Description

Die Erfindung betrifft ein Verfahren zum Entlasten eines in einem Wegekörper eingebauten Einbauteils von Kräften, die von einer Oberfläche des Wegekörpers in diesen eingeleitet werden, durch Einlegen einer Grundplatte in einen Bereich eines oberen Teils des Einbauteils. Darüber hinaus betrifft die Erfindung einen Schacht aus mehreren in einem Wegekörper aufeinander stehenden Ringen, der zu einer Begrenzung einer in dem Wegekörper eingerichteten Baugrube abgestützt ist und sich in Richtung auf eine Wegeoberfläche einseitig konisch zu einem eine Öffnung umgebenden Rand verjüngt, die von einer Schachtabdeckung verschließbar ist, wobei in Richtung von einwirkenden Kräften oberhalb des Randes eine die auftretenden Kräfte aufnehmende Grundplatte vorgesehen ist.The invention relates to a method for relieving a built-in a path body built-in part of forces that are introduced from a surface of the path body in this, by inserting a base plate in an area of an upper part of the insert. In addition, the invention relates to a shaft of several successive rings in a path body, which is supported to a boundary of a constructed in the path body excavation and tapering towards a road surface on one side conically to an opening surrounding edge, which can be closed by a manhole cover is, is provided in the direction of acting forces above the edge of the forces occurring receiving base plate.

Aus der deutschen Patentschrift 32 21 031 ist ein Straßenschacht bekanntgeworden, bei dem der obere Schachthohlraum von Steinen umgeben ist, deren Innenkontur dem Schachthohlraum angepaßt ist. Dabei sind die Steine, vorzugsweise Betonsteine, als Formsteine ausgebildet, deren Innenkonturen je nach Art des Schachtes rund oder abgewinkelt sind. Diese Formsteine sind in eine Betonschicht eingesetzt. Derartige Schächte haben sich hervorragend bewährt und als sehr verschleißfest erwiesen.From the German patent 32 21 031 a shaft has become known, in which the upper shaft cavity is surrounded by stones whose inner contour is adapted to the shaft cavity. In this case, the stones, preferably concrete blocks, formed as shaped stones whose inner contours are round or angled depending on the type of shaft. These conglomerates are inserted in a concrete layer. Such manholes have proven to be excellent and proved to be very resistant to wear.

Im Zuge starkt zunehmender Belastungen öffentlicher Wege, insbesondere von Straßen, hat sich erwiesen, daß erhebliche Schäden im Bereich von Einbauteilen dadurch entstanden sind, daß die von den Fahrzeugen im Bereich der Einbauteile erzeugten Kräfte nicht weitflächig genug in einen das Einbauteil umgebenden Untergrund eingeleitet werden konnten. Vielmehr stellte sich heraus, daß der das Einbauteil umgebende Untergrund unter dem Einfluß der in ihn eingeleiteten Kräfte sich im Laufe der Zeit verdichtete und unter dem Einfluß dieser Verdichtung nachgab. Dadurch lag das das Einbauteil umgebende Material nicht mehr gleichmäßig verteilt im Bereich des Einbauteils, so daß Lockerungen und Verschiebungen im Material auftraten, die sich bis zur Oberfläche des Wegekörpers bemerkbar machten. Die Oberfläche brach ein, so daß eine gleichmäßige Abstützung des Einbauteils bezüglich des Wegekörpers nicht mehr gewährleistet war. Eine Reparatur des Wegekörpers im Bereich des Einbauteils erwies sich als unerläßlich.In the wake of increasing loads of public roads, especially roads, it has been proven that considerable damage in the field of built-in parts have arisen that the forces generated by the vehicles in the field of installation parts could not be initiated far enough in a subsoil surrounding the mounting part , Rather, it turned out that the substrate surrounding the fixture under the influence of the forces introduced into it compressed over time and gave way under the influence of this compression. As a result, the material surrounding the fixture was no longer evenly distributed in the region of the fixture so that loosening and displacements occurred in the material, which made itself felt to the surface of the body path. The surface broke, so that a uniform support of the insert with respect to the body path was no longer guaranteed. A repair of the path body in the area of the built-in proved to be indispensable.

Aus der deutschen Gebrauchsmusterschrift DE 295 21 453 U1 (Burkhardt) ist das Verfahren und der Schacht bekannt, zum Entlasten eines in einem Wegekörper eingebauten Einbauteils eine Platte in einem Bereich eines oberen Teils des Einbauteils vorzusehen. Über diese Platten wurden Kräfte in das das Einbauteil umgebende Erdreich eingeleitet. Dabei wurde das Erdreich durch die vom vorüber fahrenden Verkehr ausgehende wechselnde Belastung zunehmend verdichtet. Aufgrund dieser Verdichtung sank nicht nur die Platte sondern auch die gesamte Schachtabdeckung gegenüber einer Oberfläche des Straßenaufbaus ab. Die auf diese Weise entstehende Vertiefung im Straßenaufbau wurde dadurch erheblich vergrößert, dass die Reifen vorüber fahrender Fahrzeuge in die Vertiefung einbrachen. Die auf diese Weise entstehende Schädigung des Straßenaufbaus macht eine umfangreiche Sanierung des gesamten Schachtes erforderlich.From the German Utility Model DE 295 21 453 U1 (Burkhardt), the method and the shaft is known to provide a plate in an area of an upper part of the insert for relieving a built-in a body member mounting plate. Forces were introduced into the soil surrounding the built-in part via these plates. In doing so, the soil was increasingly compacted by the changing load resulting from passing traffic. Due to this compaction, not only the slab but also the entire manhole cover dropped off against a surface of the road structure. The resulting depression in the road construction was considerably increased by the fact that the tires of passing vehicles broke into the depression. The resulting damage to the road construction requires extensive renovation of the entire shaft.

