Description

Structure of the element assembly of mobile modular flood barriers

Technical Field of the Invention

The invention relates to a structure of the element assembly of mobile modular flood barriers for the easy, fast, effective, and efficient assembly of a comprehensive module set or the combination of some components with compact panels of the desired shape, design, and material concept from various manufacturers in general. The invention falls within the water industry.

Background to the Invention

From the state of technology, fixed and portable flood barriers are known, from which flood walls are assembled . They are various types of walls anchored to fixed or removable support columns and various types of barriers filled with water or another substance.

Water-filled bags with a triangular cross-section placed on the base are particularly known. Compliance with the cross-sectional shape can be ensured using a supporting rod structure or compartments deployed inside the bag. The bag's coating is made of polyethylene. These barriers take up very large storage space.

Flexible plastic bags with a tube shape are also known . These are filled with water and their advantage is the high ability to adapt to terrain. The disadvantage is that they cannot be used for a higher water column, they are not sufficiently stable with flowing water, and the plastic might be pierced by a sharp material.

Another known system is the system of open bags with a trapezoidal cross-section, consisting of a massive tubular steel frame and geotextile shell, possibly coated with plastic. They are filled with sand, soil, or water. A flood wall segment based on water-filled bags, described in the published WO 02/10519 PCT application also has a similar structure. The common disadvantage of these structures is their low resistance to tension in the cross-sectional peaks. For their fixation they require a supporting construction.

Another known flood barrier system is based on the construction of free-standing columns and transversal fillings. The disadvantage of this system is the necessary anchoring of column spurs using a massive structure.

Another known flood barrier system consists in a set of bearing elements obliquely and firmly anchored in the ground with a defined spacing. Such an adjusted line of oblique bearing elements is coated and possibly fixated with sand-filled bags.

The next one is a system of vertically and horizontally connected modules, fixed to each other with spurs. The disadvantage of these systems is the necessity of their solid anchoring to the ground , making the barrier assembly and disassembly more difficult. Another known system is the system of a lightweight flood barrier structure formed by a set of oblique modules, supported from behind by a set of horizontal and oblique spurs, which are again firmly anchored in the ground , as well as a system of modular flood barrier construction with a vertical of oblique wall, where it is counted on the flooding of horizontal plates and spurs as it is described in the SK 5847 utility model. A certain imperfection of this system is the vertical diversion of wall modules due to local terrain unevenness under the horizontal plates. This system does not allow the essential plane curving of the modular wall. Also, during the flood barrier's operation , it is not possible to push the wall modules to the original position under the water pressure acting on the barrier walls due to the decline of spurs sunken in the waterlogged ground .

The limited options for flood barriers in terms of their mobility, also affected by their solid anchoring in concrete and non-rigid substances, as well as the disadvantages resulting from the limited copying of uneven ground, having created space for the development of such a structure of mobile modular flood barriers that would be manufactured in the form of a kit with a minimum number of various elements, mobile without solid anchoring components, easily portable, mountable, detachable, and storable, as well as usable for both solid and loose subsoil, the fixation of its position ensured by hydrostatic water pressure forces, also stable with a higher water column, allowing to copy the ground both in terms of high space, manufactured from waste material, such as plastic, which is inexpensive and minimally sensitive to weather influences, in order to allow correction of wall stretching, even under the hydrostatic water pressure load.

The result of this effort is the structure of the element assembly of mobile modular flood barriers described below in this invention , marketed as a package - a set of specified elements for the application to retaining panel modules by various producers, or a specific comprehensive set of supportive elements along with retaining panel modules.

Summary of the Invention

The above deficiencies are removed with a structure of the element assembly of mobile modular flood barriers according to this invention, consisting in the advantage that its essential parts are made from plastic waste and other appropriate materials, such as wood and metal or their combinations, as well as other things such as composites. The submitted invention allows the creation of two different configurations from one set system. The first configuration is a disassembled structure of the element assembly of mobile modular flood barriers delivered to the customer from the supplier or manufacturer in a specified form or as at least three types of structural mobile modular flood barrier elements selected by the customer. Usually it would be a structure of the element assembly of mobile modular flood barriers without retaining wall modules or segments. These could also be by other manufacturers. Through the assembly and mounting of the first configuration set's structural elements and their application to the retaining wall modules or segments, a flood mobile modular barrier is created. The second configuration is a disassembled structure of the element assembly of mobile modular flood barriers delivered to the customer from the supplier or manufacturer in a comprehensive form of the essential mobile modular flood barrier elements, including the retaining wall modules or segments. Through the assembly and mounting of the second configuration set's structural elements, a flood mobile modular barrier is created .

