Abstract

The invention relates to a method and a device for introducing heading supports (1) in parallel to the heading of a tunnel (1) by means of a selective cut heading machine (2). According to the invention, facing mats (18, 19) in the form of rolled mats (20, 21) are provided downstream of the cutting tool (3) of the selective cut heading machine (2) in two traverse planes (14, 15) that are arranged in tandem in the longitudinal direction of the heading in a manner as to be off-set from each other on the periphery. The facing mats (18, 19) are unrolled, simultaneously to the heading, in the longitudinal direction of the heading so as to overlap laterally and are instantly fixed in the rock. Once the facing mats (18, 19) have been entirely unrolled, the working steps are successively repeated with new facing mats (18, 19) that adjoin the facing mats (18, 19) already laid in accordance with the length of the heading. The heading support (7) is introduced at a distance to the cutting tool (3) while fixing the facing mats (18, 19).

Description

Verfahren und Vorrichtung zum Einbringen eines Streckenausbaus Method and device for introducing a route construction
Die Erfindung betrifft einerseits ein Verfahren zum Einbringen eines Streckenausbaus parallel zum Vortrieb einer Strecke mittels einer Teilschnittmaschine gemäß den Merkmalen im Oberbegriff des Anspruchs 1.On the one hand, the invention relates to a method for introducing a route extension parallel to the propulsion of a route by means of a roadholding machine according to the features in the preamble of claim 1.
Andererseits richtet sich die Erfindung auf eine Vorrichtung zur Durchführung des Verfahrens entsprechend den Merkmalen im Oberbegriff des Anspruchs 6.On the other hand, the invention is directed to an apparatus for carrying out the method according to the features in the preamble of claim 6.
Es ist im Stand der Technik bekannt, den Vortrieb einer untertägigen Strecke oder eines Tunnels mit Hilfe einer Teilschnittmaschine unabhängig vom Ausbau dieser aufgefahrenen Strecke bzw. dieses Tunnels durchzuführen (DE-AS 23 61 227 oder DE-PS 26 46 496).It is known in the art to carry out the driving of an underground route or a tunnel with the help of a roadheader independently of the expansion of this ascended route or this tunnel (DE-AS 23 61 227 or DE-PS 26 46 496).
Die Vortriebsleistung beim Auffahren einer Strecke unter Einsatz einer Teilschnittmaschine wird sowohl beim Bogenausbau als auch beim Türstockausbau weitgehend durch die Ausbauleistung bestimmt. In diesem Zusammenhang konnte bislang die reale Schneidleistung einer Teilschnittmaschine nicht voll ausgenutzt werden, obwohl eine Parallelisierung des Schneidvorgangs mit dem Ausbauvorgang erfolgt. Ein Grund hierfür ist, dass durch das Verfahren und Ausrichten der Teilschnittmaschine nicht nur der Schneid-, sondern auch der Ausbauvorgang ablaufbedingt unterbrochen werden. Ferner wird die Stillstandszeit der Teilschnittmaschine durch den Vorgang "Verzug einbauen" verlängert.The propulsive power when approaching a track using a roadheader is determined largely by the expansion performance both when sheet removal and the door frame removal. In this context, so far, the real cutting performance of a roadheader could not be fully exploited, although a parallelization of the cutting process takes place with the removal process. One reason for this is that not only the cutting, but also the removal process can be interrupted due to the process and alignment of the roadheader. Furthermore, the downtime of the roadheader is extended by the process "install delay".
Der Erfindung liegt - ausgehend vom Stand der Technik - die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zum Einbringen eines Streckenausbaus parallel zum Vortrieb einer Strecke mittels einer Teilschnittmaschine vorzuschlagen, bei welchen die Stillstandszeit der Teilschnittmaschine im Prinzip auf Wartungs- und Instandhaltungsmaßnahmen beschränkt werden kann. Was die Lösung des verfahrensmäßigen Teils dieser Aufgabe anlangt, so wird diese in den kennzeichnenden Merkmalen des Anspruchs 1 erblickt.The invention is - based on the prior art - the object of proposing a method and apparatus for introducing a route extension parallel to the propulsion of a route by means of a roadheader, in which the downtime of the roadheader can be limited in principle to maintenance and repair. As to the solution of the procedural part of this task, it is seen in the characterizing features of claim 1.
