Description

Vorrichtung zum nachträglichen Stabilisieren von wasserdurchlässigen  Device for the subsequent stabilization of water-permeable
Fugenkammerrissen in Brücken, Tunneln und Gebäuden Joint cracks in bridges, tunnels and buildings
Die Erfindung betrifft ein Vorrichtung eines Fugenkammer-Injektions-Systems gemäß dem Oberbegriff des Anspruchs 1 sowie ein entsprechendes Verfahren zur nachträg- liehen Stabilisierung von wasserdurchlässigen Fugenkammerrissen in Brücken, Tunneln und Gebäuden gemäß dem Oberbegriff des Anspruchs 15. The invention relates to a device of a joint-injection system according to the preamble of claim 1 and a corresponding method for subsequent lent stabilization of water-permeable joint chamber cracks in bridges, tunnels and buildings according to the preamble of claim 15th
Ein solches Fugenkammer-Injektions-System zum nachträglichen Stabilisieren eines Grenzbereichs zwischen Bauelementen, insbesondere einer wasserdurchlässigen Fugenkammer oder eines wasserdurchlässigen Betonübergangs, weist mindestens einen volumenveränderlichen Formkörper, insbesondere ein Fugenkammer- Abdichtkissen (3), welches mit einem veränderbaren Volumen gebildet ist, auf, wobei der Formkörper zumindest teilweise entlang des zu stabilisierenden Grenzbereichs vorsehbar ist. Das Unterqueren von WIB-Brücken und Tunneln mit Montagedecken ist im höchsten Maße bei Temperaturen ab 0° C und darunter bei Betonrissen quer zur Fugenkammer, durch Eiszapfen- und Glatteisbildung gefährdet. Langfristig ist auch die Bau- Substanz einsturzgefährdet, denn die Montagedecken bestehen im Prinzip aus lose zueinander angeordneten Längsträgern, welche in einem bestimmten Abstand zueinander parallel verlegt sind und die auf den raumabgrenzenden Gebäudestirnwänden aufliegen. Dabei werden die Längsträger-Zwischenräume durch eingefügte, meist hohle Deckensteine ausgefüllt, so dass eine geschlossene Deckenfläche ent- steht. Durch Ausgießen mit Mörtel werden dann konstruktionsbedingte Unebenheiten ebenflächig ausgeglichen. Hierbei entstehen zwischen den einzelnen Montageelementen, wie den Längsträgern, den Deckensteinen, dem Ausgleichsmörtel und der unterstützenden Wand, nur eine durch Auflagekräfte bedingte Reibungsverbindung und bei manchen Ausführungsformen auch zwischen bestimmten Montageelemen- ten eine mechanische Verklammerung. Durch den Mörtel kommt es noch zu einer gewissen adhäsiven Verbindung. Solche Verbindungen genügen aber nur den normal anfallenden Angriffslasten und Kräften, d. h. rein statischen Kräften und sehr geringfügigen Schwingungen, wie diese bei den sog. Verkehrslasten auftreten, für die die Decke ausgelegt ist. Such joint chamber injection system for subsequent stabilization of a boundary region between components, in particular a water-permeable joint chamber or a water-permeable concrete transition, at least one variable-volume molded body, in particular a joint chamber Abdichtkissen (3), which is formed with a variable volume, on the shaped body can be provided at least partially along the border region to be stabilized. Undercrossing of WIB bridges and tunnels with mounting ceilings is highly endangered at temperatures above 0 ° C and below with concrete cracks across the joint chamber, icing and ice formation. In the long term, the construction substance collapse, because the mounting ceilings consist in principle of loosely arranged side rails, which are laid parallel to each other at a certain distance and rest on the raumabgrenzenden building end walls. The longitudinal beam spaces are filled in by inserted, mostly hollow ceiling stones, so that a closed ceiling surface is created. By pouring with mortar then construction-related unevenness be leveled evenly. Here arise between the individual mounting elements, such as the side rails, the ceiling stones, the leveling mortar and the supporting wall, only a frictional connection caused by contact forces and in some embodiments, between certain Montageelemen- th a mechanical clamping. Through the mortar it still comes to a certain adhesive connection.

