Operational method for stabilizing tracks in turnout zone

Abstract

The invention discloses an operational method for stabilizing tracks in a turnout zone. The operational method is used for maintenance construction for the tracks, and stabilizing operation is carried out for the tracks by a track stabilizing unit. The operational method includes that a, during stabilizing operation for the turnout zone, the track stabilizing unit carries out double-side track clamping and vibratory stabilizing operation for the track in a starting section of the turnout zone; b, the track stabilizing unit carries out single-side linear basic track clamping or curved basic track clamping and vibratory stabilizing operation for the tracks in a switch section, a transitional section and a frog section; and c, linear branches and curved branches of a turnout are subjected to stabilizing operation at least twice, in other words, the linear branches are subjected to stabilizing operation once and the curved branches are subjected to stabilizing operation once. The operational method has the advantages that resistance of a ballast bed can be recovered, the running safety can be improved, low-speed passing limit after turnout maintenance operation can be relieved, the geometric shape of routes of the turnout can be kept for a long time after the turnout is stabilized, the quality of the routes of the turnout zone can be improved, the turnout maintenance cycle can be prolonged, and the turnout maintenance cost can be lowered.

Description

technical field [0001] The invention relates to an operation method for stabilizing a track in a turnout area, and belongs to the field of track maintenance construction methods. Background technique [0002] The fasteners of the turnout, the arrangement of rails and the driving device for changing lanes are complex, and the existing dynamic stabilization device cannot smoothly operate continuously in the turnout area. There is a sharp rail at the switch point of the turnout. If the existing stabilizing device is used for stabilizing work with the same operation method as the main line, there will be a danger of climbing rails and derailment; at the frog of the turnout, the clamp wheel of the stabilizing device It is impossible to clamp the rail, so the switch and the frog section of the turnout are the links where the stabilizing device is difficult to integrate with the rail. [0003] At present, there are no mature means of stable operation in the turnout area at home an...

AI Technical Summary

Problems solved by technology

After the tamping operation of the line in the turnout area, although the track has a good geometric state, the ballast density in the turnout area is uneven, and the resistance of the ballast bed decreases. The lateral resistance of the track can only be gradually restored by passing at a slow speed.
