Abstract

The procedure uses a subterranean curtain wall trench cutting machine (1), and the trench (2) is supported in the conventional way by a liq. Binding agents (7) and/or solids (8) are fed into the liq. (3) via a feed tube (4), with outlet (5) below the liq. surface (6). The feed pump (9) of the trench cutter removes the support liq. from the trench, and returns it to the trench via the pump hose (10). The height of the hose outlet (11) is different from that of the pump inlet (12). USE - Cutting trench to make retention wall buried in ground.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung einer Dichtwand.The invention relates to a method for producing a Sealing wall.

Durch die deutsche OS 36 27 872 ist eine Mischvorrichtung be­ kannt, mit der eine Dichtwandmasse mit hohem Feststoffgehalt in eine in einem Dichtwandschlitz vorhandene Suspension einge­ bracht wird. Die Mischvorrichtung besteht aus einem länglichen Gestell, in dem über eine Förderleitung die Dichtwandmasse ei­ nem Verteilerrohr und von dort wiederum mehreren Austrittsroh­ ren zugeleitet wird. Durch Vertikalbewegung des Verteilers soll die eingebrachte Dichtwandmischung mit der Stützsuspension ver­ mischt werden.Through the German OS 36 27 872 a mixing device be with which a bulkhead with high solids content in an existing suspension in a sealing wall slot is brought. The mixing device consists of an elongated Frame in which the bulkhead mass ei a manifold and from there in turn several outlet pipes is fed. By vertical movement of the distributor should ver the mixture of cut-in walls introduced with the support suspension to be mixed.

Nachteilig bei dieser Mischvorrichtung ist vor allem, daß neben dem Gerät zur Herstellung des Erdschlitzes, einem Schlitzwand­ greifer oder einer Schlitzwandfräse, eine zusätzliche Geräte­ einrichtung zum Einbringen der Dichtwandmasse und zum Mischen erforderlich ist. Weiterhin haben Versuche gezeigt, daß das verteilte Einbringen der Dichtwandmasse in die Stützsuspension, auch wenn es noch durch Rührwerkzeuge, wie in der OS 36 27 872 erwähnt, unterstützt wird, keine in allen Bereichen des Erd­ schlitzes homogene Durchmischung bewirken kann.The main disadvantage of this mixing device is that in addition to the device for producing the earth slot, a diaphragm wall gripper or a trench cutter, an additional device device for introducing the bulkhead mass and for mixing is required. Experiments have also shown that the distributed introduction of the sealing wall mass into the support suspension, even if it is still by stirring tools, as in OS 36 27 872 mentioned, supported, none in all areas of the world slit homogeneous mixing can cause.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Herstellung einer Dichtwand anzugeben, das den Einsatz vorhan­ dener Geräte für den Schlitzwandaushub ermöglicht und somit die Kosten gegenüber dem Verfahren des Standes der Technik wesent­ lich senkt und die Qualität der Dichtwandmischung wesentlich verbessert.The invention has for its object a method for Manufacture of a sealing wall to specify that the use existing which enables devices for the trench wall excavation and thus the Costs essential compared to the prior art method lowers and the quality of the sealing wall mix significantly improved.

Diese Aufgabe wird durch den kennzeichnenden Teil des Anspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.This task is accomplished by the characterizing part of the claim 1 solved. Further advantageous embodiments of the invention are specified in the subclaims.

Ein wesentlicher Vorteil des erfindungsgemäßen Verfahrens be­ steht darin, daß sofort, nachdem die Schlitzwandfräse den Aus­ hub beendet hat, mit der Zugabe von Bindemittel und/oder Fest­ stoffen begonnen werden kann, wobei die wesentlichen Komponen­ ten der Schlitzwandfräse, nämlich die Pumpe und die Fräsräder, für den Mischvorgang verwendet werden. Hierbei muß nur der För­ derschlauch, der beim Aushub die mit Bodenmaterial angereicher­ te Suspension zur Regenerieranlage leitet, von der Regenerier­ anlage abgekoppelt werden und das offene Ende in den Erdschlitz bzw. in die Suspension eingehängt werden.A major advantage of the method according to the invention is that immediately after the trench cutter the off stroke has ended with the addition of binder and / or solid can be started with the essential components ten of the trench cutter, namely the pump and the cutting wheels, be used for the mixing process. Here only the För the hose that enriches the soil material during excavation te suspension leads to the regeneration plant, from the regeneration system and the open end in the earth slot or suspended in the suspension.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines bevorzugten Ausführungs­ beispiels, das anhand der Zeichnung näher erläutert wird.Further features and advantages of the invention result from the following description of a preferred embodiment example, which is explained in more detail with reference to the drawing.

