Ballast-installation and track-regulation measurement quick positioning method for ballast track engineering

Abstract

The invention relates to a ballast-installation and track-regulation measurement quick positioning method for ballast track engineering. The ballast-installation and track-regulation measurement quick positioning method for the ballast track engineering is characterized by comprising the following steps of: measuring the center of a prism on a small track car to obtain a three-dimensional coordinate of the center of the prism by utilizing the resection or the direction positioning stationing of a total station; converting out the central position of the prism and the central position of a steel track at the corresponding mileage position through the geometrical parameter of the small track car; connecting a personal digital assistant (PDA) measurement handbook with the total station to realize real-time communication; transmitting actual measurement three-dimensional coordinate data of the total station to the measurement handbook in real time; quickly working out the measured position and design data of centers of steel tracks at the measured position and the mileage position through measurement software; calculating and displaying difference between track lifting volume and track lining volume; and guiding the track-regulation operation of large mechanized road maintenance equipment. According to the ballast-installation and track-regulation measurement quick positioning method for the ballast track engineering, a traditional measurement positioning method is changed, and therefore, complicated measurement steps and measurement errors are reduced, field measurement positioning is convenient and quick, and the measurement efficiency is improved. The ballast-installation and track-regulation measurement quick positioning method for the ballast track engineering has the characteristics that personnel allocation is few, equipment supplies are few, and the work efficiency is high.

Description

technical field [0001] The invention relates to a train track construction project, in particular to a rapid positioning method for ballasting the entire track measurement in a ballasted track project. Background technique [0002] With the progress and development of society, the construction of "four horizontal and four vertical" high-speed railways has basically taken shape, and the use of ballasted tracks has gradually increased. In order to make the straight section of the line straight and the curved section smooth, the train has high safety and ride comfort when running. After the track is laid, the smoothness of the track must be adjusted to meet the national railway regulations and various acceptance standards. The ballasting track construction of the ballasted track railway usually uses the conductor control network and the total station to carry out static track measurement, and the large-scale mechanized track maintenance equipment (abbreviation: large-scale mach...

AI Technical Summary

Problems solved by technology

[0008] It can be seen that the traditional method is used to measure and locate the whole track of ballasting, and the work efficiency of measurement and positioning is restricted due to many steps.