The structure of the element assembly of mobile modular flood barriers thus consists of supportive spurs adjustable under load, oblique retaining wall modules, pressure valves, connecting rods with a spherical bond or a bond allowing partial spherical movement, bases, side wall-connecting elements, corner-coupling elements, flexible transition elements, solid supportive spurs, and retaining caps. The supportive spur element adjustable under load has a rod-like shape and consists of a central rotating part, a lower solid part with an adjustable tip connected to the central part's lower end, and an upper solid part fitted with a gripping cap at the central part's upper end , or fitting into the gripping cap. The adjustable telescopic tip is set according to the terrain quality. By turning one part of the spur element, such as the central part, it is possible to change its length and pre-tension even under load . However, there are also other options of turning some part of the spur element in order to change its length. The upper end of the central part is fitted with a retaining cap. The supportive spur element is inserted into the base with a shaped groove, which ensures even in the case of inaccurate insertion that due to the operational load the spur element will establish itself in a stable position. The pressure valve consists of an anchoring part and pressure part, with the pressure valve's anchoring part tiltably placed to the pressure part. It is also advantageous if the pressure valve's pressure part is fitted with a set of prongs and teeth on the lower edge. The pressure valve increases the flood protection system's stability. It also ensures mechanical anchoring in cases when the front edge sinks into the ground due to operational load. The openings in the valve can be used as mechanical anchoring using pins or other anchoring elements. The valve's physical philosophy is based on the fact that in the area with high hydrostatic forces, only a small area is sufficient to draw a relatively high stabilization force. Under certain conditions and based on the user's choice, the mobile modular flood barriers can also be used without the pressure valve. The angle of the oblique retaining wall modules can vary between 35° and 60°. The connecting rod with spherical bond is fitted with spherical pivots at its ends. In case of need, it is also possible to change their length by turning the central part. The connecting rod's spherical bond with a retaining wall module and a base provides the option of sufficient system adjustment to the terrain conditions. The base has three-point anchoring and is fitted with rubber pads, silent-blocks. In case of ground unevenness or instability, they are able to adapt to it with their rotation. On an adhesive surface the rubber ensures sufficient adhesion . In case of a soft surface, the silent-blocks are pressed into the ground , creating a shape bond and increasing the entire system's stability and versatility. In a preferred embodiment, the base can have an additional anchoring hole. The side connecting wall element can be produced in several types. For example, it has the shape of a moulding with a longitudinal shaped groove and an adjacent connecting wall moulding with a complementary longitudinal groove. In a different alternative, there is the side connecting wall element and an adjacent connecting wall moulding with a longitudinal shaped groove, into which the connecting bar shaped as two complementary grooves interlocks, for example with a cross-shape as number eight. In the basic barrier design, this eight-shaped establishment provides adequate flexibility, firmness, and easy system assembly. The bars can also be appropriately d ivided. This assembly method has the advantage that the bars can be inserted from above and the retaining wall modules and blocks do not have to be moved to a large extent. If the connection profile is a part of wall blocks, the so-called male - female, the entire retaining wall modules and blocks have to be handled and inserted downwards. In case of clip joints, sideway insertion is possible. An alternative where only the male is part of the block and the connecting element is a double-sided female, functions similarly as the current basic alternative. The connecting elements can be a fixed block part or mounted to them using various permanent or detachable joints, such as riveting, screwing , gluing, welding, etc. The system in the basic wall block alternative to which connecting elements are mounted has the advantage that it can also by fitted on wall blocks by other manufacturers, made of another material, or having a different but suitable shape. There are also other types of connections. Fixed corner-coupling elements of the desired shape and size can also be installed into the wall module set. A fixed corner connecting piece has a trapezoidal or triangular shape and fitted with handles on the sides. It is also possible to use a corner piece with adjusted valves, where one valve remains while and the other one is nicked. The valve is inserted below the other one. The valves are relatively flexible, bending under the load and adjusting to the terrain . The flexible transition component consists of at least two solid trapezoidal or triangular segments with handles on the junctions and sides, allowing significant changes to the entire flood wall's shape. It is possible to pivot the adjacent retaining wall block sets in a large angular range during usage. The number of segments can be two and more; it is the so-called roll-up system. The entire mobile modular flood barrier system can be functionally and structurally reduced based on the requirements and operational conditions if possible. This is possible at the expense of reducing functionality and flexibility, which however may not be necessary for the specific application . An example is the option of replacing the bases and rods with a simple solid structure, firm enough and ensuring sufficient functionality. Such structural elements may have varying shape and dimensions, as well as made of various semi-products. The options are, for example, production from bent or welded sheet metal, standard profiles, such as U, Jokl, I , L, etc. In this simplified example it is made of the U profile and instead of a flexible and uniform change to the length of the spur bars, the solid supporting spur elements are mechanically locked in a preset position. The solid supporting spur element is adjusted to anchoring on both ends. The retaining cap has a spherical or cylindrical pin and it is used to anchor the connecting rods to the base, retaining wall modules or segments, and to connect the supportive spur elements adjustable under load to the retaining wall modules or segments. The oblique retaining wall module consists of at least one segment and it is a full or lightweight structure. In one alternative the oblique retaining wall module is fitted with fixed side wall connecting elements on the sides. The oblique retaining wall modules can be made of materials such as metal, plastic, wood , glued and pressed compositions, and rubber. The shape of the front plate, which in the basic version is made of plastic and ribbed , can be otherwise modified. A set of at least five components and supportive spur elements adjustable under load or solid supportive spur elements, oblique retaining wall modules, pressure valves, connecting roads with a spherical bond, bases, side connecting wall elements, solid corner- coupling elements or flexible transitional elements, and retaining claps in assembled state, forms a mobile modular flood barrier.

