- Profile strips which are used for such purposes are known from the article 'Joint tapes, joint profiles' published in the journal 'Bauen mit Kunststoffe' (March 1975, pages 128-130). These profile strips are attached to the concrete lining elements by fully and neatly embedding them in the concrete with their side parts. Such a type of attachment is very complex and is only suitable for concrete elements, and only for those that are manufactured on site. Another disadvantage of these profile strips to be embedded in the concrete is that they cannot be exchanged, which would be desirable, since the service life of the profile strips is in many cases likely to be shorter than the service life of the lining elements.
- US-A-4,189,877 describes a profile strip that does not have to be embedded in concrete during its assembly but can be fastened to the lining elements on its side parts by means of screws.
- This profile strip is a composite material and comprises several layers.
- a base layer made of vinyl extends over the entire width of the strip and has a reinforcement strip in the area of the two side parts in order to reinforce those points which are penetrated by fastening elements such as nails or screws with which the profile strip is fastened to the lining elements.
- An insulation layer that is significantly thicker than the base layer extends only over the central part of the profile strip.

- the profile strip is also known as the Omega profile because it has an almost omega-shaped cross section.
- the omega profile is formed by two side parts, which lie in one plane, and by a middle part connecting these side parts, which bulges out of the plane of the side parts and thereby forms a channel for leachate.
- the side parts each have a thickening on their outer edges. With the exception of the thickening along the outer edges of the profile strip, the profile strip has a constant thickness. As a result, the transitions between the side parts and the middle part are strongly rounded.
- retaining strips are arranged on the side parts within the thickening, which are pressed together with the thickenings by means of screws onto the lining elements.
- the lining elements have a reduced wall thickness in their edge areas, as a result of which a type of flat channel is formed on the inside of the tunnel, from which the profile strip protrudes only slightly.
- This arrangement has numerous disadvantages.
- the profile strip consists of two layers, one of which also requires a reinforcing insert, so that it is complex to manufacture and there is a risk that the layers will separate from one another, particularly in the event of displacements.

Description
Die Erfindung betrifft einen Profilstreifen nach dem Oberbegriff des Patentanspruchs 1
bzw. 2 und eine Verwendung des Profilstreifens nach dem Oberbegriff des Patentanspruchs
7.The invention relates to a profile strip according to the preamble of
Es ist üblich, Bahn- und Strassentunnels mit einer Auskleidung aus Eisenbeton zu versehen. Damit diese röhrenförmige Auskleidung etwaigen Bewegungen des Berges nachgeben und die durch Temperaturschwankungen und Bewegungen im Berg verursachten Längenänderungen der Auskleidung ausgleichen kann, wird diese stets in einzelne Abschnitte unterteilt. Die Abschnitte von beispielsweise durchschnittlich 15 cm Länge werden entweder nach üblichen Verfahren an Ort oder auch als Fertigelemente in das vorbereitete Tunnelprofil eingebracht. Zwischen den einzelnen Bau- bzw. Auskleidungselementen wird eine Dilatationsfuge offen gelassen, deren Breite je nach herrschenden Temperaturen bzw. zu erwartenden Temperaturdifferenzen etwa zwischen 1 mm und 15 mm schwanken kann.It is common to provide railway and road tunnels with a reinforced concrete lining. So that this tubular lining gives way to any movements of the mountain and those caused by temperature fluctuations and movements in the mountain Can compensate for changes in length of the lining, it is always divided into individual sections divided. The sections are, for example, an average of 15 cm in length either using the usual methods on site or as ready-made elements in the prepared Tunnel profile introduced. Between the individual building and lining elements a dilatation joint left open, the width of which depends on the prevailing temperatures or expected temperature differences vary between 1 mm and 15 mm can.
Während das Innere des Tunnels im Bereich der Auskleidungselemente vor eindringendem Sickerwasser vollkommen geschützt ist, verbleibt im Bereich der Fugen zwischen den Auskleidungselementen jeweils eine offenen Stelle, an welcher im Berg stets vorhandenes Sickerwasser ungehindert eindringen kann und aus der Fuge senkrecht nach unten tropft.While the inside of the tunnel in the area of the lining elements from penetrating Leachate is completely protected, remains in the area of the joints between the Lining elements each have an open position at which there is always something present in the mountain Seepage water can penetrate unhindered and drips vertically downwards from the joint.
