Diese Aufgabe wird bei einem Verfahren der genannten Art gelöst durch die Schritte:
- Ausbauen von Material aus einer Mischzone in einem Ãœbergangsbereich zwischen altem Schotterbett und altem Unterbau gemeinsam mit dem Altschotter des Schotterbetts,
- Abtrennen von Altschotter vom Ausbaumaterial,
- Mischen von nach Abtrennen von Schotter verbleibendem Ausbaumaterial, insbesondere Sand, Kies, Schotterabrieb und Unterkorn, mit bei der Aufbereitung von Altschotter anfallendem Material und/oder mit von extern zugeführtem Material, insbesondere Neumaterial, und Einbauen des mit Aufbereitungsmaterial und/oder externem Material gemischten Ausbaumaterials als eine oder Teil einer neuen, mechanisch verbesserten Unterbauschicht und/oder Planumsschutzschicht und/oder Frostschutzschicht sowie eventuell einer neuen zusätzlichen Zwischenschicht zwischen neuer, mechanisch verbesserter Unterbauschicht und Planums- und/oder Frostschutzschicht.

- Separating old ballast from the construction material,
- Mixing of remaining after separation of gravel expansion material, especially sand, gravel, gravel and undersize, with in the processing of old ballast accumulating material and / or externally supplied material, especially new material, and incorporating the mixed with treatment material and / or external material expansion material as one or part of a new, mechanically improved subgrade and / or level protection layer and / or antifreeze layer and possibly a new additional intermediate layer between new, mechanically improved subgrade layer and level and / or frost protection layer.
Bei einer Vorrichtung der genannten Art wird die Aufgabe dadurch gelöst, dass die erste Aushubeinrichtung zum gemeinsamen Ausbauen des Altschotters und von Material aus einer Mischzone in einem Übergangsbereich zwischen altem Schotterbett und altem Unterbau ausgebildet ist und dass eine Einrichtung zum Abtrennen von Altschotter vom Ausbaumaterial, eine Einrichtung zum Mischen von nach Abtrennen von Schotter verbleibendem Ausbaumaterial, insbesondere Sand, Kies, Schotterabrieb und Unterkorn, mit bei der Aufbereitung von Altschotter (4') anfallendem Material und/oder mit von extern zugeführtem Material, insbesondere Neumaterial, und eine Einrichtung zum Einbauen des mit Aufbereitungsmaterial und/oder externem Material gemischten Ausbaumaterials als eine oder Teil einer neuen, mechanisch verbesserten Unterbauschicht und/oder Planumsschutzschicht und/oder Frostschutzschicht vorgesehen sind sowie eventuell einer neuen zusätzlichen Zwischenschicht zwischen neuer, mechanisch verbesserter Unterbauschicht und Planums- und/oder Frostschutzschicht.In a device of the type mentioned, the object is achieved in that the first excavating device is designed for jointly removing the old ballast and material from a mixing zone in a transition region between old ballast bed and old substructure and that means for separating old ballast from the building material, a Device for mixing removal material remaining after separation of ballast, in particular sand, gravel, gravel and undersize, with material obtained during the treatment of old ballast (4 ') and / or with externally supplied material, in particular new material, and means for installing the build-up material mixed with conditioning material and / or external material are provided as or part of a new, mechanically improved undercoat and / or formation protection layer and / or antifreeze layer and possibly a new additional intermediate layer between new, mechanically improved undercoat layer and subgrade layer and / or frost protection layer.
