DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

[0025] It is understood that particular embodiments of self-filling flood-protection bags according to the invention are shown for illustrative purposes only and not as limiting technical solutions. Persons of skill in the art will find or will be able to find out under use of more or less routine experimentation, many equivalents of specific embodiments of self-filling flood-protection bags according to the invention. Also such equivalents will then be falling into the extent of the following patent claims. To the skilled persons in the art, they can-not encounter any difficulties dimensioning of such self-filling flood-protection bags, and suitable choice of materials and structural arrangements, thus these characteristics are not solved in details.

Example 1

[0026] In this example of a particular embodiment of the subject of invention there is described a first arrangement of a self-filling flood-protection bag, as shown in FIGS. 1 and 2. This self-filling flood-protection bag consists of two enclosed chambers 1, that are interconnected by terminal yoke 2 in the form of a letter T and that are made of polyester fabric with high water absorbing capacity. Chambers 1 are filled up with granular or jelly mixture of water superabsorbents 3 based on cross-linked polyacrylates: polyacrylamide copolymers and polyacrylic acid together with polyvinylpyrrolidone. Terminal yoke 2 in the form of a letter T contains two handling metal eyelets 4. In FIG. 3 is shown a built-up flood-protection wall. It consists of self-filling flood-protection bags stacked on each other, where can be seen innovative function of terminal yokes 2, that provide stability, but also watertightness of stacked self-filling flood-protection bags, because terminal yokes 2, from one row, create gaps into which are occupied by chambers 1 of lower and higher row of stacked self-filling flood protection bags.

Example 2

[0027] In this example of a particular embodiment of the subject of invention there is described a second arrangement of a self-filling flood-protection bag. This self-filling flood-protection bag is sufficiently described in the foregoing example. The difference consists only in the form of absorbent. In this case chambers 1 are filled-up with moulded water superabsorbent 3 in the shape of a latticed band. Another difference consists in that the terminal yoke 2 is made of plastic.

Example 3

[0028] In this example of a particular embodiment of the subject of invention there is described a third arrangement of a self-filling flood-protection bag. This self-filling flood-protection bag is sufficiently described in the foregoing example. The difference consists only in the number of three chambers 1 interconnected by two terminal yokes 2 of self-filling flood-protection bag. Terminal yoke 2 in the form of a letter T contains three handling metal eyelets 4.

INDUSTRIAL APPLICABILITY

[0029] The self-filling flood-protection bag according to the subject inventions finds application in the area of water-supply management for the construction of flood-protection dams and barriers and building industry for drying of sloppy and wet spaces.
