Abstract

Container made of water-permeable fabric consisting of high modulus, synthetic threads comprises at least one filling opening (9) for washing in earth or sand. The fabric is impregnated or coated so that the thread length of the fabric is stabilized and the water-permeability of the fabric is reduced only enough to enable washing in of the earth particles over large distances and drainage of the washed-in earth over the entire container. Preferred Features: The fabric is coated with plastic mixed with UV-stabilizers. The coating is formed by a thin film forming openings or pores over the entire surface. The fabric is coated with a plastic film in which water-soluble granulates, e.g. salt, are uniformly distributed over the surface. The fabric is coated with a water-soluble film consisting of adhesive, gelatin, etc.

Description

The invention relates to a container made of water-permeable Fabric made of highly modular synthetic threads with at least one fill opening for flushing in soil or sand and at least one water outlet.

Such, preferably tubular containers with a diameter 0.8 to 5 m are particularly required in coastal hydraulic engineering, for example for the construction of cracks, as a flushing area limitation or for Raising a dike. Sand, fine sand up to coarse silty soil, e.g. Watt floor, washed in. It continues from Inlet sand in the tubular container until one from the inlet to the Outlet extending flat gutter at the apex of the hose remains.

The well-known tubular container made of water-permeable fabric have the disadvantage that the permeability of the highly modular fabric so It is great that large amounts of water are required when flushing in sand and that with tubular containers at relatively short intervals Filler neck must be attached so that the container from the inlet to can be completely filled with sand or soil for water outlet.

To reduce water consumption, it is known to use a tubular Container to use sections of fabric that is completely waterproof is. Such containers have the disadvantage that the flushed bottom or sand in areas where the fabric is waterproof is not sufficient can drain.

Furthermore, known containers have the disadvantage that they are more heavily loaded Placing the tubular container move the threads of the fabric, which causes considerable water losses during the rinsing process. These thread shifts in the fabric can also cause erosion, so that the container is not sufficiently filled with sand or soil can be.

The invention has for its object a fabric To create containers in which the thread position of the fabric is stabilized and in which the flushing of soil or sand with less water consumption is possible.

This object is achieved according to the invention in that the tissue is so impregnated or coated that the thread layer of the fabric stabilizes and the water permeability of the fabric at least temporarily is so reduced that on the one hand the washing in of the soil particles over large Stretching without major water consumption is possible and on the other hand a Drain the washed-in soil over the entire container can.

A container according to the invention has the advantage that for its manufacture a relatively permeable and displacement-sensitive fabric can be used can, which can be manufactured much cheaper than a denser Tissue. The coating, which the water permeability on a reduced optimal, predeterminable value, allows when filling, to work with much less water than with containers made of not coated fabric. The soil material carried by the water when flushing in can be transported over long distances before moving settles. This allows the distances to fill a very long one hose-shaped container required inductor significantly enlarged become. The reduction is particularly important when used under water of rinsing openings is an advantage because it is costly and time-consuming Moving the irrigation hoses is reduced.

In one embodiment, the fabric is coated or impregnated the invention with an aqueous plastic dispersion such that the threads stick together at the crossing points of weft and warp threads and the threads are covered with plastic.

The pores of the tissue are reduced and, if necessary, also partially closed. Because the pores of the tissue are even over the Tissue distributed, partially open, ensures that the dewatered sand or soil - albeit over a longer period of time can. A certain water permeability is necessary for the drainage of the flushed Material necessary. This can also result in a hydrostatic pressure be dismantled, which is advantageous for hydraulic engineering tasks.

The plastic coating or the plastic impregnation of the fabric causes a fixation of the thread layer, which causes a displacement of the fabric threads also in heavily used areas, for example as a result of Unevenness of the pad or in the area of the seams avoided become. The coating and impregnation of the fabric as well as the Covering the fabric threads with plastic protects the fabric against mechanical damage during installation and also offer protection against UV radiation, if UV stabilizers are added to the plastic become.

Advantageously, the fabric consists of multifilament threads that are in the Soak up impregnation with plastic dispersion.

The fabric can also be coated with an open-pore plastic film become. Furthermore, the fabric can also be made with glue, gelatin or another one that creates an adhesive connection but is water-soluble Material or coated with a plastic film by water-soluble Granules, e.g. Salt, evenly distributed over the surface are. When washing in and after washing in soil or sand these components dissolve, making the fabric permeable to water becomes.

Because of a tubular container with a relatively large diameter considerable forces are to be absorbed, a tissue is used in which the Warp threads predominantly run straight, while the weft threads Wrap warp threads in waves. In the tubular Containers run the load-bearing warp threads in the circumferential direction. The required to form a long hose and according to that respective circumference plus overlaps in the area of the longitudinal seam, 4 to 5 m wide pieces of fabric are covered with a J, butterfly or overcast seam joined together. The seam that the Connects fabric web pieces with each other, is expedient on the Arranged inside the container wall.

