Abstract

According to a process for carrying out civil engineering works in the area of the sole (4) of an existing waste dump, passable shafts (1, 2) designed as mutually spaced, cased large hole borings are sunk down to the waste dump sole (4). At the level of the waste dump sole (4) the shafts (1, 2) are interconnected by a passable tunnel (5), forming a continuous working room. A sufficiently large working room is thus simply created above the waste dump sole (4) for carrying out sanitation works.

Description

Verfahren zur Durchführung von Tiefbauarbeiten Procedure for performing civil engineering work
Die Erfindung betrifft ein Verfahren zur Durchführung von Bauarbeiten im Bereich der Sohle einer bestehenden Deponie.The invention relates to a method for carrying out construction work in the area of the sole of an existing landfill.
Bei Deponien für Müll und andere Abfälle besteht häufig das Problem, daß die vorhandenen Einrichtungen zur Fassung von Sickerwasser und Gas den Anforderungen nicht mehr genü¬ gen oder unbrauchbar geworden sind und daher einer Erneue¬ rung bedürfen. Ebenso treten bestehen Probleme mit der Dich¬ tigkeit der Deponiebasis, weil diese dem heutigen Stand der Anforderungen an eine Basisabdichtung nicht genügt oder weil sie durch standortbedingte Einflüsse schadhaft geworden ist. Will man die genannten Drainage- und Abdichteinrichtungen sanieren, so ist es häufig unvermeidlich, daß Bauarbeiten auf der Deponiesohle durchgeführt werden müssen. Um dies zu ermögliche, ist es notwendig, den Müllkörper einer Deponie mit Hilfe von Schachtbauwerken zu durchdringen, die je nach Höhe des Müllkörpers Tiefen von bis zu 30 m erreichen kön¬ nen. Die Herstellung solcher Schachtbauwerke in herkömmli¬ cher Grubenbauweise ist außerordentlich aufwendig und mit einer Reihe von weiteren Nachteilen verbunden.In the case of landfills for waste and other waste, there is often the problem that the existing facilities for collecting leachate and gas no longer meet the requirements or have become unusable and therefore need to be renewed. There are also problems with the tightness of the landfill base because it does not meet the current requirements for basic sealing or because it has become damaged due to location-related influences. If you want to renovate the drainage and sealing devices mentioned, it is often inevitable that construction work must be carried out on the bottom of the landfill. In order to make this possible, it is necessary to penetrate the garbage body of a landfill with the aid of shaft structures which, depending on the height of the garbage body, can reach depths of up to 30 m. The production of such shaft structures in conventional pit construction is extremely complex and has a number of further disadvantages.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Durchführung von Bauarbeiten im Bereich der Sohle einer bestehenden Deponie anzugeben, das einfach durchführbar ist und sich durch einen geringen Aufwand und ein hohes Maß an Arbeitssicherheit auszeichnet.The invention is based on the object of specifying a method for carrying out construction work in the area of the base of an existing landfill which is simple to carry out and is distinguished by a low outlay and a high level of occupational safety.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß in einem Abstand voneinander als verrohrte Großlochbohrungen ausgeführte, begehbare Schächte bis auf die Deponiesohle abgeteuft werden und daß diese Schächte in Höhe der Deponie¬ sohle durch einen begehbaren Tunnel zu einem durchgehenden Arbeitsraum miteinander verbunden werden.This object is achieved in that in accessible shafts are drilled at a distance from one another as cased large-bore bores down to the bottom of the landfill and that these shafts are connected to one another at the level of the bottom of the landfill by an accessible tunnel to form a continuous work area.
