Targeted white hair dyeing method

The invention relates to the technical field of rail transit, in particular to a targeted white hair dyeing method which comprises the following steps: S01, preliminarily measuring the elevation of a road, and pre-burying an iron plate on the basis of a rail structure; s02, rails and fasteners are laid on the iron plate; s03, remeasuring the track structure and the elevation of the road, and leveling a construction surface and a road surface by using cement mortar; s04, buckling a fastener cap on the fastener, enabling the end part of the transverse part of the fastener cap to abut against the track, and enabling the vertical part of the fastener cap to abut against the iron plate for fixation; s05, splicing the T-shaped iron and the flexible wrapping piece; s06, laying a track protection structure; s07, pouring a surface layer waterproof material; in practical application, the T-shaped iron, the flexible wrapping piece and the fastener cap can effectively prevent impact on a track structure when an automobil
