Definitions

  • the invention relates to an emergency water weir which has a number of flexible hoses which can be filled with a fluid.
  • Emergency water weirs of this type are known and they have the purpose, for example, of providing banks, quays or dikes with a temporary increase in order to prevent flooding in the event of extremely high water levels in the river or collecting basin there. In most cases, the necessary increase is 1 to 2 meters.
  • An exposed emergency water weir is known, consisting of a number of loose hoses that can be filled with water or air. The hoses are held together by a covering, a net or by belts. It is possible to remove this emergency water weir after use and after emptying.
  • Another known emergency water weir is permanently available at its point of use and consists of a number of flexible hoses which are accommodated in a hollow in the underground in the non-filled state and which in this state are covered by a cover.
  • the lid must be removed before filling the hoses.
  • the hoses are filled with air and are surrounded by a dense covering of flexible material that holds the hoses together.
  • the tubes are superimposed on one another in the inflated state, and the tubes and wrapping are held in an erect state with the aid of supports which must be installed at regular intervals.
  • An emergency water weir is known from US Pat. No. 4,981,393, which consists of a number of flexible hoses which can be filled with a fluid, the hoses lying in the state filled with fluid in a number of layers one above the other and at least two hoses along a longitudinal one Side are connected.
  • This emergency water weir can be set up and removed and consists of a number of units, each of which is constructed from two parallel hoses which are connected to one another along a longitudinal side by a strip of material which is wider than the diameter of the hose.
  • the units are made of PVC and must be stacked to provide an emergency water weir of the desired height.
  • a disadvantage of this known emergency water weir is that it must have a large width in terms of its height if it is to be stable enough to withstand the water forces of the water to be weired, which can be high due to current and / or wind, without toppling over. Furthermore, this emergency water weir cannot be set up quickly because the individual units must be positioned exactly opposite one another. There is also a risk that water will pass through because the connections between the hoses are all approximately horizontal.
  • hoses are stacked offset from each other, a very stable stack of hoses is created, and because of the connections between the hoses in the vertical direction, which are each attached by skipping a hose, it is possible for a certain width of an emergency water weir with a relatively large size To provide height that forms a whole and is to be attached as a unit.
  • the emergency water weir is permanently available at its point of use, and the hoses of the lowest layer are preferably attached directly to the underground on their underside.
  • the hoses are also preferably connected to the substrate along the hoses of the lowest layer from the bottom layer down to a bottom layer. This creates a stable emergency water weir with low material consumption.
  • the hoses are preferably covered in the unfilled state by a cover which preferably contains a steel plate which forms a continuous whole over the length of the hoses, so that the hoses are protected against the weather.
  • a cover which preferably contains a steel plate which forms a continuous whole over the length of the hoses, so that the hoses are protected against the weather.
  • the steel cap When filling the hoses, the steel cap will progressively be lifted due to its inherent deformability from the point where the filling begins. This location may be at the end of the tubing or at a convenient location or locations along the length thereof.
  • the lid can be made from shorter pieces of steel plate exist, which are hinged together.
  • the hoses are preferably also connected to the cover.
  • the cover can form a structural part of the emergency water weir.
  • connections present are preferably shorter than they should be in the case of hoses filled with a circular cylinder in order to obtain a certain flattening of the hoses in the filled state.
  • the connections are tightened, while the hoses lie against one another via a certain contact level. This creates a particularly stable emergency water weir.
  • the hoses are connected to one another in the fluid-filled state in a substantially diagonal direction, which preferably runs away from the water to be weired.
  • a substantially diagonal direction which preferably runs away from the water to be weired.
  • This embodiment can also be permanently present at its point of use and is then preferably attached to the substrate in a substantially diagonal direction.
  • a cover can also be attached, to which the top hoses are attached.
  • the hoses When filled, the hoses are preferably stacked in a substantially pyramid-shaped manner, the uppermost layer of hoses containing one and preferably at least two hoses, so that this is possible with as little Hoses such a high possible, stable emergency water weir is obtained.
  • the uppermost tube With an uppermost tube, a cross section as slim as possible is obtained; two or more hoses provide better support for a lid.
  • the hoses in the non-filled state are accommodated in a depression in the subsurface which is essentially the same width as the width of the lowermost layer of hoses in the filled state, so that the emergency water weir as little as possible the exterior of the dike or the quay disturbed and accessible with a cover at this point remains during the time in which the emergency water weir is not needed.
  • the lowest hose layer then preferably contains one hose less than that except for a lowermost layer.
  • the hoses are made from one or more webs of textile material, such that the connections between the hoses are formed by strips which protrude from the hoses.
  • the textile material made of plastic fibers gives the hoses a high strength, and with the help of the excellent strips, the hoses can be easily attached to one another, for example by sewing or clamping.
  • the strips on the hoses are produced by the webs of textile material being provided with preferably waterproof clothing made of a suitable plastic material such as polyurethane or PVC, and by the webs being glued to one another or thermally welded along their edges.
  • the hoses are made in this way in a simple manner, and the hoses are just as simple and fast to fasten to each other by gluing the strips together on the tubes or thermally welded.
