Definitions

  • the present invention relates to a embankment device for delimiting liquid accumulations during for example floodings and other similar incidents of unpredictable type, (see e.g. US-A-5,971,661).
  • a flooding often involves damages on ground, buildings and constructions, on crops etc., and in order to limit these damaging effects one tries to limit the spreading of the liquid by means of embankments: barriers which are built up to a certain height on the bed over which the liquid spreads. In this manner, the liquid can be accumulated to a certain depth on the inside of the embankment, while the area outside the embankment at least to some extent is protected against the liquid flowing out.
  • embankment work usually takes on a nature of improvisation, one uses materials such as sandbags, loading pallets, which are propped up to an inclined position and covered with a plastic cloth or sometimes embankments which are shovelled-up.
  • materials such as sandbags, loading pallets, which are propped up to an inclined position and covered with a plastic cloth or sometimes embankments which are shovelled-up.
  • embankment To arrange a embankment in this manner is very irrational.
  • embankment devices which can be manufactured and kept in readiness and in this regard have a suitable form for storage, and which can be transported to the place of effort in a rational manner and rapidly be set up in order to adopt utilization condition and later on be easily removed and transported away and folded up for storage until next effort.
  • the invention relates to a embankment device, which fulfils all said demands.
  • it consists of cloth material, preferably some type of textile-reinforced plastic cloth, by means of which lengths of the material can be rolled up or folded up for space-saving storage.
  • lengths of the embankment material can subsequently be easily laid out by means of being unrolled or unfolded in order to be joined together to the necessary length.
  • the laying out on the bed can take place from vehicles or even from aeroplanes, so that the transportation forward and the laying out can take place in direct connection with each other.
  • the setting up of the cloth material after the laying out, with the purpose of forming the embankment can also take place in a simple manner with a small work effort.
  • the removal is also easy and when the material has been folded up, it can be transported away for storage and utilization at the next work effort.
  • the cloth material has been arranged to constitute the main part of a bearing construction as well. This is accomplished by means of the fact that the cloth has been joined together in order to form upright pockets in which the liquid can flow when it rises at the inside of the embankment.
  • a certain propping up is required in such manner that the pockets are at least partly opened in the direction of the liquid which flows towards said pockets.
  • Such a supporting structure can be composed of bar-formed elements, which can be joined together with the cloth material during setting-up and be laid into the same during disassembly when said cloth material is rolled up or folded up in order to adopt its storage and transportation condition.
  • other types of bearing structures can also be utilized.
  • the object of the embodiment is to make the material for the embankment device easy to store and transport, easy to lay out and set up and once again be folded up.
  • the construction is very material-saving and by means of the fact that the embankment device can be used several times and is so rational to handle, a large cost-saving is obtained compared with such methods which up till now have been used in order to provide embankment devices for protection during unexpected flow of liquid.
  • a cloth material and preferably such a material which is non-permeable to liquid, such as resistant plastic sheeting or fabric-reinforced plastic cloth, forms a bottom layer 1, which is intended to rest on the bed 7 over which the liquid can be expected to wash.
  • a number of walls 2 of the cloth material raise so that a number of pockets 3 forms.
  • the height of the walls increases from a side 5 of the embankment, which is intended to face the side from which the liquid is expected to flow, in the following called the inside 5.
  • the outermost wall 6 at the opposing side 9 of the device which in the following is called the outside, is the highest and the height of the intermediate walls 2 increases gradually, so that a line over the tops of the walls forms an angle to the bed 7. This implies that the pockets 3 become gradually deeper from the inside 5 to the outside 9.
  • the drawing also shows an anchoring of the protruding part of the bottom layer 1 at the inside, by means of a ground mounting 14 which is driven down into the bed.
  • Fig. 2 shows a top view of the structure formed by the cloth material, where the upright walls 2 are apparent. Furthermore, it is shown that the walls 2 are joined with transverse walls 8, so that the pockets 3 can be said to form a cell structure.
