Definitions

the present invention concerns a device for sealing pits, in particular a device which consists of a horizontal frame and cover means fitting in the frame, such as a lid.
odour seals usually consist of grooves in the form of ducts which are provided in the above-mentioned frames and ribs on the bottom side of the lids which extend into the above-mentioned ducts, one and other such that when the ducts are filled with water, a barrier is formed for the odour rising from the pit.
the pit lids can seal in a watertight manner. This is among other the case in control rooms which are situated above the lid of a tank, such as a fuel oil tank.
a tank such as a fuel oil tank.
various solutions have already been suggested, including the use of elastic sealing rings.
the known devices for sealing pits whereby an odour seal and/or a seal to prevent the penetration of liquid, such as rain water, is provided, are all disadvantageous in that they no longer meet the above-mentioned requirements after some time, especially when the pit lids used hereby are heavily loaded, for example by vehicles driving over them. Many of the usual defects hereby arise as the pit lids bend and the seatings, where the lids rest in the frames, are damaged. This phenomenon particularly occurs with synthetic lids.
Document GB 2 148 362 discloses a device for sealing pits, having a lid provided with two ribs on its bottom side fitting into concentric ducts of a supporting frame.
the construction known herefrom does not exclude the penetration of water.
the present invention aims a device for sealing pits which does not have the above-mentioned disadvantages, in other words whereby an optimum sealing is provided on the one hand, in order to prevent that odour escapes and/or that liquid seeps in the pit, and whereby damages to the seal arising under an extremely heavy load are optimally excluded on the other hand, even when the frames and lids are made of synthetic material and when the load is more than 12 tons.
the invention concerns a device for sealing pits, consisting of a horizontal frame and cover means fitting in this frame, characterized in that the frame has two concentric ducts which can each contain an amount of liquid; in that the cover means have two ribs on their bottom sides which extend into the concentric ducts as the cover means are applied, whereby the ducts and ribs are made such that two liquid seals are created with an inclusion of air in between which can prevent liquid from entering; in that the outer rib rests in the outer duct, preferably on the bottom thereof; and in that the outer rib serves as a support for at least the part of the cover means which serves as bearing surface.
the above-mentioned construction is advantageous in that the load which is exerted on the bearing surface of the cover means is optimally transferred to the frame, without certain ribs being bent in their seatings and breaking off.
the above-mentioned cover means may hereby consist of a single lid which has at least two ribs on its bottom side which work in conjunction with the above-mentioned concentric ducts, or they may consist of two separate lids placed on top of one another, of which the top lid has a rib on its bottom side which works in conjunction with the outer duct and of which the bottom lid has a rib on its bottom side which works in conjunction with the inner duct.
the device for sealing pits consists of a horizontal frame and cover means fitting in this frame, characterized in that the cover means consist of two lids placed on top of one another; in that the frame has two concentric ducts which can each contain an amount of liquid; and in that the top lid has a rib on its bottom side which extends into the outer duct and in that the bottom lid has a rib on its bottom side which extends into the inner duct, such that an inclusion of air can be created in between the lids which can prevent liquid from entering.
the cover means consist of two lids placed on top of one another; in that the frame has two concentric ducts which can each contain an amount of liquid; and in that the top lid has a rib on its bottom side which extends into the outer duct and in that the bottom lid has a rib on its bottom side which extends into the inner duct, such that an inclusion of air can be created in between the lids which can prevent liquid from entering.
the invention concerns a device 1 for sealing pits, consisting of a horizontal frame 2 and cover means 3 fitting in this frame.
the device 1 is characterized in that the frame 2 has two concentric ducts 4 and 5 which can each contain an amount of liquid 6; in that the cover means 3 have two ribs 7 and 8 on their bottom sides which extend into the concentric ducts 4 and 5 as the cover means 3 are applied, whereby these ducts and ribs are made such that two liquid seals 9 and 10 are created with an inclusion of air 11 in between, which can prevent liquid 6 from entering in the pit; in that the outer rib 7 rests on the bottom 12 of the outer duct 4; and in that the outer rib 7 serves as a support for at least the part of the cover means 3 which serves as bearing surface 13.
the cover means 3 consist of a single lid 14.
the outer rib 7 is preferably situated on the inner edge 15 of the lid 14, such that this lid 14 cannot topple, not even under a very heavy load, and does cannot come out of the frame 2, for example when heavy vehicles drive over it.
the base 16 of the frame 2 preferably extends under the outer rib 7, such that pressure forces are vertically transferred downward from the rib 7 to the construction provided under the frame 2, as a result of which the frame 2 is not under any strain of bending.
the device 1 is preferably also provided with positioning means to position the lid 14, or at least the rib 7 in the frame 2, such that the lid 14, as the pit is sealed, always fits in the same place in the frame 2, and the above-mentioned spaces 17, 18, 19 and 20 are respected.
these positioning means consist of a seating 21 for the bottom edge 22 of the rib 7.
the second rib 8 hangs down entirely freely in the duct 5.
the lid 13 is entirely countersunk in the frame 2.
the frame 2 and the cover means 3, in this case the lid 14, are made of synthetic material, which may be reinforced with glass fibres.
the device 1 according to the invention is advantageous in that water cannot seep in the underlying pit.
a liquid for example rain water
enters the space 17 it will seep through into the space 18.
the water from the space 18 will run over the wall 23 between the ducts 4 and 5 into the duct 5.
an inclusion of air 11 is created.
a counterpressure is created which finally results in a situation as represented in figure 2 whereby the water column in the space 20 is higher than in the space 19.
the pressure which is thus created in the inclusion of air 11 prevents the liquid from flowing any further from the duct 4 into the duct 5, even when the space 17 is entirely filled with liquid.
the ducts 4 and 5 should hereby be suitably dimensioned, whereby the minimum dimensions can be either calculated or determined by experiment.
Figure 3 shows a variant whereby the cover means 3 consist of two lids 24 and 25 situated on top of one another.
the above-mentioned rib 7 is hereby part of the lid 24 and the above-mentioned rib 8 is part of the lid 25.
the lid 25 rest on the inner edge 26 of the frame 2, and there is an air slot between the two lids.
the embodiment of figure 3 is also advantageous in that the space of the inclusion of air 11 is bigger than in the embodiment of figure 2 and in that a downward pressure force is exerted on the lid 25, as a result of which it is pressed onto the inner edge 26.
Another advantage of the embodiment of figure 3 consists in that the liquid 6, as an underpressure is created in the pit, is not sucked inside, as in this case the lid 25 is sucked onto the inner edge 26 and the suction of the liquid 6 is prevented.
the invention also concerns a device 1 which is provided, as represented in figure 3, with two lids 24 and 25, whereby the top lid 24 has a rib 7 which fits in the duct 4, and the bottom lid 25 has a rib 8 which fits in the duct 6, regardless of whether the rib 7 serves as a support or not.
cover means 3 consist of two lids 24 and 25 instead of one single lid 14, all characteristics which are described by means of figure 2 are also valid for the embodiment of figure 3.
