Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zur Herstellung einer Erdböschung, die sich aus mehreren verdichteten Füllbodenlagen und einer bewehrten Außenhaut zusammensetzt, bei dem schichtweise ein tragender und verfestigter Bereich aufgebaut wird, der sich zusammensetzt aus mehreren Lagen Füllboden, der je Lage von einem im wesentlichen horizontalen Abschnitt, einem vertikalen Abschnitt und einem zurückgefalteten Abschnitt der flexiblen Bewehrungsmatte umschlossen und verdichtet wird.The invention relates to a method for producing a Erdböschung, which is composed of a plurality of compacted Füllbodenlagen and a reinforced outer skin, in which a load-bearing and consolidated area is built up in layers, which is composed of several layers of filling soil, the layer of each of a substantially horizontal section, a vertical section and a folded-back section of the flexible reinforcement mat is enclosed and compacted.
Ein Verfahren und eine Erdböschung dieser Art sind bekannt aus der EP-A-0 603 460. Bei diesem bekannten Verfahren ist jeder von einer Bewehrungsmatte umschlossenen Füllbodenlage ein aus einer Stahlgittermatte geformtes Rahmengestell zugeordnet, das einen unteren, horizontalen Boden und eine geneigte Frontwand aufweist. Die Frontwand ist mit einem Winkel vom horizontalen Boden abgewinkelt, die dem Böschungswinkel entspricht. Bei der Errichtung der Erdböschung wird zuerst das Rahmengestell je Füllbodenlage so angeordnet und ausgerichtet, daß die von einer Bewehrungsmatte umschlossene Füllbodenlage sich auf den rückwärtigen Bereich des Bodens des Rahmengestells auflegt und die abgewinkelte Frontwand von der Füllbodenlage einen Abstand einhält, so daß zwischen der Frontwand und der Stirnwand der Füllbodenlage ein Raum entsteht, in den je Lage Vegetationsboden eingefüllt werden kann.A method and earth embankment of this type are known from EP-A-0 603 460. In this known method, each filler base enclosed by a reinforcing mat is associated with a frame formed of a steel mesh mat having a lower horizontal bottom and a sloping front wall. The front wall is angled away from the horizontal floor, which corresponds to the slope angle. In the construction of Erdböschung the frame is first arranged per Füllbodenlage and aligned so that the enclosed by a reinforcing mat Füllbodenlage hangs on the rear portion of the bottom of the frame and the angled front wall of the Füllbodenlage maintains a distance, so that between the front wall and the front wall of the Füllbodenlage creates a space in which each layer of vegetation can be filled.
Bei diesem bekannten Verfahren ist es schwierig, die Rahmengestelle so auszurichten, daß ihre Frontwände eine kontinuierliche stufenlose Fläche bilden.In this known method, it is difficult to align the frame racks so that their front walls form a continuous stepless surface.
Aus der WO 96 33314 A ist ein Verfahren zur Herstellung einer Erdböschung bekannt, bei dem die Erdböschung sich aus mehreren Bodenlagen zusammensetzt, die im Bereich ihrer Stirnwände von Matten umschlossen sind. Zur Bildung einer begrünbaren Außenhaut der Böschung ist jeder Bodenlage eine Gittermatte zugeordnet, die gelenkig mit der Gittermatte der jeweils benachbarten Bodenlage verbunden ist. Während des Aufbaus der Erdböschung werden die Gittermatten der einzelnen Bodenlagen gemeinsam von Führungsstangen in einem Winkel gehalten, der dem Böschungswinkel des fertiggestellten Erddammes entspricht. Nach Fertigstellung des Erddammes können die von Zugseilen in einem bestimmten Winkel gehaltenen Führungsstangen zur weiteren Verwendung entnommen werden. Um eine Begrünung der Außenhaut zu ermöglichen, können bei diesem Verfahren die Bodenlagen nicht hoch verdichtet werden. Das Einfüllen eines unverdichteten, lockeren Vegetationsbodens ist hier nicht möglich.From WO 96 33314 A a method for producing a Erdböschung is known in which the Erdböschung is composed of several floor layers, which are enclosed in the region of their end walls of mats. To form a plantable outer skin of the embankment, each floor layer is one Assigned grid mat, which is hingedly connected to the grid mat of the respective adjacent base layer. During the construction of the earth embankment, the grid mats of the individual ground layers are held together by guide rods at an angle which corresponds to the angle of repose of the completed earth embankment. After completion of the Erddammes held by traction cables at a certain angle guide rods can be removed for further use. In order to allow a greening of the outer skin, with this method, the bottom layers can not be highly compressed. The filling of an uncompacted, loose vegetation soil is not possible here.