Kern der erfindungsgemäßen Maßnahme bildet der Sachverhalt, dass direkt hinter dem Schneidwerkzeug der Teilschnittmaschine der zum einwandfreien Ausbau einer Strecke notwendige Verzug eingebracht und am freigelegten Gebirge quasi in Form einer Schutzhülle justiert wird. Auf diese Weise kann dann nachfolgend im Abstand zum Schneidwerkzeug der jeweilige Streckenausbau unter Fixierung des Verzugs eingebracht werden.The core of the measure according to the invention is the fact that directly behind the cutting tool of the roadheader the necessary for proper expansion of a route delay introduced and adjusted on the exposed mountains quasi in the form of a protective cover. In this way can then be introduced to fix the delay at the distance to the cutting tool of the respective route extension.
Dazu werden direkt hinter dem Schneidwerkzeug der Teilschnittmaschine in zwei in Streckenlängsrichtung hintereinander liegenden Querebenen mehrere Verzugmatten in Form von Mattenrollen bereitgestellt. Die Mattenrollen jeder Querebene werden in Umfangsrichtung der Strecke so mit Abstand einander zugeordnet, dass beim Abrollen die Verzugmatten in der 2. Querebene die Verzugmatten der der Ortsbrust näher liegenden 1. Querebene randseitig überlappen. Damit wird die gesamte durch die Teilschnittmaschine freigelegte Mantelfläche der Strecke abgedeckt.For this purpose, several delay mats in the form of mat rolls are provided directly behind the cutting tool of the roadheader in two transverse planes one behind the other in the longitudinal direction of the track. The mat rolls of each transverse plane are assigned to each other in the circumferential direction of the distance so that when rolling the default mats in the second transverse plane overlap the default mats of the 1st transverse plane closer to the working face edge. This covers the entire lateral surface of the track exposed by the roadheader.
Die Überlappung der Verzugmatten in Umfangsrichtung wird gemäß der Erfindung so bemessen, dass immer ein ausreichend großer Puffer vorhanden ist, wenn z.B. durch geotechnische Unregelmäßigkeiten aufgetretene Vergrößerungen der Mantelflächen ein unplanmäßiger Nachfall gelockerten Gebirges ausgelöst wurde.The overlap of the drafting mats in the circumferential direction is dimensioned according to the invention so that there is always a sufficiently large buffer, if e.g. By geotechnical irregularities occurred enlargements of the lateral surfaces of an unscheduled Nachfall loosened mountains was triggered.
Nach dem Abrollen der Verzugmatten, welche beispielsweise eine Länge von etwa 20 m und Breiten von 1 ,5 m bis 2 m aufweisen können, werden wiederum in zwei in Streckenlängsrichtung aufeinander folgenden Querebenen in umfangsseitiger Versetzung weitere Verzugmatten in Form von Mantelrollen mit den bereits verlegten Verzugmatten verbunden und nach dem Abrollen sofort an der Mantelfläche des Gebirges justiert.After the unwinding of the delay mats, which may have, for example, a length of about 20 m and widths of 1, 5 m to 2 m, in turn in two longitudinal direction in successive transverse planes in circumferential displacement more default mats in the form of sheath rolls with the already installed default mats connected and adjusted immediately after rolling on the lateral surface of the mountains.