Eine Dichtung dieser Art ist aus dem DE-GM 84 25 518 bekannt. Sie ist als Injektionsschlauch ausgebildet. Der aus Gummi oder Kunststoff gefertigte Schlauch besitzt eine flüssigkeitsdurchlässige Wandung. Diese Wandung weist einen sich über ihre Länge erstreckenden Schlitz für den Austritt einer Injektionsflüssigkeit auf. In der Wandung ist im Bereich des Schlitzes eine sich ebenfalls über ihre Länge erstreckende Vertiefung für die Aufnahme eines den Schlitz überdeckenden Streifens vorgesehen, der aus einem sich unter dem Druck der Injektionsflüssigkeit volumenverändernden Material besteht. Die Wandung mit den Streifen ist von einem Schlauch aus flüssigkeitsdurchlässigem Material umschlossen. Dieser Injektionsschlauch be- steht somit aus drei zusammengefügten Teilen, die ein langgestrecktes flexibles Gebilde darstellen. Der erwähnte Streifen aus kompressiblem Material ist aus Moosgummi gefertigt. A seal of this type is known from DE-GM 84 25 518. It is designed as an injection hose. Made of rubber or plastic hose has a liquid-permeable wall. This wall has a slot extending over its length for the exit of an injection liquid. In the wall in the region of the slot is also provided over its length extending recess for receiving a slot covering the strip, which consists of a volume-changing material under the pressure of the injection liquid. The wall with the strips is enclosed by a tube of liquid-permeable material. This injection hose thus consists of three joined parts, which form an elongated flexible structure. The aforementioned strip of compressible material is made of sponge rubber.

Soll beispielsweise auf einer Betondecke eine Betonmauer errichtet werden, so wird ein Schlauch der vorstehend erwähnten Art auf die Betonplatte gelegt und hier fixiert, und zwar innerhalb jenes Bereiches, der von der Schalung für die zu errichtende Mauer begrenzt ist. Die beiden Enden des Schlauches werden nach außen geführt. Ist der Beton für die Mauer in die Schalung eingebracht und ist er in der Folge ausgehärtet, so wird in den Schlauch eine Injektionsflüssigkeit eingepresst, die die zwischen Plat- te und Mauer befindlichen Fugen dichtend füllt. Alle diese Dichtungen sind relativ aufwendig gebaut. Comparable constructions show and describe the following documents: DE-GM 91 11 114, DE-GM 83 00 766, DE-OS 33 20 875, DE-OS 34 00 654, DE-OS 35 12 470, DE-OS 41 23 067, DE-OS 41 24 628, EU-PS 199 108, DE 41 04 402 A1, CH 462 420 A, DE 34 27 110 A1, DE 43 40 845 A1 and EU-OS 501 004. If, for example, a concrete wall to be built on a concrete surface Thus, a hose of the type mentioned above is placed on the concrete slab and fixed here, within that range, which is bounded by the formwork for the wall to be built. The two ends of the hose are led to the outside. If the concrete for the wall has been inserted into the formwork and if it has subsequently hardened, then an injection liquid is injected into the hose, which injects the fluid between sealing and filling the wall. All these seals are built relatively expensive.
Bekannt sind ferner Dichtungsmaterialien aus Kunststoffmassen (DE-OS 42 26 198 und DE-OS 42 26 385), die beim Kontakt mit Wasser aufquellen und die zur Fugenabdichtung oder auch zum Ausgleich von Dimensionsänderungen im Hoch-, Tiefund Ingenieurbau oder in anderen technischen Bereichen eingesetzt werden. Aus diesem Material werden Streifen mit beispielsweise rechteckigem Querschnitt gefertigt. Bei der Errichtung eines Mauerwerkes, wie vorstehend beschrieben, werden sol- che Streifen auf die Betonplatte aufgelegt und fixiert, und zwar innerhalb der Schalung, die für die zu errichtende Mauer dient. Wird ein solcher Dichtstreifen eventuell bei regennassem Wetter verlegt, so quillt er auf, bevor der Beton für die Mauer in die Schalung eingebracht werden kann. Erreicht er dabei sein maximales Volumen, so ist seine Dichtfähigkeit in der Folge in Frage gestellt. Diese Dichtung ist nach Fertig- Stellung der Mauer nicht mehr zugänglich. Also known are sealing materials made of plastic materials (DE-OS 42 26 198 and DE-OS 42 26 385), which swell on contact with water and used for joint sealing or to compensate for dimensional changes in construction, civil engineering and other technical fields become. From this material strips are made, for example, rectangular cross-section. In the construction of a masonry, as described above, such strips are placed on the concrete slab and fixed, within the formwork, which serves for the wall to be built. If such a sealing strip is laid in rainy weather, it will swell up before the concrete for the wall can be inserted into the formwork. If it reaches its maximum volume, then its sealing ability is questioned in the sequence. This seal is no longer accessible after completion of the wall.
