Abstract

A liquid-tight lining which is resistant to chemical attack for catch reservoirs, containers or the like of concrete. The lining includes a continuous liquid-tight impervious layer provided above the surface of the concrete. To make possible a simple and safe and repeatable testing of the tightness of the lining, a porous intermediate layer is provided between the concrete and the impervious layer. At least one sensor cable having at least two conductors is placed in the intermediate layer in such a pattern that any location of the intermediate layer is not more than a certain maximum distance away from the cable. The sensor cable is connectible to an electrical monitoring unit.

Description

Die Erfindung bezieht sich auf einen chemisch beständigen, flüssigkeitsdichten Belag für Auffangräume, Behälter oder dgl. aus Beton, bestehend aus einer vollflächigen, ober­halb der Betonoberfläche befindlichen, flüssigkeitsdichten Isolierschicht.The invention relates to a chemically resistant, liquid-tight covering for collecting rooms, containers or the like made of concrete, consisting of a full-surface, liquid-tight insulating layer located above the concrete surface.

Aufgrund gesetzlicher Bestimmungen sind die Wasserbehörden gehalten, für Anlagen zum Lagern, Abfüllen und Umschlagen wassergefährdender Stoffe einen Eignungsnachweis zu führen. Sofern Abdichtungsmittel aus Kunststoff oder Gummi verwen­det werden, müssen diese ein Prüfzeichen des Instituts für Bautechnik besitzen. Diese Bestimmungen haben in der Praxis dazu geführt, daß für Auffangwannen, Auffangräume und Behäl­ter aus Beton entweder Kunstharzbeschichtungen oder Gummi- oder Thermoplastbahnen verwendet werden. Zu den Anforderun­gen, die an diese Matrialien gestellt werden, gehören chemische Beständigkeit, Witterungsbeständigkeit, Bestän­digkeit gegen Bakterien und Nagetierverbiß, Rißüberbrückung und dgl. Neben einer Dichtigkeitsprüfung bei der Erstellung der Auffangwannen, Auffangräume und Behälter besteht auch die Forderung, die Dichtigkeitsprüfungen ohne Schwierigkei­ten in regelmäßigen oder unregelmäßigen Abständen wiederho­len zu können. Aus dem Bereich des Säureschutzbaues ist es bekannt, daß Beschichtungen aus Kunstharz und Auskleidungen aus Gummi- oder Thermoplastbahnen nicht ausreichend gegen mechanische Beanspruchungen, wie sie zum Beispiel durch das Befahren mit Lastkraftwagen und Staplern auftreten, stabil sind. Aus diesem Grunde werden im Säureschutzbau die Abdich­tungen aus Kunstharzbeschichtungen und Gummi- oder Thermo­plastbahnen zusätzlich mit keramischen Platten belegt. In vielen Fällen ist auch die chemische Beständigkeit der Ab­dichtungsmittel nur in Kombination mit einem Plattenbelag zu erzielen. Dabei verhindert die zusätzliche Plattenlage jedoch die Wiederholung der Dichtigkeitsprüfung im Bereich der Beschichtungen oder Auskleidungen. Dazu wäre es nämlich erforderlich, die Plattenlage zu entfernen, was mit einer Zerstörung der Beschichtung oder Auskleidung verbunden ist.Due to legal regulations, the water authorities are required to provide proof of suitability for systems for storing, filling and handling water-polluting substances. If plastic or rubber sealants are used, they must have a test mark from the Institute of Building Technology. In practice, these provisions have resulted in the use of either synthetic resin coatings or rubber or thermoplastic webs for collecting trays, collecting rooms and containers made of concrete. The requirements placed on these materials include chemical resistance, weather resistance, resistance to bacteria and rodent bite, crack bridging and the like.In addition to a leak test when creating the collecting trays, collecting rooms and containers, there is also the requirement that the leak tests be carried out regularly without difficulty or to be able to repeat irregular intervals. It is from the area of acid protection It is known that coatings made of synthetic resin and linings made of rubber or thermoplastic webs are not sufficiently stable against mechanical stresses such as occur, for example, when driving on trucks and forklifts. For this reason, the seals made of synthetic resin coatings and rubber or thermoplastic sheets are additionally covered with ceramic plates in acid protection construction. In many cases, the chemical resistance of the sealant can only be achieved in combination with a panel covering. However, the additional plate layer prevents the repetition of the leak test in the area of the coatings or linings. To do this, it would be necessary to remove the plate layer, which would result in the destruction of the coating or lining.

Der Erfindung liegt deshalb die Aufgabe zugrunde, einen chemisch beständigen, flüssigkeitsdichten Belag für Auffang­räume, Behälter oder dgl. aus Beton zu schaffen, der sich in einfacher und sicherer Weise auch wiederholt auf Dichtig­keit überprüfen läßt.The invention is therefore based on the object of providing a chemically resistant, liquid-tight covering for collecting rooms, containers or the like made of concrete which can also be checked repeatedly for tightness in a simple and safe manner.

