Abstract

The impervious sealing and the production method for it make it possible to replace the expensive methods of shield tunnelling or freezing and as a result eliminate interference with the ground-water balance and prepare the ground masses to be excavated in such a way that they can be continuously excavated in timed sequence with the subterranean construction from a secured position and in the dry. This is achieved by virtue of the fact that the impervious sealing consists of an elastic sealing jacket (3) which is formed from sealing walls (2) arranged in the form of a canopy, screen, housing or the like and which hermetically seals off the ground masses (5) to be excavated from the ground water (4) and/or from air. In the production method provided for this, the ground masses (5) in place of a site to be driven dry are sealed off from the ground water (4) and/or the air by a sealing jacket, are dewatered, are compacted under the pressure of the ground water (4) in place on the outside of the sealing jacket (3) and/or are stabilised by applying a vacuum. <IMAGE>

Description

Die Erfindung betrifft eine Abdichtung sowie ein Herstellungsverfahren hierfür zur Schaffung tragfähiger, abbaufähiger Bodenmassen für die Ausführung von Untertagebauwerken, wie Hohlraumbauten od. dgl.The invention relates to a seal and a manufacturing method therefor to create stable, degradable soil masses for the execution of underground structures, such as cavity structures or the like.

Die Grundwasserabsenkung als Bauhilfsmaßnahme bei der Ausführung von Untertagebauwerken unterhalb des Grundwasserspiegels ist aus Rechts- und Umweltgründen möglichst auszuschließen. Um dennoch die tiefen "offenen" Baugruben unterhalb des Grundwasserspiegels im Trockenen ausführen zu können, ist es erforderlich, den Baustellenbereich mit wasserdichten Verbauwänden zu umschließen, die bis zur Tiefe einer wasserundurchlässigen Bodenschicht geführt werden müssen.The lowering of the groundwater as a construction measure for the construction of underground structures below the water table is to be excluded as far as possible for legal and environmental reasons. In order to be able to carry out the deep "open" excavation pits below the groundwater table in the dry, it is necessary to enclose the construction site area with watertight sheeting walls, which must be led to the depth of a water-impermeable layer of soil.

Da solche Verbauwände außer der großen Tiefe auch gegen den äußeren Druck des Grundwassers bemessen sein müssen, ist diese Bauweise sehr aufwendig.Since such shoring walls have to be dimensioned against the external pressure of the groundwater in addition to the great depth, this construction method is very complex.

Noch aufwendiger sind die unterirdischen "geschlossenen" Baugruben. Solche Baugruben werden im Schildvortrieb unter Druckluft oder bei flüssigkeitsgestützter Ortsbrust aufgefahren, oder das Grundwasser wird im Baustellenbereich vereist.The underground "closed" construction pits are even more complex. Such excavation pits are excavated in shield driving under compressed air or with a liquid-supported face, or the groundwater is iced up in the construction site area.

Die genannten Verfahren mit geschlossenen Baugruben sind extrem aufwendig.The above-mentioned methods with closed construction pits are extremely complex.

Ausgehend vom Stand der Technik ist es daher Aufgabe der Erfindung, eine Abdichtung und ein Verfahren.zu schaffen, mittels denen eine trockene Baugrube geschaffen werden kann, und zwar ohne nachhaltige Beeinflussung des Grundwasserspiegels.Starting from the prior art, it is therefore an object of the invention to provide a seal and a method by means of which a dry excavation pit can be created, and without lasting influence on the groundwater level.

Diese Aufgabe wird bei der Abdichtung gemäß der Erfindung mit den Merkmalen des Anspruchs 1 und bei dem erfindungsgemäßen Verfahren mit den Merkmalen des Anspruchs 6 gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.This object is achieved in the sealing according to the invention with the features of claim 1 and in the method according to the invention with the features of claim 6. Advantageous further developments result from the subclaims.

