Definitions

the invention relates to a support device for a retaining wall for supporting a slope and/or an embankment.
the support device comprises a foot section, the foot section being designed as a foundation plate.
Retaining walls also known as retaining walls, are used to secure slopes, embankments and/or cuts. Retaining walls are used, for example, to secure traffic routes, with stability taking precedence over aesthetic aspects. Furthermore, retaining walls are used in landscaping and horticulture, with natural stone and/or granite preferably being used for integration and incorporation into the landscape. The cost of such natural stone steles is very high compared to concrete. So far, up to 30% of the natural stone pillars have been sunk into the ground, which entailed considerable financial expenditure. In addition to the economic aspect, natural stone steles are very heavy, with 30% of the weight to be handled being due to the anchoring or sinking.
the pamphlet JP-H11131504A describes an L-shaped retaining wall with an integrated floor, and a method of constructing the retaining wall.
the natural stone used herein is L-shaped, which has a foot portion (shank) which is sunk into the ground. Both the exposed portion of the stone and the buried portion are formed from the natural stone, resulting in a very heavy weight and a very high price.

the retaining wall 12 including the support device 1 and the natural stone stele 8 is and/or is filled with earth material 17 on the earth side 5 , which forms the slope 13 .
the supporting device 1 and in particular the natural stone pillar 8 is slightly heaped with a layer of earth 18, this layer of earth having a heaping height h ⁇ 10 cm.
figure 3 shows a further embodiment of a support device 1, wherein the support device consists essentially of the support device 1 figure 2 is equivalent to.
This embodiment is arranged on a foundation 14 in the form of a thin layer of concrete, for example with a layer thickness of 1 to 10 centimeters.
the concrete layer serves, for example, to improve stability.
the attachment interface 10 and counter-attachment interface 9 are designed as internally threaded anchors 19 and screws 20 .
the internal thread anchor 19 is designed similar to a dowel and is designed, for example, as a hollow cylinder with an internal thread, which has an expanding or wedging section at one end for positive connection in a hole or blind hole of the stone stele 8 .
the internally threaded anchor 19 is inserted into the hole of the stone stele 8.
the screw 20 has an external thread and is passed through a passage 21 of the holding section 2 from the earth side in the direction of the air side. the Screw 20 is screwed to the internally threaded anchor 19 and thus holds the stone stele 8 firmly connected to the support device 1.
figure 4 shows two supporting devices 1 in a plan view from above.
the support devices 1 are arranged adjacent and at an angle to each other to form a corner area 22.
the foot sections 3 are tapered with a taper 23 towards the ground side 5.
the taper 23 is designed as a trapezium, in particular an isosceles trapezium.
FIG 5 shows a further exemplary embodiment of a support device 1.
the support device 1 is made in particular from a foamed plastic.
the support device 1 comprises the holding section 2 and the foot section 3.
the holding section 2 and the foot section 3 are of essentially flat design and in particular have recesses.
the holding section 2 is designed, for example, as a rectangular area and/or has a rectangular contour.
the foot section 3 is in particular designed in the shape of a trapezium, with the trapezium tapering from the air side 6 to the ground side 5 .
Holding section 2 and foot section 3 are arranged in particular at right angles to one another.
a support section 24 connects the holding section 2 and the foot section 3.
the support section 24 comprises two support section sides 25a, 25b.
the support section sides 25a, 25b define, in particular together with planes defined by the foot section 3 and the holding section 2, a tetrahedron.
the support section 24, in particular the support section sides 25a, 25b forms a V-shaped indentation and/or fold.
the support section sides 25a, b form a housing, in particular as a protection for underlying and/or accommodated electronic components against earth material, moisture and other mechanical, chemical and/or biological environmental influences.
there is and/or will be a Arranged pump for pumping water and/or using the attached stone stalks as a fountain element.
an abutting portion of the two support portion sides 25a, 25b is rounded.
the foot section 3 has a coupling interface 16 and a negative feedback interface 26 .
the holding portion 2 also includes a coupling interface 16 and a negative feedback interface 26.
the coupling interface 16 and negative feedback interface 26 are arranged on different sides, for example left and right, in a width direction.
the coupling interfaces 16 of foot section 3 and holding section 2 are arranged on the same side.
the coupling interface 16 is designed for coupling and/or latching with the counter-coupling interface 26, for example as a joint-like connection.
the holding section 2 has a holding section recess 28 and two lead-through recesses 27 for stacking a plurality of the support devices 1 .
the foot section 3 has a foot section recess 29 .
Foot section recess 29 and holding section recess 28 are, in particular, V-shaped and/or congruent to the correction of support section 24.
Feedthrough recess 27 is essentially rectangular, with the corners being able to be rounded.
the feed-through recesses 27 are used to feed through support sections 4 in the stacked state.
depressions 30 are arranged on an upper side of the foot section 3 .
the indentations 30 are arranged in particular in such a way or are congruent with nubs 32 in a top view from above, so that nubs 32 arranged on the bottom side 31 of the foot section 3 be included.
the nubs 32 are conical, for example. When stacked, the nubs 32 engage with the indentations 30.
the fastening interfaces 10 for fastening and stabilizing the stone stele are arranged in an upper half of the holding section 27 .
the fastening interfaces 10 are in the form of openings and/or holes.
screw connections and/or pins are guided through the attachment interfaces 10, which are countered and/or screwed on the ground side.
the other end of the screw connection and/or pin is in particular coupled and/or connected to the stone stele. Due to the arrangement in the upper half, a particularly good stabilization of the stone stele is possible.
figure 6 shows the embodiment figure 5 in a plan view of the holding section 2, in particular the air side of the holding section 2.
the knobs 32 and recesses 27, 28, 29 are shown.
figure 7 shows a plurality of support devices 1, in particular according to the embodiment of FIG figures 5 , wherein the supporting devices 1 are arranged in a stacked state on a pallet 33.
