Description

Die Erfindung betrifft ein Verfahren zum Stabilisieren eines Erdplanums eines Gleises, wobei das nach Entfernen des Gleises und Schotters freigelegte Erdplanum mit Zuschlagstoffen vermischt sowie unter Bildung einer Schutzschichte eingeebnet und verdichtet wird. Die Erfindung betrifft außerdem eine Maschine zur Durchführung des Verfahrens.The invention relates to a method for stabilizing a Erdplanums a track, wherein the exposed after removal of the track and ballast Erdplanum mixed with aggregates and is leveled to form a protective layer and compacted. The invention also relates to a machine for carrying out the method.

Gemäß AT 513 248 ist ein Verfahren zur Reinigung bzw. Erneuerung von Schotter eines Gleises bekannt. Die dabei eingesetzte Gleisbaumaschine ist in der gleislosen Baustelle über zwei Raupenfahrwerke abgestützt. Der durch eine Räumvorrichtung aufgenommene Schotter wird in einer Siebanlage gereinigt und in Arbeitsrichtung vor dem vorderen Raupenfahrwerk in einer ersten Teilmenge zur Bildung einer Schotterlage abgeworfen, auf der die beiden Raupenfahrwerke unter Schonung des Erdplanums verfahren werden. Hinter dem zweiten Fahrwerk erfolgt die Einbringung und Planierung der restlichen Schottermenge zur Herstellung eines exakten Schotterplanums.According to AT 513 248 is a method for cleaning or renewal of ballast of a track known. The track-laying machine used for this purpose is supported by two crawler tracks in the trackless construction site. The gravel collected by a clearing device is cleaned in a screening plant and dropped in the working direction in front of the front crawler undercarriage in a first subset to form a gravel layer on which the two crawler tracks are moved while preserving the Erdplanums. Behind the second chassis, the introduction and planing of the remaining amount of ballast takes place to produce an exact gravel road.

EP 2 054 552 B1 beschreibt ebenfalls eine auf Raupenfahrwerken verfahrbare Maschine zum Erneuern einer Schotterbettung. Auf ein - durch Schotterentfernung hinter dem vorderen, auf dem alten Schotterbett abrollenden Fahrwerk freigelegtes - Planum wird zuerst eine Unterlage aus Geotextil oder Geogitter verlegt, auf welche sodann eine Sandschichte und auf diese eine Neuschotterschichte aufgebracht und verdichtet werden. Das zweite Raupenfahrwerk der Maschine fährt auf dem dadurch hergestellten neuen Schotterbett. EP 2 054 552 B1 also describes a crawler traveling machine for renewing a ballast bed. On a - by ballast removal behind the front, unrolling on the old ballast bed suspension - Planum is first a base laid from geotextile or geogrid, on which then a sand layer and on this a Neuschotterschichte be applied and compacted. The second crawler chassis of the machine travels on the new ballast bed made by it.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung eines Verfahrens bzw. einer Maschine der eingangs genannten Art, mit dem bzw. der eine verbesserte Untergrundsanierung möglich ist.The object of the present invention is now to provide a method or a machine of the type mentioned, with which or an improved subsurface restoration is possible.

Diese Aufgabe wird erfindungsgemäß mit einem Verfahren und einer Maschine der gattungsgemäßen Art durch die im Kennzeichen des Hauptanspruches bzw. des Anspruchs 5 angeführten Merkmale gelöst.This object is achieved by a method and a machine of the generic type by the features stated in the characterizing part of the main claim or of claim 5.

Ein derartiges Verfahren hat den Vorteil, dass die Bildung einer Sanierungsschichte möglich ist, ohne dass diese vor der Fertigstellung noch mit einem - zu einer ungleichmäßigen Verdichtung führenden - Fahrwerk befahren werden muss. Damit kann mit relativ geringem Verfahrensaufwand eine optimale Qualität der Sanierungsschichte sichergestellt werden.Such a method has the advantage that the formation of a rehabilitation layer is possible without having to drive it before completion with a - leading to an uneven compression - chassis. This can be ensured with relatively little process cost optimal quality of the redevelopment layer.

