Description

TECHNICAL AREA

The The invention relates to a dam-like protection device on the bank of a Waters against intermittent flooding.

STATE OF THE ART

It is known, according to the patent (Austria) AT 400 047 B , "Dam-like protective device", Int. Cl. E02B 3/04, (1995), which consists of an extendable shield disposed in a slot of the concrete base and held in the extended position by a bolt lock. As a drive to extend it uses a hydraulic cylinder or a self-locking rack and pinion combination.

The Deficiencies of this construction are due to the low stiffness of the Shield, of unreliability his tightly clamped Rand and caused by the complexity of the mechanism of its extension. The steel elements of the shield may under circumstances variable moistening quickly rust. Finally, the concrete base damage the landscape.

It is known, according to the German Utility Model DE 299 16 140 U1 "Wall for flood protection", Int. Cl. E02B 3/10, (2000), which consists of a wall, which is provided with sockets and fixed on the vertical side of the wall or sheet piling.

The Deficiencies of this structure is that for The assembly and disassembly of the wall requires complicated lifting mechanisms and big effort of the time. And, as above, the steel elements of the shield under circumstances of variable moistening the concrete wall will quickly rust and damage the landscape. These two facilities set a precise knowledge of the course of the water ahead and are thus at changed course conditions useless.

For Protection against floods is usually used the sandbags that are before the dangerous period on the riverside one lays around the residential buildings and others Protect objects. The lack of this way of protection exists in the watertightness of the sacks formed by Bank dam.

Other Way of protection from the floods closes the construction along the riverbank of a protective brick or brick wall of the concrete. The lack of this way of protection is that the outside of the area is spoiled.

It is known, according to the published patent application DE 10 2006 017 191.8 "Flood Protection System and Procedures for its Execution", Int. Cl. E02B 3/10, (2006), which consists of a series of skeletal elements, a support plate, a fabric width and sandbags. For secure hydro-insulation of the impact between the fabric widths of plastic films and the concrete support plate, this joint is filled with a sealer, for. B. with sound.

one Lack of this construction is that for preparation The support plate requires complicated lifting mechanisms and big effort of the time. In addition, one must Prepare support plate in advance. Second deficiency exists in need of the long push between support plate and Make fabric width watertight.

It is known, according to the published patent application DE 101 50 902 A1 "Mobile flood protection system", Int. Cl. E02B 3/10, (20061), which is spanned with at least one plate-like member that holds back the water, in which an element rests on the contact surfaces of at least two removable support structures, and the plate-like elements and the bottom joint of a filament.

It is known, according to the utility model (Austria) AT 006 490 U1 "Mobile flood protection element", Int. Cl. E026 3/10, (2002), that in sheet steel construction for the construction of dams has a bottom plate and a fold out of this protective wall, which is fixed in columns like columns, in particular a support wall in an inclined position relative to the bottom plate and is supplied with fabric widths.

Of the Lack of these two structures is that whole load is transferred from the water to the plate-like elements, what demands the great stamina. It pulls the great effort in materials, the complicated assembly and the great expenditure of time over it, which may not be the flooding can.

From the Internet are also the lightweight retaining walls "AquaFence (the address www.king5.com ) and "Water barrier" (the address www.flood-protection-system.com ), which consist of the set of supporting stands and the membrane and are set up manually. Their main deficiency of these retaining walls is that the burden of water rush is transferred to the membrane, and then to the stands. It limits the height of the supporting walls, forces the posts to be more dense and also strong, ie difficult to do, and very strong for the membrane strong substance to use.

TECHNICAL SOLUTION

The Invention, it has set itself the task of the time required for To reduce the construction of such facilities and at the same time Manually fill her. The task is done by means of wrapping the stacks of sandbags in the waterproof fabric width made of plastic films. The present invention leaves to, without pre-prepared base for the To get out of the dam. The earth's surface just has to be level and without Steiner and groundwater.

The invention is characterized in that the construction as a retaining wall against overfoaming of stacked sandbags 1 with waterproof fabric width 2 Made of plastic films that rest on a series of stands 3 hang during assembly and at the end of assembly, the sandbags are wrapped with fabric widths.

Of the Stand sets the metallic vertical bar with one or several struts before.

