Problems solved by technology

At present, the measurement of catenary and rail of rail transit mostly adopts the method of coordinating measurement with level instrument and total station. Its shortcomings are that the measurement accuracy is not high, the operation is cumbersome, the data of each stakeout point is relatively independent, and it is not easy to correct and adjust immediately after an error occurs.

Embodiment Construction

[0034] The method for measuring rail transit catenary and rail based on the track foundation pile control network of the present invention includes the steps of on-site pile delivery, office calculation, center line measurement and leveling survey, stakeout piling, and office arrangement; the center line measurement step includes the following steps: The above steps:

[0035] The first step is to carry out pile crossing according to the route design drawings; the pile crossing data include: straight lines and curves, permanent benchmark points and additional temporary benchmark points, middle pile odometer, unified odometer, unified mileage and construction mileage comparison table, slope table and benchmarking point table, coordinates of wire point piles provided by the design and their position distribution table;

[0036] The second step is to use the coordinate stakeout method to measure the center line:

[0037] (1), such as figure 1 As shown, according to the line desi...

Abstract

The invention discloses a rail traffic catenary system and conductor rail measuring method based on a rail foundation pile control network. The method includes on-site pile delivery, calculation of interior work, center line measurement and level measurement, setting out and piling and settlement of interior work. The center line measurement includes 1, delivering the piles according to a route design drawing; 2, measuring the center line by a coordinate setting-out method; and 3, measuring level. Pile delivery documents include rectilinear and curvilinear permanent and added temporary bench marks, a king-pile mileage chart, a uniform mileage chart, a uniform mileage and construction mileage comparison chart, a slope chart and a leveling point chart, and guide line pile coordinates provided by design and a position distribution chart thereof. The rail traffic catenary system and conductor rail measuring method has the advantages that rail-less measurement is realized, technical support for accurate measurement is provided, and accuracy of hanger mounting and adjusting is improved greatly.

Description

technical field [0001] The invention relates to a method for measuring a rail transit catenary and a rail, in particular to a method for measuring a rail transit catenary and a rail based on a rail foundation pile control network. Background technique [0002] The use of catenary trackless measurement can effectively solve the negative impact caused by the project's possible restriction of other professional projects and speed up the construction of railways. Therefore, the accuracy requirements for rail transit catenary and rail measurement are very high. At present, the measurement of the catenary and rail of rail transit is mostly carried out by the level instrument and the total station. The disadvantages are that the measurement accuracy is not high, the operation is cumbersome, the data of each stakeout point is relatively independent, and it is not easy to correct and adjust immediately after an error occurs. Contents of the invention [0003] The purpose of the in...
