Definitions

  • the invention relates to an emergency drain device for a Water drains with drained area, especially flat roof a drain opening with a water level limit value to the area-determining accumulation device and with a vertical connected to the drain opening Drain pipe.
  • water drains that drain with drain holes in of the surface.
  • the water drains can do this are located freely in the surface, that is to say, flow from all sides be, or the surface formed on lateral boundaries be, for example, as a parapet drain of a flat roof.
  • the Leakage capacity of the water drains is dimensioned so that a certain water retention level should not be exceeded. If the water drains do not provide the required drainage capacity, the water accumulation level on the surface can increase, causing not only impaired the possible accessibility of the area can cause significant static problems can be, namely if the surface on a supporting substructure is mounted, such as for flat roofs and Cover areas on ships is the case.
  • the reduction of the expiry date The normal water drainage can be caused by constipation the water drainage system of the water drains or else the drainage openings of the water drains or any upstream ones Grid caused.
  • the emergency drain device dimensioned so that after reaching the water accumulation limit there is no significant additional accumulation height.
  • the emergency drain device must therefore be as sudden as possible provide a high drainage rate. From constructive and For architectural reasons, this high drainage rate should be a matter of course if possible not through over-sized drain openings and drain pipes can be achieved.
  • the invention is therefore based on the problem, a To design the emergency drain device of the type mentioned at the beginning that a sudden high drainage rate with normal diameters for the drain opening and the vertical Drain pipe is achieved.
  • a container in the flow direction of the drain opening is connected upstream, which has a side wall that up to to a height that is less than the height of the side wall, has at least one inlet opening and above the inlet opening with an airtight lid Forms space.
  • the emergency drain device is based on the effect that the inlet opening when the water accumulation limit value is exceeded in the side wall of the container due to the accumulated Water is sealed airtight, so that the filling of the vertical drain pipe in the container above the Inlet opening forms a negative pressure, which is reinforced Sucking the water from the surface into the container - and with it into the vertical drain pipe - causes.
  • This effect occurs if the inlet opening is only a little above the height of the water accumulation limit value, so that the vacuum effect mentioned quickly when the water accumulation limit is reached "starts" and for an abruptly high water drainage performance that is much higher than a conventional one Gravity flow.
  • the inlet opening can lead to the inlet opening until something extends beyond the level of the water retention limit.
  • the height of the inlet opening should be the water accumulation limit usually by no more than about 1 cm.
  • the inlet opening extends into the or extends below the level of the water retention limit.
  • the inlet opening this will expediently be the other hand extend to the bottom of the side wall of the container.
  • the inlet opening can expediently at the same time the function of an inlet grille to protect against gravel, leaves and similar contaminants when formed from a variety is formed by slots.
  • the slots are convenient directed vertically.
  • the container can be used to facilitate attachment of the container be completed with a floor that is immediately on the Area, or with a preferably corresponding to the accumulation height Distance to the surface can be mountable.
  • the inlet opening is funnel-shaped, preferably a has radially outwardly bent edge to the horizontal.
  • the accumulation device is expediently passed through the mouth opening a pipe section formed, which is preferably immediate opens into the vertical drain pipe.
  • a pipe section formed which is preferably immediate opens into the vertical drain pipe.
  • connection to the vertical drain pipe via a horizontal one Line for example a horizontal manifold to manufacture for several drain openings of the emergency drain device.
  • the damming device then as a kind of weir inside or outside of the container. Is the emergency drain facility arranged at an edge delimiting the surface, a horizontal drain pipe can be passed through the edge and a damming device forming over the surface have uplifting level.
  • FIG. 1 shows a vertical section through an inventive Emergency drain device that is sealed by a sealed surface 1 a flat roof is passed through.

  • the height of the inlet opening selected in this exemplary embodiment 15 corresponds to the water accumulation limit value H at which the emergency drain device should take effect and via which the pent-up Water must not rise significantly to avoid static Risk of overloading.
  • Edge 7 is arranged somewhat higher than the upper edge of the inlet opening 15.
  • the water accumulating on the roof surface 1 provides for a rise in the water level within the container 8. This also applies because of the principle of the communicating tubes then when the water level over the height of the slots 16 of the Inlet opening 15 rises. Is that due to the height of the drain opening 6 certain water accumulation limit value H is reached the container 8 with airtight security, because the vertical slots 16 of the inlet opening 15 filled with water are.
  • the water accumulation limit value H arises in this embodiment by a within the Container 8 provided, circumferential cylindrical wall 17th Only when the water level on the sealed surface 1 is the height of the cylindrical wall 17, there may be a filling of the vertical drain pipe 2 and to form the vacuum effect in the closed above the inlet openings 15 Container 8 come.
