Improved track structure and construction method thereof

Abstract

The invention discloses an improved track structure and a construction method, and belongs to the technical field of track traffic. The improved track structure comprises a concrete track bed and a steel track, sleeper bolt holes are formed at the two sides of the steel track, and fasteners are installed in the sleeper bolt holes respectively. The track structure further comprises track bearing grooves corresponding to a left track and a right track respectively, a notch is formed in each track bearing groove, the steel track is embedded in the notches, the space between each notch and the steel track is filled with an in-groove damping material, the track bearing groove is installed and fastened through the corresponding sleeper bolt holes in the concrete track bed, and existing fasteners are removed from the sleeper bolt holes corresponding to the track bearing groove. the in-groove damping material comprises an under-track base plate, track adjusting assemblies and a macromolecule damping material, the under-track base plate is arranged under the steel track, the track adjusting assemblies are arranged at the two sides of the track web of the steel track and act on the side wall of the groove opening, and the macromolecule damping material is filled in the notches, so that the vibration and noise reduction effect of a track line can be improved. and a good stray current protection effect is achieved for the track.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to an improved rail structure and a construction method thereof. Background technique [0002] Urban rail transit can better solve traffic congestion and promote urban development, but with the increase of line operation time, many problems of rail lines have been exposed. [0003] Urban rail transit, especially subway tracks, mainly pass through densely populated areas and under important buildings. The vibration and noise generated by trains seriously affect the life and work of people along the line. Therefore, the control of vibration and noise on existing lines has become an operational On the other hand, the iron filings and oil stains produced by the rail grinding during the operation of the track line adhere to the fasteners, resulting in a decrease in the insulation resistance of the rail to the ground, and the stray current of the track corrodes the line. ...

AI Technical Summary

Problems solved by technology

[0003]Urban rail transit, especially the subway track, its lines mainly pass through densely populated areas and under important buildings. The vibration and noise generated by the trains seriously affect the health of people along the line. Living and working, therefore, the control of the vibration and noise of the existing line has become an urgent problem to be solved in the operation line; The insulation resistance value of the rail to the ground is reduced, and the stray current of the track corrodes the pre-buried pipeline of the line

[0004]Aiming at the protection of line vibration, noise and stray current, operating units in various places have adopted various transformation measures, but there are still many problems in the current transformation measures, and the transformation effect cannot be achieved. Fully meet the line operation requirements
