Abstract

1. A cutter head for advancing prefabricated concrete pipes for the construction of galleries or tunnels, the concrete pipes being advanced in succession in the form of a continuous pipeline by a feed device from a pressure pit to a trench lined with vertical timbering panels and an uncleared part of the trench is cut by a tubular cutter head and the cut material is removed by an excavator, characterised in that the upper surface of the cutter head (2) is formed with an excavated-earth openning (12).

Description

Die Erfindung betrifft einen Schneidkopf für den Vortrieb vorgefertigter Betonrohre zur Herstellung von Stollen oder Tunneln, wobei die Betonrohre von einer Preßgrube aus mittels einer Vortriebseinrichtung aufeinanderfolgend in einem mit lotrechten Verbautafeln ausgerüsteten Graben als zusammenhängender Rohrstrang vorgetrieben werden und ein nicht freigelegter Teil des Grabens durch einen rohrförmigen Schneidkopf angeschnitten wird.The invention relates to a cutting head for the driving of prefabricated concrete pipes for the production of tunnels or tunnels, the concrete pipes being driven successively from a press pit by means of a driving device in a trench equipped with vertical sheeting panels as a coherent pipe string and an unexposed part of the trench by a tubular one Cutting head is cut.

Beim Herstellen von Stollen oder Tunneln aus vorgefertigten Betonrohren wird in Abhängigkeit von der Mächtigkeit des Erdreichs über den Betonrohren entweder in geschlossener oder offener Bauweise gearbeitet. Bei einer Mächtigkeit bis zum zwei- bis dreifachen Rohrdurchmesser wird häufig die offene Grabenbauweise angewendet.Etonrohren in the manufacture of studs or tunnels from prefabricated B of the soil over the concrete pipes in either a closed or open construction is carried out in dependence on the thickness. With a thickness of up to two to three times the pipe diameter, the open trench construction is often used.

Bei der bekannten offenen Grabenbauweise wird ein relativ breiter Graben ausgehoben, wobei entweder der natürliche Böschungswinkel zu berücksichtigen ist, oder die Grabenwandung durch zusätzliche Ausbauten, beispielsweise lotrechte Verbauplatten, gesichert werden muß. Die Rohre werden mittels eines Kranes, der auf einer neben dem Graben erforderlichen Bahn verfährt, von oben in den Graben gelegt. Nach dem Eimlegen der Rohre wird der Graben ausgefüllt und das Gelände eingeebnet.In the known open trench construction, a relatively wide trench is excavated, whereby either the natural slope angle has to be taken into account or the trench wall has to be secured by additional extensions, for example vertical sheeting plates. The pipes are placed in the trench from above by means of a crane, which travels on a path that is required next to the trench. After laying the pipes, the trench is filled in and the terrain is leveled.

Um die Platzerfordernisse zu verringern und die Verlegeleistung zu steigern, ist aus der DE-AS 16 58 772 bekannt geworden, Betonrohre von einer Preßgrube aus mittels einer hydraulischen Vortriebseinrichtung aufeinanderfolgend in einem im Querschnitt etwa V-förmigen Graben als zusasmmenhängenden Rohrstrang vorzutreiben, wobei ein nicht freigelegter Teil des Grabens durch den Schneidkopf angeschnitten wird. Diese hydraulische Vortriebsweise in einem offenen Graben mit natürlichem Böschungswinkel hat sich dort bewährt, wo ein genügend breiter Raum für den im Querschnitt V-förmigen Graben zur Verfügung steht. Um einen Vortrieb auch bei schmalen Bauflächenbreiten zu ermöglichen, ist aus der DE-P 33 14 813 bekannt, die Breite des mit lotrechten Verbautafeln ausgerüsteten Grabens gleich oder kleiner als den Außendurchmesser der Betonrohre zu gestalten, wobei die Verbautafeln auf jeder Grabenseite bei einer dem Außendurchmesser entsprechenden Breite des Grabens eine bis zu den Seitenlinien der Betonrohre reichende, oder bei einer geringeren Breite des Grabens eine bis knapp über die Betonrohre reichende Bautiefe erhalten. Bei dieser offenen Bauweise bildet sich vor dem Schneidkopf eine Endböschung, deren Böschungswinkel etwa an der unteren Stelle des Schneidkopfes ansetzt. Beim Vortrieb schneidet der Schneidkopf auch die Endböschung an. Das vom Schneidkopf angeschnittene Material muß jedoch nach vorn auf die Endböschung geschaufelt oder geschoben werden, damit es vor dem Schneidkopf von einem Bagger ausgehoben werden kann..In order to reduce the space requirements and to increase the laying performance, it has become known from DE-AS 16 58 772 to advance concrete pipes from a press pit by means of a hydraulic jacking device in succession in a trench of approximately V-shaped cross-section as a coherent pipe string, one not exposed part of the trench is cut by the cutting head. This hydraulic method of driving in an open trench with a natural slope angle has proven itself where there is sufficient space for the trench, which is V-shaped in cross section. In order to enable jacking even with narrow construction area widths, it is known from DE-P 33 14 813 to design the width of the trench equipped with vertical sheeting panels to be equal to or smaller than the outside diameter of the concrete pipes, with the sheeting panels on each side of the trench at one of the outside diameter receive a corresponding width of the trench reaching to the side lines of the concrete pipes, or in the case of a smaller width of the trench a structural depth reaching just above the concrete pipes. With this open design, an end slope is formed in front of the cutting head, the slope angle of which starts approximately at the lower point of the cutting head. When driving, the cutting head also cuts the end slope. However, the material cut by the cutting head must be shoveled or pushed forward onto the end slope so that it can be excavated by an excavator in front of the cutting head.

