Mud bucket with amphibian exit

Abstract

Mud buckets with amphibian exit are characterized by this: that one or more side walls of the mud bucket have a hole structure that allows amphibians to exit the mud bucket.

Description

Technical Field: Dewatering Plants, Amphibian ProtectionPrior ArtThe sludge bucket (also sludge catch bucket or slot bucket) is a coarse dirt insert which catches coarse materials (such as leaves, gravel, etc.) in the roadway run-off (also Gully) so that they do not pass into the shaft and into the channel system. The sludge buckets must be emptied regularly, being lifted out and the coarse materials being supplied to the disposal.Sludge buckets have different shapes and sizes, depending on the shaft diameters and depths and the quantity of coarse materials obtained. Common to these is that they have holes and slots, the function of which is to allow water to pass through, so that the drainage function of the road run-off is maintained despite coarse dirt filters.Frequently used models are designed according to the standard DIN 4052 concrete parts and buckets for road operations.Problem situationMany amphibies and other small animals pass through the shaft grids into the road processes. If a sludge bucket is present, they are initially collected by it. Amphibies can only rarely be climbing the sludge buckets. They often dry therein or pass through the slots and holes into the shaft and then partly into the channel system. It is believed that hundreds of thousands to millions of amphibies are used annually to end up in the drainage system.At neuralgic points, such as at amphibian draw points or in the vicinity of leaf waters, egress aids for amphibians are therefore repeatedly used in shafts, for example in the form of a perforated sheet metal rail. These exit aids can, however, present a problem during maintenance and only act if they are correctly reinserted.The technical design of conventional sludge buckets has not yet taken amphibies into account. The walls do not offer a structure which can be made to be elaccid for amphibies. If they are still able to climb up, they will likely pass to slits and holes through which they will slip and enter the well.The invention set forth in the claims is thus based on the problem of providing a sludge bucket which is adapted to be harvested for amphibies and reduces the risk of a passage into the shaft.Problem Solution / InventionThis problem is solved by the features set forth in claims 1-7.The invention consists in a sludge bucket having a new hole structure on at least one side wall which can climb the amphibies and which thus enables them to leave the sludge bucket, and a new arrangement of the holes and slots which makes it difficult for amphibies to pass through them and enter the shaft. The filtering function of the sludge eliminator is thereby equally obtained.The other shape of the sludge buckets can remain or, as described in claim 6, can be modified in an advantageous embodiment to the effect that one or more side walls with a hole structure have a smaller gradient than the other walls.An embodiment of the invention will be explained with reference to FIGS. 1 to 10. The following are shown: FIGS. 1 and 2 show a sludge bucket with an integrated hole structure on two opposite side walls with a smaller pitch and specifically arranged holes / slots on the other walls. FIG. 3 is a top view of the hole structure on two opposite side walls FIG. 4 is a partial side view of the hole structure FIG. 5 is a partial side view of the specifically arranged holes / slots FIG. 6 shows a top view of the hole structure on a side wall with a smaller pitch FIG. 7 is a partial side view of specifically arranged holes / slots in a slurry bucket having a lower pitch sidewall FIGS. 8 to 10 show a sludge bucket with an integrated hole structure on a side wall with a smaller pitch and specifically arranged holes / slots on the other wallsThe figures show the hole structure 1 which can be harvested by amphibians. The maximum hole size described in the claims is intended to prevent amphibies from slipping through the holes. The holes are arranged in a grid structure which comprises a minimum width and extends almost from the bucket bottom to the upper edge of the sludge bucket. From the upper edge of the sludge bucket the amphibies can climb independently through the shaft grid into the open air.The hole structure is advantageously integrated on side walls which have a smaller pitch 4 than the other walls. The side walls with a perforated structure are likewise advantageously situated opposite one another so that the amphibies find their outward emergence more quickly when they run along the bucket base.Larger holes 2 and any slits 3 which ensure the dewatering function are arranged so that the amphibies reach them only with difficulty. The distance of these holes and slits from the integrated hole structure is at least 50 mm for the same reason. Overall, at least the same flow rate of rainwater as in conventional ones should be able to flow out through the sludge bucket into the shaft.AdvantagesThe invention allows amphibies to leave the sludge bucket directly and makes them difficult to enter the well. It only partially changes the shape and configuration of conventional sludge buckets, so that they continue to fulfil their previous function of coarse soil separation. With the additional function of the integrated amphibious exit, amphibious protection on existing drainage systems can be realized more easily and over a greater area. Also, the emptying of the sludge collectors and the shaft maintenance are not affected by the invention. The sludge bucket with integrated amphibian egress can thus be inserted into any well that previously contained a conventional one with equal maintenance.Overall, roughly estimated up to 10% of the drainage wells are affected by amphibian furnish. Particular potential for use is especially in the vicinity of forest and green spaces, at boiling edges, in the vicinity of bodies of water or at amphibian points of traction.LIST OF REFERENCE CHARACTERS1 Hole structure 2 Holes 3 Slots 4 Side walls with a smaller pitch
