Definitions

  • the invention relates to a device for collecting leakage liquids in the region of a filling pipe arranged in a dome shaft, which opens through a dome cover into an underground storage container for fuels, heating oil or the like , flexible, leakage-resistant grass catcher is interchangeably arranged without interlocking with respect to the manhole with manhole cover.
  • the collection bag is not emptied in time, which is to be done by removing the entire collection bag or by suctioning off the liquid collected in the collection bag, the liquid collected in the collection bag can reach the dome shaft via the upper edge of the collection bag because a complete seal between the Dome shaft side walls and the upper edge of the collecting container is not guaranteed, mixes there with the water usually located in the dome shaft and from there more or less quickly diffuses into the groundwater.
  • groundwater pollution By this seeping into the ground or groundwater, environmental damage, namely groundwater pollution, is caused in many cases, the elimination of which causes extremely high costs, the groundwater pollution can be increased by the fact that the oils or fuels bypass the outer insulation of the containers and in addition to damage to the insulation and thus the risk of rusting through the outer wall of the container also trigger other pollutants from the insulation and wash them into the groundwater.
  • a device in which at the lower end of the collecting container the so-called sludge quantities can be fed directly to the storage container, but which is otherwise not of the generic type because this is a device a dome shaft with manhole cover formed from concrete with formwork and an upper end ring and the actual collecting container are positively connected to one another in such a way that all vertical forces which are exerted on the dome shaft with a manhole cover, in particular by heavy tank vehicles, are also transmitted directly to the collecting container .
  • a clean separation of filling liquid and dirty water or the like is not guaranteed in this known device, because when the manhole cover is opened, for example during a filling process taking place in the rain, dirty water can immediately get into the collecting container, which in turn leads to the return of the leakage liquid to the storage container excludes.
  • the object of the invention is to provide a solution which, while maintaining the advantages of a device positively locking assignment of the collecting container to the dome shaft with manhole cover (according to US-A-4 579 155) avoids the disadvantages which still exist and are described above.
  • this is achieved according to the invention in that the upper edge of the collecting bag is arranged all around at a distance from the dome shaft side walls in such a way that dirty water or the like pass between the dome shaft side walls and the upper edge of the collecting bag and deforming forces cannot be transferred from the dome shaft with the manhole cover to the collecting sack, furthermore a leakage-liquid-resistant cover is assigned to the collecting sack in addition to the manhole cover and finally an outlet is arranged in the lowest area of the collecting sack, which opens into the filling tube above the manhole cover.
  • This design ensures that the amount of slobber that inevitably occurs when filling the storage container in question is automatically discharged into the container immediately, so that on the one hand this slobber amount is not lost and on the other hand can no longer cause environmental damage.
  • dirty or rainwater or other contaminants unavoidable in the petrol station area are unhindered and can be discharged harmless to the contents of the container, namely can get into the ground through the space between the side walls of the cathedral shaft and the liquid-tight collecting container without causing significant environmental damage there.
  • the solution according to the invention makes it possible to leave the lower end of the cathedral shaft open and to enter detoxifying agents such as bacterial cultures or the like from time to time. so that even heavily contaminated surrounding areas can be increasingly disposed of in containers that have been in operation for a long time without the protective device according to the invention after installation of the device according to the invention.
  • the distance between the dome shaft side walls and the upper edge of the collecting container at the same time prevents the transmission of any constraining forces from the dome shaft with the manhole cover to the collecting container.
  • the lid directly assigned to the collecting container in addition to the manhole cover ensures that condensation water, rust particles or the like cannot fall from the underside of the manhole cover into the collecting container, which would otherwise preclude the discharge of the amounts of sludge into the actual liquid container.
  • the device according to the invention has the fundamental advantage that by separating the actual dome shaft with an upper end cover for receiving vertical Loads and the actual fall arrester no vertical loads can be transferred to the filling pipe or the tank, which means that there is a risk of deformation or breakage and thus environmental pollution at the resulting break points.
  • the upper edge of the collecting bag is arranged on telescopic vertical rods which can be fastened to the dome cover, because this makes it particularly easy to retrofit storage containers already in operation with the subject matter of the invention.
  • a complete separation of the actual collecting container with this associated parts from the dome shaft with manhole cover is achieved, so that the possible impairment of form-fitting-free bearings for the upper edge of the collecting bag on the dome shaft side walls is also eliminated by the large vertical loads exerted on them.
  • the drain at the lower end of the collecting bag can - as known from US-A-4 659 251 - in the form of a bypass with a check valve train such that gas tightness of the reservoir is ensured by the check valve.
  • a limit indicator is arranged in the collecting bag in such a way that the liquid supply via a filling hose connected to the filling tube is interrupted when a predetermined filling level in the collecting bag is reached. This ensures in any case that a larger liquid supply, i.e. one which exceeds the capacity of the collecting container cannot occur even if e.g. the automatic process should not take place, for example, due to a blockage of the process or a malfunction of the valve provided in it, or if the operator should not interrupt the fluid supply through the filling hose in good time.