  • the transverse walls 8 are also intended to be of cloth material.
  • a suitable material is plastic sheeting or fabric-reinforced plastics. In that respect, welding plastic pieces together suitably forms the described structure.
  • the material 1 in the bottom layer can be double-folded gradually and welded together in double layers in order to form the walls 2.
  • the material stretches outwards in a single layer from the inside 5 to the outside 9.
  • the walls 2 can obviously be formed by plastic strips, which are welded onto the bottom material.
  • the intention of the described structure is that liquid, which gradually washes in from the inside 5 concurrently with that the liquid rises, fills the pockets 3 to the height which the liquid surface reaches. In this connection, it pours into the pockets from above concurrently with that the liquid surface rises.
  • the walls 2, apart from the first at the inside and the last at the inside 9, can be provided with limited openings, so that pockets, the walls of which extend over the liquid surface, also are filled up to the same.
  • Figs. 1 and 2 show how rigid bars, in the following called the supporting elements 10, in the first embodiment are joined with the external edges of the walls 2 at the same time as the ends of the supporting elements which face the inside 5, which ends are provided with cushion plates 11, rest against the bed 7 via the bottom layer 1.
  • the supporting elements 10 are supported by oblique struts 12, which also are supported by the bed 7, they are shown when they are stuck down into the same.
  • bar-formed posts 13 which meet the respective supporting elements and the struts in a common point.
  • a connection member 15 is arranged, which can be a body with holes in different directions into which the ends to the supporting elements, the struts and the posts can be stuck.
  • connection member can also be provided with joints, so that the struts and the post can be folded over to a position which is parallel to the supporting element.
  • the object of such an arrangement is to make it possible to fold up the soft cloth structure so that it adopts a flat condition by means of being rolled up or folded up, and in that case it is desirable that the bar-formed elements can be placed above the cloth structure which has been laid down and that they can be integrated in the roll or the folded-up bundle so that they lie crossways to the longitudinal directional of the device.
  • the main element in the support structure is formed by the supporting elements 10. They keep all the walls 2, 6 and 8 upright. Before the pockets are filled, the supporting elements only have to carry the weight of the material in the walls under the respective element. It has been shown that even when the pockets are filled with liquid, a comparatively small force is required to keep the walls upright. However, as has been mentioned, the stability is smallest at the wall 6 which is farthest out towards the outside 9 and for its outer side additional supporting measures may be required.
  • the posts 13 constitute support for the external wall at certain distances from each other. If additional support should be required, the support structure of the bars can be supplemented with bars, which extend between the posts crosswise or in parallel with each other.
  • Fig. 3 which shows the second embodiment, the cloth structure with the walls 2, 6 and 8 is approximately the same as the one which has been described previously.
  • an inflatable supporting element 20 of an airtight material has been added. It has a cross-section with a triangular form with a wider base and a narrower top against which the supporting elements 10 rest. It has an elongated form and by means of this, it constitutes support for the external wall 6 to the outermost of the pockets 3, and the one side of it which faces the pocket may constitute this particular external wall.
  • the supporting element 20 in divided up into several cells by means of partition walls 21, which provides the element with stability, so that it can not fold up when it is filled with air.
  • the embankment device When the embankment device according to this embodiment is set up, equipment for inflating the supporting element 20 is required. If such equipment is present, the embankment device can be raised much quicker than if bar-formed supporting elements are used which shall be raised when the strip of the folded cloth material has been rolled out.
  • FIG. 4 One manner of supporting the walls 2 between the supporting elements 10 as well is illustrated in Fig. 4.
  • the reference numeral 22 indicate lines, which each extends along the entire longitudinal direction of the respective wall and which can be provided with a certain tension between the supporting elements in order to form a support along the upper edges of the walls.
  • the drawing also shows how the walls can be provided with floating elements 23, which are constituted by double-wall sections with floating material such as cork or cellular plastic or which are filled with air in connection with the laying-out. If an inflexible material is used as floating body, this must be divided up into smaller sections, which allows the embankment device to be rolled up or folded up to adopt the storage and transportation condition.
