Problems solved by technology

In the curved section, due to the different projections of the centerline of the track on each plane, the positioning error of the boss is often caused
At the same time, due to the mutual influence of the elevation and the plane position, if any error occurs in any link, it is necessary to repeat the measurement and lofting work, and the construction efficiency is low

Abstract

The invention discloses a construction measurement method of a plate type convex barricade with an unballasted track. The method comprises the following steps of: fixedly installing a small prism on an installed convex barricade template; arranging a total station at the center line of a track line and freely stationing based on a foundation pile control net; lofting by a small prism installed on a total station measurement template by using a polar coordinate method and transmitting the measurement data to an operational computer via a wireless module; comparing the returned measurement data with the theoretical design value which is input to the operational computer in advance, and computing the deviation between the actual position and the design position by construction measurement software of the convex barricade; and adjusting the position of the convex barricade template based on the adjustment value shown on the computer. By freely stationing the polar coordinates for lofting the convex barricade template, the method can realize the planar and elevational lofting and has the advantages of high measurement precision and high efficiency.

Description

technical field [0001] The invention relates to a construction measurement method for a convex abutment of a ballastless track, in particular to a construction measurement method for a convex abutment of a CRTS I-type ballastless track. Background technique [0002] With the advent of high-speed railway construction in my country, the traditional ballasted track has reached the limit of its carrying capacity under the long-term load of high-speed trains, the smoothness of the track has deteriorated, the maintenance workload has increased, and the available maintenance time has become increasingly This seriously hinders the development of high-speed railways. [0003] At present, ballastless tracks are basically used in domestic railway passenger dedicated lines, and there are two main types of ballastless tracks: double-block ballastless track and slab ballastless track. Slab ballastless track is mainly classified into CRTS I type slab ballastless track, CRTS II slab ballast...
