Abstract
A method for installing a steady rail track, for which the concrete railroad ties, which carry the rails or auxiliary rails and the continuous reinforcement of which protrudes below out of the only partially constructed concrete casing, are preinstalled initially into a rail grid and subsequently lined up positionally over a supporting layer and embedded in a casting composition, the rail grid, with interposing of a supporting reinforcement, which is optionally tied to the underside of the railroad tie reinforcement, being aligned directly over a hydraulically bound supporting layer and the casting composition, preferably using movable, removable side formwork, is applied on the hydraulically bound supporting layer.
Claims20
A method for installing a steady rail track, comprising:
- providing concrete railroad ties for carrying rails, each concrete railroad tie including a continuous railroad tie reinforcement which protrudes below out of a partially constructed concrete casing;
- pre-installing the concrete railroad ties by arranging the concrete railroad ties into a rail grid and aligning the rail grid directly over a hydraulically bound supporting layer;
- interposing a supporting reinforcement between the supporting layer and the rail grid;
- and
- applying a casting composition on the hydraulically bound supporting layer to embed the supporting reinforcement and concrete railroad ties in the casting composition.
A railroad tie for installation above a hydraulically bound supporting layer comprising:
- a partially constructed concrete casing;
- a continuous railroad tie reinforcement having a portion which protrudes below out of the partially constructed concrete casing;
- a supporting reinforcement between the continuous railroad tie reinforcement and the hydraulically bound supporting layer;
- a casting composition disposed on the hydraulically bound supporting layer, said concrete casing along with said protruding portion of said continuous railroad tie reinforcement being embedded within said casting composition;
- an upper side of the partially constructed concrete casing including inclined stripping edges for the casting composition which extend from one end of the railroad tie to the other, inclined to a running plane of the rails.
A method of installing a railroad track above a hydraulically bound supporting layer comprising:
- providing a partially constructed railroad tie for carrying rails, constructing said partially constructed railroad tie by forming a concrete casing provided with a railroad tie reinforcement disposed such that a protruding portion of said railroad tie reinforcement protruders from the bottom of said concrete casing;
- pre-assembling a plurality of said partially constructed railroad ties and tracks into a pre-assembled rail grid above said hydraulically bound supporting layer;
- interposing a supporting reinforcement between the supporting layer and the rail grid;
- applying a casting composition between the supporting layer and the partially constructed railroad ties;
- embedding said protruding portion of said railroad tie reinforcement within said casting composition;
- and
- providing a connection between said supporting reinforcement and the protruding portion of said railroad tie reinforcement prior to applying said casting material.
A method for installing a steady rail track, comprising:
- providing concrete railroad ties for carrying rails, each concrete railroad tie including a continuous railroad tie reinforcement which protrudes below out of a partially constructed concrete casing;
- pre-installing the concrete railroad ties by arranging the concrete railroad ties into a rail grid and aligning the rail grid directly over a hydraulically bound supporting layer;
- interposing a supporting reinforcement between the supporting layer and the raid grid;
- aligning the height and a side of each of the concrete railroad ties comprising the grid via adjusting spindles;
- and
- applying a casting composition on the hydraulically bound supporting layer to embed the concrete railroad ties in the casting composition.
A railroad tie for installation above a hydraulically bound supporting layer comprising:
- a concrete casing;
- a railroad tie reinforcement having a portion which protrudes below out of the concrete casing;
- a supporting reinforcement between the railroad tie reinforcement and the hydraulically bound supporting layer;
- and
- a casting composition disposed on the hydraulically bound supporting layer, said concrete casing along with said protruding portion of said railroad tie reinforcement being embedded within said casting composition.