Overlap the ends of the tubular fabric pieces one another and are separated by several, arranged in the overlap zone, in Seams running together in the longitudinal direction of the tubular container connected. Because these seams on the opposite of the filler neck Side of the container are arranged and thus these seams Always on the ground, a large part of it is in the circumferential direction running tensile forces absorbed by the friction, which the loaded Has container wall with the bottom.

The tubular containers or those formed into a tube However, pieces of fabric web can also be stuck by overlapping one another of a first or front container or fabric web piece in one, in Sufficiently following the flushing-in direction of the tubular fabric web piece be tightly connected. At the construction site, for example done with eyelets and hooks.

The container can also be mat-like and rectangular in plan view be square and a lower fabric sheet and an upper one Have fabric sheet, the upper fabric sheet over spacers is connected to the lower fabric sheet. These mat-like containers can be formed in a known manner from a double fabric in which the lower fabric sheet and the upper fabric sheet at the edges and at individual places are woven together and the spacers are woven are.

The tubular container 1 according to FIG. 1 is made of several pieces of fabric web 2,3,4 composed. Each piece of fabric web 2,3,4 consists of high-modulus polyester fabric with a plastic dispersion like this is coated that the warp and weft threads are fixed and that the pores of the tissue are largely closed but still one Allow drainage of the washed-in soil. The tubular container can have a diameter of 0.8 m to 6 m or more. Dependent on the high-modulus fabric has a strength of 50 to 500 KN / m. The fabric can be made of polyester or other heavy duty synthetic yarn e.g. Polyamide, polyethylene, polypropylene and the like exist.

The plastic dispersion is, for example, a polymer dispersion, a aqueous styrene acrylate dispersion or polyurethane dispersion.

The plastic dispersion can be sprayed onto the Tissue or applied by immersing the fabric in the dispersion become. By squeezing the soaked tissue, the remaining one Plastic coating can be adjusted. As a result of the small Water loss between the inlet port 9 and the water outlet 10 the ground can fall over relatively long distances, for example 100 m Hose 1 can be flushed in.

2 shows, these ends 12, 13 overlap to form a tube shaped fabric sheet pieces 2,3,4 each other and are separated by several Seams 8 extending in the longitudinal direction of the hose 1 are connected to one another.

The tube pieces formed by the fabric web pieces 2, 3, 4 are over an inner, all-round butterfly seam 7 with each other connected.

This type of assembly enables the hose to be used on the terrain to adjust that it varies in diameter. The hose sections can be conical by the longitudinal seams 8 obliquely to the weft threads 6 run so that a hose section on one side, for example Diameter of 1.80 m and on the other side a diameter of 1.20 m.

The ends of the tubular container 1 are each one sewn-in lid 11 closed.

The fabric web pieces 2,3,4 consist of a fabric, the warp threads run straight and absorb higher forces with low elongation than the weft threads 6 that cross the warp threads 5 in a wave-like manner. The warp threads 5 of the fabric web pieces 2, 3, 4 run in the circumferential direction, while the weft threads 6 run in the longitudinal direction of the hose 1. to Forming a hose 1, for example 48 m long, will result in approximately 10 Tissue web pieces of 5 m width are required.

If longer hose lengths are required on site than can be handled, the hoses must be designed so that another hose can be reliably connected. To achieve this, be on the ends of the hose 1, the cover 11 sewn in such a way that a tissue protruded 14 from 0.5 m to 1 m remains. At this supernatant 14 can via an all-round seam 15, in particular a butterfly seam, the excess 14 of a further hose 1 can be connected. The Space between the cover 11 of the first hose 1 and the cover 11 the hose connected to it must be washed in with sand or soil in the second hose separately filled with sand or soil before the seam 15 is closed. However, this is the case with some Applications, e.g. under water, with considerable difficulties. However, at the end of the first hose and at the beginning of the part of a zipper sewn on the following tube, see above can the connection of two hoses 1 via a circumferential Zipper done. In this case, a lid 11 at the end of the first hose 1 or at the beginning of the next hose 1, so that a subsequent filling of an intermediate space is not necessary is.

So that the zipper is tight after closing, there is at least one Zipper half provided with a sealing strip, which is after the Closing the zipper on the inside of the zipper hangs up and seals it.

As shown in FIGS. 7 and 8, there is a first tubular container 1 'the end 18 in the rinsing direction is open, and this first container 1 'is inserted overlapping into a second tubular container 1 ", which is open at its end 19 opposite the flushing direction. The inserted end 18 of the first container 1 'is on its circumference connected to the inner wall of the second container 1 ". Also the front one End 19 of the second container 1 "should be on the outside of the first container 1 'are attached so that both containers are connected wrinkle-free and in Overlap area no loss of water and flushed sand occurs.