Die Erfindung erlaubt dann anschließend die parallelisierte Ausbauarbeit mit herkömmlichem Bogen- oder Türstockausbau und Vollhinterfüllung, mit Spritzbeton oder Ankerspritzbeton sowie mit selbstschreitenden Ausbaueinheiten, wie z.B. Schutzdach und Schalwagen, durchzuführen, ohne dass diese Ausbauarbeiten einen Stillstand der Teilschnittmaschine verlangen. Entsprechend den Merkmalen des Anspruchs 2 ist es besonders vorteilhaft, dass die abgerollten Verzugmatten durch einen selbstständig verlagerbaren Verzugmanipulator am Gebirge justiert werden. Dieser Verzugmanipulator trägt mithin Sorge dafür, dass die Verzugmatten einwandfrei am Gebirge anliegen, so dass anschließend der jeweilige Streckenausbau problemlos eingebracht werden kann.The invention then then allows the parallelized finishing work with conventional bow or door frame and full backfilling, with shotcrete or Ankerspritzbeton and self-extending expansion units, such as protective roof and Schalwagen to perform without this expansion work require a stoppage of the roadheader. According to the features of claim 2, it is particularly advantageous that the unwound default mats are adjusted by an independently displaceable warping manipulator on the mountains. This distortion manipulator thus ensures that the delay mats properly rest against the mountains, so that then the respective route expansion can be easily introduced.
Der Verzugmanipulator kann darüber hinaus in vorteilhafter Weise dazu genutzt werden, den Schneidraum oberhalb des Schneidwerkzeugs abzusichern, wenn z.B. planmäßige Wartungs- oder Instandhaltungsmaßnahmen an der Teilschnittmaschine durchgeführt werden müssen.The draft manipulator can also be advantageously used to secure the cutting space above the cutting tool when e.g. scheduled maintenance or repairs must be performed on the roadheader.
Nach den Merkmalen des Anspruchs 3 ist es von Vorteil, dass die bereits verlegten Verzugmatten, die gegebenenfalls auch schon durch einen Streckenausbau unterfangen sein können, mit den neuen abgerollten Verzugmatten sich endseitig überlappend gekoppelt werden. Eine solche Kopplung kann nur durch Überlappung oder auch durch einen direkten fügetechnischen Anschluss von in Streckenlängsrichtung aufeinander folgenden Verzugmatten erfolgen.According to the features of claim 3, it is advantageous that the already installed default mats, which may possibly already be underpinned by a track extension, with the new unwound default mats are coupled overlapping end. Such a coupling can only be done by overlapping or by a direct technical joining of successive delay mats in the longitudinal direction.
Entsprechend den Merkmalen des Anspruchs 4 können die Verzugmatten durch einen Ankerausbau am Gebirge festgelegt werden.According to the features of claim 4, the default mats can be determined by an anchor extension on the mountains.
Denkbar ist es nach den Merkmalen des Anspruchs 5 aber auch, dass die Verzugmatten durch Ausbaurahmen (Bogenausbau, Türstockausbau) lagefixiert werden.It is conceivable according to the features of claim 5 but also that the default mats are fixed in position by expansion frame (sheet removal, door frame removal).
Unabhängig davon, ob nun ein Ankerausbau oder ein Streckenausbau mit Ausbaurahmen zum Einsatz gelangt, können diese Ausbaumaßnahmen wiederum mit unabhängig von der Teilschnittmaschine in Streckenlängsrichtung verlagerbaren Arbeitsbühnen durchgeführt werden.Regardless of whether an armature removal or a track extension with expansion frame is used, these expansion measures can in turn be carried out independently of the roadheader in the longitudinal direction displaceable work platforms.
Die Lösung des gegenständlichen Teils der der Erfindung zugrunde liegenden Aufgabe wird in den kennzeichnenden Merkmalen des Anspruchs 6 erblickt.The solution of the subject part of the invention is based task is seen in the characterizing features of claim 6.
Diese erfindungsgemäße Vorrichtung kennzeichnet sich durch einen unabhängig von der Teilschnittmaschine in Streckenlängsrichtung verlagerbaren Verzugmanipulator. Dieser Verzugmanipulator weist in zwei in Streckenlängsrichtung hintereinander liegenden Querebenen in Umfangsrichtung zueinander versetzt angeordnete Mattenmagazine zur Aufnahme der Verzugmatten in Form von Mattenrollen auf. Hierbei sind die Mattenmagazine in einer 1. Querebene zu den Mattenmagazinen in der anderen 2. Querebene auf Lücke gesetzt.This device according to the invention is characterized by a distortion manipulator which can be displaced independently of the roadheader in the longitudinal direction of the track. This distortion manipulator has in two in the longitudinal direction longitudinally one behind the other lying transverse planes in the circumferential direction offset from one another arranged matte magazines for receiving the default mats in the form of mat rolls. Here, the mat magazines are placed in a first transverse plane to the mat magazines in the other 2nd transverse plane to gap.
