DIVIDING WALL IN OR AT WATER LICHAAH

5

The present invention relates to a system for forming a dividing wall in or near a body of water, such as a sheet pile wall, a wall of a pier or a port mouth, a jetty, an end barrier, etc.

Such partition walls are known in the art 2, wherein for instance use is made of sheet pile profiles. These are steel or metal profiles that engage each other and are sunk in a longitudinal direction into a substrate.

The known systems have a number of disadvantages. The known systems with, for example, sheet pile profiles have no or hardly any provisions for providing additional attributes. For example, it may be desirable to provide ground anchors to limit the depth to which such a dividing wall must be provided in a substrate. It may further be desirable to provide pads and to be able to raise the partition wall in the event of high water. All this is not possible with the known systems. Moreover, placing sheet pile profiles 25 has recently been greatly simplified and the necessary tools and machines are available for this. On the other hand, it is a disadvantage that such machines must be particularly strong, powerful and robust in order to sink the partitions into the substrate to a desired depth and required for their required robustness. A further disadvantage is that steel is a relatively expensive raw material, and the same applies to metal, when it comes to forming such partition walls, where particularly low costs are required, as well as a high degree of simplicity in processing. assemble or assemble thereof, in which respects the known systems therefore fall short.

It is an object of the present invention to address and at least alleviate the above-mentioned problems of the known art, for which purpose a system is provided which differs from the known art by the combination of measures according to claim 1.

Only at a distance which corresponds to the desired and possibly even adjustable length of the plank or plate-shaped wall parts, uprights need to be sunk into the subsurface, in contrast to the known technique, where adjacent uprights or sheet pile profiles 15 connect to each other and all have to be sunk into the substrate separately. As a result of the gripping means according to the invention, it is furthermore possible to mount or assemble the plank or plate-shaped wall parts in a simple manner, wherein the overall configuration of the system provides a considerable simplification in comparison with the known technique in all possible respects . Concrete elements can be used as plank or plate-shaped wall parts, which results in a cost saving compared to steel sheet pile profiles, which is considerable. Moreover, the engaging means can serve for engaging other additional components and elements, such as pads, ground anchors, etc.

The present invention has various preferred embodiments, which are defined in the dependent claims 2-21. These preferred embodiments will, within the scope of the present invention, as defined by the main claim No. 1, 1027473, be described below with reference to the accompanying drawings, in which the same or similar parts and components of the system are indicated by the same reference numbers, and in which: 1 shows a side view of a system according to the present invention;

FIG. 2 shows a partly broken away perspective view of a system according to the present invention in use; FIG. 3 shows a schematic and perspective view of an upright in a system according to the present invention and the method of assembly or assembly thereof;

FIG. 4 shows a sectional view of an alternative embodiment of an upright in a system 15 according to the present invention with respect to FIG. 3;

FIG. 5 shows a sectional view along the line V-V in FIG. 1; and

FIG. 6 and an alternative module according to the invention. with respect to that shown in FIG. 3.

Fig. 1 shows a system 1 according to the present invention. The system 1 comprises uprights 2, between which plank or plate-shaped wall parts 3 extend. The uprights 2 comprise engaging means designed as slots 4. The slots 4 serve for receiving therein the board or plate-shaped wall parts 3, which can be placed between the uprights 2 in the direction of arrows A with the ends thereof protruding into the slots 4.

It is noted that more slots 4 are provided in the uprights 2 than are necessary for receiving therein the end ends of the plank or plate-shaped wall parts 3. Thus, it is possible to insert into the slots 4 1027473 4 *. provide a fender 5 in the form of a gripping means.

Furthermore, it is shown in Fig. 2 that a slot 4 not used for a plank or plate-shaped wall part 3 can serve to mount a ground anchor 6 to the system. Such a ground anchor 6, as schematically shown here, can be arranged on the side opposite a water body 7 of the partition wall formed with the uprights 2 and the plank or plate-shaped wall parts 3.

It is further noted that slots 4 can be provided in other patterns around the circumference of the uprights 2. The design of the uprights thus obtained provides a high degree of freedom and is provided for effecting various forms of the partition wall , which consists of the uprights 2 and the plank or plate-shaped wall parts 3, but also when fitting additional components and attributes, such as the pads 5 and the ground anchors 6. Thus, the partition wall of uprights 2 and plank or plate-shaped wall parts 3 kinks 20 or even angles, etc.

With reference to Fig. 3, the structure of a possible embodiment of a post 2 in a system according to the present invention is further described. These comprise a core element designed as steel tube 8. The length thereof corresponds to the desired depth, over which the upright 2 is sunk into a base 9, and increased by the height that the upright 2 must protrude above it. It is noted that the tube 8 can also be made of a material other than metal, such as ceramics, plastic, etc. Furthermore, the tube 8 is here shown in a circular cross-section, but can also be rectangular, oval or hexagonal or the circumferential shape of have a pentagram. Naturally, this list is also not exhaustive.

1027473 # 5

The tube 8 is provided on its underside with a protrusion or flange 10, to which a head 11 of, for example, concrete or any other material is arranged. The flange 10 serves for a good attachment of the head 11 to the tube 8.

