Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • a section of a plate 1 made of concrete is shown, which for example forms the bottom of a collecting trough, not shown.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
