Definitions

  • the invention relates to a gabion basket as an element of a noise protection device.
  • Gabions or gabion baskets are used, for example, but not exclusively, in landscape architecture to build walls.
  • the most common uses are privacy screens, embankment fortifications or retaining walls.
  • Gabions are used as support elements on slopes to absorb the earth pressure. They can be used as an alternative to precast concrete or concrete and stone walls. Due to the excellent properties of sound absorption, gabion walls are also designed as noise protection systems.
  • Gabions are often used in front of residential areas along busy roads or railway systems, whereby they are stacked to form noise protection walls and connected to one another if necessary. Covered with topsoil, green walls are created in this way and contribute to the maintenance of biodiversity.
  • EP 3 214 224 B1 discloses and describes a gabion basket, a noise barrier consisting of the gabion baskets and a method for moving the gabion baskets.
  • the gabion includes an essentially cuboid cage.
  • the cage has a bottom, two front walls located on two opposite lateral sides of the cage, and two side walls located on both lateral sides of the cage.
  • the bottom, the front walls and the side walls consist of grids that are fastened to one another.
  • Two partition walls are arranged in the interior of the cage in such a way that these partition walls are firmly connected to each side wall delimiting the gabion basket inside the cage.
  • the internal volume of the cage is thus divided into two front compartments and an intermediate space formed between the two partitions.
  • the front compartments are each filled with a filler - a granulate - which does not pass through the meshes of the respective floors, front walls and side walls or through the partitions.
  • the filler is thus kept entirely inside the front compartments.
  • the gap is able to accommodate granular material suitable for soundproofing.
  • the granules of the soundproofing material are let through the delimiting surfaces in such a way that the soundproofing material can spread freely within the intermediate compartment on both sides of the partition.
  • U.S. 2004/0123531 A1 describes a barrier to protect against shock waves.
  • Shock waves are to be understood here as sound waves and/or air movements.
  • the barrier itself is made up of a combination of soil containing and reinforcing structures stacked one on top of the other such that these structures form two vertical walls.
  • the means for absorbing the shock waves are placed in the space between the two walls.
  • the protective barrier also comprises cross-connection means engaged with the vertical walls in order to increase the compactness of the protective barrier, the barrier being suitable for protection against said shock waves - essentially sound waves.
  • the protective barrier has properties for damping and absorbing the sound waves.
  • the structure of the entire barrier can consist of a main structure of substantially pyramidal or rectangular shape, having two end walls, transverse vertical connection means and horizontal connection means, and a cover.
  • the noise protection wall consists of individual rectangular wire mesh baskets, which in turn are composed of hinged longitudinal and transverse walls.
  • the transverse walls are provided with hooks assigned to the horizontal bars and have vertical bars protruding over the lower horizontal bar, so that they can be plugged into one another or onto one another or onto corresponding support elements.
  • the longitudinal walls which form an outward-facing bulge or arch after being hooked into the transverse walls, are then connected to the transverse walls, which are already erected and stabilized here, by bending the hooks.
  • a stiffening element connecting two transverse walls is used for stabilization, usually in the form of an L-profile, which is arranged with the angle pointing upwards so that the soil cannot become stuck.
  • This single, stable wire mesh basket is connected to other corresponding wire mesh baskets, in which the transverse walls are placed on top of each other or plugged in, resulting in a very stable overall structure into which the soil can be filled afterwards.
  • the object of the invention is to overcome the obvious disadvantages of the prior art and in particular to provide a gabion basket as a noise protection element which meets the approval-related requirements for a long service life.
  • a gabion basket has at least two separate areas as a noise protection element, each of which extends over the entire height and the entire width of the gabion basket.
  • the areas, or sub-segments, of the gabion basket are delimited by at least one separating device.
  • There are two sides to the gabion basket - one side facing the noise source and one side facing away from the noise source.
  • the area facing the noise source is filled with a first filling material and the area facing away from the noise source is filled with an unbound insulating and supporting material.
  • this gabion basket is designed in such a way that the area facing the noise source occupies more than 5% and less than 50% of the entire interior volume of the gabion basket that can be filled, the mesh size of the wall of the gabion basket facing the noise source is more than 20 mm x 20 mm and less than 100 mm x 100 mm and the compacted, non-bound insulation and support material cannot be compacted further than 2 cm per meter of riser after it has been compacted.
  • the gabion basket has at least three separate areas.
  • the areas extend over the entire height and the entire width of the gabion basket.
  • the areas of the gabion basket are divided into sub-segments by at least one separating device, with at least one separating device extending over the entire height and the entire width of the gabion basket.
  • There are two sides to the gabion basket - one side facing the noise source and one side facing away from the noise source.
