Definitions

  • the invention relates to a flat-bottom tank with a leak protection lining for storage of 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, especially in the area of the tank bottom. To make this possible, single-walled storage tanks must be retrofitted with an additional leak protection lining. It is also known, for example, to weld in an additional intermediate floor made of metal and to evacuate the resulting chamber or to keep it at a pressure which is below atmospheric pressure, in order to detect leaks early on by monitoring the pressure difference.
  • EP 0 705 771 A1 describes a method for producing a double-walled tank from a single-walled tank. Flat profiles are welded onto the inner tank wall and sheets are welded onto the flat profiles. From EP 0 069 303 B1 it is known to insert a knobbed film and an inner plastic cover in existing single-walled underground tanks for leak control in order to form a monitorable space between the tank wall and the stored goods. Since a plastic film is not electrically conductive, it is also proposed to arrange a metal film as a spacer onto which an electrically conductive fiber-reinforced epoxy layer is sprayed. The use of an electrically conductive polyurethane film for producing flexible inserts for containers is described in EP 0 571 868 A1.
  • the two layers also extend a little further up the side wall of the tank, the attachment of the knobbed film to the tank wall being effected by the applied epoxy resin layer.
  • an inner lining consisting of a double-sided film is known for a petrol tank. The film is held in the dome of the tank using a tension ring. Lining the entire interior of a tank to form a double wall is, however, very costly. From practice it is known that the connection of the film to the tank wall is difficult since the connection points have to be media and vacuum tight. In particular with steel storage tanks, it must also be taken into account that they are outdoors and are exposed to considerable temperature fluctuations. Additionally changing liquid levels in the containers also affect the expansion behavior of the container material.
  • DE-GM 67 51 479 discloses a storage container for liquids, in particular for heating oil. In the corner areas, this has connecting channels separated by baffles for vacuum generation and checking.
  • a plastic trough is used, which rests on sheets that serve as spacers. The edge zones of the plastic trough are glued or welded to the side walls of the container and, if necessary, still secured by pressure strips, not shown. The height of the plastic tub is such that the sludge deposit zone is covered.
  • the container is made of metal due to the required weldability of trapezoidal sheets. It should also be mentioned that the pressure strips can be pressed onto the gluing and welding points by screws with the interposition of elastic supports.
  • the storage container is cuboid and has a flat bottom and top plate. Such a container is not actually a flat-bottom tank. Since the leak protection lining consists of a rigid, stable, prefabricated plastic tub, the container ceiling must be removable in order to insert the plastic tub. The production of a separate plastic tub is associated with high costs. Precisely fitting plastic trays must be manufactured for different storage container dimensions. This solution is completely unsuitable for flat-bottom tanks, especially their retrofitting.
  • a flat-bottom tank with a leak protection lining which consists of at least one pressure-stable, cavity-forming insert and a media-resistant plastic film lying on this insert, the film extending into the lower area of the inside of the tank wall and into a distance from the tank bottom is circumferentially fastened on the inside by means of a clamping device, and the insert extends up to the clamping device.
  • the clamping device is usually above the maximum liquid level and consists of a circumferential tube which is pressed by means of clips against a base attached to the inner wall.
  • the invention had for its object to provide a flat-bottom tank with leak protection lining that is easy to manufacture and assemble, can be permanently attached to the tank wall in a media-tight and vacuum-tight manner, and meets the requirements for a leakage check.
  • the object is achieved by the features specified in claim 1. Suitable design variants are given in claims 2 to 14.
  • the leak protection lining for flat-bottom tanks consists of at least one pressure-stable, cavity-forming insert and a media-resistant plastic film lying on this insert. Before installing the leak protection lining as a retrofit, check whether the tank bottom meets the tightness requirements. If necessary, a corrosion-inhibiting dye paint is applied to the tank bottom or the tank bottom is coated with a liquid plastic.
  • the insert is placed thereon, which in a manner known per se consists, for example, of a plastic grid or a knobbed film.
  • the media-resistant film can also be provided on its underside with corresponding cavity-forming elements, such as knobs or the like. In certain applications it can also be useful to arrange a further film between the tank bottom and the insert. It is important that a suitable space for leakage monitoring is formed between the two foils or the foil lying on the insert and the tank bottom.
  • the flat-bottomed tank made of steel shown in FIG. 1 is single-walled and consists of the tank bottom 1 and the tank wall 2. Such a closed tank is intended, for example, for the storage of heating oil and has a diameter of 18 m and a height of 11 m.
  • the tank also has a closable opening designed as a manhole.
  • a plastic grid 3 consisting of PE-HD, is placed on the tank bottom 1 and has a height of 5 mm.
  • the plastic grid 3 serving as a cavity-forming insert covers the entire surface of the tank bottom 1 and in the area of the tank wall 2, starting from the tank bottom 1, is guided upward by about 100 mm.
  • the circumferential upper angled section 3 'of the plastic grille 3 lies circumferentially on the inside 2' of the tank wall 2.
  • a plastic film 4, consisting of PVC with a thickness of 1.5 mm, is placed on the insert 3 and pulled upwards in the area of the inner side 2 ′ over the section 3 ′ of the plastic grid 3.
