Embodiment

[0027] Embodiment: An embedded track changing method includes the following steps:

[0028] Step 1: Release the constraints on the polymer composite materials on both sides of the rail. In step 1, use ultra-high pressure waterjet to cut the polymer composite material on the edge of the rail groove steel plate to separate it from the rail groove, thereby releasing the constraints on both sides of the rail.

[0029] Step 2: Saw the rail. In the second step, use a rail saw to cut the rail at the seam position of the rail plate where the rail to be replaced is located.

[0030] Step three, take out the rail. In step three, use a jack to push the rail out of the rail groove at the position of the plate seam of the track plate where the rail to be replaced is successfully taken out.

[0031] Step 4. Grind and clean the supporting rail groove. In step four, use a grinder to polish the residual polymer material in the rail groove and remove dust.

[0032] Step 5. Put the backing plate in th...

Abstract

The invention discloses an embedded rail replacing method. The embedded rail replacing method comprises the steps that 1, the constraint borne by polymer composites on the two sides of a steel rail is relieved; 2, the steel rail is sawn off; 3, the steel rail is taken out; 4, a rail ditch is polished and cleaned; 5, a backing plate is placed in the rail ditch; 6, a new steel rail is placed in the rail ditch; 7, the steel rail is welded; 8, fine tuning is performed on the steel rail; 9, polymers are poured. The embedded rail replacing method has the advantages that the rail is replaced specially for the characteristics of an embedded rail system, the operation difficulty is low, and the technical blank is filled up.

Description

Technical field [0001] The invention relates to the field of track technology, in particular to an embedded track changing method. Background technique [0002] The embedded ballastless track is a new type of track structure. Its main feature is to bury the steel rail in the track bed slab bearing groove and lock the steel rail through polymer materials. The traditional fastener-type track bed plate structure only needs to cut the rail to replace the new rail and weld it when changing the rail. However, due to the new development of the embedded ballastless track, there is no special rail changing method at this stage. Therefore, it is necessary to develop a new type of track changing method for the embedded ballastless track to solve the track changing and related problems of the embedded ballastless track. Summary of the invention [0003] The purpose of the present invention is to provide an embedded track rail changing method in view of the above existing problems, which main...
