FIELD: mining.
SUBSTANCE: invention relates to mining, namely to anchors for fastening the walls of underground mines and tunnels, and can be used for installation in various types of rock, for example, when fastening metal structures to the walls of mines and tunnels, as well as for installation in concrete surfaces at any type of construction. The device is made in the form of a rod with wedges located on it. The rod is formed by a cylindrical or flattened cylindrical surface, on the rod there are limiter rings, between which wedges are inserted, attached to the rod with the help of clamps with the possibility of destroying their mutual connection when the rod is rotated in the hole and holding the rod inside the hole due to its wedging in the hole.
