![]() ![]() The model is provided in 1:10 scale (metric), for you to re-size to your desired print scale. I have been as accurate as I can, I have also made design decisions to thicken up some components for durability when printing. The models have been designed from technical drawings and various online images. fence post holes, lifting holes, bridge pier support points). I selected a barrier design that has more interesting features to add interest to an otherwise simple object (e.g. The two models for K-rails are as show with a tapered end unit, and the main rail. During the US occupation of Iraq jersey barriers were set up in cities as form of urban warfare to combat Iraqi resistance. Sometimes they are deployed to form a chicane to slow vehicular traffic arriving at military installations or other secure areas. Head-on vehicle collisions are minimized by gradually lifting the vehicle and pivoting it away from oncoming vehicles and back into traffic heading in its original direction. In common shallow-angle hits, sheet-metal damage is minimized by allowing the vehicle tires to ride up on the lower sloped face. The design of the Jersey barrier was specifically intended to minimize damage in incidental accidents and reduce the likelihood of a car crossing into oncoming lanes in the event of a collision. The walls provided in this set have a variety of damage, scrapes, impact marks, exposed aggregate, and exposed steel reinforcing, as well as a single undamaged wall unit. ![]() Much like HESCO bastions, t-wall barriers were commonly used as perimeter fortifications of forward operating bases during the War on terror. As a result, Bremer walls are capable of stopping or deflecting even the most powerful explosive devices. A slight recess is provided in the top to allow a sand & grit texture for more realism.Ī precast concrete barrier primarily used to provide protection against improvised explosive devices (IEDs), rocket attacks, and other forms of indirect fire. I’ve also given the faces of the HESCO a more natural bulge from the earth fill. Both the concertina collapsible sided version and simple square units are included, with the spiral wire jointers modelled into the design. Single and double high models are provided. The HESCO models are the most common MIL-1 format 1.1m square by 1.4m tall. Originally designed for use on beaches and marshes for erosion and flood control, the HESCO barrier quickly became a popular security device in the 1990s. It has seen considerable use during the War on terror in Iraq and Afghanistan. A collapsible wire mesh container and heavy duty fabric liner, and used as a temporary to semi-permanent levee or blast wall against small-arms fire and/or explosives. ![]()
