👉️ Detailed construction instructions for woven gabion:

Gabion is an ecological construction method that involves placing "scattered stones" into a "hexagonal twisted metal mesh cage" to form a cohesive, flexible, and permeable support structure. Suitable for common engineering scenarios such as river slope protection, retaining walls, and embankment reinforcement. 1 Open the mesh cage → 2 assemble and shape → 3 connect and fix → 4 fill with stones → 5 cover and bind → 6 cover with soil and backfill: the six step systematically explain the complete process and engineering characteristics.

✅ Preparation before installation：


1. Material preparation：
• Woven gabion mesh(often galvanized or PVC coated steel wire)
• Binding wire(made of the same material as the mesh, approximately 1 meter long)
• Stone(particle size 8-20cm, strength meets standards, size matching)
• Wooden stakes or support rods(used for temporary fixation)
2. Tool preparation：
• Pliers, wire cutters, gloves, goggles
• Hammer, electric drill (if ground fixation is required)
• Measuring ruler, level (ensure neatness)
3. Site preparation：
• Clean the base, level the ground or slope surface
• Maintain the original terrain and avoid obvious uplift or depression

✅ Assemble woven gabion：
Step 1: Unfolding and Assembling
• Spread the folded gabion mesh flat and unfold it into a box shape
• Stand up the front and rear panels, side panels, and partitions to form a rectangular box
• Use binding wire to spiral wrap and fix adjacent edge wires, with a pitch of ≤ 50mm, to ensure firmness
Step 2: Connect multiple net cages (such as building walls)
• Connect the upper and lower corners of adjacent net cages with double stranded binding wires
• Tie every 200mm at the upper and lower frame lines or fold lines
• Connect the same layer of net cages together to avoid misalignment or through seams
Step 3: Fill the stone material
• After all the cages on the same layer are in place, they should be uniformly filled with stones to avoid deformation
• The height difference between adjacent net cages filled with stones is ≤ 35cm
• Use pebbles with a diameter of ≥ 10cm on the exposed surface, manually lay them flat to prevent water flow from emptying them
• Stone filling should exceed 2.5-3cm, leaving room for settlement
Step 4: Cover the lid
• After the stone filling is completed, tighten and flatten the net cover tightly
• Use binding wire to screw and fix the cover plate and the box body, with a pitch of ≤ 50mm
• Check if all connection points are secure to prevent bulging or loosening

✅ Installation precautions：

project	requirement
Placement of net cages	Arrange staggered seams to avoid longitudinal through seams
Binding wire	Wrap at least 3 times at each point, and tie the four corners together
Stone selection	The compressive strength meets the standard, and the use of fragile or flaky stones is prohibited
structural stability	When installing multiple layers, the upper and lower layers should be arranged in a staggered manner to form a whole
vegetation restoration	After sealing, 10-15cm of humus soil can be laid, which is beneficial for vegetation growth

✅ Structural characteristics and engineering advantages：

• Flexible Whole:
• The double stranded mesh allows for a differential settlement of 10-20 cm without cracking, making it more suitable for soft foundations and frost heave than rigid retaining walls.
• Permeable and impermeable pressure:
• The porosity between stones is 15-30%, which can instantly dissipate the pore water pressure behind the wall and reduce the risk of sliding; At the same time, the river water can freely enter and exit, avoiding the foot erosion caused by traditional "water blocking walls".
• Eco friendly:
• The stone crevices accumulate over time and grow aquatic plants, forming a composite habitat of "fish nests+vegetation"; The green restoration of the bank slope is fast, and the landscape is natural.
• Economically efficient:
• Local materials can be used to utilize valley stones; Construction does not require templates or cement, with a daily filling capacity of 80-120 m ³ per worker. The cost is about 50-70% of that of a concrete retaining wall, and the construction period is shortened by one-third.
• Durability and Safety:
• High galvanized+PVC dual anti-corrosion, with a service life of ≥ 50 years; The anti impact flow rate can reach 5-6 m/s, and can withstand 1-2 tons of rolling stone impact. It is commonly used in fast and rolling stone river sections.

✅ Typical application scope：

• River bank slope and embankment foot groove erosion prevention;
• Slope support for mountainous highways and railways;
• Ecological fish nest wall in the subsidence zone and landscape lake of the reservoir area;
• Urban mountain flood gullies and debris flow drainage channels;
• Temporary rescue and rapid formation of a "stone cage drum" for filling and plugging leaks

📌 Supplementary suggestions (can be adopted according to the project situation)：

• All participants should receiveconstruction safety technical briefingand pre job training.
• The homework site should be equipped with a first aid kit and a designated person should be responsible for on-site safety inspections.
• When it rains or the ground is soft, high-altitude operations should be suspended to prevent slipping and structural instability.
