Description

Die Erfindung betrifft eine Straßentunnelanordnung nach dem Oberbegriff des Anspruchs 1, ein Verfahren zur Herstellung einer derartigen Straßentunnelanordnung und ein Straßentunnelnetzwerk unter Verwendung einer derartigen Straßentunnelanordnung.The invention relates to a road tunnel arrangement according to the preamble of claim 1, a method for producing such a road tunnel arrangement and a Road tunnel network using such a road tunnel arrangement.

Es wird geschätzt, dass der Verkehr in Europa und insbesondere in den Schwellen- und Entwicklungsländern noch auf eine Dauer von circa 30 Jahren stark zunehmen wird. Das größte Verkehrswachstum werden hier die sogenannten Megastädte, also Metropolen und Ballungsräume mit vielen Millionen Einwohnern zu verzeichnen haben. Unabhängig von den öffentlichen Verkehrsmitteln, insbesondere dem öffentlichen Personennahverkehr in solchen Städten, werden die vorhandenen Innenstadtstraßen dem zunehmenden Verkehrsaufkommen nicht mehr gewachsen sein. Auch eine weitgehende Auslagerung auf den öffentlichen Personennahverkehr ist nicht möglich, und zwar nicht nur wegen fehlender Akzeptanz, sondern auch, weil der öffentliche Personennahverkehr nicht die Kapazität hat, einen großen Teil des Individualverkehrs zusätzlich aufzunehmen.It is estimated that transport in Europe and especially in the emerging and Developing countries will continue to grow strongly over a period of about 30 years. The The biggest traffic growth here are the so-called megacities, ie metropolises and cities Agglomerations with many millions of inhabitants. Regardless of the public transport, especially public transport in such areas Cities, the existing inner-city streets will be the increasing traffic can no longer cope. Also, a substantial outsourcing to the public Passenger transport is not possible, and not only because of lack of acceptance, but also because the local public transport does not have the capacity, a big one Part of the individual traffic addition.

Die JP 10246005 beschreibt ein Konzept zur Energieversorgung eines Ballungsraums unter Verwendung von Tunneln und Tunnelröhren, wobei nur am Rande daraufhingewiesen wird, dass der Verkehr in Tunneln geführt werden kann. Die FR 2681088 hat eine Straßentunnelanordnung zur Verkehrserschließung von Ballungsräumen zum Gegenstand, wobei auch eine Ringstraße vorgesehen ist sowie eine Vielzahl von innerhalb dieser Ringstraße in regelmäßigen Abständen angeordneten und straßenverkehrsmäßig an die Ringstraße angebundenen, in einer Tiefe unterhalb der Ver- und Entsorgungssysteme des Ballungsraumes verlaufenden Straßentunnelröhren sowie unterirdischer Parkgaragen mit Zugangsvorrichtungen für Personen und Güter zur Oberfläche des Ballungsraumes.JP 10246005 describes a concept for supplying energy to a metropolitan area Use of tunnels and tunnels, with only marginal attention that the traffic can be carried in tunnels. The FR 2681088 has a Road tunnel arrangement for the traffic development of agglomerations, wherein a ring road is provided and a plurality of within this Ring road arranged at regular intervals and road traffic to the Ring road, at a depth below the supply and disposal systems of the Conurbation extending road tunnel tubes and underground parking garages with Access devices for persons and goods to the surface of the conurbation.

Schließlich offenbart die EP 0 999 307 A2 desselben Anmelders eine Straßentunnelanordnung zur Verkehrserschließung von Ballungsräumen mit allen Merkmalen des Oberbegriffs des Anspruchs 1, wobei insbesondere auf das Ausführungsbeispiel gemäß Figur 4 der genannten Druckschrift verwiesen wird, welches ein schachbrettartiges Muster sich unter einem Winkel von 90° kreuzender Straßentunnelröhren zeigt, wobei jede Tunnelröhre zur Aufnahme einer Einbahnstraße ausgebildet ist und jeweils benachbarte Tunnelröhren gegenläufigen Verkehr führen.Finally, EP 0 999 307 A2 of the same Applicant discloses a road tunnel arrangement for the development of urban areas with all the characteristics of the generic term of the Claim 1, wherein in particular the embodiment according to FIG 4 of the above Reference is made, which is a checkered pattern at an angle of 90 ° crossing road tunnel tubes, each tunnel tube for receiving a One-way street is formed and each adjacent tunnel tubes counter-rotating traffic to lead.