Dies kann zum Beispiel durch Einbringen einer Dichtungsmasse in die Fugen verhindert werden. Diese Art von Abdichtung besitzt jedoch verschiedene Nachteile. So ist es zum Beispiel schwierig oder gar unmöglich, eine Dichtungsmasse zu finden, welche den Änderungen der Fugenbreite infolge der Temperaturschwankungen standhält, ohne zu zerreissen oder sich vom Material der Auskleidungselemente zu lösen. Mit einer solchen Fugenauskleidung ist es auch nicht möglich, einen gegen das Innere des Tunnels abgedichteten Kanal zu erzeugen, welcher dem sich ansammelnden Sickerwasser dazu dienen sollte, längs der Tunnelwand abzufliessen.This can be prevented, for example, by introducing a sealing compound into the joints become. However, this type of seal has several disadvantages. So it is for Example difficult or even impossible to find a sealant that changes withstands the joint width as a result of temperature fluctuations without tearing or detach from the material of the lining elements. With such a joint lining it is also not possible to seal one against the inside of the tunnel To create a channel, which should serve the collecting leachate, to flow along the tunnel wall.
Abhilfe für die genannten Probleme sucht man zu erzielen, indem man die Fuge zwischen zwei Auskleidungselementen mittels eines flexiblen Abdichtbandes in Form eines Profilstreifens überbrückt. Dadurch sucht man sowohl das direkte Eindringen von Sickerwasser ins Tunnelinnere verhindern als auch dem Sickerwasser einen Ablauf in die seitlich des Tunnelbodens verlaufenden Längskanäle ermöglichen. Die zu diesem Zwecke verwendeten vorbekannten Profilstreifen sind aus einem flexiblen Dichtungsmaterial geformt und werden an den dem Tunnelinneren zugewandten Flächen zweier benachbarter Auskleidungselemente befestigt, derart, dass der im Profilstreifen vorgeformte Kanal entlang der gesamten Fuge von einem seitlichen Längskanals zum anderen seitlichen Längskanal im Tunnelboden verläuft. Das Sickerwasser soll somit im Kanal des Profilstreifens an beiden Tunnelflanken ungehindert bis zu den tiefsten Punkten der Fuge ablaufen und dort vollständig von den seitlichen Längskanälen aufgenommen werden.One tries to remedy the above-mentioned problems by dividing the gap between two lining elements by means of a flexible sealing tape in the form of a profile strip bridged. As a result, one looks for both the direct penetration of leachate prevent the inside of the tunnel from seeping into the side of the Enable longitudinal channels running through the tunnel floor. The used for this purpose previously known profile strips are formed from a flexible sealing material and are on the surfaces facing the inside of the tunnel of two adjacent lining elements attached such that the channel preformed in the profile strip along the entire joint from one lateral longitudinal channel to the other lateral longitudinal channel in the Tunnel floor runs. The leachate should therefore be in the channel of the profile strip on both Run the tunnel flanks unimpeded to the lowest points of the joint and there completely are taken up by the side longitudinal channels.
Aus dem in der Zeitschrift 'Bauen mit Kunststoffen' (März 1975, Seiten 128-130) erschienen Artikel 'Fugenbänder, Fugenprofile' sind Profilstreifen bekannt, die zu solchen Zwecken verwendet werden. Diese Profilstreifen werden an den Auskleidungselementen aus Beton befestigt, indem sie mit ihren Seitenteilen voll und satt in den Beton eingebettet werden. Eine solche Art der Befestigung ist sehr aufwendig und eignet sich nur für Betonelemente, und zwar nur für solche, die vor Ort hergestellt werden. Ein weiterer Nachteil dieser in den Beton einzubettenden Profilstreifen ist darin zu sehen, dass sie nicht ausgetauscht werden können, was wünschenswert wäre, da die Lebensdauer der Profilstreifen in vielen Fällen geringer sein dürfte als die Lebensdauer der Auskleidungselmente.Profile strips which are used for such purposes are known from the article 'Joint tapes, joint profiles' published in the journal 'Bauen mit Kunststoffe' (March 1975, pages 128-130). These profile strips are attached to the concrete lining elements by fully and neatly embedding them in the concrete with their side parts. Such a type of attachment is very complex and is only suitable for concrete elements, and only for those that are manufactured on site. Another disadvantage of these profile strips to be embedded in the concrete is that they cannot be exchanged, which would be desirable, since the service life of the profile strips is in many cases likely to be shorter than the service life of the lining elements.
