Description
Die Erfindung betrifft ein Böschungsbauwerk gemäß dem Oberbegriff von Anspruch 1.The invention relates to a slope structure according to the preamble of
Im Stand der Technik sind verschiedene Böschungsbauwerke mit Lagen von Erdstoff, die jeweils ein luftseitiges Abschlusselement aufweisen, welche mit in den Erdstoff gerichtete Rückverankerungen verbunden sind, bekannt. Derartige Böschungsbauwerke werden nach einem als kunststoffbewehrte Erde bezeichneten System errichtet, worunter ein Verbundkörper aus Boden und einer Bewehrung verstanden wird. Als Bewehrung werden bevorzugt Stahl oder Kunststoffstäbe, Reibungsbänder, Matten oder Gitter aus Geokunststoff verwendet, welche bevorzugt horizontal angeordnet werden.In the prior art, various embankment structures with layers of earth, each having an air-side closure element, which are connected to the earth-directed rear anchorages known. Such embankment structures are built according to a designated as plastic reinforced earth system, which is understood as a composite body of soil and a reinforcement.

Nachteilig ist dabei, dass eine die Tragfähigkeit derartiger Böschungsbauwerke langfristig begünstigende Begrünung einer regelmäßigen Kontrolle bedarf und daher aufwendig ist.A disadvantage is that the sustainability of such embankment structures long-term favoring greening requires regular control and therefore is expensive.
Aus
Der Erfindung liegt daher die Aufgabe zugrunde, ein verbessertes Böschungsbauwerk anzugeben.The invention is therefore an object of the invention to provide an improved embankment structure.
Erfindungsgemäß wird die Aufgabe mit einem Böschungsbauwerk, welches die in Anspruch 1 angegebenen Merkmale aufweist, gelöst.According to the invention the object is achieved with a slope structure, which has the features specified in
Vorteilhafte Ausgestaltungen sind Gegenstand der abhängigen Ansprüche.Advantageous embodiments are the subject of the dependent claims.
Das erfindungsgemäße Böschungsbauwerk weist Lagen von Erdstoff mit jeweils luftseitigen Abschlusselementen auf, welche mit in den Erdstoff gerichteten Rückverankerungen kraftschlüssig verbunden sind. Erfindungsgemäß ist luftseitig vor den Abschlusselementen eine Sichtmauer angeordnet, wobei zumindest Teile dieser Sichtmauer mit Abschlusselementen verbunden sind. Dadurch wird die statische Konstruktion des gattungsgemäßen Böschungsbauwerks durch die vorgesetzte Sichtmauer zusätzlich statisch gesichert, so dass das Sicherheitsniveau des erfindungsgemäßen Böschungsbauwerks gegenüber herkömmlichen gattungsgemäßen Böschungsbauwerken erhöht wird. Besonders vorteilhaft ist das mit einer vorgesetzten Sichtmauer erzeugbare sehr ansprechende Erscheinungsbild, das dem Erscheinungsbild einer sehr aufwändigen Sichtmauer-Konstruktion entspricht, während die tatsächliche Konstruktion eine nach dem System bewehrter Erde sehr einfach hergestellte Konstruktion ist. Besonders vorteilhaft ist zudem, dass die vorgesetzte Sichtmauer repariert, entfernt und gestaltet werden kann, da es nicht Bestandteil der statischen Konstruktion des Böschungsbauwerks ist.The embankment structure according to the invention has layers of earth, each with air-side terminating elements, which are non-positively connected with return anchors directed into the earth. According to the invention, a sight wall is arranged on the air side in front of the end elements, at least parts of this sight wall being connected to end elements. As a result, the static construction of the generic embankment structure is additionally statically secured by the superior sight wall, so that the safety level of the embankment structure according to the invention over conventional generic embankment structures is increased. Particularly advantageous is the producible with a superior fair wall very attractive appearance, which corresponds to the appearance of a very elaborate fair-wall construction, while the actual construction is a system reinforced by the system earth very simple construction. It is also particularly advantageous that the superior sight wall can be repaired, removed and designed, since it is not part of the static design of the embankment structure.
Eine Ausgestaltung der Erfindung sieht vor, dass Abschlusselemente Bestandteil der Sichtmauer sind. Dadurch werden Aufwand und Kosten zur Errichtung der vorgesetzten Sichtmauer weiter reduziert.An embodiment of the invention provides that terminating elements are part of the sight wall. As a result, effort and costs for the erection of the superior sight wall are further reduced.
