DE3309046A1 - Track rebuilding method without rail removal, characterised in that, in short track sections, the sleepers are displaced and the remaining ballast is conveyed to the displaced sleepers - Google Patents

Abstract

In this connection, the installed rails remain in their old position, the sleepers are displaced with a displacing device, moved to the new place of installation with a sleeper transport waggon and mounted here. The ballast then exposed is conveyed to the newly mounted sleepers and installed here. Advantages: a) From the point of view of railway operation No interruption of the continuously welded-together rails and consequently no additional welded joints. Increased travelling safety and travelling comfort as no rail joints present. Reliability of maintaining the stipulated closure period and consequently reliability of the scheduled running of the railway operation, as the track can always be used again in approximately 30 minutes. b) From an economical point of view No installation and removal of yoke rails (auxiliary rails) No additional welding work with the associated loosening and retightening work. Considerably greater rebuilding capacity in short closure periods Diverse application possibilities, above all in limited space conditions (e.g. in a tunnel), in short closure periods, in sleeper replacement, in ballast cleaning and ballast replacement and in track formation improvement work without an adjacent track. e

Description

The technical field is track construction at the Deutsche Bundesbahn, Ver

Sweeping operations and private sidings, The invention relates a remodeling process, whereby the built-in track rails are left; special in the case of cramped space conditions and short breaks Technique, this work is either done by hand or by expansion of the track section to be rebuilt, the criticism of the current state of technology is the risk of exceeding the blocking times and the lower driving safety, as well as a reduction in driving comfort by cutting the rails and a correspondingly low performance in the short lockout period required for work on Available.

The invention is based on the object of a safe and economical Track renewal to be carried out during closed breaks. This object is achieved according to the invention triggered that the rails are not removed. The sleepers will either only postponed or replaced. The gravel is shifted, it can also getting cleaned. It is also possible to load the ballast. With accordingly unsuitable subsoil under the gravel, it is possible to develop this material and to load.

One embodiment of the invention is the installation of sub-ballast mats (Noise protection mats) in the S-Bahn tube (tunnel) to achieve the required noise protection in the nearby cultural center (concert hall) of the city of Munich on "Gasteig" reach. Since the S-Bahn could not be stopped, the work had to be done can be carried out during nightly closed breaks.

-1 1st section (1st conversion) At the start of the renovation, 8 sleepers will be removed and stored for later reinstallation. The one under the dismantled sleepers now exposed ballast is laid to a length of 5 m with one on the rails loaded moving excavator on a gravel transport wagon. After cleaning the tunnel floor to be isolated from gravel abrasion and to compensate for uneven concrete the sound insulation mats are laid or glued to the tunnel sole.

2nd section and others: sections Now the second renovation cycle begins.

The first sleeper, which is still in the gravel, is fitted with a track-driven one Excavator attached to one sleeper each shifting device (in direction section already covered with mats) moved approx. 1 m from the gravel bed. The sleeper to be moved is on a sleeper transport trolley that rolls on the rails suspended in the ribbed plate and is moved up to the new assembly point (approx. 5 m ) pushed further by hand.

The threshold is at the point provided with the threshold division with a mounting device which is attached to the sleeper transport trolley up to raised to the rail foot and mounted in their final position.

The second and third threshold are as just described with the excavator pushed out of the ballast bed and mounted in the intended place.

The now exposed gravel (approx. 1.80 m long) is covered with the Excavator picked up, move up to the 3 newly installed sleepers and here again built-in.

This workflow is repeated up to a range of 8 thresholds (5 m) the tunnel floor is exposed again and the sound insulation mats are installed can.

All other sections proceed as in section 2, .1 3rd section, last section in a blocking puse In the from the previous Arbbitstakt exposed approx. 5 m section are after inserting the insulating mats the im 1st conversion cycle removed sleepers and reinstalled in the 1st conversion cycle unload loaded ballast at this point.

The workflow for a lockout for this patent pending The conversion process is now complete. The rest of them follow as usual Tamping work and the clearing of the construction site for the scheduled resumption of the railway company.

The service required by the client during the nightly blocking period was 12 meters, the performance achieved by the invention could be increased to 30 meters will.

Claims (1)

Claim for a track renovation ferry without expanding the track characterized in that (after a preparatory section in which some thresholds removed, stored on the side and the gravel exposed here also removed was) in short track sections the sleepers with a shifting device (additional device on the excavator), with a sleeper transport and assembly trolley to the new one Installation site, evaluate installed according to the threshold division and the built-in ballast is transported to the shifted sleepers.
