A single box gabion is disclosed. The gabion comprises interconnected side walls. Each side wall comprises at least one substantially closed side wall element panel that prevents a gabion fill material from falling through the side wall without the aid of a gabion lining material. The single box gabion can be coupled together to form a modular gabion structure to protect military or civilian installations from weapons assault or from elemental forces, such as flood waters, lava flows, avalanches, soil instability, slope erosion and the like.

A tree-planting structure device includes a securing net, an anchor, a plurality of stacking pouches and hooks. The securing net is formed in a size capable of covering a part of a guard, the ground, or a building outer wall and having an arrangement of a plurality of meshes. The anchor is coupled to the guard, the ground, or the building outer wall in order to fix a position of the securing net. The plurality of stacking pouches includes sacks coupled to the meshes for forming the securing net and respectively having plant growing soil contained therein. The stacking pouches are stacked while coming in contact with the securing net. The hooks include members for coupling the stacking pouches to the meshes of the securing net.