  • connection element is required, which in Figs. 1, 2 and 4 is indicated by the reference numeral 24. It can consist of an eyelet which is inserted at the upper edge of the wall or a mounting, which lies over the supporting element and by means of a lower part is attached to the upper edge of the wall.
  • connection elements there is no possibility for the connection elements to glide along the supporting elements but they are instead fixed to the spot where the wall in question should be situated.
  • a line the line 22
  • the connection elements are fixed to the line.
  • the rigid supporting elements 10 are provided, which supporting elements keep the cloth walls of the pockets upright by means of being joined with the upper edges of these.
  • a certain stiffening can be obtained by means of the cloth material being stretched while points of attachment at the bed are utilized.
  • This manner of propping up is utilized for the third and fourth embodiments according to Figs. 5-7.
  • the same reference numerals which have been used in Figs. 1-4 are to some extent used.
  • the transverse walls 8 are arranged in such manner that they can form a straight line by means of their upper edges, which line in Fig. 5 is indicated by the reference numeral 31, which represents an stretchable material band.
  • the reference numeral 31 which represents an stretchable material band.
  • Such stretchable material bands shall be provided crossways to the device with some intervals.
  • ground mountings 14 has been indicated for holding down the front edge of the bottom layer 14 at the inside 5 of the device.
  • a mounting 14 is also provided where the lower end of the material band meets the bed 7 on which the bottom layer 1 rests.
  • said internal mounting must have a large resistibility against being pulled up from the bed, since it is going to constitute the point of attachment for the lower end of the material band.
  • a bar-formed supporting element 32 is provided. This is joined with the bottom layer at its external edge, suitably by means of the element 32 being stuck down into the bed 7 through an eyelet 33 in an extruding lip of the bottom layer. Furthermore, at the lower edge, the element 32 is provided with a supporting plate 34, which shall rest against the bed and prevent that the element 32 sinks down into the same. Furthermore, at its upper edge, the element 32 is provided with a hook 35, which on the one hand is joined with the rear wall 6 of the outside at its upper edge in order to keep it upright and on the other hand constitutes point of attachment for the upper end to the material band along the line 31.
  • An additional ground mounting 14 is driven down into the bed 7 outside the device and constitutes the point of attachment for a line 36 which is connected with the upper end of the element 32.
  • the line is stretchable by means of a mounting 37.
  • the material band can be provided with a more or less hard stretching.
  • the stretching forces must not result in that the upper point of attachment moves inwards, thus that the element 32 inclines inwards from the intended position. This is however prevented by means of the force from the stretched material band being neutralized by the stretching of the line 36.
  • the bar-formed element 32 too obtains a certain propping up in the longitudinal direction of the device. To some extent, such is obtained by means of the connection with the rear cloth wall at the eyelet 33 and the hook 35. In that case, the cloth wall can be provided with certain reinforcements, which decrease its flexibility, though not to such extent that the possibility of rolling up is impaired. Moreover, propping up in the longitudinal direction can also be obtained by means of two stretching lines 36 being arranged at an angle with each other.
  • the fourth embodiment has great similarities with the third embodiment, see Fig. 7.
  • an upper straight line is provided, which here too is indicated by the reference numeral 31, where a material band can be formed by means of upper edges to transverse walls or a particular material band in the form of, for example, a line.
  • an internal ground mounting 14 with a strong mounting in the bed 7.
  • the external edge of the device is also anchored to the bed by means of an external ground mounting 14.
  • the rear wall is provided with some sort of vertical stiffening, such as a number of bar-formed elements 40.
  • the elements 40 are not, like the supporting element 32 in the third embodiment, provided with any stretching device for keeping them upright.
  • the object of the rigid elements 40 is principally to make sure that the rear cloth wall 6 does not curve outwards and collapse.