Der Grundgedanke der Erfindung besteht darin, das Mischzonenmaterial gemeinsam mit dem Altschotter auszubauen und eine Trenneinrichtung vorzusehen, durch welche Altschotter von dem ausgebauten Material abgetrennt werden kann. Dabei kann die Einrichtung aus zwei oder mehr Trennstufen bestehen, wobei eine erste Trennstufe zum Abtrennen von groben Verunreinigungen, Wurzelwerk und Lehmbrocken ausgebildet ist, während eine zweite Trennstufe zum Abtrennen von Altschotter ausgebildet ist. Nach Abtrennen von Schotter verbleibendes Material, insbesondere Sand, Kies, Unterkorn und Abrieb, wird dann mit bei der Aufbereitung von Altschotter (4') anfallendem Material und/oder mit von extern zugeführtem Material, insbesondere Neumaterial, vermischt und als eine neue, mechanisch verbesserte Unterbauschicht und/oder Planumsschutzschicht und/oder Frostschutzschicht sowie eventuell eine neue zusätzliche Zwischenschicht zwischen neuer, mechanisch verbesserter Unterbauschicht und Planums- und/oder Frostschutzschicht wieder eingebaut. Auf diese Weise kann viel Ausbaumaterial wiederverwendet werden. Dies spart Neumaterial und verringert den Abraum.The basic idea of the invention is to expand the mixed zone material together with the old ballast and to provide a separating device by means of which old ballast can be separated from the removed material. In this case, the device may consist of two or more separation stages, wherein a first separation stage for separating coarse impurities, root system and clay chunks is formed, while a second separation stage is designed for separating old ballast. After separation of gravel remaining material, in particular sand, gravel, undersize and abrasion, then with in the treatment of old ballast (4 ') accumulating material and / or externally supplied material, especially virgin material, mixed and as a new, mechanically improved Substructure layer and / or layer protection layer and / or antifreeze layer and possibly a new additional intermediate layer between new, mechanically improved subgrade and level and / or frost protection layer installed again. In this way, a lot of finishing material can be reused. This saves new material and reduces the spoil.
Als Material zum Mischen mit nach Abtrennen von Altschotter verbleibendem wiedereinzubauenden Material kommen in Betracht Aufbereitungsrückstände von zu Recyclingschotter aufbereitetem Altschotter wie Splitte vom Schärfen von abgetrenntem Altschotter in einer Prallmühle, Über- und Unterkorn aus einem Körnungssieb für abgetrennten Altschotter und Siebrückstände aus einem Fingersieb, abgezweigter, nicht als Schotterbett wiedereingebauter, bevorzugt zumindest teilweise aufbereiteter und/oder in einem Kegelbrecher zerkleinerter Altschotter sowie von extern zugeführtes Material, insbesondere Neumaterial in flüssiger und/oder fester Form einschließlich zerkleinerter Neuschotter. Die hieraus hergestellte neue Unterbauschicht kann eine mechanisch verbesserte Schicht unter einer Planumsschutzschicht oder einer Frostschutzschicht sein, oder sie kann selbst eine Planums- oder Frostschutzschicht sein oder jeweils ein Teil davon. Es können auch zwei oder mehr mechanisch verbesserte Schichten auf die genannte Weise hergestellt werden, insbesondere mit unterschiedlicher Zusammensetzung der genannten Materialien. Die Schichten werden jeweils in bekannter Weise hergestellt, insbesondere durch Verdichten und Planieren. Abschließend wird auf den neuen Unterbau ein neues Schotterbett aufgebracht. Hierfür kann insbesondere der aufbereitete Altschotter und/oder Neuschotter verwendet werden.As material for mixing with residual material to be rebuilt after separation of old ballast, consideration is given to treatment residues of old ballast recycled to recycling ballast, such as chippings from the sharpening of separated old ballast in an impact mill, superimposed and undersize from a grain sieve for separated old ballast and sieve residues from a finger sieve, branched off, not rebuilt as ballast bed, preferably at least partially processed and / or comminuted in a cone crusher and externally supplied material, especially new material in liquid and / or solid form including crushed new ballast. The new subbing layer produced therefrom may be a mechanically improved layer under a topping protection layer or an antifreeze layer, or it may itself be a tarmac or antifreeze layer, or a part thereof in each case. It is also possible to produce two or more mechanically improved layers in the manner mentioned, in particular with different composition of the materials mentioned. The layers are each produced in a known manner, in particular by compaction and leveling. Finally, a new gravel bed is applied to the new substructure. For this purpose, in particular the processed old ballast and / or new ballast can be used.
