Zusammenfassung: | The invention relates to the technical field of rail engineering and particularly relates to a metro operation line short sleeper rail cant over-limit treatment grinding method. The method comprises the following steps that S1, overrun measurement is conducted on short sleepers, and the short sleepers with the overrun range of 0-5mm as short sleepers are made to be ground; S2, for the to-be-polished short sleeper, after a fastener is detached and a steel rail is lifted, a polishing support is installed and polishing is conducted; and S3, after polishing is completed, the steel rail is fixed again. Compared with the prior art, the method is advantaged in that the process is simple, the work amount of work is relatively small, and work efficiency can be improved; the original ballast bed structure is not damaged, and the original ballast bed stability is kept; external influence is small, an interval power supply meets construction conditions, and noise is low; the inclination of part of the supporting blocks i |
