Definitions

  • the present invention relates to a retention system for precipitation water and wastewater according to the preamble of claim 1.
  • Corresponding restraint systems serve to ensure a buffer effect in a sewer during a sudden attack of increased water masses, in particular due to heavy rainfall events.
  • a pressure relief valve in the conventional sense of the art.
  • this is a storage space channel between an inlet and a spout used by accumulated in an increased accumulation of water mass transported from the sewer mixed water (rainwater and wastewater) and, when exceeding a certain level in an overflow shaft, with a discharge channel in Connection stands, escapes.
  • coarse matter e.g. Suspending agents and contaminants are retained in the sewer system.
  • retention devices are provided in the area of the overflow shaft.
  • the DE 20 2007 004 927 U1 describes a retention system for rainwater and wastewater according to the preamble of claim 1.
  • This known restraint system comprises a perforated tube, which starts from the inlet an overflow shaft and ends in the region of the transition of the overflow shaft into the reservoir channel. Between the overflow shaft and the storage space, an opening is provided which can be closed by a designed as a floating barrier partition. When the baffle wall is raised while floating on the surface larger dirt particles are held, but suspended below the raised baffle can get into the overflow shaft.
  • the DE 2010 05 479 U1 describes a restraint system with a straight-line overflow threshold which simultaneously includes a retention grid.
  • the retention system is designed for connection to a storage space channel.
  • the DE 199 111 248 C1 describes a storage channel for damming particular rainwater in drainage networks of mixing systems.
  • the storage space includes a source pot, at the top of a grid ring is provided.
  • the DE 37 14 947 A1 shows a retention system for mixed water from waste water and rainwater, in which a double threshold for two-way overflow or a ring threshold for round overflow of the mixed water is provided in the overflow shaft.
  • the DE 199 16 964 A1 discloses a retention system for rainwater and wastewater, through which runs from the inlet to the outlet of the storage space channel a mixed water channel of compared to the storage space channel reduced diameter, which perforations of predetermined size to pass through of water, with coarse materials, such as suspended solids and / or contaminants, however, to be retained.
  • the precipitation water and waste water which contain suspended matter and / or contaminants, flows from the inlet through the mixed water channel to the outlet of the reservoir channel. When an increased seepage of water mass occurs, the amount of water in the mixed water channel swells and flows through the perforations into the reservoir channel.
  • the object of the present invention is to provide a restraint system of the generic type with improved performance.
  • the entire storage space channel is available as a storage volume for the precipitation water and wastewater and thus the retention or separation function of the retaining element only begins when the Stowage channel is filled in its capacity as mixed water storage to a certain extent. Due to its elongated shape, the retention element provides an overall increased retention performance compared to a retention rake that is usually positioned directly in the overflow shaft. Due to the design, there may be no rupture in the restraint system according to the invention, since the rainwater and wastewater from the inlet directly into the large volume storage space channel and from there into the outlet and the passage is not limited by an additional channel.
  • At least one retaining channel provided with passages is provided in the overflow shaft as a retaining element extending from the latter along the reservoir channel in the direction of the outlet.
  • the accumulating from the reservoir channel rainwater and sewage fills with appropriate attack the reservoir channel and flows as soon as the water level reaches the retention channel in this radially. From the retention channel, the water then flows into the overflow shaft.
  • the retaining channel extends only over a partial length of the storage space channel in the direction of the outlet. Since the retaining element or the retention channel does not have to extend through the entire storage space channel as in the prior art mentioned at the beginning, but extends only over a partial area in this, it is possible to retrofit existing retention systems in a simple manner.
  • the passages on the retaining element are suitably selected by their arrangement, dimensioning, shaping or a combination thereof such that suspended matter such as e.g. dissolved or undissolved cellulose components, tissue components and dirt of any kind are retained so that the latter or the latter does not get into the overflow shaft.
  • the retention channel is located substantially in the middle region of the storage space channel.
  • the retention effect within the storage space channel can be "duplicated" in a simple manner.
  • the respective retaining channel by means of fastening elements, such. by means of pipe clamps or by means of a support frame, positioned in the storage space channel.
  • the fastening elements are preferably made of metal or plastic.
  • such a retaining channel has a tapered bottom and top.
  • the passages of the retaining channel are slit-shaped or perforated.
  • the retaining channel or the wall region to form a retaining channel have a grid-like structure.
  • Reference numeral 22 in Fig. 1 shows an expedient embodiment of a retention system according to the invention for rainwater and wastewater in their entirety.
  • the retention system 22 comprises a large volume storage space channel 5 located between an inlet 1 and outlet 2, which serves as a buffer for mixed water (precipitation water and waste water) at an elevated level Accumulation of water is used.
  • the inlet 1 in the storage space channel 5 is connected to a z. B. through the lower portion of a overflow shaft 3 guided pipe with a (not shown) sewer network in connection.
  • the overflow shaft 3 has an overflow 24, which leads to the outside in a discharge channel 4.
  • the entire retention system 22 is located in the ground. Via access shafts 18, 19, 20 and 21, an access in the area of the overflow shaft 3, two accesses in the region of the storage space channel 5 and an access in the area of the throttle shaft 23 are provided.
  • the retention channel 6 or 8 in Fig. 1 It leads to a in the overflow shaft 3 and extends from there, starting in the direction of the outlet 2 over a partial length of the storage space channel 5.
  • the outlet 2 facing the end of the retaining channel 6, 8 is located a respective respective end plate 16, 17.
  • the respective retaining channel 6, 8 is provided with a plurality of passages 7 in order to ensure a water passage from the storage space channel 5 into the respective retention channel 6, 8.
  • wastewater flows from a (not shown) sewer system via the inlet 1 in the storage space channel 5 and from this via the outlet 2 again in the (not shown) sewer system back.
  • wastewater flows from a (not shown) sewer system via the inlet 1 in the storage space channel 5 and from this via the outlet 2 again in the (not shown) sewer system back.
  • a sudden increase in the amount of water due to a cloudburst or the like Flows a multiple of rainwater together with the sewage system located in the sewer system into the storage space channel 5 and accumulates due to the small-sized spout 2 within the storage space channel 5 quickly.
  • the two retention channels 6, 8 are fully positioned within the storage space channel 5.
  • Fig. 3 The positioning is done as out Fig. 3 can be seen via fasteners, such as over pipe clamps 9, 10, with which the respective retaining channel 6, 8 is fixed to the inner wall 12 of the storage space channel 5 in the upper and lower regions.
  • the passages 7 are formed as slots 13 or perforation.
  • a kind of slot tube can be used for this purpose. The entry of water (see straight line arrows) takes place all around.
  • FIG. 4 An alternative embodiment of the respective retention channel 6, 8 shows Fig. 4 , There is formed via a corresponding wall portion 11, which has respective passages 7 in the form of slots 13, a retaining channel 6 and 8 together with the inner wall 12 of the storage space channel 5.
