Definitions

  • the invention relates to a shaft insert for a road inlet shaft, which serves for the filtration of the water flowing into the shaft.
  • Street entrances serve to feed surface water into an underground sewage system and are known as such.
  • the invention has for its object to provide a matched in its design to a known as "Hamburger Trumme” street inlet shaft filter for filtering / cleaning the guided through the shaft inlet surface water.
  • Such a "Hamburger Trumme” characterize the following features: In its lower part, this has a so-called wet sludge trap, in which leaves and other coarse dirt flushed into the Trumme can collect and from which these are regularly removed.
  • the manhole outlet through which the flushed-in water can drain from the drain into the connected sewage system, lies above this wet sludge trap, which makes it possible to practice Filter cartridges can not or insufficiently for a sufficient “fine filtering" can serve.
  • such fine filtering can be desirable then provided in such Trumme, if not only coarse dirt, such as leaves and trash to be retained, but also other, the water contaminating fine dirt particles, such as rubber abrasion of vehicle tires, heavy metals, oil or fuels.
  • the invention proposes designing a manhole insert in such a way that on the one hand its filter unit enabling the retention of fine dirt particles is arranged below its clean water outlet and on the other hand it allows the use of the wet mud trap as a "coarse dirt pickup".
  • a proposed shaft insert also has a so-called support tube, through the upper end of which the dirty water entering the shaft and referred to as raw water can flow in.
  • the raw water is proposed to pass over a guide element at the clean water outlet of the shaft insert to the filter unit.
  • this filter unit can have in its annular filter space a hollow cylindrical filter insert with an inner hollow chamber which can be flowed through radially.
  • the raw water flows in the shaft due to gravity down and can rise within it, wherein it flows through the filter insert radially from outside to inside and penetrates into its inner hollow chamber.
  • the filtered pure water passes from there to the pure water outlet of the shaft insert via which it is guided to the outlet of the shaft.
  • the support tube can form a circumferentially extending from its wall inwardly encircling collar on which the filter unit can rest.
  • the filter unit in turn can for this purpose at its upper end form a radially outwardly extending, annular collar, so that the collar the collar 'overlapping' can rest on this.
  • This covenant can be advantageously designed such that it can safely carry a filter unit weighted by water and the dirt particles collected during filtration, but also reliably holds an exchange filter unit let into the shaft insert from above, even if this is done comparatively high altitude in the shaft insert drops.
  • the filter unit - as previously described - simply by gravity resting on the collar of the support tube.
  • the filter unit engages in a kind of 'snap' and is secured by this against unintentional pushing up or tilting in the shaft insert.
  • a seal - be provided in inexpensive design with a commercial sealing ring - which can effectively prevent the ingress of raw water through this support point.
  • the guide element is arranged in the support tube of the shaft insert and can circumferentially ab emphasizend sealingly with respect to the interior, so as to ensure that the incoming raw water does not get unfiltered into the lying below the guide element support tube areas and / or the pure water outlet.
  • the guide element In its functional position, the guide element can be held by way of example in such a way that it rests on supports which stand up on an inner collar of the support tube or on the upper side of the filter unit arranged below the guide element.
  • the guide element can be designed particularly advantageously as a so-called deflecting cone, which is arranged with its tapered end in the direction of the raw water inlet - ie pointing upwards.
  • the raw water can thus advantageously impinge on the oblique lateral surface of the cone or truncated cone and is derived from this surface beyond the radius of the cone.
  • the Abweiskegel can particularly advantageous at his him down limiting body edge a plugged or molded circumferential sealing lip made of rubber o. ⁇ ., Which liquid-tight upon insertion of the cone in the support tube finally applies to this and the contact point thus reliably seals.
  • a handle - advantageously in the form of an eye bolt or ring nut, a hook or handle - with which, without the use of To require tools, manually removed from the shaft and later re-usable. But it can also be provided to remove the guide element on this handle by means of a hook or the like from the shaft.
  • the support tube may have at or near its upper front end a collar with which it can be supported in the shaft.
  • a collar can be designed, for example, as a circumferential, upwardly widening conical section which, after being suspended in the shaft, is seated, for example, on an inwardly pointing shaft projection.
  • Such a pipe collar allows a centered fit of the manhole filter in the shaft at the same time simple and inexpensive production.
