The invention discloses a limiting boss elastic buffer
cushion layer for a ballastless track, and relates to the technical field of the track traffic equipment industry, the limiting boss elastic buffer
cushion layer comprises a lower
flanging structure, a lower structure and an upper structure, the lower
flanging structure is arranged on the outer edge of the bottom of the lower structure, and a clamping structure is arranged between the upper structure and the lower structure; the alignment mechanism is used for aligning the upper structure and the lower structure; the detection mechanism is used for detecting whether the upper structure and the lower structure are aligned or not; after the limiting boss elastic buffer
cushion layer is pre-embedded into a prefabricated slab mold, after the under-slab filling layer is poured and the
mold removal strength is achieved, the upper structure of the limiting boss buffer cushion layer is removed, and sealing treatment is conducted on the lower structure of the limiting boss buffer cushion layer through
sealant after the upper structure is removed; the
peripheral wall of the lower structure is designed to be provided with edges. In the use process of the limiting boss buffer cushion layer, after the top is crushed or gaps are formed, the
sealant on the top is directly removed, and the
sealant is injected again, so that the later maintenance and operation cost is remarkably reduced.
