Ground anchor jump-out protection cap

Abstract

As shown in the "Reference diagram showing the usage state", ground anchors are installed as a countermeasure on slopes with unstable soil masses. Ground anchors ensure the stability of slopes by burying anchor tendons (steel wires, etc.) under high tension in the ground and fastening the anchor body, which is constructed in stable ground below the slide surface, to the anchor head on the ground surface. However, there is a risk that the anchor tendons will break and fly out due to aging or unexpected heavy rain or earthquakes. To prevent this, two or more even number of protective devices containing special rubber that absorbs the flying energy are installed and fixed to the anchor pressure plate by shafts, and this item is attached between the protective device and the anchor head. In this case, the receiving part of this item is positioned in front of the anchor cap. As a result, if the anchor tendon and anchor head fly out, the flying energy is transmitted and absorbed by this item to the flying protection device, preventing them from flying far away.
