Definitions
- the present invention relates to a method for delayed drainage of the meteor or rainwater from roofs and surfaces with backflow capacity.
- the invention further relates to a device for delayed outflow of the meteor or rain water from roofs and surfaces with backflow capacity.
- the line cross sections of the lines leading from the roof to the sewage system are dimensioned correspondingly small, so that only the prescribed permissible quantity can flow off.
- the object of the invention is. to create a method and a device which, with simple means, make it possible to adapt the amount of water flowing to the drain lines to the capacity of the sewer network and / or the sewage treatment plant and to the backflow capacity of the building. Another object is to design the device in such a way that its safe function is not dependent on any further parameters.
- the maximum amount that flows away can be precisely determined. Amounts of water that are below their maximum capacity can always run off unhindered. If the amount flowing in exceeds the capacity of the throttle element, there is a backlog on the roof. If the maximum overflow capacity of the roof is exceeded, the additional water flowing in can be drained off by bypassing the throttle by means of an emergency drain pipe arranged in the throttle or separately.
- the flow restrictor at the inlet of the drain pipe can and must be arranged directly in the level of the roof or elevated must not be placed in a recessed pot which can weaken the roof or which can lead to great difficulties when retrofitted.
- the drain pipes inside the house can be routed to the most favorable locations on site and their cross sections only have to be adapted to the highest possible amount of water.
- the vortex throttle is insensitive to blockages and can be cleaned easily if contaminants prevent a regulated process.
- the costs for the delayed outflow of the meteor water are low, since no lengthy calculations of the pipe cross-sections and expensive laying of the pipes within the building are necessary.
- FIG. 1 shows a section of a flat roof with retention accumulation capacity and with a discharge throttle.
- Figure 2 shows a section along line 11-11 in Figure 3 of the device for delayed drainage of the roof water.
- Figure 3 shows a cross section along line 1II-III of the device in Figure 2.

- FIG. 8 shows a view of the vortex throttle in FIG. 7
- FIG. 9 shows a horizontal cross section through an alternative design of the vortex throttle made of bent sheet metal parts
- FIG. 10 shows a view of the vortex throttle in FIG. 8,
- FIG. 11 shows a vortex throttle with tangential inlets in the same direction, without an emergency overflow through the vortex throttle
- FIG. 12 shows a vortex throttle with two in the same direction inlets with one emergency overflow
- FIG. 13 shows a vortex throttle as in FIG. 12 with a siphon-like one
- FIG. 14 shows a vortex throttle with an emergency overflow covered by an immersion body
- FIG. 15 shows a cross section through a built-in adapter
- Figure 16 is a perspective view of a vortex throttle
- Figure 17 is a floor plan of a vortex throttle with radial and tangential inlet (tangential inlet in broken
- FIG. 18 shows a section of a flat roof with a permanent accumulation and a vertically arranged vortex throttle
- FIG. 19 shows an alternative embodiment of a horizontally arranged one
- Vortex choke for a flat roof with permanent accumulation Vortex choke for a flat roof with permanent accumulation.
- the reference number 1 in FIG. 1 shows a detail of a top part of a building with a flat roof 3, which has laterally raised wall sections 5 to form a retention basin 7 for the backflow of rain water temporarily retained during a rain event.
- the structure of the flat roof 3 is not shown in detail since it is not the subject of this invention.
- the inclination of the roof 3, which causes the water that collects there to flow to a drain 9. from which it can be fed through a pipeline 11, which usually runs in the building 10, to a sewer line (not shown) or an infiltration laid in the ground.
- the drain 9 is flush with the upper edge of the roof in the examples according to FIGS. 1 to 5, so that the roof 3 in the area of the drain 9 is not weakened by a collecting basin 13, as shown in the example according to FIG. 6 .
- a vortex throttle 17 is placed, which in the example according to FIGS. 1 to 3 consists of two plates 19 and 21 arranged parallel to one another, the two plates 19, 21 being formed by two arcuate ones vertically standing baffles 23 and 25 are interconnected.
- the two plates 23 and 25 each have a quarter arc 25 and 27 and then essentially each have a rectilinear section.
- the gap-shaped openings 33 and the two plates 19 and 21 form the inlet for the inflow of water to the pipeline 11, which is located in the center of the vortex throttle 17 and connects to a pipe socket 16.
- a pipe socket 35 of height h can be placed, which forms a direct connection into the interior of the vortex throttle 17 and coaxially with the upper end 15 of the pipeline 11 lies.
- the upper edge 37 of the pipe socket 35 is at the height h max ., which corresponds to the maximum accumulation height in the retention basin 7.
- a semicircular pipe piece 38 as shown for example in FIGS. 13 and 19, or a diving bell 40 as shown, can be placed on the upper end of the pipe socket 35 is shown, for example, in FIG. 14.
- the diving bell 40 has a jacket 42 and a cover section 44. Between the upper end of the tube 35 and the lid section 44, a gap corresponding at least to the cross section of the tube 35 is kept open. Contamination floating on the water surface is retained by the jacket surface 42 and the water can flow under the jacket 42 to the pipeline 35.
- the vortex throttle 17 can be made of steel or plastic.