Nach dem erfindungsgemäßen Verfahren wird mit Hilfe von vergleichsweise kleinvolu igen Schächten, die durch Tunnel¬ abschnitte miteinander verbunden sind, im Bereich der Depo¬ niesohle ein ausreichend großer Arbeitsraum zur Durchführung der anstehenden Baumaßnahmen geschaffen wird. Hierbei wird durch die Ausführung der Schächte als verrohrte Großlochboh¬ rungen ein stabiler und sicherer Verbau erreicht und das Volumen des erforderlichen Aushubs minimiert. Der Platzbe¬ darf der Baustelle auf der Deponie ist hierbei gering, so daß auch eine eventuelle Störung des tatsächlichen Deponie¬ betriebes auf ein geringes Maß beschränkt werden kann. Ein Ausgasen der Deponie wird weitgehend vermieden, da die ver¬ rohrten Schachtwände geschlossen sind. Entsprechend wird auch ein unerwünschter Sauerstoffeintrag in die Deponie gering gehalten. Eine erfindungsgemäß vorgesehene Bewette¬ rung des Arbeitsraums in Höhe der Deponiesohle läßt sich bei dem erfindungsgemäßen Verfahren durch die Anordnung der Schächte sehr effektiv gestalten, da das zu bewetternde Raumvolumen gering ist und der Strömungsweg eindeutig vor¬ gegeben ist. Auch eine eventuell notwendige Wasserhaltung ist in den Schächten auf technisch einfache Weise durchführ¬ bar. Das Abteufen der Schächte kann vorteilhaft maschinell durchgeführt werden. Lediglich im Bereich der Deponiesohle werden die Schächte manuell abgeteuft, um eine Beschädigung der Basisabdichtung der Deponie zu vermeiden.According to the method according to the invention, a comparatively small-volume shaft, which is connected to one another by tunnel sections, creates a sufficiently large work space in the area of the landfill sole for carrying out the upcoming construction measures. In this case, the construction of the shafts as piped large-bore holes ensures stable and secure installation and minimizes the volume of the excavation required. The space requirement of the construction site on the landfill is small, so that any disruption to the actual operation of the landfill can be limited to a small extent. Outgassing of the landfill is largely avoided since the piped shaft walls are closed. Accordingly, an undesirable oxygen input into the landfill is kept low. In the method according to the invention, a betting of the working space at the level of the landfill base provided according to the invention can be designed very effectively by arranging the shafts, since the volume of space to be ventilated is small and the flow path is clearly specified. Any necessary water retention can also be carried out in a technically simple manner in the shafts. The sinking of the shafts can advantageously be carried out by machine. The shafts are only sunk manually in the area of the landfill floor to avoid damaging the base seal of the landfill.
Das erfindungsgemäße Verfahren eignet sich im besonderen Maße für eine fortschreitende Durchführung von Sanierungs- arbeiten. So kann erfindungsgemäß vorgesehen sein, daß nach Beendigung der Bauarbeiten in dem von zwei Schächten und einem Tunnelabschnitt gebildeten Arbeitsraum die Verrohrung eines ersten Schachtes gezogen wird und auf der anderen Seite des zweiten Schachts ein dritter verrohrter Schacht abgeteuft und durch einen begehbaren Tunnel an den zweiten Schacht angebunden wird. Auf diese Weise schließen die ein¬ zelnen Arbeitsräume in Höhe der Deponiesohle aneinander an, während auf dem Deponiekörper Schachtöffnungen in einem Abstand voneinander vorhanden sind. Mit dem bei dem Abteufen des dritten Schachtes anfallenden Aushubmaterial kann der erste Schacht wieder verfüllt werden, wenn dieser nicht bestehen bleiben soll.The method according to the invention is particularly suitable for a progressive implementation of renovation work. Thus, according to the invention it can be provided that after the completion of the construction work in the work space formed by two shafts and a tunnel section, the piping of a first shaft is drawn and a third piped shaft is sunk on the other side of the second shaft and through an accessible tunnel to the second shaft is connected. In this way, the individual work spaces adjoin one another at the level of the landfill floor, while shaft openings are spaced apart on the landfill body. The first shaft can be filled again with the excavated material from the sinking of the third shaft if it should not remain.
Das erfindungsgemäße Verfahren eignet sich ferner dazu, beim Ziehen der Verrohrung der Schächte in bestimmten Abständen Gasbrunnen auszubauen oder an geeigneten Stellen, beispiels¬ weise den Einmündungen von Drainagerohren in einen Haupt¬ sammler Kontrollschächte zu erstellen.The method according to the invention is furthermore suitable for expanding gas wells at certain intervals when pulling the piping of the shafts or for creating control shafts at suitable points, for example the outlets of drainage pipes into a main collector.