Die erfindungsgemäß vorgesehene Abdichtung, die zur Schaffung tragfähiger, abbaufähiger Bodenmassen für die Ausführung von Untertagebauwerken, wie Hohlraumbauten od. dgl., dient, besteht aus einer elastischen Abdichthülle, die aus in Form eines Daches, Schirms, eines Gehäuses od. dgl. angeordneten Dichtwänden gebildet ist und die abzubauenden Bodenmassen hermetisch gegen Grundwasser und/oder gegen Luft abdichtet.The seal provided according to the invention, which is used to create load-bearing, degradable floor masses for the execution of underground structures, such as cavity structures or the like, consists of an elastic sealing sheath, which consists of sealing walls arranged in the form of a roof, screen, housing or the like is formed and the soil mass to be mined hermetically seals against groundwater and / or air.

Von besonderem Vorteil ist es, wenn die elastischen Dichtwände der Abdichthülle aus einem ausgehärteten, durch Injizieren unter Druck in den Boden einbringbaren Gemisch auf der Basis Bentonit/Füller/Zement und/oder Feststoff/Bitumen bestehen.It is particularly advantageous if the elastic sealing walls of the sealing cover consist of a hardened mixture based on bentonite / filler / cement and / or solid / bitumen, which can be introduced into the ground by injection under pressure.

Zweckmäßigerweise ist jede Dichtwand der Abdichthülle derart ausgebildet, daß sie aus durch Injizieren gebildeten Dichtungslamellen und/oder sich überschneidenden Säulen besteht.Each sealing wall of the sealing sleeve is expediently designed such that it consists of sealing lamellae formed by injection and / or overlapping columns.

Eine besonders vorteilhafte Ausführungsform der Abdichtung ergibt sich, wenn die Dichtwände der Abdichthülle von einer an der Oberfläche oder unterhalb dieser liegenden zentralen Firstlinie aus divergierend schräg nach unten bis in den wasserundurchlässigen Boden verlaufen. Diese zentrale Firstlinie, die ein Arbeitstunnel od. dgl. sein kann, stellt bei der dachartig oder schirmartig ausgebildeten Abdichthülle dann, im Querschnitt gesehen, die obere Spitze des betreffenden Querschnittdreicks dar. Hierdurch wird in vorteilhafter Weise ermöglicht, mit der Abdichthülle eine geringstmögliche Oberfläche bei größtmöglichem Effekt vorzusehen.A particularly advantageous embodiment of the seal is obtained if the sealing walls of the sealing sleeve protrude from one on the surface or below it central ridge line from diverging diagonally down to the waterproof floor. This central ridge line, which can be a working tunnel or the like, then represents the upper tip of the cross-sectional triangle in question in the case of the roof-like or umbrella-like sealing sleeve. This advantageously enables the sealing sleeve to have the smallest possible surface area to provide the greatest possible effect.

In weiterer Ausgestaltung der Erfindung ist es auch möglich, die Abdichthülle bodenseitig unterhalb der abzubauenden Bodenmassen durch einen flächigen Soilcrete-Körper zu verschließen, der aus einer verfestigten, durch Injizieren eingebrachten Suspension besteht.In a further embodiment of the invention, it is also possible to close the sealing cover on the bottom side below the soil mass to be dismantled by means of a flat soil concrete body which consists of a solidified suspension which is introduced by injection.

Das erfindungsgemäße Verfahren ermöglicht es, die abzubauenden und die untertage verbleibenden Bodenmassen so aufzubereiten, daß deren Abbau kontinuierlich, aus gesicherter Position und im Trockenen erfolgen kann. Dabei ist das erfinderische Verfahren weniger aufwendig als die bekannten Verfahren des Schildvortriebs oder der Vereisung.The method according to the invention makes it possible to prepare the soil masses to be mined and the remaining underground so that they can be mined continuously, from a secured position and in the dry. The inventive method is less expensive than the known methods of shield driving or icing.