Anderseits ist aus der DE-OS 23 22 468 ein Schneidkopf bekannt, der mit einem von der Sohle bis zur Kopflinie schräg verlaufenden Verdrängerboden ausgerüstet ist, der in geschlossener Vortriebsweise durch das Erdreich gepreßt wird und dabei das Erdreich maulwurfartig nach oben drückt. Für eine offene Vortriebsweise mit Baggeraushub ist dieser Schneidkopf nicht geeignet, weil ihm ein Raum fehlt, in den das angeschnittene Erdreich gedrängt wird und aus dem es mittels eines Baggers ausgehoben werden kann.On the other hand, a cutting head is known from DE-OS 23 22 468, which is equipped with a displacement base which runs obliquely from the sole to the head line and which is pressed through the ground in closed driving mode and thereby presses the ground up like a mole. This cutting head is not suitable for an open method of excavation with excavator excavation because it there is no room into which the cut soil is pushed and from which it can be excavated using an excavator.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, einen Schneidkopf der gattungsgemäßen Art derart auszubilden, daß das vom Schneidkopf angeschnittene Material nicht mehr nach vorn auf die Endböschung geschaufelt oder geschoben werden muß, um von einem Bagger ausgehoben werden zu können.In contrast, the invention has for its object to form a cutting head of the generic type such that the material cut by the cutting head no longer has to be shoveled or pushed forward onto the end slope in order to be excavated by an excavator.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Schneidkopf an seinem oberen Mantelteil mit einer Aushuböffnung versehen ist, durch welche das angeschnittene Material unmittelbar aus dem Schneidkopf von einem Aushubgerät ausgeräumt werden kann. Die bisherige Schaufel- oder Schiebearbeit und das hierfür erforderliche Gerät und Personal kann entfallen.This object is achieved in that the cutting head is provided on its upper casing part with an excavation opening through which the cut material can be cleared directly from the cutting head by an excavation device. The previous shoveling or pushing work and the equipment and personnel required for this can be omitted.

Besonders günstige Arbeitsverhältnisse werden gechaffen, wenn die Aushuböffnung in ihrer Breite knapp der lichten Grabenbreite entspricht und sich über die gesamte Länge des Schneidkopfes erstreckt. Vorzugsweise ist der Schneidkopf mit einer die Aushuböffnung abdekkenden und lösbar am Rand der Aushuböffnung befestigbaren Haube versehen. Der Schneidkopf kann daher mit aufgesetzter Haube auch für die geschlossene Bauweise verwendet werden. Der Austausch eines offenen Schneidkopfes gegen einen geschlossenen, oder umgekehrt, ist bei wechselnder Bauweise, wie sie in der Praxis vorkommt, nicht mehr erforderlich, sondern der erfindungsgemäß ausgebildete Schneidkopf kann einfach und schnell umgerüstet werden.Particularly favorable employment relationships are created when the width of the excavation opening is just under the clear trench width and extends over the entire length of the cutting head. The cutting head is preferably provided with a hood that covers the excavation opening and can be detachably attached to the edge of the excavation opening. The cutting head can therefore also be used for the closed design with the hood attached. The exchange of an open cutting head for a closed, or vice versa, is no longer necessary in the case of a changing construction, as occurs in practice, but the cutting head designed according to the invention can be converted easily and quickly.