Die Erfindung wird nachfolgend anhand eines Ausführungsbei¬ spieles näher erläutert, das in der Zeichnung dargestellt ist. Es zeigenThe invention is explained in more detail below on the basis of an exemplary embodiment which is illustrated in the drawing. Show it
Fig. 1 einen Querschnitt durch eine Anordnung zweier mit einem Tunnel verbundener Schächte zur Bildung eines Arbeitsraumes für eine Sanierung von Sicker¬ wasserleitungen auf einer Deponiesohle mittels Berstlining.1 shows a cross section through an arrangement of two shafts connected with a tunnel to form a work space for the renovation of leachate pipes on a landfill base by means of burst lining.
Fig. 2 einen Schnitt durch die Schachtanordnung gemäß Fig. 1 entlang der Linie A-A. Figur 1 zeigt die Anordnung zweier durch verrohrte Großloch¬ bohrungen gebildeter Schächte 1, 2, die durch einen Depo¬ niekörper 3 bis auf eine Deponiesohle 4 abgeteuft worden sind. Die Schächte 1, 2 sind begehbar und haben einen Durchmesser von etwa 2,5 m. Ihr Mittenabstand beträgt etwa 5,5 m. Auf der Höhe der Deponiesohle 4 sind die beiden Schächte 1, 2 durch einen Tunnel 5 verbunden, der bergmän¬ nisch angefahren wird. Der Tunnel 5 ist ebenfalls begehbar und hat eine Höhe von etwa 2,0 m und eine Breite von etwa 1,0 m. Um den Tunnel 5 herum ist der Deponiekörper 3 mittels eingerammter Spieße 6 befestigt. Die Tunnelwände können zusätzlich mit Platten abgestützt und abgedichtet sein. Die beiden Schächte 1, 2 und der Tunnel 5 befinden sich unmit¬ telbar über einer beispielsweise aus Steinzeug-Drainrohren bestehenden Drainageleitung 7, die auf einer Sohlenabdich¬ tung 8 verlegt und mit einem Kiesbett 9 abgedeckt ist.Fig. 2 shows a section through the shaft arrangement of FIG. 1 along the line AA. FIG. 1 shows the arrangement of two shafts 1, 2 formed by cased large-bore holes, which have been sunk by a landfill body 3 down to a landfill base 4. The shafts 1, 2 are accessible and have a diameter of approximately 2.5 m. Their center distance is about 5.5 m. At the level of the landfill base 4, the two shafts 1, 2 are connected by a tunnel 5 which is mined. The tunnel 5 is also accessible and has a height of approximately 2.0 m and a width of approximately 1.0 m. The landfill body 3 is fastened around the tunnel 5 by means of driven spikes 6. The tunnel walls can also be supported and sealed with plates. The two shafts 1, 2 and the tunnel 5 are located directly above a drainage line 7, for example made of stoneware drainpipes, which is laid on a sole seal 8 and covered with a gravel bed 9.
Durch die beschriebene Anordnung der beiden durch den Tunnel 5 verbundenen Schächte 1, 2 wird über der Drainageleitung 7 ein Arbeitsraum geschaffen, der es ermöglicht, wie in FigurThe described arrangement of the two shafts 1, 2 connected by the tunnel 5 creates a working space above the drainage line 7, which makes it possible, as in FIG
1 veranschaulicht, nach dem bekannten Berstlining-Verfahren die Drainageleitung 7 zu erneuern. Hierzu werden die Stein¬ zeugrohre innerhalb des Arbeitsraumes ausgebaut. Anschlie¬ ßend wird ein neuer Rohrleitungsstrang 10, an dessen Ende eine Berstlining-Rakete 11 befestigt ist, durch den Schacht1 illustrates renewing the drainage line 7 according to the known burst lining method. For this purpose, the stoneware pipes are removed within the work area. A new pipeline string 10, at the end of which a burst lining rocket 11 is attached, is then passed through the shaft
2 in den Arbeitsraum eingeführt und mit Hilfe der Berstli¬ ning-Rakete 11 unter gleichzeitiger Zerstörung der vorhan¬ denen Steinzeugrohre in den vorhandenen Rohrkanal der Drai¬ nageleitung 7 eingezogen. Der Vortrieb wird hierbei durch ein zuvor in die Drainageleitung 7 eingeführtes Zugseil 12 unterstützt. Das Zugseil 12 verläuft durch die Drainagelei¬ tung 7 zu einer in geeigneter Entfernung von den Schächten 1,2 über der Drainageleitung 7 aufgebauten zweiten Schacht¬ anordnung oder zu einer neben der Deponie angeordneten End- grübe und wird dort zu einer Winde geführt. Beim Einziehen wird der Rohrleitungsstrang 10 an Führungsrollen 13 geführt, die im Schacht 2 angeordnet sind. Auf dem Deponiekörper 3 sorgt ein Rollenwagen 14 für die Führung des Rohrleitungs- stanges.2 inserted into the work space and drawn into the existing pipe channel of the drainage line 7 with the help of the bursting rocket 11 while simultaneously destroying the existing stoneware pipes. The propulsion is supported by a pull rope 12 previously inserted into the drainage line 7. The traction cable 12 runs through the drainage line 7 to a second shaft arrangement which is constructed at a suitable distance from the shafts 1, 2 above the drainage line 7 or to an end line arranged next to the landfill. dig and is led there to a winch. When pulling in the pipeline 10 is guided on guide rollers 13 which are arranged in the shaft 2. On the landfill body 3, a roller carriage 14 ensures the guidance of the pipeline rod.