- the top plate 19. e.g. by loosening wing nuts 39, which are lifted off on corresponding bolts which pass through the plate 19 and are attached to the vertical plates 23 and 25, in order to enable cleaning of the interior of the vortex throttle 17.
- baffles 24, 26 which are bent once or several times or welded together from sections can also be connected to the two plates 19 and 21 in the manner described.
- the guide plates 24 are bent twice by folding and have straight sections 24, 26.
- the openings 33 can be fixed or, as shown in FIG. 2, variable (not shown). With a small inflow of water, ie with light rain, all of the inflowing water can flow continuously through the openings 33 into the interior of the vortex throttle 17 and from there through the line 11 into the sewage system.
- a pipe section 41 ending at the same height can of course also be connected directly to the pipe 11 or an additional pipe leading to the sewage system (no fig. ) be connected.
- the entire vortex throttle 17 is preferably surrounded by a removable grating 43.
- the grid 43 can completely surround the vortex throttle 17 laterally and at the top (FIG. 1) or be designed as a round or rectangular basket 48 open at the top (FIG. 15).
- one for the one to be discharged can have a small maximum discharge quantity
- the amount of water in the vortex throttle 17, which is too large, at least one of the openings 33 is closed by a cover (not shown) or can be reduced or closed by the adjustable slide 34 (FIG. 2).
- a cylindrical vortex throttle 45 of known construction is used, such as is used in rain pools in which the water enters through a tangentially opening access opening 47 and can flow out throttled through the central discharge opening 49.
- the mode of operation of the vortex chokes 45 shown in FIGS. 4 to 6 is identical to that shown in FIGS. 1 to 3.
- These vortex chokes 45 can also be protected against contamination by a basket or a grid 43.
- the vortex chokes 17, 45 can also be used directly in a gravel bed on the flat roof 3.
- vortex chokes 17,45 placed directly on the surface of the flat roof 3, these can of course also be arranged within a sump 51 sunk in the flat roof 3 (FIG. 6).
- a vortex throttle 45 as shown in FIG. 11, can also be used for a temporary backflow of rainwater which flows in a larger quantity than can be taken up by the sewage treatment plant.
- This vortex choke 45 has no through it running emergency overflow, but this must be provided independently and elsewhere on the roof.
- emergency overflow lines 35 are provided which are arranged coaxially with the throttle 45.
- the emergency overflow line is open at the top.
- a semicircular pipe bend 52 is placed on the end of the pipe socket 35 of the emergency overflow line, which prevents that contaminants floating on the surface of the dammed up water get into the emergency overflow line and can block it.
- the vortex throttle 77 shown schematically in FIG. 16 has an inlet 79 which opens into the upper cover surface.
- This vortex throttle 77 can either be used in a sump, as shown in FIG. 6, or on a roof with a permanent backflow of height a.
- the vortex throttle 69 shown in FIG. 17 can be provided with a radial inlet connection 71 or additionally have a tangential inlet 73.
- the tangential inlet 73 can be higher than the inlet nozzle 71. This makes it possible, if the lower inlet 71 is blocked, as an emergency inlet Throttle characteristics to act.
- a strainer 75 can be placed in front.
- the colander 75 consists of a tubular section, which is closed on the end side, and is made of perforated sheet metal or of a grid-like material.
- the vortex throttle 69 shown in FIG. 17 is used analogously to the others already described.
- the outlet-side opening of the vortex throttle 55 is arranged above the hote h3.
- the vertically arranged vortex throttle 55 can have a configuration corresponding to the vortex throttle 45 shown in FIG. 4, the water inlet opening 47 being located below the knot hn.
- a vortex throttle 17, as shown in FIGS. 2.7, 8 and 9, could also be used if one of the two inflow openings, namely the one at the top, is closed.
- the emergency transfer line 35 is arranged in the vertical extension of the pipeline 11 and can have a hood or diving bell 40, as described and shown in FIG. 14, to prevent the entry of floating contaminants.
- a baffle 67 can also be arranged around the inlet 47 of the vortex throttle 55.
- the baffle 67 consists of vertically positioned metal sheets or plastic plates which prevent the entry of floating impurities to the water inlet opening 47.
- the water collecting on the roof 3 can flow unrestricted through the immersed access opening 47 into the pipeline 11 and from there to the sewage system.
- water can be supplied to the pipeline 11 unthrottled through the emergency overflow line 35.
- the vortex throttle 55 or its outlet-side opening 47 lies on the hote h3, which corresponds to the intended height of the continuous congestion. If the water level rises further, as long as it does not exceed h4, the water can flow unrestricted into the pipeline 1 1. If the hote h4 is exceeded, the effect of the vortex throttle 55 begins. ie the water flowing from now on to the vortex throttle 55 is discharged in the amount determined by the formation of the vortex throttle 55, which cannot be exceeded. With a further climb over the Kote h ma ⁇ , the water can flow off via the emergency overflow line. The front end 59 of the emergency transfer line 35, which is immersed in the water level h ma , in turn prevents floating impurities from entering the pipeline 11 and blocking it.
- vortex throttle 55 in the embodiment of the invention according to FIG. 19 is arranged on the level of the roof 3, its mode of operation corresponds to that in FIG. 1.