Aufgabe der vorliegenden Erfindung ist es daher, das Einbauteil im Wegekörper so einzubauen, dass die in seinem Bereich auftretenden Kräfte gleichmäßig in einen das Einbauteil umgebenden Untergrund eingeleitet werden können.The object of the present invention is therefore to install the installation part in the path body in such a way that the forces occurring in its area can be introduced uniformly into a substrate surrounding the installation part.

Diese Aufgabe wird mit dem erfindungsgemäßen Verfahren dadurch gelöst, dass das Einbauteil im Bereich seines oberen Teils mit einer Schicht aus Stützmaterial zur Ausbildung eines tragenden Fundaments umgeben wird, in dem die massiv ausgebildete Grundplatte oberhalb des Einbauteils abgestützt wird.This object is achieved by the method according to the invention in that the mounting part is surrounded in the region of its upper part with a layer of support material to form a supporting foundation in which the solid base plate is supported above the mounting part.

Mit diesem Verfahren wird erreicht, dass nicht nur statische Belastungen von dem Einbauteil ferngehalten werden, sondern darüber hinaus auch dynamische Kräfte aufgrund von Schwingungen, die vom Straßenverkehr erzeugt werden. Diese Stabilität erweist sich insbesondere im Hinblick auf die ständig wachsenden Gewichte, die auf Straßen befördert wer-den, als besonders widerstandsfähig. Die in die Baugrube eingebrachte Platte besitzt nicht nur eine hohe Widerstandskraft gegen Zerbrechen, sondern dämpft auch aufgrund ihres Gewichtes die in sie eingeleiteten Kräfte, bevor diese an den die Platte abstützenden Untergrund weitergegeben werden. Diese starke Dämpfung erweist sich insbesondere auch dann als die Struktur des Schachtes erhaltend, wenn aufgrund einer hohen Verkehrsdichte ständig Schwingungen in die Straße eingeleitet werden. Zur Dämpfung dieser Schwingungen besitzt die Platte eine große Masse. Sie wird relativ dick ausgebildet, so dass sie mit üblichen Fortbewegungsmitteln gerade noch bewegt werden kann. Sie überragt den Rand des Schachtes und liegt zu wesentlichen Teilen auf einem den Schacht umgebenden Fundament auf. Dadurch werden die eingeleiteten Kräfte ohne Gefährdung des Schachtes in den Untergrund abgeleitet.This method ensures that not only static loads are kept away from the built-in part, but also dynamic forces due to vibrations generated by road traffic. This stability is particularly evident in view of the ever-increasing weights being transported on the roads, as particularly resistant. The introduced into the excavation plate not only has a high resistance to breakage, but also attenuates due to their weight, the forces introduced into them before they are passed on to the plate supporting the ground. This strong damping proves to be particularly as the structure of the shaft preserving, if due to a high traffic density constantly vibrations are introduced into the street. To dampen these vibrations, the plate has a large mass. It is made relatively thick, so that it can be just moved with conventional means of transport. It towers over the edge of the shaft and lies substantially on a foundation surrounding the shaft. As a result, the introduced forces are discharged into the ground without endangering the shaft.

Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung wird auf die Grundplatte eine kraftübertragende Auflage aufgebracht, die in eine den Wegekörper begrenzende Oberfläche einmündet. Zu diesem Zweck werden Auflageringe benutzt, die auch in rechteckiger Form hergestellt werden. Sie liegen möglichst großflächig auf der unter ihnen angeordneten Grundplatte auf.According to a further preferred embodiment of the invention, a force-transmitting support is applied to the base plate, which opens into a surface limiting the body. For this purpose, support rings are used, which are also produced in a rectangular shape. They are as large as possible on the base plate arranged below them.

Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung ist das Fundament durch eine Fundamentenplatte in Richtung der eingeleiteten Kräfte nach oben begrenzt, die mindestens Teile des Einbauteils mit einer Ausnehmung umschließt. Zu diesem Zwecke besitzt die Fundamentenplatte eine Mittelöffnung, die über einen die Öffnung eines Schachtes umgebenden Rand geschoben wird, bis die Platte knapp oberhalb einer oberen Begrenzung des Randes mit ihrer Oberfläche verläuft. Dadurch ist gewährleistet, dass die gesamten Belastungen, die von der Grundplatte aufgenommen und abgeleitet werden, nicht in den Schacht, sondern über die Fundamentenplatte abgeleitet werden.According to a further preferred embodiment of the invention, the foundation is bounded by a foundation plate in the direction of the introduced forces upwards, which encloses at least parts of the mounting part with a recess. For this purpose, the foundation plate has a central opening which is pushed over an edge surrounding the opening of a shaft until the plate runs just above an upper boundary of the edge with its surface. This ensures that the entire loads that are absorbed and derived from the base plate, are not derived in the slot, but on the foundation plate.

Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung wird durch die Fundamentenplatte eine auf die Grundplatte auftreffende Belastung vor Eintritt in das Fundament weiter gedämpft. Durch das hohe Gewicht der Grundplatte einerseits und der Fundamentenplatte andererseits kommt eine starke Dämpfung der in den Straßenkörper eingeleiteten Schwingungen zustande.According to a further preferred embodiment of the invention, a load applied to the base plate before entry into the foundation is further damped by the foundation plate. Due to the high weight of the base plate on the one hand and the foundation plate on the other hand comes a strong damping of the vibrations introduced into the road body.

Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung wird durch die Fundamentenplatte die auf die Grundplatte auftreffende Belastung weiterhin über den gesamten Querschnitt der Baugrube verteilt. Dadurch ist gewährleistet, dass die gesamten Belastungen nicht in den Schacht, sondern sowohl über die Grundplatte als auch über die Fundamen-tenplatte in das Fundament abgeleitet werden. Dadurch wird insbesondere der sehr gefährdete obere Rand des Schachtes geschont.According to a further preferred embodiment of the invention, the load applied to the base plate is distributed over the entire cross section of the excavation by the foundation plate. This ensures that the entire load is not in the shaft, but both on the base plate and on the foundation plate be derived in the foundation. As a result, in particular the very vulnerable upper edge of the shaft is spared.

Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung überragt die Grundplatte den Rand des Schachtes. Dadurch werden die in den Straßenkörper eingeleiteten Kräfte über die Grundplatte in den Untergrund abgeleitet.According to a further preferred embodiment of the invention, the base plate projects beyond the edge of the shaft. As a result, the forces introduced into the road body are dissipated via the base plate into the ground.

Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung wird zwischen der Grundplatte einerseits und der Fundamentplatte und/oder den Auflageringen andererseits eine elastische Zwischenlage angeordnet. Diese ist derart ausgebildet, dass sie auch den erheblichen Schwingungsbelastungen Rechnung tragen kann, die von vorüber fahrenden Fahrzeugen erzeugt werden.According to a further preferred embodiment of the invention, an elastic intermediate layer is arranged between the base plate on the one hand and the foundation plate and / or the Auflageringen on the other hand. This is designed so that it can also take into account the significant vibration loads generated by passing vehicles.

Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung sind die elastischen Zwischenlagen mit der Grundplatte, der Fundamentplatte und/oder den Auflagenringen fest verbunden. Derartige Zwischenlagen sind entweder in die Grundplatte, die Festplatte und/oder die Auflageringe integriert oder auf deren Oberfläche befestigt.According to a further preferred embodiment of the invention, the elastic intermediate layers with the base plate, the foundation plate and / or the support rings are firmly connected. Such intermediate layers are either integrated in the base plate, the hard disk and / or the Auflageringe or attached to the surface.

Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung werden die elastischen Zwischenlagen über die gesamten sich gegenseitig beaufschlagenden Flächen aufgebracht. Auf diese Weise erhalten sie eine große kraftübertragende Oberfläche, so dass sie geeignet sind, die Kräfte zu übertragen, ohne selbst vorzeitig Schaden zu nehmen.According to a further preferred embodiment of the invention, the elastic intermediate layers are applied over the entire mutually acting surfaces. In this way, they get a large force-transmitting surface, so that they are capable of transmitting the forces, without premature damage themselves.

Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung werden die elastischen Zwischenlagen nur teilweise auf die Flächen der Grundplatte, der Festplatte und/oder der Auflageringe aufgebracht. Diese teilweise Aufbringung hat den Vorteil, dass auf diese Weise das Schwingungsverhalten der Grundplatte, der Festplatte und/oder der Ringe am besten beeinflusst werden kann.According to a further preferred embodiment of the invention, the elastic intermediate layers are only partially applied to the surfaces of the base plate, the hard disk and / or the support rings. This partial application has the advantage that in this way the vibration behavior of the base plate, the hard disk and / or the rings can best be influenced.

Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung wird durch die Fundamentenplatte die auf die Grundplatte auftreffende Belastung über den gesamten Querschnitt der Baugrube verteilt. Zu diesem Zweck wird eine den Schacht umgebende Betonschicht hergestellt, in der die Fundamentenplatte abgestützt wird. Diese Kombination von Fundamentenplatte, Grundplatte und Betonschicht schafft eine Gesamtheit sehr schwerer und damit stark dämpfender Bauteile, die ein hohes Trägheitsmoment besitzen.According to a further preferred embodiment of the invention, the load on the base plate is distributed over the entire cross section of the excavation by the foundation plate. For this purpose, a concrete layer surrounding the shaft is made, in which the foundation plate is supported. This combination of foundation plate, base plate and concrete layer creates a total of very heavy and thus strongly damping components that have a high moment of inertia.

Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung wird die Grundplatte gegenüber der Fundamentenplatte elastisch abgestützt. Dazu sind elastische Zwischenlagen vorgehen, die derart ausgebildet sind, dass sie auch den erheblichen Schwingungsbelastungen Rechnung tragen können, die von vorüber fahrenden Fahrzeugen erzeugt werden. Deswegen werden zwischen den einzelnen Teilen eines Schachtbauwerks elastische Materialen verwendet, die einerseits geeignet sind, hohe Belastungen zu übertragen, andererseits vom Schachtbauwerk Schwingungen abzuhalten.According to a further preferred embodiment of the invention, the base plate is elastically supported relative to the foundation plate. For this purpose, elastic intermediate layers proceed, which are designed such that they can take into account the considerable vibration loads generated by passing vehicles. Therefore, elastic materials are used between the individual parts of a shaft structure, which are on the one hand suitable to transfer high loads, on the other hand to prevent vibrations from the shaft structure.

Hinsichtlich des Schachtes wird die erfindungsgemäße Aufgabe dadurch gelöst, dass die Grundplatte mit einer der Öffnung des Schachtes entsprechenden Ausnehmung versehen und massiv ausgebildet ist und oberhalb des Randes auf einem Stützmaterial großflächig aufliegt, das den Schacht zu einer Ableitung der auftretenden Kräfte in eine dem Rand benachbarte Fläche umgibt. Durch diese Ausgestaltung der Grundplatte ist gewährleistet, dass die auftretenden Kräfte nicht auf den Schacht einwirken und diesen zerstören. Vielmehr werden die Kräfte durch die massiv ausgebildete Grundplatte in das Stützmaterial abgeleitet, das den Schacht umgibt. Die massive Ausbildung der Grundplatte und des Stützmaterials bewirken eine Dämpfung der auftretenden dynamischen Kräfte, so dass das den Schacht umgebende Material nicht weiter verdichtet wird sondern in einer Einbaulage verharrt.With regard to the shaft, the object of the invention is achieved in that the base plate provided with a corresponding opening of the shaft recess and is solid and above the edge of a support material over a large area rests, which adjacent the shaft to a derivative of the forces occurring in a the edge Surrounding area. This design of the base plate ensures that the forces do not act on the shaft and destroy it. Rather, the forces are derived by the solid base plate in the support material that surrounds the shaft. The massive formation of the base plate and the support material cause a damping of the dynamic forces that occur, so that the material surrounding the shaft is not further compressed but remains in an installed position.

Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung wird die Grundplatte auf einer Betonschicht abgestützt. Diese gewährt nicht nur die Widerstandskraft, um die Grundplatte dauerhaft in der Einbaulage zu halten, sondern darüber hinaus auch aufgrund ihres hohen Gewichts eine hohe Trägheit, die eine Dämpfung der hohen dynamischen Beanspruchung gewährleistet.According to a further preferred embodiment of the invention, the base plate is supported on a concrete layer. This not only provides the resistance to keep the base plate permanently in the installed position, but also because of their high weight high inertia, which ensures a damping of high dynamic stress.

Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung ist die Grundplatte auf der Fundamentplatte abgestützt. Auch diese besitzt ein hohes Gewicht und eine dauerhafte Abstützung auf dem in die Baugrube eingebrachten Fundament.According to a further preferred embodiment of the invention, the base plate is supported on the foundation plate. This also has a high weight and a permanent support on the introduced into the excavation foundation.

Die Figuren zeigen einen im Querschnitt kreisrunden Schacht (1), dessen Hohlraum (2) von Schachtringen (3, 15) umgeben ist. Diese Schachtringe (3, 15) bestehen im wesentlichen aus Beton. Ein nur teilweise dargestellter unterer Schachtring (15) ist zylindrisch ausgebildet, während ein den Schacht (1) nach oben hin abschließender Schachtring (3) jeweils zur Hälfte seiner Wandungen (16) einen zylindrischen Teil (17) und einen konischen Teil (18) aufweist. Der Schacht (1) und die Schachtringe (3, 15) können jedoch auch andere übliche Konfigurationen aufweisen, z.B. einen quadratischen, rechteckigen oder ovalen Querschnitt. Sie können auch aus einem anderen Material als Beton, z.B. Kunststoff bestehen.The figures show a circular cross-section shaft (1), the cavity (2) of chess rings (3, 15) is surrounded. These manhole rings (3, 15) consist essentially of concrete. A partially shown lower manhole ring (15) is cylindrical, while a manhole (1) has a cylindrical part (17) and a conical part (18) in each case half of its walls (16) towards the top end of the shaft ring (3). However, the shaft (1) and the manhole rings (3, 15) can also have other conventional configurations, for example a square, rectangular or oval cross-section. They can also consist of a different material than concrete, eg plastic.

