Embodiment Construction

[0022] figure 1 The shown fixed track road 1 essentially consists of a road slab 2 made of concrete, which is supported on a foundation 3 . In the exemplary embodiment shown, the foundation is designed as a hydraulically connected base layer.

[0023] The sleeper is embedded in the road slab 2 , the individual blocks 4 , 5 of the sleeper supporting the rails 6 , 7 . exist figure 1 The middle triangle 8 represents a mark whose lower apex gives the nominal height of the rail 6 . Due to the sinking of the foundation 3 , a difference in height h results, which gives the deviation between the nominal height and the actual height of the rail 6 .

[0024] To correct said height difference, the pavement slab 2 is separated from the foundation 3, taking care not to damage the pavement slab 2 and the foundation 3 here. The separation thus takes place precisely at the contact surface 9 between the pavement slab 2 and the foundation 3 . After separation, the pavement slab 2 is loosel...

Abstract

The invention relates to a method for correcting the height of a fixed railway track, wherein the sleepers supporting the tracks are embedded in a track plate which is arranged on the foundation. Said method comprises the following steps: the track plates are separated from the base on the common contact surface, filling openings, which extend from the upper side to the lower side of the track plate, are applied thereon, the track plate is lifted until a desired height is reached, a liquid sealing material which fills the free chamber between the track plate and the foundation is introduced through the filling openings and pressure surges are separated.

Description

technical field [0001] The present invention relates to a height correction method for fixed rail tracks, wherein sleepers supporting the rails are embedded in road slabs placed on foundations / roadbeds. Background technique [0002] Various methods of producing fixed-track roads are known, for example from DE 196 53 858 A1. Typically, in fixed track roads, the ties that support the rails are cast into the road slab. The road slab is in turn placed on a foundation, here the term "foundation" is used in this patent application to denote various types of substructure, which can also be, for example, a hydraulically connected base (HGT). [0003] In practice, the problem arises that the actual height of the track deviates from the predetermined setpoint height over time, where the deviation is mainly caused by subsidence of the substructure. In the case of previously used gravel tracks, such errors can be eliminated in a relatively simple manner by a backfilling process. With...