  • the textile material has been woven or knitted into a round tube, which is provided on the outside with preferably waterproof clothing made of a suitable plastic material such as polyurethane or PVC, where individual strips of textile material provided with the same clothing are glued or thermally welded are.
  • a suitable plastic material such as polyurethane or PVC
  • the strips on the hoses are produced by the textile material being woven or knitted as a whole at the edges, the textile material preferably being waterproof using an essentially waterproof fabric or clothing, for example made of rubber or plastic . Because the strips on the hoses are also made from the material from which the hoses themselves are made, a strong connection is made between each strip and its hose, while the hose itself is also made as a whole, so that the risk of Opening is small.
  • the hoses are to be fastened together again by sewing or clamping the strips or, if suitable clothing is used, by gluing or thermally welding the strips.
  • connection between the hoses is water-resistant and, in the presence of a connection between the hoses and the base and / or the cover, this connection is also preferably water-resistant, so that the water resistance does not depend on the sealing effect of the contact between the hoses and each other Contact between the hoses and the surface is dependent. If the hoses are connected to each other in the vertical direction with waterproof material when filled, the emergency water weir is thereby sealed over its entire height with additional security.
  • the diameter of the hoses is preferably 300 to 2000 mm, since for most applications there is then a favorable relationship between the amount of material required for the hoses and the required thickness of this material.
  • the hoses are provided with inspection hatches, which can be sealed watertight before and as required, so that the hoses, if they have a sufficiently large diameter, can be inspected from the inside.
  • a shield is fitted on both sides of the hoses between the cover and the base in order to protect the hoses against vandalism, whereby the shield preferably contains a plastic fabric, preferably reinforced with steel or another material with a high tear resistance.
  • hoses are connected to the substrate and / or to a cover, it is advantageous if the hoses are provided on their side to be connected with a bead which can be clamped to the substrate and / or the cover in clamping means. This enables simple and quick, reliable fastening of these hoses when installing an emergency water weir that is permanently available at its point of use.
  • Figure 1A shows a first preferred embodiment of a flexible tube.
  • Figure 1B shows a second preferred embodiment of a flexible tube.
  • FIG. 2 schematically shows an emergency water weir permanently present at its point of use in cross-section.
  • FIG. 3 schematically shows another embodiment of an emergency water weir that is permanently present at its point of use in cross-section.
  • FIG. 4 shows an emergency water weir permanently in front of a quay at its point of use.
  • the hoses of the emergency water weir according to the invention are preferably made of textile material formed with plastic fibers.
  • the hoses are made in such a way that each hose normally has an excellent strip on two opposite sides.
  • Such a hose 50 is shown in FIG. 1A.
  • the tubes with strips can be used in different ways getting produced.
  • a simple and quick way consists of the use of two webs of textile material, which are covered on at least one side with a suitable material, and which are glued together at their edges or thermally welded to one another, so that the connected edges form two strips 52, 53 (see FIG. 1A) and the remaining webs of the actual hose 51.
  • Such hoses can be sewn or clamped together with their strips, or if the strips are provided with suitable clothing on at least one side, glued or welded to one another.
  • Another production method consists of weaving or knitting a tube, on which two strips are directly woven or knitted during the manufacture of the tube.
  • a tube 51 with strips 52 and 53 is formed directly, as shown in FIG. 1A.
  • the tubes can be connected to one another in the manner described above.
  • the textile material is woven or knitted into a round tube, as indicated at 56 in FIG. 1B.
  • the tube 56 can then be clad with a suitable material, after which the strips for the webs, which are also clad with a suitable material, can be glued or welded on.
  • a suitable material Preferably, three webs joined together at one edge are used as strips 57, 58, see FIG. 1B, two webs being glued or welded to the tube and the third web forming the outstanding strip.
  • hoses with more than two strips can also be produced by fastening more than two strips along the edges, forming more than two strips or attaching more than two strips to a rounded tube.
  • Certain tubes which only need to have a strip, can also be made from just one sheet of textile material, which is double-folded over its length and sewn, glued or welded to one another at the edges. Also, only one stripe can be woven or knitted.
  • FIG. 2 shows an emergency water weir 11, which is permanently available at its point of use.
  • the emergency water weir 11 consists of a recess which is designed as a case 12 in a dike 10, in which hoses 15 to 26 are received in the unfilled state of the emergency water weir and which is closed by a cover 13 in the unfilled state.
  • Use was made of the hose type of FIG. 1 for the hoses 15 to 26.
  • the bottom hose layer 15, 16, 17 is connected at its underside directly to the bottom of the case 12, in that the strips on the underside of the hoses are provided with a beaded rim which is held on the bottom of the case by clamping means.
  • hoses 25 and 26 are attached directly to the cover 13.
  • the hoses 18, 19, 20, 21 are connected to the bottom of the case 12, in that the strips on these hoses are lengthened with fabric lengths 30, 31, 32, 33, which are provided with a beaded edge at their end, which are attached to the bottom of the case by clamping means.
  • the hoses 18, 21, 22, 23 and 24 are fastened to the cover 13 with the aid of fabric lengths 42, 43, 39, 40, 41.
