摘要

FIELD: construction.;SUBSTANCE: track upper structure prestressed reinforced concrete plates are tied along the track into 10 to 100 m-long packages with the help of stressed steel ropes passing at the center of plates. Rubber sealing elements are fitted on the said ropes between the plates. The ends of said ropes are furnished with concreted anchors arranged in fixture rectangular cavities. The gap varying from to 50 to 100 mm is provided for between the plates after tensioning and fixing steel ropes.;EFFECT: safe and equal-strength track, high bending resistance of rails, faster track construction shorter repair and replacement.;2 cl, 3 dwg
