Emergency dam

p0001The invention relates to a Notwasserwehr, which has a number of flexible tubes which can be filled with a fluid.

p0002Such Notwasserwehre are known, and they have the purpose, for example, banks, wharves or dikes to be provided with a temporary increase in order to prevent flooding with extremely high water levels inside the existing flow or collection basin. The necessary increase in most cases, 1 to 2 meters. Thus, an exposed Notwasserwehr is known consisting of a number of loose tubes which can be filled with water or air. The tubes are held together by a wrapper, a net or by belt. It is possible to remove after use and after emptying this Notwasserwehr. Another known Notwasserwehr is continuously present at its site of use and consists of a number of flexible hoses, which are incorporated in non-filled state in a cavity in the ground and which are covered in this state by a cover. Before filling the tubes, the cover must be removed. The hoses are filled with air and are surrounded by a tight envelope of flexible material, which holds the hoses. The tubes are superimposed in the inflated state, and the hoses and cladding are held by means of supports which are attached at regular intervals, in the erect state.

p0003It is a disadvantage of this known Notwasserwehre that an envelope or the like must be mounted to hold the tubing. This means that a lot of material is necessary, whereby the manufacturing costs of Notwasserwehres are high. An additional disadvantage of the known, permanently available on its site of use Notwasserwehres is that it is necessary to establish support and to remove it, which is very labor intensive.

p0004From the American patent specification 4,981,393 a Notwasserwehr is known which consists of a number of flexible tubes which can be filled with a fluid, wherein the tubes in the filled fluid state in a number of layers one above the other and at least two hoses along a longitudinal side are connected together. This Notwasserwehr is tiltable and removable and consists of a number of units that are each made up of two parallel tubes which along one longitudinal side by a strip of material which is wider than the diameter of the hose, are connected to each other. The units are made of PVC and must be stacked to give a Notwasserwehr the desired height.

p0005A disadvantage of this known Notwasserwehres is that it has a large width is must have if it is to be stable enough to the water forces to struggling water, which can be high by flow and / or wind to withstand without tipping over in terms of its height. Furthermore, this is not Notwasserwehr build quickly, because the individual units over must be placed exactly today. There is also the danger that it will pass the water, because the connections between the tubes all running in an approximately horizontal plane.

p0006It is an object of this invention to provide an improved Notwasserwehr.

p0007This object is achieved according to the invention with a Notwasserwehr, wherein in cross-section the axes of the hoses facing each other offset, and the hoses are connected in the filled fluid state in the vertical direction with each other, wherein the connections between the tubes respectively skipping a layer are attached.

p0008Thus, the hoses are stacked opposite to each other offset, created a very stable stack of tubes, and because of the connections between the tubes in the vertical direction, which are respectively skipping of a hose, it is possible with a certain width a Notwasserwehr with a relatively large to gain height, which forms a whole and is to be mounted as a unit.

p0009According to an advantageous embodiment, the Notwasserwehr is permanently available on its site of use, and preferably the tubes of the bottom layer are attached to its underside directly on the ground. Preferably, the hoses are connected from the bottom to a layer from their underside on the tubes of the lowermost layer along with the substrate. This is given with low material consumption a place solid Notwasserwehr.

p0010Preferably, the tubes are covered in non-filled condition by a cover, which preferably comprises a steel plate which forms a continuous whole over the length of the hoses so that the hoses are protected against weathering. The steel cover is by its inherent ductility from the point where filling begins when filling the tubes, can pick up progressively. That body may be located at the end of the hoses or at a convenient location or at low points along the length thereof. However, the cover can be made of shorter steel plate pieces which are hingedly connected to each other.

p0011Preferably, the tubes are also connected to the lid. The lid can form a constructive part of Notwasserwehres.

p0012Preferably, the present compounds are shorter than they should be circular cylindrical with filled tubes in order to obtain a certain flattening of the tubes in the filled state. If the tubes are filled to a sufficient degree, the connections are tightened, while the tubes are above a certain level contact to today. This causes a particularly stable Notwasserwehr.

p0013Alternatively, the hoses are connected in the fluid-filled state in a substantially diagonal direction to each other, which preferably runs away from the struggling to water. This way, no wide connections between the hoses necessary, so that hardly any material is required for the form stability. The diagonal direction of struggling to water ensures that the compounds by the water pressure to come under tension and keep the hoses their stacking.

p0014This embodiment can also be provided at its point of use and is then preferably attached to the substrate in a substantially diagonal direction constantly. Just may be on the cover what the top tubes are attached.