  • the area facing the noise source is filled with a first filling material and the area facing away from the noise source is filled with a second filling material.
  • compacted, non-bonded insulating and supporting material is filled.
  • This gabion basket is characterized by the fact that the area facing the noise source occupies more than 5% and less than 50% of the total fillable interior volume of the gabion basket, the mesh size of the wall of the gabion basket facing the noise source is more than 20 mm x 20 mm and less than 100 mm x 100 mm and the compacted, non-bound insulation and support material cannot be compacted further than 2 cm per meter of riser after it has been compacted.
  • the first and second filling material and the insulating and supporting material have a pH of 6 to 9, preferably 6.5 to 8.
  • the filling material as well as the insulating and supporting material are preferably pH-neutral. In this way, a damaging effect on the grid material of the gabion basket can be avoided, so that the long service life required for approval can be achieved.
  • the advantage of the small mesh sizes of the gabion basket is that other grain sizes of granules can now be used, for example in combination with cellular glass or cellular glass gravel.
  • the sub-segment arranged on the noise side within the gabion basket can be made narrower while retaining the sound absorption properties than with conventional coarse-grained granulates.
  • the insulation and support material filling area of the gabion basket which is normally filled with a bonded insulation and support material such as concrete, can be filled with unbonded insulation and support material such as earth or excavated soil.
  • the wider area according to the invention, provided for filling with insulation and support material thus advantageously enables mechanical compaction. This enables improved stability to be achieved.
  • the strength properties achieved is around 2 cm per vertical meter at 500 kN for the noise-side area of the gabion basket according to the invention. It is therefore advantageous to dispense with a monolithic Concrete layer, which serves to stabilize the noise barrier and the reflection of sound waves.
  • Another benefit of using a mesh size of 20mm x 20mm and less than 100mm x 100mm is the enabled use of locally available chippings.
  • the locally available chippings advantageously enhance the aesthetic appearance of the respective gabion basket, since the local landscape is preserved. Furthermore, there is an ecological and economic advantage due to a reduction in the emission of greenhouse gases and a reduction in the costs of transport and logistics, since there is no need to deliver lava gravel.
  • the gabion basket By using the mesh size of 20 mm x 20 mm and less than 100 mm x 100 mm, it is also economically possible to form the gabion basket from grid mats with eyelets welded on all sides.
  • the strength advantages of an eyelet welding are achieved in the manufacture of the gabion basket.
  • the result of these welded eyelets is that the force is mainly introduced into the gabion wire in the longitudinal direction and the forces acting, e.g. caused by the gravitational pressure of the filling materials, mainly act along the wires and are reduced on the welded connection. This property also contributes to the durability and lifespan of the gabion baskets, as it significantly relieves the potential weak point of a welded connection.
  • the gabion basket consists of a steel wire with a wire diameter of 3.5 mm ⁇ d ⁇ 8 mm and a coating of a zinc-aluminum mixture with an aluminum mass fraction of 6% to 16% and a zinc mass fraction of 94%. up to 84% trained.
  • the entire interior volume that can be filled is understood to mean the spatial area which is enclosed by the grid of the gabion basket.
  • the individual wire meshes of a gabion basket often consist of coated steel wires or uncoated high-alloy steel wires that are thermally welded crosswise to one another.
  • insulating and supporting material is understood to mean a filling material which is filled into a gabion basket or into a partial segment of a gabion basket and which is suitable for giving a wall of at least two gabion baskets stacked on top of one another increased rigidity.
  • the insulating and supporting material thus serves to reinforce the entire gabion wall.
  • a separating device is understood to mean those structural measures which require the creation of sub-segments or sub-sections within the volume enclosed by the gabion basket.
  • a sub-segment is therefore understood to mean that spatial area within a gabion basket which is separated from the volume enclosed by the gabion basket by the separating devices.
  • the insulation and support material for filling the gabion basket according to the invention has rock types from the local excavation with a sieve size of less than 0 mm -63 mm.
  • an airborne sound insulation of at least group B3 according to ZTV - Lsw 06 is already achieved by using the local soil excavation.
  • the first filling material (103) has an angle of repose of 35° to 45°, so at least the absorption of the A3 according to ZTV-Lsw 06 is advantageously achieved.
  • the angle of repose is defined by the slope of a cone of repose or a poured embankment. This applies preferably when the first filling material (103) is a mineral filling material.
  • the angle of repose is determined by measuring devices that work according to DIN EN ISO 14688-1 and DIN EN ISO 14688-2. A further determination of the angle of repose is possible by loosely packing the bulk material on a defined cross-sectional area. The angle at which material no longer moves along the embankment that is being formed is the angle of repose.