The advantages of the structure of the element assembly of mobile modular flood barriers according to this invention are apparent from its effects manifested on the outside. This invention's effects consist mainly in the fact that the proposed design meets the condition to minimize the price of barriers manufactured under standard workplace conditions, while maintaining the desired functionality in the simplest design possible. The concept is suitable without any structural modifications for all terrain types, such as soft, semi-hard, and hard surface. This versatility is ensured by a positional tip, which is the most extended in soft ground , partially in dense, and fully retracted in hard ground. In hard ground , friction is ensured by three rubber silent- blocks. The barrier's height can also be adjusted under water load , providing solutions in critical situations and facilitating the assembly. If the same kit pieces are used, it is possible to stop floods with a water level of 0.4m to 1 .8m. The length of spacing bars can be adjusted under load as well, providing solutions in critical situations in the terrain . The manufactured plastic blocks do not need to be modified; the only adjustment is the drilled holes for screws (if the connecting elements are going to be glued to the blocks, their number is reduced or they are completely removed). The anchoring elements are flexible and adjust to the terrain slope and elevation unevenness by pivoting. The structure also enables the elimination of elevation unevenness, such as reasonably large pits, hills, and potholes. The system can also be installed for sudden changes, such as curbs in urban areas. When storing disassembled parts, the blocks can be stored on top of each other without problems. The connecting rods are placed above the zero ground line, in order not to collide with the surface. The metallic components can have a suitable surface finish with paint or metal coating, such as zinc coating. The module retaining the spacing bars in the plastic in the basic version transfers the force to the outer area of doubled ribs, favourable in terms of block firmness. In case of ground unevenness, the eight-shaped connection ensures an option of the entire assembly unit's partial rotation in relation to the adjacent units, thereby ensuring the overall flexibility. When applying corner components, whether solid or flexible, it is possible to significantly shape the entire flood wall convexly or concavely. By applying the sealing cuffs, the systems' closeness was significantly improved. The design is simple and easy to assemble also for less skilled personnel. To optimize the design and simplify the unit's kit structure for less demanding operational conditions, several modification options were designed for the connecting module production. In some alternatives it was possible to exclude the vertical connecting bars from the design while maintaining the unit's original functionality. To save on material, the possible savings in the block production with a modified rib shape was processed and simulated. The original block weight was 24kg; after the modification, the block was 20kg at a comparable result as the FEM finite element method results under the operational load. As a problem in the design, we see the relatively high expenses when making new forms for the mass production of blocks or connecting parts. The extrusion technology appears to be the optimum connecting module production from plastic. In the basic design, it is possible to stop a flood level up to 0.8m, .1 .3m, and 1 .6, using the same kit pieces. The good storability of disassembled plastic blocks is conditioned by the fact that no other object or its part protrudes from the block's basic packaging . A partial adjustment to the block's angle in relation to the terrain is possible in the sheet metal's bottom U profile. The U profile's corner sinks into the soft terrain and stabilizes the system .

The telescopic tip 1_2 adjusts to the terrain quality. By rotating the central part H of the supportive spurt element 1 it is possible to change its length and pre-tension even under load.
