    The invention relates to a fire protection system for a drainage system of a surface or road o. The like. In such drainage systems, the safety problem that after accidents or fires burning fluids can flow into the drainage system and so can transport a punctual fire, so that this area spreads.
    From DE-U-202 00 625 a fire protection system is known in which a fire protection cartridge is arranged in a sequence. In case of fire, the cartridge or its contents foams up and thus prevents the further flow of the burning fluid. The purpose of this fire protection device is the isolation of the fire and the simultaneous prevention of fire spread on underneath or overlying floors. The disadvantage here is the fact that the burning fluid can no longer flow, so that the fire nourishing fuel remains at the source of fire.
    Proceeding from this, the present invention seeks to design a fire protection system so that a spread of a punctual fire on the drainage system is effectively prevented. This object is achieved by the combination of features of claim 1 by simple means in an inventive manner. The dependent claims contain in part expedient and in part self-inventive developments of the invention.
    The erfindungsmäß fire protection system is arranged in a consisting of one or more drainage pipes drainage system. In each of these lines run-offs open at regular or irregular intervals. In particular, such an arrangement of roadways is known, on which edges at certain intervals drainage shafts are arranged. Above all, the invention is suitable for fire-protected drainage of tunnel lanes, in which the drainage lines due to the fluidic conditions in the tunnel burning fluids forward very quickly, so spread especially in tunnels fires on the drainage pipes unusually fast.
    The solution of the problem consists in a structurally very simple and therefore inventive integration of the fire protection system in the existing downcomers. In each downcomer, a drain pipe is first introduced. This drain pipe protrudes with its inlet end vertically into the downcomer. The end of the drain pipe facing away from the inlet end opens into the bottom or a side wall of the downcomer. The vertical projecting into the downcomer drainpipe forms as it were a standpipe. About the inlet end of the inlet end of the drain pipe, a bell-shaped hood is slipped. The slipped hood leaves both a radial gap between their hood inner shell on the one hand and the Ablaufrohrauraußenmantel on the other hand free. Also, the inside of the top surface of the hood is not located on the opening edge of the inlet opening, but is also arranged at a distance from the opening edge of the inlet opening to release here also a drain gap for the fluid to be discharged.
    The fluid to be discharged first runs into the downcomer and fills it up to the height of the opening edge of the inlet opening of the drain pipe. Only when the liquid level of the fluid to be discharged exceeds the height level of the opening edge, the fluid to be discharged flows through the inlet opening into the drain pipe.
    Due to the patch on the drainage bell-shaped hood, the fluid does not flow directly into the drain pipe, but previously passed the drain gap formed between the hood and the inlet end of the drain pipe. If such a large amount of fluid introduced into the downcomer that the current fluid level projects beyond the height of the drain pipe, the fluid according to the law of communicating tubes is pumped even with overpressure through the flow gap as it were. For this purpose, the cross-sectional area of the outlet gap 1/15 is particularly dimensioned so that it is equal to or greater than the free cross-sectional area of the drain pipe. Thus, the amount of liquid that can be transported away via the discharge pipe continues to depend on the cross-sectional area of the discharge pipe, but not on the cross-sectional area of the discharge gap.
    While a sufficient amount of oxygen is present in the downcomer to keep a burning fluid from burning, the supply of oxygen to the fluid is abruptly interrupted as a result of the labyrinthine flow gap formed by the hood and the drain tube shell. Due to this abrupt interruption of the oxygen supply, the flame holding the fluid burning is stifled. Replenishment of oxygen to maintain the burning process from the drainpipe ago is not possible because the combustion gases of the burning fluid accumulate in the hood. As a result, a slight overpressure builds up in the hood. Thus, rising in the drain pipe colder oxygen-rich air is forced back into the drain pipe due to pressure equalization.
    The fluid is removed via the drainage line without burning further. As a result of the suffocation of the flame due to the lack of oxygen, a spreading of the punctual fire is effectively prevented by the fluid passed through the drainage line.
    With the invention, it is possible to effectively prevent the spread of fire over leaking burning liquids without the flow of liquids must be stopped via the drainage pipe. Damage to the often made of a plastic, in particular made of PVC, drainage pipe is thus safely avoided. Thus, after the occurrence of a punctual fire no costly renovation work to replace or repair the drainage pipe is necessary. Due to the removal of excess combustible fluid in addition, the duration of the punctual fire is reduced, if from a certain point no more flammable fluid flows.
    In addition, the hood outer wall acts as a baffle. In other words, impurities floating on the fluid surface or an oil film formed on the fluid surface can not enter the drainpipe from the drainage gap. Thus, a rough pre-cleaning of the discharged from the drain pipe fluid.
