Description

Bei den gegenwärtigen Bauten werden normalerweise Massnahmen gegen die Bodenfeuchtigkeit ergriffen. Aufgrund fehlerhafter Ausführung der Arbeiten oder bei Altbauten kann jedoch diese Feuchtigkeit schwere Probleme verursachen, wobei die Behebung sehr kostspielig ist.Measures against soil moisture are usually taken in current buildings. However, due to incorrect execution of the work or in old buildings, this moisture can cause serious problems, which is very costly to remedy.

Um dieses Problem der Feuchtigkeit in den Wänden zu lösen, werden seit einiger Zeit Versuche gemacht, die Wände wasserabstossend zu machen.In order to solve this problem of moisture in the walls, attempts have been made for some time to make the walls water-repellent.

Die bekannte Methode, wasserabstossende Flüssigkeit in Bohrungen in der Mauer einzuspritzen, ergibt keine positiven Ergebnisse, weil die wasserabstossende Flüssigkeit in den Ritzen und in stärker porösen Zonen der Mauer verlorengeht und daher die anderen Mauerzonen ohne Schutz bleiben.The known method of injecting water-repellent liquid into boreholes in the wall does not give any positive results because the water-repellent liquid is lost in the cracks and in more porous zones of the wall and therefore the other wall zones remain without protection.

Als Stand der Technik sind ferner die in der GB-PS Nr. 1580701 und US-PS Nr. 2071758 beschriebenen Methoden zu nennen.The methods described in GB-PS No. 1580701 and US-PS No. 2071758 should also be mentioned as prior art.

Ferner ist in der DE-AS Nr. 1609395 und in der AT-PS Nr. 276702 eine Methode unter Verwendung eines Rohres mit Schaumbeschichtung beschrieben, das in die Mauerbohrungen eingeführt wird. Diese Methode erfordert jedoch viel Arbeit für die ständige Überwachung und Füllung einer grossen Vielzahl von Behältern und auch Fachpersonal zur Reinigung der Schaumbeschichtung und der Behälter; ferner geht auch ein Teil der wasserabstossenden Flüssigkeit in den Ritzen und in den stärker porösen Zonen verloren, denn die Flüssigkeitsmenge pro Zeiteinheit, die aus der Schaumbeschichtung austritt, hängt von der Porosität der Mauerzone ab, mit der diese Beschichtung in Berührung steht.Furthermore, DE-AS No. 1609395 and AT-PS No. 276702 describe a method using a tube with a foam coating which is inserted into the wall bores. However, this method requires a lot of work for the constant monitoring and filling of a large variety of containers and also specialist personnel for cleaning the foam coating and the containers; furthermore, part of the water-repellent liquid is lost in the cracks and in the more porous zones, because the amount of liquid per unit of time that emerges from the foam coating depends on the porosity of the wall zone with which this coating is in contact.

Ferner ist in der AT-PS Nr. 253178 eine Vorrichtung zur Isolierung von Mauern gegen aufsteigende und/oder seitlich eindringende Feuchtigkeit mit einem druckluftbetätigten Einspritzgerät zum Einbringen eines flüssigen Isolationsmittels in Sackbohrungen beschrieben, die in einem streifenförmigen Bereich der Mauer vorgesehen sind. Das flüssige Isolationsmittel weist eine hohe Viskosität auf und muss daher vorgewärmt und mit hohem Druck in die Mauer eingepresst werden. Zur Verankerung und Abdichtung des Einspritzkopfes in den Sackbohrungen der Mauer sind besondere Merkmale erforderlich. Eine genaue Dosierung des Isolationsmittels entsprechend der Porosität des Mauerwerks ist jedoch nicht vorgesehen und kann nicht durchgeführt werden. Die Vorrichtung ist zwar einfach in der Handhabung, erfordert jedoch eine ständige Überwachung.Furthermore, AT-PS No. 253178 describes a device for insulating walls against rising and / or laterally penetrating moisture with a compressed air-operated injection device for introducing a liquid insulation agent into blind holes which are provided in a strip-shaped area of the wall. The liquid insulation medium has a high viscosity and must therefore be preheated and pressed into the wall with high pressure. Special features are required to anchor and seal the injection head in the blind holes in the wall. However, an exact dosage of the insulation agent according to the porosity of the masonry is not provided and cannot be carried out. Although the device is easy to use, it requires constant monitoring.