Um das Eindringen von eventuell anstehendem Grundwasser in den vorgepreßten Rohrstrang zu verhindern, ist zweckmäßig im Schneidkopf eine Schottenwand lösbar angeordnet, die mit einer von der unteren Mantellinie am vorderen Ende ausgehenden und keilförmig zum rückwärtigen Ende hin bis etwa zum halben Durchmesser ansteigenden Leitplatte versehen ist.In order to prevent any groundwater from entering the pre-pressed pipe string, a partition wall is expediently arranged in the cutting head, which is provided with a guide plate starting from the lower surface line at the front end and rising in a wedge shape towards the rear end up to approximately half the diameter.

Die Erfindung ist in der Zeichnung beispielsweise dargestellt. Es zeigt:

  • Fig. 1 einen lotrechten Längsschnitt durch eine Rohrvortriebsstrecke,
  • Fig. 2 den Gegenstand der Fig. 1 in einer Ansicht auf das vordere Ende des Schneidkopfes in einem größeren Maßstab,
  • Fig. 3 den Gegenstand der Fig. 2 in einem Längsschnitt,
  • Fig. 4 eine dem Schneidkopf der Fig. 2 zugeordnete Haube in einer Vorderansicht und
  • Fig. 5 den Gegenstand der Fig. 4 in einem mittleren Längsschnitt.
The invention is shown in the drawing, for example. It shows:
  • 1 is a vertical longitudinal section through a pipe jacking section,
  • 2 shows the subject of FIG. 1 in a view of the front end of the cutting head on a larger scale,
  • 3 shows the object of FIG. 2 in a longitudinal section,
  • Fig. 4 is a hood associated with the cutting head of Fig. 2 in a front view
  • Fig. 5 shows the subject of Fig. 4 in a middle longitudinal section.

Bei der in Fig. 1 dargestellten Ausführung werden mehrere Betonrohre 1 von einer Preßgrube 8 aus mittels einer hydraulischen Vortriebseinrichtung 9 an der Sohle eines Grabens 3 vorgedrückt, wobei der am vorderen Ende befindliche steuerbare Schneidkopf 2 den nicht freigelegten Tei des Grabens 3 anschneidet. Die Preßgrube 9 kann in üblicher Weise mit einer Vorpreßschiene 10 und einem Widerlager 11 für die hydraulische Vortriebseinrichtung 9 ausgerüstet sein. Der Schneidkopf 2 ist in üblicher Weise doppelwandig ausgebildet, mit Steuerzylindern ausgerüstet und liegt unter Zwischenlage eines Druckrings 7 gegen das Stirnende des vorderen Betonrohres 1 an.In the embodiment shown in FIG. 1, a plurality of concrete pipes 1 are pressed forward from a press pit 8 by means of a hydraulic jacking device 9 on the bottom of a trench 3, the controllable cutting head 2 located at the front end cutting the unexposed part of the trench 3. The press pit 9 can be equipped in the usual way with a pre-press rail 10 and an abutment 11 for the hydraulic jacking device 9. The cutting head 2 is double-walled in the usual way, equipped with control cylinders and lies with the interposition of a pressure ring 7 against the front end of the front concrete pipe 1.

Am Kopfende des Rohrstranges, vor dem Schneidkopf 2, erfolgt der Aushub des Grabens 3 mittels eines Grabenbaggers o. dgl. Nach Aushub eines geeigneten Profils werden die Grabenwände durch Verbautafeln 4 gesichert. Vorzugsweise werden Verbaueinheiten verwendet, die aus zwei parallel angeordneten und durch Spreizorgane 5 in dem vorgesehenen Abstand gehaltenen Verbautafeln 4 bestehen. Ist ein Stück des Grabens mit einer entsprechenden Breite ausgehoben worden, wird die Verbaueinheit mit dem Bagger eingesetzt und, gegebenenfalls nach weiterem Aushub, bis zu der vorgesehenen Einbautiefe nach unten gedrückt.At the head end of the pipe string, in front of the cutting head 2, the trench 3 is excavated by means of a trench excavator or the like. After excavating a suitable profile, the trench walls are secured by sheeting panels 4. Shoring units are preferably used which consist of two shoring panels 4 arranged in parallel and held at the intended distance by expansion elements 5. If a piece of the trench has been excavated with a corresponding width, the shoring unit is inserted with the excavator and, if necessary after further excavation, pressed down to the intended installation depth.

