Design of blast protection wall
2 different types of blast protection wall it invited with critical site conditions.
There are
1. permanent and prefabricated concrete wall
2. semi-permanent wall. (HESCO bastions)
The permanent and prefabricated concrete wall is no necessity for that advanced planning and designing of the multi-purpose system of army trench base of a concrete bunker. Because bunkers wall are already designed in 250mm structural member in the concrete wall. It needs only exterior protection of bunker wall for high shock impact high yield blast. It takes of second protection coat barrier of semi-permanent wall Hesco bastion. Hesco Bastion is an updating of the gabion. Gabion means a bags or cage filled with the sand and rocks used in the constructions barriers or military applications [31]. And its modern days used in the application of blast wall opposition of explosion and small arms weapons. Its contains preparation wire mesh reinforced with heavy-duty fabric wire liner. It conceptually makes with the origination of Brittan used against to control the soil erosion and flood controls barriers. Developed in the late period of the 1980s by an England company. Hesco mil quickly is development by Jimi Haselden he is a British entrepreneur. Hesco mil bags assembling progress is filled rock and sand in-unit wise using a pay-loader. Main advantages of Hesco bastion barrier protect the lateral shock impact blast and most strong and flexibility of tightening filler. It will stop the 9mm projectile short-range shooting sites. Hesco sand barriers make the quick and fast to setups in emergencies conditions or previously filled hesco Baston bags takes place to use of front end loader and fixed the warzone areas. working operation is similar to the normal sandbags stodgy to place it. The Hesco barrier comes in a variety of sizes most of the barrier can compact sizes for examples (4.6x3.6x32.2 feet) to (6.9x4.9x98.4 feet). Filled with compacted sand or soil and hoisted with the mobile crane to take place in ships to get critical site conditions. Modern Hesco bastion gabion bag barriers make in a military update for bunkers and used in critical building sites for prevented to the high impact bombs [32]. This is dragged along the streak of ground barriers to formed. Unfolded Hesco gabion bags are fixed in a more than a few hundred meters of barriers ready for filling within hardly some minutes. Hescon bags are used in these Army Trench Base of Concrete Bunker it provided in exterior walls.