  • the outer dimensions of the plastic film 4 are approximately 250 mm larger than the area of the tank bottom 1.
  • the film 4 is fastened to the inside 2 'of the tank wall 2 by means of a clamping device 5 (FIG. 2).
  • steel threaded bolts 6 are welded to the inside 2 'of tank wall 2 at a height of approximately 200 mm above tank bottom 1 distributed over the circumference.
  • the steel bolts 6 have a diameter of 10 mm and a length of 60 mm. They are spaced 150 mm apart and protrude into the tank interior.
  • holes are made at a distance from the bolts so that the fastening region 4' of the plastic film 4 can be pushed onto the bolts 6 without creases.
  • the elastic sealing tape can consist, for example, of polyurethane and has a thickness of 5 mm and a width of approx. 80 mm.
  • clamping rails 9 are plugged onto the bolts, the length of the clamping rails 9 being dimensioned such that they extend over a plurality of bolts 6.
  • the adjacent clamping rails 9 should rest against one another with their narrow end faces.
  • the clamping rails 9 are made of steel and have a width of 80 mm and a thickness of 8 mm, as well as correspondingly spaced holes for plugging onto the bolts 6.
  • 6 nuts 12 are screwed onto the threaded bolts and tightened using a torque wrench, a constant clamping voltage being set for all screw connections.
  • the foil located between the two sealing tapes 7 and 8 and the sealing tapes 7 and 8 are pressed firmly against the inside 2 'of the tank wall 2 by the clamping rails 9 and the clamping tension acting on them.
  • a media-tight and vacuum-tight connection is thus established between the inner wall 2 ', the sealing tapes 7 and 8 and the film arranged between the sealing tapes 7 and 8 and the clamping rails 9.
  • Below the clamping device 5 the bores required for arranging the vacuum measuring line 13 and the vacuum test line 14 are provided in the tank wall 2.
  • the wall thickness of the clamping rails 9 is dimensioned such that it is equal to or greater than the thickness of the tank wall 2.
  • FIG. 4 shows a section of a flat-bottom tank made of reinforced concrete. Such a tank is, for example, 8 m high and covered by means of a tank ceiling 16 resting on the side walls 2.
  • a plastic grid 3 with a height of 5 mm is laid on it, which covers the entire tank base 1 over the entire area.
  • a media-resistant plastic film 4 is placed on the plastic grid 3 and is pulled upwards on the inner sides 2 'of the tank wall 2 at a distance of approximately 400 mm from the tank bottom 1.
  • the clamping device 5 for fastening the plastic film 4 to the inside 2 'of the tank wall 2 is designed essentially analogously to the clamping device already described. In the corner areas, the clamping rails are designed as angle rails. Since the tank wall 2 consists of reinforced concrete, the fastening bolts 6 'are glued into corresponding bores in the tank wall 2 (FIG. 5).
  • the threaded bolts 6 'made of steel have a length of 100 mm and a diameter of 8 mm. After the threaded bolts 6 'have been glued into the tank wall 2, they protrude approximately 50 mm into the tank interior.
  • a sealing compound 17 is also applied directly on the upper edge of the clamping device 5, which is formed by the clamping rails 9, the sealing tapes 7 and 8 and the film 4 located between the sealing tapes 7 and 8.
  • a standpipe 18 made of plastic is welded into the plastic film 4 and is led upwards through the tank cover 16. In this standpipe 18 a sensor known per se is installed, which detects any leaks due to leaks in the film 4, which are displayed on a measuring device arranged outside the tank.
  • FIG. 9 A further configuration and arrangement of the clamping rails is shown in FIG.
  • the clamping rails 9 extend over a plurality of bolts 6 'and are attached to them. There is a defined distance in the circumferential direction between two adjacent clamping rails 9.
  • a compensating rail 9 'with two shoulders is inserted into this free space with a precise fit, the ends of the compensating rails 9' overlapping the adjacent clamping rails 9.
  • the length of the compensating rails 9 ' is greater than the distance between two bolts 6' and the fastening holes of the clamping rails 9 and the compensating rails 9 'are congruent.
  • 9 shows the embodiment variant according to the invention. In contrast to the previous FIGS. 1 to 7, FIGS.
  • FIG. 8 and 9 show embodiment variants in which the holder for the leak protection lining is not formed by bolts, but by a circumferential flange 19.
  • the circumferential flange 19 consists of several identical sections which are butt welded to the inside 2 'of the tank wall 2, each so that the flange 19 is fastened in a media-tight manner. Positions 20, 21 identify the two weld seams.
  • the welded flange 19 has a wall thickness of approximately 30 mm and a width of 80 mm.
  • Threaded bores 22 In the middle of the flange 19 there are threaded bores 22 at a distance of 150 mm each for receiving the threaded screws 23 with spring washers 24 for correspondingly fastening the film 4 by means of the clamping rails 9.
  • FIG. 9 shows a variant in which the leak protection lining only covers the tank bottom 1.
  • a circumferential flange 19 consisting of several identical parts is welded to the bottom and to the tank wall 2.
