Types of gabion mesh: gabion mesh, lead wire gabion, heavy hexagonal mesh, Reynolds pad, Cyclo gabion, reinforced mesh, welded gabion mesh, chain link gabion mesh, etc.

Gabion mesh is also called heavy hexagonal mesh, twisted flower mesh, gabion mesh, three-joint machine-woven mesh, and twisted-pair mesh. It is a cage made of angular mesh (hexagonal mesh) woven by metal wires. It varies according to the size of the hexagon. If it is a metal-coated wire hexagon, use a wire with a wire diameter of 2.0mm to 4.0mm, and if it is a PVC-coated wire woven hexagonal mesh, use the outer diameter It is 3.0mm to 4.5mm PVC (metal) wire. The wire on the edge of the outer frame is one size thicker than the hexagonal wire.

Gabion mesh is a mesh cage of various specifications made of mechanically woven double hinged hexagonal flexible metal mesh with anti-corrosion treated low carbon steel wire after cutting, edging and combination.

The twisted-pair grid structure has the following advantages:

(1) Ecological and environmental protection, the internal stone filling is a natural material, which is friendly to the environment, and plants can grow in it to meet ecological requirements;

(2) Integrity, the structure is not easy to be damaged;

(3) Flexibility, able to adapt to the deformation of the foundation without damage;

(4) Durability, the twisted-pair grid adopts coating and PVC protective film, and has a long service life;

(5) Water permeability, the interior of the structure is permeable, and no special drainage facilities are required;

(6) Low cost, less material and convenient construction;

(7) Good wave elimination performance. Therefore, it can be widely used in the construction or reconstruction of ecological river revetments to reduce the pressure on the river ecosystem caused by engineering measures.

There are three basic forms of twisted-pair grid structures used for river bank protection: cages, mats and bags. The interior of the structure is filled with pebbles or small boulders, and sometimes other materials such as discarded concrete blocks, bricks, etc.

The main difference between cages and mats is their thickness: mats are thinner than cages (about 0.15-0.5m) and are used to protect riverbeds and banks from erosion damage. The cage is thicker (about 0.5-1.0m), but covers a small area. It is used to protect the river bank where the net pad cannot be used, or to stabilize the slope, build the drainage structure, the outlet of the water pipe, or to protect the soil Any other structure that is impacted by water. Mesh bags, as the name suggests, are bag-like grids filled with rock, which can be used to build embankments or breakwaters, or in emergency engineering.

Reynolds pads, also known as gabion pads, gabion pads. Reynolds pad refers to a pad-shaped engineering component composed of machine-woven double-twisted hexagonal metal mesh, whose thickness is much smaller than the length and width, and which is filled with fillers such as blocks and connected into one, and is mainly used for water conservancy embankments. , bank slope, Hyman and other anti-scour structures have the advantages of flexibility and adaptability to the foundation. Reynolds pads are cage structures with a thickness of 0.15-0.3m (including 0.3m). It is mainly used as a slope protection structure for river courses, bank slopes and roadbed slopes. It can not only prevent the river bank from being damaged by water flow, wind and waves, but also realize the natural convection exchange function between the water body and the soil body under the slope, and achieve ecological balance. Planting green on the slope can add landscape and greening effect.

The Reynolds pad is divided into several cells by the partition. In order to strengthen the strength of the Reynolds pad structure, all the edges of the panels are made of steel wires with larger diameters.

Specifications and features of Reynolds pads: (1) Improve the stability of riverbed slopes. (2) Protect the riverbed from scouring. 3. Provide the predetermined value of the bank roughness factor (m). 4. The greening and ecological protection of slope protection and bank protection, and the development and management of river channels involve the construction technology of laying guard pads with equal sections. Laying of pads, pads with permanent protection can be used on river banks.

Gabion mesh, also known as gabion mesh bag, is a cylindrical bag woven by double-twisted hexagonal metal mesh, in line with ASTM A975-97 standard. During the construction process, the mesh bag is filled with prefabricated stones to form a building material with strong structure and strong permeability, which is used in various emergency preparation projects such as river protection. In the process of weaving the mesh bag, thicker wire is embedded in the mesh bag for the convenience of knotting. In the process of silk forming and weaving, all links of the gabion mesh bag have undergone strict standard testing. All selected wires, including radial and weft wires, galvanized quantity, and bundled wires must meet the standard of ASTM A975-97, that is, the tensile strength shall not be lower than 75000psi (515Mpa) - ASTM A641/A641M-03.

Cyclops installation

(1) Material transportation Cyclops is a woven mesh, which is woven through a series of procedures such as wire selection, mesh weaving, cutting, crocheting, and inspection. Gabion nets can be rolled, or the cages can be compressed and packaged, so that workers can pack and ship the process, and the binding wire is provided in rolls. It is best to put the gabion in a dry environment and tie it tightly for easy shipping.

(2) Assembly Place the sekgebine on a flat ground, flatten the excess creases, spirally rotate along one side into a cylinder, and fasten the ends with binding wires.

(3) Foundation preparation It is not necessary to place the foundation of the Sek Gabion. In the wetland environment with poor foundation environment, the gabion net can be used to provide a fixed platform. According to the needs of the project, load the appropriate materials, and place the Cyclops in layers. The gabion structure also conforms to engineering specifications. Geotextiles can be sandwiched between individual gabion layers.

(4) Sewing edge Seck gabion is made of mesh rolled into a cylindrical wire mesh like a cloth bag, and tied with edge wire. Twist the mesh and the edge wire adjacent to the edge with the tie wire. As long as the side of the cylinder is tied, and then the two bottoms are wrapped tightly, the sekgebine can be used. When seaming the side of the cylinder, an opening for loading stones should be left. At the same time, attention should be paid to protecting the surface coating of the mesh when sewing and loading stones to avoid damage.

(5) Placement After tying, use the machine to carefully hoist the sekgebone one by one or two by two into the proper position. In order to ensure the quality, the gabion mesh should be sewn and assembled with thicker edge wire and binding wire.

Each gabion cage of electric welded gabion net is made of high galvanized steel wire, which has strong firmness and corrosion resistance. In order to improve the service life of the cages, Gabion Industry has launched the PVC cladding technology through strict standardized testing (ASTM), and now this technology has been proficiently applied in the production process of gabion nets.
