Description
Tübbing mit selbstverriegelnden Verbindungs-Elementen für den Ausbau von Tunneln und Schächten Gegenstand der Erfindung ist ein Tübbing vornehmlich aus Stahlbeton-für den Ausbau von Tunneln und Schächten, der an den Seitenflächen der Ringfugen und/oder der Stoßfugen mit Verbindungs-Elementen versehen ist, durch die die Tübbings ohne manuelle Arbeit (wie z.B. Verschrauben oder Verspannen) - vorzugsweise unter Ausnutzung der vorhandenen Schildeinrichtungen wie Tu'bbing-Erektor und Vorschubpressen - schon während des Versetzvorganges so miteinander verbunden werden, dal> die neu versetzten Tübbings sicher gehalten sind und in den Tübbingfugen der gewünschte Anpreßdruck herrscht.Tubbing with self-locking connecting elements for expansion of tunnels and shafts The subject matter of the invention is primarily a segment Reinforced concrete-for the construction of tunnels and shafts on the side surfaces of the Annular joints and / or the butt joints is provided with connecting elements through which the segments without manual work (e.g. screwing or bracing) - preferably using the existing shield devices such as tubbing erectors and feed presses - are connected to one another during the relocation process in such a way that> the newly relocated segments are securely held and in the segment joints the desired There is contact pressure.
Tübbings aus Stahlbeton, Stahl oder Gußeisen werden vorwiegend mittels Ankern, Schrauben oder Vorspanngliedern miteinander verbunden. Bekannt sind außerdem keilförmige und/oder mit Nut und Feder versehene Tübbings, mit denen eine gewisse Verriegelungswirvorwiegend kung erzielt werden kann, die jedoch te Auskleidungen in kurzfristig standfestem Gebirge vorgesehen sind. Diese Tübbings haben zudem. oft eine für den Vortrieb ungünstige Form und sind in ihrer Wirkungsweise nicht zufriedenstellend. Besonders aber die verschraubten und verspannten Tiibbings haben den Nachteil, daß bei der Herstellung kostenaufwendige Vorkehrungen für Aussparungen, Kassetten, Paßsitze usw. getroffen werden müssen.Tubbings made of reinforced concrete, steel or cast iron are predominantly made by means of Anchors, screws or tendons connected to one another. Are also known wedge-shaped and / or tongue and groove tubbings with which a certain Interlocking can mainly be achieved, but the linings are provided in short-term stable mountains. These segments also have. often an unfavorable form for the propulsion and are in their mode of operation not satisfactory. But especially the screwed and tensioned tiibbings have the disadvantage that costly provisions for recesses in the manufacture Cassettes, snug fits, etc. must be taken.
Darüberhinaus wird der Tunnelvortri-eb selbst behindert, indem der Zeitaufwand für Verschraubungen oder Verspannungen die Vortriebsgeschwindigkeit erheblich herabsetzt.In addition, the tunnel drive itself is hindered by the Time spent on screwing or tensioning the advance speed considerably reduces.
Aufgabe der Erfindung ist es, einen nibbing zu entwickeln, der unter Ausnutzung des Pressendruckes der Vortriebsmaschine ohne zusätzliche manuelle Hilfe eingebaut werden kann und dabei in seiner Lage bis zum Schließen des Ringes sicher gehalten wird, ohne daß Verschraubungen oder Verspannungen, das Expandieren des Ringes oder das Eintreiben von Keilsteinen zur Stabilität der Röhre erforderlich sind.The object of the invention is to develop a nibbing that under Utilization of the press pressure of the tunneling machine without additional manual help can be installed and it is safe in its position until the ring is closed is held without screw connections or tension, the expansion of the Ring or the driving in of wedge stones is necessary for the stability of the tube are.
Die Aufgabe wird durch folgende Maßnahmen gelöst: a) An dem zu versetzenden Ttibbing angeordnete Doltlen werden mit der Kraft der Schildvorschubpressen in zugeordnete Büchsen der TLLbbilLgs des bereits versetzten Ringes eingeschoben. Die für den Verbund nötige Haftkraft zwischen Büchsen und Dollen und damit zwischen den einzelnen Tiibbings über die Ringfuge hinweg wird durch elastische und/oder plastische Verformung an den Büchsen und/oder den Dollen erzeugt.The task is solved by the following measures: a) On the one to be relocated Ttibbing arranged Doltlen are assigned with the power of the shield feed presses The sleeves of the TLLbbilLgs of the already offset ring are inserted. The one for the network necessary adhesive force between bushings and oarlocks and so between the individual Tiibbings over the annular joint is by elastic and / or plastic deformation generated on the sleeves and / or the oarlocks.
b) An den Tübbingstirnflächen können zusätzliche (ring. 8) hakenförmige Verriegelungen vorgesehen werden.b) Additional (ring. 8) hook-shaped Interlocks are provided.
Die Kontaktflächen dieser Verriegelungen werden vorzugsweise parallel zu den unter a) beschriebenen Verriegelungen angeordnet, um Zwängungen beim Einbau der Tübbings zu vermeiden. Die Tübbingstirnflächen liegen dabei nicht mit der Tunnelachse in einer Ebene, sondern sind gegen diese so um einen spitzen Winkel gedreht, daß beim Einschieben der Tübbings durch die Vorschubpressen ein Anpreßdruck in der Fuge erzeugt wird. The contact surfaces of these interlocks are preferably parallel to the interlocks described under a) arranged to avoid constraints during installation to avoid the segments. The segment end faces do not lie with the tunnel axis in one plane, but are rotated against this so at an acute angle that when inserting the segments through the feed jacks, a contact pressure in the joint is produced.
