Method for determining side boundary of passenger dedicated line contact net pillar

Abstract

The invention provides a method for determining the side boundary of a passenger dedicated line contact net pillar. The method includes the first step of obtaining parameters of all first-level control net CPIs and second-level control net CPIIs along a passenger dedicated line, as well as line parameters of the passenger dedicated line; the second step of using an RTK device to collect coordinates of each first-level control net CPI and coordinates of each second-level control net CPI, and performing single-point checkout to ensure data determinacy, measuring coordinates of each contact net pillar basic center, and calculating starting point and end point coordinates of a curve and intersection point coordinates; the third step of importing the line parameters of the passenger dedicated line and the measured coordinates of each contact net pillar basic center, and drawing a line center and basic center relative position diagram to measure the side boundary of the passenger dedicated line contact net pillar through terrain and cadastre mapping software. The problems of slow construction, long construction periods, many measurement workers and low measurement precision and the likeduring the measurement of the side boundary of the passenger dedicated line contact net pillar in the prior art are solved.

Description

Technical field [0001] The invention relates to a method for determining the side boundary of a catenary pillar in the construction of an electrified railway passenger dedicated line. Background technique [0002] In the professional construction of the catenary of electrified railways, due to the impact of the construction period in front of the station and the short construction period of the catenary, the installation of the catenary arm is usually carried out without the railway track being laid and the CP III results have not been produced. The traditional measurement method of the side boundary of the catenary pillar: mainly uses a total station to set out coordinates. Due to the large number of on-site cross-constructions, more vehicles, slow construction, long construction period, and more measurement personnel required, the accuracy of data collection is not high and cannot meet the requirements of the construction period. Summary of the invention [0003] The invention ...
