Description
Schalung zum Herstellen von Betonwänden unter Wasser, beispielsweise von Molen Die Erfindung betrifft eine Schalurig zum Herstellen von Betqnwändeii nritpg Wasser, beispielsweise von Molen.Formwork for making concrete walls under water, for example von Molen The invention relates to a Schalurig for making Betqnwändeii nritpg water, for example from moles.
Bisher wurden solche $chalungen durch $ _pundwände, Blechplatten usw. gebildet, Was erhebliche Kosten verursacht, insbesondere auch für- den Transport der Schalungsteile zur Baustelle, Es ist bei Unterwasserbauten auch schon bekannt, Schläuche oder Säcke zu benutzen, in die der Beton eingefüllt wird. Bei dieser Verfahrensweise werden die Schläuche oder Säcke waagerecht liegend auf dem Meeresgrund angeordnet, wodurch sieh nach Füllung der Schläuche mit Beton Fundamente herstellen lassen.Previously, such $ were chalungen by $ _pundwände formed sheet metal panels, etc. What would be extremely expensive, especially for- transporting the formwork parts to the construction site, it is at underwater structures already known to use hoses or bags in which the concrete is poured . In this procedure, the hoses or bags are arranged horizontally on the seabed, which means that foundations can be made after the hoses have been filled with concrete.
Das Herstellen von Dämmen ist nach diesem Verfahren ebenfalls möglich. Hierbei werden zunächst zahlreiche Schläuche parallel zueinander auf dem Meeresboden in einer Schicht ausgelegt. Auf die erste Schicht folgt eine zweite Schlauchschicht oder mehrere Schichten, deren Schläuche die Fugen der vorhergehenden Schicht überdecken. Es entsteht damit ein Damm, der im Querschnitt etwa die Form eines gleichseitigen Dreiecks hat, wodurch sehr viel Material verbraucht wird. Die Böschungen des Dammes sind schwach geneigt. Es ist aber bei Molen erwünscht, eine möglichst senkrechte Wand zu erhalten, damit Schiffe bei jedem Wasserstand anlegen können.The construction of dams is also possible using this method. Here, numerous hoses are first placed parallel to one another on the sea floor laid out in one layer. The first layer is followed by a second layer of tubing or several layers, the tubes of which cover the joints of the previous layer. This creates a dam, which in cross-section roughly has the shape of an equilateral Triangle, which consumes a lot of material. The embankments of the dam are weakly inclined. In the case of moles, however, it is desirable to be as vertical as possible Wall so that ships can dock at any water level.
Bei der Erfindung wird auch von einer Schalung ausgegangen, die wasserdichte, unstarre Wände in Form einer sack- oder schlauchförmigen Hülle aufweist. Der Erfindung liegt die Aufgabe zugrunde, eine derartige Schalung so auszubilden, daß unter Wasser Wände mit lotrechter Wandung hergestellt werden können. Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß die oben offene Hülle an einem Halterahmen aufgehängt ist und ihre Wände durch Einschnürungen oder Abstandhalter von oben nach unten in Längsstreifen unterteilt sind, deren Breite etwa der Stärke der herzustellenden Betonwand entspricht.The invention is also based on a formwork that is waterproof, having non-rigid walls in the form of a sack-shaped or hose-shaped shell. The invention The object is to design such formwork so that under water Walls with perpendicular walls can be produced. This task is carried out according to the invention solved in that the top open shell is suspended from a holding frame is and its walls through constrictions or spacers from top to bottom in Longitudinal strips are divided, the width of which is approximately the thickness of the one to be produced Concrete wall corresponds.
Beim Arbeiten mit der Schalung wird die oben offene Hülle mittels eines Hebezeugs bis zum Grund ins Wasser eingebracht. Dann wird die Hülse mittels eines eingeführten und laufend entsprechend der fortschreitenden Füllung hochgezogenen Schlauchs mit Gießbeton gefüllt.When working with the formwork, the shell, which is open at the top, is used a hoist brought into the water down to the bottom. Then the sleeve is means one introduced and continuously raised according to the progressive filling Hose filled with cast concrete.
Gegenüber den bisher bekannten schlauchförmigen Hüllen ergibt sich also bei der Schalung nach der Erfindung der Vorteil, daß mehr oder weniger senkrechte Betonwände in jeder Form hergestellt werden können, die bisher nur mit festen Schalungen, beispielsweise Spundwänden usw., zu erstellen waren. Im Vergleich zu diesen starren Schalungen können die Hüllen in einer Fabrikationsstätte mit geringen Kosten in jeder gewünschten Form vorgefertigt und dann zusammengelegt bequem zur Baustelle transportiert werden.Compared to the previously known tubular casings, this results So with the formwork according to the invention the advantage that more or less vertical Concrete walls can be produced in any shape that was previously only possible with fixed formwork, for example sheet pile walls etc. were to be created. Compared to this rigid Formwork can be used in a manufacturing facility at a low cost in the casings prefabricated in any desired shape and then conveniently folded up to the construction site be transported.
Die Zeichnung veranschaulicht zwei Ausführungsbeispiele der Erfindung. Es zeigt Fig. 1 einen senkrechten Schnitt durch einen teilweise fertiggestellten zylindrischen Baukörper, Fig. 2 einen Querschnitt zu Fig. 1, Fig. 3 eine aus mehreren Hüllen zusammengesetzte Schalung in perspektivischer Ansicht.The drawing illustrates two exemplary embodiments of the invention. It shows Fig. 1 a vertical section through a partially completed cylindrical structure, FIG. 2 shows a cross section to FIG. 1, FIG. 3 shows one of several Envelopes composite formwork in perspective view.