  • the tubes 15 and 22 are connected by a web of fabric 34, the tubes 16 and 23 by a panel of fabric 35 and the tubes 17 and 24 by a panel of fabric 36.
  • the fabric sheets are attached to the respective strips of the hoses in question.
  • the tubes 19 and 25 and the tubes 20 and 26 are connected by fabric webs 37 and 38.
  • connection between the hoses to each other and the connections between the hoses and the lid and those between the hoses and the case are vertical, creates a safe, water-resistant effect of the emergency water weir 11.
  • the hoses and the connections between them should be in the manner be made as described for hoses 50 or 55 of Figure 1A or 1B. It is not necessary, but desirable, that the vertical connections 31 to 41 are watertight.
  • FIG. 2 is a schematic representation of the emergency water weir 11, the hoses being reproduced in a circular cylindrical manner on average.
  • the hoses will not be filled under such a high pressure that they are circular cylindrical on average.
  • the connections 30 to 41 are then also shorter than shown in FIG. 2.
  • the upper edges of the case 12 will be rounded, so that the tubes 18 and 21 are stronger Dimensions will have a circular cylindrical diameter.
  • the emergency water weir 11 has two shields 14 on both sides, which consist of a plastic fabric, possibly reinforced with steel wires or wires made of another material with a high strength such as carbon fiber or aramid fiber. When the emergency water weir is not in use, these shields are also accommodated in the case 12.
  • the hoses have a diameter of approximately 1000 mm.
  • the emergency water weir 11 is therefore suitable for weir water at water levels up to about 2 m above the dike 10.
  • the top layer preferably consists of at least two tubes.
  • the cover 13 is provided for continuous use of the top of the dike in the unused state of the emergency water weir 11, for example for traffic and transport purposes.
  • the hoses can have a length of 500 to 1000 m, and the cover 13 can have the same length as a steel plate.
  • the hoses can also have a shorter length.
  • the hoses will filled with water at one end by a pump and are progressively inflated from this side. Due to the inherent elastic deformability of the steel plate, the cover 13 is then also pushed upwards in a progressive manner.
  • the cover 13 can, however, also consist of shorter pieces of steel plate which are connected to one another by hinges.
  • FIG. 3 shows an emergency water weir 60, which largely corresponds to the emergency water weir 11 of Figure 2; the same parts are then given the same reference numbers. Only the vertical connections 30 to 41 from FIG. 2 have been replaced by the essentially diagonal connections 61 to 74. As a result, the hoses can be connected directly with their strips, so that less material is required. Through these essentially diagonal connections, the hoses are pressed into their nested position by the pressure of the water to be weired.
  • FIG. 4 shows an emergency water weir 101, which is similar to the emergency water weir of FIG. 2, but which has the purpose of being installed in a quay 100 and must therefore be as narrow as possible.
  • the uppermost tube layer has only one tube 111.
  • Emergency water weir 101 has a case 102 which is relatively deep and is completely filled by two hoses 105, 106 in a state filled with fluid. On top there are three hoses 106, 107 and 108 in the filled state, thereon two hoses 109 and 110 and finally the uppermost hose 111. The top 103 rests on the top hose 111. The lowest hoses 105, 106 are at the bottom of the Koffers connected at 120, 121. Furthermore, the hoses have excellent strips of material 122 to 129, as described in Figure 1, for mutual connection and for connection with cover 103 and case 102, just like the emergency water weir from FIG. 2.
  • This emergency water weir 101 also has two shields 104 on both sides, and also a number of cables or pull straps 130, 131, 132, 133 are attached so that the Hoses 106 and 107 are received within the case when idling or pumping empty.
  • the emergency water weir 11, 60 or 101 When using the emergency water weir 11, 60 or 101, it must be ensured that the resultant of the horizontal force of the water to be weired and the vertical force of the weight of the emergency water weir itself runs through the central part of the base of the emergency water weir.
  • the weight of the (concrete) case 12 also plays a role. If the resulting force does not run through this central part, the emergency water weir can tip over with a suitcase and everything under the influence of the pressure of the water to be weired from the dike or quay.
  • the pressure in different hoses can be given a different value in order to increase the stability.
  • the hoses are filled with water in their effective state, and possibly partly with a solid, granular substance such as sand.
  • the cover can be lifted locally, if necessary, so that they hang on the cover and the hoses are provided with inspection hatches to check the hoses for leaks from the inside.
  • the hoses can also be filled with air for inspection. This makes it possible to fill the hoses one by one or with some in a vertical row coupled with strips at the same time and to inspect them from the side, for example for watertightness.
  • the tubes can also consist of extruded tubes made of fiber-reinforced plastic material.
  • the invention thus provides an emergency water weir which can either be temporarily attached to the desired location or is permanently present at its point of use and which provides a dimensionally stable water weir using as little material as possible. Little work is required to bring the water weir into an effective state.
  • the emergency water weir is not only suitable as an emergency water weir for dikes or quays, but also as an emergency water weir for houses or factories in a flood bed, for example, or as a weir for contaminated liquids such as fire fighting water on factory premises. Even light traffic is possible via the raised lid.
