Sack Gabions- Gabion Mesh Bags - Sack Gabions Mesh Body Net

Sack gabions are made of woven wire meshes into a cylindrical container after being filled with stones to used like sacks or bags for river closure and bottoming. The sack gabions mainly includes a mesh body. After the mesh body is unfolded, the butterfly-shaped net surface is closed along the edge of the net body.

There is a polygonal mesh in the mesh body. The mesh is hexagonal. When the equipment is used for interception, the riprap can be thrown in a sack gabions bag. While increasing the roughness of the bottom of the ditch, it also improves the stability of the riprap and reduces losses. Each sack gabions can be removed as a whole, thus reduce the cost and difficulty of dismantling.

Sack Gabion Features

Sack gabions or mesh bags have the following advantages:

Sack gabions have strong impact resistance, strong integrity, good corrosion resistance and good flexibility, an easy adaptation to river bed deformation, and a popular use in key dangerous sections of deep water and rapid flow.

Sack Gabions for Flood Control Solutions

Due to the difference in construction conditions, different construction techniques and procedures are adopted along the river, where the water flow is gentle and affected by tidal floods, and gabion mesh bag throwing is carried out on the turbulent rivers and along the river, which was greatly affected by tidal floods.

Sack gabions construction:

Assembly: Lay the gabion mesh bag on a flat ground, flatten the excess creases, and spirally rotate it into a cylindrical shape along one side, and fix both ends with tie wires.

Basic preparation: The foundation of the sack gabions does not need to be too flat. For the wetland environment with poor foundation environment, gabion mesh bags can be used as a fixed platform. According to the needs of the project, fill in appropriate materials, and place sack gabions bags layer by layer. It should also be structured in accordance with engineering specifications. The geotextile can be clamped in each layer of gabion mesh bag.

Seam: The gabion mesh bag is rolled into a cylindrical mesh bag similar to a cloth bag with a mesh sheet, and is tied tightly with edge wire. Adjacent side meshes are wrapped with tie wires, as long as they are tied firmly on the side of the cylinder, and then the two bottoms are tightly wound, the gabion net bag can be used. When hemming, there should be an opening for loading stones on the cylinder surface. At the same time, when hemming and installing stones, care should be taken to protect the coating on the surface of the mesh to avoid damaging it.

Positioning: After tying up, use the machine to carefully hoist the gabion net bag once or twice, and put it into the proper position. In order to ensure the quality of the product, the thicker edge wire and tie wire are used for the seam and assembly of the gabion net bag.

Sack Gabions consist of a single mesh panel made of hexagonal woven wire Mesh Type 80, commonly referred as double twisted wire mesh. Sack Gabions are filled with rocks at the project site to form a flexible, permeable and monolithic structure. This structure is used for emergency and river training in works when local conditions require fast installation, or when the water does not allow easy access to the site or when underwater installation is necessary.