Auf einer die Schachtringe (3, 15) umgebenden Schicht (4) aus Beton, Kies, Granulat, Recyclingmaterial oder aus einer elastischen Masse, die auf darunter befindlichem verdichteten Sand (6) ruht, liegt eine Fundamentenplatte (7) auf, die ihrerseits eine Grundplatte (8) trägt. Bei der flexiblen Bauweise (Figuren 2, 3, 13) liegt zwischen einem den Schachtring (3) abschließenden oberen Rand (19) bzw. einer von diesem Rand (19) gebildeten Auflagefläche (14) und der Grundplatte (8) eine elastische Fuge (9), die sich unter dem Einfluss einer von oben auf den Schacht (1) einwirkenden Belastung elastisch verformt. Eine weitere elastische Fuge (20) kann auch bei der flexiblen Bauweise zwischen dem konischen Teil (18) des Schachtrings (3) und der Fundamentenplatte (7) vorgesehen sein. Ferner sind bei der flexiblen Bauweise noch elastische Fugen (47) zwischen einem einen Schachtdeckel (21) abstützenden Schachtrahmen (22) und einem oberen Auflagering (23) vorgesehen, der sich über einen unteren Auflagering (24) auf der Grundplatte (8) abstützt.On a the chess rings (3, 15) surrounding layer (4) of concrete, gravel, granules, recycled material or an elastic mass, which rests on underneath compacted sand (6), is a foundation plate (7), which in turn a Base plate (8) carries. In the flexible construction ( Figures 2 . 3 . 13 ) lies between an upper edge (19) terminating the shaft ring (3) or a bearing surface (14) formed by this edge (19) and the base plate (8) is an elastic joint (9), which is under the influence of a from above on the shaft (1) acting load elastically deformed. A further elastic joint (20) can also be provided in the flexible construction between the conical part (18) of the manhole ring (3) and the foundation plate (7). Furthermore, elastic joints (47) between a shaft cover (21) supporting manhole frame (22) and an upper support ring (23) are provided in the flexible construction, which is supported on a lower support ring (24) on the base plate (8).

Die Fundamentenplatte (7) stützt sich in der Schicht (4) aus Beton, Kies, Granulat, Recyclingmaterial oder elastischer Masse ab. Diese Schicht (4) begrenzt auch auf ihrer dem Hohlraum (2) abgewandten Außenseite (25) die Grundplatte (8) sowie die Außenseiten (26, 27) der Auflageringe (23, 24). Diese beiden Auflageringe (23, 24) werden bei der Ausführungsform mit Schnellmörtel durch Schnellmörtelfugen (28, 29) mit dem jeweils benachbarten Teil, dem unteren Auflagering (24) bzw. der Grundplatte (8) verbunden. Die Fundamentenplatte (7), die Grundplatte (8) sowie die Auflageringe (23 bzw. 24) können bei Verwendung der Betonbauweise auch über Mörtelfugen (30, 31, 32, 33) miteinander verbunden sein. Dabei wird zwischen dem Schachtrahmen (22) und dem oberen Auflagering (23) ein runder Auflagering (35) verwendet, zwischen dem und dem Schachtrahmen (22) einerseits und dem oberen Auflagering (23) jeweils Mörtelfugen vorgesehen sein können. Darüber hinaus liegt die Betonschicht (4) großflächig auf einer Schräge (46) des konisch in Richtung auf den oberen Rand (19) zulaufenden Teils (18) auf. Durch diese großflächige Auflage werden die Kräfte aus der Betonschicht (4) auf eine große Fläche der Schräge (46) verteilt, so dass diese von punktuellen Belastungen verschont wird.The foundation plate (7) is supported in the layer (4) of concrete, gravel, granules, recycled material or elastic mass. This layer (4) also delimits the base plate (8) and the outer sides (26, 27) of the support rings (23, 24) on its outer side (25) facing away from the cavity (2). These two Auflageringe (23, 24) are in the embodiment with quick mortar by Schnellmörtelfugen (28, 29) with the respective adjacent part, the lower support ring (24) and the Base plate (8) connected. The foundation plate (7), the base plate (8) and the Auflageringe (23 or 24) can be connected together using mortar joints (30, 31, 32, 33) when using the concrete construction. In this case, between the manhole frame (22) and the upper Auflagering (23) a round support ring (35) is used, between which and the manhole frame (22) on the one hand and the upper support ring (23) mortar joints may be provided. In addition, the concrete layer (4) over a large area on a slope (46) of the tapered towards the upper edge (19) tapered portion (18). By this large-scale edition, the forces from the concrete layer (4) are distributed over a large area of the slope (46), so that it is spared from punctual loads.

