Abstract

The invention relates to a method for stabilizing a subgrade (19) that has been exposed after a track and ballast have been removed, wherein, in a first work pass, in a work segment (20) adjoining a rear tracked chassis with respect to a working direction (4), in parallel with the removal of the ballast (9), a loosening of the subgrade (19), an introduction of additives (30), and a leveling occur. In a second work pass, the subgrade (19) mixed with additives is throughly mixed by being picked up by means of an excavating chain (8) and by being transported further to a throw-off point (24) behind the rear tracked chassis (6) and is thrown off back onto the exposed subgrade (19), whereupon a restoration layer (26) is formed by leveling and compacting the thrown-off subgrade.

Description

Verfahren zum Stabilisieren eines Erdplanums  Method of stabilizing a soil
[01] 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 excavated 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.
[02] 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.  [02] According to AT 513 248 a method for cleaning or renewing ballast of a track is 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.
[03] EP 2 054 552 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. [03] EP 2 054 552 likewise describes a machine movable on crawler tracks 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.
[04] 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 or an improved underground remediation is possible.
[05] Diese Aufgabe wird erfindungsgemäß mit einem Verfahren und einer  [05] This object is achieved according to the invention with a method and a
Maschine der gattungsgemäßen Art durch die im Kennzeichen des Hauptanspruches bzw. des Anspruchs 5 angeführten Merkmale gelöst.  Machine of the generic type solved by the features cited in the characterizing part of the main claim or of claim 5.
[06] 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.  [06] Such a method has the advantage that the formation of a redevelopment layer is possible without it having to be driven before the completion of a - leading to an uneven compression - chassis. This can be ensured with relatively little process cost optimal quality of the redevelopment layer.
[07] 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).
[08] Weitere Vorteile der Erfindung ergeben sich aus den übrigen Unteransprüchen und der Zeichnungsbeschreibung.  [08] Further advantages of the invention emerge from the remaining subclaims and the description of the drawings.
[09] 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.  [09] In the following the invention will be described in more detail with reference to an embodiment shown in the drawing. 1 and 2 each show a side view of a machine - embodied during two different working passages - for carrying out the method according to the invention.
[10] 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.
[11] Am hinteren Ende des Maschinenrahmens 2 ist eine Abwurfvorrichtung  [11] At the rear end of the machine frame 2 is a discharge device
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 Aufreiß- Vorrichtung 17 mit in einer Maschinenquerrichtung voneinander distanzierten Aufreißzähnen 18. 22 arranged in the form of an outlet opening 14 having bulk material storage 13, which is a grading and compacting device 15 downstream with respect to the working direction 4. In front of the bulk material storage 13 is a height-adjustable by drives 16 Aufreiß- Device 17 with tear teeth 18, which are distanced from each other in a cross-machine direction.
[12] Das erfindungsgemäße Verfahren zum Stabilisieren eines Erdplanums  [12] The inventive method for stabilizing a 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.  19 of the track begins - after the dismantling of the rails and sleepers of the track - with the removal of the ballast 9 on the basis of the clearing chain 8 in a first working passage shown in Fig. 1. 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.
[13] 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 respect to the working direction 4 to the rear crawler chassis 6 subsequent work section 20 a loosening of Erdplanums 19 by the Aufreißzähne 18 and mixing with aggregates 30 (such as a lime-cement mixture), via the outlet opening 14 of the bulk material storage 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.
[14] In einem in Fig. 2 dargestellten zweiten Arbeitsdurchgang wird nun das mit den Zuschlagstoffen 30 versetzte Erdplanum 19 durch die Räum- kette 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 Erdpla- num 19 abgeworfene Planumsmaterial wird anhand einer Verdichteinrichtung 25 planiert und verdichtet und dadurch eine Sanierungsschichte[14] In a second working pass shown in FIG. 2, the earth planum 19 offset with the additives 30 is taken chain 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 tarpaulin material dumped onto the excavated earth plane 19 is leveled and compacted by means of a compacting device 25 and thereby a remediation layer
26 gebildet. 26 formed.
[15] 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 Zwi- schenspeicherung zur Bildung einer Schotterbettung auf die Sanierungsschichte 26 abgeworfen werden.  Gravel 27 can subsequently be dropped onto this redevelopment layer 26, which gravel was deposited as usable scrap in the ballast cleaning and is now leveled to form a protective layer 28, as can be seen on the far right in FIG. Likewise, alternatively, the gravel 9, which has been taken up by the clearing chain 8 and cleaned in the screening plant 10, can be thrown onto the remediation layer 26 after the intermediate storage to form a ballast bed.
[16] Zusätzlich besteht auch noch die Möglichkeit, vor dem Abwurf von Kies  In addition, there is also the possibility of dropping gravel
27 eine Folie 29 auf die Sanierungsschichte 26 abzulegen.  27 to deposit a film 29 on the rehabilitation layer 26.