Auch die EP-A-0 872 597 befaßt sich mit der Herstellung einer bewehrten Erdböschung mit einer begrünbaren Außenhaut. Bei diesem Verfahren werden verdichtete Füllbodenlagen erstellt, deren Stirnbereiche von geotextilen Bewehrungsmatten umschlossen sind. Die Stirnfläche der übereinander angeordneten Füllbodenlagen sind im wesentlichen entsprechend dem Böschungswinkel geneigt. Im Abstand vor diesen verfestigten Füllstofflagen werden zur Bildung der begrünbaren Außenhaut Gittermatten angeordnet, deren Höhe der Höhe einer Füllbodenlage entspricht. Diese Gittermatten werden entsprechend dem Böschungswinkel von Zugkräfte aufnehmenden Verbindungselementen oder Abstandhaltern gehalten, die zwischen den verfestigten Füllbodenlagen verankert sind. Diese Verbindungselemente oder Abstandhalter sind aus einem 14 mm Stahlrundstab V-förmig gebogen, und die freien Enden der beiden Arme sind in vertikalen Ebenen hakenförmig umgebogen, so daß diese hakenförmigen Enden um horizontale Stäbe der Gittermatten gehakt werden können. Dabei wird die unterste Gittermatte mit der unteren Kante schwenkbar am Boden befestigt, und jede höhere Gittermatte wird mit der unteren Kante auf der oberen Kante der jeweils darunter befindlichen Gittermatte befestigt. In den Raum zwischen der Stirnfläche der ersten und jeder höheren Füllstofflage und der ersten und jeder höheren Gittermatte wird von Lage zu Lage Vegetationsboden eingefüllt. Weil die Außenhaut sich aus mehreren, einzeln einstellbaren Gittermatten zusammensetzt und die Gittermatten je Lage mit Vegetationsboden hinterfüllt werden müssen, ist es schwer, eine kontinuierliche, stufenlose und buckelfreie Außenhaut zu erzielen.Also, EP-A-0 872 597 is concerned with the manufacture of a reinforced earth embankment having a greener outer skin. In this process, densified Füllbodenlagen be created whose forehead areas are surrounded by geotextile reinforcement mats. The end face of the superimposed Füllbodenlagen are inclined substantially corresponding to the slope angle. At a distance from these solidified Füllstofflagen grid mats are arranged to form the greenable outer skin whose height corresponds to the height of a Füllbodenlage. These grid mats are held according to the angle of repose of tensile forces receiving fasteners or spacers that are anchored between the solidified Füllbodenlagen. These fasteners or spacers are bent in a V-shape from a 14 mm steel round bar, and the free ends of the two arms are bent hook-shaped in vertical planes, so that these hook-shaped ends can be hooked around horizontal bars of the grid mats. In this case, the lowermost grid mat is pivotally attached to the bottom with the lower edge, and each higher grid mat is fastened with the lower edge on the upper edge of the respectively underlying grid mat. In the space between the end face of the first and each higher Füllstofflage and the first and each higher grid mat is filled from layer to layer vegetation soil. Because the outer skin consists of several, individually adjustable grid mats and the grid mats have to be backfilled with vegetation soil per location, it is difficult to achieve a continuous, stepless and hump-free outer skin.