In den feuchten Beton der Betonschicht (4) bzw. in den Kies, das Granulat, das Recyclingmaterial oder in elastische Masse werden Steine (12) eingesetzt, zwischen denen und dem Schachtrahmen (22) auch bei Verwendung der starren Bauweise elastische Fugen (36) vorgesehen sind. Diese können aus einer geeigneten Gussmasse, z. B. einer Asphaltmasse, bestehen. Die Steine erstrecken sich um den Schachtrahmen (22) und sind dessen Konfiguration angepasst. Bei Verwendung eines kreisförmigen Schachtrahmens (22) besitzen auch die Steine (12) auf ihrer dem Schachtrahmen (22) zugewandten Seite (37) Gestaltungen in Form von Kreissegmenten, die dem Schachtrahmen (22) angepasst sind, so dass die Seiten (37) bei Verwendung eines kreisförmigen Schachtrahmens (22) auf einem entsprechenden Kreisbogen liegen, während bei Verwendung eines ovalen Schachtrahmens die Seiten (37) eine ovale Krümmung besitzen. Bei Verwendung rechteckiger Schachtrahmen (22) sind auch die diesem Schachtrahmen zugewandten Seiten (37) auf geraden Ebenen angeordnet. Die Steine (12) können auch in eine Schicht aus Schnellmörtel oder aus elastischer Vergussmasse eingelegt werden.In the wet concrete of the concrete layer (4) or in the gravel, granules, recycled material or in elastic mass stones (12) are used, between which and the manhole frame (22) even when using the rigid construction elastic joints (36) are provided. These can be made of a suitable casting material, for. As an asphalt mass exist. The stones extend around the manhole frame (22) and are adapted to its configuration. When using a circular manhole frame (22) also have the stones (12) on its the manhole frame (22) facing side (37) designs in the form of circle segments, which are the manhole frame (22) adapted so that the sides (37) Use of a circular manhole frame (22) lie on a corresponding circular arc, while using an oval manhole frame, the sides (37) have an oval curvature. When using rectangular manhole frame (22) and the manhole frame facing sides (37) are arranged on straight planes. The stones (12) can also be placed in a layer of quick mortar or elastic potting compound.

Zur Beschleunigung der Schachtbauweise werden die Steine (12) in Schnellmörtel (38) eingelegt. Dieser Schnellmörtel (38) besitzt den Vorteil, dass er erheblich schneller aushärtet als der Beton der Betonschicht (4). Soweit zur Aufnahme der auftretenden Belastungen eine Betonschicht (4) nicht notwendig ist, kann für die Freigabe eines sanierten Schachtes dadurch viel Zeit gewonnen werden, dass die Steine (12) in schnell aushärtenden Mörtel (38) eingelegt werden. Dieser härtet so schnell aus, dass die gesamte Baustelle relativ kurzfristig wieder dem Verkehr übergeben werden kann.To accelerate the shaft construction, the stones (12) in quick mortar (38) are inserted. This quick mortar (38) has the advantage that it hardens much faster than the concrete of the concrete layer (4). As far as a concrete layer (4) is not necessary to accommodate the loads occurring, a lot of time can be gained for the release of a rehabilitated shaft, that the stones (12) in fast-curing mortar (38) are inserted. This hardens so quickly that the entire construction site can be returned to traffic at relatively short notice.

Bei einem Schacht (1) gemäß der Erfindung kann es sich z. B. um einen Zugangsschacht für die Kanalisation, um einen Wasserablauf oder um einen Zugangsschacht für einen Schieber für Wasserleitungen (Hydrant) oder andere unterirdische Leitungen handeln. Bei einer Variante der Erfindung kann die Betonschicht zwischen der Grundplatte (8) und den Steinen (12) dadurch ersetzt werden, dass die Grundplatte (8) am Ort ihres geplanten Einsatzes aus Beton oder einer aushärtbaren Kunststoffmasse hergestellt wird und die Steine in die feuchte Masse eingesetzt werden, in der sie nach dem Aushärten festen Halt finden.In a shaft (1) according to the invention, it may, for. This may be, for example, an access shaft for sewerage, a drain or an access shaft for a hydrant or other underground lines. In a variant of the invention, the concrete layer between the base plate (8) and the stones (12) can be replaced by making the base plate (8) at the location of its intended use of concrete or a hardenable plastic mass and the stones into the wet mass be used, in which they find a firm hold after curing.

Die Fundamentenplatte (7) ist an mindestens zwei Stellen mit Durchgangslöchern (39, 40) versehen, die sich quer durch die Fundamentenplatte (7) von deren Unterfläche (41) zu deren Oberfläche (42) erstrecken. Diese Durchgangslöcher (39, 40), von denen zweckmäßigerweise vier Stück im Bereich der die Fundamentenplatte (7) begrenzenden vier Ecken vorgesehen sind, besitzen einen Querschnitt, der gross genug ist, um Hilfswerkzeuge, beispielsweise nicht dargestellte Heber, von der Oberfläche (42) zur Unterfläche (41) hindurchzustecken, die die Unterfläche (41) ergreifen. Zusätzlich können in den Durchgangslöchern (39, 40) noch Halterungen vorgesehen sein, die ein Anschlagen von Hebezeugen erleichtern. Diese Halterungen können als Stifte ausgebildet sein, die sich quer zur Längsrichtung der Durchgangslöcher (39, 40) durch diese erstrecken. Sie können allerdings auch an beliebigen Stellen der Platte als Vertiefungen der Plattenoberfläche ausgebildet sein, durch die sich Stifte zum Anschlagen von Hebezeugen erstrecken. Allerdings können in die Durchgangslöcher (39, 40) auch Gewinde eingegossen werden, in die entsprechende Schraubtransportösen eingeschraubt werden können.The foundation plate (7) is provided with at least two locations with through holes (39, 40) extending transversely through the foundation plate (7) from the lower surface (41) to the surface (42) thereof. These through-holes (39, 40), of which four are expediently provided in the region of the four corners delimiting the foundation plate (7), have a cross-section which is large enough to allow auxiliary tools, for example lifters not shown, to be removed from the surface (42). to the lower surface (41), which engage the lower surface (41). In addition, in the through holes (39, 40) still brackets may be provided, the facilitate lifting of hoists. These brackets may be formed as pins which extend transversely to the longitudinal direction of the through holes (39, 40) therethrough. However, they can also be formed at any point on the plate as depressions of the plate surface, through which extend pins for striking lifting equipment. However, in the through holes (39, 40) and threaded, can be screwed into the corresponding Schraubtransportösen.