  • it may also be provided for the shaft filter to be supported in the lower part of the shaft, for example by the lower end of the support tube or the filter unit, or otherwise held in the shaft.
  • a proposed shaft insert has a length-adjustable adjustable between the collar and the pure water outlet support tube by means of which the shaft insert to different heights of the support of the collar and the shaft outlet, at the height of the pure water outlet of the shaft insert is arranged to adjust.
  • the support tube may for example be designed telescopically displaceable or have two superimposed pipe sections, which are screwed together via a pipe thread. When turning the lower section thus changes the length of the multi-part support tube and the pure water outlet can be unscrewed to the height of the Schachtausements.
  • this adjustment is possible via support rods in the form of flat material, which are fixed at one end fixed to the upper, the collar-bearing pipe section and projecting on the wall of the support tube down.
  • These support rods have - distributed over the length of each flat bar - openings on, through which a screw with the lower pipe section can be realized.
  • These openings can be provided in the form of slots or individual holes and thus allow a continuous or stepwise adjustment. It can be provided to close an optionally resulting by the adjustment of the support tube length open area by means of an additional cylindrical pipe section.
  • the support tube can have at least one, advantageously also several, passage opening through the pipe wall.
  • the passage openings can advantageously be made large, so that flooded with the water coarse dirt, such as leaves, proceed unhindered and can be continued.
  • the shaft filter may have a pure water space, which is advantageously arranged below the passage opening and above the filter unit.
  • the water designated after passing through the filter can be collected as pure water and fed from there to the pure water outlet.
  • the space of the filter unit, in which the filter material is arranged, is referred to as filter space.
  • This filter chamber has at least one inlet opening for the raw water and at least one drain opening for the filtered pure water.
  • the inlet opening - or at least one of these inlet openings - is arranged below the pure water space. The penetrating into the filter room raw water can thus with increasing Water levels are effectively routed from here to the overlying pure water space.
  • the shaft insert can be connected in a fluid-conducting manner to the shaft outlet at its clean water outlet.
  • a connecting pipe piece which - flexibly shaped or permanently adapted in its design to the shape of the shaft - opens from the pure water outlet in the shaft outlet.
  • the connecting pipe piece for example, bears sealingly against the inner wall of the manhole outlet or a further pipe section attached circumferentially on the outer wall mounted sealing lips.
  • a shaft filter according to the proposal can advantageously have a relief opening - in an advantageous embodiment as a window-like opening of the support tube in the area in which it forms a pure water space.
  • the discharge opening is in this case positioned such that when a predetermined water level is exceeded, the raw water can pass into the pure water outlet and thus into the shaft outlet, bypassing the filter unit.
  • a shielding upwards shielding for example in the form of a over the wall of the support tube outside in the shaft extending, canopy-like piece of sheet metal.
  • a deflector can also be formed by the guide element, said guide element covers the discharge opening by its arrangement.
  • the discharge opening is formed as the open-top end of a hollow truncated cone, which is below the guide element - for example, designed as a deflector cone - is arranged.
  • the upper Abweiskegel and the lower cone each with their tapered region facing up one above the other, the upper Abweiskegel covers the lower - at least such that the discharge opening at the lower cone is shielded against the incoming from above raw water. Trained as Abweiskegel guide in this case forms the Ableitblech for the described shielding of the discharge opening.
  • the deflector cone and the cones arranged therebelow a gap is formed, through which the raw water rising rapidly in the shaft can enter and reach the discharge opening. From there it then reaches the pure water outlet.
  • the raw water level can increase so much in a particularly high arrangement of the discharge opening, that through the thus increasing water pressure in the shaft, the flow through the filter is supported by the raw water advantageous.
  • the filter unit can have a handle, with which it can be used without the use of To require tools to remove the manhole filter.
  • a handle for example, in the form of an attached at its top eye bolt or ring nut, a hook or handle.
  • This handle offers the advantages already described in the application examples of the handle of the guide element.
  • the filter unit can be removed as easy and time saving the manhole insert, cleaned or replaced and then returned to the site back.
  • a road inlet equipped with a proposed shaft insert can effectively combine the advantages of coarse dirt segregation in the wet mud trap with those of a fine filtration realized by the manhole insert.