Der Vollständigkeit halber sei auch noch die Dichtung zum Abdichten von gegeneinander gepressten Stirnwänden von Betonfertigteilen nach der DE-OS 35 09 845 erwähnt. Das hier verwendete Gummiprofil hat einen dreieck- oder kreissegmentför- migen Querschnitt. Damit sollen Spalten zwischen Betonfertigteilen abgedichtet werden, die 30 bis 90 % der Höhe des Gummiprofiles aufweisen. Die CH-PS 542 965 beschreibt ein Dichtungsprofil aus einem elastischen Profilteil und einem den elastischen Profilteil zeitweise vorgespannt haltenden starren Profilteil, der mit der Schalung zu verbinden ist. Nach dem Einbringen und nach dem Aushärten des Betons wird die Schalung mit dem daran befestigten starren Profilteil entfernt, wodurch sich der elastische Profilteil entspannen kann. Dichtungen dieser Art sind für den Einsatz bei Arbeitsfugen nicht zweckmäßig und auch nicht geeignet. Die Aufgabe der Erfindung besteht darin, eine wiederverwendbare quellvliesbe- schichtete Schutzvorrichtung gegen Wasserfortleitung mit einem wirtschaftlichen Fu- genkammer-/Beton-Riss-lnjektions-System gemäß der im Oberbegriff des Anspruchs 1 genannten Art zu schaffen. For the sake of completeness, the seal for sealing pressed against each other end walls of precast concrete parts according to DE-OS 35 09 845 may be mentioned. The rubber profile used here has a triangular or circular cross-section. This should be sealed columns between precast concrete, which have 30 to 90% of the height of the rubber profile. The CH-PS 542 965 describes a sealing profile of an elastic profile part and the elastic profile part temporarily biased holding rigid profile part, which is to be connected to the formwork. After insertion and after curing of the concrete, the formwork is removed with the attached rigid profile part, whereby the elastic profile part can relax. Seals of this type are not suitable for use in construction joints and also not suitable. The object of the invention is to provide a reusable, nonwoven-coated protective device against water transmission with an economical joint chamber / concrete crack injection system according to the type mentioned in the preamble of claim 1.

Eine zweckmäßige Weiterbildung der Erfindung sieht vor, dass das stabförmige Führungselement als Glasfaserverbundstab mit einem Mindestdurchmesser von 3 mm und/oder mit einer mindestens 0,5 mm dicken Kunststoffumhüllung ausgebildet ist. Die abdichtende Wirkung wird durch mindestens drei Funktionen erreicht: An expedient development of the invention provides that the rod-shaped guide element is designed as a glass fiber composite rod with a minimum diameter of 3 mm and / or with a plastic sheath at least 0.5 mm thick. The sealing effect is achieved by at least three functions:
Die erste abdichtende Funktion weist ein Abdichtkissen mit Ventil auf, welches unter Druck das Quellvliesdichtband und/oder Abdichtsterne in die Zwischenräume presst.  The first sealing function has a sealing pad with valve which presses the swellable nonwoven sealing tape and / or sealing stars into the interstices under pressure.