  • the limit transmitter arranged in the collecting bag can also be connected in parallel to a limit transmitter which prevents the supply of the filling liquid when a predetermined fill level is reached in the storage container.
  • the upper edge of the collecting bag can rest in hook-shaped, adjustable bearings in such a way that the collecting bag can be lifted upwards in order to be able to release the space above the dome cover for inspection and maintenance purposes.
  • a double-walled fuel earth container 1 is provided with a filling dome 2, which is closed by a dome cover 3.
  • a fill tube 4 and a dip tube 5 provided with a mechanical dipstick and a limit indicator 6 extend through the dome cover.
  • a fuel line 7 leading to petrol pumps, a vent 8 and a so-called gas pendulum 9 are also connected to the dome cover.
  • a dome shaft 10 is bricked or concreted with a shaft frame 11 and a shaft cover 2 mounted in it and aligned with the top edge of the terrain.
  • a flexible and leakage-resistant collecting bag 13 is arranged, which is formed with sleeves 14 and 15 that are rolled up like a bellows, each of which is fixed with a reinforced opening edge with a fastening clip 16 or the like in a sealing manner on the filler pipe 4 or dipstick 5, as shown in particular in FIG 1 can be seen.
  • the open-top collecting bag 13 is provided with a fastening edge 17, preferably a metal ring embedded in the material of the collecting bag or fastened in loops of the same and belt-like and can be hung with this in upwardly open, hook-like and adjustable bearings 18, which in turn are fastened to the shaft walls.
  • the dome shaft 10 with the shaft frame 11 has a square floor plan, while the grass bag 13 is circular in plan, the arrangement being such that there is a sufficient distance between the shaft frame 11 and the upper fastening edge 17 of the grass bag 13 is present, so that on the edge of the shaft frame 11 seeping rain or melt water does not get into the grass-catcher, but through the gap can seep into the ground between this and the shaft walls. From Fig. 1 it can also be seen that the upper ends of the filling tube 4 and the leveling tube 5 end a little below the upper edge 17 of the collecting bag 13.
  • the collecting bag 13 there is also a further limit indicator 27, which is connected in parallel with the first limit indicator 6, in such a way that overfilling of the collecting bag 13 is prevented when a predetermined fill level is reached, in particular if overfilling due to a leak in the connection between the filling tube 4 and threatens with this connected filling hose.
  • the collecting bag 13 is also protected with a cover 26 against contamination or against the ingress of rainwater, which could get into the collecting bag through openings in the manhole cover 12 without the cover 26. This also applies to condensation water and / or rust particles on the underside of the manhole cover 12.
  • An outlet is formed at the deepest point of the collecting bag 13 in the form of a bypass 20 with a check valve 21, in such a way that leakage liquid is continuously fed directly from the collecting bag 13 to the main liquid in the storage container 1.
  • the bearings 18 are arranged at the upper ends of telescopic vertical rods 29 so that they can be adjusted in height and side, the angled lower ends of which are fastened to the dome cover 3 by means of fastening screws 30. This eliminates the need for fastening to the side walls of the shaft or retrofits the object of the invention to storage containers that are already in operation.
  • a filling hose located on a transport vehicle is connected to the filling pipe 4 provided with a corresponding coupling half and the fuel is poured into the tank 1 until the limit indicator 6 interrupts the fuel supply. Then the coupling between the filling hose and the filling pipe is released and the so-called amount of sludge which inevitably escapes is collected in the collecting bag 13 in such a way that practically no filling liquid can get into the dome shaft 10 and the soil beneath it via the upper edge 17 of the collecting bag 13.
  • the effect of the collecting bag 13 when pulling up or reinserting a mechanical dipstick located in the dipstick 5 is very similar, in which it depends on each level can often occur that liquid "slurps" over the upper end of the dip tube.
  • the so-called slobber liquid collects in the lower region of the collecting bag 13 and flows continuously from it via the bypass outlet 20 directly into the container 1.
  • the tubes for limit switches 6 and gas pendulums 9 can be shaped in such a way that the relevant devices in the corners of the manhole frame are easily accessible after removing the manhole cover 12.
  • the illustrated and described design of the collecting bag 13 makes it possible to lift the collecting bag a little and then put it to the side without loosening the sealing sleeve 16 from the filling pipe and the sighting pipe, so that the dome shaft 10 is then easily accessible for inspection and / or repair purposes.
  • the production of the collecting bag 13 from materials which are resistant to the filling liquids is easily possible in one piece with the cuffs which are turned out from the bottom by means of conventional techniques, as has been the case for a long time for the liquid-tight confluence of several Cable in cable sleeves, for example according to DE-B-26 55 548 is known.
  • the grass-catcher bag can be designed differently than circular, for example in adaptation to appropriately rectangular domed shafts oval or the like.
  • the grass-catcher bag according to the invention is suitable not only for earth containers for fuels and heating oils but also for all other liquids that prevent their soaking into the ground should be and so on.
