In October 2024, Panxing Railway, a precision measurement company, officially started the data collection work from the Dazhanggu Tunnel to the Jinzhou Tunnel, and the measurement work officially kicked off.
Safety training
The new Panxing Railway has a total length of 98.314 kilometers and is located in Guizhou Province. The line leads from the Shanghai-Kunming passenger special Panzhou Station, through Panzhou Shiqiao Town, Xiangshui Town, Baotian Town, Xingyi Qingshui River to Wanfenglin Airport to set up Xingyi South Station. There are 2 new stations (Baotian Station and Xingyi South Station) and 1 line station (Pingjing Line Road Station), and 1 reconstructed station (Panzhou Station). The total length of the main line bridges and tunnels is 88.91 kilometers, accounting for 90.44% of the line length (including 45 bridges of 20.571 kilometers, accounting for 20.92% of the line length; There are 38 tunnels with a total of 68.339 kilometers, accounting for 69.51% of the length of the line), and the precision measurement company undertakes a total of 125.726 kilometers of long-orbit data collection tasks.
Line surveys
In order to ensure the smooth development of the surveying work, the surveyors have made a lot of preparations in the early stage. First of all, arrange the instruments and equipment to enter the site as soon as possible, and calibrate the instruments and equipment in time to ensure the accuracy of the data. Secondly, the personnel are trained in safety and technical disclosure to ensure the safe development of various measurement work on site, and the line investigation of the front line is carried out in advance before the measurement to ensure the smooth operation of the measurement task. As of today, the first pass of inertial navigation data acquisition is 16.315 km, and the second pass is 6.945 km.
Technical disclosure
Looking forward to the future, the precision measurement company will complete the future challenges with more enthusiasm and firm faith, play a huge role in the construction of Panxing Railway, and contribute to the railway industry of the motherland. (Correspondent: Zhang Xiaolong)