Eine gemäß den Merkmalen von Anspruch 5 ausgebildete Maschine hat den Vorteil, dass der für die Sanierung des Erdplanums erforderliche konstruktive Aufwand relativ gering ist. Außerdem können bereits im Einsatz befindliche und durch den zitierten Stand der Technik bekannte, für eine Schotterreinigung vorgesehene Maschinen für eine zusätzliche Einsatzvariante in einfacher Weise nachträglich umgebaut (bzw. auch einfach wieder rückgebaut) werden.A trained according to the features of claim 5 machine has the advantage that the required for the rehabilitation of Erdplanums design effort is relatively low. In addition, already in use and known by the cited prior art, provided for a ballast cleaning machines for an additional Insert variant easily retrofitted (or simply dismantled).

Weitere Vorteile der Erfindung ergeben sich aus den übrigen Unteransprüchen und der Zeichnungsbeschreibung.Further advantages of the invention will become apparent from the remaining dependent claims and the drawing description.

Im Folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher beschrieben. Es zeigen: Fig. 1 und 2 jeweils eine Seitenansicht einer - während zweier unterschiedlicher Arbeitsdurchgänge abgebildeten - Maschine zur Durchführung des erfindungsgemäßen Verfahrens.In the following the invention will be described with reference to an embodiment shown in the drawing. Show it: Fig. 1 and 2 in each case a side view of a - during two different working operations mapped - machine for carrying out the method according to the invention.

Eine in der Zeichnung ersichtliche, zur Untergrundsanierung eines Gleises dienende Maschine 1 weist einen Maschinenrahmen 2 auf, der mit zwei endseitig angeordneten Schienenfahrwerken 3 ausgestattet ist. Zwischen diesen sind ein - bezüglich einer Arbeitsrichtung 4 - vorderes Raupenfahrwerk 5 und ein hinteres Raupenfahrwerk 6 über Antriebe 7 höhenverstellbar mit dem Maschinenrahmen 2 verbunden, an dem außerdem noch eine Räumkette 8 zur Aufnahme von Schotter 9, eine Siebanlage 10, eine Arbeitskabine 11 und ein Motor 12 vorgesehen sind.An apparent in the drawing, for the underground rehabilitation of a track serving machine 1 has a machine frame 2, which is equipped with two end arranged rail bogies 3. Between these are - with respect to a working direction 4 - front crawler chassis 5 and a rear crawler chassis 6 via drives 7 height adjustable connected to the machine frame 2, on which also still a clearing chain 8 for receiving gravel 9, a sieve 10, a work booth 11 and a Motor 12 are provided.

Am hinteren Ende des Maschinenrahmens 2 ist eine Abwurfvorrichtung 22 in Form eines eine Auslassöffnung 14 aufweisenden Schüttgutspeichers 13 angeordnet, dem eine Planier- und Verdichtvorrichtung 15 bezüglich der Arbeitsrichtung 4 nachgeordnet ist. Vor dem Schüttgutspeicher 13 befindet sich eine durch Antriebe 16 höhenverstellbare Aufreißvorrichtung 17 mit in einer Maschinenquerrichtung voneinander distanzierten Aufreißzähnen 18.At the rear end of the machine frame 2, a discharge device 22 in the form of an outlet opening 14 having bulk storage 13 is arranged, which is a grading and compacting device 15 downstream with respect to the working direction 4. Before the bulk material storage 13 is a height adjustable by 16 drives tearing device 17 with tear teeth 18 spaced apart in a cross-machine direction.

Das erfindungsgemäße Verfahren zum Stabilisieren eines Erdplanums 19 des Gleises beginnt - nach erfolgtem Abbau der Schienen und Schwellen des Gleises - mit der Entfernung des Schotters 9 anhand der Räumkette 8 in einem in Fig. 1 dargestellten ersten Arbeitsdurchgang. Die Maschine 1 wird dabei mittels der abgesenkten Raupenfahrwerke 5 und 6 kontinuierlich auf dem durch die vorgeordnete Räumkette 8 freigelegten Erdplanum 19 verfahren. Der in der Siebanlage 10 gereinigte Schotter und der dabei anfallende Abraum wird über Förderbänder 23 in (nicht dargestellte) auf dem Nebengleis befindliche Materialwagen zur Zwischenspeicherung verladen.The inventive method for stabilizing a Erdplanums 19 of the track begins - after the dismantling of the rails and sleepers of the track - with the removal of the ballast 9 using the Räumkette 8 in a in Fig. 1 illustrated first work pass. The machine 1 is thereby moved by means of the lowered crawler tracks 5 and 6 continuously on the uncovered by the upstream clearing 8 Erdplanum 19. The cleaned in the sieve 10 ballast and the resulting spoil is loaded via conveyor belts 23 in (not shown) located on the siding material cart for intermediate storage.