Der Verzugmanipulator folgt unmittelbar dem Schneidwerkzeug der Teilschnittmaschine. Die Verzugmatten entrollen sich aus den Mattenmagazinen und werden sofort durch den Verzugmanipulator an der freigelegten Mantelfläche des Gebirges justiert. Auf diese Weise wird ein umfangsseitig gesicherter Bereich in Form einer Schutzhülle geschaffen, der hinter dem Verzugmanipulator dazu genutzt werden kann, um den jeweiligen Streckenausbau unter Fixierung der Verzugmatten am Gebirge ordnungsgemäß einzubringen.The default manipulator follows immediately the cutting tool of the roadheader. The delay mats unroll from the mat magazines and are adjusted immediately by the draft manipulator on the exposed lateral surface of the mountains. In this way, a circumferentially secured area in the form of a protective cover is created, which can be used behind the drafting manipulator to duly bring in the respective route construction while fixing the default mats on mountains.
Es ist nach den Merkmalen des Anspruchs 7 zweckmäßig, dass die Mattenmagazine mit Rückhalte- bzw. Spannautomaten für die Mattenrollen versehen sind.It is expedient according to the features of claim 7 that the mat magazines are provided with retaining or clamping machines for the mat rolls.
Um die Verzugmatten ordnungsgemäß an der Mantelfläche des Gebirges platzieren und justieren zu können, ist gemäß Anspruch 8 vorgesehen, dass der Verzugmanipulator eine Höhensteuerung aufweist. Mit Hilfe der Höhensteuerung wird beim Abrollen im mittleren Längen bereich jedes Matten magazins ein bestimmter Abstand der Verzugmatten zur M antelfläche d es Gebirges erreicht. Dadurch, d ass die Verzugmatten sich z.B. beim Bogenausbau in Form einer Sehne relativ zur Mantelfläche erstrecken, wird dann in Verbindung mit den Rückhalte- und Spannautomaten jedes Mattenmagazins eine bewusste Vorspannkraft für das spätere Einbringen des Streckenausbaus aufgebaut.In order to properly place and adjust the drafting mats on the lateral surface of the mountains, it is provided according to claim 8, that the drafting manipulator has a height control. With the help of the height control is achieved when rolling in the middle length range of each mats magazines a certain distance of the default mats to M nel surface d it mountains. Thereby, the default mats are e.g. When arch expansion in the form of a chord extend relative to the lateral surface, a deliberate biasing force for the subsequent introduction of the track construction is then built in conjunction with the retention and clamping machines each mat magazine.
Der Höhensteuerung sind nach Anspruch 9 Abstandssensoren in Form von z.B. Lasersensoren zugeordnet. Mit Hilfe dieser Abstandssensoren kann ein technisch machbarer Minimalabstand der Verzugmatten zur Mantelfläche des Gebirges sicher eingehalten werden.The height control are according to claim 9 distance sensors in the form of e.g. Associated with laser sensors. With the help of these distance sensors a technically feasible minimum distance of the delay mats to the lateral surface of the mountains can be safely met.
Wenn gemäß den Merkmalen des Anspruchs 10 der Verzugmanipulator an mindestens einer hängend verlegten Fahrschiene entlang verlagert wird, ist die Höhensteuerung vorzugsweise an einem Ausleger des Verzugmanipulators vorgesehen.If, according to the features of claim 10, the drafting manipulator is displaced along at least one suspended rail, the Height control preferably provided on a boom of the default manipulator.
Bei einem Verzugmanipulator, der entsprechend Anspruch 11 auf der Streckensohle und/oder am Streckenstoß geführt ist, kann der Abstand der abgerollten Verzugmatten zur Mantelfläche des Gebirges mit insbesondere hydraulisch beaufschlagbaren Zylindern erreicht werden.In a default manipulator, which is guided according to claim 11 on the route sole and / or the distance impact, the distance of the unwound default mats can be achieved to the lateral surface of the mountains with particular hydraulically loadable cylinders.