In a sunken state of the upright 2 in the base 9, on the head 11, which is arranged at the sunken end of the tube 8, module elements 12 are placed around the tube 8. For this purpose, the module elements 12 have a ( passage (not shown), which in the embodiment shown here is centrally positioned in the module elements 12. The module elements 12 have a continuous round surface and are themselves cylindrical. On the upper of the thus designed module elements 12 - the third in Figure 3 from below including the head 11, are placed module elements with a casing surface corresponding to the configuration with slots 4 therein intended for engaging the plate-shaped or plank-shaped wall parts 3. The module elements with engagement means designed in the outer surface 20 thereof as slots 4 are successively placed over the tube 8 in the direction of arrow B when assembling this upright 2. Thereby the tube is placed 8 inserted through a central passage 14 in the module element 13 and the module elements 13 can be successively placed on top of each other and around the tube 8. For a correct alignment of the engaging means, which here are designed as slots 4, each module element 13 is provided at a head end with a here-projected protuberance 15, while at the opposite end of the module element 13 a correspondingly shaped recess 16 is applied. These together form a means. When the module elements 13 are thus placed on top of each other around the tube 8, the protrusion 15 must fall into the recess 16, so that a correct alignment of the engagement means designed as slots 4 is achieved. For a good seal between the module elements 13, glue 17 can also be applied to the interface between module 5 elements 13. Such a glue is, for example, in the case that the module elements are made of concrete, concrete glue.

It is noted that a lower of the plank-shaped or plate-shaped wall parts 3 comes to rest on the upper surface 10 of an upper of the module elements 12, because no slot or other embodiment of the engaging means is realized herein, such as in the superimposed ones module elements 13. The upper of the module elements 12, which is still completely sunk into the substrate 9, 15 thus forms a support or stop for the lower of the plank or plate-shaped wall parts 3.

It is further noted that for sinking the tube 8 with at least the head 11 thereon, use can be made of a pump 18, which can be connected via a schematically designed conduit 19 to the interior of the tube 8 in order to arrow D to press liquid, such as water, through the tube 8 under pressure. The head 11 herein comprises at the lower end of the tube 8 a number of channels 20 along which the liquid or water can be ejected under pressure from the head 11 to process the substrate 9 in the immediate vicinity of the head 11 such that the tube 8 with at least the head 11 attached thereto and possibly also (concrete) module elements 12 into that substrate. It is thereby advantageous to have at least some of the module elements 12 already arranged around the tube 8, because the weight thereof, which presses on the head 11, is conducive to the galvanizing of the assembly thus formed.

1097473 7

Galvanizing the tube 8 with at least the head 11 thereon can be realized while or prior to the fitting of module elements 12, 13, but it is also possible to at least have all the module elements 12 wrapped around the tube 8 when an assembly thus formed is sunk.

If the module elements 13 are arranged around the tube 8 to a desired height, or in advance, rubber mats 21 can be placed in the gripping means 0 shaped as slots in the direction of arrow C. Such rubber mats 21 serve as sealing means between the module elements 13 and the plate-shaped or plank-shaped wall parts 3, when said plate-shaped or plank-shaped wall parts 3 are subsequently placed in the engagement means designed as slots 4 in the direction of arrow A.

It is noted that a plurality of ridge-shaped protrusions 15 can be provided and that they can also form part of a separate flat, or relatively thin, annular component that characterizes the small module. This 0 is also possible with the large module with a protrusion at the top. In this context it is mainly relevant that the engagement means designed as slots 4 are correctly aligned. This can also be realized in various other ways, as is shown, for example, in FIG. The central tube 8 'is oval in cross-section and the module element 13' around it falls in only one of two possible positions or orientations with respect to the central tube 8 '. The module elements 13 can also be formed in several ways, also on the outer surface thereof, for example with one, two, three or more than four slots or other engagement means and with a cross-section other than substantially round shape, such as oval, at least triangular, rectangular, etc. Furthermore, this figure 4 clearly shows that the slots 4 have the shape of a dovetail in cross-section. The engaging means can thus comprise a dovetail coupling when the head end of the plank or plate-shaped wall parts 3 are designed in a corresponding manner.

This allows the mutual cohesion between the various components of the system to be promoted.

It has already been stated that the combinations of recesses 16 and protrusions 15 together form alignment means. This also applies to the embodiment shown in Fig. 6, where a cylinder or sleeve-like collar 28 is also provided, with which alignment of modules relative to each other can be improved and which can be regarded as a coupling between the neighboring modules. The central passage 14 is thereby surrounded by the bush or oil-shaped collar 28. The collar 28 is thus per se a cylinder which extends partly in and partly outside the module element 13. If a correspondingly designed module element 13 is placed on the module element 13 shown in Fig. 6, that new module element 13 to be placed falls over the protruding part of the bush or cylindrical collar 28. Thus, a further improvement can be made. of the connection between module elements 13 mutually, in particular in a radial orientation, are improved by a longitudinally oriented bus or cylindrical collar 28 thus designed.