Parallel dazu erfolgt in einem bezüglich der Arbeitsrichtung 4 an das hintere Raupenfahrwerk 6 anschließenden Arbeitsabschnitt 20 eine Auflockerung des Erdplanums 19 durch die Aufreißzähne 18 und eine Vermischung mit Zuschlagstoffen 30 (wie z.B. einem Kalk-Zement-Gemisch), die über die Auslassöffnung 14 des Schüttgutspeichers 13 eingebracht werden. Unmittelbar danach wird das Erdplanum 19 mittels der Planier- und Verdichtvorrichtung 15 eingeebnet und unter Bildung einer Schutzschichte 21 verdichtet.In parallel, in a working section 20 adjoining the rear crawler track 6 with respect to the working direction 4, loosening of the ground plane 19 by the tearing teeth 18 and mixing with aggregates 30 (such as a lime-cement mixture) via the outlet opening 14 of the bulk material store takes place 13 are introduced. Immediately thereafter, the Erdplanum 19 is leveled by the leveling and compacting device 15 and compacted to form a protective layer 21.

In einem in Fig. 2 dargestellten zweiten Arbeitsdurchgang wird nun das mit den Zuschlagstoffen 30 versetzte Erdplanum 19 durch die Räumkette 8 aufgenommen und über die Siebanlage 10 zu einer hinter dem hinteren Raupenfahrwerk 6 gelegenen Abwurfstelle 24 weitertransportiert. Dabei tritt ein vorteilhafter Mischeffekt auf, der noch verstärkt wird durch das vibrierende Sieb der Siebanlage 10, über das das Material mit Hilfe eines Abdeckblechs geleitet wird. Das auf das freigelegte Erdplanum 19 abgeworfene Planumsmaterial wird anhand einer Verdichteinrichtung 25 planiert und verdichtet und dadurch eine Sanierungsschichte 26 gebildet.In an in Fig. 2 shown second work cycle is now offset with the aggregates 30 Erdplanum 19 through the clearing chain Recorded 8 and transported on the screen 10 to a located behind the rear crawler chassis 6 discharge point 24. In this case, an advantageous mixing effect occurs, which is reinforced by the vibrating sieve of the screen 10, over which the material is passed by means of a cover plate. The dropped onto the uncovered Erdplanum 19 tarpaulin material is leveled and compacted by means of a compactor 25, thereby forming a rehabilitation layer 26.

Auf diese Sanierungsschichte 26 kann in weiterer Folge Kies 27 abgeworfen werden, der bei der Schotterreinigung als noch brauchbarer Abraum abgeschieden und zwischengelagert wurde und der nun zur Bildung einer Schutzschichte 28 planiert wird, wie ganz rechts in Fig. 2 zu sehen. Ebenso kann wahlweise der durch die Räumkette 8 aufgenommene und in der Siebanlage 10 gereinigte Schotter 9 nach der Zwischenspeicherung zur Bildung einer Schotterbettung auf die Sanierungsschichte 26 abgeworfen werden.Gravel 27 can subsequently be dropped onto this remediation layer 26, which gravel was separated and stored as still acceptable waste during ballast cleaning and which is now leveled to form a protective layer 28, such as the far right in FIG Fig. 2 to see. Likewise, alternatively, the gravel 9 taken up by the broaching chain 8 and cleaned in the screening plant 10 can be thrown off the reorganization layer 26 after the intermediate storage to form a ballast bedding.

Zusätzlich besteht auch noch die Möglichkeit, vor dem Abwurf von Kies 27 eine Folie 29 auf die Sanierungsschichte 26 abzulegen.In addition, it is also possible to deposit a film 29 on the redevelopment layer 26 before the discharge of gravel 27.
