Description
<p>I</p>
<p>A Filled Bag For Providing Part Of A Temporary Barrier To Water</p>
<p>Background of the Invention</p>
<p>The present invention relates to a filled bag for providing part of a temporary barrier to water, and a method of manufacturing a filled bag.</p>
<p>For many years it has been known to construct temporary barriers to water from sandbags. The sand is both heavy and bulky, and therefore there are problems with storage and transportation to locations where the io water barrier is required.</p>
<p>In recent years an alternative filled bag has been produced which contains a super absorbent polymer, or S.A.P. When dry, the S.A.P. is light and of relatively low volume, and therefore storage and transportation problems are reduced. When immersed in water, the S.A.P. swells up to fill the bag, and thus the bag becomes a useful size when building a barrier. A problem with such S.A.P. filled bags is that the walls of the bag tend to balloon outward under pressure from the expanding S.A.P., the bag takes on a rounded shape and consequently becomes an unstable shape for building. I.e. as the bag is rounded it tends to roll.</p>
<p>Brief Summary of the Invention</p>
<p>According to a first aspect of the present invention, there is provided a filled bag for providing part of a temporary barrier to water, comprising: a water permeable envelope; a granular material located within said envelope, said material being of a type which absorbs water and swells up; and connecting means for connecting opposing parts of said envelope, such that said granular material surrounds said connecting means, whereby when said bag is immersed in water and said granular material swells to fill said envelope, said connecting means holds said opposing parts of said envelope together to provide said envelope with a shape that is stable on a flat surface.</p>
<p>According to a second aspect of the present invention, there is provided a method of manufacturing a filled bag for providing part of a barrier to water, comprising the steps of: obtaining a granular material which absorbs water and swells up; putting said granular material within a water permeable envelope and closing said envelope; and connecting opposing parts of said envelope, to provide said envelope with a shape that is stable on a flat surface when said granular material is swollen by immersion in water.</p>
<p>Brief Description of the Several Views of the Drawings Figure 1 shows a filled bag 101, along with a pile of other similar bags 102; Figure 2 shows a cotton sheet 201 on top of a hessian sheet 202, being folded in half to form a double-walled envelope envelope; Figure 3 shows the folded sheets 201 and 202 sewn together, along their short edges 203, 204 and another edge 301 to form an open-ended envelope 302; Figure 4 shows water absorbent material 401 being poured into the open-ended envelope 302 through an opening 305; Figure 5 shows the bag 101, after completion by strong stitches 501 in the centre of the envelope; Figures 6 and 7 show respectively a perspective view and a cross-sectional view of the bag 101 after immersion in water; Figure 8 shows the bag 101 in cross-section resting in a stable manner on another similar bag 801; Figure 9 shows an alternative filled bag 901; and Figure 10 shows partly assembled component parts of the bag 901.</p>
<p>Written Description of the Best Mode for Carrying out the Invention Figure 1 A filled bag 101 is shown in Figure 1, along with a pile of other similar bags 102. The filled bag 101 is suitable for use with other similar bags to build a temporary wall for use as a barrier to water.</p>
<p>The bags 101, 102 have a water permeable envelope containing a granular material of a type which absorbs water and swells up. The bags 101, 102 are shown in Figure 1 in their dry state, and consequently the granular material takes up a comparatively small volume. Thus, the bags 101, 102 are easily stacked and take up a relatively small amount of storage space when compared with sand used to fill traditional sandbags.</p>
<p>Figures 2, 34 and 5 A method of manufacturing the filled bag 101 is illustrated by Figures 2 to 5.</p>
<p>The bag 101 has a double wall comprising tough coarse woven fabric outer wall and an inner wall of a finer woven material. In the present case, the outer wall is made from hessian, while the inner wall is made from cotton.</p>
<p>Thus, the first step in making the bag 101 is to cut out a rectangular sheet of hessian and a rectangular sheet of cotton material of the same size. In the present example, the sheets are 60 centimetres by 74 centimetres.</p>
<p>The cotton sheet 201 is then placed directly on top of the hessian sheet 202, such that their corresponding edges are aligned, and then the two sheets are folded in half as shown in Figure 2. Thus, the short edges 203 of the sheets are positioned alongside the opposing short edges 204.</p>
<p>The folded sheets 201 and 202 are then sewn together, using jute yarn, along their short edges 203, 204 and another edge 301 to form an open-ended envelope 302, as shown in Figure 3. Thus, open-ended envelope 302 is rectangular and has two sides formed from edges connected by stitching 303, a third side formed by a fold 304 in the sheets and a fourth side providing an opening 305.</p>
<p>It may be noted that the edges of the two fabric sheets are sewn together using an overlock stitch to prevent either of them from fraying.</p>
<p>Water absorbent material 401 is then poured into the open-ended envelope 302 through the opening 305 as shown in Figure 4. The water absorbent material is a super absorbent polymer (S.A.P.), which is a free-flowing granular material having a similar appearance to fine white sand. An example of the super absorbent polymer which may be used is Degussa/Stockhausen Favor-Pak 230. For the size of bag in the present example, a 130-gram quantity of super absorbent polymer is used.</p>
<p>With the super absorbent polymer enclosed within the envelope, the opening 305 is sewn up to produce a closed envelope 502. Thus, the polymer is contained within the inner wall of the double walled envelope.</p>