Es ist also bekannt, Erdböschungen und Stützwände mit einer Neigung von 45° bis 90° zur Horizontalen mehrschichtig auszubilden, wobei jede etwa 50 cm bis 80 cm dicke Schicht aus Füllboden gebildet ist, der zumindest teilweise von einer flexiblen geotextilen Bewehrungsmatte, insbesondere Geogittermatte, umschlossen ist. Die flexible Bewehrungsmatte hat dabei einen unteren, im wesentlichen horizontalen Abschnitt, auf dem der Füllboden aufliegt, an der Außenseite einen Abschnitt, der sich über die Höhe der jeweiligen Füllbodenschicht erstreckt, und einen zurückgefalteten Abschnitt, auf dem der untere Abschnitt der Bewehrungsmatte der nächst höheren Füllbodenschicht aufliegt. Die einzelnen Füllbodenschichten werden mittels Rüttler oder Vibrationswalzen verdichtet, bevor die nächst höhere Füllbodenschicht aufgebracht wird. Um eine gute Verzahnung der Füllbodenschichten zu erreichen, sind die flexiblen Bewehrungsmatten aus hochmodulen Polyestergarnen hergestellte Geogitter mit einer Maschenweite von 10 x 10 mm bis 50 x 50 mm. Die Polyestergarne bzw. das Geogitter ist mit einer Polymer-Schutzschicht ausgerüstet. Ist die Böschungswand im wesentlichen senkrecht, dann stehen die vertikalen Abschnitte der Bewehrungsmatten der einzelnen Füllbodenschichten im wesentlichen in einer vertikalen Ebene übereinander. Ist die Böschungswand um 45° geneigt, dann sind die vertikalen Abschnitte der Füllbodenschichten zur nächstfolgenden Füllbodenschicht um die Höhe der vertikalen Abschnitte der Bewehrungsmatten bzw. um die Dicke der Füllbodenschicht versetzt. Die Maschenweite der Bewehrungsmatte wird in Abhängigkeit von der Korngröße des Füllbodens gewählt und sollte etwa so groß sein wie die Korngröße von 50% des Füllbodens.It is therefore known to form Erdböschungen and retaining walls with an inclination of 45 ° to 90 ° to the horizontal multi-layer, each about 50 cm to 80 cm thick layer is formed of filling floor, at least partially enclosed by a flexible geotextile reinforcement mat, especially geogrid mat is. The flexible reinforcing mat has a lower, substantially horizontal portion on which the filling floor rests, on the outside a portion which extends over the height of the respective filling bottom layer, and a folded-back portion, on which the lower portion of the reinforcing mat of the next higher Füllbodenschicht rests. The individual Füllbodenschichten be compacted by vibrators or vibrating rollers before the next higher Füllbodenschicht is applied. In order to achieve a good toothing of the filling soil layers, the flexible reinforcing mats are geogrids made of high-modulus polyester yarns with a mesh width of 10 × 10 mm to 50 × 50 mm. The polyester yarns or the geogrid is equipped with a polymer protective layer. If the slope wall is substantially vertical, then the vertical sections of the reinforcing mats of the individual Füllbodenschichten are substantially one above the other in a vertical plane. If the slope wall is inclined by 45 °, then the vertical sections of the Füllbodenschichten the next Füllbodenschicht are offset by the height of the vertical sections of the reinforcing mats or by the thickness of the Füllbodenschicht. The mesh size of the reinforcement mat is chosen as a function of the grain size of the filling soil and should be about as large as the grain size of 50% of the filling soil.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Herstellung einer Erdböschung zu entwickeln, bei welchem der Füllboden zuverlässig verdichtet werden kann, wobei die Frontseite der Bewehrungsmatte des Füllbodens trotz der Verdichtung einen definierten, möglichst vertikalen Verlauf hat und bei dem unabhängig von den verdichteten Füllbodenlagen Vegetationsboden, Muttererde oder dgl. in einen von unten bis oben durchgehenden freien Raum hinter einer kontinuierlich und stufenlos verlaufenden Außenhaut eingebracht werden kann.The invention has for its object to develop a method for producing a Erdböschung in which the filling floor can be reliably compressed, the front side of the reinforcement mat of the Füllboden despite the compaction has a defined, as vertical as possible course and in which regardless of the compacted Füllbodenlagen Vegetation soil, mother earth or the like. In a continuous from bottom to top free space behind a continuously and continuously extending outer skin can be introduced.

Eine weitere Aufgabe der Erfindung ist es, eine Erdböschung zu schaffen, bei der nach Erstellung des tragenden und verfestigten Bereiches die im Abstand von diesem Bereich aufzustellende Wand aus Gittermatten schnell und zuverlässig so befestigt werden kann, daß die Gittermatten eine kontinuierliche, stufenlose Fläche bilden.A further object of the invention is to provide a Erdböschung, in which after creation of the supporting and solidified area to be established at a distance from this area wall of grid mats can be quickly and reliably fixed so that the grid mats form a continuous, continuous surface.

In der folgenden Beschreibung wird das erfindungsgemäße Verfahren sowie die mit diesem Verfahren hergestellte Erdböschung unter Bezugnahme auf die Zeichnungen von drei Ausführungsbeispielen näher erläutert. Die Zeichnungen zeigen in:
- Fig. 1 einen Querschnitt durch eine erfindungsgemäß hergestellte Böschung,

- FIG. 2 shows a cross section through a noise protection wall that can be planted on both sides, FIG.
- Fig. 3 shows a cross section through a one-sided plantable sound barrier.