Die erfindungsgemäße Lösung ergibt folgende Vorteile. Die Kosten für die nachträgliche Herstellung der Verbindungen zwischen den Tübbings werden eingespart. Die Vortriebsleistung wird gesteigert und der Versetzvorgang wird sicherer. Ein weiterer Vorteil ergibt sich daraus, daß auf die für das Anbringen der bisher üblichen Verbindungselemente nötigen Aussparungen auf der Tunnelinnenfläche verzichtet werden kann, was besonders bei Stollen oder Tunneln mit späterer Wasserführung wichtig ist.The solution according to the invention gives the following advantages. The price for the subsequent production of the connections between the segments is saved. The advance rate is increased and the relocation process is safer. A Another advantage arises from the fact that the previously usual for attaching The necessary recesses on the inner surface of the tunnel are not required for connecting elements can, which is particularly important in tunnels or tunnels with later water flow is.
Ausführungsmöglichkeiten der erfindungsgemäßen Verbindungselemente sind folgende: Büchse und Dollen können aus Stahl (Fig. 1) hergestellt sein. Die Hülse kann dabei kreisförmigen (Fig. 2) oder quadratischen Querschnitt (Fig. 3) haben. Das lichte Maß der Hülse ist geringfügig kleiner gehalten als das Außenmaß des runden Dollens, so daß beim Eintreiben des Dollens die Hülse aufgeweitet wird und dadurch die nötigen Haftkräfte für den Dollen erzeugt werden.Possible embodiments of the connecting elements according to the invention are as follows: The sleeve and oarlocks can be made of steel (Fig. 1). the The sleeve can have a circular (Fig. 2) or square cross-section (Fig. 3) to have. The inside dimension of the sleeve is kept slightly smaller than the external dimension of the round doll, so that the sleeve is expanded when the doll is driven in and thereby the necessary adhesive forces for the oarlock are generated.
Daneben kann die Büchse in Kunststoff (Fig. 4) ausgeführt werden. Zum Einbinden der Büchse in den Beton kann diese anstelle oder neben Ankern eine äußere Profilierung erhalten. Weiterhin kann die Büchse innen und der Dollen außen zur Verbesserung der Haftung eine Profilierung (beispielsweise sägezahnförmig) erhalten.In addition, the sleeve can be made of plastic (Fig. 4). To tie the bushing into the concrete, instead of or in addition to anchors, a external profiling received. Furthermore, the sleeve can be inside and the oarlock outside a profiling (for example sawtooth-shaped) received to improve the adhesion.
Um das Eintreiben des Dollens in die Büchse zu erleichtern und doch gute Hafteigenschaften zu haben, kann die Büchse bei Ausführung in Kunststoff ein Innenprofil mit schwellendem Innendurchmesser (Fig. 5) erhalten, dessen kleinstes lichtes Innenmaß geringer als der Dollenaußendurchmesser ist und dessen Wellentäler so bemessen sind, daß das den Dollen beim Eindringen behindernde Material in sie verdrängt werden kann.To make it easier to drive the bucket into the can and yet The sleeve can have good adhesive properties when it is made of plastic Obtained inner profile with swelling inner diameter (Fig. 5), its smallest inside dimension is smaller than the outside diameter of the oarlock and its wave troughs are dimensioned so that the hindering the oarlocks from entering Material can be displaced into it.
Büchse und Dollen können zu einer konstruktiven Einheit (Fig. 6) zusammengefaßt sein, wobei - verstärkt durch Anordnung von Ankerplatten - eine bessere Verankerung der Verbindungselemente im Tübbing erreicht wird.Bushing and oarlocks can be combined to form a structural unit (Fig. 6) be, whereby - reinforced by the arrangement of anchor plates - a better anchoring the connecting elements in the segment is achieved.
Schließlich kann anstelle des Dollens eine weitere Ankerbüchse angeordnet werden, in die nachträglich vor dem Versetzen des Tübbings ein loser Verriegelungsdollen eingeschoben wird (Fig. 7). Vorteile dieser Lösung sind eine Vereinfachung der Schalung und des Entschalvorganges bei der Herstellung des Tübbings sowie die Möglichkeit, Herstellungstoleran zen der Tübbings und Ungenauigkeiten des Versetzvorganges besser ausgleichen zu können. Letzterem Ziel dient auch eine weitere Ausgestaltung der Erfindung, nach der die Verbindungselemente mit einer die Querbewegung nur unwesentlich behindernden weichen Umschüllung (15) (vorzugsweise aus Gummi) versehen werden.Finally, a further anchor head can be arranged instead of the bucket in which a loose locking oarlock is added before the segment is moved is inserted (Fig. 7). The advantages of this solution are a simplification of the formwork and the demolding process during the production of the tubbing as well as the possibility of Manufacturing tolerances of the segments and inaccuracies in the displacement process are better to be able to compensate. Another embodiment of the Invention, according to which the connecting elements with a transverse movement is only insignificant hindering soft envelope (15) (preferably made of rubber) are provided.