  • the filling material is selected from glass foam gravel or the group of gravel, grit, crushed stone and/or a mixture thereof.
  • the filling material is preferably gravel and/or glass foam gravel.
  • Glass foam or foam glass is a mineral lightweight building material that is produced from waste glass using an expanding agent.
  • a cellular glass gravel or cellular glass granulate is used for the invention.
  • Foam glass is characterized by its low weight and its heat-insulating properties. Glass foam is also recyclable.
  • ballast is understood to mean a broken aggregate with a grain size selected from 0/32, 0/45, 60/90, 60/120, 50/125, 60/125, 60/150, 60/180.
  • the cellular glass gravel has a sieve size of 10 to 90 mm, preferably 10 to 60 mm, particularly preferably ⁇ 32 mm-45 mm.
  • the gravel is selected from a pressure-stable and frost-resistant rock such as basalt, granite or deodorite.
  • a second filling material is used, which differs from the first filling material by the properties of the angle of repose or the granulation.
  • the second filling material has an angle of repose of 35° to 45°.
  • the second filling material is preferably a mineral filling material selected from crushed stone, railway crushed stone, gravel and/or a mixture thereof.
  • sieve size is understood to mean the mesh size of a sieve through which a body does not fall during sieving.
  • the insulating and supporting material has an angle of repose of between 32.5° and 40°. In this range of the angle of repose, the material shows the optimal properties with regard to compaction.
  • An insulation and support material with the properties mentioned can be compacted without becoming free-flowing. This means that the use of self-hardening materials as insulation and support material - such as concrete - can be dispensed with.
  • the compacted insulation and support material (102) is compacted excavated soil. This eliminates transport costs for the delivery of other insulation and support materials, for example. Thus, in addition to an economic advantage, there is also an ecological advantage, since a significant part of the CO 2 emissions are avoided when erecting a gabion wall. Furthermore, overburden is avoided as far as possible and any storage areas are not required. In addition, the recycling of the local soil does not affect the pH of the adjacent soil and thus does not disturb the surrounding ecosystem.
  • wires of the gabion basket makes it advantageous, for example but not exclusively, unalloyed wire rod made of low-carbon steel according to DIN EN ISO 16120-2 with a zinc-aluminium coating (Zn90%/Al10%) of at least 300 g/m 2 according to DIN EN 10244-1 and a durability according to DIN EN 1990 of at least 50 years.
  • the additional grid wall (104) is made of wire, the wire having a cross-sectional diameter of 4 mm to 7 mm, but preferably a cross-sectional diameter of 4.5 mm to 5 mm. This is advantageous because it increases the rigidity of the existing wire mesh of the gabion basket.
  • the range of filling materials that can be used is increased, since smaller minimum sieve sizes for the grain size of the filling materials can now be used and a further reduction in the overall weight is achieved.
  • the total weight can also be increased in order to make the resulting wall more resistant to extreme weather conditions such as storms.
  • the additional grid wall (104) has a mesh size of 25 mm ⁇ 25 mm to 200 mm ⁇ 200 mm, preferably from 25 mm ⁇ 50 mm to 50 mm ⁇ 100 mm and particularly preferably from 35 mm ⁇ 35 mm up to 50mm x 50mm.
  • the at least one separating device (105/106) consists of geotextiles and geogrids. These geotextiles and/or geogrids consist of a plastic that is difficult to decompose. Difficult to decompose is understood to mean that the material is resistant to external environmental influences such as weather and UV radiation.
  • gabion walls can also be manufactured with a long service life. This is of crucial importance, for example, but not exclusively, when erecting noise protection walls on railway lines, since a normative service life of at least 50 years is required for these structures and reliable stability is required during this period.
  • non-rotting materials made from UV-stabilized nonwovens, such as geotextiles with a geotextile robustness class (GRK) between 2 and 5 made from polypropylene and geogrids made from high-density polyethylene (PE-HD) and polypropylene.
  • GRK geotextile robustness class
  • a noise protection wall according to the invention is formed from gabion baskets arranged next to and one above the other.
  • the invention provides a gabion basket that is designed to be noise-insulating, with the materials used for the filling not having a damaging effect on the grid of the basket, so that a long service life of at least 50 years, which is required for approval, can be achieved.

  • the noise protection properties for absorbing the incident noise by at least 8 dB can be achieved with narrower sub-segments of the gabion basket than when using conventional materials such as broken lava.
  • the improved sound-absorbing properties of at least 8 dB are thus achieved due to the smaller grain size of the first filling material and the sound-reflecting properties of the unbound insulating and supporting material.
