When measuring, one person needs to hold a strong flashlight next to each CPIII point to illuminate the prism on the CPIII point. Since it is necessary to measure multiple points hundreds of meters away at the same time, each observation requires multiple people to hold a strong light Torch for lighting, measuring 12 points at a time, requires 12 person-times to light the special prism at close range, which consumes human resources and is inefficient
At the same time, due to the requirements of the CPIII network shape, the orientation of each point is similar, and it is relatively close in the field of view of the total station. The special prisms and targets of each point are exactly the same during night measurement, and it is difficult for observers to distinguish different CPIII points. Easy to cause alignment and measurement errors

The invention relates to a reflecting type measuring target special for a high-speed railway, which comprises a body (1) and a connecting bayonet (2), wherein the connecting bayonet (2) is arranged on the inner ring of the body (1) and matched with a framework of a prism (5); the reflecting type measuring target special for a high-speed railway is characterized in that a reflecting pure-colored background and a reflecting sighting pattern (3) in another color are printed on the surface of the body (1) through reflecting materials. The target is not only suitable for measurement under good observation conditions, but also can be adapted to the measurement in the environments with insufficient illumination, such as nighttime and the like, the labor cost of high-speed railway measurement is lowered, and the measuring accuracy and efficiency are improved.
Description
technical field [0001] The invention relates to a special measuring target plate for reflective high-speed railways. Background technique [0002] The track reference network (CPIII network) in the high-speed railway is composed of several positioning reference points (CPIII points) arranged equidistantly along the track line. These track reference points are usually fixed on the wall or pile The three-dimensional measurement mark on the track is calibrated, which is the benchmark for ballastless track laying and operation and maintenance. When laying, it is necessary to measure the mutual positional relationship between the CPIII point and the measuring point of the track, so as to ensure that the spatial position of the track laying meets the design requirements and ensures its smoothness. During operation and maintenance, it is also necessary to regularly measure the mutual positional relationship between the CPIII point and the track measurement point, and adjust it in ...