<p>It may be noted that while the coarser hessian outer wall provides the bag with a hard wearing outer surface, the finer cotton inner wall has a sufficiently fine weave to prevent the polymer grains from escaping.</p>
<p>The bag 101 is then completed, as shown in Figure 5, by making a number of stitches 501 in the centre of the envelope, i.e. 30 centimetres from the ends and 18.5 centimetres from the sides of the envelope, joining the back and front faces of the envelope together. The stitches 501 are made using a jute yarn, of the type used to sew the edges of the envelope together. In the present embodiment the stitches are arranged in a block approximately 20 millimetres in length and 5 millimetres wide. However, they may be arranged in blocks of other formats, such as 10 millimetres by 10 millimetres, but to provide sufficient strength, the block has an area of approximately 1 cm2 (1 square centimetre) or more.</p>
<p>In an alternative embodiment, the stitches 501 are replaced by an alternative means of connecting the opposing faces of the envelope together. For example, in one embodiment the front and back of the bag are tied together in the middle of the envelope. In this case, the stitches 501 are replaced by a loop of strong twine which passes through the envelope from front to back, then back to front and tied at the front. For the purposes of providing sufficient strength to the tie, the loop is arranged to enclose at least three of the warp or weft threads in each of the outer hessian walls of the envelope. However, in each case, the finished bag 101 comprises a sealed envelope having two opposing faces connected at their centres by a connecting means such that the super absorbent polymer granules surround said connecting means.</p>
<p>In alternative embodiments, the faces of the envelope are connected at more than one position. For example, in some embodiments the envelope is arranged to have a length that is much larger than its width, and the front and rear faces of the envelope are connected at several positions spaced along the length of the envelope.</p>
<p>Figures 6 and 7 The bag 101 is typically used with other similar bags to build a barrier to hold back water, for example flood water caused by excessive rain fall. To use the bag 101 it is first immersed in water. The water penetrates the double wall envelope of the bag and is absorbed by the super absorbent polymer granules. The granules expand and fill the bag such that the walls tend to balloon outwards. However, while other parts of the envelope walls are forced outwards, at the location of the stitches 501, the stitches hold the opposing faces of the envelope together.</p>
<p>The bag 101 is shown in the perspective view of Figure 6 and a cross-sectional view in Figure 7 after immersion in water. The cross-section of Figure 7 passes through the bag's stitched side 204, its central stitches 501 and its folded side 304.</p>
<p>As will now be understood from the preceding description, the bag 101 comprises a double-walled envelope 502 containing a water absorbent granular material 401. The opposing faces of the envelope are held together by stitching 501 at a substantially central location to provide the swollen bag, as shown in Figures 6 and 7, with its shape.</p>
<p>The stability of the swollen bag 101 on a flat horizontal surface 701 is demonstrated in Figure 7. As the stitches 501 hold the upper and lower faces of the envelope together, the absorbent polymer 401 is only able to push out the envelope walls surrounding the stitches and not at the stitches themselves. Consequently, instead of the lower face of the bag having a simple domed shape, it has a substantially circular ridge having a depression 703 in the middle. Thus, because the bag rests on a relatively broad circular ridge, its position on the surface 701 is stable.</p>
<p>Figure 8 Similarly, when the bag 101 is positioned on other similar bags to produce a wall for use as a water barrier, its position on those bags is also stable. Thus, by way of example, the bag 101 is shown in cross-section resting in a stable manner on another similar bag 801 in Figure 8.</p>
<p>Figure 9 An alternative filled bag 901 is shown in Figure 9. The bag 901 is similar to bag 101 in that it includes stitching 902 attaching the rear wall of its outer envelope to the front wall, such that water absorbent granular material surrounds the stitching to provide the envelope with a shape that is stable on a flat surface. The differences of the bag 901 from the bag 101 are in the manner in which the internal walls of the envelope are attached to the outer walls. This is illustrated by Figure 10.</p>
<p>Figure 10 Component parts of the bag 901 are shown partly assembled in Figure 10.</p>
<p>To manufacture the bag 901, sheets of cotton and jute are first cut out as for bag 101. However, the next step is to fold the cotton sheet in half and sew 1001 around two edges to produce an envelope 1002 having an open end 1003. A measured quantity of super absorbent polymer (S.A.P.) is then put in the cotton envelope and said envelope is shaken to ensure that the S.A.P. is at the bottom. The cotton envelope 1002 is then laid on one half of the jute sheet 1004, such that the open end 1003 of the cotton envelope projects past the edge of the jute sheet (typically by 5 millimetres) and the sewn sides are just inside the other edges of the jute (typically by to 20 millimetres). This arrangement is shown in Figure 10.</p>
<p>io The protruding open end 1003 of the cotton envelope 1002 is folded over and the uncovered half 1005 of the jute sheet 1004 is then folded over the inner envelope. The jute envelope is then stitched around its three open edges with overstitch so as to close the inner envelope in the end-seam.</p>
<p>Thus, a this stage, the inner envelope 1002 is only attached to the outer envelope along one edge.</p>
<p>The bag 901 is then completed by stitching 902 (or alternatively by tying) in a similar manner to bag 101.</p>