Die in der EP 0 999 307 A2 beschriebene Straßentunnelanordnung bedeutet zwar einen erheblichen Fortschritt gegenüber den bekannten Anordnungen, ist jedoch in der Ausführung kompliziert und damit kostenintensiv, weil die sich kreuzenden Straßentunnelröhren in verschiedenen Tiefen angeordnet sind, um eine kreuzungsfreie Anordnung zu erzielen. An jedem Kreuzungspunkt zweier Tunnelröhren muss mit Seitenabbiegern und sogenannten Schnecken (vergleiche Figur 2 aus der EP 0 999 307 A2) gearbeitet werden, wobei diese Seitenabbieger und Schnecken auch den Höhenunterschied der sich kreuzenden Straßentunnelröhren überbrücken müssen.Although the road tunnel arrangement described in EP 0 999 307 A2 means a considerable progress over the known arrangements, but is in the execution complicated and thus costly because the intersecting street tunnel tubes in different depths are arranged to achieve a crossing-free arrangement. At Each crossing point of two tunnel tubes must be equipped with side benders and so-called Screws (see Figure 2 from EP 0 999 307 A2) are worked, these Seitenabbieger and snails and the height difference of the intersecting Road tunnel tubes have to bridge.

Es besteht daher die Aufgabe, eine gattungsgemäße Straßentunnelanordnung so weiterzubilden, dass sie in der Herstellung einfacher und kostengünstiger ist und dennoch einen reibungslosen Verkehrsfluss gewährleistet.There is therefore the task of a generic road tunnel arrangement so educate that it is easier and cheaper to manufacture and yet ensures a smooth flow of traffic.

Gelöst wird diese Aufgabe mit den kennzeichnenden Merkmalen des Anspruchs 1. Vorteilhafte Ausgestaltungen sind den Unteransprüchen entnehmbar.This problem is solved by the characterizing features of claim 1. Advantageous embodiments are the dependent claims.

Der Kerngedanke der Erfindung besteht darin, die sich kreuzenden Straßentunnelröhren alle in derselben Tiefe unter dem Erdboden zu bauen und jeweils zwei parallele Straßentunnelröhren zu einem Paar für gegenläufigen Verkehr zu verbinden, wobei jede Straßentunnelröhre eine Einbahnstrasse mit mehreren Fahrstreifen aufnimmt. Dort wo sich zwei Paare von Tunnelröhren kreuzen, ist eine großräumige Kreisverkehranordnung vorgesehen, in welche vier Tunnelröhren mit zufließendem Verkehr einmünden und von der vier Tunnelröhren Verkehr abführen. Die hierbei auftretenden Abstützungsprobleme aufgrund der extrem großräumigen Untertunnelung im Bereich der Kreisverkehranordnungen werden dadurch gelöst, dass im Zentrum jeder Kreisverkehranordnung ein Quader unangetastet bleibt und damit das natürlich gewachsene und stabile Erdreich als zentrale Abstützung für den großräumig untertunnelten Bereich der Kreisverkehranordnung wirkt.The essence of the invention is that the intersecting road tunnel tubes all to build at the same depth below the ground and two parallel ones Street tunnels to connect to a pair for opposing traffic, each one Road Tunnel tube a one-way street with several lanes takes up. There where Two pairs of tunnel tubes intersect is a large-scale roundabout arrangement provided, in which four tunnels with inflowing traffic and open from the four tunnels discharge traffic. The case occurring support problems due the extremely large-scale Untertunnelung in the area of the roundabout arrangements become solved in that in the center of each roundabout arrangement a cuboid remains untouched and thus the naturally grown and stable soil as a central support for the large-scale sub-tunneled area of the roundabout arrangement acts.

