What advantages does the gabion mesh have in water conservancy projects?

Gabion mesh has permeability. The voids between the stones in the mesh provide sufficient flow areas, reducing hydrostatic pressure, and eliminating the need for special drainage devices and concrete devices prone to cracking. When used in protection projects in areas with strong winds and waves, the pores between the stones greatly reduce the impact of the winds and waves when they hit the mesh mattress. The vacuum suction force generated when the winds and waves recede is also disrupted, effectively achieving the protective effect.

The pores in the gabion boxes and mesh mattresses create conditions for water flow, which is conducive to the natural exchange between water and soil, and creates a living environment for aquatic organisms and microorganisms. This enhances the self - purification ability of the water body, protecting and improving the water source and water quality. The pores of the filling material, after being paved with soil layers artificially or naturally deposited, create conditions for greening and vegetation. Even without sowing seeds, plants will naturally grow, achieving the optimization and beautification of the environment, as well as the improvement and restoration of the ecological environment.

In water conservancy projects, the application of gabion mesh is very cost - effective. The gabion mesh system consists of wire cages and filling materials, which is lower in cost than general building materials. The filling materials only need to be weather - resistant and have a certain strength. Usually, stones of different grades at the project site can be used as fillers. Sometimes, even some relatively clean construction waste can be used as fillers, so the cost is low. Especially when the foundation conditions are poor, the cost of foundation treatment, which accounts for a large proportion of the project cost, can be saved.