Ferner sind in der DE-AS Nr. 1098451 eine Methode und eine Vorrichtung zum Verfestigen oder Abdichten von Bodenschichten beschrieben, wobei eine erhärtende Flüssigkeit unter sehr hohem Druck in das Erdreich eingepresst wird. Der nötige Einpressdruck wird dadurch erzielt, dass ausserhalb des Erdreiches Rammimpulse auf die Flüssigkeit im Einpressrohr und damit bis zu dessen Ende übertragen werden, wo die Flüssigkeit in das Erdreich austritt. Eine Regelung der Impulsstärke und/oder der Zeitintervalle zwischen den Impulsen zur Dosierung der Flüssigkeit ist jedoch nicht vorgesehen.Furthermore, DE-AS No. 1098451 describes a method and a device for solidifying or sealing soil layers, wherein a hardening liquid is pressed into the soil under very high pressure. The necessary injection pressure is achieved by the fact that ramming impulses are transmitted outside the soil to the liquid in the injection pipe and thus to the end where the liquid exits into the soil. However, regulation of the pulse strength and / or the time intervals between the pulses for metering the liquid is not provided.

Die Erfindung betrifft ein Verfahren zum Einführen von Flüssigkeit gegen die aufsteigende Feuchtigkeit im Mauerwerk, wobei die wasserabstossende oder hydrophobe Flüssigkeit der Mauer gleichmässig über perforierte Rohre mit einem Kompressor zugeführt wird und das Verfahren dadurch gekennzeichnet ist, dass die Flüssigkeit mittels regelmässiger Impulsezugeführt wird, die vom Kompressor und einer Dosierungseinrichtung ausgehen, welche durch eine elektronische, hydraulische oder pneumatische Einrichtung oder manuell gesteuert werden, wobei die Impulsstärke und die Zeitintervalle zwischen den einzelnen Impulsen zur Zufuhr der Flüssigkeit, die der Mauer zuzuführen ist, enstsprechend den am wenigsten porösen Zonen der Mauer variabel eingestellt oder geregelt werden können, und wobei je nach Art der Mauer die Dosiereinrichtung derart eingestellt wird, dass sie die Menge der wasserabstossenden oder hydrophoben Flüssigkeit pro Zeiteinheit abgibt, die der normalen Absorption der Mauer entspricht, und die die am wenigsten poröse Stelle der Mauer absorbieren kann. So wird keine wasserabstossende Flüssigkeit vergeudet.The invention relates to a method for introducing liquid against the rising moisture in the masonry, wherein the water-repellent or hydrophobic liquid is supplied to the wall uniformly via perforated pipes with a compressor and the method is characterized in that the liquid is supplied by means of regular impulses from the Compressor and a metering device, which are controlled by an electronic, hydraulic or pneumatic device or manually, the pulse strength and the time intervals between the individual pulses for supplying the liquid to be supplied to the wall, according to the least porous zones of the wall variable can be set or regulated, and depending on the type of wall, the metering device is set such that it delivers the amount of water-repellent or hydrophobic liquid per unit of time which corresponds to the normal absorption of the wall, and which can absorb the least porous part of the wall. So no water-repellent liquid is wasted.

Beim erfindungsgemässen Verfahren wird die Imprägnierungsflüssigkeit bzw. die wasserabweisende Flüssigkeit in an sich bekannter Weisedurch Rohre bis zu Sackbohrungen in der zu behandelnden Mauer geführt, worin die Flüssigkeit sich gleichmässig verteilt und die Mauermasse einheitlich imprägniert, wobei jedoch erfindungsgemäss die Menge der wasserabstossenden oder hydrophoben Flüssigkeit pro Zeiteinheit nur von der Dosierungseinrichtung und nicht von der Porosität der Mauer geregelt wird.In the method according to the invention, the impregnation liquid or the water-repellent liquid is passed in a manner known per se through pipes to blind bores in the wall to be treated, in which the liquid is uniformly distributed and the wall mass is impregnated uniformly, but according to the invention the amount of water-repellent or hydrophobic liquid per Time unit is regulated only by the metering device and not by the porosity of the wall.