Die Anordnung ist so konzipiert, dass sie aus der Sicht der bautechnischen Abwicklung eine wirtschaftlich optimale Lösung darstellt. Alle vier Straßentunnelröhren können nämlich mit geradeaus führenden Tunnelbohrmaschinen hergestellt werden, welche standardmäßig im Tunnelbau verwendet werden und dem Fachmann bekannt sind. Die im Bereich der Kreuzungen benötigten Sonderflächen zur Erstellung der Kreisverkehranordnungen werden durch Spezialgeräte hergestellt, dennoch können die Tunnelbohrmaschinen auch am Ort des späteren Kreisverkehrs geradeaus durchfahren, ohne dass es notwendig wäre, am Ort des Kreisverkehrs besondere Bauverfahren anzuwenden. Es werden also zunächst einfach gerade führende Tunnelröhren hergestellt und an den sich automatisch ergebenden Kreuzungen wird anschließend durch Spezialgeräte weiteres Erdreich abgetragen, um die Grundfläche für die Kreisverkehranordnungen bereitzustellen.The arrangement is designed in such a way that from the point of view of the structural development a represents economically optimal solution. All four road tunnel tubes can namely with Straight ahead tunnel boring machines are manufactured, which are standard in Tunneling are used and are known in the art. The in the field of Intersections needed to be special areas for the creation of the roundabout arrangements made by special equipment, however, the tunnel boring machines can also at the place of go through the roundabout straight ahead, without it being necessary at the place of the Roundabout apply special construction procedures. So at first it just becomes straight leading tunnel tubes are produced and at the automatically resulting intersections then removed by special equipment further soil to the base for the To provide roundabout arrangements.

Zwei Ausführungsbeispiele der Erfindung werden im folgenden unter Bezugnahme auf jeweils eine begleitende Zeichnung näher erläutert. Hierbei zeigen:

Figur 1:
Eine Planansicht einer ersten Ausführungsform einer erfindungsgemäßen Straßentunnelanordnung; und
Figur 2:
eine Planansicht einer zweiten Ausführungsform einer erfindungsgemäßen Straßentunnelanordnung.
Two embodiments of the invention will be explained in more detail below with reference to an accompanying drawing. Hereby show:
FIG. 1:
A plan view of a first embodiment of a road tunnel arrangement according to the invention; and
FIG. 2:
a plan view of a second embodiment of a road tunnel arrangement according to the invention.

Bei beiden Ausführungsformen der erfindungsgemäßen Straßentunnelanordnung kreuzen sich im Untergrund, beispielsweise unterhalb eines Ballungsraumes, zwei Paare 1 und 2 von Tunnelröhren 1', 1", 2', 2". Das erste Paar 1 besteht aus den beiden einzelnen Tunnelröhren 1' und 1", welche parallel zueinander in einem Abstand von etwa 30 m zueinander verlaufen. Das zweite Paar 2 besteht aus den beiden Tunnelröhren 2' und 2", welche ebenfalls parallel zueinander und ebenfalls in einem Abstand von 30 m zueinander verlaufen. Die Tunnelröhren 1' und 1" des ersten Paars 1 verlaufen senkrecht zu den Tunnelröhren 2' und 2" des zweiten Paars 2, und zwar in der gleichen Tiefe unter der Erdoberfläche, so dass die in den Figuren 1 bzw. 2 dargestellte Kreuzungsanordnung entsteht.In both embodiments of the road tunnel arrangement according to the invention intersect in the underground, for example below a metropolitan area, two pairs 1 and 2 of Tunnel tubes 1 ', 1 ", 2', 2". The first pair 1 consists of the two individual tunnel tubes 1 ' and 1 ", which are parallel to each other at a distance of about 30 m from each other. The second pair 2 consists of the two tunnel tubes 2 'and 2 ", which are also parallel to each other and also at a distance of 30 m from each other. The tunnel tubes 1 'and 1 "of the first pair 1 are perpendicular to the tunnel tubes 2' and 2" of the second Pair 2, and that at the same depth below the earth's surface, so that in the figures 1 or 2 illustrated crossing arrangement arises.