Fig. 1 zeigt einen Erdschlitz 2 in einem vertikalen Längs­ schnitt, in dem eine Schlitzwandfräse 1 den Aushub bis zur End­ teufe 14 fertiggestellt hat. Der Erdschlitz 2 ist mit einer Stützflüssigkeit 3, beispielsweise einer Bentonitsuspension, bis zur Oberfläche 6 gefüllt. Im oberen Bereich der Stütz­ flüssigkeit 3 wird die Zuführungsleitung 4 zum Einbringen ei­ nes Bindemittels 7 und/oder von Feststoffen 8 eingetaucht. Der Pumpenförderschlauch 10 ist von der Regenerieranlage abgekop­ pelt und ist ebenfalls unmittelbar neben der Zuführungsleitung 4 in die Stützflüssigkeit 3 eingetaucht. Die Austrittsöffnungen 5 und 11 liegen auf gleicher Höhenlage. Dadurch findet in die­ sem Bereich sofort eine intensive Durchmischung statt. Die Pumpe 9 der Schlitzwandfräse 1 fördert aus dem tieferen Bereich des Erdschlitzes 2 die Stützflüssigkeit 3 über den Pumpenför­ derschlauch 10 nach oben. Hierbei werden vorzugsweise Pumpen­ leistungen zwischen 200 und 300 m3/h eingestellt. Bei einem Großversuch in einem Erdschlitz mit den Abmessungen L/B/H= 2,80/0,60/30 m, also mit einem Suspensionsvolumen von ca. 50 m3 wurden 12 t Zement in 30 min über die Zuführungslei­ tung 4 zugegeben. Hierbei leistete die Förderpumpe 9 i. M. 250 m3/h, also in der Zeit von 30 min ca. 125 m3. Während des Einblasens des Zements wurde also das Suspensionsvolumen ca. 2,5 mal umgepumpt. Schon dabei wurde eine sehr gleichmäßi­ ge Durchmischung zwischen Stützflüssigkeit 3 und Bindemittel 7 erreicht. Eine weitere Homogenisierung der Durchmischung wur­ de erreicht, indem nach der Beendigung der Zementzugabe die Mischung weitere 30 min mit einer Pumpenleistung von 250 m3/h umgepumpt wurde. Hierbei wurde die Schlitzwandfräse mehrmals aus der tiefsten Lage in die höchste Lage und umgekehrt bewegt. Durch gleichzeitiges Drehen der Fräsräder 13 in Richtung der Eintrittsöffnung 12 der Förderpumpe 9 wurde bewirkt, daß die Suspension aus allen Randbereichen in den Umpumpprozeß einbe­ zogen wurde.
Bezugszeichenliste: Fig. 1 shows an earth slot 2 in a vertical longitudinal section, in which a trench cutter 1, the excavation to the end 14 has completed. The earth slot 2 is filled with a supporting liquid 3 , for example a bentonite suspension, up to the surface 6 . In the upper region of the support liquid 3 , the feed line 4 for introducing egg nes binder 7 and / or solids 8 is immersed. The pump delivery hose 10 is uncoupled from the regeneration system and is also immersed directly next to the feed line 4 in the supporting liquid 3 . The outlet openings 5 and 11 are at the same height. As a result, intensive mixing takes place immediately in this area. The pump 9 of the trench cutter 1 conveys the support liquid 3 from the lower region of the earth slot 2 via the pump hose 10 upwards. Here pump outputs are preferably set between 200 and 300 m 3 / h. In a large-scale test in an earth slot with the dimensions L / W / H = 2.80 / 0.60 / 30 m, that is to say with a suspension volume of approximately 50 m 3 , 12 t of cement were added in 30 minutes via the feed line 4 . The feed pump 9 i. M. 250 m 3 / h, i.e. in the time of 30 min approx. 125 m 3 . During the blowing in of the cement, the suspension volume was pumped around 2.5 times. A very uniform mixing between the supporting liquid 3 and the binder 7 was already achieved. A further homogenization of the mixing was achieved by pumping the mixture for a further 30 min at a pump output of 250 m 3 / h after the cement addition had ended. The trench cutter was moved several times from the lowest position to the highest position and vice versa. By simultaneously turning the cutting wheels 13 in the direction of the inlet opening 12 of the feed pump 9 , it was caused that the suspension was drawn in from all peripheral areas in the pumping process.
