Description

Die Erfindung betrifft ein Verfahren zum Einbringen einer wasserundurchlässigen Schicht ins Erdreich, insbesondere unterhalb einer Mülldeponie, bei welchem zuerst parallel zueinander verlaufende und der Drainage dienende Tunnel ins Erdreich eingebracht werden sowie eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for introducing a water-impermeable layer into the ground, in particular below a landfill, in which tunnels which run parallel to one another and serve for drainage are first introduced into the ground, and a device for carrying out the method.

Bei älteren Mülldeponien, welche Sondermüll enthalten, besteht die Gefahr der Verunreinigung des Grundwassers insbesondere durch schwer abbaubare Halogenkohlen­wasserstoffe. Wo ein Umsetzen der Mülldeponie nicht möglich ist, ist es erforderlich, unterhalb der Deponie eine wasserundurchlässige Schicht ins Erdreich zusammen mit Drainagerohren einzubringen. Ein Vorschlag besteht darin, über einen Anfahrschacht Vorpresstunnel ins Erdreich einzubringen, von denen Stichrohre abgehen, über welche Injektionslanzen ins Erdreich eingebracht werden, um Chemikalienlösungen einzubringen, die das Erdreich verfestigen und abdichten. Dies hat den Nach­teil, daß die Abdichtung eine relativ geringe Druckfestig­keit aufweist, schon bei geringen Bodenverschiebungen die Abdichtung nicht mehr gewährleistet ist, und die Rohre relativ eng nebeneinander verlegt sein müssen, da die Injektionsbereiche ineinander übergehen bzw. einander überlappen sollen. Eine solche Vorgehensweise ist nicht nur sehr teuer sondern auch aus den vorgenannten Gründen bezüglich ihrer Erfolgsaussichten sehr zweifel­haft.In older landfills that contain hazardous waste, there is a risk of groundwater contamination, particularly due to halogen hydrocarbons that are difficult to degrade. Where it is not possible to relocate the landfill, it is necessary to install a waterproof layer below the landfill together with drainage pipes. One proposal is to introduce a pre-press tunnel into the ground via a start-up shaft, from which branch pipes branch off, via which injection lances are introduced into the ground, in order to introduce chemical solutions that do this Solidify and seal the soil. This has the disadvantage that the seal has a relatively low compressive strength, the seal is no longer guaranteed even with slight ground displacements, and the pipes have to be laid relatively close to one another, since the injection areas should merge or overlap. Such a procedure is not only very expensive but also very doubtful for the reasons mentioned above with regard to its chances of success.

Es wurden schon Überlegungen angestellt, Mülldeponien zu untertunneln und zwichen den Tunnel wasserundurch­lässige Schichten , beispielsweise aus Ton und/oder aus Kunststoffolie einzubringen.Considerations have already been made to tunnel garbage dumps and to insert water-impermeable layers between the tunnel, for example made of clay and / or plastic film.

Hierbei stellt sich die Aufgabe, Verfahren und Vorrich­tung so zu gestalten, daß es mit vernünftigem finan­ziellen und technischem Aufwand durchgeführt werden kann.The task here is to design the method and device so that it can be carried out with reasonable financial and technical effort.

Gelöst wird diese Aufgabe mit den kennzeichnenden Merkmalen der Ansprüche 1 und 5.This object is achieved with the characterizing features of claims 1 and 5.

Ausgehend von einem Anfahrschacht 1 werden in das Erdreich 2 unterhalb einer Mülldeponie 3 zueinander parallel verlaufende Vorpresstunnel 4 eingebracht, die bis zu einem Endschacht 5 verlaufen. Zwischen benachbarten Tunnel 4 wird jeweils eine sie verbin­dende wasserundurchlässige Schicht 6 eingebracht. Jede wasserundurchlässige Schicht 6 ist nach oben bogenförmig ausgebildet, so daß das Wasser jeweils in Richtung der Tunnel 4 fließt,die der Drainage dienen.Starting from a start-up shaft 1, pre-press tunnels 4 running parallel to one another are introduced into the ground 2 below a landfill 3, which run as far as an end shaft 5. A water-impermeable layer 6 connecting them is introduced between adjacent tunnels 4. Each water-impermeable layer 6 is arched upwards, so that the water flows in the direction of the tunnels 4, which serve for drainage.