Die zweite abdichtende Funktion kommt erst zum Tragen, wenn Wasser oder Che- mikaliengemische phte, pHi2 und/oder ca. 80 % Benzin, Diesel, Kerosin oder Paraf- finölgemisch das Quellvlies aktivieren. Bei Wassereintritt quillt das im PP-Vlies eingebettete Polymer an den nicht verpressten Abdichtstellen auf und schafft durch seine extrem dichte, gelförmige, in das PP-Vlies eingebettete Dichtschicht den Schutz gegen Wasserfortleitung während des Wassereintrittes. Nach Trocknung der Gelschicht kann ein Überdruck bei Wärme von 0,3 bar durch das Quellvlies entweichen, bei neuem Wassereintritt quillt das Polymer wieder zuverlässig auf. Die dritte abdichtende Funktion kommt dann zum Tragen, wenn das im Oberbegriff des Anspruches 1 genannte Fugen-Injektions-Mikrokabelrohr und das Zubehör installiert und die Fugenkammer-/Betonrisse mit Injektionsmittel zuverlässig abgedichtet sind. Die Vorrichtung zum nachträglichen Stabilisieren von wasserdurchlässigen Fugen mit Betonabdeckungen mit Wechselwirkung in Gewerken soll universell für ein breites Anwendungsspektrum geeignet sein und mittels hoher Kerbzäh-, Berstdruck-, Chemikalien- und Wasserdruckbeständigkeit mit einem geringen Eigengewicht ab 850 g/m2 die Anforderung erfüllen, mechanisch einen wirksamen elastischen Flä- chenanpress- und/oder Wassersperrdruck aufzubringen. The second sealing function only becomes effective when water or chemical mixtures pht, pHi2 and / or approx. 80% gasoline, diesel, kerosene or paraffin oil mixture activate the swellable nonwoven. When water enters, the polymer embedded in the PP fleece swells up at the non-compressed sealing points and provides protection through its extremely dense, gel-like sealing layer embedded in the PP fleece against water leakage during water ingress. After drying the gel layer, an overpressure at a heat of 0.3 bar can escape through the swellable nonwoven, with new water ingress, the polymer swells reliably again. The third sealing function comes into play when the mentioned in the preamble of claim 1 joint injection microcable and the accessories installed and the Fugenkammer- / concrete cracks are reliably sealed with injection means. The device for the subsequent stabilization of water-permeable joints with concrete covers with interaction in trades should be universally suitable for a wide range of applications and by means of high notch, bursting pressure, chemical and water pressure resistance with a low weight from 850 g / m 2 meet the requirement, mechanically to apply an effective elastic surface pressure and / or water barrier pressure.
Des Weiteren sollen in der ersten Funktion mit der aufblasbaren, von außen quell- vliesbeschichteten bis 50 m langen Vorrichtung Dehnfugen in Breiten von 2 cm bis 40 cm in einer Rekordzeit von etwa 10 min/m und in der zweiten Funktion mit der Vergelung von einer gut zugänglichen Stelle aus ohne Injektionsbohrungen (Bauwerkschädigungen), ohne besondere langzeitige Verkehrswegesperrung und ohne Verunreinigung zuverlässig und wirtschaftlich abgedichtet werden. Furthermore, in the first function with the inflatable device, which is externally swell-coated up to 50 m long, expansion joints in widths of 2 cm to 40 cm should be achieved in a record time of about 10 min / m and in the second function with gelling of one accessible location without injection wells (structural damage), without special long-term road closure and without contamination are reliably and economically sealed.
In der dritten Funktion sollen temporär Personen und Sachschäden durch Wasser- durchdringung und Fortleitung mit Folgen von Eiszapfenbildung und Glättebildung an der Bausubstanz zuverlässig vermieden werden. Die bekanntesten Dehnfugenabdichtsysteme, nämiich In the third function, persons and damage to property due to water penetration and passage with consequences of icicle formation and smoothness formation on the building structure are to be avoided temporarily. The most well-known expansion joint sealing systems, namely
Fugenbänder aus Gummi oder Bitumen,  Joint tapes made of rubber or bitumen,
Fugenbleche,  Seam joints,
quellfähige Fugeneinlagen aus Gummi,  swellable joint inlays made of rubber,
- Injektionsschlauch,  - injection hose,
Injektionsverpressungen,  Injektionsverpressungen,
PUR-Gel Injektionsverpressungen  PUR gel injection grouting
haben die bekannten Nachteile, dass die Abdichtungen unter Betriebsbedingungen, wie Setzungen, Scherungen und Dehnungen, im Temperaturbereich von -30° C bis +60° C unbeständig sind. have the known disadvantages that the seals under operating conditions, such as subsidence, shearing and stretching, in the temperature range from -30 ° C to + 60 ° C are unstable.