Die Erfindung betrifft ferner eine Vorrichtung zur Durchführung des erfindungsgemässen Verfahrens, die durch eine Dosierungseinrichtung gekennzeichnet ist, die die Flüssigkeit durch programmierbare sowie regelbare Impulse und Pausen entsprechend der Porosität des Mauerwerks dosiert und zuführt, wobei die Impulse elektronisch, hydraulisch, pneumatisch oder manuell gesteuert werden.The invention further relates to a device for carrying out the method according to the invention, which is characterized by a dosing device which doses and supplies the liquid by means of programmable and controllable pulses and pauses in accordance with the porosity of the masonry, the pulses being controlled electronically, hydraulically, pneumatically or manually .

Durch das erfindungsgemässe Verfahren und die Vorrichtung zur Durchführung des erfindungsgemässen Verfahrens überwindet man alle Nachteile des Standes der Technik und erzielt die nachstehenden Vorteile:

  • - Da die Abgabe der Flüssigkeit unter Druck über einen Kompressor erfolgt, verhindert man die Verlegung der Durchtrittsöffnungen der in der Mauer versenkten perforierten Rohre, wie klein diese Durchtrittsöffnungen auch sein mögen.
  • - Die Menge der wasserabweisenden Flüssigkeit, die bei jedem Impuls in die Mauer eingeführt wird, und die Zeitintervalle zwischen den jeweiligen Impulsen kann man genau dosieren und entsprechend der Porosität der zu behandelnden Mauer einstellen.
  • - Beim erfindungsgemässen Verfahren ist weder eine Ablesung, Überwachung noch eine Füllung von einer Vielzahl von Behältern notwendig, wie sie bei den Methoden des Standes der Technik erforderlich waren.
  • - Man kann Mauern verschiedener Dicke behandeln, ohne dass man die Zufuhr der wasserabweisenden Flüssigkeit je nach Mauerdicke überwachen müsste, weil die Menge der zuzuführenden Flüssigkeit nur von der Anzahl der Durchtrittsöffnungen der in der Mauer versenkten perforierten Rohre abhängt; wenn man also beispielsweise eine Mauer von 20 cm Dicke mit einem Rohr mit 20 Durchtrittsöffnungen behandelt, behandelt man eine Mauer von 40 cm Dicke mit einem Rohr mit 20 Durchtrittsöffnungen, wobei die Behandlungszeit in beiden Fällen gleich lang ist.
  • - Sobald man alle Rohre angebracht hat und den Kompressor in Betrieb genommen hat, muss bis zum Ende der Behandlung keine Kontrolle erfolgen.
  • - Die Reinigung des ganzen Röhrensystems ist höchsteinfach, da man nurdiewasserabstossende Flüssigkeit durch Wasser ersetzen muss und man sich demgemäss die kostspielige Reinigung der Leitungen, Behälter und Schwämme durch geschultes Personal unter grossem Arbeitsaufwand erspart, die bisher erforderlich war.
  • - Da die Bohrungen, die in die Mauer eingebracht werden, einen kleinen Durchmesser aufweisen, ist keine Verminderung der Mauerfestigkeit zu befürchten.
With the method according to the invention and the device for carrying out the method according to the invention, all disadvantages of the prior art are overcome and the following advantages are achieved:
  • - Since the liquid is dispensed under pressure via a compressor, the passage openings of the perforated pipes sunk into the wall are prevented, however small these passage openings may be.
  • - The amount of water-repellent liquid that is introduced into the wall with each pulse and the time intervals between the respective pulses can be precisely metered and adjusted according to the porosity of the wall to be treated.
  • - In the method according to the invention there is neither reading, monitoring nor filling of a variety of containers as required in the prior art methods.
  • - You can treat walls of different thicknesses without having to monitor the supply of the water-repellent liquid depending on the wall thickness, because the amount of liquid to be supplied depends only on the number of through openings of the perforated pipes sunk into the wall; For example, if you treat a wall 20 cm thick with a tube with 20 openings, you treat a wall 40 cm thick with a tube with 20 openings, the treatment time being the same in both cases.
  • - As soon as all the pipes have been attached and the compressor started up, there is no need to check until the end of the treatment.
  • - The cleaning of the entire tube system is extremely easy, since you only have to replace the water-repellent liquid with water and accordingly you save the costly cleaning of the pipes, containers and sponges by trained personnel with great effort, which was previously required.
  • - Since the holes drilled in the wall have a small diameter, there is no fear of a reduction in the strength of the wall.

