Definitions

  • the invention relates to a water barrier with a channel-shaped foundation body with spaced side walls, wherein the foundation body is connected via a bearing with a flap, which due to the buoyancy of the water from a starting position in which the flap extends between the side walls in a Lock position, in which a head-side end extends over the foundation body, is pivotable.
  • the DE 27 57 704 B2 discloses a water barrier with a channel-shaped base body, on which a flap is pivotally mounted transversely to a locking direction on a bearing. A joint between the flap and the foundation body is sealed watertight by means of a sealing strip.
  • the flap has cavities that can be blown out with compressed air to create a buoyancy that causes or assists in erecting the flap.
  • the main body is arranged below the flap, a longitudinally extending hose with a pressure medium space. Water is pumped into the hose to raise the flap.
  • the water present at the upper side of the flap opposite the hose which is to be stopped by the flap pivoted into a blocking position by means of compressed air and the hose filled with water, rises to the level at different levels both sides of the flap.
  • a body covering the top side starting position the water is drained from the hose.
  • a flood-retaining device with a channel-shaped foundation body are arranged on the pivotally mounted about a horizontal axis flaps having a float cavity which produces a buoyancy for erecting the flaps in a blocking position, the flaps in a lowered starting position, the gutter of the body cover over the top extend.
  • the flaps are composed of closed-end plastic tubes, which are joined together with the pivot axis of the flap perpendicular and mutually parallel axis in the plane of the flap close together.
  • the adjoining flaps engage each other at their mutually facing, perpendicular to the pivot axis abutting edges with a connection which allows a mutual movement in the plane of the barrier flaps, but substantially no mutual pivoting about the pivot axis.
  • the invention has for its object to provide a water barrier of the type mentioned above, the flap of which relative to the foundation body pivotally halterndes bearing has a robust and relatively watertight structure.
  • Another task is the protection of buildings by automatic flood barriers, as they are used at building entrances, driveways of underground garages, waterfront promenades, etc.
  • the creation of inner-city, temporary storage space on streets and squares to avoid emergencies is also desirable.
  • the protective elements should float on their own and make it unnecessary to have a power supply interrupted in the event of a flood. They should also be functional regardless of the workload of the emergency services. In addition, a non-slip profiling of the surface, snow, the protection against contamination, the easy flushing of the system after the occurrence of floods and the like in the invention is possible.
  • the object is achieved in that the bearing is formed as a extending between the side walls web with a rounded web head, wherein the web head is mounted in a groove having a radius of the flap.
  • the web of the bearing extends over the entire length of the foundation body and, like the groove in the flap on a relatively smooth surface.
  • the entire foundation body with the web by means of a slip finisher or extruder machined and before Place to be installed.
  • the flap is due to its own weight safely on the bridge and is sealed pivotally mounted on the bridge head.
  • the bridge head and the groove act together in the manner of a saddle joint. Even when the lift of the flap this is dimensioned such that the joint or bearing is maintained, so the groove rests on the web head.
  • the flap can be machined to achieve a required surface finish and has a relatively large width.
  • the arrangement of one or two flaps may be sufficient, which are advantageously sealed, in particular on their free longitudinal sides, in relation to a peripheral building, for example a concrete retaining wall.
  • the bearing is expediently spaced from a foot-side end of the flap such that a two-armed lever is formed whose lever end associated with the foot end is dimensioned shorter than the lever end associated with the head end ,
  • the long lever arm is underflowed by the water and experiences the buoyancy.
  • the long lever arm in consequence represents the effective barrier against the water which builds up between the web of the foundation body and the head end of the flap.
  • the web of the bearing has a groove on the side facing the long lever arm of the flap, into which groove a nose of the flap engages in its initial position. Sonach the flap is effectively held against the web at a load from the direction of the head end.
  • the groove in the flap in the direction of the foot-side end is chamfered, thereby forming an incision in which engages a corresponding projection on the web of the bearing in an end position of the locking position of the flap, the web of its rounded web head in the direction of the projection slanted runs. Accordingly, a kind of end stop for the blocking position of the flap is provided.
