The invention relates to an ultra-high-speed low-vacuum pipeline maglev traffic system module precast slab fine adjustment method. The method comprises the steps that the length of a prism bar is determined; the sleeve mileage is the same as the middle pile mileage of the center line, and then three-dimensional coordinates of a center point of a sleeve supporting face and coordinates of a middle pile point are calculated; calculating the direction from the center point of the sleeve supporting surface to the center pile point, and further calculating prism plane coordinates; measuring the actual three-dimensional coordinates of the prism by using a total station, and calculating the deviation of the prism; calculating the adjustment amount of the prism deviation in the longitudinal direction, the transverse direction and the vertical direction; and judging whether the deviation after projection meets the tolerance requirement, if so, stopping the fine adjustment of the prism, and otherwise, guiding the fine adjustment of the module prefabricated slab according to the deviation after projection. According to the method, the theoretical three-dimensional coordinates of the prism can be calculated by using line design parameters according to the three-dimensional coordinates of the center point of the sleeve supporting surface, the offset is calculated by measuring the actual prism coordinates, and then the adjustment amounts in the longitudinal direction, the transverse direction and the vertical direction are calculated so as to guide the fine adjustment of the module prefabricated slab.

    本发明涉及一种超高速低真空管道磁浮交通系统模组预制板精调方法,确定棱镜杆长度;计算套筒里程,套筒里程与中线中桩里程相同,进而计算套筒支撑面中心点三维坐标和中桩点坐标;计算套筒支撑面中心点到中桩点的方向,进而计算棱镜平面坐标;使用全站仪测量棱镜实际三维坐标,计算棱镜偏差;计算棱镜偏差在纵、横、竖三个方向的调整量;判断投影后偏差是否满足限差要求,满足则停止本棱镜精调,否则根据投影后偏差指导模组预制板精调。本发明能够根据套筒支撑面中心点的三维坐标,利用线路设计参数计算棱镜理论三维坐标,通过测量实际棱镜坐标计算偏移量,然后计算纵、横、竖三个方向的调整量,以此指导模组预制板精调。
