Benefits of technology

[0004]The object of the invention is therefore to indicate a fixed carriageway for rail vehicles whose manufacture can be made simpler and more cost-effective.
[0011]A particularly good vibration damping effect can be achieved if the concrete support panel is mounted resiliently in a trough. On the base of the trough are the resilient elements, on which the concrete support panel is laid. Since the concrete support panel can move relative to the trough, the desired technological decoupling of vibration is achieved. By the controlled selection of the mass of the concrete support panel and of the properties of the resilient elements, vibrations of a certain frequency range can be suppressed in a controlled manner.

Problems solved by technology

Thus the stage necessary hitherto of forming casing for the concrete support panel becomes superfluous.

Embodiment Construction

[0015]The fixed carriageway shown in FIG. 1 is used in a tunnel and comprises a trough 2, in which a concrete support panel 3 is resiliently mounted. At the same time, reference is made to FIG. 2, which shows a section through the fixed carriageway 1 shown in FIG. 1 transverse to the direction of travel.

[0016]In manufacturing the fixed carriageway 1, resilient elements formed as strip bearings 5 and formed of elastomer material are laid on the base face 4 of the trough 2.

[0017]On the resilient elements, a prefabricated panel 6 is laid, which has on its upper face 7 a projecting connecting reinforcement 8. Additionally laid and aligned on the prefabricated panel 6 are longitudinal reinforcements 9 and optionally transverse reinforcements (not shown) as well as sleepers 10, which are assembled to form a track grid with rail fixings 19, rails 18 and longitudinal reinforcements 9. In the example shown, dual-block sleepers are used, whose sleeper blocks 11, 12 are respectively connected ...

Abstract

Fixed carriageway for rail vehicles, which is mounted on resilient elements, the concrete support panel including prefabricated panels and a layer of in-situ concrete applied thereon, wherein the prefabricated panels rest on the resilient elements and form a monolithic bond with the in-situ concrete.

Description

BACKGROUND OF THE INVENTION[0001]The invention relates to a fixed carriageway for rail vehicles which is mounted on resilient elements.[0002]When rail vehicles pass over carriageways, vibrations are generated which are transmitted through the subsoil and can thus be noticed even in adjacent buildings. In order to reduce or completely eliminate such unwanted vibrations, it is already known to configure the carriageway as a sprung-mass system. The carriageway is in this case formed as a separate vibratable mass, which is mounted movably with respect to the subsoil via a resilient element acting as a spring. The resilient element, which is disposed between the vibratable carriageway and the subsoil, e.g. a tunnel structure, in this case effects decoupling of the vibrations, so that the size of the vibrations transferred to the subsoil does not exceed a certain level.[0003]The assembly of a carriageway by the in-situ method of construction with pre-placed resilient elements is however r...
