According to the method, the GPS coordinate is used as the reference of the position, and the initial coordinate of the first prism capable of reflecting the position of the frame bridge is recorded, so that the actual coordinate of the firstprism can be accurately calculated in combination with the measurement data of the total station after each jacking is finished. And the actual jacking distance of the frame bridge is obtained through comparison with the initial coordinate, so that the design coordinate which is more suitable for the actual situation can be obtained to be compared with the actual coordinate, the measurement erroris small, the selection of comparison data is more reasonable, the generated error is smaller, and the automation degree of the measurement work is high.
本申请涉及一种框架桥顶进的施工方法及其施工系统，涉及框架桥施工的领域。利用GPS坐标作为位置的参考基准，并记录能够反应框架桥位置的第一棱镜的初始坐标，使得在每次顶进结束后，结合全站仪的测量数据，就可以精准计算出第一棱镜的实际坐标。再通过和初始坐标的对比，获取框架桥的实际的顶进距离，从而能够获得更贴合实际情况的设计坐标来和实际坐标进行对比，测量误差小，对比数据的选取更合理，产生的误差也就更小，并且测量工作的自动化程度高。
