Welded Gabions for Military Fortification and Flood Control

Welded mesh gabions, enhanced with sturdy mesh panels and robust zinc corrosion protection, serve as optimal materials for constructing military defensive walls and security barriers.

Wire Material

Options for the wire material in these military barriers include hot-dipped galvanized wire, PVC-coated hot-dipped galvanized wire, Zn-10%-Al wire, and Zn-5%-Al wire.

Structure of Military Cells

Gabion barriers consist of collapsible wire mesh cages paired with heavy-duty fabric liners. The assembly incorporates distinct cover, side, and bottom panels, conjoined into a basket, secured with either lacing wire or hog rings. To fortify the mesh baskets, selvedge wire, thicker and stronger than the mesh wire, reinforces the welded mesh panels.

Wire diameter: 3.0-6.0mm
Spring selvedge wire diameter: 4.0mm
Gabion mesh opening: Various sizes including 5050mm, 7575mm, 76.276.2mm, 100100mm, etc.
Geotextile:
Heavy-duty non-woven polypropylene is employed, available in sand, beige, and military green colors.

Gabion Barriers Features

Economical: Simply fill the gabion containers with stone or sand and seal them.
Easy Installation: Achieve quick and straightforward setup and completion.
Durability: Resistant to weather damage and corrosion.
Sturdy: No collapse, even under substantial pressure.
Solid Structure: Robust and stable once assembled.
Permeability: Excellent permeation prevents hydrostatic damage.
Cost-Efficient Transport: Lower freight costs due to materials.
Versatile: Can be utilized in conjunction with barbed wire.

Installation and Forming of Gabion Barriers

Using welded mesh panels, spiral binders, pins, and sand, follow these steps:

• Panel Positioning: Place front and back mesh panels upright on the bottom panels.
• Securing Panels: Affix panels by threading spiral binders through mesh openings in adjacent panels.
• Stiffener Placement: Insert stiffeners across the corners, 300mm from the corner, to provide diagonal bracing. Crimp them over the line and cross wires on the front and side faces.
• Filling Gabions: Add stone or sand to the gabions.
• Sealing the Top: Close the lid and secure with spiral binders at the diaphragms, ends, front, and back.
• Stacking: When stacking tiers of welded gabion boxes, use the lid of the lower tier as the base for the upper tier. Secure with spiral binders and add pre-formed stiffeners to exterior cells before filling with sand.
• Extending Units: Utilize provided joining pins to extend and connect units.

Applications

Welded gabions have been notably utilized for numerous applications, including military fortifications and flood control. These structures are particularly lauded for their robustness, flexibility, and ease of assembly. Below are detailed uses in the contexts of military applications and flood control.

Military Fortification

• Blast Walls:
  Minimizing Blast Impact: Welded gabions can absorb and deflect blasts, reducing the risk to nearby personnel and structures.
  Barrier to Shrapnel: They act as a shield, preventing shrapnel from blast and explosions from inflicting widespread damage.
• Bunkers and Safe Havens:
  Quick Setup: Soldiers can rapidly assemble gabion bunkers, providing immediate shelter during conflict.
  Protection: These structures offer a robust shield against small arms fire and indirect artillery impacts.
• Observation Posts:
  Enhanced Visibility: Raised welded gabion structures provide an elevated platform for improved surveillance.
  Cover: They provide a secure cover for personnel while monitoring enemy activities.
• Checkpoint and Border Control:
  Restricting Movement: Gabions serve as impenetrable barriers that hinder unauthorized crossings at borders.
  Control Points: They fortify checkpoints, protecting personnel and equipment from attacks.
• Trenches: Trench Stability: Lining trench walls with gabions prevents collapses and provides a more durable defensive structure.
  Safe Passage: Secure, fortified trenches ensure troops can move safely between positions.

Flood Control

• Retaining Walls:
  Erosion Control: Gabion retaining walls prevent soil erosion, stabilizing banks against water flow.
  Diverting Water: These walls guide floodwaters away from vulnerable areas, mitigating damage.
• Levee and Dam Construction:
  Levee Strengthening: Gabions fortify levees, preventing breaches during high water events.
  Creating Dams: Small gabion dams can control water flow, safeguarding downstream areas.
• Riverbank Protection:
  Structural Integrity: They ensure that riverbanks maintain their structure, even with the constant stress from flowing water.
  Vegetation Growth: Promoting vegetation by providing a stable base, which further stabilizes the bank.
• Channel Lining:
  Guided Flow: Gabions are employed to line and strengthen channels, ensuring efficient, directed water flow.
  Preventing Overflow: Sturdy channel walls mitigate the risk of overflow during heavy rainfall.
• Culvert Protection:
  Stabilizing Inflows: Gabions can stabilize areas around culverts, minimizing erosion from inflowing water.
  Securing Outflows: They prevent erosion at outflow points, maintaining structural stability.
• Bridge Protection:
  Scour Mitigation: Placing gabions around bridge piers minimizes scouring caused by water flows.
• Structural Defense: Protecting bridge abutments against erosion ensures longevity and safety.
  

Welded gabions, with their adaptability, rapid installation, and cost-effectiveness, find extensive usage in both military fortification and flood control. These applications underscore their vital role in safeguarding infrastructure and lives across varying scenarios and environments.