p0015Preferably, the tubes are stacked pyramid were full essentially, the top layer contains a hose, and preferably at least two tubes, so that with as little possible hoses such high potential, stable Notwasserwehr obtained. With a top tube has a so slim possible cross-section is obtained; two or more tubes form a better support of a lid.

p0016According to an advantageous embodiment, the hoses are included in non-filled state in a depression in the ground, the same width is essentially the width of the lowermost tubing layer in the filled state, so that the Notwasserwehr the outside of the dike or the quay as impossible distraught and cover with a lid at this point remains passable during the time in which the Notwasserwehr is not needed.

p0017Preferably then the lowermost tubing layer contains a tube less than the up to a lowermost layer.

p0018According to an advantageous embodiment, the tubes are made from one or more webs of textile material, such that the connections between the tubes are formed by strips which protrude from the hoses. The fabric made of synthetic fibers gives the tubes a high strength, and with the help of outstanding strips are easy to attach hoses for example by sutures or pins each.

p0019According to an advantageous embodiment, the strips are made on the hoses by the webs of textile material are provided with a preferably waterproof clothing from a suitable plastic material such as polyurethane or PVC, and by the webs are glued along their edges to each other or thermally welded. The hoses are manufactured in this manner on a simple way, and the bottles are equally simple and rapid way to fasten to each other by the strips are glued to the tubes with each other are thermally welded to each other or.

p0020According to another advantageous embodiment, the fabric is woven or knitted into a round tube, which is provided on the outside with a preferably waterproof clothing from a suitable plastic material such as polyurethane or PVC, where individual strips glued LABEL FOR fabric having a same clothing or thermally welded are. By the hoses are made as a woven or a knitted, round tube, these hoses will be very strong, so that the risk of rupture is very small. The strips can be adhered to the clothing of the hoses or thermally welded again so that the tubes are mutually connect again in this way by means of the strips.

p0021According to yet another advantageous embodiment, the strips are made on the hoses by the fabric is woven or knitted at the edges to form a whole, and preferably the fabric is waterproof by a substantially waterproof fabric or clothing, is used, for example, rubber or plastic , Characterized in that the strips with the aid of the material from which the tubing is on the hoses themselves, are prepared, a strong connection between each strip and its tube is manufactured while the tube itself is made as a whole is such that the risk of is tearing small. The tubes are again by sutures or pins of the strips, or when a suitable clothing is applied to mutually fix by gluing or thermal welding of the strips.

p0022For added strength steel wires or wires made of another material are preferably taken with a high strength in the textile material.

p0023In advantageous manner, the connection between the hoses is wasserwehrend and the presence of a connection between the hoses and the ground and / or the lid is preferably also this connection wasserwehrend so that the weir ability not and by the sealing effect of the contact between the tubes to each other the Contact between tubes and underground depends. If the hoses are connected in the filled state in the vertical direction with waterproof material with each other, which is hereby Notwasserwehr tightly over its entire height with additional security.

p0024Preferably, the diameter of the tubes is 300 to 2000 mm, as for most applications then there is a favorable relationship between the required amount of material for the tubes and the required strength of this material.

p0025In advantageous manner, the hoses are equipped with inspection hatches that are waterproof sealed before and as needed, so that the hoses if they have a sufficiently large diameter, can be inspected from the inside out.

p0026According to an advantageous embodiment, at constantly present on their point of use hoses, the hoses are covered in non-filled state by a cover to protect both sides of the hoses between the lid and the ground a shield attached to the hoses against vandalism, which the shield is a preferably, contains preferably with steel or other material having a high tear resistance fabric reinforced plastic.

p0027When tubing with the substrate and / or with a lid are connected, it is advantageous if the tubes are provided on their side to be connected with a beaded edge which can be clamped in clamping means on the base and / or lid. This allows easy and fast, reliable fastening of these hoses when installing a permanently available on its site of use Notwasserwehres.

p0028The invention will be explained with reference to two preferred embodiments.

p0029Figure 1A shows a first preferred embodiment of a flexible tube.

p0030Figure 1B shows a second preferred embodiment of a flexible tube.

p0031Figure 2 shows schematically a continuously existing at its point of use in cross Notwasserwehr average.

p0032Figure 3 shows schematically another embodiment of a permanently present at its site of use in cross Notwasserwehr average.

p0033Figure 4 shows a continuously available on its site of use Notwasserwehr before a quay.

