FIELD: construction.
SUBSTANCE: prefabricated rail cover comprises solid reinforced concrete track slabs placed on a bearing substrate and laid as butt-joined with channels in the form of parallel locating blocks, in which aflush with the upper surface of the slabs on elastic substrates there are rails installed that are connected to each other by means of welding. The cover is made in the form of a set from two types of blocks. The invention also relates to the methods for fixation of track rails to slabs for both types of blocks. Besides, the invention relates to the slab design for blocks with helical fastening elements.
EFFECT: high operational reliability of a cover, simplified repair and replacement of a cover.
