The preliminary test of Xuhe Railway (Xuzhou Section) successfully passed the acceptance
Recently, the preliminary test of the Xuhe Railway (Xuzhou Section) designed by China Railway Design Jinan Institute successfully passed the acceptance.
Xuzhou-Heze Railway (Xuzhou Section) is located in the northwest of Xuzhou City, the line is in a north-south direction, leading from Shatang Station of Longhai Railway, using the existing Xupei Railway and Fengpei Railway to rebuild, from Fengpei Railway Shouxian Station to the west to the Sulu provincial boundary, connecting to the planning Xuhe Railway (Heze Section), forming an auxiliary channel for the southward transportation of western coal. The total length of the main line is 109.268km. The line connects the Beijing-Kowloon Railway in the west and the Longhai Railway in the east, forming a convenient connection line between Xuzhou and Heze.
The project has a long line, a large topographic surveying and mapping workload, and a tight construction period, so it is a big challenge for the surveying and mapping profession to complete all the surveying and mapping work efficiently within the construction period requirements with quality and quantity. The Party branch of surveying and mapping gives full play to the advanced nature of party members, mobilizes the power of young people, actively innovates, adopts the offline control network layout and terrain flight work to carry out the way simultaneously, and the surface elevation is temporarily processed by WGS84 height, and the parameters are converted to the correct benchmark in the later stage, which provides a guarantee for the smooth development of the follow-up work. During the implementation of the project, the Longhai railway is a V-shaped skylight, up and down the line is measured separately, and the existing line mileage measurement is carried out using the GNSS-RTK method, which not only greatly improves the speed and accuracy of the measurement, but also reduces the labor cost, and at the same time, the layout of the measurement and control network is also carried out synchronously, and the field work is in an orderly manner, which shortens the initial measurement time and improves the efficiency of the survey.