    The invention is therefore particularly suitable for use in drainage systems of traffic tunnels and enclosures and on operating areas of the process industry, in particular the chemical industry, refineries or the like.
    In a typical embodiment, the drainpipe has a diameter of DN100 and the hood has a diameter of DN200. The diameter of the discharge pipe leading away from the downcomer lies at a diameter of DN150. With a downcomer of these dimensions, the swallowing capacity is about 15 l / s. In other words, 15 l of fluid can be diverted from the downcomer per second.
    According to the teaching of claim 3, it is advantageous to design the flow gap between Haubenin nenmantel and Ablaufrohraußenmantel as a circumferential gap with preferably constant gap width. In this way, a comparatively large amount of fluid can be transported away while maintaining the interruption of the oxygen supply in the outlet gap.
    Claim 4 relates to an embodiment of the invention with a dual function of the hood. In this embodiment, the hood is arranged movable relative to the drain pipe. The hood is displaced in this way in the vertical direction between an open position and a closed position back and forth. The open position is unchanged from the functional position of the rigid variant of the invention with respect to the drain pipe stationary fixed hood. For conversion to its closed position, the hood is moved in the vertical direction on the drain pipe so far toward the bottom of the downcomer until arranged on the inside of the hood closure cap or the top surface of the hood on istifreicisiseies pstestarct AT 13 081 Ul 2013-05-15 firmly rests the opening edge of the inlet opening and closes the inlet opening so tightly. In order to ensure the automatic liquid drainage when the drainpipe is closed, the hood is designed so that it swims upwards in the downcomer as the liquid level rises. Thus, the flow gap between the top surface of the hood and the opening edge of the inlet opening is released again, so that the fluid can escape through the flow gap unhindered. The hood is in this case secured to the drain pipe so that a floating of the hood beyond the open position, in which the flow gap is completely released, effectively prevented.
    The fluid drains below the burning fluid surface. If the liquid level drops, the cover arranged on the hood inner shell closes the inlet opening of the drain pipe again. A penetration of burning fluid is thus safely avoided when the liquid level drops.
    The claims 5 and 6 relate to two different arrangement possibilities of the drain pipe in the downcomer. In the embodiment according to claim 5, the drain pipe opens into the bottom of the downcomer. It is therefore a vertically extending, strictly cylindrical pipe section. The embodiment according to claim 6 relates to an arcuate pipe section, which opens into a side wall of the downcomer. Both variants are well suited for insertion into existing drain lines in the bottom or a side wall of the drain shaft. According to the teaching of claim 7, finally, the annular space between the Ablaufrohrauraumantel and the associated mouth opening in the bottom or in the side wall is additionally secured by an annular seal. The ring seal can also compensate for dimensional accuracy or other tolerance errors. To further secure the annulus seal at this interface between the drain pipe and the actual drainage pipe, the additional clamping plates are provided according to claim 8.
    The claims 9 and 10 relate to an alternative embodiment of the fixation of the drain pipes at the bottom or the side wall of the downcomer. In this case, a mounting flange is arranged on the drain pipe end in the region of the outlet opening. With the help of this mounting flange, the drain pipe can be fixed either on the floor or on a side wall of the drainage shaft with several screws. In a further development is proposed according to claim 10, to switch between the mounting flange and the mounting flange holding the bottom or the mounting flange holding side wall between a gap seal. This variant also prevents unwanted escape of the fluid outside of the drain pipe.
    The variants according to claims 5 to 10 are also very suitable for retrofitting existing downcomers with the inventive fire protection.
    In claim 11, finally, a variant for fixing the drain pipe in the bottom or a side wall of the downcomer is proposed, in which the drain pipe embedded in the bottom or the side wall form-fit, in particular is concreted. The positive embedding takes place during the manufacture or prefabrication of the downcomer. When form-fitting molding of the drain pipe in the downcomer, it is expedient to provide a circumferential wall ring on the drain pipe. The encircling wall ring jumps radially outward in the manner of a rotating disc out of the drain tube outer jacket. This radially projecting disc prevents formation or erosion of a gap between the Ablaufrohraumantelmantel and the drainage tube embedding material, in particular concrete. In particular, due to the capillary action of the water, it can happen occasionally occurrence that unintentional passageways between the drain rohrau ßenmantel and form the drainpipe embedding material. This channel formation is effectively prevented due to acting as a blocking plate wall ring.
