FIELD: railway track structure construction.
SUBSTANCE: invention relates to the field of the railway track structure construction, in particular to methods of restoration of the concrete base of the rail track. To restore the broken anchor, the central part of the anchor head is cut out with a hollow core drill from the inside to the level at which the head goes into the leg. The head of the anchor is removed. Then a round hole is cut out with a core drill around the anchor leg until the level of the lower end of the leg is reached. The leg of the fastener is removed along with the cut out concrete cylinder. Annular grooves are cut on the surface of the hole. An adhesive composition and a leg of a new fastener are introduced into the hole and grooves. The head is positioned in the design position until the composition is cured.
EFFECT: reduces the complexity of the restoration of the concrete base.