The installation is manually intended for installation. The height of the stands is approximately equal to 1,2-1,5 of the great of man. Statistics show that the majority of floods in Germany do not exceed the height of 2.0-2.5 meters. On the top of the stands there are the hooks 4 , and on the ends of the ropes 5 are the slings 6 made to hang on this hook. On these ropes you hang the fabric widths at the beginning of the assembly, to lay them later on the piles.

The horizontally arranged lower bent lower part 7 the watertight fabric width aligns under the stack with the sandbags. The vertically arranged middle part of the fabric width has its plane between stack and rope and protects the stack from the side of the river. Finally, she is thrown from the top of the pile to protect him from the rain and to fix his own position. For this purpose, the fabric width is temporarily hung on the rope, which is stretched between the stand. The rope is provided at ends with the loops which are on the hooks in the upper part of the uprights. The impact between the separated parts of the fabric width becomes sticky band like the side of the river 8th , as well as pasted from the inside.

The Special feature of the present inventive solution in that the burden of water rush is not on itself Stands take over, but whole load on handing over the pile of sandbags. The only Load on the stands is determined by the weight of the fabric width Field between the stands.

It allows to weaken the stands, they rarely set up and the demands to pinch them in the reason to reduce. This will be stand during the flood pressed to the pile and become the own form secure without deformation, then they can be used again be. Besides, such stands become quite be easy to do it manually without the help of lifting mechanisms can set up.

To the lower end of the metallic stand is a small metallic support plate 9 welded to provide the stable position of Sränders during installation of the system. All this simplifies the assembly and further disassembly and significantly reduces the duration of their implementation. The assembly and dismantling work must be carried out by the less qualified workforce.

The Procedure for filling the dam-like flood protection system consists of the following order of assembly.

To The signal "The threatening situation" are all elements erection (ropes, fabric width, sacks for the sand, the sand) become the place of assembly (for example, on the bank of the river).

• 1) die Installation der Stander, der Abstand zwischen der Ständer darf eine kleinen Abweichungen von der mittleren Bedeutung haben; Ständer dürfen die kleine Abweichung von der senkrechten Lage haben;
• 2) das Aufhängen der Seilen; auf jeder Ständer am Oberteil existieren die Haken, für die die Stücke der Seile angezogen werden; die Seilen dürfen den kleinen Durchhang haben;
• 3) die abgesonderten Stoffbreiten zerlegt man neben den Ständer.

After the rise of the water in the river the following works are done:

• 1) the installation of the stander, the distance between the stand may have a small deviations from the mean meaning; Stands may have the small deviation from the vertical position;
• 2) hanging the ropes; on each stand at the top there are hooks for which pieces of ropes are put; the ropes are allowed to have the small slack;
• 3) separate fabric widths are broken apart by a stand.

• 4) erfüllt man das Aufhängen der Stoffbreiten auf die Seilen,
• 5) erfüllt man die Verbindung der Stoffbreiten mit Hilfe von Klettband,
• 6) Der untere Teil der Stoffbreite auflegt man auf dem Grund zur Seite, die entgegengesetzt dem Fluss ist,
• 7) vorbereitet man die Säcke zur Auffüllung mit Sand.

After the growth of the threat of flooding

• 4) if you hang the fabric widths on the ropes,
• 5) one fulfills the connection of the fabric widths with the help of Velcro tape,
• 6) Lay the lower part of the fabric width on the ground to the side opposite to the river,
• 7) Prepare the sacks to fill with sand.

• 8) die Auffüllung der Säcke mit dem Sand,
• 9) das Legen der Sandsäcke in den Stapel auf die Stoffbreite annähernd dicht zur senkrechten Seite der Stoffbreite.

After overflowing as the flooding of the water the shore begins, the following is done:

• 8) replenishment of sacks with sand,
• 9) laying the sandbags in the stack on the fabric width approximately close to the vertical side of the fabric width.

• 10) wirft man die Stoffbreite von oben auf den Stapel von der Säcke und fixiert sie in dieser Lage.

When the level of water in the river reaches the maximum, that is, the full flood will happen

• 10) throw the fabric width from the top of the stack of sacks and fix them in this position.
