Gebrauchsmusteranme!dung:Utility model application:

Betrifft: Blähdichtung für Steinzeugrohre, Subject: inflatable seal for clay pipes,

Die Erfindung bezieht sich auf eine Blähdichtung für Kanalisationsrohre von gleichbleibendem Profil.The invention relates to an inflatable seal for sewer pipes of constant profile.

Solche Rohre werden in der Regel als Muffenrohre, d. h. mit angepresster Muffe, hergestellt. Diese Rohre sind aber schwierig abzudichten, da in der Baugrube wegen der geringen Ausmaße der Baugrube wohl meistens noch Wasser fließt. Zur Dichtung werden die Rohre ineinandergeschoben und von der Seite her die Abdichtung vorgenommen.Such pipes are usually called socket pipes, i.e. H. with pressed-on socket. However, these pipes are difficult to seal because in the construction pit because of the small dimensions of the Most of the time, water still flows in the excavation pit. The pipes are pushed into one another to seal and made the seal from the side.

Es ist aber auch bekannt, Rohre gleichen Durchmessers mit Dichtmanschetten, die durch Spannelemente über den Rohrstoß angepresst werden, zu dichten.But it is also known to have pipes of the same diameter with sealing collars, which are secured by clamping elements are pressed over the pipe joint to seal.

Diese Dichtungen erfordern Spannelemente aus Metall, die der Korrosion ausgesetzt sind, oder bei korrosionsfestem Material erhebliche Kosten verursachen.These seals require clamping elements made of metal, which are exposed to corrosion, or cause considerable costs in the case of corrosion-resistant material.

Außerdem können mit diesen Elementen die Dichtflächen bei den verschiedenartig deformierten Rohren nicht ausreichend angepresst werden.In addition, these elements can be used to seal the sealing surfaces of the variously deformed pipes are not pressed sufficiently.

Uli ,:Uli,:

Durch das Blähdichtsystem wird der Dichtring in jedem Teil seiner Dichtfläche an das Rohr auch dann präzise angepresst, wenn dieses Rohr deformiert ist. Außerdem kann der Widerlagerring der Dichtmuffe aus einfachen Baustoffen, z. B. aus Beton, aus Steinsug oder bei kleineren Dimensionen aus Kunststoff bestehen und ist darum unbegrenzt haltbar.The sealing ring in each Part of its sealing surface is precisely pressed against the pipe even if this pipe is deformed. In addition, the abutment ring of the sealing sleeve can be made of simple building materials such. B. from concrete, from stone suction or made of plastic in the case of smaller dimensions and is therefore indefinitely durable.

In dem Widerlagerring 1 ist der blähbare Dichtring 2 so gelagert, daß sich ein achlauchartiger Raum bildet, in den eine Füllmasse durch den Füllstutzen 3 eingepresst wird. Dadurch wird der Dichtring aufgebläht und an die Rohrwandung zur Dichtung angepresst.In the abutment ring 1, the inflatable sealing ring 2 is mounted so that a tube-like Forms space into which a filling compound is pressed through the filling nozzle 3. This will make the sealing ring inflated and pressed against the pipe wall to seal.

Der vorgefertigte Dichtring wird zur Dichtung in der Baugrube lediglich über die Stoßstelle der Rohre geschoben und die Füllmasse mittels Pumpe eingepresst. The prefabricated sealing ring only acts as a seal in the construction pit over the joint between the pipes pushed and the filling compound pressed in by means of a pump.

Die Blähdichtung besteht aus säure- und korrosionsfestem Material und ist unbegrenzt haltbar.The inflatable seal is made of acid and corrosion resistant Material and is indefinitely durable.

Sie ist auch in geringem Umfang elastisch, sodaß bei eintretender Veränderung des Bodens nach der Verlegung der Rohrstrang nicht gefährdet ist.It is also elastic to a small extent, so that when the soil changes after the Laying the pipe string is not endangered.

In der beiliegenden Zeichnung ist die Blähdichtung nach der ErfindungIn the accompanying drawing is the inflatable seal according to the invention

a) im verlegten Zustanda) when installed

b) vor der Verlegung dargestellt.b) shown before installation.

Die Dichtung besteht aus dem Widerlagerring 1 mit Einfüllstutzen 33 der mit einem Rückschlagventil ausgestattet ist.The seal consists of the abutment ring 1 with filler neck 3 3 which is equipped with a check valve.

In dem Widerlagerring ist der Dichtring 2 eingelegt, der an den Außenseiten an dem Widerlagerring abdichtet. Diese Abdichtung kann je nach Ausführung des Widerlagerringes unterschiedlich sein.In the abutment ring, the sealing ring 2 is inserted, which seals on the outside of the abutment ring. This seal can be different depending on the design of the abutment ring.

Es ist zweckmäßig, auf die Innenseite des Dichtringes eine langsam härtende zähharte Dichtmasse aufzustreichen, die sich bei dem Dichtvorgang durch Aufblähen des Dichtringes in eventuell vorhandene Poren, kleine Deformierungen und in den Stoß einpresst und die Dichtwirkung erhöht.It is advisable to use a slowly hardening, tough and tough sealing compound on the inside of the sealing ring to spread, which during the sealing process by expanding the sealing ring in any existing Pores, small deformations and presses into the joint and increases the sealing effect.