Jede Tunnelröhre 1', 1", 2', 2" beinhaltet eine Einbahnstraße mit mehreren, in den dargestellten Ausführungsbeispielen drei, Fahrstreifen. Jede Tunnelröhre ist in an sich bekannter Weise hergestellt, nämlich z.B. mit einer geradeaus führenden Tunnelbohrmaschine, insbesondere einer Schildvortriebsmaschine, also mit Techniken, wie sie aus dem Tunnel- und Bergbau bekannt sind. Ferner ist jede Tunnelröhre innenseitig ausgekleidet und armiert, worauf im folgenden jedoch nicht näher eingegangen wird, da diese Maßnahmen ebenfalls aus dem Berg- und Tunnelbau bekannt sind. Each tunnel tube 1 ', 1 ", 2', 2" includes a one-way street with several, in the illustrated embodiments three, lanes. Each tunnel tube is in itself known manner, namely e.g. with a straight ahead Tunnel boring machine, in particular a shield tunneling machine, ie with techniques such as they are known from the tunnel and mining industry. Furthermore, each tunnel tube is inside lined and armored, which will not be discussed in more detail below, as these Measures are also known from mining and tunneling.

Die Tunnelröhren 1', 1", 2', 2" befinden sich vorzugsweise in einer Tiefe von etwa 30 - 50 m unter der Erdoberfläche, beispielsweise unterhalb eines Ballungsraums.The tunnel tubes 1 ', 1 ", 2', 2" are preferably at a depth of about 30 - 50 m below the earth's surface, for example below a conurbation.

Die beiden sich kreuzenden Paare 1 und 2 von Tunnelröhren umschließen in der Draufsicht (= Planansicht) ein Rechteck 4, welches in beiden Ausführungsbeispielen aufgrund des gleichen Abstandes der Tunnelröhren 1' und 1" des ersten Paars 1 und der Tunnelröhren 2' und 2" des zweiten Paars 2 ein Quadrat ist. Innerhalb dieses Quadrats bleibt das natürliche Erdreich völlig unangetastet, da die geradeaus geführten Tunnelanordnungen 1', 1", 2', 2" jeweils an diesem Rechteck vorbeiführen bzw. es begrenzen. Im Dreidimensionalen entspricht das Quadrat 4 einem Quader, welcher aus natürlichem, verfestigten Erdreich besteht und die Decke der gesamten, im folgenden näher beschriebenen Kreuzungsanordnung, abstützt.The two intersecting pairs 1 and 2 of tunnel tubes enclose in plan view (= Plan view) a rectangle 4, which in both embodiments due to the equal distance of the tunnel tubes 1 'and 1 "of the first pair 1 and the tunnel tubes 2' and 2 "of the second pair 2 is a square. Within this square, the natural remains Soil completely untouched, since the straight-ahead tunnel arrangements 1 ', 1 ", 2', 2" each past this rectangle or limit it. In the three-dimensional corresponds the square 4 a cuboid, which consists of natural, solidified soil and the Ceiling of the entire, described in more detail below crossing arrangement supported.

