Retaining Wall Barrier

Blast fence, also known as Defensive Barrier, is a kind of modern gabion mainly used for flood control and military fortification. Here is a detailed introduction:

Composition and Structure: It consists of a collapsible wire mesh container and a heavy - duty fabric liner. The wire mesh container is made of high - carbon steel wire, which is welded by a special welding process and then undergoes surface treatment such as hot - dip galvanization or zinc - aluminum alloy coating to improve its corrosion resistance. The heavy - duty non - woven geotextile liner is flame - retardant and UV - resistant, which improves the safety and service life of the product.

Working Principle: After being unfolded, it is filled with sand, soil or gravel to form a solid barrier. The four corners of the blast fence are equipped with wire loops, which can be fixed to each other by bolts to form a continuous wall3. When filled and tamped, it can resist the impact of explosions and vehicles.

Advantages

Easy and Quick to Install: It can be quickly deployed with the help of equipment such as loaders and excavators. For example, a 9 - meter - long, 90 - centimeter - high and - deep wall can be completed by 2 people using a bulldozer in 20 minutes, while a sandbag wall requires 10 people to work for 7 hours by hand.

Good Portability: It is designed for foldable packaging, which is convenient for transportation and storage2. It can be quickly moved and deployed to the required location.

Highly Customizable: It comes in a variety of sizes and models, and most can be stacked according to needs. The filling materials can be local materials such as sand, soil, gravel, and even garbage.

Excellent Protection Performance: It has been proven to be able to defend against various light weapons, RPGs, mortar and artillery fragments, and can also withstand the impact of heavy vehicles. For example, a double - thick blast fence can withstand the impact of a 6.75 - ton truck traveling at 80 km/h, and a two - story - high, double - bottom wall can stop a 30 - ton truck traveling at the same speed within one second.

Range of Applications: It is widely used in military fields, such as being used to build base defense lines, isolation walls, mortar positions, command posts, barracks, and even around toilets in combat bases. It can also be used in civil fields, such as flood control and erosion prevention on beaches and marshes, and can be used to reinforce levees during floods.
