The QIAOSHI's ,石笼网Military Barriers or Hesco Bastions 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.
Assembling the Hesco Bastion 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,wire-Gabions, is the quick and easy setup. Previously, people had to fill sandbags,不锈钢电焊网-Barbed Wire,gabiony basket,hesco barrier-Military Barriers, 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 Hesco Barrier 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 46" x 36" 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 Hesco Bastion developed specially for military use is deployed from a container,楼梯踏步板, 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.
Originally designed for use on beaches and marshes for erosion and flood control, the Hesco Bastion quickly became a popular security device in the 1990s.