Bei dem Verfahren gemäß der Erfindung werden die in einer Abdichthülle der trocken vorzutreibenden Baustelle anstehenden Bodenmassen gegen das Grundwasser und die Luft abgedichtet, entwässert, unter dem Druck des an der Außenseite der Abdichthülle anstehenden Grundwassers verdichtet und/oder durch Vakuumbeaufschlagung stabilisiert, so daß ein belastbarer, standfester und trockener Boden gewonnen wird, der im Takt des Baufortschritts des Untertagebauwerks kontinuierlich ausgebildet und aus geschützter Position und im Trockenen abgebaut werden kann.In the method according to the invention, the soil masses present in a sealing envelope of the construction site to be driven dry are sealed against the groundwater and the air, dewatered, compressed under the pressure of the groundwater present on the outside of the sealing envelope and / or stabilized by vacuum, so that a more resilient , stable and dry soil is obtained, which is continuous with the progress of construction of the underground structure trained and can be dismantled from a protected position and dry.

Das erfindungsgemäße Verfahren schließt die Nachteile der bekannten wasserdichten Umschließungsverfahren weitestgehend aus und beschränkt sich auf die Entwässerung des Bodens im unmittelbaren Bereich der Baugrube bzw. des Untertagebauwerks.The method according to the invention largely excludes the disadvantages of the known watertight containment methods and is limited to the drainage of the soil in the immediate area of the excavation pit or the underground structure.

Dieser Vorteil wird vor allen Dingen dadurch erreicht, daß eine Abdichthülle gebildet wird, die den Bereich der Baustelle für die abzubauenden Bodenmassen gegen das Grundwasser und die Luft abdichtet.This advantage is achieved above all in that a sealing sheath is formed which seals the area of the construction site against the groundwater and the air for the soil mass to be mined.

Die Abdichthülle wird aus Dichtwänden gebildet, deren Form den örtlichen Verhältnissen angepaßt ist und die durch Injizieren einer Flüssigkeitsmischung auf der Basis Bentonit/Füller/Zement oder als Feststoff/ Bitumen-Gemisch als hochgespannter Suspensiönsstrahl mit Drücken von 300 bis 600 bar in die abzudichtenden Bodenmassen ausgebildet werden.The sealing sleeve is formed from sealing walls, the shape of which is adapted to the local conditions and which is formed by injecting a liquid mixture based on bentonite / filler / cement or as a solid / bitumen mixture as a high-tension suspension jet with pressures of 300 to 600 bar into the soil to be sealed will.

Die Dichtheit der Abdichthülle wird dadurch gesichert, daß die Dichtwände an ausgespülten und erodierten Stellen mit Injektionsmitteln bei Drücken zwischen 50 und 100 bar nachinjiziert werden.The tightness of the sealing cover is ensured by injecting the sealing walls at rinsed and eroded locations with injection agents at pressures between 50 and 100 bar.

Das Ergebnis des Injizierens und Nachinjizierens ist eine homogene, elastische und nach Tiefe, Breite und Höhe exakt bemessene Dichtwand, die aus alterungsbeständigem und umweltfreundlichem Material hergestellt ist.The result of injecting and re-injecting is a homogeneous, elastic and precisely dimensioned according to depth, width and height, which is made of age-resistant and environmentally friendly material.

Die von der Abdichthülle umschlossene Baugrube kann dann für den eigentlichen Bauvorgang entwässert und trockengehalten werden.The construction pit enclosed by the sealing envelope can then be dewatered and kept dry for the actual construction process.

Ein wesentlicher Vorteil des erfindungsgemäßen Verfahrens besteht darin, daß die Abdichthülle in der Lage ist, sich der Volumenverminderung der Bodenmassen elastisch anzupassen, ohne die Abdichtung zu gefährden. Ein weiterer entscheidender Vorteil des Verfahrens besteht darin, daß die Abdichthülle in der Lage ist, die Druckkräfte des Grundwassers auf deren Außenhaut so aufzunehmen, daß eine zusätzliche Verdichtung des Bodens im eingeschlossenen Entwässerungsbereich ausgeglichen wird.An important advantage of the method according to the invention is that the sealing cover is able to adapt elastically to the volume reduction of the floor masses without endangering the sealing. Another decisive advantage of the method is that the sealing cover is able to absorb the compressive forces of the groundwater on its outer skin in such a way that an additional compaction of the soil in the enclosed drainage area is compensated for.