p0034Hoses Notwasserwehres according to the invention are preferably made of made with plastic fibers formed fabric. The hoses are manufactured in such a way that each tube normally on two opposite sides has an excellent strip. Such a hose 50 is shown in Figure 1A.

p0035The hoses with stripes can be prepared in various ways. A simple and easy way comprises the use of two webs of textile material, which are covered at least on one side with a suitable material, and which are adhered to one another at their edges or thermally welded to each other, so that the joined edges form two strips 52, 53 (see figure 1A) and the remaining traces of the actual hose 51. Such hoses may stitched together with its stripes or be clamped, or when the strips are provided on at least one side with a suitable clothing, are glued together or welded.

p0036Another method of preparation consists of the weaving or knitting a tube, in the which during manufacture of the pipe directly or mitgewebt mitgestrickt two strips. So immediately produced a tube 51 with integrally formed strips 52 and 53, as shown in Figure 1A. The tube can be connected in the manner described above to each other.

p0037According to a third manufacturing method, the fabric is woven or knitted into a round tube, as indicated in Figure 1B with 56th The tube 56 can then be covered with a suitable material, after which the strips can be for cars, which are also covered with a suitable material, glued or welded. Preferably, three interconnected at one edge webs as strips 57, 58 used, see Figure 1B, in which two webs are glued or welded against the pipe and the third path forms the excellent strips. However, it is also possible to attach the strips such as by sewing to the circular woven or knitted tube around 56th

p0038Although most hoses are used with two strips, the manner described above can correspondingly be produced tubes with more than two strips, by more than two sheets are attached along the edges, more than two strips are concomitantly or more than two stripes on a roughly formed tube are attached.

p0039Certain tubes which need only have a strip, can also be prepared from only a sheet of textile material, which is double-folded along its length and sewn at the edges to each other, is glued or welded. Even just may be mitgewebt or mitgestrickt a strip.

p0040Figure 2 shows a Notwasserwehr 11, which is continuously present at its site of use. The Notwasserwehr 11 consists of a recess which is designed as a boot 12 in a dike 10, are received in which in nichtgefülltem state of Notwasserwehres tubes 15 to 26 and which is closed in non-filled condition by a cover. 13 For the tubes 15 to 26 has been made on the type of hose 1 use. The lowermost tubing layer 15, 16, 17 is connected on its underside directly to the bottom of the trunk 12, characterized in that the strips are provided at the bottom of the tubes with a rim which is held by clamping means on the bottom of the suitcase. Similarly, tubes 25 and 26 are directly attached to the lid. 13 Also, the hoses 18, 19, 20, 21 are connected to the bottom of the case 12, characterized in that the strips of these tubes with lengths of webbing 30, 31, 32, 33 are extended, which are provided at their end with a beaded edge, the are secured by clamping means on the bottom of the suitcase. Similarly, the tubes 18, 21, 22, 23 and 24 with the aid of tissue lengths 42, 43, 39, 40, 41 are attached to the lid. 13

p0041Since the strip always oppositely located to a hose, the tubes of the lowermost layer are not connected to the layer lying on it, but with the film because the bar. In this way, the tubes 15 and 22 by a web fabric 34, the tubes 16 and 23 connected by a web fabric 35 and the tubes 17 and 24 by a web fabric 36th The webs are secured to the respective strips of the respective tubes. In the same way the hoses 19 and 25 and the hoses 20 and 26 are connected by webs 37 and 38th Characterized in that the axes of the tubes of successive horizontal layers extend opposite each other offset, producing a dense stacking, which contributes to the dimensional stability of the Notwasserwehres eleventh The fact that the connections between the tubes to each other and the connections between the tubes and the lid and extend vertically between the tubes and the case arises, a safe, water weir effect of Notwasserwehres 11. Here are the hoses and the connections between them in the way is to be prepared as the tubes 50 or 55 of figure 1A or 1B described. It is not necessary but desirable that the vertical links 31 to 41 are waterproof.

p0042Figure 2 is a schematic representation of the Notwasserwehres 11, wherein the tubes are given a circular cylinder on average. In reality, the hoses will not be filled under such high pressure that they are circular cylindrical in average. There are then length-shaped flattened contact areas between the tubes and between the tubes and the lid or the suitcase. In order to obtain a sufficiently high form stability, the compounds 30 to 41 are then ready to be shorter than in FIG. 2 At the same time, the upper edges of the case 12 will be rounded so that the hoses 18 and 21 to a greater extent have a circular cylindrical diameter.