Gegenüber jeder der vier Außenseiten 5 des Rechtecks 4 im Zentrum des Kreuzungsbereiches ist das Erdreich in den schraffiert dargestellten Bereichen 6 abgetragen. Jeder Bereich 6 wird einerseits begrenzt durch den - bezogen auf das Zentrum der Anordnung - Außenrand des Verlaufs einer Tunnelröhre (z.B. 2") und den Innenrand des Verlaufs der beiden hierzu senkrecht verlaufenden Tunnelröhren des anderen Paars (z.B. 1', 1 "), wobei sich die Beispiele auf den in den Figuren 1 und 2 rechts dargestellten gestrichelten Bereich 6 bezogen. Diese gestrichelten Bereiche 6 werden nach Fertigstellung der Tunnelröhren 1', 1", 2', 2" durch Spezialräumgeräte hergestellt. Aus den Zeichnungen ist ersichtlich, dass das zusätzlich freizuräumende Volumen für die Bereiche 6 gering ist im Vergleich zu dem ohnehin vorhandenen, bereits durch die Schildvortriebsmaschinen bei der Erzeugung der Tunnelröhren 1', 1", 2', 2" erzeugte Volumen.Opposite each of the four outer sides 5 of the rectangle 4 in the center of the crossing area the soil is removed in the hatched areas 6 shown. Each area will be 6 limited on the one hand by the - with respect to the center of the arrangement - the outer edge of the A tunnel tube (e.g., 2 ") and the inner edge of the course of the two vertically extending tunnel tubes of the other pair (e.g., 1 ', 1 "), with examples refer to the dashed area 6 shown on the right in Figures 1 and 2. These Dashed areas 6 are after completion of the tunnel tubes 1 ', 1 ", 2', 2" by Special cleaners manufactured. From the drawings it can be seen that the additional clearance volume for areas 6 is low compared to that anyway existing, already by the shield tunneling machines in the production of the tunnel tubes 1 ', 1 ", 2', 2" generated volume.

Zur Fertigstellung des Bauwerks können die Außenseiten 5 des zentralen Rechtecks bei besonderen geologischen Bedingungen, und zwar insbesondere, wenn das Rechteck aus losem Erdreich besteht, bautechnisch verstärkt, z.B. betoniert werden. In gleicher Weise kann der gesamte Decken- und Wandbereich der Anordnung bautechnisch verstärkt werden.To complete the building, the outer sides 5 of the central rectangle at particular geological conditions, especially if the rectangle is loose Soil exists, reinforced structurally, e.g. be concreted. In the same way, the entire ceiling and wall area of the arrangement are reinforced structurally.

Die in den Figuren horizontal bzw. vertikal dünn gestrichelten, kreissegmentförmigen Bereiche unmittelbar an den Außenseiten 5 des Quadrats 4 sowie der außerhalb dieser Bereiche schraffierte ringförmige Bereich sind zwar untertunnelt und freigeräumt, da sie ja die Verlängerungen der Straßentunnelröhren sind, werden aber für den Kreisverkehr nicht genutzt. Diese Flächen können entweder frei gelassen und asphaltiert werden, oder es können Gebäude oder andere Einrichtungen, z.B. Polizei, Rettungsdienste, Feuerwehr, Bereitschaftsdienste, Überwachungsdienste etc. darauf angeordnet werden.The dashed horizontally or vertically thin in the figures, circular segment-shaped Areas directly on the outer sides 5 of the square 4 and the outside of this Areas shaded annular area are indeed undermined and cleared, since they are yes The extensions of the road tunnel tubes are, but are not for the roundabout used. These areas can either be left free and paved, or they can Buildings or other facilities, e.g. Police, Rescue Services, Fire Brigade, Standby services, surveillance services, etc.

Vorzugsweise weist jede Einbahnstraße 3 innerhalb jeder Tunnelröhre 1', 1", 2', 2" drei Fahrstreifen auf, wobei diese jedoch auch zwei, vier oder mehr Fahrstreifen aufweisen kann. Die gleiche Anzahl von Fahrstreifen weist vorzugsweise jeder Kreisverkehr auf, so dass ein reibungsloser Übergang von den Einbahnstraßen in den Kreisverkehr und wieder aus diesem heraus möglich ist.Preferably, each one-way street 3 within each tunnel tube 1 ', 1 ", 2', 2" has three Lanes, but this may also have two, four or more lanes. The same number of lanes preferably has each roundabout, so that a smooth transition from the one-way streets to the roundabout and back out of this out is possible.

