Abstract

Flood barrier consisting of modules being placed one over one in horizontal arrays. The barrier is formed of prestressed modules (4) having chamber structure and being manufactured of corrosion resistant material. Each module (4) is composed of thin walled sections (1) being strengthened using their shaping, that the sections (1) are bound together and they form safety buffer. Modules (4) forming barrier are mutually arranged in vertical direction. The modules (4) are also sealed using self locking joins (2). Self locking joins (2) are placed in alternating mode among single horizontal barrier arrays forming long distance unlimited barrier. Barriers are anchored to the surrounding surface using stabilising support (3) and being placed in hinged mounting beneficially.

Description

Flood barrier Field of technology The invention concerns the flood barriers, which form setting up system restraining the water penetration into buildings and protected territory. The solution concerns the areas of constructions or equipments contributing to the protection of rivers and coasts.

Present state of technology

According up to this time state of technique many solutions of flood barriers or other type water barriers is known.

Wholly different arte equipments characterised by the application of bags filled with flood water and consequently not connected with the solution included in this applications of invention.

Further, the solutions realised according the invention US 5645373, in which elastic modules based on plates conception and having unchangeable height are given. Modules are constructed on transit tubular arrangement. The impossibility to increase the height of barrier according the requirement represents certain disadvantage.

Other known solution is given by the US invention 6443655, in which each module has three anchored supporting columns complementing each other. Intrinsic modules are of plate conception and are not strengthened by application of shaping. Modules do not link up, as well.

Other known solution according the patent DE3448322 detects protection sections in its being situated among supporting columns and being anchored to the foundations. Own modules are not reinforced shapely, prestressed and interconnected horizontally alternately, as well.

According the US6012872 invention flood barriers consist of containers, omega sections or vertically cut tubular sections. However, mentioned solution does not include horizontally alternately interconnected modules, which would be reinforced by shaping and prestressed and together bound simultaneously.

The invention DEI 9807141 presents another solution, in which modules are constructed under application of shape strengthening with distributed stress state. Quite different solution of protection wall including its construction is a matter of this invention.

Characteristic of the invention

The flood barrier according designed solution consists of modules being pilled up one over one in horizontal array.

The principle of invention consists of a solution suggesting that the barrier is formed of prestressed modules having a chamber structure and are manufactured of corrosion resistant materials. Each module is composed of thin walled profiles which are strengthened by use of shaping. The sections are so interconnected and form safety buffer. Modules being assembled in the barrier are vertically arranged and sealed up mutually. The barriers are anchored due to an application of stabilising support to the surrounding surface. Anchoring of a barrier to the surrounding surface using the hinged mounting of stabilising supports represents a very beneficial solution. Modules are horizontally arranged and sealed mutually by means of self-locking support. Connections are located intermittently among horizontal barrier arrays and form long-distance unlimited barriers. Barrier structure flexibility and its impact resistance represent an advantage of solution according to the invention. Further advantage is unit construction system, simple and speedy assembly of standard elements without application mechanisation means. The achieved variability of stabilising supports being hinged mounting and stabilised make possible a levelling process of potential barrier inclination.

List of the figures in the drawings

Realisation example of designed solution is given in reference to the drawings in which in

Fig.l prestressed module composed of profiles is illustrated.

In Fig. 2 is situated the self locking joint situated among modules.

In Fig. 3 is presented the hinged seating of stabilising support in partial detail illustration

In Fig 4 is given the variant of barrier realisation without application of self-locking joint

Examples of the invention

Before flood barrier installation according invention it is first necessary the elements to build- in definitively. Those ones are ending columns for anchoring of extreme flood barrier module 4,, anchoring slots and anchoring elements (could be channel and/or trough) for hinged seating of stabilisation support 3.

Example 1

According designed solution the flood barrier was produced consisting of prestressed modules 4 being pilled up one over one in five arrays as could be seen in Fig.3. The barrier is in distance edges anchored in ending columns. Prestressed modules 4 are manufactured of corrosion resistant steel. Each module 4 is composed of three thin-walled sections l_(see Fig.l). Strength of module 4 is increased due to thin walled section l_shaping. Simultaneously, the sections 1 are so shaped that modules 4 could be bound together by vertical barrier assembly. In horizontal direction, the modules 4 are sealed together by application of self locking joints 2. To attain the increased barrier strength, the self locking joints are not placed one over one in single horizontal module arrays, however they are distributed in single arrays using alternating mode. Flood barriers are anchored by application of stabilising support 3 to the terrain surface. Barriers are bound in hinged arrangement to the terrain using anchoring slot or channel, see Fig.3. Barriers are bound to the stabilising support 3 by means of clips.

Example 2

According the designed solution flood barrier was manufactured consisting of prestressed modules 4_. For sealing, the self locking joins_2 were not applied but the modules were only built up in vertical direction in arrays one over one and anchored among the stabilising supports 3. Stabilising support were strongly anchored to the environmental terrain. In this case these are bolted on. Example 3

In a further variant workmanship, the modules 4 were manufactured as in example 1 and afterwards the modules were bound in horizontal direction and sealed using rubber or another formable sealing material and or by application of hydraulic or pneumatic method. Barriers are anchored by means of stabilising supports 3 being set into concrete in surrounding terrain or bolted on, anchored on "bayonet", by means of locking mechanism. Barriers could be manufactured with benefit of stainless material but could be also manufactured of structural steel using subsequent surface coating. Another type of acceptable materials for barrier manufacture are s c water resistant materials.

Industrial utilisation

Practical application of designed solution is possible as barrier against floods at places of expected backwater.
