I hope that gives you a good idea on how we quickly created a fairly secured compound (and shooting range barrier). Lastly, towers would be placed at the corners to provide over-watch, and a mortar pit created to shoot/hold ammo that, if hit, wouldn't blow up everything inside. then lastly, a triple-strand C-wire ring on top would be permanently installed to prevent people from climbing over. Once the perimeter was built with ECP (Entry Control Point - meaning a winding entrance so no one could drive straight thru to force entry and blow us up), another ring inside that perimeter would be build (2 deep now) and then stack one vertically on top of the other 2. Being rocky/mountainous (with loose dust/dirt in the areas I was in), we could have a football field sized area perimeter secured in about 2 days (with a team or two of engineers). typically, initial row would be built with the largest sized Hesco barrier we had around the perimeter. This would give it greater ability to stop bombs, mortars, rockets, & shrapnel fragments. Next we would fill it with fairly large rocks and then gravel, then dirt. Predominantly, we would open the steel caged designed box and place where it will remain. If you've a got a backhoe and/or skid loader, you can fairly rapidly create a solid wall. When we arrived at a location that would be made into a COP (Combat Outpost) or expansions to existing FOB (Forward Operating Base), we would get pallets/bundles of these delivered by CH-47s. The come in a few different sizes and they are not really for structural value but for Force Protection. in fact, I was actually stationed at the location of this picture. I assisted in the construction of several of these in Afghanistan. I realize that this is a somewhat older thread now. The exterior is formed by modular wire mesh gabions containing locally quarried stone this construction allows air movement through the building and creates an environment of moderate temperatures inside. Gabions have also been used in building, as in the Dominus Winery in Napa Valley, California by architects Herzog & de Meuron, constructed between 19. Gabion walls are usually battered (angled back towards the slope), or stepped back with the slope, rather than stacked vertically. Gabion stepped weirs are commonly used for river training and flood control the stepped design enhances the rate of energy dissipation in the channel, and it is particularly well-suited to the construction of gabion stepped weirs.Ī gabion wall is a retaining wall made of stacked stone-filled gabions tied together with wire. Gabions are also used as fish screens on small streams. They may be used to direct the force of a flow of flood water around a vulnerable structure. Other uses include retaining walls, temporary floodwalls, silt filtration from runoff, for small or temporary/permanent dams, river training, or channel lining. The most common civil engineering use of gabions was refined and patented by Gaetano Maccaferri in the late 1800s in Sacerno, Emilia Romagna and used to stabilize shorelines, streambanks or slopes against erosion. The current wikipedia entry on them says:Ī gabion (from Italian gabbione meaning "big cage" from Italian gabbia and Latin cavea meaning "cage") is a cage, cylinder, or box filled with rocks, concrete, or sometimes sand and soil for use in civil engineering, road building, and military applications. They are very useful for many permaculture purposes, although perhaps most often as water and soil management structures. You can make your own out of wire fencing, probably at less cost. Jared, those look to my eye like a military-engineering version of a gabion.
