Abstract

In an amendment to Patent Application P 3430789.3, it is proposed to use the connection of diaphragms as a seal between two precast trench-wall members. To this end, the outer slit connecting tube is anchored in a front end of a precast trench-wall member. The inner slit connecting tube is bonded in place with a sealing strap in the front end of the adjoining precast trench-wall member. The connecting tubes are preferably to be connected to one another homogeneously by welding after the fitting of the connection.

Description

Vorrichtung zum Abdichten von FertigteilschlitzwändenDevice for sealing prefabricated diaphragm walls

Das Hauptpatent bezieht sich auf ein Verfahren und eine Vorrichtung zum Einbringen und Verbinden von Membranen in Schlitzwänden. An den senkrechten Membranberandungen sind durchgehend geschlitzte Rohre als Verbindungselemente angebracht, die beim Einbringen benachbarter Membrane ineinandergeschoben werden. Zur Verbindung der Rohre untereinander werden unterschiedliche Möglichkeiten aufgezeigt, wie z. B. das Verschweissen der Kontaktflächen mit einem Schweißgerät, mit Glimmschnüren oder wie in der Zusatzanmeldung P 35 03 542.0 dargestellt, durch elektrisch aufheizbare Drähte.The main patent relates to a method and an apparatus for inserting and connecting membranes in diaphragm walls. On the vertical Membrane borders are fitted with continuously slotted tubes as connecting elements, which are pushed into one another when inserting neighboring membranes. To connect the pipes with each other are shown different possibilities, such. B. the welding of the contact surfaces with a welding device, with glow cords or as shown in the additional application P 35 03 542.0, by electrically heated Wires.

Eine vorteilhafte Erweiterung findet das Verfahren und die Vorrichtung bei der Anwendung zum Abdichten von Fertigteil-Schlitzwandabschnitten untereinander. Hierzu sind bisher lediglich Methoden bekannt, die Kontaktflächen von Steckverbindungen mechanisch geg eneinanderdrücken, die aber keine homogene Verbindung, z. B. durch Verschweißen der Steckelemente untereinander erlauben. Die erfindungsgemäße Vorrichtung nach dem Oberbegriff des Anspruches 1 löst diese Aufgabe durch Einbau von ineinandersteckbaren geschlitzten Rohren, vorzugsweise aus HUPE, die nach Ausräumen des Innenraumes 11 miteinander verschweißt werden können. An Stelle der Membrane verfügt das äussere geschlitzte Verbindungsrohr 4 über Anker 7 mit denen das Verbindungsrohr 4 bündig in die eine Stirnseite 12.1 des Schlitzwandfertigteiles 3 einbetoniert wird. Am inneren geschlitzten Verbindungsrohr 8 ist an Stelle der Membran eine Dichtlasche 9 angeschweißt, die über Ankerbänder 10 verfügt. Diese Dichtlasche 9 wird in die andere Stirnseite 12.2 des Schlitzwandfertigteiles 3 bei der Herstellung desselben einbetoniert.The method and the device are an advantageous extension when used for sealing prefabricated diaphragm wall sections with one another. For this purpose, only methods are known so far, the contact surfaces of plug connections mechanically press against each other, but the connection is not a homogeneous one, e.g. B. by Allow the plug-in elements to be welded together. The device according to the invention according to the preamble of claim 1 solves this problem by installing nested slotted pipes, preferably made of HUPE, which after clearing the interior 11 can be welded together. Instead of the membrane, the outer slotted connecting pipe 4 via anchor 7 with which the connecting pipe 4 is flush in which one end face 12.1 of the prefabricated diaphragm wall part 3 is concreted. At the inner slotted connecting tube 8 is a sealing tab instead of the membrane 9 welded on, which has anchor straps 10. This sealing tab 9 is in the other End face 12.2 of the diaphragm wall prefabricated part 3 concreted in during the manufacture of the same.

Weitere Merkmale ergeben sich aus den Ansprüchen und der weiteren Beschreibung.Further features emerge from the claims and the others Description.

Die Erfindung wird anhand zweier,in den Fig. 1 und 2 dargestellten, Ausführungsbeispielen näher erläutert.The invention is based on two, shown in Figs. 1 and 2, Embodiments explained in more detail.

Es zeigen in schematischer Darstellung: Fig. 1: einen Querschnitt durch eine Fertigteilschlitzwand Fig. 2: einen Detailquerschnitt der erfindungsgemäßen Vorrichtung Fig. 1 zeigt die innerhalb der Schlitzwandberandungen 1.1 und 1.2 eingestellte Schlitzwandfertigteile 3, die abschnittsweise in die Stützsuspension 2 eingestellt werden. An den Stirnseiten 12 der Fertigteilabschnitte 3 sind die erfindungsgemäßen Vorrichtungen zur Herstellung einer durchgehend dichten Verbindung der Fertigteilwandabschnitte 3 untereinander in die Schlitzwandfertigteile 3 eingebaut. Die Vorrichtung besteht aus einem einbetonierten aussehen geschlitzten Verbindungsrohr 4, welches mit Ankern 7 im Beton festgehalten ist und aus einem inneren geschlitzten Verbindungsrohr 8, das mit einer Dichtlasche 5 und Ankerbändern 10 im benachbarten Stirnseitenbereich 12 im Beton des Schlitzwandabschnittes 3 verankert ist.They show in a schematic representation: FIG. 1: a cross section through a prefabricated diaphragm wall. FIG. 2: a detailed cross section of the inventive Device Fig. 1 shows the set within the trench wall boundaries 1.1 and 1.2 Precast diaphragm wall parts 3, which are set in sections in the supporting suspension 2 will. On the end faces 12 of the prefabricated sections 3 are those according to the invention Devices for producing a continuously tight connection between the prefabricated wall sections 3 built into the prefabricated diaphragm wall parts 3 one below the other. The device consists from a concreted-in look slotted connecting pipe 4, which with anchors 7 is held in the concrete and consists of an inner slotted connecting pipe 8, that with a sealing tab 5 and anchor straps 10 in the adjacent end face area 12 is anchored in the concrete of the diaphragm wall section 3.

Die Herstellung der Schweißverbindung 13 an den Kontaktflächen 38 und 39, wie in Fig. 2 dargestellt, erfolgt nach Freispülen des Innenraumes 11 mit Hilfe einer im Innenraum verfahrbaren Schweißvorrichtung oder durch andere Verbindungselemente, wie im Hauptpatent P 34 30 789.3 bereits erläutert.The production of the welded connection 13 on the contact surfaces 38 and 39, as shown in FIG. 2, takes place after the interior 11 has been flushed free With the help of a welding device that can be moved in the interior or by other connecting elements, as already explained in the main patent P 34 30 789.3.

Mit der erfindungsgemässen Vorrichtung ist eine durchgehend dichte Schweißverbindung der Dichtungselemente zwischen den Fertigteilabschnitten 3 erstmals möglich. Damit sind dauerhaft dichte Fertigteilschlitzwände herstellbar.With the device according to the invention, a continuously sealed Welded connection of the sealing elements between the prefabricated sections 3 for the first time possible. In this way, permanently sealed pre-fab diaphragm walls can be produced.