Nachstehend wird die Erfindung durch eine Ausführungsform der erfindungsgemässen Vorrichtung zur Dosierung von wasserabstossenden oder hydrophoben Flüssigkeiten durch Impulse genauer erläutert (Fig. 1 ).The invention is explained in more detail below by means of an embodiment of the device according to the invention for metering water-repellent or hydrophobic liquids by means of pulses (FIG. 1).

Die Vorrichtung besteht aus einer Kompressorgruppe 1 mit einem Elektromotor 2 und einer Pumpe 3, die die wasserabweisende Flüssigkeit durch ein Rohr 4 von einem Zentralbehälter 7 herführt, wobei die Flüssigkeit bei gleichbleibendem Druck in das ganze Leitungssystem eingeführt wird, der mit einem Ventil 6 regelbar ist. Von diesem Kompressor wird die Flüssigkeit einer Dosierungseinrichtung 8 zugeleitet, die mit hydromagnetischen Ventilen 9 versehen ist, die sich regelmässig gemäss den elektrischen Impulsen öffnen und schliessen, die sie von einem elektronischen Schalter 10 erhalten. Dieser Schalter weist einen Regler 14 für die Impulsdauer und einen Regler 15 für die Impulsfrequenz, eine Kontrollampe 12 für einen Hauptschalter 11 und Schalter 13 für die hydromagnetischen Ventile 9 auf.The device consists of a compressor group 1 with an electric motor 2 and a pump 3, which feeds the water-repellent liquid through a pipe 4 from a central container 7, the liquid being introduced into the entire line system at constant pressure, which can be regulated by a valve 6 . From this compressor, the liquid is fed to a metering device 8 which is provided with hydromagnetic valves 9 which open and close regularly in accordance with the electrical impulses which they receive from an electronic switch 10. This switch has a controller 14 for the pulse duration and a controller 15 for the pulse frequency, a control lamp 12 for a main switch 11 and switch 13 for the hydromagnetic valves 9.

Wenn die Ventile 9 geschlossen sind, fliesst die unter Druck stehende Flüssigkeit über ein Rücklaufrohr 5 in den Zentralbehälter 7 zurück. Wenn die Ventile 9 offen sind, fliesst die Flüssigkeit durch die Rohre 16, verteilt sich in den Verteilern 17, wobei sie die einfachen Kugelventile 20 passiert, die den Rückfluss der Flüssigkeit verhindern, gelangt zu den perforierten Rohren 18, die sich in der Mauer 21 befinden, und verteilt sich gleichmässig in der ganzen Dicke der Mauer. Die perforierten Rohre werden durch Befestigungselemente 90 in den Mauerbohrungen festgehalten.When the valves 9 are closed, the pressurized liquid flows back into the central container 7 via a return pipe 5. When the valves 9 are open, the liquid flows through the pipes 16, is distributed in the distributors 17, passing through the simple ball valves 20, which prevent the liquid from flowing back, reaches the perforated pipes 18, which are located in the wall 21 and is evenly distributed across the entire thickness of the wall. The perforated tubes are held in the wall holes by fasteners 90.

Die Dosierungseinrichtung 8 kann durch eine elektronische, hydraulische oder pneumatische Regeleinrichtung oder manuell gesteuert werden und hat die Aufgabe, die wasserabstossende Flüssigkeit in die Mauer zu den Zeitintervallen und in der Stärke zu drücken, die ein Operateur programmiert hat.The metering device 8 can be controlled by an electronic, hydraulic or pneumatic control device or manually and has the task of pushing the water-repellent liquid into the wall at the time intervals and in the strength that an operator has programmed.

