Definitions

• a method and construction element for establishing systems for provisional storage of potentially leaking containers with dangerous liquid is provided.
• the present invention relates to the use of refuse containers and more explicit to ah installation for temporary storage of such containers.
• the invention aims at the type of containers that has approximately the same extension as a usual platform body on a truck, with side walls rising to bigger or smaller height, and accommodated to be delivered and picked up by means of special container trucks provided with a hauling winch, which by the use of pulling wires, can haul up a container to be carried on a special support.
• the single flat tanks can easily be provided with a relatively weak roof construction, to drain the rain without having the character of a fixed roof construction.
• movable roof units on suitable stay rods can be used, only to be lashed to stabilise the units against wind.
• the flat tanks must be made in a heavy construction in a corrostable way, but in this case it is an advantage that they are just reckoned to receive standardized units, in such a way that on the inside they can have infilling profiles stretching along just the stretches where the refuse containers themselves have ground supporting profiles; thereby the load is transmitted to the ground directly by the infilling profiles, to enable the flat tanks to carry very great loads without the tanks otherwise or as a whole having to be extremely heavy.
• the refuse containers are usually made with an outer width corresponding the permissible maximum for transportation on roads, and for the same reason the flat tanks cannot be made with a still greater width. It is very important that they can collect the leaking liquid from the side edge area of the containers, because these areas are particularly liable to be leaky, and on this background, it is a special feature of the invention that the flat tanks can be constructed with the concerned maximum width or even slightly narrower than this and, in addition, be provided with attachable or pivotable sidewalls which, in the parking position, can be placed as outwardly and inwardly projecting hopper walls along the upper lateral edges and, if required, also along the end edges.
• the flat tanks should be mounted or supported in such a way that their top sides are slightly sloping against one end, at which one or more simple inlet holes can be provided, through which even an emptylng with a sludge exhauster hose can be effected.
• the tanks are made with a rigid underframe, mounted sloping thereon, such that the tank inclination, which is also of significance for an effective emptylng, is suitable when the tank is placed on an approximately horizontal base.
• the supporting area for the containers is at a certain small height over the base level, for example 50 cm. It is important, however, that the tanks are correspondingly raised slightly above the base, because they can then be visually inspected for tightness.
• Fig. 1 is a partly sectional perspective front view of an embodiment of a tank according to the invention, seen from above,
• Fig. 2 is a perspective view of the rear part of the tank.
• Fig. 3 is a perspective view of the tank and a scrap container placed upon it.
• the flat tank shown i Fig. 2 is made as a flat box construction, for example by steelplates with a thickness of 4 am.
• the tank is built on a supporting frame fully corresponding to the carrying frame of standard refuse containers, of the container at the top of Fig, 3, viz. a pair of lengthwise supporting bars 4 below, to which there is fixed a number of overlapping transverse bars 6 supporting the bottom plate of the overlying container structure.
• the bars 4 as usually, continue in upright front supporting parts 8, which can make a stop against the fixed parts of a container truck by hauling up the unit on such a truck.
• the transverse bars 6 have a rearwardly decreasing height dimension, such that the flat tank will be slightly sloping downward and rearwardly, when it is placed with its bars 4 on a substantially horizontal base.
• the inner profile irons 10 are at their rear ends provided with lower throughpassages 12, such that liquid can be distributed throughout the tank.
• the upper surface on the tank is provided with low upright edge sheet parts 14, by which the surface of the tank forms a tray for liquid leaking from a refuse container placed upon the flat tank.
• a pair of holes 16 is provided in top plate of the tank, through which such collected liquid can be lead down to the inside of the tank 2.
• these holes there may be retractable grids 18, see Fig. 2, such that only small impurities can soak into the tank.
• the grids 18 can be picked up when the tank is due to be emptied, by guiding a sludge exhauster hose through one or both of the holes.
• roller 22 At the bottom in the rear end, by which it is possible to roll this end of the container on the base when the front end is lowered along the loading ramp of the container truck by unloading of the container or, respectively, when the container is hauled onto the ramp by loading.
• the flat tank should be provided with a similar roller 24, Fig. 2, but because the roller projects a little below the bottom plane of the longitudinal bars 4 it is preferred that this roller is fitted up in a detachable way, as shown in Fig. 3, where it is removed after unloading the tank. It can be remounted (not shown) when the tank has to be moved.
• the upper side of the flat tank is designed with a view to receiving and delivering of containers having such rollers 22.
• a reinforced rolling path is provided in the shape of a sheet strip 26, for example a 5 mm steel sheet, which at the rear end continues in a countersinking 28, in which the container roller fits in such a way that the longitudinal bars 4 at the bottom of the refuse container may be in contact with the upper side of the flat tank over their entire length, for an even distribution of the pressure.
• a drainhole to the inside of the tank.
• a level indicator 34 in the rear the tank is provided with a level indicator 34, Fig. 2, which may be of any suitable type.
• edge sheets 36 which will safely catch leaking liquid from the side areas of the received refuse container.
• edge ⁇ heets are not rigidly mounted from the beginning, because they have to be dismounted or swung inwardly when the tank is transported on a road by a container truck.
• they are made of a strong rubber, but it is not significant for the invention, how they are made or fixed.
• the tank is provided with bollards 38, in quite the same way as refuse containers, as guidance for relevant pulling wires, for which fixing eyes are provided on the side of the bars under the bottom of the container.
• the flat tanks according to the invention will, besides, be usefull for temporary storage of other types of containers, for example barrels in connection with clean out works, as one or more flat tanks can easily be moved to a convenient location in the working area.
• flat tanks can be used more or less stationary at places, for example in industrial plants, where it is relevant to have temporary storage of potentially leaking containers with more or less dangerous contents.
• the tanks are most easily emptied by the use of a sludge exhauster, but if the holes 16 can be shut tightly, another option will be to move a more or less full flat tank, driven directly on a container truck, to be emptied at an authorized location.