Demgegenüber beschreibt die US-A-4,189,877 einen Profilstreifen, der bei seiner Montage nicht in Beton eingebettet werden muss sondern an seinen Seitenteilen mittels Schrauben an den Auskleidungselementen befestigbar ist. Dieser Profilstreifen ist ein Verbundmaterial und umfasst mehrere Schichten. Eine Grundschicht aus Vinyl erstreckt sich über die ganze Streifenbreite und weist im Bereich der beiden Seitenteile je einen Verstärkungsstreifen auf, um diejenigen Stellen zu verstärken, die von Befestigungselementen wie Nägeln oder Schrauben durchdrungen werden, mit welchen der Profilstreifen an den Auskleidungselementen befestigt wird. Eine Isolationsschicht, die bedeutend dicker ist als die Grundschicht, erstreckt sich nur über den Mittelteil des Profilstreifens. Zwischen der Grundschicht und der Isolationsschicht kann zusätzlich eine verstärkende Einlage, beispielsweise ein textiles oder metallisches Gewebe oder Netz, angeordnet sein. Dieser Profilstreifen weist verschiedene Nachteile auf; so ist er in der Herstellung ausserordentlich aufwendig und im Gebrauch nicht dauerhaft, da die verschiedenen Schichten die Neigung haben, sich voneinander zu lösen.In contrast, US-A-4,189,877 describes a profile strip that does not have to be embedded in concrete during its assembly but can be fastened to the lining elements on its side parts by means of screws. This profile strip is a composite material and comprises several layers. A base layer made of vinyl extends over the entire width of the strip and has a reinforcement strip in the area of the two side parts in order to reinforce those points which are penetrated by fastening elements such as nails or screws with which the profile strip is fastened to the lining elements. An insulation layer that is significantly thicker than the base layer extends only over the central part of the profile strip. A reinforcing insert, for example a textile or metallic fabric or net, can additionally be arranged between the base layer and the insulation layer. This profile strip has several disadvantages; it is extremely complex to manufacture and not durable in use, since the different layers tend to separate.
Ein in der Herstellung einfacherer Profilstreifen ist aus dem in der Zeitschrift 'Baumaschinen und Baugewerbe' (Bd. 26, Nr. 11, November 1979, Seiten 579 - 681) publizierten Artikal 'Untersuchungen zur Druckspannungsrelaxation der Dichtungen der Absenkstrecke des Hamburger Elbtunnels' bekannt. Dieser Profilstreifen ist zweischichtig und besteht aus Elastomeren, nämlich auf der dem Tunnelinneren zugewandten Seite aus CR-Vulkanisat und auf der der Fuge und den Auskleidungselementen zugewandten Seite aus NR-Vulkanisat mit einer verstärkenden Polyamid-Gewebeeinlage. Der Profilstreifen ist auch unter der Bezeichnung Omega-Profil bekannt, da er einen annähernd omega-förmigen Querschnitt ausweist. Das Omega-Profil wird gebildet durch zwei Seitenteile, die in einer Ebene liegen, und durch einen diese Seitenteile verbindenden Mittelteil, der sich aus der Ebene der Seitenteile herauswölbt und dadurch einen Kanal für Sickerwasser bildet. Die Seitenteile weisen an ihren äusseren Rändern je eine Verdickung auf. Mit Ausnahme der Verdickungen längs der äusseren Ränder des Profilstreifens weist der Profilstreifen eine konstante Dicke auf. Dies hat zur Folge, dass die Übergänge zwischen den Seitenteilen und dem Mittelteil stark gerundet sind. Um dennoch eine dichtende Auflage der Seitenteile an den Auskleidungselementen zu erhalten, werden innerhalb der Verdikkung Halteleisten auf den Seitenteilen angeordnet, welche zusammen mit den Verdickungen mittels Schrauben auf die Auskleidungselemente gepresst werden. Die Auskleidungselemente weisen in ihren Randbereichen eine verminderte Wandstärke auf, wodurch an der Tunnelinnenseite eine Art flacher Rinne gebildet wird, aus welcher der Profilstreifen nur wenig herausragt. Diese Anordnung weist zahlreiche Nachteile auf. Erstens besteht der Profilstreifen aus zwei Schichten, von denen eine ausserdem einer verstärkenden Einlage bedarf, so dass er in der Herstellung aufwendig ist und die Gefahr besteht, dass sich, insbesondere bei Verschiebungen, die Schichten voneinander lösen. Zweitens ist die Herstellung der Auskleidungselemente