Erfindungsgemäß sind die Abschlusselemente abgewinkelte Bewehrungsmatten, die besonders kostengünstig und mit individuellen Querschnitten und Geometrien herstellbar sind. Besonders bevorzugt sind die insbesondere die sichtbaren Bewehrungsmatten verzinkt, so dass sie dauerhaft korrosionsbeständig sind.According to the invention, the end elements are angled reinforcing mats, which can be produced in a particularly cost-effective manner and with individual cross-sections and geometries. Particularly preferably, in particular, the visible reinforcement mats are galvanized, so that they are permanently resistant to corrosion.
Erfindungsgemäß ist vorgesehen, dass Abschlusselemente jeweils benachbart übereinander angeordneter Lagen von Erdstoff miteinander verbunden sind, wobei bevorzugt jeweils ein oberer Rand eines aufrechten Schenkels einer abgewinkelten Bewehrungsmatte außerhalb eines unteren Randes eines aufrechten Schenkels einer abgewinkelten Bewehrungsmatte einer nächst höheren Lage angeordnet ist. Eine abgewinkelte Bewehrungsmatte weist jeweils einen inneren, vorzugsweise im Wesentlichen horizontal zu verlegenden Schenkel und einen aufrechten äußeren Schenkel auf. Unter einem aufrechten äußeren Schenkel soll dabei nicht nur ein vertikaler Schenkel, sondern auch ein gegenüber dem inneren Schenkel abgewinkelter Schenkel verstanden werden. Dadurch wird es auf einfache Weise möglich, dass von einer Vielzahl äußerer Schenkel von als Abschlusselementen dienenden abgewinkelten Bewehrungsmatten zunächst eine erdseitige Gabionenbegrenzung, nämlich besonders bevorzugt ein geschlossenes ebenes Bewehrungsgeflecht, bilden, sodass anschließend nach Errichtung eines weiteren ebenen Bewehrungsgeflechts als luftseitige Gabionenbegrenzung eine Gabionen-Konstruktion als Verblendschale angeordnet werden kann. Eine derartige Verblendschale ist eine Sichtmauer im Sinne der Erfindung. Diese Gabionen-Konstruktion ist eine auch als Halb-Gabione bezeichnete Konstruktion, bei der nicht einzelne, jeweils üblicherweise als Gabionen bezeichnete geschlossene Käfige gestapelt oder in sonstiger Weise verwendet werden, sondern bei der zwischen zwei beabstandeten Gabionen-Begrenzungen Steine eingefüllt werden. Derartige Gabionen-Begrenzungen sind in der Regel Bewehrungsmatten, deren Maschenweite kleiner ist als die Durchmesser der einzufüllenden Steine, wobei eine luftseitige Bewehrungsmatte mit Hilfe von Abstandshaltern bevorzugt parallel zu einer rückseitigen Gabionenbegrenzung angeordnet wird bzw. ist. Am Fuß ist ein Gabionen-Bodengitter angeordnet; an seitlichen, vertikalen Rändern ist eine Seitenbegrenzung angeordnet, so dass eine Halb-Gabione gebildet wird, in welche geeignete Steine einfüllbar sind.According to the invention, terminating elements are each connected adjacent to one another by layers of earth, wherein preferably one upper edge of an upright leg of an angled reinforcing mat is arranged outside a lower edge of an upright leg of an angled reinforcing mat of a next higher layer. An angled reinforcing mat has in each case an inner, preferably substantially horizontally to be laid leg and an upright outer leg. Under an upright outer leg is to be understood not only a vertical leg, but also an opposite the inner leg angled leg. This makes it possible in a simple manner that of a plurality of outer legs serving as closing elements angled reinforcement mats first an earth gabion boundary, namely particularly preferably a closed planar reinforcement mesh, form, so then after the establishment of another planar reinforcing mesh as the air side gabion a gabion construction can be arranged as a veneer. Such a veneer is a sight wall in the context of the invention. This gabion construction is a construction also referred to as semi-gabion, in which non-individual closed cages, each commonly referred to as gabions, are stacked or otherwise used, but stones are filled in between the two spaced gabion boundaries. Such gabion boundaries are usually reinforcing mats whose mesh size is smaller than the diameter of the stones to be filled, wherein an air-side reinforcing mat is preferably arranged by means of spacers parallel to a rear gabion boundary or is. At the foot of a gabion floor grid is arranged; at lateral, vertical edges a side boundary is arranged, so that a semi-gabion is formed, in which suitable stones are fillable.
Eine andere Ausgestaltung der Erfindung sieht vor, dass das Abschlusselement jeder Lage eine Rückverankerung aufweist, wodurch ein besonders sicheres und/oder besonders steiles Böschungsbauwerk errichtet werden kann.Another embodiment of the invention provides that the end element of each layer has a back anchoring, whereby a particularly safe and / or very steep embankment structure can be built.