    Claim 12 finally includes an embodiment of the invention with a flow direction upstream of the drain pipe sludge bucket in the downcomer. Such a sludge bucket favors keeping the downcomer clean because leaves, mud and other contaminants are collected in the sludge bucket. In order to keep the discharge shaft clean, the end grate must be lifted off the drainage shaft, and then the 15/15 Fetishi AT13 081 U1 2013-05-15
    Slurry buckets are lifted out, emptied and cleaned. In addition, the sludge bucket throttles and evenifies the amount of liquid supplied to the downcomer. As a result, the risk of a strong turbulence of the fluid before it enters the outlet gap, combined with the possible discharge of a local fire source via the outlet gap into the drain tube, is low.
    In this embodiment, a certain amount of water always collects first in the sludge bucket, so that the actual downcomer is dry inside. In these conditions, it is then desirable that the drain pipe is closed by means of the hood. The hood then has the function of an odor trap. Finally, the invention also favors the cleanliness of the drainage shaft. Due to the two-fold reversal of direction and the reduction of the flow velocity of the fluid, impurities in the fluid, in particular suspended matter and solids contained in the fluid, can penetrate into the drainpipe only to a limited extent due to the outlet gap. The impurities are deposited outside the drainpipe at the bottom of the downcomer, where they can easily be skimmed off or sucked off.
    Based on the embodiments listed below, the invention with further advantages and features is further described. 1 shows a drainage system, FIGS. 2 to 3 a first downcomer, FIGS. 4 to 5 a second downcomer, FIG. 6 a side wall of a downcomer, [0028] FIG. 7 shows a bottom of a further downcomer, and [0029] FIGS. 8 to 9 show the side walls of two further downcomers.
    According to FIG. 1, a drainage system 1 has a drainage channel 3 formed in the longitudinal direction 2. The drainage system 1 is shown in a longitudinal section 2 cut side view. The gutter 3 is arranged on the edge of a roadway, not shown in FIG. The drainage system 1 has in the longitudinal direction 2 a plurality of spaced-apart drainage shafts 4. The downcomers 4 break through the gutter 3 and lead in the vertical direction 5 in the ground substantially. Each downcomer 4 is connected by means of a drain line 6 with a longitudinal direction 2 extending drainage line 7. A, for example, due to a precipitate on the roadway accumulating liquid is passed through the gutter 3, the drain chutes 4 and the drain lines 6 to the drainage line 7 and discharged from this.
    In Fig. 1, only a section of the gutter 3 is shown with three downcomers 4. In this case, the left and right downcomer 4 are designed in a first variant described in FIGS. 2 and 3, and the middle downcomer 4 in a second variant described in FIGS. 4 and 5.
    Fig. 2 shows the first variant of the downcomer 4. The downcomer 4 is a downwardly from the drainage channel 3 from essentially in the vertical direction 5 extending downward and closed cuboid hollow body. The hollow body has four side walls 8 and a bottom 9. He is poured from a concrete. On one of the side walls 8 near the bottom 9, a circular mouth opening 10 is arranged. In this mouth opening 10, the end of the drain line 6 is attached. The drain line 6 in turn leads to the drainage line 7, as shown in FIG. In the downcomer 4, a drain pipe 11 opens. The drain pipe 11 is designed as a 90 ° elbow. It protrudes with its inlet end 12 in the vertical direction 5 into the downcomer 4. The outlet end 12 facing away from the drain end 13 opens with its outlet opening 13 'in the drain line 6. The drain pipe 11 is held with its Ablaufrohraußenmantel 14 of an inserted into the end of the drain line 6 annulus seal 15. The annular space seal 15 seals the ring formed between the drainage pipe shell 14 and the inside of the drainage pipe 11 from the room. The annular space seal 15 is fixed in position by means of clamping plates 16.
    About the inlet end 12 final inlet opening 17 of the drain pipe 11, a bell-shaped hood 18 is slipped. The hood 18 is designed as a hollow cylinder which is closed in the vertical direction 5 upwards by a top surface 19 designed as a dished bottom. At the outlet rohrau ßenmantel 14 is in the region of the inlet end 12 of the drain pipe 11 in the vertical direction 5 upwardly extending and the hood 18 at its free end by cross-retaining pin 20 is attached. The retaining bolt 20 connects via a wing nut 21, the hood 18 releasably connected to the inlet end 12. In this way, a Beab-standing the hood 18 to the inlet end 12 of the drain pipe 11 is reached. In this case, a drain gap 25 is formed both between a portion of the hood inner shell 22 and the Ablaufrohraußenßenmantel 14 and between the inside 23 of the top surface 19 of the hood 18 and the opening edge 24 of the inlet opening 17. This outlet gap 25 has the geometry of an annular gap with a constant gap width in the area in which the hood 18 covers the downpipe 12.