Der Abstand zwischen benachbarten Tunnel 4 kann beispielsweise 10 bis 30m betragen.The distance between adjacent tunnels 4 can be, for example, 10 to 30 m.

Gemäß Fig. 4 sind die wasserundurchlässigen Schichten 6 oberseitig mit einem Tunnel 4 verbunden. An der Oberseite jedes Tunnels sind Drainageöffnungen 7 vorgesehen. Weiterhin sind seitlich am Tunnel 4 Zahn­stangen 8 angeordnet, in welche motorische Antriebe eines Vortriebsschilds eingreifen, wie nachfolgend noch erläutert wird.4, the water-impermeable layers 6 are connected on the upper side to a tunnel 4. Drainage openings 7 are provided at the top of each tunnel. Furthermore, 4 toothed racks 8 are arranged on the side of the tunnel, in which motor drives of a driving shield engage, as will be explained below.

Bei der Ausführungsform nach Fig. 5 sind die wasserun­durchlässigen Schichten 6 seitlich mit dem Tunnel 4 verbunden. Oberhalb dieser Verbindungslinie befin­den sich die Drainageöffnungen 7. Unterhalb diesen Verbindungslinien verlaufen die Zahnstangen 8. Das Vortriebsgerät besteht aus einem Vortriebsschild 9, dessen Spannweite dem Abstand zweier benachbarter Tunnel 4 entspricht. Es hat eine Länge von bei­spielsweise 1,5 bis 2,5m und eine Höhe von beispiels­weise 0,2 bis 0,3m. Es ist nach oben bogenförmig ausgebildet. Gemäß Fig. 7 kann seine Spitze 10 um eine horizontalverlaufende Achse 11 schwenkbar sein. Diese Spitze kann mit einem Spül- und/oder Rüttel­kopf, einer Fräse, Säge oder Reißwelle versehen sein. Hinter seiner Spitze ist der Schild doppelwandig ausgebildet, wobei die beiden Wände 12, 13 durch Träger 14 miteinander versteift sind. An seiner Rück­seite ist der Schild offen, wobei die obere Wand 12 über die untere Wand 13 hinaus verlängert sein kann. In das hintere offene Ende 15 wird die wasser­undurchlässige Schicht eingebracht. Bei dieser Schicht kann es sich beispielsweise um Armier- oder Faserbeton, Makadam oder Ton handeln.In the embodiment according to FIG. 5, the water-impermeable layers 6 are connected laterally to the tunnel 4. The drainage openings 7 are located above this connecting line. The racks 8 run below these connecting lines. The tunneling device consists of a tunneling shield 9, the span of which corresponds to the distance between two adjacent tunnels 4. It has a length of, for example, 1.5 to 2.5 m and a height of, for example, 0.2 to 0.3 m. It is arched upwards. 7, its tip 10 can be pivotable about a horizontal axis 11. This tip can be provided with a rinsing and / or vibrating head, a milling machine, saw or tearing shaft. Behind its tip, the shield is double-walled, the two walls 12, 13 being stiffened to one another by supports 14. The back of the shield is open, and the upper wall 12 can be extended beyond the lower wall 13. The water-impermeable layer is introduced into the rear open end 15. This layer can be, for example, reinforcing or fiber concrete, macadam or clay.

