This is another much larger and rigid version to make the aponix vertical barrel idea available also for public spaces – in a vandalism and fire proof form. We call it the XL or city version. It uses 9 ring segments per level (diameter 95cm) and is much more robust. It requires manual integration into a larger urban planting context along for example roads or bicycle lanes for example. Pieces can be fixed/combined using metal rivets or also metal inlays inside and rivets in combination to make have a solid structure.
On the right you can see how it looked as a prototype in an integrated way built from our existing smaller ‘white’ substrate shelf pieces.
The first shelf piece is available from early 2020.
Pieces need to be integrated into a larger context with a base, irrigation and internal logic. The idea is to have building blocks that have the following properties:
- Robust and safe for public spaces (Flammability UL94 tested and rated V-2, will not create sharp edges when it breaks).
- Can be tightened and combined into al rigid large structure using screws or rivets if required. There are different levels of stability.
- Can be assembled and disassembled at the end of the season to recycle the substrate more easily.
- Can be prepared off-site and be moved with a fork lift to the exhibition location.
- Is made from food safe material to also grow edible plants in public spaces (drastically reduces vandalism).
Please let us know if you would be interested to learn more about our City XL Vertical Barrels system! We are looking for pilot projects. Please note that, we only provide the ring segment pieces and every setup will need to be integrated setup in an individual way. You will need to build a round metal base, fill the interior with substrate a center spacing tube and perhaps also irrigation logic or connect it to a natural rainwater supply etc.
Ring Segment Pieces
There will only be two pieces available:
The small dots are drill marks that can optionally be drilled to place additional connecting rivets or screws after clicking the pieces together or stacking multiple ring segments. a) Pieces within a ring segment can be combined horizontally and/or b) stacked ring segments can be combined vertically.
Base and Integration
Mounting ring segments:
The base will be made from a custom steel element (brown) that defines the height and how the unit is anchored. The whole structure can also be mounted into a larger container that serves as water reservoir. The inside will also be customized by either inserting a heavy vertical water pipe or other structure to save substrate and weight. This will provide also space to insert pumping logic, solar panels on top or mounting structures to fix the unit in place. Please note: All this needs to be custom made.
The stacked ring segments can be combined using a ribbon made from steel or a synthetic fabric (light brown inside) that combines two ring segments with each other using the optional rivets or screws.
DImensions
Larger than the normal version:
The City XL vertical barrel will have a diameter of 95cm plus the shelves and each ring segment is assembled from 9 ring segment pieces. The material will be 3.5mm thick instead of 2mm from the normal substrate version.
The idea is that the whole structure including the base container can be filled and planted offsite and then be brought into its final position using a forklift.