Die Hülle 1 hat eine Außen- und eine Innenhaut aus einer oder mehreren Kunststoffolien od. dgl., die konzentrisch zueinander liegen, und ist mittels eines Halterahmens 2, der an ihrem oberen Rand angebracht ist, am Lasthaken 3 eines Krans (nicht dargestellt) aufgehängt. Zu Beginn der Arbeiten wird die Hülle, deren Länge entsprechend bemessen wurde, bis auf den Grund 4 eingebracht, wobei der obere Rand etwas über den Wasserspiegel 5 hinausragt.The shell 1 has an outer and an inner skin made of one or more Plastic films or the like, which are concentric to one another, and is by means of a Holding frame 2, which is attached to its upper edge, on the load hook 3 of a crane (not shown) hung. At the beginning of the work, the shell, its length was dimensioned accordingly, brought down to the bottom 4, with the upper edge slightly protrudes above the water level 5.
Zur Verstärkung hat die Hülle 1 Fäden, Schnüre oder Bänder aus Kunststoff od. dgl., die gegebenenfalls, in Netzform vorgesehen sind, indem beispielsweise die Verstärkung zwischen wenigstens zwei Kunststoffolien liegt. Außerdem ist die Hülle 1 in bestimmten Abständen eingeschnürt, wie bei 6 in Fig. 2 angedeutet ist.For reinforcement, the cover 1 has threads, cords or ribbons made of plastic Od. Like. Which are optionally provided in network form by, for example the reinforcement lies between at least two plastic films. Besides, the Sheath 1 constricted at certain intervals, as indicated at 6 in FIG. 2.
Damit die Hülle gut nach unten absinkt, kann bereits anfänglich etwas Beton als Beschwerung eingefüllt werden.Something can already be done at the beginning so that the cover sinks down well Concrete can be filled as a weight.
In die Hülle 1 wird mittels schwerer Schläuche 7, 8 Gießbeton eingefüllt. Diese Schläuche 7, 8 werden entsprechend der fortschreitenden Füllung hochgezogen, wie in Fig. 1 durch die verschieden hoch eingezeichneten Schläuche veranschaulicht ist.Cast concrete is poured into the shell 1 by means of heavy hoses 7, 8. These tubes 7, 8 are pulled up according to the progressive filling, how is illustrated in Fig. 1 by the hoses drawn in at different heights.
Unter Umständen kann das Einfüllen des Betons auch ohne Schläuche in vorsichtiger Form erfolgen, besonders wenn es sich nicht um große Tiefen handelt. Selbstverständlich kann der Beton auch armiert werden.Under certain circumstances, the filling of the concrete can also be carried out without hoses done with caution, especially if it is not about great depths. Of course, the concrete can also be reinforced.
Nach der Fertigstellung des Baukörpers kann dieser durch Spülen oder Absaugen des Untergrunds fundiert werden.After completion of the structure, it can be flushed or Vacuuming the subsurface.
Bei der Ausführung nach Fig.3 sind mehrere rohrförmige, unten geschlossene Hüllen 9 aneinanderliegend verbunden, beispielsweise durch Kleben, Schweißen usw. Diese Hüllen 9 haben zunächst einen runden Querschnitt und werden beim Zusammenfügen so verformt, daß sie einen etwa rechteckigen bzw. quadratischen Querschnitt haben, so daß die Schalung als Ganzes zum Errichten einer Mauer dienen kann. Die Innenräume der Hüllen 9 stehen durch Öffnungen 10 miteinander in Verbindung. In diesem Fall hat die Hülle auch unten einen Halterahmen 11.In the embodiment according to Figure 3, several tubular, closed at the bottom Sheaths 9 connected to one another, for example by gluing, welding, etc. These sheaths 9 initially have a round cross-section and when they are joined together deformed so that they have an approximately rectangular or square cross-section, so that the formwork as a whole can be used to build a wall. The interiors of the shells 9 are in communication with one another through openings 10. In this case the case also has a holding frame 11 at the bottom.
Zum Herstellen einer Mauer ist es auch möglich, anstatt der rohrförmigen Hüllen 9 zwei in entsprechendem Abstand liegende Schürzen aus Kunststofffolie vorzusehen, die an den Stirnenden und unten geschlossen sind. Zwischen den beiden Folienwänden sind in Schlaufen eingehängte Abstandhalter vorgesehen, die sinngemäß den Einschnürungen 6 nach Fig. 2 entsprechen. Beim Einfüllen des Gießbetons ergeben sich ebenfalls geringe Auswölbungen wie nach Fig. 2.To make a wall it is also possible instead of the tubular one Provide covers 9 with two suitably spaced aprons made of plastic film, which are closed at the front ends and at the bottom. Between the two foil walls spacers hung in loops are provided, which correspond to the constrictions 6 according to FIG. 2 correspond. When pouring the poured concrete, there are also small bulges as in Fig. 2.
Statt der verwendeten Kunststoffolien können auch dünne Bahnen aus Kautschuk verwendet werden, die in der bekannten Weise durch Einlagen dehnungsfest gemacht sind.Instead of the plastic sheeting used, thin sheets can also be used Rubber can be used, which is stretch-resistant in the known manner by means of inserts are made.