Zur Lösung dieser Aufgabe wird gemäß der Erfindung vorgeschla­gen, daß zwischen der Betonschicht und der Isolierschicht eine poröse Zwischenschicht mit mindestens einem mit einem elektrischen Überwachungsgerät verbindbaren, zumindest zwei­adrigen und mit Abstand voneinander flächendeckend verlegten Sensorkabel angeordnet ist.To achieve this object, it is proposed according to the invention that between the concrete layer and the insulating layer a porous intermediate layer is arranged with at least one sensor cable that can be connected to an electrical monitoring device, is at least two-wire and is laid so as to be spaced apart from one another.

Das mit dem Sensorkabel verbindbare Überwachungsgerät über­wacht - je nach Art der zu überwachenden Flüssigkeiten - kontinuierlich den elektrischen Widerstand des Sensorkabels oder dessen Impedanz und gibt bei Einwirkung von durch die Isolierschicht hindurchtretende Flüssigkeiten ein Alarm­signal ab. Die poröse Zwischenschicht hat dabei die Aufgabe, die durch die Isolierschicht hindurchtretende Flüssigkeit zum nächstgelegenen Sensorkabel zu leiten. Die Zwischenschicht muß dabei eine für die zu erwartenden mechanischen Beanspru­chungen ausreichende Festigkeit besitzen.The monitoring device, which can be connected to the sensor cable, continuously monitors the electrical resistance of the sensor cable or its impedance, depending on the type of liquids to be monitored Liquids passing through an alarm signal. The porous intermediate layer has the task of guiding the liquid passing through the insulating layer to the closest sensor cable. The intermediate layer must have sufficient strength for the mechanical stresses to be expected.

Weitere Merkmale der Erfindung sind in den Ansprüchen 2 - 9 offenbart.Further features of the invention are disclosed in claims 2-9.

Die Erfindung wird nachfolgend anhand in einer Zeichnung dar­gestellter Ausführungsbeispiele näher erläutert. Dabei zeigen

  • Fig. 1 einen Schnitt durch einen Belag gemäß der Erfindung und
  • Fig. 2 eine weitere Ausbildung eines Belages.
The invention is explained in more detail below with reference to exemplary embodiments shown in a drawing. Show
  • Fig. 1 shows a section through a covering according to the invention and
  • Fig. 2 shows a further formation of a covering.

In der Fig. 1 der Zeichnung ist ausschnittsweise eine Platte 1 aus Beton gezeigt, die beispielsweise den Boden einer nicht näher dargestellten Auffangwanne bildet. Auf dieser Platte 1 ist eine poröse Zwischenschicht 2 aus Estrich aufgebracht, die ein begrenztes Aufnahmevermögen für Flüssigkeiten besitzt. In dieser Zwischenschicht sind Nuten 3 vorgesehen, die ent­weder direkt bei der Herstellung der Zwischenschicht 2 oder durch einen nachträglichen Arbeitsvorgang gefertigt werden. Die Nuten 3 können entweder meander- oder spiralförmig in der Zwischenschicht 2 angeordnet sein und weisen einen sol­chen Abstand voneinander auf, daß die gesamte Fläche der Platte 1 flächendeckend von einem in den Nuten 3 verlegten Sensor­kabel 4 erfaßt werden kann. Auf der Zwischenschicht 2 ist eine Isolierschicht 5, beispielsweise aus einer Gummibahn aufgebracht. Durch die poröse Zwischenschicht 2 wird die durch eine defekte Isolierschicht 5 hindurchtretende Flüssigkeit zum nächstgelegenen Sensorkabel 4 geleitet.In Fig. 1 of the drawing, a section of a plate 1 made of concrete is shown, which for example forms the bottom of a collecting trough, not shown. On this plate 1, a porous intermediate layer 2 made of screed is applied, which has a limited absorption capacity for liquids. Grooves 3 are provided in this intermediate layer, which are either produced directly during the production of the intermediate layer 2 or by a subsequent work process. The grooves 3 can be arranged either in a meandering or spiral shape in the intermediate layer 2 and are at such a distance from one another that the entire surface of the plate 1 can be covered area-wide by a sensor cable 4 laid in the grooves 3. An insulating layer 5, for example made of a rubber sheet, is applied to the intermediate layer 2. The liquid passing through a defective insulating layer 5 is passed through the porous intermediate layer 2 to the closest sensor cable 4.