Wie insbesondere die Fig. 2 bis 4 zeigen, ist der Schneidkopf 2 an seinem oberen Mantelteil mit einer Aushuböffnung 12 versehen, durch welche das vom Schneidkopf 2 angeschnittene Material 6 mittels eines Aushubgerätes bzw. eines Baggers unmittelbar aus dem Schneidkopf 2 nach oben ausgehoben werden kann. Die Aushuböffnung 12 muß daher zumindest so groß sein, daß der Greifer des Aushubgerätes hindurchpaßt. Bei dem dargestellten Ausführungsbeispiel entspricht die Breite der Aushuböffnung 12 knapp der lichten Breite des Grabens 3, und ihre Länge erstreckt sich über die gesamte Länge des Schneidkopfes 2, der somit eine trogförmige Gestalt aufweist.As shown in FIGS. 2 to 4 in particular, the cutting head 2 is provided on its upper casing part with an excavation opening 12, through which the material 6 cut by the cutting head 2 can be lifted directly upwards out of the cutting head 2 by means of an excavation device or an excavator . The excavation opening 12 must therefore be at least large enough that the gripper of the excavation device fits through. In the illustrated embodiment, the width of the excavation opening 12 corresponds to the clear width of the trench 3, and its length extends over the entire length of the cutting head 2, which thus has a trough-shaped shape.

Der Schneidkopf 2 ist mit einer die Aushuböffnung 12 abdeckenden Haube 13 versehen. Diese entspricht dem doppelwandigen Rohrprofil des Schneidkopfes 2 und ist an ihren beiden seitlichen Rändern lösbar am Schneidkopf 2 zu befestigen. In den Fig. 4 und 5 ist die Haube 13 zur zeichnerischen Vereinfachung nur einwandig dargestellt; zwischen der vorhandenen Doppelwand können, ebenso wie beim Schneidkopf 2, Steuerzylinder angeordnet sein. Der Lagerung dienen beispielsweise an den seitlichen Rändern der Aushuböffnung 12 angebrachte Konsolen 14, auf denen sich entsprechend ausgebildete Seitenschenkel 15 der Haube 13 abstützen. Zur lösbaren Befestigung sind die Konsolen 14 und Seitenschenkel 15 z. B. mit Bohrungen 16 für Schraubbolzen o. dgl. versehen. Der Schneidkopf 2 kann mit aufgesetzter Haube 13 für die geschlossene und mit abgenommener Haube 13 für die offene Bauweise verwendet werden.The cutting head 2 is provided with a hood 13 covering the excavation opening 12. This corresponds to the double-walled tubular profile of the cutting head 2 and can be detachably attached to the cutting head 2 at its two lateral edges. 4 and 5, the hood 13 is shown for the sake of simplicity only single-walled; control cylinders can be arranged between the existing double wall, as with the cutting head 2. Storage is used, for example, on the lateral edges of the excavation opening 12, consoles 14, on which there are appropriately designed side legs 15 of the hood 13 support. For releasable attachment, the brackets 14 and side legs 15 z. B. provided with holes 16 for bolts or the like. The cutting head 2 can be used with the hood 13 attached for the closed construction and with the hood 13 removed for the open construction.

Für den Fall, daß im Graben Grundwasser ansteht, kann dessen Eindringen in den Rohrstrang durch eine im Schneidkopf 2 lösbar befestigte Schottenwand 17 verhindert werden. Dieser ist eine Leitplatte 18 zugeordnet, die von der unteren Mantellinie am vorderen Ende des Schneidkopfes 2 ausgehend keilförmig zur Schottenwand 17 hin bis etwa zum halben Durchmesser ansteigt.In the event that groundwater is present in the trench, its penetration into the pipe string can be prevented by a bulkhead wall 17 which is detachably fastened in the cutting head 2. This is assigned a guide plate 18 which, starting from the lower surface line at the front end of the cutting head 2, rises in a wedge shape towards the bulkhead wall 17 up to approximately half the diameter.