wegen der in der Wandstärke verminderten Randbereiche erschwert. Drittens ist ein dichtes Anliegen der Seitenteile an den Auskleidungselementen nur mit Hilfe der Montageleisten möglich, die nicht nur beschafft werden müssen sondern auch den Montagevorgang erschweren. Viertens besteht bei einer Verkleinerung der Fuge bzw. einem dadurch bedingten Zusammenrücken der Seitenteile die Gefahr, dass die Halteleisten mit ihren dem Mittelteil zugewandten Kanten das elastomere Material des Profilstreifens beschädigen.A profile strip which is simpler to produce is known from the article 'Investigations into the Compression Stress Relaxation of the Seals of the Lowering Section of the Hamburg Elbe Tunnel' published in the journal 'Baumaschinen und Baugewerbe' (Vol. 26, No. 11, November 1979, pages 579 - 681). This profile strip has two layers and consists of elastomers, namely CR vulcanizate on the inside of the tunnel and NR vulcanizate on the side facing the joint and the lining elements with a reinforcing polyamide fabric insert. The profile strip is also known as the Omega profile because it has an almost omega-shaped cross section. The omega profile is formed by two side parts, which lie in one plane, and by a middle part connecting these side parts, which bulges out of the plane of the side parts and thereby forms a channel for leachate. The side parts each have a thickening on their outer edges. With the exception of the thickening along the outer edges of the profile strip, the profile strip has a constant thickness. As a result, the transitions between the side parts and the middle part are strongly rounded. In order nevertheless to obtain a sealing support of the side parts on the lining elements, retaining strips are arranged on the side parts within the thickening, which are pressed together with the thickenings by means of screws onto the lining elements. The lining elements have a reduced wall thickness in their edge areas, as a result of which a type of flat channel is formed on the inside of the tunnel, from which the profile strip protrudes only slightly. This arrangement has numerous disadvantages. First, the profile strip consists of two layers, one of which also requires a reinforcing insert, so that it is complex to manufacture and there is a risk that the layers will separate from one another, particularly in the event of displacements. Secondly, the production of the lining elements is difficult because of the reduced edge areas in the wall thickness. Thirdly, a tight fit of the side parts against the lining elements is only possible with the help of the assembly strips, which not only have to be procured but also complicate the assembly process. Fourthly, when the joint is reduced or the side parts are moved closer together as a result, there is a risk that the holding strips, with their edges facing the central part, will damage the elastomeric material of the profile strip.
Es ist deshalb Aufgabe der Erfindung, einen solchen Profilstreifen in der Art des eben beschriebenen Omega-Profils so zu verbessern, dass er die genannten Nachteile der mehrschichtigen Profilteile nicht aufweist.It is therefore an object of the invention to provide such a profile strip in the manner described above Improve omega profile so that it has the disadvantages of multilayered Does not have profile parts.
Diese Aufgabe wird erfindungsgemäss durch die Merkmale des kennzeichnenden Teils
des Patentanspruchs 1 gelöst. According to the invention, this object is achieved by the features of the characterizing part of
Vorteilhafte Weiterbildungen der erfindungsgemässen Profilstreifen sind durch die Patentansprüche 2 bis 5 definiert.Advantageous developments of the profile strips according to the invention are defined by claims 2 to 5 .
Die Aufgabe der Erfindung betrifft ferner die Verwendung des neuen Profilstreifens. Diese dritte Aufgabe besteht darin, Massnahmen vorzuschlagen, welche eine Befestigung der Profilstreifen erlauben, die einfacher ist als die herkömmliche Befestigung mit Schrauben.The object of the invention also relates to the use of the new profile strip. This third task is to propose measures to secure the Allow profile strips that are easier than conventional fastening with screws.