Es ist ferner vorteilhaft, im Bereich der Einmündung jeder Tunnelröhre 1' bzw. 2", welche der Kreisverkehranordnung Verkehr zuführt, zwischen dieser Tunnelröhre 1' bzw. 2" und der Kreisverkehranordnung Erdreich abzutragen. Hierbei wird der in den Figuren dargestellte Durchblick 7 zwischen der Tunnelröhre 1' bzw. 2' und der Kreisverkehranordnung erzeugt und die sich dem Kreisverkehr nähernden Fahrzeuge sehen besser die aus dem Kreisverkehr kommenden Fahrzeuge. Dieser Durchblick 7 kann in der Draufsicht (Planansicht) etwa die Form eines Dreiecks aufweisen oder auch anderweitig gestaltet sein.It is also advantageous, in the region of the junction of each tunnel tube 1 'or 2 ", which of the Traffic circle feeds traffic between this tunnel tube 1 'and 2 "and the Roundabout arrangement soil to remove. Here, the illustrated in the figures View 7 generated between the tunnel tube 1 'and 2' and the roundabout arrangement and the vehicles approaching the roundabout see better off the roundabout coming vehicles. This view 7 can in plan view (plan view) as the Have a shape of a triangle or otherwise designed.

Ferner ist es vorteilhaft, dass das bei den äußeren Eckpunkten A sich kreuzender Tunnelröhren 1', 1", 2', 2" verbleibende Erdreich in der Draufsicht (Planansicht) unter Bildung einer Schräge oder konvexen Abrundung abgetragen ist, um erstens eine bessere Überblickbarkeit zu gewährleisten und zweitens die Unfallfolgen bei Unfällen in diesem Bereich abzumildern.Further, it is advantageous that at the outer corners A intersecting Tunnel tubes 1 ', 1 ", 2', 2" remaining soil in plan view (plan view) below Formation of a sloping or convex rounding is removed, first, a better Survivability and secondly the accident consequences of accidents in this Mitigate area.

Während die bisherigen Ausführungen auf beide Ausführungsbeispiele zutrafen, unterscheidet sich das zweite Ausführungsbeispiel gemäß Figur 2 vom ersten Ausführungsbeispiel gemäß Figur 1 dadurch, dass bei den äußeren Eckpunkten A sich kreuzender Tunnelröhren 1', 1 ", 2', 2" soviel Erdreich abgetragen ist, dass ein Abbiegefahrstreifen 9 entsteht, über welchen die Fahrzeuge von der zubringenden Tunnelröhre, z.B. 1', in die abführende Tunnelröhre, z.B. 2", abbiegen können ohne in den Kreisverkehr selbst einzufahren. Diese Anordnung dient der Vermeidung von Unfällen. Es sind hier verkehrstechnische Maßnahmen vorzusehen, die eine frühzeitige Anordnung des abbiegenden Verkehrs in die rechte Spur vorschreiben.While the previous versions were true for both embodiments, a distinction the second embodiment according to Figure 2 of the first embodiment according to 1, characterized in that at the outer vertices A intersecting tunnel tubes 1 ', 1 ", 2', 2 "so much soil is removed that a turn-off lane 9 is formed over which the Vehicles from the delivering tunnel tube, e.g. 1 ', into the evacuating tunnel tube, e.g. 2 " can turn without entering the roundabout itself. This arrangement is the Avoidance of accidents. Here are traffic measures to be provided, the one prescribe early positioning of the turning traffic in the right lane.

