FIELD: machine building.
SUBSTANCE: inventions can be implemented at construction and reconstruction of crossing of mains (M) over rail and motor roads. The essence of the invention is like follows: tube space between M and protective jacket (PJ) is filled with a plastic mass on base of synthetic high molecular compounds. Further, the procedure for fabrication consists in filling tube space M-PJ either with heated plastic through collectors or under pressure through a vent stalk of the PJ.
EFFECT: increased reliability and service life of crossing due to increased rigidity and moisture resistance of system, raised processability of fabrication of new and reconstruction of old crossings.
