The core characteristics are eco-friendliness and permeability.Voids between components or pores within the blocks themselves allow water passage,reducing hydrostatic pressure while providing space for soil and plants.Plant roots can penetrate the stone gaps,reinforcing the bank and forming a green,natural landscape.It is more conducive to maintaining river ecosystem continuity than hard revetments.
This is typically not a continuous railing but a revetment system assembled from numerous small precast components(e.g.,eco-blocks,fish-nest blocks)or large gabion mesh boxes.It can be constructed in stepped or sloped configurations.The height and slope are designed according to the river's hydrological and geological conditions.
Specifically used for Sponge City projects like urban river remediation,reservoir slope protection,and wetland park construction.It not only prevents soil erosion but also restores biodiversity in the riparian zone,creating a hydrophilic environment.After construction,soil should be filled into the voids and native plant seeds sown to allow natural succession into an ecological shoreline.