Diese Aufgabe wird durch die Merkmale des kennzeichnenden Teils des Patentanspruchs
6 gelöst.This object is achieved by the features of the characterizing part of
Es wird somit ein erster Profilstreifen vorgeschlagen, der aus einem Abdichtungsmaterial von genügender Flexibilität hergestellt ist, das ohne Belastung formbeständig ist, das unter den im Tunnelbau herrschenden Verhältnissen seine Undurchlässigkeit gegen Wasser über längere Zeiträume bewahrt und eine bei etwaigen Verschiebungen genügende Festigkeit aufweist. Geeignet ist Gummi in einer gegen Oyxdation und Alterung geschützten Qualität. Weiter kommen wasserbeständige flexible Kunststoffe wie zum Beispiel weichmacherhaltiges Polyvinylchlorid, in Frage.A first profile strip is thus proposed, which is made of a sealing material is made of sufficient flexibility that is dimensionally stable without stress, the under the conditions prevailing in tunnel construction, its impermeability to water Preserved over longer periods of time and sufficient strength for any shifts having. Rubber is suitable in a protected against oxidation and aging Quality. There are also water-resistant flexible plastics such as those containing plasticizers Polyvinyl chloride, in question.
Es ist ferner eine zweiter Profilstreifen vorgesehen mit im wesentlichen gleichbleibender Wandstärke, der aber in den Übergangsbereichen zwischen den Seitenteilen und dem Mittelteile auf der den Bauelementen abgewandten Seite je eine Verringerung der Wandstärke aufweist, die sich in Längsrichtung des Profilstreifens erstreckt, und die beispielsweise hohlkehlenartig ausgebildet sein kann. Diese Ausnehmung ermöglicht, dass bei den Übergängen vom Mittelteil zu den Seitenteilen keine grossen Abrundungen notwendig sind, sondern dass, beispielsweise bei einem U-förmigen oder rechteckigen Kanalquerschnitt, ein Winkel von 90° zwischen dem vertikalen Kanalwandungsteil und dem Seitenteil eingehalten werden kann, so dass sich die Seitenteile über ihre gesamte Breite problemlos und ohne die Verwendung zusätzlicher Hilfselemente an die Bauelemente anlegen und befestigen lassen. Die hohlkehlenartige Ausnehmung vermindert aus-serdem den Biegewiderstand des Profilstreifens gegen die Beanspruchung, die beim Zusammenrücken der beiden vom Profilstreifen verbundenen Bauelemente auf den Profilstreifen ausgeübt werden. A second profile strip is also provided with a substantially constant one Wall thickness, but in the transition areas between the side parts and the Middle parts on the side facing away from the components each have a reduction in wall thickness has, which extends in the longitudinal direction of the profile strip, and for example can be formed like a groove. This recess enables the Transitions from the middle section to the side sections do not require any large roundings but that, for example in the case of a U-shaped or rectangular channel cross section, an angle of 90 ° between the vertical duct wall part and the side part can be adhered to, so that the side parts over their entire width easily and without using additional auxiliary elements on the components and fasten. The groove-like recess also reduces the bending resistance of the profile strip against the stress that occurs when the two components connected by the profile strip are exerted on the profile strip.
Der Kanal, der durch den neuen Profilstreifen gebildet wird, kann im Querschnitt U-förmig sein.The channel that is formed by the new profile strip can be U-shaped in cross section be.
Andere Kanäle können einen polygonalen, insbesondere einen rechteckigen Querschnitt aufweisen.Other channels can have a polygonal, in particular a rectangular cross-section exhibit.
Die vorbekannten Profilstreifen werden, wie weiter oben erwähnt, entweder in den Beton, aus dem die Bauelemente bestehen, eingebettet oder mittels geeigneter Befestigungselemente wie beispielsweise Schrauben an den Bauelementen befestigt. Eine wesentliche Vereinfachung der Montage und gleichzeitig eine Verbesserung der Abdichtung erhält man bei den neuen Profilstreifen dadurch, dass sie zur Verklebung an den Bauelementen geeignet sind. Die für die Klebeverbindung vorgesehenen Flächen der Seitenteile werden vorzugsweise mit einer Aufrauhung, beispielsweise feinen Rippen, versehen, die ein besseres Haften bewirken. Als Klebemittel verwendet man mit Vorteil Kontaktkleber. Diese bestehen aus einer Lösung von natürlichem oder synthetischem Gummi in einem leichtflüchtigen, organischen Lösungsmittel. Der Kontaktkleber wird auf die beiden zur gegenseitigen Anlage bestimmten Flächen gestrichen ; nach dem Verdunsten des Lösungsmittels werden die beiden Flächen aneinander gelegt und dadurch die entsprechenden Teile miteinander verbunden.The previously known profile strips are, as mentioned above, either in the concrete, from which the components consist, embedded or by means of suitable fastening elements such as screws attached to the components. An essential one Simplify assembly while improving sealing with the new profile strips in that they are used for gluing to the components are suitable. The areas of the side parts intended for the adhesive connection are preferably with a roughening, for example fine ribs, which provide a better Adhere. Contact adhesive is advantageously used as the adhesive. This consist of a solution of natural or synthetic rubber in a volatile, organic solvents. The contact adhesive becomes mutual on the two Plant deleted certain areas; after the solvent has evaporated the two surfaces are placed next to each other and thereby the corresponding parts connected with each other.
