Definitions

  • the essence of the invention is that the hydraulic building element, according to the author's idea, realized as a universal, mobile, easy to built in, reinforced concrete structure made as mutually perpendicular parallelepiped formed segments integrally connected, so that their cross section has the appearance of latin letter "L" shape.
  • the hydraulic building element realized as a universal, mobile, easy to built in, reinforced concrete structure made as mutually perpendicular parallelepiped formed segments integrally connected, so that their cross section has the appearance of latin letter "L" shape.
  • a watertight barrier like on the existing facilities for passive defense against floods, so on the other places where previously there were no defensive lines.
  • the novelty of the invention is reflected in the fact that in the lateral sides of constructive elements, according to the invention, are realized longitudinal grooves in which, when setting up the block into security position, are inserted foamed rubber gaskets, which accomplished effectively sealing and protection from the breaking of water through the ensembles between adjacent elements and between base elements and the stand on which it is placed.
  • the novelty of the invention is also in that the subject constructive element has tubular openings for insertion of steel pins, by which are made necessary additional fixing to the foundation, preventing sliding and shearing or the elements connections one to each other.
  • the subject constructive element has tubular openings for insertion of steel pins, by which are made necessary additional fixing to the foundation, preventing sliding and shearing or the elements connections one to each other.
  • the advantage of the subject invention is represented with fact that the "L" shape shape elements are stored in the open. If are made well and properly, are inert to atmospheric influences, and in case of damage may be easily replaced.
  • the novelty of the invention is also represented by the fact that the storage of the elements in the line of defense is forming a new urban facilities which are giving to the stored elements a new active function.
  • the area where these new urban facilities are formed is enriched with new content and a new feature of stored elements is suitable for river banks and city quays.
  • the novelty of the invention is also the fact that the author has invented a series of technical solutions in linear storage of elements built in passive defense structures realized so that they always are at the scene of their application, and that there are unobservable.
  • Significant advantage is also, that the application of the invention does not disturb the existing aesthetic features of city quays and embankments.
  • the essence of the invention is reflected also in a series of constructive solutions of concentrated storing a number of elements close by the defense line or directly on the line of defense, whereby the storage solution completely customized to the terms of strict aesthetic requirements for coastal areas and significantly improve them aesthetically and make them more dignified.
  • the novelty of the invention is also the effective applicability of constructive, "L" shape elements for the quick formation of waterproof barriers also on the other flat surfaces such as asphalt roads, concrete plateaux, or on the previously prepared earth courts, and even on the under-prepared surfaces. This allows establishment of corrective mobile lines of defense on the roads, streets and other areas, when the need arises, and where formation of a defensive line was not previously been planned. In large floods, such are in most cases a second and third line of defense.
  • Defensive line formed by a series of dovetailed structural "L" shape elements is planned primarily as an additional protection from flooding by forming mobile line of defense on the city quays, dams in the cities and outside cities, but also successfully may be applied on the other vulnerable places where a stable defensive line are not formed, for making supervised embankments, embankments of second and third defensive line or as a corrective solution, and where the conditions of its application are satisfied.
  • Structural "L" shape element as it may be seen in Figure 4 , is realized as reinforced-concrete structure, the vertical cross section of which has the appearance of latin letter "L" shape.
  • the length of segment 2 of element is approximately twice the length of integrally realized, in relation to it, a perpendicular segment 3
  • Both segments 2 and 3 of the element 1 have the appearance of narrow rectangular cuboids and contain inside an appropriate reinforcing net 8. Free ends of this segment are flat vertical side edges 10 and 11.
  • groove 5 On the outer bottom side wall segment 3, in the line of vertical grooves on the sides, is the groove 5 for horizontal sealing which is made to prevent water leakage between the elements 1 and the base on which it is placed.
  • Groove 5 is straight in all its length and is also of a shallow circular cross section, and is used for insertion of foam rubber or of a similar sealing material.
  • parallel groove 6 which is a spare groove for additional sealing.
  • tubular openings 7 for the insert of pins 9 shown in Figures 8 and 9 perpendicularly to the surface are made tubular openings 7 for the insert of pins 9 shown in Figures 8 and 9 , which, in the process of defense activities are set only in the cases when the additional water pressure on the elements or the wave strikes by wind are arised, which may cause sliding and shear of elements.