Sodann kann die Fundamentenplatte mit Hilfe der Heber ergriffen und in die noch weiche Betonschicht (4) so eingebettet werden, dass die Oberfläche (42) die Auflagefläche (14) des konischen Teils (18) ein wenig, beispielsweise um etwa einen Zentimeter überragt. Dabei ist beabsichtigt, dass die noch weiche Betonmasse beim Absenken der Fundamentenplatte (7) in den Durchgangslöchern (39, 40) in Richtung auf die Oberfläche (42) aufsteigt und in dem Bereich der Oberfläche (42) einen Verschluss (43) bildet, so dass die in den Durchgangslöchern (39, 40) aushärtende Betonmasse Dübel bildet, die eine feste Lage der Fundamentenplatte (7) an der Stelle ihrer Absenkung in die Betonschicht (4) garantieren. Sodann kann auf die Auflagerfläche (14) und auf die Oberfläche (42) je nach dem jeweiligen Bedarfsfall Schnellmörtel oder eine elastische Fuge (9) aufgebracht werden, mit der die Grundplatte (8) verbunden wird.Then, the foundation plate can be grasped with the aid of the lifter and embedded in the still soft concrete layer (4) so that the surface (42) slightly surmounts the bearing surface (14) of the conical part (18), for example by about one centimeter. It is intended that the still soft concrete mass rises when lowering the foundation plate (7) in the through holes (39, 40) in the direction of the surface (42) and in the region of the surface (42) forms a closure (43), so that in the through holes (39, 40) hardening concrete mass forms dowels that guarantee a firm position of the foundation plate (7) at the point of their lowering into the concrete layer (4). Then can be applied to the support surface (14) and on the surface (42) depending on the particular case of need quick mortar or elastic joint (9), with the base plate (8) is connected.

Statt einer elastischen Fuge (9) kann zwischen der Auflagefläche (14) und der Grundplatte (8) auch ein elastischer Ring (60) vorgesehen sein, über den die Grundplatte (8) elastisch auf der Auflagefläche (14) gelagert werden kann. Zur eindeutigen Führung des elastischen Ringes (60), der entweder die gesamte Auflagefläche (14) oder nur Teile dieser Auflagefläche (14) bedeckt, kann die Fundamentenplatte (7) mit ihrer Oberfläche (42) die Auflagefläche des Schachtringes (3) soweit überragen, dass von der Fundamentenplatte (7) eine den elastischen Ring (60) führende Aufnahme gebildet wird. Dabei wird der elastische Ring (60) so bemessen, dass er die Oberfläche (42) der Fundamentenplatte soweit überragt, dass die Grundplatte (8) mit ihrer der Auflagefläche (14) zugewandten Unterseite den elastischen Ring (60) beaufschlagt und auf diesem elastisch gelagert ist. Darüber hinaus kann die Grundplatte (8) auf der Fundamentenplatte (7) mit einer elastischen Fuge (61) gelagert sein.Instead of an elastic joint (9) may be provided between the support surface (14) and the base plate (8) and an elastic ring (60) through which the base plate (8) can be elastically mounted on the support surface (14). For clear guidance of the elastic ring (60) covering either the entire support surface (14) or only parts of this support surface (14), the foundation plate (7) with its surface (42) the support surface of the manhole ring (3) so far project beyond that of the foundation plate (7) a resilient ring (60) leading to recording is formed. In this case, the elastic ring (60) is dimensioned so that it extends beyond the surface (42) of the foundation plate so far that the base plate (8) with its the support surface (14) facing underside of the elastic ring (60) acted upon and elastically mounted on this is. In addition, the base plate (8) can be mounted on the foundation plate (7) with an elastic joint (61).