On the other hand, the combinations of protrusions 15 and recesses 16 are substantially radially oriented, but with that an improvement can be achieved with regard to the longitudinal alignment of, in particular, the slots 4.

With the bus or cylindrical collar 28, after assembling an upright, the central tube 8 can be withdrawn or left behind. The central passage 14 containing the bus 8 that has been released or can be filled with concrete or cement.

It is further noted that if use is made of a method, as described in connection with Fig. 3, for the galvanizing of the uprights 2, the hollow tube 8 can be filled after the galvanizing of such an upright 2 with cement or other filler to further promote the rigidity of the thus formed structure. Thus, during the sinking of the upright 2, the head 11 has the function of a nozzle that can be connected to a pressurized water source 18, but then loses that function if the hollow tube 8 is actually filled with cement. For this reason it may be advantageous to design the head 11, which thus only fulfills a very short-term function, as cheaply as possible and for that reason it can be extremely advantageous to form the head 11 from concrete.

It is further noted that, as shown in Fig. 3, the lower part of the plank or plate-shaped wall parts 3 is also at least partially sunk in the substrate 9.

This is favorable for obtaining a good seal. In this context it is noted that coupling means or seals can also be provided between the plank or plate-shaped wall parts 3 to increase the effectiveness of the partition wall to be formed therewith. For example, it is shown in Fig. 5 that the plank-like or plate-shaped wall parts 3 can be provided with one tongue 22 and a correspondingly shaped groove 23 at the mutually facing edges. 30 are provided to optimize the seal between the plank or plate-shaped wall parts 3.

Again with reference to Fig. 1, it is noted that a modular construction of the uprights 2 can still achieve a favorable function. The tubes 8 can thus be closed at the top with a removable closure piece, such as a cap 25 or bolder (not shown). Such a cap 25 can be removed in the direction of arrow E from the upper free end of a tube 8 which forms part of a post 2. Thereafter an extension piece 26 can be placed on the released end of the tube 8 in the direction of arrow F. Such an extension 26, a part of which is shown in Fig. 1, again comprises grooves 4 or slots in its outer surface 10, in which additional shelves 27 can be placed for raising the partition wall, if there is a need for it, as with high water. The board 27 is shown in dotted lines in Fig. 1 to make clear that this can be a temporary measure.

In the foregoing, the invention has been described in detail with reference to a limited number of specific embodiments, such as those shown in the accompanying drawings. However, the invention is by no means limited to those specific embodiments shown and described; the definitions according to the appended claims, in particular the independent claim, serve this purpose. However, after familiarizing with the specifically described and shown embodiments, many alternative and additional embodiments will occur to those skilled in the art, all of which should be considered within the scope of the invention defined by the claims, in particular the main claim. Thus, various alternative or additional placements or positions of engagement means, and even alternatives to the embodiment thereof as a groove 4 or slot, can be realized within the scope of the invention. In the connection of the neighboring module elements and the positioning thereof, sealing means and alignment means are used, designed as rubber mats, adhesive layers, assemblies of protrusions and recesses, and bushes or collars, etc. It goes without saying that alternatives for this be conceivable. For example, pin-hole couplings can be used as alignment means or, if the engagement means are designed as slots, the plank or plate-shaped wall parts can themselves function as the alignment means when a module element is rotatably arranged around a central tube.

Moreover, it has already been shown with reference to Fig. 4 that the design of such a central tube in conjunction with a passage therefor in the module elements can also be used as alignment means. Extensively a method has been described for allowing the uprights 2 to be galvanized with liquid under pressure. In an alternative embodiment, these can also be vibrated into the ground or driven into the ground, all of which should be considered within the scope of the invention according to the definition. of the appended claims.

In the foregoing, the invention has been described in connection with water separations. It is noted that, as is also defined in the main claim, the invention can also be used to form land divisions.

Examples thereof are fences, walls, etc. In the context of Fig. 3, it has been described above that use is made of a method for sinking the upright with modules, whether or not already attached thereto. Use was made of injecting moisture or water. It is also possible to develop a suction and pressing system as a supplement or as an alternative. A favorable possibility offered by the present invention is the reuse of modules when a system according to the invention is dismantled. Once a post has been sunk into a substrate, the central passage, whether or not in a tube 8, can be used for supplying cement or concrete to the immediate vicinity of the base of the post to create a larger concrete base by injecting the cement or concrete on site. This process can be concluded with the filling of the central passage or the tube 8. The canister or cylindrical collar 28 can be formed from plastic or also from cement, steel or the like. It is preferably an inert material that is completely insensitive to the effects of elements or influences from the immediate environment of the system according to the present invention. In unused gripping means, e.g. slots, elements other than the plank or plate-like wall parts can also be placed, such as pads or pads, in particular when use is made of a water partition against which a vessel must be able to moor. Example large and small module: fig. 7. The cams of the module serve for the alignment of the tO mutual module elements. These can be in conical, pyramid-shaped, semi-circular, triangular or trapezoidal shapes. The subsequent finding will be about the exact placement of the pillars and the suction into the soil via pin-tube guide.