Nachdem der Rohrstrang 10 in den einen in Figur 1 links dargestellten Abschnitt der Drainageleitung 7 eingezogen ist, wird nach dem gleichen Verfahren über den Schacht 1 ein weiterer Rohrleitungsstrang in den anderen, in Figur 1 rec¬ hts dargestellten Abschnitt der Drainageleitung 7 eingezogen und mit dem Rohrleitungsstrang 10 verbunden.After the pipe string 10 has been drawn into a section of the drainage line 7 shown on the left in FIG. 1, another pipe string is drawn into the other section of the drainage line 7 shown in FIG Pipeline string 10 connected.
Während der Durchführung dieser Bauarbeiten wird der Ar¬ beitsraum bewettert, indem beispielsweise mit Hilfe eines Gebläses dem Schacht 1 Frischluft zugeführt wird, die am Fuß des Schachts 1 über den Tunnel 5 in den Schacht 2 gelangt und durch diesen den Arbeitsraum wieder verläßt.While this construction work is being carried out, the work space is ventilated, for example by supplying fresh air to the shaft 1 with the aid of a blower.
Nach Beendigung der Bauarbeiten wird die Verrohrung der Schächte 1, 2 gezogen und die Schächte werden wieder mit Deponiematerial verfüllt.After completion of the construction work, the piping of the shafts 1, 2 is pulled and the shafts are filled with landfill material again.
Das erfindungsgemäße Verfahren eignet sich auch zur Herstel¬ lung eines Hauptsammlers unter einer Deponie. Hierbei werden nacheinander zwei verrohrte Schächte in einem Abstand von ca. 7,5 m bis auf die Basisabdichtung abgeteuft und zwischen den Schächten eine Tunnelverbindung hergestellt. Anschlie¬ ßend werden in dem so geschaffenen Arbeitsraum die Sammler¬ rohre in einem Rohrbett auf der Deponiesohle verlegt, mit einer Kiesschüttung ummantelt und wieder verfüllt. Ist ein Abschnitt des Hauptsammlers eingebaut, wird die Verrohrung des ersten Schachtes gezogen und hinter dem zweiten Schacht wird ein dritter Schacht abgeteuft, der wiederum über eine TunnelVerbindung mit dem zweiten Schacht verbunden wird. Der Ausbau des Hauptsammlers kann nun von dem zweiten Schacht zum dritten Schacht erfolgen. In dieser Weise fortschreitend wird der Rohrleitungsstrang des Sammlers erstellt. The method according to the invention is also suitable for producing a main collector under a landfill. Here, two cased shafts are sunk one after the other at a distance of approx. 7.5 m to the base seal and a tunnel connection is established between the shafts. The collector tubes are then laid in a tube bed on the landfill base in the work space thus created, covered with a gravel fill and filled again. If a section of the main collector is installed, the piping of the first shaft is pulled and behind the second shaft a third shaft is sunk, which in turn is via a Tunnel connection is connected to the second shaft. The main collector can now be expanded from the second shaft to the third shaft. Progressively, the collector pipeline is created.