Ein weiterer Nachteil bei den Injektionsverpressungen ist ein sehr hoher Arbeitsaufwand für Injektionsbohrungen, die vor der Injektionsverpressung angebracht werden müssen, wodurch die Wirtschaftlichkeit des Systems sehr beeinträchtigt wird. Another disadvantage of injection grouting is a very high workload for injection wells that must be installed prior to injection grouting, which greatly affects the economics of the system.
Die vorteilhaften, endgültigen, dem jeweiligen Anwendungsbereich entsprechenden Modifikationen des vorgenannten Grundbauteils zeigen die nachfolgenden Beschreibungen. Bei Verwendung als Wassersperrschutzvorrichtung zum wasserdichten Verschließen von Dehnfugen und/oder Bewegungsfugen ist das mit Luft befüllbare Abdichtsystem vorzugsweise vollflächig mit einem wasserquellenden Quellvlies-Dichtband umschlossen, um eine völlige Wassersperre zu den Fugenflanken zu erzielen. Das Flachschlauchkissen wird für eine gleichmäßige und/oder wechselnde Fugenbreite je nach Typ, zum Beispiel 2 cm bis 8 cm, 2 cm bis 17 cm oder 2 cm bis 300 cm, längsförmig über Fugenversatzsteilen, Bögen und/oder Ecken gelegt und bis zur Druckfüllung mit PE- (oder gleichwertigen) Rundschnurabschnitten gesichert. Die Befüllung des Flachschlauchkissens erfolgt über ein metallenes Ventil, welches mit einer in das Flachschlauchkissen eingeschweißten Verlängerung verbunden ist. Beim Aufpumpen des Flachschlauchkissens mit Luft werden die Quellvliesdichtbän- der in die Zwischenräume von Fugenkammern gepresst. The advantageous, final, the respective field of application corresponding modifications of the aforementioned basic component show the following descriptions. When used as a water-barrier device for watertight sealing of expansion joints and / or expansion joints, the air-sealable sealing system is preferably fully enclosed with a water-swelling swell-sealing tape to achieve a complete water barrier to the joint flanks. Depending on the type, for example 2 cm to 8 cm, 2 cm to 17 cm or 2 cm to 300 cm, the flat-tube cushion is laid longitudinally over joint offset parts, bends and / or corners for a uniform and / or varying joint width until it is filled with pressure PE (or equivalent) round cord sections secured. The filling of the flat tube pad via a metal valve, which is connected to a welded-in the flat tube cushion extension. When inflating the flat hose cushion with air, the swelling fleece sealing tapes are pressed into the interstices of joint chambers.
Die Demontage der wiederverwendbaren Vorrichtungen ist durch Evakuierung mittels Vakuumpumpe oder Ausbauen des Ventileinsatzes einfach möglich. Zum Abdichten von Fugen in Längen von bis zu 23 m und mehr werden ein zweites und weitere Abdichtkissen zu etwa 0,25 m bis 1 m mit dem ersten Abdichtkissen überlappend in die Fuge eingelegt, so dass Dichtigkeit an der Überlappung erzielt wird. Die Füllung der Flachschlauchkissen ist möglich, indem zuerst das längste Abdichtkissen und anschließend das kürzeste Abdichtkissen bis zum Soll-Fülldruck befüllt werden. The disassembly of the reusable devices is easily possible by evacuation by vacuum pump or removing the valve core. For sealing joints in lengths of up to 23 m and more, a second and further sealing pad to about 0.25 m to 1 m with the first sealing pad overlapping inserted into the joint, so that tightness is achieved at the overlap. The filling of the flat hose cushions is possible by first filling the longest sealing pad and then the shortest sealing pad to the desired filling pressure.
Zum Abdichten von Fugen in Bogenbrücken werden Abdichtkissen in Längen des Bogenradius eingesetzt. Alle Abdichtkissen werden jeweils an den Enden deckungsgleich und etwa 0,25 m überlappend in die Fugen eingelegt und mit einer PE- Rundschnur bis zur Druckfüllung gesichert. For sealing joints in arch bridges, sealing cushions are used in lengths of the radius of curvature. All sealing cushions are inserted into the joints at the ends in a congruent manner and overlapping approximately 0.25 m and secured with a PE round cord until pressure is filled.
