FIELD: construction.
SUBSTANCE: reinforced-concrete supporting block made in the form of a trapezoid in a cross section is reinforced with wire and/or bars and/or ropes. In an under-rail zone there is a cavity with embedded elements (dowels) for attachment of a rail. Embedded elements additionally located on a horizontal level contribute to attachment of a bracket of a contact rail. On side surfaces there are conduits.
EFFECT: possible installation of a bracket of a contact rail on a supporting block; increasing strength and service life parameters, reliable anchorage and adhesion of the supporting block to a concrete foundation.
