The invention discloses an all-parameter trackless measurement construction method for a subway catenary, and relates to the technical field of metro construction. The method comprises the steps: S1, obtaining the coordinates of suspension points through the mileages of the suspension points and the distances of the suspension points deviating from the center of a pantograph; S2, conducting surveying, lofting and re-checking, namely importing the coordinates of the suspension points into a total station, setting up the total station by using a CPIII control pile, lofting and marking the suspension points point by point, recording the elevation h of the corresponding suspension points after lofting, and obtaining a measurement angle alpha; and S3, performing all-parameter calculation by adopting the elevation h of the suspension points and the measurement angle alpha to obtain the length of a davit, the installation correction angle of the davit, the production angle of the davit and the installation height of a cantilever on the davit. The method meets the high-precision requirement of a high-speed subway, and can be widely applied to subway catenary trackless measurement construction.

    本发明公开了一种地铁接触网全参数无轨测量施工方法,涉及地铁施工技术领域,包括:S1,通过悬挂点的里程、悬挂点偏离受电弓中心的距离得到悬挂点的坐标;S2,测量放样及复核:将悬挂点的坐标导入全站仪,利用CPIII控制桩进行全站仪设站,对悬挂点逐点放样标记,放样后记录对应的悬挂点高程h,并得到测量角度α;S3,采用悬挂点高程h和测量角度α进行全参数计算,得到吊柱长度、吊柱安装整正角度、吊柱生产角度、悬臂在吊柱上的安装高度。本发明满足高速地铁高精度要求,可广泛运用于地铁接触网无轨测量施工。