  • Pins 9 are made of reinforced steel of a certain diameter and are integral parts of the equipment for a mobile defense. Their dimensions are determined to enter the lower ends in the openings on the base. Openings in the base may be prepared before or are made later when the elements are placed. On the inner surface of segment 2 slightly above the the gravity centers line of elements, are predetermined the spots for hooking and lifting of elements. It is possible to hitch the element in number of ways that differ according to whether the ring 12 is countersunk in the block or is free. Which hitching way will be applied depends on the storage system of "L" shape elements. Ring 12 may be positioned elsewhere also, which in turn depends on the storage of elements and is defined before an "L" shape element is made. When handling, element 1 is hitched in two positions. Superiority of each hitching position is in that is dimensioned in such a manner that it may receive the entire load of the element in case of need to be hooked on one position only. Lifting and moving of elements is performed by one of the available construction machinery.
  • Figures 32 and 33 shows two forms of gaskets - seals made of foam rubber for primary sealing. They are set at the time of installation in the specified grooves 4, 5 and 6.
  • "L" shape element 1 is positioned by its groove 5 on the horizontal gasket 26.
  • Vertical gasket 27 is positioned at the moment element 1 is aproaching to the him adjacent element 1.
  • "L" shape element is sufficiently heavy to effectively deform gaskets 26 and 27 and impress them into the ruggedness in the surface and thus achieve effective sealing.
  • Gaskets 26 and 27 have the form of tubes for horizontal sealing or double connected hose 27 for the vertical sealing. This form enable deformability and elasticity.
  • the Figure 34 shows the device and method of additional sealing.
  • the device consists of a plastic tube 28 which upper end exceeds into funnel 29, while the lower end is finnished by arch 30 bented at an angle approximately 30 degrees, which is realized in such a way that when the tube is in verticall position next to the wall, tube opening 28 will lean against the wall, respectivelly to the vertical side of the element 1
  • the length of tube 28 should be greater than the height of the wall.
  • sealing device When the leakage on a joint is observed, the sealing device is brought and set in a place of leak, and then into the tube 28 is poured a sealing material.
  • sealing materials usually are used a sand, gravel, earth, and the best is a clinker - ash.
  • Sealing material 31 sunk through the tube 28 to the leakage site.
  • water take it with and seal the leakage place. From the speed of water stream formed near the gap, depends the size of particles that the stream will carry with to seal the gap. So, first will be caught both, large and small particles, and on the gap will be stopped just large ones. Then, with the reduction of the speed of stream, on the gap opening will be deposited smaller and smaller particles as the gap does not close.
  • Static stability of the "L" shape element 1 are calculated to turnover, ie rotation the element around the edge of a small segment under the influence of the water force i.e moment made by this force to which resist the weight of element i.e the elements moment of stability.
  • the second condition for the element stability is the stability to shearing the element along the ground. Shearing of element along the ground is caused by the shearing force of water, and to it resists the friction force.
  • the friction force depends on the elements weight and of the coefficient of friction.
  • the weight of element 1 is determined and known, but the coefficient of friction is very changeable and as a factor of stability of a "L" shape element in the terms of flood defense, uncertain category.
  • the ratio of moments of the weight stability of the element and of turnover moment by water force is a stability coefficient to turnover.
  • the dimensions of the wall may be reduced, and thus its weight. This is important in the first place because of the manipulations with the elements when assembling and disassembling a wall, and then because of the cost of the elements. In the case lighter elements are used, in extreme conditions their additional loading by sacks is applied. Element is universal, but the dimensions are checked depending of the load to which will be displayed. If the elements are designed for a particular place, then the dimensions of the elements are determined according to the needs of that particular place.
  • elements must additionaly be secured against the shearing. Therefore, on the base are anticipated the openings through which steel pins are mounted to engage shear forces of the water and transferre them to the surface.
  • pins 9 it is possible, depending on the evaluation of ground foundation condition and of the water level, loading the element by sand sacks or by ranging sand sacks in raw besides elements additionaly to increase shearing strength. This is important in placing the "L" elements on the sodden earth ground foundation and the water level that is closer to the numeric level of stability limit to the shearing.
  • the figures 1 to 21 show the first of three described types of storage - linear storage.
  • element 1 Internal side of element 1 is forming passable foot-path 14 on the undefended quay wall, next to the edge beams 15 and slope of embankment 16 On the defended side of the quay wall 13 is formed the walking foot-path 17 which is not disruptive and is used as machinery circulation track during assembling the mobile defense line. By hooking up and raising, element 1 is placed in the defensive position on a flat surface of quay wall 13.