Nachdem die Vorpresstunnel 4 eingebracht sind, wird zwischen zwei benachbarten Tunnel 4 der Vortriebsschild 9 angesetzt, dessen nicht dargetellte motorische Antriebe, die seitlich am Schild vorgesehen sind, in die Zahnstangen 8 dieser Tunnel 4 eingreifen. Nach Inbetriebnahme dieser motorischen Antriebe drückt sich der Schild 9 durch das Erdreich, daß hierdurch verdichtet wird. Gleichzeitig wird über das hintere Ende 15 des Vortriebsschildes 9 das Material für die wasserundurchlässige Schicht 6 eingebracht, wobei das Einbringen bevorzugt unter Druck erfolgt. Das Einbringen unter Druck begünstigt die durch die motori­schen Antriebe bewirkte Vorschubbewegung des Schildes.After the pre-press tunnels 4 have been introduced, the tunneling shield 9 is placed between two adjacent tunnels 4, the motor drives (not shown), which are provided on the side of the shield, engage in the toothed racks 8 of this tunnel 4. After commissioning of these motor drives, the shield 9 presses through the soil, which compresses it. At the same time, the material for the waterproof layer 6 is introduced via the rear end 15 of the tunneling shield 9, the introduction preferably taking place under pressure. The Application under pressure favors the forward movement of the shield caused by the motor drives.

Auf diese Wiese wird jeweils zwischen zwei benachbarten Tunnel eine wasserundurchlässige Schicht eingebracht.In this meadow, a water-impermeable layer is placed between two neighboring tunnels.

Die Zahnstangen 8 sind so ausgebildet, daß ihre Basis gleichzeitig als längsverlaufende Führungen für den Schild 9 dienen.The racks 8 are designed so that their base serve simultaneously as longitudinal guides for the shield 9.

Die Energie- und Speiseleitungen für den Schild 9 verlaufen jeweils in einem Tunnel 4. Im Bereich der Zahnstangen 8 sind Schlitze vorgesehen, durch welche die Energie- und Speiseleitungen vom Tunnelinneren zum Schild 9 verlaufen. Die Energie- und Speiseleitungen werden bei Erreichen eines Schiltzendes am Schild 9 umgesteckt auf einen Anschluß, der sich in Höhe des Anfangs des nächsten Schlitzes befindet. Auf diese Weise wird ein taktweiser Vortrieb des Vortriebs­schildes erreicht. Es ist auch mögilch, die Energiezu­fuhr wechselweise über die benachbarten beiden Tunnel durchzuführen. In diesem Fall überlappen sich bevor­zugt die Schlitze einander benachbarter Tunnel 4. Hiermit ist auch ein kontinuierlicher Vortrieb des Schildes möglich.The energy and feed lines for the shield 9 each run in a tunnel 4. In the area of the toothed racks 8, slots are provided through which the energy and feed lines run from the interior of the tunnel to the shield 9. The energy and feed lines are plugged into a terminal at the end of the shield on the shield 9, which is located at the beginning of the next slot. In this way, the propulsion shield is propelled in cycles. It is also possible to alternately carry out the energy supply via the adjacent two tunnels. In this case, the slots of adjacent tunnels 4 preferably overlap. This also enables the shield to be driven forward continuously.

Es ist zusätzlich auch möglich, vor dem hinteren offenen Ende 15 des Schildes 9 Pressen anzuordnen. Nach dem Einbringen eines Teils der undurchlässigen Schicht 6 über das Ende 15 in den vom Schild 9 ge­schaffenen Hohlraum werden die Pressen tätig, die einerseits diesen eingebrachten Teil der undurch­lässigen Schicht 6 verdichten, andererseits hierbei den Vortrieb des Schildes 9 bewirken. Der Schild 9 bewegt sich auf diese Weise taktweise durch das Erdreich.It is also possible to arrange 9 presses in front of the rear open end 15 of the shield. After a part of the impermeable layer 6 has been introduced via the end 15 into the cavity created by the shield 9, the presses operate, which on the one hand compress this introduced part of the impermeable layer 6 and on the other hand cause the shield 9 to advance. The shield 9 moves cyclically through the earth in this way.
