Description

Flood barrier element

Technical field

The technical solution relates to a flood barrier element for retaining flood water during floods and floods, in particular an element consisting of a simple cylindrical water-filled connectable body made of a waterproof material.

BACKGROUND OF THE INVENTION

Various stable or mobile barrier systems are currently used to contain flood waters. The best-known, most used and relatively effective solution for the retention of flood waters is the use of sand-filled bags. The disadvantage of this system is, in particular, that it requires a large amount of sand and many people to work to activate it, and after removing the barrier there is a problem of storing the sand charge, which is usually unusable for this purpose.

Similar problems, with the exception of reuse, arise in practice with many other types of flood barriers using various modular systems consisting of support columns and metal or plastic plates, with the disadvantage of their modular systems also their cost.

Quite often, a simple frame structure is used as a flood barrier element, forming a spatial geometric shape, provided with an impermeable fabric, often filled with various filler materials. The disadvantage of these solutions is, as in the previous solutions, the need for a relatively large amount of work in installing the flood control system in practice.

Recently, simple flood barriers filled with air or water have been used. These barriers are in particular in the form of long chambers or tubes and are usually made of a waterproof textile or plastic material with different systems of interconnection of individual segments.

Examples of such solutions are, for example, CZ pat. No. 291602, wherein the flood wall segment is formed by a water-filled bag which, when filled, assumes an arched shape above the base defined by at least one convex surface. In its apex region, the segment is provided with at least one filler neck and at least one venting neck, and in the heel region with at least one discharge neck. Opposite sections of the inner wall of the segment housing are connected in the cavity of the bag by at least one stabilizing partition. The sheath of the segment is made of a fabric with a double-sided application of elastomer mixture. In the end regions, the segment is provided with metal lugs for connecting to adjacent segments by means of connecting ropes.

Another example of such solutions is an air-filled flood barrier consisting of a single-chamber tube made of an airtight material, the individual segments of which are connected to each other by a system of connecting straps.

Also known is a single and dual-chamber system of simple flood barrier segments consisting of two-layer tubes made of flexible technical polypropylene fabric forming the outer layer and polyethylene foils forming the inner filling chamber, which are provided at their ends with filling openings which are closed by constricting them, and a special connector of a similar design must be used to connect adjacent tubes.

The essence of the technical solution

These drawbacks are largely overcome by the flood barrier element of the present invention, consisting of a single chamber tubular segment of waterproof material provided with a filling element, a venting valve, a connecting element, and a fastener, which is based on the tubular segment on its fronts.

Provided with a connecting element for connecting two adjacent tubular segments, and provided at least at one end of the tube with a firmly attached sleeve for overlapping the connection point of two adjacent tubular segments, the connecting element being a ring, preferably a so-called D-ring, firmly attached to a fixed safety carabiner is used to connect the rings of two adjacent tubular segments when the filling element is formed by a filling sleeve provided with a fire connection on its inlet side for easy filling of the tubular segment with water using conventional fire equipment, and the fastening element is a strip , fixedly attached at one end to the outer shell of the tubular segment and provided at the other end with an eye for connection to the terrain. The construction of the flood barrier element according to the present invention, in particular the construction of the connecting element with a safety carabiner connection, enables fast and safe connection of individual tubular segments of the forehead together and thus creating a flood barrier of the required length according to the extent of floods. After joining the tubular segments, the flood barrier is filled with water by means of a filling sleeve, wherein the sleeve for overlapping the joining point of two adjacent tubing segments, stretched and aligned on the adjacent tubing segment adheres to this segment and seals the joint of both adjacent tubing segments.

If necessary, it is also possible by placing the tubular segments on top of each other and circumferentially securing them to each other to form a flood barrier having a greater catch height than the basic height of the tubular segment.

BRIEF DESCRIPTION OF THE DRAWINGS

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows a front view of a flood barrier element, FIG. 2 is a plan view of a flood barrier element; and FIG. 3 then shows a side view of the flood barrier element. Execution example

The flood barrier element of FIG. 1 to FIG. 3 consists of a single-chamber tubular segment 1 of waterproof material, provided with a filling sleeve 6, a venting valve, a connecting element and a fastening element. The tubular segment I is provided on its front sides with a connecting element for connecting two adjacent tubular segments 1, which is formed to the front side of tubular segment I by a so-called D-ring 4, and to connect D-rings 4 of two adjacent tubular segments I fixed safety carabiner 5. Flood barrier tube segment I is provided with a rigidly attached sleeve 3 at one end of the tube to cover the connection point of adjacent tube segments 1. The filling sleeve 6 has a fire connection on its inlet side for easy filling of the tube segment I with water techniques. The fastening element is formed by a strip fixedly attached at one end to the outer shell of the tubular segment I and provided at the other end with an eye for eventually fixing the tubular segment 1 of the flood barrier to the ground.

The construction of the flood barrier element according to the present invention, in particular the use of rings 4 with a safety carabiner 5 connection, enables fast and safe connection of individual tubular segments 1 of the face to each other, thus creating a flood barrier of the required length according to flood extent. After joining the tubular segments I, the flood barrier is filled with water by means of a filling sleeve 6, the sleeve 3 pulled and aligned on the adjacent tubular segment 1 adheres to this segment and seals the joint of both adjacent tubular segments and the flood barrier.

If necessary, it is also possible by placing the tubular segments on top of one another and by circumferentially securing them to each other to form a flood barrier having a higher catch height. The barrier formed in this way can be further covered by a surface element covering the horizontal connection of the tubular segments L for increased safety

The flood barrier element can be used for direct separation of flood water from buildings and other property in flood areas thanks to the possibility of joining individual flood elements to any length according to actual needs and threats.