Attaching the end 18 of the first container 1 'to the inner wall of the in the washing-in direction of the following container 1 "can be sewn all around Gluing, riveting or by means of a zipper or Velcro or punctually using hooks and eyes, snaps or loops.

The overlap area 20 should be at least a quarter of the diameter the tubular container 1 ', 1 ", that is, with a diameter of 2 m at least 50 cm.

At the construction site, the connection by means of hooks 28 and eyes 29 is special easy to do. For this purpose, at the end 18 of the first tubular Container 1 'and at an overlap distance from the front end 19th of the second tubular container 1 "at equal intervals on Circumferentially distributes the corresponding hooks 28 and eyes 29 appropriate. The distances between these hooks 28 and eyes 29 may vary from the circumference of the tubular container 30 cm to 80 cm be. At the open end 18 of the first container 1 ', an additional stretchable textile strip 27 may be attached, which on the inside of the second container 1 "to be fastened edge of the first container 1 ' protrudes and the differences between the diameters of the containers 1 ' and 1 ". This stretchable textile strip 27 is made by the pressure of the washed-in sand against the inner wall of the second container 1 " pressed and pressed into possible cavities, so that even then erosion-proof connection of the two containers takes place when the second container 1 "is larger in diameter than the first container 1 '.

In Fig. 9 is a mat-like flat container 1 '' 'for flushing in sand shown, the lower and upper fabric web on the end face 21 and Back 21 'and on the sides 22 are interconnected. So that Flat containers 1 '' 'do not bulge when sand is flushed in Surface of the container 1 '' 'at regular intervals spacer 23 attached, which is the maximum distance between the lower and the Define the upper fabric web at certain points and only reduce bulging allow between the spacers 23.

Sand or soil are cleaned with the help of a induction pipe 25 or hose flushed. The outlet of the induction pipe 25 is along the center line of the container 1 '' 'slidable, so that between the outlet and the in Area of the front wall 21 and rear wall 21 'located water outlets a current is created which causes sand or soil to be washed in. During the induction, the induction pipe 25 becomes corresponding to the degree of filling of the flat container 1 '' 'withdrawn. In the embodiment 9 is the water outlet or the water outlets of Drain strips 24 are formed, which are filter stable and the washed in Retain sand, but one against the rest of the container wall have increased water permeability. The drain strip 26 is preferred a fabric that is at a distance from the filler neck or at a distance from the Slidable outlet of the induction pipe or hose 25 in the area of Front or back 21 in the top of the flat container upper fabric sheet is sewn in. The drain strip 24 can also extend into the upper region of the end wall 21 and rear wall 21 '.

10 to 13 show embodiments of the tubular container 31,32, which are designed so that they are easily and quickly coupled to each other can be. 10 shows a first container 31 on one End a substantially cylindrical, elastic, but also stiff Tire 33 on. The thin-walled casing of the container is on this tire 33 31 fastened as possible without folds. The attachment can vary depending on the material by gluing or welding the inner tube to the tire or by Wrap the tire through the container cover. At the beginning of the coupled second container 32 is the same in diameter cylindrical tire 34 attached, due to its elasticity by the Tire 33 can be inserted into the end region of the first container 31 and by retracting the coupled container 32 with its inner edge against the inner edge of the tire 33. Depending on, like the thin-walled casings of the containers 31, 32 on the tires 33, 34 11 are attached, as shown in FIG. 11, the tires 33, 34 directly one on top of the other, or - as shown in FIG. 12 - there is a thin container wall between.

To maintain a tight seal at the coupling point, you can on be attached to the outside of the container 31,32 means that an attachment the tire cause 33.34. For example, after withdrawing the coupled second container 32 via the coupling point a band be glued on, the end portion of the first container 31 and the The starting area of the second container 32 is fixed in its position relative to one another. Also, the ends of elastic bands that are under tension stand, are attached to the outer surface of the two containers 31,32. These elastic bands press the tires 33, 34 against one another.

To close a container 31 or 32 is a lid 35, which also is provided with a tire 36 of the same size and which accordingly a tubular container 31 or 32 can be attached.

As shown in FIG. 13, the tires 33 ', 34' can also be slightly conical be trained. This version has the advantage that the conical tire 34 'of the coupled container 32 clamping in the conical tire 33' can be inserted, creating a greater tightness at the Coupling point is achieved.

The tires 33, 33 ', 34, 34', 36 can be made of sheet steel or plastic. The stiffness of the tires and their thickness depends on the diameter the container. The larger the diameter, the stiffer and the tires 33, 33 ', 34, 34', 36 can be thicker. The cross section of the tires can be rectangular, oval, wedge-shaped or round.