p0043To counter vandalism and theft of the hoses, the Notwasserwehr has 11 two shields 14 both sides, which consist of a plastic fabric, possibly reinforced with steel wires or wires made of another material having a high strength such as carbon fiber or aramid fiber. In non-used condition of Notwasserwehres these shields are added to the trunk 12th

p0044The pyramidal structure of the tubes of Notwasserwehres 11 high, dimensionally stable Notwasserwehr is obtained using a small number of tubes.

p0045In the embodiment shown, the tubes have a diameter of about 1000 mm. The Notwasserwehr 11 is therefore suitable above the dike 10 for the weirs of water at water levels up to about 2 m.

p0046It will be clear that the number of tube layers and thus the number tubes per shift and the diameter of the tubes for a Notwasserwehr with the same or a different level in the filled state of the tubes can be chosen differently. To support the lid, the top layer is preferably made of at least two hoses.

p0047The cover 13 is for permanent use of the top of the dike gain in non-used condition of Notwasserwehres 11, for example, for traffic and transport purposes. The hoses can have a length of 500 to 1000 m, and the cover 13 can be incorporated as steel plate have an equal length. The tubes can also have a shorter length. The tubes are filled at one end thereof by a pump with water and are thereby inflated to a progressive manner from this page. Through the inherent elastic deformability of the steel plate of the lid 13 is then also pressed on progressive manner upwards. However, the cover 13 can also be made shorter pieces consist steel plate, which are interconnected by hinges.

p0048Figure 3 shows a Notwasserwehr 60, which largely corresponds to the Notwasserwehr 11 of Figure 2; like parts are then provided with same reference numerals. Only the vertical links 30 to 41 of Figure 2 have been replaced by the substantially diagonal connections 61-74. Thereby, the tubes can be connected to their strip each other directly, so that less material is needed. This substantially diagonal connections, the tubes are pressed by the pressure of struggling to water in its nested position.

p0049Figure 4 shows a Notwasserwehr 101, which is similar to the Notwasserwehr of Figure 2, but which has the purpose of being incorporated in a quay 100, and therefore must be as narrow as possible. Given the topmost layer tubing has only a hose 111th

p0050Notwasserwehr 101 has a case 102, which is relatively low and is completely filled by two tubes 105, 106 in fluid-filled state. Because on top are when filled three hoses 106, 107 and 108, on two tubes 109 and 110 and the end of the top tube 111. On the upper tube 111 of the lid rests 103. The lowermost tubes 105, 106 are connected to the bottom of the suitcase connected at 120, 121. Further, the tubes excellent strip material 122 to 129 as described in figure 1, for interconnecting and for connection with cover 103 and case 102, just as in the Notwasserwehr of figure 2. also this Notwasserwehr 101 has two shields 104 attached to both sides, and are also a number of cable drawing or bands 130, 131, 132, 133, so that the tubes 106 and 107 are received during idling or emptying thereof within the case.

p0051When using the Notwasserwehres 11, 60 or 101 must be ensured that the resultant of the horizontal force of about struggling water and the vertical force of the weight of Notwasserwehres itself runs through the central part of the base of the Notwasserwehres. The weight of the (concrete) koffers also plays a role 12. If the resultant force does not pass through this central part, the Notwasserwehr with suitcases and everything can tilt from the dike or quay under the influence of the pressure of Kraftes to struggling water.

p0052In use can all Notwasserwehre to increase the stability, the pressure in various hoses a different value be added. The tubes are filled in its effective state with water, and possibly part with a solid, granular substance such as sand.

p0053For inspection of Notwasserwehres 11, the lid, if need locally, be released so that they depend on the lid and the hoses are equipped with inspection hatches to control the hoses from the inside for leaks. For inspection of the tubes can also be filled with air. This creates the possibility of the hoses by one or a few in a striped coupled, vertical row to fill one at the same time and to inspect from the side, for example, for water leaks.

p0054Instead of hoses of textile material, the tubes can also be made of extruded tubes made of fiber-reinforced plastic material.

p0055Thus, the invention is a Notwasserwehr gain that can be mounted either temporarily at the desired location, or is permanently available on its site of use, and provides a dimensionally stable weir below using as little material possible. For effective in the state bringing the water weir little manpower is needed.

p0056It will be clear that the Notwasserwehr is not only suited for Notwasserwehr dikes or wharves, but also as to Notwasserwehr example houses or factories in a flood plain, or as a defense of polluted liquids such as fire water on factory sites. It even light traffic on the upper lid is possible.