Das erfindungsgemäße Verfahren bietet den weiteren Vorteil, daß die Abdichthülle bei unerwarteten Undichtheiten durch Nachverpressen mit Hilfe von Ventilrohren nachgedichtet werden kann.The method according to the invention offers the further advantage that the sealing sleeve can be re-sealed in the event of unexpected leaks by repressing with the aid of valve tubes.

Die Abdichthülle kann auch als zusätzliche Sicherungsmaßnahme gegen Luftverluste bei Druckluftvortrieben in geringer Bodenüberdeckung verwendet werden.The sealing sleeve can also be used as an additional safety measure against air loss in compressed air drives with little ground cover.

Zur Vermeidung von übermäßiger Volumenminderung des Bodens kann dem Injektionsmittel ein Quellmittel beigegeben werden.To avoid excessive volume reduction of the soil, a swelling agent can be added to the injection agent.

Das Verfahren gemäß der Erfindung bietet auch die Möglichkeit, die Abdichthülle nach dem Bodenaufsprengverfahren (Soil-fracturing) herzustellen und durch Nachinjektion zu stabilisieren.The method according to the invention also offers the possibility of producing the sealing cover by the soil blasting method (soil fracturing) and stabilizing it by post-injection.

Fig 1 zeigt eine von Dichtwänden 2 gebildete Abdichthülle 3, die durch Vakuum-Tiefbrunnen 6 vom Grundwasserspiegel 4 bis auf eine Mergelschicht 8 entwässert wird, so daß U-Bahn-Röhren 1 im Trockenen vorgebaut werden können. Der Außendruck des im Schluff oder Feinsand 7 stehenden Grundwassers 4 wird von den Dichtwänden 2 aufgefangen. Die Dichtwände 2 sind in die Mergelschicht 8 eingebunden. Die Baustelle liegt unterhalb der Bodenanschüttung.Fig. 1 shows a sealing shell 3 formed by sealing walls 2, which is dewatered by vacuum deep wells 6 from the groundwater level 4 to a marl layer 8, so that underground tubes 1 can be pre-built in the dry. The external pressure of the groundwater 4 standing in silt or fine sand 7 is absorbed by the sealing walls 2. The sealing walls 2 are integrated in the marl layer 8. The construction site is below the ground level.

In Fig. 2 ist die unterirdische Verlegung von U-Bahn-Tunneln 1 unter der Oberkante 10 des Geländes gezeigt. Die Dichtwände 2 schirmen den Grundwasserspiegel 4 ab. Der von den Dichtwänden 2 umschlossene Boden 5 wird durch die Vakuumbrunnen 6, die in den beiden Arbeitsstollen 11 angeordnet sind, entwässert. Dadurch entsteht zwischen den Dichtwänden 2 eine entwässerte und stabilisierte Bodenzone 5, worin der Vortrieb trocken erfolgen kann.2 shows the underground laying of subway tunnels 1 under the upper edge 10 of the site. The sealing walls 2 shield the groundwater level 4. The bottom 5 enclosed by the sealing walls 2 is dewatered by the vacuum wells 6, which are arranged in the two working tunnels 11. Thereby there is a drained and stabilized soil zone 5 between the sealing walls 2, in which the propulsion can take place dry.

Fig. 3 zeigt die Verlegung von U-Bahn-Röhren 1, die unter dem Gebäude 12 im Trockenen verlegt werden. Hierfür wird der von den Dichtwänden 2 eingeschlossene Boden 5 von den Vakuum-Tiefbrunnen 6 bis auf die Mergelschicht B entwässert, so daß das Untertagebauwerk im entwässerten und stabilisierten. Boden 5 erstellt werden kann.Fig. 3 shows the laying of underground tubes 1, which are laid under the building 12 in the dry. For this purpose, the floor 5 enclosed by the sealing walls 2 is dewatered by the vacuum deep wells 6 down to the marl layer B, so that the underground structure in the dewatered and stabilized. Soil 5 can be created.

