Definitions

  • the present invention relates to a rainwater relief system with a rain overflow basin and a retention floor filter.
  • the rain overflow basin is used first a so-called partition structure upstream, which a Has collection chamber for water coming from the inlet.
  • the water flows out of the collecting chamber in normal operation a line to the rain basin, at the inlet of a throttle or a slide is provided to control the flow to be limited by the line to the maximum allowed.
  • the collection chamber has an overflow threshold. Water running over the threshold can then can be derived via a line.
  • the problem of finite rain pool volume is at a standstill the technology solved by using the rain basin as a rain overflow basin be designed, during heavy rainfall Collected water runs over a threshold and drains away becomes.
  • a receiving water i.e. the natural one intended to discharge the waste water
  • Waters to feed the excess can in a rainwater overflow basin rainwater no longer comprehensible due to a so-called Retention floor filters.
  • This retention floor filter becomes water from the overflow of the rain overflow basin or fed from the overflow of the separating structure.
  • a typical retention filter is in the form of a below e.g. with a suitable seal sealed floor recess educated.
  • the normally dry retention soil filter Water which gradually through the acting as a filter Soil seeps into the drainage system.
  • the planting of the retention soil filter not only helps to reduce Pollutants, but also loosens the soil. This prevents that the filter through fine-grained suspended matter, etc., the can cause gradual inflation, become clogged.
  • the filter effect is generally sufficient for an introduction of the filtered water in the receiving water.
  • the retention soil filter only relieves pressure in extreme precipitation directly at most a few times a year in the receiving water.
  • the object of the present invention is to create something new to provide for commercial use.
  • a basic idea of the present invention is therefore to arrange the individual hydraulic structures relative to each other in such a way that over the overflow water is channelless and pipeless can immediately fall to where its immediate follow-up is guaranteed. It was recognized that this was due to structurally less complex and sometimes even simplifying the construction Changes to the hydraulic structures and their corresponding ones spatial arrangement in a cost-effective manner to save space and is possible while simplifying operations.
  • the basic idea of the invention is first embodied by in a rainwater relief system with a rain overflow basin and a retention soil filter in the overflow area a weir threshold is provided, which is directly in the retention floor filter leads. So the overflowing water will not in a pipe behind the rain overflow basin composed, i.e. e.g. channeled and over longer distances Filter fed, but gets directly into this. This saves both the construction of a long retention floor filter supply line and manifold assembly as well as floor space.
  • the retention floor filter not as preferred as a bottom recess with below of the ground level, but as approximately formed with an earth wall, can in the inventive installation of overflow basin and retention soil filter the walls of the overflow basin in the immediate vicinity in the inflow area also as a limitation of the retention floor filter serve what lowers construction costs.
  • the flow rate of the water flowing into the retention soil filter significantly reduced without known arrangements that the water has to be trickled. This is especially true if the weir threshold width over which the retention floor filter is loaded, more than 5% and in particular approximately 25% of the size of the rainwater overflow basin. It is possible to use the rain overflow basin as a rain cyclone basin to build, in a preferred embodiment the rain cyclone basin generally charged tangentially in the first quadrant and is relieved in the fourth quadrant.

  • the arrangement of the one that loads the retention floor filter Overcurrent weirs in the second quadrant allow training of the overflow area as a circulation trough in which the water masses can be divided into two flow paths. This relaxes the inlet conditions in the retention floor filter continue; the risk that through in the retention floor filter masses of water poured in or uprooted the planting is significantly reduced.
  • the overflow area is trough-shaped, that is preferred Storage area of the overflow basin by a first relief weir relieved into the trough and a lower one at the trough Overflow weir to the retention floor filter provided.
  • the Water therefore flows out of the over two weir thresholds Storage area of the rain overflow basin in the retention soil filter; the second weir threshold in the flow path represents the overflow weir threshold of the Overflow area.
  • a sieve arrangement can be provided in front of the retention floor filter become. With trough-shaped formation of the overflow area with two weir thresholds from the storage area to the retention floor filter can in particular in a manner known per se the relief barrier of the storage area is provided be.
  • the first with a trough-shaped overflow area and the second weir threshold in the direction along the trough channel from each other are spaced. This prevents gushing Spill over the memory area over the first at the same time and second weir threshold directly into the retention floor filter with potentially adverse effects on planting. Rather, the water is first braked and runs slowly and evenly to the overflow weir threshold and in the retention floor filter. If the first and second weir threshold spaced from each other in the direction along the trough are, the trough bottom preferably has a slope from the first to the second weir threshold.
  • a third self-defense is provided in the overflow area, about which extremely large, also from the retention floor filter quantities of water that can no longer be taken in are fed to a receiving water become;
  • a retention soil filter is designed so that this is rare and at most with few rain events is required annually.
  • very heavy rain events is the water freight after the plant is full but mostly already so little polluted and the receiving water so strong flows through that this does not significantly affect water quality impaired.
  • the self-defense is dimensioned that it is when the retention bottom filter accumulation target is reached overflowed without further measures. It's easy for that an appropriate self-defense level is required.

  • a storage device in particular with accumulation boards, which are formed when the overflow area is formed Trough shape can be placed transversely in the trough channel.
  • the stowing device is prevented from Water flows into the retention floor filter, for example when the retention floor filter must be maintained. In such a case the inflow water quantity is simply direct via an emergency drain directed into the receiving water.

  • the actual Retention bottom filter can, as is generally preferred, as Be deepened so that its storage target on or is slightly below the normal floor level.
  • the retention floor filter can drain as needed be pumped dry via the drainage system, in particular using a solar-powered feed pump. This can be used since the retention soil filter after a precipitation does not have to be dried out instantaneously, but the draining completely sufficient within a few days; out of this Weak feed pumps can be reasonably reduced with accordingly Power requirements are used.
  • the drainage of the drainage system is in the rainwater relief system preferably controllable. So through drainage or throttling at the beginning of precipitation even with low Evenly deposit the retention soil filter with water covered and the infiltration is not exclusively concentrated on the inlet area near the weir threshold. A uneven loading of the filter with a corresponding uneven sediment piling is avoided by at least the entire pore space of the filter is jammed, i.e. completely moistened or covered the floor surface becomes. It is preferred to hold it until the water in the Retention space has reached a height of a few centimeters. This will also help the growth of unwanted plants prevented that are entered in the filter and typical are not water loving.