Bevorzugt sind die Lagen von Erdstoff und damit die dazwischen verlaufenden Rückverankerungen im Wesentlichen horizontal angeordnet. Die Verbindung zwischen Rückverankerung und korrespondierendem Abschlusselement erfolgt dadurch, dass der innere Schenkel von als Abschlusselementen dienenden abgewinkelten Bewehrungsmatten auf einen luftseitigen Rand eines als Rückverankerung dienenden Geokunststoffs aufgelegt wird, so dass infolge der Auflast einer oder mehrerer über dem so gebildeten Überlappungsbereich angeordneter Schichten von Erdstoff eine kraftschlüssige Verbindung geschaffen wird. Die Verwendung von Geokunststoffen als Rückverankerungen ist eine besonders effiziente und kostengünstige Ausgestaltung der Erfindung, da Geokunststoffe besonders einfach zu verlegen sind.Preferably, the layers of soil and thus the rear anchorages extending therebetween are arranged substantially horizontally. The connection between the back anchoring and the corresponding terminating element is effected by placing the inner leg of angled reinforcing mats serving as terminating elements on an air-side edge of a geosynthetic material which serves as a back anchoring, so that a layer of earth material is disposed as a result of the loading of one or more layers of earth material arranged over the thus formed overlapping region frictional connection is created. The use of geosynthetics as back anchors is a particularly efficient and inexpensive embodiment of the invention, since geosynthetics are particularly easy to install.
Erfindungsgemäß ist vorgesehen, dass als Sichtmauer eine Gabionenwand angeordnet ist. Das optische Erscheinungsbild eines derart ausgestalteten Böschungsbauwerks ist besonders ansprechend; ein derartiges Böschungsbauwerk liefert den Eindruck besonders hoher Wertigkeit, da üblicherweise mittels Gabionen errichtete Böschungsbauwerke als Schwergewichtsmauern hergestellt werden, wozu gemäß Stand der Technik besonders große, das heißt besonders tiefe Gabionen erforderlich wären. Dabei bilden aufrechte Schenkel von als Abschlusselementen dienenden abgewinkelten Bewehrungsmatten eine erdseitige Gabionenbegrenzung.According to the invention, it is provided that a gabion wall is arranged as the sight wall. The visual appearance of a thus designed embankment structure is particularly appealing; Such a slope structure gives the impression of particularly high quality, since usually built by means of gabions embankment structures are manufactured as heavyweight walls, which according to the prior art particularly large, that is particularly deep gabions would be required. In this case, upright legs of angled reinforcing mats serving as end elements form an earth-bound gabion boundary.
Die Erfindung sieht vor, dass ein mit den äußeren Schenkeln verbundenes luftseitiges Drahtgitter, insbesondere eine Bewehrungsmatte, eine luftseitige Gabionenbegrenzung bildet. Besonders bevorzugt ist dieses luftseitige Drahtgitter verzinkt, so dass die als Sichtwand vorgesetzte Gabionen-Konstruktion korrosionsbeständig und damit besonders dauerhaft ist.The invention provides that an air-side wire grid, in particular a reinforcement mat, connected to the outer legs forms an air-side gabion boundary. This air-side wire grid is particularly preferably galvanized, so that the gabion construction, which is in the form of a visible wall, is corrosion-resistant and therefore particularly durable.
Eine weitere Ausgestaltung der Erfindung sieht vor, dass am Böschungsfuß eine Sauberkeitsschicht unterhalb der Sichtmauer angeordnet ist, wodurch diese besonders einfach herstellbar und besonders einfach auszurichten ist. Bevorzugt ist unterhalb der Sauberkeitsschicht ein Austauschboden angeordnet.A further embodiment of the invention provides that at the slope foot a cleanliness layer is arranged below the sight wall, whereby this is particularly easy to manufacture and very easy to align. Preferably, a replacement tray is arranged below the cleanliness layer.
Eine weitere Ausgestaltung der Erfindung sieht vor, dass auf der Böschungskrone ein Wind- oder Schallschutzzaun angeordnet ist. Dadurch kann der bautechnische Aufwand gegenüber einem üblichen Böschungsbauwerk mit gleicher Schalldämpfung deutlich reduziert werden.A further embodiment of the invention provides that a wind or noise protection fence is arranged on the embankment crown. As a result, the structural complexity compared to a conventional embankment structure with the same sound attenuation can be significantly reduced.