Die Fig. 1 zeigt den Querschnitt einer Erdböschung, die sich zusammensetzt aus einer natürlichen, vorhandenen Erdböschung 3, vor der schichtweise ein geotextilbewehrter, tragender und verfestigter Bereich aufgebaut wurde und vor der sich ein nicht tragender Außenhautbereich 2 befindet.Fig. 1 shows the cross section of a Erdböschung, which is composed of a natural, existing
Der tragende und verfestigte Bereich 1 setzt sich in diesem Beispiel zusammen aus fünf Lagen 21 - 25 Füllboden 4, der je Lage an drei Seiten von einer flexiblen Bewehrungsmatte 5 umschlossen ist. Die flexible Bewehrungsmatte 5 jeder Füllbodenlage 21 - 25 hat einen im wesentlichen horizontalen unteren Abschnitt 15, einen vorderen vertikalen Abschnitt 16 und einen zurückgefalteten oberen Abschnitt 17. Jede Füllbodenlage 21 - 25 wird mittels Vibrationswalzen oder dergleichen hochverdichtet, bevor die nächstfolgende höhere Lage aufgebaut wird. Zur Erzielung eines möglichst vertikalen Abschnitts 16 der die Füllbodenlagen 21 - 25 umschließenden flexiblen Bewehrungsmatten 5 wird vor dem Einfüllen des Bodens 4 je Lage eine abnehmbare vertikale Schalung, z.B. aus chalbrettern, angebracht. Hat der einzufüllende Boden 4 seine Schichtdicke erreicht, wird der Abschnitt 15 der Bewehrungsmatte zurückgeklappt und der eingefüllte Boden hochverdichtet. Die flexible Bewehrungsmatte sowie die Schalung der nächst folgenden Lage werden so angebracht, daß die Böschung die jeweils gewünschte Neigung erhält. Es entstehen dadurch Stufen 14, die um so größer sind, je kleiner der Böschungswinkel gegenüber der Horizontalen ist. Während des Aufbaus des tragenden und verfestigten Bereiches können zwischen den Füllbodenlagen 21 - 25 stabförmige Abstandhalter 8 angebracht werden, die über die vertikalen Bereiche der flexiblen Bewehrungsmatten 5 um vorzugsweise 10 bis 15 cm vorragen, so daß an ihnen im Abstand 36 von mindestens 10 cm eine von unten nach oben durchgehende steife und großflächige Gittermatte 7 befestigt werden kann. Sofern die Gittermatte 7 relativ große Gitteröffnungen aufweist, dann ist an der Innenseite dieser Gittermatte 7 eine mit kleinen Maschen oder Öffnungen versehene Lage 9 aus Gittergewebe, Maschendraht oder Vlies anzubringen, damit der zwischen dem tragenden und verfestigten Bereich 1 und der steifen Gittermatte 7 einzufüllende Vegetationsboden 10 nicht durch die Öffnungen in der Gittermatte hindurchfällt.The load-bearing and solidified
Die Abstandhalter 8 können aber auch nach Erstellen des tragenden und verfestigten Bereiches 1 horizontal oder aber auch rechtwinklig zur Böschungsneigung in den tragenden und verfestigten Bereich eingetrieben werden. Die Abstandhalter 8 können mit Widerhaken 13 versehen sein. An ihren vorragenden Enden können die Abstandhalter 8 Anschläge 11 für die steife Gittermatte aufweisen. Diese Anschläge können entlang den stabförmigen Abstandhaltern 8 einstellbar sein. Zweckmäßigerweise sind die vorragenden Enden der stabförmigen Abstandhalter 8 mit einem Schraubgewinde zur Aufnahme und Führung einer Spannmutter 12 versehen, so daß die steife Gittermatte genau ausgerichtet werden kann, ggf. auch noch nach Einfüllen des Vegetationsbodens 10.However, the
Vorteilhafterweise wird der Vegetationsboden 10 bzw. ein Gemisch aus Mutterboden, Substrat und ggf. auch Samen mit Wasserzugaben in einen pumpfähigen Zustand gebracht und in den Raum zwischen dem tragenden und verfestigten Bereich 1 und der Außenhaut eingepumpt. In diesem Fall erfolgt das Abtropfen des überschüssigen Pumpwassers filterstabil durch die vorwiegend geotextile Matte 9.Advantageously, the
Die Gittermatte, die eine Baustahlgewebematte sein kann und durch Verzinken oder durch eine Kunststoffbeschichtung korrosionsbeständig sein kann, schützt ebenso wie die mindestens 10 cm dicke Schicht aus Vegetationsboden die flexible textile Bewehrungsmatte der Füllstofflagen 21 - 25.The lattice mat, which may be a Baustahlgewebematte and may be corrosion resistant by galvanizing or by a plastic coating, as well as the at least 10 cm thick layer of vegetation soil, the flexible textile reinforcement mat of the filler layers 21 - 25.
