Definitions
- Cellular Structure in particular a Retaining System or a Space-dividing Wall.
- the invention refers to a cellular structure, in particular a retaining wall or a space dividing wall, comprising a fore-part and a backfill which is connected to said fore-part by interlocking or friction.
- the fore-part comprises solid supporting units, preferably of trough- or box-like shape, arranged in the lateral and vertical direction in the front part of the structure.
- Such supporting units which generally are made of concrete, by the said arrangement establish a cellular structure of the fore-part and, thus, also of the backfill area being in connection with the inner side of the fore-part.
- Fore-part and backfill should be firmly connected to ensure stability against tilting due to the lateral earth pressures from the backfill. In the present context, therefore, considerations are concentrated to the compound function of fore-part and backfill.
- a task of the present invention to provide a cellular structure of enhanced connection stability.
- the solution to the task according to the invention is defined by the features of the claim 1.
- a well-defined position of the coupling units, normally made of concrete, relative to the corresponding supporting units is provided, particularly when compression of the filling material is applied.
- the spatial grid system formed by said anchoring units and coupling units is capable of housing large volumes of backfill, thus contributing to additional weight and internal friction for increasing overall stability of the wall against sliding and overturning.
- a preferred embodiment of the invention is characterized by a plurality of coupling units with a length extending into a compacted rear region of said backfill, and with corresponding anchoring units also being arranged within said backfill. The result is a remarkably enhanced stability of the structure even under difficult geological conditions.
- An essential variation of the invention is characterized by a plurality of said coupling units and/or a plurality of said anchoring units arranged one above the other without any vertical solid support therebetween other than backfill.
- At least one of said coupling units is at least partly made as an anchoring unit aranged in said backfill or connected with such anchoring unit in one piece.
- this entails a more complex design and production of such combined coupling and anchoring units when using a concrete technology, however, together with a further enhancement of the compound and shape stability of the structure as highly desired in some applications.
- back-filling and compacting during the construction becomes easier and more work efficient.
- Another essential and independent variation of the invention also refers to structures according to the preamble of the claim 1, but which is characterized by pairs of supporting units arranged in different elevations of the fore-part and positively secured against horizontal displacement relative to each other by locking means, in particular shear locking means, arranged in the backfill behind said fore-part and at a distance therefrom.
- locking means in particular shear locking means, arranged in the backfill behind said fore-part and at a distance therefrom.
- Fig.1 shows a vertical cross-section of a first embodiment of a cellular structure according the invention for slope retention, in a shortened illustration with only three tiers,
- Fig.2 shows again such a cross-sectional illustration of the foot section of a second embodiment of a cellular structure according to the invention, along the sectional plane marked II-II in Fig.3,
- Fig.3 shows a partial horizontal section of the cellular structure according to Fig.2, along the sectional plane marked III-i ⁇ there,
- Fig.4a to Fig.4d each shows one embodiment of a one-piece anchoring and coupling unit
- Fig.5 shows a vertical cross-section of a third embodiment of a cellular structure according to the invention, designed as a space dividing stand-alone wall.
- the front of the wall is made by a fore-part VB, which consists of box-like concrete supporting units TE arranged in tiers side by side and one above the other in a chessboard design.
- Each such supporting unit TE comprises a front wall Wl ascending with inclination towards the front and upwards, two laterally spaced side walls W2 and a bottom W3.
- the back of the supporting units is open and limited below by a rim VS projecting above and extending over the width of the box. Due to the chessboard arrangement on both sides of a supporting unit in one tier there is a gap L bridged by a supporting unit in the superimposed tier.
- the side edges of supporting units in one tier are arranged so as to overlap the side edges of a supporting unit in the tier below. Accordingly, each supporting unit rests on two supporting units in the tier below.
- the lowermost tier is secured against sliding in rest on a basis plane UG of sufficient supporting capacity.
- a shear lock provided, e.g. by means of an interlocking element FS engaging into the foundation.
- the fore-part alone has a comparatively small stability against turnover, and its upper regions are located before the natural sliding plane or friction angle. For this reason the overall stability of the structure is secured by means of an anchoring arrangement according to the invention.
- the latter comprises coupling units KE, which are stiff, in particular as a whole, or have stiff sections, and connected to the fore-part VB by interlocking or friction.
- the coupling units extend from the fore-part into the compacted or solid region in the depth of the backfill BF, at least in an essential part of the structure.
- connection between a coupling unit KE and a supporting unit TE is designed as an indent VZa, which can be closed preferably in vertical direction, thus facilitating the mounting under construction. Said indents are maintained in an interlocking closure by the backfill pressure from above, so as to secure the interlocking connection in an advantageously simple manner.
- beam-like anchoring units WDE with large- dimensioned profile surfaces exposed to the backfill pressure are provided for the connection between the coupling units and the rear regions of the backfill.
- the connection between the coupling and anchoring units is again accomplished by means of indents VZb to be closed preferably in vertical direction.
- the indent VZb is formed by an upwards open excavation at the coupling unit in combination with a downwards projecting section of the anchoring unit.
- the anchoring units are shaped as intermediate supporting units and interlockingly connected with neighbouring coupling units.
- the essential features comprise pairs of supporting units TE arranged in different tiers E2, E3 of the fore-part VB, where each of said pairs of supporting units are positively secured against horizontal displacement relative to each other by locking means, in particular shear locking means, arranged in the backfill behind the fore-part and at a distance therefrom.
- locking means are shaped as shear locking stop blocks SR being effective directly by means of indents VZb between anchoring units WDE and further indirectly through coupling units KE between pairs of supporting units TE.
- this example illustrates likewise a further independent variation featuring interconnecting means, in particular interlocking means SR, VBZ arranged in the backfill behind said fore-part VB and at a distance therefrom so as to transmit horizontal forces, in particular shear forces, from at least one anchoring unit and/or at least one coupling unit to at least one lower situated anchoring and/or coupling unit.
- interconnecting means in particular interlocking means SR, VBZ arranged in the backfill behind said fore-part VB and at a distance therefrom so as to transmit horizontal forces, in particular shear forces, from at least one anchoring unit and/or at least one coupling unit to at least one lower situated anchoring and/or coupling unit.
- Fig.4a shows a plate-like coupling unit KE in a perspective illustration.
- This coupling unit has a comparatively great width with elements carrying indents VZa and VZb.
- Such design is suitable in particular for difficult conditions which call for securing support units against torsion around a vertical axis.
- Fig.4b is a vertical view on a coupling unit KEW made as one piece with an especially heavy anchoring unit WDE having great profile surfaces, also for extreme applications.
- Figures 4c and 4d are showing multiple coupling units KEW, again made as one piece with heavy anchoring units WDE having great profile surfaces.
- two single coupling units KE arranged in parallel are provided here.
- Fig.4c supporting unit TE has two single coupling units KE, while according to Fig.4d the multiple coupling unit KEW by its single coupling units KE is connected with two neighbouring supporting units.
- single and multiple coupling units may be designed U-shaped, T-shaped, I-shaped or Z-shaped with regard to their arrangement within the depth of the backfill as well as with regard to their interlocking connection with a supporting unit or a plurality thereof.
- Fig.5 shows a cellular structure designed as space dividing wall RTM comprising two fore-parts VB1 and VB2 which are facing opposite to each other and have a backfill HF arranged therebetween.
- the coupling units KE provided here are connected with two supporting units TEl, TE2 of both fore-parts which serve also as anchoring units. Coupling units KE are extending through the backfill between both said fore-parts.
