How to Assemble HeslyBarrier?
Brief Info of Hesly Defensive Barrier
The HESLY Defensive Barrier is a modern gabion used for flood control and military fortification. It is made of a collapsible wire mesh container and heavy duty fabric liner, and used as a temporary to semi-permanent dike or barrier against blast or small-arms. One of the less heralded life- and labor-saving devices of war, it is used on nearly every United States Military base in Iraq as well as on NATO bases in Afghanistan.
Originally designed for use on beaches and marshes for erosion and flood control, this gabion barrier quickly became a popular security device in the 1990s.
Assembling the Defensive Barrier entails unfolding it and (if available) using a front end loader to fill it with sand, dirt or gravel. The placement of the barrier is generally very similar to the placement of a sandbag barrier or earth berm except that room must generally be allowed for the equipment used to fill the barrier. The main advantage of Military Barrier, strongly contributing to their popularity with troops and flood fighters, is the quick and easy setup. Previously, people had to fill sandbags, a slow undertaking, with one worker filling about 20 sandbags per hour. Workers using Military Barrier and a front end loader can do ten times the work of those using sandbags.
The HeslyBarrier come in a variety of sizes. Most of the barriers can also be stacked, and they are shipped collapsed in compact sets. Example dimensions of typical configurations are 4'6"x 3'6"x 32'(1.4m x 1.1m x 9.8m) to 7'x 5'x 100'(2.1m x 1.5m x 30m).
A new system of Hesly Barrier developed specially for military use is deployed from a container, which is dragged along the line of ground where the barrier is to be formed, unfolding up to several hundred meters of barrier in minutes, ready for filling with soil by a backhoe.
Filled with sand, 60 centimetres (24 inches) of barrier thickness will stop rifle bullets and shell fragments. It takes 1.5 metres (five feet) of thickness to prevent penetration by a rocket propelled grenade round. Approximately 1.2 metres (four feet) of thickness provides protection against most car bombs.