Defended slopes of the defensive dam 21 near the major rivers in our country are made of sand so the storage of elements 1 is easy. Drawing out the elements 1 is done with the mechanization moving on the crown 21 of the embankment and placing them in a defensive position. Around the "L" element 1 in the defensive position is compressed the removed earth 25.
  • FIG 22 shown is concentrated storage in the flake form storage space.
  • This storage represents the efficiency of the concentrated form of storage. It stores a large number of elements in a small space. In addition, it is by its form adapted to the possibillity that simultaneously, from each of the storage spur, can be independently taken the element and loaded on the transportation means.
  • the elements may be placed in the bottom level of the ground, partially buried in the ground or completely buried. Around the storage is manipulative way, and access to the storage should be from the more directions. Rapidity of taking the elements from storage depends on the needs, and accordingly is arranged the storage. traffic regulation. Rapidity of taking the elements is essential when there is a time shortness for the formation of mobile defense line.
  • the diameter of the circle of shown storage is 2R ⁇ 17.5 m, its area is about 240 m2 and stored is 250 elements. If the elements are of 2 m length, this correspond to 500 m of the defensive line.

  • Figure 24 is shown a concentrated multiple chambers linear two-rowed storage. It allows simultaneous downloading of elements from each of chambers.
  • the storage according to this example of invention can be realized with its bottom in the ground level, partially or completely interred.
  • This type of storage is suitable to be placed near the defensive line with a fences of enclosed public spaces or buildings, near by of some municipal buildings located near the banks of the river, and the space around them is finitely used to urban needs (for sewage systems suction pump stations -CS) or near the road used for downloading the elements. It is possible to place it in the dividing island between the roadway track that goes along with the defensive line, if around there do not exist other more suitable places.
  • Such storage according to the requirements of other relevant institutions, may be interred either partially or completely, which gives to it excellent storage facilities near the line of defense. Fast download of elements is important in case the time shortage available for the formation of mobile line of defense.

  • This type of storage represent a unique approach to organization of mobile defense against flood.
  • a defensive line for the defense against floods temporarily are given other functionality. They are used for formation of various architectural elements within the defense line zone or in the defense line. Because of the imperative that these elements are on the defense line, the adoption of this concept, revive the banks of rivers and encourages the development of contents that were previously developed in other places.
  • the pools are generally in open space, although not necessarily. There can be one or more pools. Number of elements causes a form of pool, and a form define usable area. Waterproofiness depends on the waterprofiness of the ground foundation. Upon termination of the needs, elements are removed, stored and area of the pool is returns the original application.

  • the embankments can easily be founded, also under the water.
  • the “L” elements have step-shaped cross-section and form a slope on the protected inclination of embankments according to the characteristics of basic materials, oscillations of the water, the size of waves and other local conditions. They are especially suitable for use in locations vulnerable by effects of waves.
  • the space formed by "L” element is filled with local material. If the filling materials are fine-grained and liable to leaching, the inner side has to be, before filling with material, coated by geotextile. This ensures filtrational stability of the structure.
  • the Figures 30 and 31 shows an example of cross-sectional assembly of the embankment, formed from the "L" elements. Often exists the need for the protection of banks from wave actions especially in the rivers and accumulation lakes or for the reconstruction of previously made, but damaged embankments.

Except using the "L" elements which are brought to the bank, the embankment can be made using local materials. Obtained are embankment structures, the static and filtration of which is very stable and resistant to the effects of waves caused by wind. The embankment structure is elastic and suitable for foundion under heavy conditions. The quickness for the embankment making is also significant. This gives to these embankments the expressive advantage over thr rigid stable objects.
  • the invention is suitable for the mass production. Its use is recommended in all places (urban and outside of cities) where there is necessary to achieve protection.
  • Mobile defense line is formed in a planned and prepared line for a mobile defense. Forming a defense line is implemented by the Service for the flood protection. Within the overall preparations, performed are the technical preparations and the preparation of performers. During the technical preparations accurately and even visibly are marked the previously defined lines of mobile defense. Then on the previously arranged foundation are placed the elements which form the mobile line of defense. The aim of such procedure is that during the first assembly, should be developed the most appropriate technology for making the mobile line of defense, to detect all the problems and to eliminate them, and to rehearse the teams and especially train the people who would later indenpendently manage the making of mobile defense lines.
  • the element is made as "L" profile, and therefore can be used and placed in the side within the embankment structures and in the supporting walls, where a protective height is something less than in the flood defense, but therefore the stability of the building is increased.
