1. Anchor frame beam is a kind of structure used to support earthwork slope and prevent landslide and collapse. Skeleton slope protection is a slope protection structure to prevent the collapse of earthwork slope.

2. Anchor is a kind of steel bar used to fix soil or rock. It is buried underground, and the earthwork on the slope is connected with the anchor rod by prestress or other methods to enhance the stability of the slope. Skeleton slope protection is composed of steel mesh or grid structure, which bears the gravity and horizontal force of soil, thus stabilizing earthwork slope and preventing earthwork sliding on the slope.