Die Sensorkabel 4 können im einfachsten Fall zweiadrige Bänder sein, deren Widerstand sich bei der Einwirkung von Wasser oder anderen elektrisch leitenden Flüssigkeiten ändert. Bei einer mehradrigen Ausbildung der Sensorkabel 4 ergibt sich die Möglichkeit, eine Leckstelle durch entsprechende, zusätz­liche elektrische Schaltungen zu lokalisieren. Für nicht elektrisch leitende Flüssigkeiten werden Sensorkabel 4 ver­wendet, deren Impedanz sich durch die Einwirkung von organi­schen Stoffen, beispielsweise Lösemittlen, ändert. Der Abstand zwischen den Sensorkabeln 4 richtet sich im wesentlichen nach der Ausbreitungsgeschwindigkeit der Flüssigket in der porösen Zwischenschicht 2 und der gewünschten Ansprechzeit eines nicht dargestellten, elektrischen Überwachungsgerätes.In the simplest case, the sensor cables 4 can be two-wire tapes, the resistance of which changes when exposed to water or other electrically conductive liquids. With a multi-core design of the sensor cable 4, there is the possibility of locating a leak by means of corresponding, additional electrical circuits. Sensor cables 4 are used for non-electrically conductive liquids, the impedance of which changes as a result of the action of organic substances, for example solvents. The distance between the sensor cables 4 depends essentially on the speed of propagation of the liquid in the porous intermediate layer 2 and the desired response time of an electrical monitoring device, not shown.

Bei dem Ausführungsbeispiel der Fig. 2 ist unterhalb der porö­sen Zwischenschicht 2, also zwischen der Zwischenschicht 2 und der Betonplatte 1 bzw. Betonwand eine weitere Isolierschicht 6 vorgesehen, die aus einer Gummi- oder Thermoplastbahn be­stehen kann. Dabei sind die einzelnen Bahnen dichtend mitein­ander verbunden. Eine derartige Isolierschicht 6 wird dann vorgesehen, wenn aus dem Untergrund Feuchtigkeit zu erwarten ist. Diese Isolierschicht 6 verhindert, daß aufsteigende Flüs­sigkeiten, beispielsweise Grundwasser, falsche Alarmmeldungen im Überwachungsgerät hervorrufen. Außerden begrenzt diese Isolierschicht 6 den Schadensumfang für den Fall, daß durch die Isolierschicht 5 bereits eine größere Menge Flüssigkeit in die Zwischenschicht 2 eingedrungen ist. Durch das begrenz­te Volumen der Zwischenschicht 2 wird in Verbindung mit den beiden Isolierschichten 5,6 ein Doppelboden geschaffen, der einerseits aufgrund des begrenzten Volumens eine schnelle Anzeige gewährleistet und andererseits einen größeren zeit­lichen Spielraum für die Einleitung von Gegenmaßnahmen schafft. Bedarfsweise kann unter der Isolierschicht 6 noch eine elek­trisch leitende Kunstharzschicht 7, beispielsweise aus Epoxid­harz, angeordnet sein, die nach der Herstellung der Isolier­schicht 6 zur Porenprüfung derselben dient.In the embodiment of FIG. 2, a further insulating layer 6 is provided below the porous intermediate layer 2, that is between the intermediate layer 2 and the concrete slab 1 or concrete wall, which may consist of a rubber or thermoplastic sheet. The individual sheets are sealed together. Such an insulating layer 6 is provided when moisture is expected from the subsurface. This insulating layer 6 prevents rising liquids, for example groundwater, from causing false alarm messages in the monitoring device. In addition, this insulating layer 6 limits the extent of damage in the event that a larger amount of liquid has already penetrated into the intermediate layer 2 through the insulating layer 5. The limited volume of the intermediate layer 2, in conjunction with the two insulating layers 5, 6, creates a raised floor, which on the one hand ensures a quick display due to the limited volume and on the other hand creates greater time scope for initiating countermeasures. If necessary, an electrically conductive synthetic resin layer 7, for example made of epoxy resin, can also be arranged under the insulating layer 6, which serves to check the pores after the insulating layer 6 has been produced.

Im Ausführungsbeispiel der Fig. 2 ist oberhalb der Isolier­schicht 5 ein Belag aus keramischen Platten 8 vorgesehen, der in einer Schicht 9 aus Verlege- und Verfugekitt oder Zement­mörtel verlegt ist.In the exemplary embodiment in FIG. 2, a covering of ceramic plates 8 is provided above the insulating layer 5, which is laid in a layer 9 of laying and jointing cement or cement mortar.

Das Sensorkabel 4 kann in mehreren Meßschleifen verlegt werden, wobei besonders gefährdete Bereiche der Platte 1, beispielsweise Kanäle und Dehnungsfugen von einem gesonder­ten Sensorkabel 4 bzw. einer eigenen Meßschleife überwacht werden.The sensor cable 4 can be laid in several measuring loops, particularly vulnerable areas of the plate 1, for example channels and expansion joints, being monitored by a separate sensor cable 4 or its own measuring loop.