    Directly below the gutter 3 is a penetrated by recesses 26 and the entire cross section of the downcomer 4 obstructing sludge bucket 27 is arranged. For the discharge of a fluid, the interior of the downcomer 4 forms a fluid collection chamber 28. The fluid taken up by the fluid collection chamber 28 may also be a burning liquid such as gasoline, due to an accident occurring on the roadway in the downcomer 4 and thus in the Fluid collection chamber 28 enters. Coarse impurities contained in the fluid, such as leaves, stones or the like, are collected in the sludge bucket 27. The sludge bucket 27 also limits the amount of fluid flowing to the fluid collection chamber 28 per unit time. The fluid fills up the fluid collection chamber 28 up to the height of the opening edge 24 of the inlet opening 17 of the drainage pipe 11. If the liquid level of the fluid exceeds the height level of the opening edge 24, the fluid flows through the inlet opening 17 into the drainage pipe 11 and is led via the drainage line 6 to the drainage line 7.
    The fluid is not directed directly, but via the detour of the flow gap 25 in the drain pipe 11. Therefore, there are two effects. On the one hand, a discharge of the fluid takes place with a time delay only when the liquid level of the fluid is above the height level of the opening edge 24. As a result, particulate matter contained in the fluid, which has passed through the recesses 26 of the sludge pail 27, settles on the bottom 9 of the downcomer 4 due to a slowing down of the flow velocity of the fluid. The suspended matter thus does not reach the drain line 6.
    On the other hand, in the outlet gap 25, the oxygen supply to the fluid is interrupted abruptly. If it is a burning fluid, the flame holding the fluid burning is safely smothered. In this way it is ensured that the burning fluid is not entered into the drain line 6. Rather, it comes at best to a local fire in the downcomer 4. An extension of the fire is thus effectively avoided.
    The sludge bucket 27 causes a throttling and homogenization of the downcomer 4 supplied amount of liquid. This avoids a surge-like entry of the fluid into the outlet gap 25. Fire pockets trapped in air bubbles in the fluid can thus not enter the drainage pipe 6.
    So that the drain pipe 11 and the hood 18 can withstand a fire, they are made of a heat-resistant stainless steel. This stainless steel is for example V4A. V4A is not only heat resistant, but also resistant to corrosion and aging. Also all other components, such as the retaining bolts 21 or the clamping plates 16, which may be exposed to fire, are advantageously made of such a stainless steel. All components can be pickled and passivated as additional protection. The wing nut 21 allows rapid disassembly of the hood 18 for inspection purposes or for flushing the drain pipe 6. 5/15
    Fig. 3 shows the downcomer according to arrow III in Fig. 2 again seen from the side of the drain pipe 6 ago. Also visible is a pipe flange 29, via which the drain line 6 can be screwed either to another pipe section of the drain line 6 or to the drainage line 7. This pipe flange 29 is not shown in FIG. 2.
    Fig. 4 shows in a longitudinal section in the vertical direction 5, the second variant of the downcomer 4 of Fig. 1. Fig. 5 shows the downcomer of Fig. 4 in a cross section transverse to the vertical direction 5 according to the in Fig. 4 drawn Section plane VV. The upper section of the downcomer with the sludge bucket to be seen in FIG. 1 is not shown in FIGS. 4 and 5. The operation of the downcomer 4 shown in FIGS. 4 and 5 substantially corresponds to the variant shown in FIGS. 2 and 3. It is therefore only discussed the differences to this variant.
    The drain line 6 is arranged centrally in the bottom 9 of the downcomer 4 in a mouth opening 10. The drain pipe 11 is formed as a straight pipe piece extending in the vertical direction 5. It is like the drain pipe in Figs. 2 and 3 held by an annulus seal 15 in the drain line 6 and sealed against it. The hood 18 is arranged opposite the drain pipe 11 in the vertical direction 5 movable. For this purpose, the hood 18 has on its outside three guide tabs 31 arranged in the radial direction 30. Furthermore, a stud holder 32 is attached to the inlet end 12 of the drain pipe 11 at Ablaufrohrauraumantel. The bolt holder 32 is embodied as a bolt circle welded onto the drain pipe outside jacket, which has three retaining tabs 34 projecting in the radial direction 30. At each retaining tab 34, a guide pin 35 is attached end. Each guide pin 35 passes through an inserted into a guide plate 31 recess in a guide sleeve inserted into the recess 36. At the vertically upward of the retaining tab 34 opposite side, each guide pin 35 held by a wing nut 21, pushed onto the guide pin 35 End stop 37 on. In the area of the guide lugs 31, a closure cover 38, which is designed as a circular disk and extends over the entire hood cross-section, is fastened to the hood inner casing 22. This closure cap 38 is in the closed position of the hood 18 on a on the opening edge 24 arranged around seal 40. As a result, it closes the inlet opening 17 and seals it. The seal 40 is designed as a plug-on rubber seal which receives the opening edge 24 in its interior.