Die elastischen Fugen (9, 26, 36, 47) können aus einer elastischen Haftmittelschicht, beispielsweise Asphalt bestehen. Darüber hinaus können elastische Fugen auch mit Hilfe von elastischem Material (48) ausgebildet sein, das beispielsweise in einen kreisförmigen oder eckigen Auflagering (45, 23, 24) eingelegt wird. Dabei kann das elastische Material (98) in Form eines in eine oder beide Oberflächen (49, 50) des Auflageringes (45, 23, 24) eingelegten Ringes ausgebildet sein. Der entsprechende Ring kann in Form von Teilstücken (51) über die Oberflächen (49, 50) verteilt sein. Es ist jedoch auch möglich, einen Auflagering zu benutzen, der einstückig parallel zu Begrenzungen (52, 53) des Auflageringes oder außermittig dazu verläuft.The elastic joints (9, 26, 36, 47) may consist of an elastic adhesive layer, for example asphalt. In addition, elastic joints may also be formed with the aid of elastic material (48), which is laid, for example, in a circular or angular support ring (45, 23, 24). In this case, the elastic material (98) in the form of a in one or both surfaces (49, 50) of the support ring (45, 23, 24) inserted ring may be formed. The corresponding ring may be distributed over the surfaces (49, 50) in the form of sections (51). However, it is also possible to use a support ring, which runs integrally parallel to boundaries (52, 53) of the support ring or eccentrically thereto.

Darüber hinaus kann auch ein loser Auflagering (54) zur flexiblen Lagerung Verwendung finden. Dieser wird beim Aufbau des Schachtes (1) zwischen die flexibel zu lagernden Teile, beispielsweise zwei Auflageringe (23, 24) beziehungsweise (23, 45) gelegt.In addition, a loose support ring (54) can be used for flexible storage. This is placed in the construction of the shaft (1) between the flexible parts to be stored, for example, two Auflageringe (23, 24) and (23, 45).

Schließlich ist es auch denkbar, eine Flexiblität des Schachtaufbaus dadurch zu erzeugen, dass ein Auflagering (45) Verwendung findet, der aus einem auf Druck belastbaren und trotzdem flexiblen Material (55) besteht. Dieses kann beispielsweise dadurch erzeugt werden, dass in eine tragfähige Masse (56) elastische Teile (57), beispielsweise Luftblasen, eingelagert werden. Die elastischen Teile (57) können jedoch auch aus einem elastischen Gummi- bzw. Kunststoffmaterial bestehen.Finally, it is also conceivable to create a flexibility of the shaft construction in that a support ring (45) is used which consists of a pressure-loadable, yet flexible material (55). This can for example be generated by the fact that in a sustainable Mass (56) elastic parts (57), such as air bubbles, are stored. However, the elastic parts (57) may also be made of an elastic rubber or plastic material.

In ähnlicher Weise ist ein aus mindestens zwei Lagen (58, 59) aufgebauter Auflagering (45) geeignet, die auftretenden Kräfte elastisch aufzunehmen und gegebenenfalls zu dämpfen. Dabei wechseln sich jeweils starre Lagen (58) mit elastischen Lagen (59) ab, die untereinander fest verbunden sind. Die elastischen Lagen (59) können beispielsweise aus einer elastischen Masse aus Gummi bzw. Kunststoff bestehen, die mit einer festen Masse jeweils verbunden ist. Durch diese aus mehreren Lagen (58, 59) bestehenden Ringe (45) kann deren Elastizität einem jeweils auftretenden Bedarfsfall optimal angepasst werden.Similarly, a bearing ring (45) made up of at least two layers (58, 59) is suitable for elastically absorbing and possibly damping the forces that occur. In each case, rigid layers (58) alternate with elastic layers (59), which are firmly connected to one another. The elastic layers (59) may for example consist of an elastic mass of rubber or plastic, which is connected to a solid mass respectively. By means of these rings (45) consisting of a plurality of layers (58, 59), their elasticity can be optimally adapted to any particular case of need.

Eine weitere Elastizität kann dadurch erzeugt werden, dass die Platten (7, 8) und Auflageringe (45) aus Kunststoff hergestellt werden. Dabei werden solche Kunststoffe verwendet, die entsprechend dem jeweiligen Einsatzfall der Platten (7, 8) bzw. Ringe (23, 24, 45) ausgesucht werden. Denkbar sind Kunststoffkombinationen, die einerseits dämpfende Eigenschaften besitzen und andererseits in der Lage sind, durch eine hohe Masse die auftretenden Belastungen vom Schacht (1) abzuhalten und gleichmäßig auf die den Schacht (1) umgebende Masse aus Beton (4) bzw. Sand (6) abzuleiten. Dabei werden je nach dem gewünschten Verhalten der Platten (7, 8) bzw. Ringe (23, 24, 45) weiche oder sehr harte Materialien verwendet, die aber in jedem Falle aufgrund ihrer Flexibilität dämpfend wirken können.Further elasticity can be produced by making the plates (7, 8) and support rings (45) of plastic. In this case, such plastics are used, which are selected according to the particular application of the plates (7, 8) or rings (23, 24, 45). Conceivable are plastic combinations, on the one hand have damping properties and on the other hand are able to keep the loads occurring from the shaft (1) by a high mass and evenly on the shaft (1) surrounding mass of concrete (4) or sand (6 ). Depending on the desired behavior of the plates (7, 8) or rings (23, 24, 45), soft or very hard materials are used which, however, can have a damping effect in any case due to their flexibility.