In Fig. 4 ist eine Ausführung dargestellt, bei der die Abdichthülle 3 aus dachförmig angeordneten Dichtwänden 2 besteht. Bei dieser Anordnung wird ein zusätzlicher Verdichtungseffekt durch den Druck des Außenwasserspiegels 4 auf die eingeschlossenen Bodenmassen 5 erreicht. Einer Volumenminderung passen sich die elastischen Dichtwände 2 unmittelbar ohne Beeinträchtigung der Abdichtungsfunktion an. Das Dach der Abdichthülle ist bei dieser Ausführung deutlich zur Oberfläche 13 hin hochgezogen.FIG. 4 shows an embodiment in which the sealing sleeve 3 consists of sealing walls 2 arranged in a roof shape. In this arrangement, an additional compaction effect is achieved by the pressure of the outside water level 4 on the enclosed soil masses 5. The elastic sealing walls 2 adapt to a volume reduction directly without impairing the sealing function. In this embodiment, the roof of the sealing sleeve is clearly pulled up to surface 13.

Bei der Ausführung nach Fig. 5 ist das Dach, d.h. die Dichtwände 2, dagegen deutlich zur Mergelschicht 8 heruntergezogen. Nach dieser Ausgestaltung ist das Volumen der Abdichthülle 3 durch die tiefgesetzten Dichtwände 2 eingeschränkt und der Einwirkbereich eng auf die Entwässerungszone 5 beschränkt. Diese Ausführungsform ist besonders geeignet für tiefliegende Baugruben, um bei einer inneren Vakuum-Entwässerung außer dem Außenwasser 4 auch den Luftzutritt von außen zu unterbinden und damit den Unterdruck für die damit verbundene Bodenstabilisierung besonders wirksam werden zu lassen.In the embodiment according to Fig. 5, the roof, i.e. the sealing walls 2, however, clearly pulled down to marl layer 8. According to this embodiment, the volume of the sealing sleeve 3 is limited by the recessed sealing walls 2 and the area of action is narrowly restricted to the drainage zone 5. This embodiment is particularly suitable for deep-lying construction pits, in order to prevent air from entering from outside in addition to the outside water 4 in the case of an internal vacuum drainage and thus to make the vacuum particularly effective for the associated soil stabilization.

Fig. 6 zeigt eine Ausführungsform, bei der die Dichtwände 2 tief in die Mergelschicht 8 eingelassen sind, so daß die eingeschlossene Abdichthülle 3 räumlich stark eingeschränkt ausgebildet werden kann. Dadurch wird das Volumen des zu stabilisierenden und zu entwässernden Bodens 5 bei dieser Ausführungsform in günstiger Weise sehr klein. Der Vortrieb der beiden U-Bahnröhren 1 erfolgt im Trockenen. Der Abbau der Bodenmassen aus der Mergelschicht 8 wird dadurch erleichtert, daß diese durch zusätzliche Injektionen nach dem Soil-fracturing-Verfahren verdichtet und stabilisiert werden können. Ein Soilcrete-Körper 14 unter den Profilen der U-Bahn-Röhren 1 dient der Absicherung des Hohlraumbauwerks zur Tiefe hin.Fig. 6 shows an embodiment in which the sealing walls 2 are embedded deeply in the marl layer 8, so that the enclosed sealing sleeve 3 can be made very spatially restricted. As a result, the volume of the soil 5 to be stabilized and drained is advantageously very small in this embodiment. The two subway tubes 1 are driven in the dry. The degradation of the soil mass from the marl layer 8 is facilitated in that it can be compacted and stabilized by additional injections using the soil fracturing method. A Soilcrete body 14 under the profiles of the subway tubes 1 serves to secure the hollow structure to the depth.

Fig. 7 zeigt Grundrisse der elastischen Dichtwand 2, die aus Dichtungslamellen 15 oder aus überschneidenden Säulen 16 oder aus deren Kombinationen ausgebildet sein können.Fig. 7 shows floor plans of the elastic sealing wall 2, which can be formed from sealing strips 15 or from intersecting columns 16 or from their combinations.

Etwaige weitere oder zusätzliche Merkmale der Erfindung, die hicht in den Ansprüchen aufgeführt sind, ergeben sich im übrigen deutlich einzeln oder in Kombination miteinander aus der Beschreibung und/oder der Zeichnung.Any further or additional features of the invention, which are not set out in the claims, are moreover clearly evident individually or in combination with one another from the description and / or the drawing.