  • the watertight concrete joint formed by the web and the correspondingly shaped groove in the flap allows the use of sandwich elements as a flood barrier in practice as well as the introduction of the entire developed system, which essentially comprises the foundation body and the flap coupled thereto, in the precast industry.
  • it lacks the use of sealing means in the hinge region or the region of the bearing between the valve acting as a barrier in its distended locking position flap and the foundation, ie the foundation body, contrary to the previously known systems.
  • the flap is to be mounted in its initial position as free of disturbing transitions and paragraphs on the foundation body has, according to a development of the founding body at the free end of the web adjacent side wall an angled portion whose tip is oriented in the direction of the opposite side wall and the a leg extends parallel to a connecting the two side walls of the foundation body bottom, the slope of the bend rests on a corresponding bevel on the foot-side end of the flap in the initial position on the upper side.
  • the base body at its the head end of the flap associated leg on an upper-side recess, so that the flap is received in the starting position on the top side flush in the foundation body.
  • the founding body In order to guide the flap-raising water into the channel-shaped foundation body below the flap and in particular to divert residual water below the flap in its initial position, for example in a channel, has in design of the founding body at least one water inlet in the region of the side wall having the recess and at least one bottom side Water drain on.
  • the base body, the bridge with the bridge head and the flap are made of concrete.
  • the use of dense high-performance concretes enables cost-effective, filigree and permanently reliable solutions with a very high life expectancy in sandwich construction.
  • the flap has a relatively low weight and thus reliably subject to the buoyant force of inflowing into the foundation body water, the flap has a core of a polystyrene foam.
  • the core may also be made of a polystyrene foam or the like. The person skilled in the art will select a suitable material.
  • adjacent flaps are mutually sealed against each other at their adjacent longitudinal sides.
  • adjacent flaps have on their adjacent longitudinal sides projections and or recesses, which are filled with elastic sealing profiles.
  • the water barrier comprises a channel-shaped foundation body 1, which essentially comprises two side walls 2, 3 which are aligned parallel to one another and spaced apart from one another and one the two side walls 2, 3 connect the base 12.
  • a pivotable flap 4 is arranged between the two side walls 2, 3 of the foundation body 1, which in its starting position runs with its upper side flush with the free end faces of the side walls 2, 3.
  • a recess 6 is formed, on which the head-side end 5 of the flap 4 rests.
  • a bevel 8 is formed on the upper side.
  • the chamfer 8 of the flap 4 is overlapped in the initial position of the flap 4 by a bevel 9 an angled portion 10 at the free end of the associated side wall 3, wherein a tip 11 of the bend 10 is aligned in the direction of the recess 6 having side wall 2.
  • a groove 13 is provided on its bottom side facing the bottom 12 in the starting position, which groove is bevelled in the direction of the foot-side free end 7 of the flap 4 and has an incision 14.
  • the groove 13 has a radius 15.
  • the groove 13 is part of a saddle joint-like bearing 16, the further bearing component is formed by a web 17 which extends between the two side walls 2, 3 of the foundation body 1 outgoing from the bottom 12.
  • the web 17 has a rounded web head 18 with a groove 19 and can be either integral part of the foundation body 1 or it is prefabricated as a separate component with a high surface quality and connected during casting of the foundation body 1 on site with these.
  • the pivotally mounted on the web 17 flap 4 forms a two-armed lever whose the foot-side end 7 associated lever arm is dimensioned substantially shorter than the head end 5 associated lever arm.
  • the foundation body 1, the web 17 and the flap 4 are made of concrete.
  • the flap 4 has a relatively low stability with a relatively high stability
  • the flap 4 is provided with a core 20 made of a polystyrene foam or polystyrene foam.
  • the foundation body 1 In the foundation body 1 are located in the head end 5 of the flap 4 facing side wall 2 water inlet 21 and in the bottom 12 water drains 22, which may be coupled to a sewer network.
  • the flap 4 is according to Fig. 1 aligned with its top substantially flush with the top of the foundation body 1 extending.
  • the head end 5 of the flap lies in the recess 6 of the associated side wall 2 and the foot end 7 of the flap 4 is located with its chamfer 8 below the slope 9 of the bend 10 of the adjacent side wall 3 of the foundation body 1.