Zur Aufbereitung des Altschotters wird dieser bevorzugt in einem Fingersieb gesiebt und/oder einer Prallmühle zum Schärfen zugeführt. Des weiteren kann der Altschotter in einem Körnungssieb gesiebt werden, um Über- und Unterkorn auszuscheiden und Schotterkörner der geforderten Größen herzustellen. Des weiteren kann der Altschotter gewaschen werden, um Verunreinigungen zu beseitigen. Ausscheidungen aus den genannten Einrichtungen können wie gesagt dem nach Abtrennen von Altschotter verbleibenden Material oder einem Teil davon zugemischt werden, bevor dieses als neue, mechanisch verbesserte Unterbauschicht und/oder Planumsschutzschicht und/oder Frostschutzschicht sowie eventuell eine neue zusätzliche Zwischenschicht zwischen neuer, mechanisch verbesserter Unterbauschicht und Planums- und/oder Frostschutzschicht oder Teil hiervon eingebaut wird.For the preparation of the old ballast, this is preferably sieved in a finger sieve and / or fed to an impact mill for sharpening. Furthermore, the old ballast can be sieved in a grain sieve to segregate oversize and undersize and to produce ballast grains of the required sizes. Furthermore, the old ballast can be washed to remove impurities. As mentioned, precipitates from said facilities can be admixed with the remaining material or a part thereof after separation of old ballast, before this as a new, mechanically improved base coat and / or layer protection layer and / or antifreeze layer and possibly a new additional intermediate layer between new, mechanically improved undercoat layer and subgrade and / or antifreeze layer or part thereof is incorporated.
Als erste Trennstufe kann beispielsweise ein Rollenrost verwendet werden, um Grobartikel, wie große Steine und Grasbüschel, abzutrennen. Auch kann ein Magnetabscheider vorgesehen sein, um Metallteile abzutrennen. Die Abzweigstelle (By-Pass) für nicht als Recyclingschotter wiedereinzubauenden Altschotter kann nach dieser Trennstufe angeordnet sein und/oder vor oder nach dem Waschsieb für den Altschotter. Als erste und zweite Aushubeinrichtung werden insbesondere Aushubketten verwendet, deren Aushubtiefe und -breite bevorzugt einstellbar sind. Soweit Material nicht wieder verwendbar ist oder wiederverwendet werden soll, wird dieses als Abraum abtransportiert.As a first separation step, for example, a roller grate can be used to separate Grobartikel, such as large stones and tufts of grass. Also, a magnetic separator may be provided to separate metal parts. The branching point (by-pass) for old ballast not to be rebuilt as recycling ballast can be arranged after this separation stage and / or before or after the washing screen for the old ballast. As the first and second excavating especially excavation chains are used, the excavation depth and width are preferably adjustable. As far as material is not reusable or is to be reused, this is removed as spoil.
Der Erfindungsgedanke, dass ausgebautes Mischzonenmaterial vor dem Wiedereinbau als neue Unterbauschicht mit bei der Aufbereitung von Altschotter anfallendem Material und/oder mit von extern zugeführtem Material, insbesondere Neumaterial, vermischt wird, wird auch unabhängig beansprucht. Es können dieselben Materialien zugemischt werden wie zuvor beschrieben.The idea of the invention that expanded mixed zone material is mixed prior to replacement as a new base coat with accumulating in the treatment of old ballast material and / or externally supplied material, in particular new material, is also claimed independently. The same materials can be mixed as described above.