  • the propping up is improved during liquid-filled condition; if the wall 6 should tend to fall backwards, this will stretch the material band along the line 31 between the upper edges of the rigid elements and the internal ground mounting 14 and keep the device in balance in the position which is shown in Fig. 7, where the liquid surface inside the embankment device is indicated by the reference numeral 41.
  • Fig. 6 There are different ways of keeping the mouths of the pockets opened to some extent as is shown in Fig. 6. If the cloth material has a certain rigidity, which can be presumed, it can be made-up so that it strives to position itself in the position which is shown in Fig. 6, if it is not pressed together by means of some external force, like the one which arises during rolling-up.
  • One alternative is to insert compressible material volumes, for example by foam plastic, between double cloth layers, so that the foaming material strives to open the pockets by means of its elasticity, such as is shown in Fig. 6.
  • a line which runs along the device can be provided, which line is attached to the cloth material in the upper corner of the device, thus the meeting point between the straight line 31 and the rear wall 6. If this line is slightly stretched between raised points of attachment, a certain opening of the pockets is obtained.
  • the fourth embodiment is the simplest as its support structure mainly is reduced to the elements 40. Nevertheless, it should be able to provide the required embankment effect, particularly if the liquid flows slowly.
  • the embankment device is constructed in the form of module elements, for example of some ten or hundred metres in length, so that the device of the embankment arrangement can be adjusted to the present circumstances. In that respect, it is necessary that the different modules can be joined to each other.
  • a joining device can be arranged is apparent from Fig. 8.
  • Fig. 8 it is shown how the cloth material covers the entire cross-section as a gable 25 and how it has been unfolded and joined together in order to form a flange 26 around the cross-section of the structure, which is formed by the bottom 1 and the walls 2.
  • a large number of holes 27 are provided. These are intended to be used during the joining of the flanges into two modules which meet each other.
  • Another possibility is joining by means of pins, which are stuck into the holes and attached by means of a fixed head being arranged at one end of the pin and a head which can be snapped on being arranged at the other end.
  • the pins, as well as the heads which can be snapped on can be provided on long bands with a separation, which is adjusted to the separation of the holes 27.
  • embankment elements with obliquely cutoff ends are also provided.
  • Fig. 9 shows a module 28 whose gabled ends terminate in an angle of 45°, thus with an angle of 90° in relation to each other.
  • the module 28 is shown inserted between two straight lengths 29 and 30, wherein the embankment arrangement here forms an angle of 90°.
  • the supports at the outside 9 of the device is first removed, wherein the cloth structure collapses and can be flattened out against the bed 7.
  • the bar-formed supporting elements which form part of the support structure will lie above the cloth structure crossways to the longitudinal direction of the device.
  • the first embodiment with the struts 12 and the posts 13 these are removed from the connection elements 15 or lowered down from the same in a position which is parallel to any existing supporting elements, depending on how the connection element is formed.
  • the entire strip of the collected cloth structure can be rolled up or folded together with all the bar-formed elements which have been inserted.
  • rigid elements are provided only for supporting the outside 9 of the cloth wall.
  • the first step of the folding-up will be to empty the element of air and to lay it flattened out together with the cloth structure which has been laid out against the bed.
  • rolling-up or folding-up can take place.
  • the embankment arrangement consists of several embankment devices which have been joined together, it is suitable that these are taken apart and particularly if elements 28 (see Fig. 9) are installed, which are intended to form angles.
  • the embankment devices When the embankment devices shall be utilized once again, a suitable number of straight lengths and angular devices are transported to the site of the placing, and are unrolled or unfolded on the bed. Next, the devices are raised after any existing supporting elements and required ground mountings 14 have been provided, alternatively by means of inflation of the supporting elements 20. As the liquid rises gradually at the inside 5 of the embankment devices, the pockets 3 will be filled and provide such stability to the devices that they are capable of resisting the pressure from the liquid inside the embankment.
  • the part of the embankment device which requires volume consists of cloth material which by means of its design, with pockets or cells, which can be filled with liquid, provides a stability to the device.
  • an initial propping up is required.