Im allgemeinen ist die Mauer zum Beginn der Behandlung aufnahmefähiger für die Flüssigkeit als später, und daher müssen die Impulse anfangs mit einer höheren Frequenz und gegen Ende in grösseren Zeitabständen programmiert werden. Das Verhältnis zwischen der Absorption der Mauer und der Menge der zugeführten Flüssigkeit ist in Fig. 4 und im nachtehenden Beispiel erläutert.In general, the wall is more receptive to the liquid at the start of treatment than later, and therefore the impulses must be programmed initially with a higher frequency and towards the end at longer intervals. The relationship between the absorption of the wall and the amount of liquid supplied is illustrated in Fig. 4 and in the example below.

Beispiel:

  • Untersuchung der Absorption von Mauern mittlerer Porisität, hergestellt aus Vollziegeln und Zementmörtel
    • L = Dicke der Mauer (in cm)
    • A = normale Absorption der Mauer (in I/h)
    • C = Menge der wasserabweisenden Flüssigkeit, die gemäss dem erfindungsgemässen Verfahren mittels regelmässiger Impulse zugeführt wird (in I/h)
    • H = Dauer der Behandlung (in h)
      Figure imgb0001
Example:
  • Investigation of the absorption of walls of medium porosity, made of solid bricks and cement mortar
    • L = wall thickness (in cm)
    • A = normal absorption of the wall (in I / h)
    • C = amount of water-repellent liquid which is supplied by means of regular impulses according to the method according to the invention (in l / h)
    • H = duration of treatment (in h)
      Figure imgb0001

Das Verhältnis zwischen L, A, C und H ist in Fig. 4 gezeigt.The relationship between L, A, C and H is shown in FIG. 4.

Die Verbindungsrohre und die perforierten Rohre werden vorzugsweise aus Kunststoff, Kautschuk oder Metall hergestellt.The connecting pipes and the perforated pipes are preferably made of plastic, rubber or metal.

Die Bohrungen in der Mauer werden zur grösseren Sicherheit und zur besseren Verteilung der Flüssigkeit in doppelter horizontaler Linie durchgeführt, wie in Fig. 2 gezeigt ist.The holes in the wall are made in a double horizontal line for greater safety and better distribution of the liquid, as shown in Fig. 2.

Wie in Fig. 3 gezeigt ist, sind die perforierten Rohre 23 vorzugsweise 5 cm weniger lang, als die Stärke der Mauer beträgt (L), und die Durchtrittsöffnungen sind in gleichen Abständen M angebracht. Die Grösse dieser Abstände M kann je nach Mauerart 10 bis 100 mm betragen.As shown in FIG. 3, the perforated tubes 23 are preferably 5 cm less than the thickness of the wall (L), and the through openings are made at equal intervals M. The size of these distances M can be 10 to 100 mm, depending on the type of wall.

Die Durchtrittsöffnungen befinden sich auf einer geraden Längslinie auf dem perforierten Rohr 23, und dieses wird in der Bohrung der Mauer 22 mittels einer Kelle Gips 28 oder mittels einer Art Stopfen 29 aus elastischem Material befestigt, wobei die Linie der Durchtrittsöffnungen im perforierten Rohr 23 nach oben gerichtet sein soll. So bleiben die perforierten Rohre immer voll Flüssigkeit, sobald die Luft ausgestossen ist.The passage openings are located on a straight longitudinal line on the perforated tube 23, and this is fastened in the bore of the wall 22 by means of a trowel 28 plaster 28 or by means of a kind of stopper 29 made of elastic material, the line of the passage openings in the perforated tube 23 upwards should be directed. So the perforated tubes always remain full of liquid as soon as the air is expelled.

Die vom Kompressor und von der Dosierungseinrichtung kommende Flüssigkeit kann durch die Durchtrittsöffnungen in den in der Mauer angebrachten perforierten Rohren 23 tropfenförmig, strahlförmig oder zerstäubt abgegeben werden.The liquid coming from the compressor and from the metering device can be dispensed through the openings in the perforated tubes 23 provided in the wall in a drop-shaped, jet-shaped or atomized manner.

Das perforierte Rohr 23 ist zur Befestigung mit einem Metallring 27 versehen und ist mit dem Leitungsrohr 26 mit einer Muffe 25 verbunden. Das andere Ende des perforierten Rohres 23 ist mit einem Stopfen 24 verschlossen.The perforated tube 23 is provided with a metal ring 27 for attachment and is connected to the conduit 26 with a sleeve 25. The other end of the perforated tube 23 is closed with a stopper 24.