Die Planumsschutzschicht und/oder die Frostschutzschicht können auch zwei- oder mehrlagig eingebaut werden. Dabei kann diese zwei- oder mehrlagige Schicht auch zumindest zeitweise anstelle einer neuen, mechanisch verbesserten Unterbauschicht eingebaut werden, und zwar insbesondere dann, wenn noch kein Aufbereitungsmaterial für eine solche neue, mechanisch verbesserte Unterbauschicht zur Verfügung steht, wie beispielsweise am Baustellenbeginn oder bei einer Bauunterbrechung, oder wenn aufgrund der Beschaffenheit des alten Gleisbetts kein geeignetes Material für eine neue, mechanisch verbesserte Unterbauschicht erhalten werden kann, wie beispielsweise bei Schlamm oder einer Lehmlinse. Vorteilhaft ist dabei der Einbau der zwei oder mehr Lagen in einem Arbeitsgang.The layer protection layer and / or the antifreeze layer can also be installed in two or more layers. In this case, this two-layer or multi-layer layer can also be installed at least temporarily instead of a new, mechanically improved substructure layer, especially if no treatment material for such a new, mechanically improved subgrade is available, such as at the start of construction or a construction interruption or if, due to the nature of the old track bed, no suitable material can be obtained for a new, mechanically improved subgrade, such as mud or a clay lens. The advantage here is the installation of two or more layers in a single operation.
Nach einer weiteren Ausgestaltung der Erfindung kann die Planumsschutzschicht oder die Frostschutzschicht auch nur aus neuem Material bestehen. Eine solche Schicht kann zusätzlich zu einer neuen, mechanisch verbesserten Unterbauschicht oder anstelle einer solchen eingebaut werden.

Der Systemskizze ist die bevorzugte Durchführung des erfindungsgemäßen Verfahrens mit unterschiedlichen Varianten entnehmbar, wobei
Das nach Abtrennen der Feinstoffe verbleibende Material, also insbesondere Schotter, wird dann einem Fingersieb als dritte Trennstufe zugeführt. Hier können noch feinere Verunreinigungen entfernt und ebenfalls über Linie (1) wieder verwendet werden. Vor dem Fingersieb kann ein Bypass zu einem Kegelbrecher vorgesehen sein, mit dem ein Teil des abgetrennten Schotters gebrochen und der Wiederverwendung für eine neue Unterbauschicht zugeführt wird, wie dies mit Linie (2) dargestellt ist. Der durch das Fingersieb abgetrennte Altschotter kann dann entweder direkt als Recycling (RC-) Schotter wiederverwendet werden oder einer Prallmühle zugeführt werden, in welcher der Schotter geschärft wird. Reststoffe der Prallmühle dienen wieder als Zumischmaterial für die neue Unterbauschicht gemäß Linie (1) oder (2).The material remaining after separation of the fines, ie in particular ballast, is then fed to a finger screen as the third separation stage. Here even finer impurities can be removed and also reused via line (1). A bypass to a cone crusher may be provided in front of the finger screen to break a portion of the separated ballast and reuse it for a new subheading layer, as shown by line (2). The old gravel separated by the finger sieve can then either be reused directly as recycling (RC) gravel or fed to an impact crusher, in which the gravel is sharpened. Residues of the impact crusher serve again as admixing material for the new substructure layer according to line (1) or (2).
Der in der Prallmühle geschärfte Schotter wird sodann einem Körnungssieb zugeführt, um Schotter der gewünschten Körnung zu erhalten. Über- und Unterkorn aus dem Körnungssieb wird wiederrum über Linie (1) oder (2) als Zumischmaterial für die neue Unterbauschicht verwendet. Der gesiebte Schotter wird einem Waschsieb zugeführt, wobei vor oder nach dem Waschsieb ein Bypass zu einem Kegelbrecher vorgesehen sein kann. Abgetrennter und gebrochener Altschotter wird wiederrum über Linie (2) als Zumischmaterial für eine neue Unterbauschicht eingesetzt. Der übrige gereinigte Schotter wird als RC-Schotter wiederverwendet. Dem in den dargestellten Kegelbrechern gebrochenen Altschotter können zudem, wie dargestellt, feste oder flüssige, insbesondere chemische Zusatzstoffe zugeführt werden, um ebenfalls als Zumischmaterial für die neue Unterbauschicht eingesetzt zu werden.The ballast sharpened in the impact mill is then fed to a grit screen to obtain ballast of the desired grain size. Over- and undersize grain from the grain sieve is again used via line (1) or (2) as Zumischmaterial for the new subheading.