Vor der nach dem System bewehrter Erde errichteten Böschung ist eine Gabionenwand als Sichtmauer angeordnet, so dass das Böschungsbauwerk 1 ein sehr ansprechendes Erscheinungsbild aufweist, das nämlich dem Erscheinungsbild einer sehr aufwändigen Gabionen-Konstruktion entspricht, wobei die tatsächliche Konstruktion eine nach dem System bewehrter Erde aber eine sehr einfach und damit kostengünstiger hergestellte Konstruktion ist, als eine reine Gabionen-Konstruktion mit gleichem Erscheinungsbild.In front of the system-reinforced soil, there is a gabion wall as a sight wall, so that the
Dadurch, dass die als vorgesetzte Gabionen-Konstruktion errichtete Sichtmauer mit Abschlusselementen 3 verbunden sind, können die genannten Vorteile erreicht werden, indem die Sichtmauer sehr schlank ausgeführt werden kann. Die Dicke der Sichtmauer beträgt etwa 20 cm, wodurch das erfindungsgemäße Böschungsbauwerk 1 vergleichsweise kostengünstig ausführbar ist: Die Dicke einer Gabionenwand einer herkömmlichen Gabionen-Konstruktion mit gleichem Erscheinungsbild, also wobei die Sichtmauer aus Gabionen als Schwergewichtsmauer gefertigt wäre, würde demgegenüber deutlich mehr als einen Meter betragen und wäre sehr viel aufwändiger zu errichten.The fact that the built as a superior gabion construction sight wall are connected to end

Zur Aussteifung der abgewinkelten Bewehrungsmatten sind Distanzhalter 3.3 angeordnet, deren Enden jeweils mit einem äußeren Schenkel 3.1 und einem inneren Schenkel 3.2 der abgewinkelten Bewehrungsmatte verbunden sind, so dass beim Einbringen und insbesondere beim Verdichten der Lage 2 von Erdstoff ein Aufbiegen der abgewinkelten Bewehrungsmatte verhindert wird.For stiffening the angled reinforcing mats spacers 3.3 are arranged, whose ends are each connected to an outer leg 3.1 and an inner leg 3.2 of the bent reinforcing mat, so that upon insertion and in particular during the compression of the
Die Abschlusselemente 3 jeweils übereinander angeordneter Lagen 2 von Erdstoff sind miteinander verbunden, indem jeweils ein oberer Rand eines aufrechten Schenkels 3.1 einer abgewinkelten Bewehrungsmatte außerhalb unmittelbar neben einem unteren Randes eines aufrechten Schenkels 3.1 einer abgewinkelten Bewehrungsmatte der nächst höheren Lage 2 angeordnet ist. Die so gebildeten Überlappungsbereiche sind auf hier nicht gezeigte Weise mittels Rödeldraht miteinander verbunden. Dadurch wird von einer Vielzahl äußerer Schenkel 3.1 ein ebenes, geschlossenes Bewehrungsgeflecht als erdseitige Gabionenbegrenzung gebildet, zu welchem das Drahtgeflecht 5 in einem Abstand von ca. 20 cm parallel verlaufend angeordnet ist.The
Das luftseitige Drahtgitter 5 ist mittels einer Vielzahl von Abstandshaltern 6 an den äußeren Schenkeln 3.1 befestigt. Der Abstand der Abstandshalter 6 untereinander ist unter Berücksichtigung der Dimensionierung des luftseitigen Drahtgitters 5 so gewählt, dass dieses beim Einfüllen von Steinen 7 nicht in erkennbarer Weise ausbeult.The air-
Innerhalb der äußeren Schenkel 3.1 ist über dessen gesamte Höhe ein Vlies 11 angeordnet, welches verhindert, dass Feinanteile aus den Lagen 2 von Erdstoff ausgewaschen werden. Dazu ist jedes Vlies 11 jeweils auch oberhalb eines jeden inneren Schenkels 3.2 der abgewinkelten Bewehrungsmatte aufgelegt.Within the outer leg 3.1, a
Die hier gezeigte Variante erlaubt zudem die Ausbildung von hier nicht dargestellten horizontalen Versätzen; und zwar sowohl betreffend die aufrechten Schenkel 3.1 als auch betreffend das luftseitige Drahtgitter 5. Dadurch ist es möglich, eine Sichtmauer als Gabionenwand zu errichten, bei der der Anschein erweckt wird, es stünden horizontalebenenweise versetzte Gabionen übereinander. Ein derart ausgebildetes Böschungsbauwerk 1 kann den Eindruck einer als Schwergewichtswand ausgebildeten Gabionenwand erwecken, bei der sehr große Gabionen versetzt über einander gestapelt sind.The variant shown here also allows the formation of horizontal offsets, not shown here; This makes it possible to construct a sight wall as a gabion wall, which gives the appearance that there are horizontal plane-wise offset gabions one above the other.