Obwohl im allgemeinen homogene Profilstreifen alle erforderlichen Eigenschaften aufweisen, können für höchste Ansprüche auch Profilstreifen mit verstärkenden Fasern oder Gewebeeinlagen verwendet werden.Although generally homogeneous profile strips have all the necessary properties, can also use profile strips with reinforcing fibers or Fabric inlays are used.
Die Seitenteile und das röhrenförmige Mittelteil des flexiblen Profilstreifens bestehen aus einem Stück und sind daher nahtlos miteinander verbunden. Wie aus den Figuren 1 bis 6 ersichtlich, ist der im wesentlichen rechtwinklige Uebergang (4) zwischen Seiten- und Mittelteil in seiner Dicke etwas vermindert und erleichtert dadurch die beim Verengen und Erweitern der Fuge resultierende Veränderung des Winkels zwischen Mittel- und Seitenteilen. The side parts and the tubular middle part of the flexible profile strips consist of one piece and are therefore seamlessly connected. As from Figures 1 6 to 6 is the substantially rectangular one Transition (4) between the side and middle part in its thickness somewhat diminishes and thereby facilitates the narrowing and widening the joint resulting in change in angle between middle and side parts.
Das Wesen der Erfindung und ihre Anwendung ist aus den Figuren No. 1 bis 6 ersichtlich, wobei jedoch die möglichen Ausführungsformen durch die Figuren in keiner Weise eingeschränkt sein sollen.The essence of the invention and its application is from the figures No. 1 to 6 can be seen, but the possible embodiments by the figures in any way should be restricted.
Figur 1 zeigt ein Stück eines erfindungsgemässen Profils in perspektivischer Ansicht mit den beiden Seitenteilen (1) und dem zylindrisch geformten Mittelteil (3), welcher im fertig verlegten Profil als Ablaufkanal für das Sickerwasser dient. Mit (2) sind die Rippen angedeutet, die ein besseres Haften der Verklebung mit der Betonauskleidung bewirkt. Figure 1 shows a piece of a profile according to the invention in a perspective view with the two side parts (1) and the cylindrically shaped middle part (3), which serves as a drainage channel for the leachate in the finished laid profile. With (2) the ribs are indicated, which causes a better adhesion of the bond with the concrete lining.
Figur 2 zeigt einen Schnitt durch das gleiche Profil wie in Figur 1, wobei für die einzelnen Teile die gleichen Bezugsnummern verwendet werden. FIG. 2 shows a section through the same profile as in FIG. 1, the same reference numbers being used for the individual parts.
Figur 3 zeigt den selben Schnitt wie Figur 2, jedoch in einem Zustand wie er sich einstellt, wenn die Fuge durch Ausdehnung der Verkleidungselemente enger geworden ist, wie dies durch die beiden Pfeile angedeutet ist. Figure 3 shows the same section as Figure 2, but in a state as it arises when the joint has become narrower due to expansion of the cladding elements, as indicated by the two arrows.
Figur 4 zeigt einen Schnitt durch ein Profil, bei welchem der Mittelkanal (5) rechteckig geformt ist. Figure 4 shows a section through a profile in which the central channel (5) is rectangular.
Figur 5 zeigt einen Schitt durch ein fertig verlegtes Profil (6), welches zwei benachbarte Wandelemente (7) aus Beton miteinander verbindet. Figure 5 shows a step through a completely installed profile (6) which connects two adjacent wall elements (7) made of concrete.
Figur 6 zeigt den Blick ins Innere eines Tunnels mit einem flexiblen Profilstreifen (8), welcher die beiden benachbarten Auskleidungselemente (9) und (10) miteinander verbindet. Es ist deutlich sichtbar, wie der Mittelkanal des Profils an seinem untern Ende in die beiden seitlichen Ablaufkanäle (11) mündet. FIG. 6 shows the view inside a tunnel with a flexible profile strip (8) which connects the two adjacent lining elements (9) and (10) to one another. It is clearly visible how the central channel of the profile opens into the two lateral outlet channels (11) at its lower end.