    Collects now fluid in the fluid collection chamber 28, so from a certain liquid level, the hood 18 is lifted by buoyancy according to the Archimedean principle in the vertical direction 5 upwards. If further fluid flows in, the hood 18 is lifted up to its open position shown in dashed lines in FIG. 4. This open position is predetermined by the three end stops 37 of the three guide pins 35.
    If the downcomer 4 is acted upon by a burning fluid, the hood 18 is raised in the vertical direction 5 and the closure lid 38 is the inlet opening 17 of the drain pipe 6 free. The fluid drains below its burning surface. If the liquid level drops again, the hood 18 moves in the vertical direction 5 towards the bottom 9 of the downcomer 9. The closure cap 38 closes the inlet opening 17 again. This ensures that no burning fluid penetrates into the drain pipe 6.
    Since the hood 18 must first be lifted for draining the fluid by means of buoyancy, the flow of the fluid from the fluid collection chamber 28 with respect to the downcomer described in FIGS. 2 and 3 is slowed down and delayed. Therefore, the variant with the movably mounted hood 18 is also suitable for a downcomer 4, which has no sludge bucket 27 upstream of the fluid collection chamber 28 for throttling the amount of liquid supplied to the fluid collection chamber 28.
    The inlet end 12 cross hood 18 also prevents coarse contaminants, such as branches or the like, between the cap 38 and the seal 40 are clamped and affect the sealing effect of the cap 38. The total of three wing nuts 21 allow easy disassembly of the hood 18 to 6/15

    öseirsk'hkhei Patent Office AT 13 081 Ul 2013-05-15 Maintenance purposes. Fig. 6 shows a side wall 8 of a downcomer 4, in which a discharge line 6 is fixed in a mouth opening 10. In FIGS. 6 to 9, the drain line 11 in each case continues to be thought to continue into the fluid interior space 28 in such a way that its inlet end 12 extends in the vertical direction 5 with the hood 18 arranged thereon. In the interior of the drain line 6, a concentric annular space seal 15 is arranged, which is held by means of two executed as a bolt holes clamping plates in position at the end of the drain line 6. In this annulus seal 15, the drain pipe 11 is inserted with its discharge end 13 and fixed and held by the annulus seal 15. The annular space formed between the drain outside 14 of the drain pipe 11 and the inside of the drain line 11 is thus effectively sealed. By means of the annular space seal 15, a drain pipe 11 can be retrofitted with attached hood 18 in an existing downcomer. Fig. 7 shows a bottom 9 of a downcomer 4 with a used in a mouth opening 10 in the bottom 9 drain line 6. From the fluid interior 28 of the downcomer 4 ago a drain pipe 11 is attached to the bottom 9. The attachment of the drain pipe 11 via a at its outlet end 13 at the outlet rohrau ßenmantel 14 welded mounting flange 41. The mounting flange 41 is screwed by means of retaining dowels 42 to the bottom 9. In this case, a gap seal 43 is clamped between the mounting flange 41 and the bottom 9. Even with this embodiment, a drain pipe 11 with a hood 18 arranged thereon can be retrofitted in an easy way into an existing downcomer. The gap seal 43 prevents creepage currents arising at the material transition between the bottom 9 and the drain line 6 by capillary action along the outer jacket of the drain line 6. FIG. 8 shows a side wall 8 of a drainage shaft 4 which is cast from concrete. The drain pipe 11 is poured into the side wall 8 and is held in a form-fitting manner by the surrounding side wall 8. In this case, the drain pipe 11 has a circumferential wall ring 44 which is welded at the outlet rohrau ßenmantel 14. The wall ring 44 prevents leakage currents, which could otherwise leave the fluid collection chamber 28 at the transition between the Ablaufrohraußenmantel and the side wall 8 without being discharged through the drain line 6. According to FIG. 9, the side walls 8 and the bottom 9 of the downcomer 4 can also be made of a steel. Here, again, a stainless steel, such as V4A is suitable. In this case, the drain pipe 11 can be fixed in a simple manner in a recess introduced into the side wall 8 'by a weld seam along the outer jacket 14. Claims 1.
