Double-block type ballastless track measurement rechecking detection ruler and measurement rechecking detection method
The invention relates to the technical field of ballastless track construction and especially relates to a double-block type ballastless track measurement rechecking detection ruler and a measurementrechecking detection method. The method is characterized by using a total station for building a station, measuring prism target points or prism-free target points, measuring coordinates of the two prism target points or coordinates of the two prism-free target points, and according to the coordinates of the target points, reversely calculating a line mileage of the target points; according to thereversely calculated line mileage, reversely calculating designed rail surface elevations of centers of top surfaces of left and right steel rails of a track where the detection ruler is placed and atransverse offset distance relative to a line center line; depending on actual measured point coordinates, reversely calculating the transverse offset distance of the actual measurement point relative to the line center line and a height difference relative to the design elevations of the top surfaces of the left and right steel rails; and correcting the transverse offset distance and the designelevations, and acquiring the transverse deviation and the elevation deviation of the left and right steel rails relative to a designed line. The detection ruler and the detection method have advantages that a calculation speed is high, calculation precision is high, and measurement errors caused by improper use of a rail inspection trolley can be avoided through rechecking.
本发明涉及无砟轨道施工技术领域，具体来说是一种双块式无砟轨道测量复核检测尺及测量复核检测方法，利用全站仪建站，测量棱镜目标点或无棱镜目标点，测量出两个棱镜目标点坐标或两个无棱镜目标点坐标，根据目标点坐标，反算出目标点处的线路里程；根据反算的线路里程，反算出检测尺放置处的轨道左、右股钢轨顶面中心的设计轨面高程和相对于线路中线的横向偏距；根据实测点坐标，反算出实测点相对于线路中线的横向偏距和相对于左右股钢轨顶面设计高程的高差，并对横向偏距和设计高差进行修正，得出实际的左右股钢轨相对于设计线路的横向偏差和高程偏差，其优点在于：计算速度快，计算精度高，通过复核可避免因轨检小车使用不当造成的测量错误。