Gegenstand der Erfindung ist auch ein Verfahren zur Herstellung einer derartigen Straßentunnelanordnung, welches insbesondere vorsieht, dass zunächst die Straßentunnelröhren 1', 1", 2', 2" mit geradeaus führenden, einfachen und aus dem bisherigen Tunnel- und Bergbau bekannten Tunnelbohrmaschinen gefertigt werden. Bei diesen Maschinen handelt es sich insbesondere um Schildvortriebsmaschinen. Nach Fertigstellung dieses Rohbaus werden die Kreisverkehranordnungen durch Abtragen des Erdreichs an den Außenseiten, also zwischen den einzelnen Tunnelröhren, und durch Abrundungen im Bereich der Eckpunkte A erzeugt und die Oberflächen verfestigt, sowie der Fahrbahnbelag eingebracht. Das Verfahren hat den Vorteil, dass mit einfachen, bekannten Maschinen gearbeitet werden kann und keine zusätzlichen Aufwendungen erforderlich sind, um die gesamte Kreisverkehranordnung abzustützen, weil der verbleibende Block (Quadrat 4) diese Abstützungsfunktion auf natürliche Weise übernimmt.The invention also provides a process for producing such a process Road tunnel arrangement, which provides in particular that the first Street tunnels 1 ', 1 ", 2', 2" with straight ahead, simple and out of the past Tunneling and mining known tunnel boring machines are manufactured. In these Machines are especially shield tunneling machines. After completion This shell, the roundabout arrangements by removing the soil to the Outer sides, so between the individual tunnel tubes, and by rounding in the area creates the vertices A and solidifies the surfaces, as well as the road surface brought in. The procedure has the advantage that with simple, well-known machines can be worked and no additional expenses are required to the support entire roundabout arrangement because the remaining block (square 4) this Support function in a natural way.

Alternativ zu den vorgeschlagenen Ausführungsbeispielen ist es auch möglich, die Tunnelröhren 2', 2" des zweiten Paars 2 in einem anderen Abstand voneinander zu führen als die Tunnelröhren 1', 1" des ersten Paars 1. In diesem Fall ist das zentrale Rechteck 4 kein Quadrat und es ergibt sich auch keine Kreisverkehr-, sondern eine Ringverkehranordnung, die etwa die Form einer Ellipse hat.As an alternative to the proposed embodiments, it is also possible to Tunnel tubes 2 ', 2 "of the second pair 2 at a different distance from each other than the tunnel tubes 1 ', 1 "of the first pair 1. In this case, the central rectangle 4 is not Square and there is no roundabout, but a ring traffic arrangement, the about the shape of an ellipse.

Kreisverkehranordnungen befinden. Ein solches Tunnelnetzwerk verläuft vorzugsweise in einer Tiefe unterhalb der Ver- und Entsorgungssysteme und der übrigen Verkehrssysteme (z.B. U- und S-Bahn) des Ballungsraums, also in etwa 30 - 50 m unter der Erdoberfläche. Die verkehrsmäßige Erschließung von außen kann durch eine Ringstraße entlang der Peripherie des Ballungsraumes erfolgen, an welche die Tunnelröhren in geeigneter und an sich bekannter Weise straßenverkehrsmäßig angebunden sind. Es können auch mehrere Ringstraßen in verschiedenem Abstand von Zentrum des Ballungsraumes vorgesehen sein, wobei mindestens eine dieser Ringstraßen in einem Tunnel angeordnet sein kann. Vorzugsweise weist ein solches Tunnelnetzwerk auch eine Vielzahl unterirdischer, über die Tunnelröhren straßenverkehrsmäßig erschlossener Parkgaragen mit Zugangsvorrichtungen für Personen und Güter, z.B. Treppen und Aufzüge, zur Oberfläche des Ballungsraumes auf, welche auch Anschlussstellen für den öffentlichen Personennahverkehr und den Fernverkehr erschließen können.Preferably, the road tunnel arrangement according to the invention within a Road tunnel network used for the traffic development of agglomerations, where then a plurality of pairs 1 and 2 are provided, all parallel or vertical which may result in a checkerboard pattern of road tunnels whose intersection points are the ring or roundabout arrangements according to the invention are located. Such a tunnel network preferably runs at a depth below the and disposal systems and other transport systems (eg subway and suburban train) of the Agglomeration, ie about 30 - 50 m below the surface of the earth. The traffic Unlocking from the outside can be done by a ring road along the periphery of the Conurbation done, to which the tunnel tubes in a suitable and known per se Way are taut road traffic.
