Definitions

  • Connection system for fastening a flexible plastic film for leak protection lining on the inside of the tank wall of a storage tank
  • the invention relates to a connection system for fastening a flexible plastic film for leak protection lining on the inside of the tank wall of a tank for storing water-polluting media.
  • Flat-bottom tanks are made of steel or reinforced concrete and are mainly used to store fuels, mineral oils, acids, alkalis, solvents or the like. In practice, both single-walled and double-walled flat-bottom tanks are used. For environmental reasons, there is a need to monitor the flat-bottom tanks for leaks. To make this possible, single-walled storage tanks must be retrofitted with an additional leak protection lining. A so-called second wall or inner wall is formed by a leak protection lining and the single-walled storage tank is thereby converted into a double-walled storage tank.
  • the leak protection lining covers at least the tank bottom and can extend to the tank fill opening according to the given requirements or can be attached to the inside of the outer wall of the tank at a certain height.
  • Two different systems are known as leak protection linings based on plastics.
  • One relates to a lining with a fixed inner wall and the other to a lining with a flexible film.
  • the other system consists of a pressure-stable cavity-forming insert and at least one media-resistant flexible plastic film resting on this insert, e.g. B. made of PVC, which lies loosely on the tank wall or the cavity-forming insert and is attached to the tank wall.
  • this insert e.g. B. made of PVC
  • This solution does not guarantee a permanent media and vacuum tight connection between the lining foil and the tank wall.
  • the clamping device consists of bolts arranged at the same height, fixed in or on the tank wall at defined intervals and projecting inwards, onto which the clamping rails can be attached. Between the clamping rails and the film as well as the film and the inside of the tank wall, elastic sealing tapes are arranged all around. The clamping rails are locked under pressure on the bolts.
  • a leak protection lining (DE 299 18 485 U1), in which a fastening bracket is arranged in the corner area between the tank wall and the tank bottom, the leg of which runs parallel to the tank wall and is connected to the tank wall in a media-tight manner.
  • the film lying on the cavity-forming insert is attached in a media-tight manner to the leg of the fastening bracket which runs parallel to the floor.
  • the invention has for its object to provide a connection system for attaching a flexible plastic film for leak protection lining on the inside of the outer wall of a storage tank, which requires little installation effort and ensures permanent and reliable tightness. According to the invention the object is achieved by the features specified in claim 1. Suitable design variants are the subject of claims 2 to 14.
  • the proposed connection system consists at least of a strip-shaped sealing membrane and an adapter film.
  • the sealing membrane represents the actual carrier material and has an upper fastening section, which is attached to the inside of the tank wall by means of an adhesive based on plastic, and a lower fastening section, which overlaps the adapter film and is connected to it by gluing or welding.

  • the dimensions of the lining film and the adapter film are matched to one another in such a way that the weld seam is located in the area of the floor.
  • the height of the attachment points on the tank wall, their Distance from the tank bottom depends on the specified lining conditions.
  • the adapter film can be connected to the lower section of the sealing membrane either by welding or gluing. However, a welded connection is only possible if this section consists of a weldable plastic. If the connection between the adapter film and the sealing membrane is made by gluing, the adapter film can also be glued to the tank wall in the area of its upper edge. This variant is used when there are particularly high demands on the tightness of the connection point.

  • a reaction resin based on epoxy or polyester resin is used as the adhesive, which is then finally applied to the top of the fabric or mat in order to achieve a high level of tightness at the connection points.
  • the adapter film should be perforated in the area of the joint so that the resin can penetrate the adapter film and an improved adhesion of the film is achieved. After the resin has hardened, a stable strip-shaped sealing membrane is created, which is permanently and firmly connected to the tank wall and the adapter film.

It is also possible to manufacture the actual lining film, the adapter film and the sealing membrane from the same material. However, the waterproofing membrane should be at least twice as thick as the lining film. It can also consist of a prefabricated composite material, e.g. a glass fiber reinforced film. The adapter film can also be reinforced, at least in the fastening area. e.g. by another laminated film strip or a reinforcement insert.

  • Two-component adhesives based on epoxy resin can be specifically adjusted in terms of their properties and also enable curing at room temperature.

  • elastic expansion means are arranged circumferentially or in sections between the adapter film and the inside of the tank wall, which are compressed into a flat state during the filling of the tank. The expansion means prevent the lining film and the adapter film from wrinkling in the lower region.
