Gravity anchor capable of realizing 360-degree rotational anchoring

The invention discloses a gravity anchor capable of realizing 360-degree rotational anchoring, and relates to the technical field of anchoring. The gravity anchor capable of realizing 360-degree rotational anchoring comprises an anchor block and a steel cable, wherein an open cavity is formed in the anchor block, the cavity is shaped like a cone with a conical tip facing downwards, a hemispheric hollow iron cast is provided at the conical tip, a through hole is formed in the top of the spherical surface of the hollow iron cast, so that the hollow iron cast is communicated with the cavity; at least one arc-shaped steel ring is fixed on an internal sidewall of the cavity; a cold casting anchor head is fixed at one end of the steel cable, and is located at the internal part of the hollow iron cast, and the other end of the steel cable goes through the through hole and extends to the external of the cavity. The gravity anchor disclosed by the invention is capable of realizing 360-degree rotational anchoring, is convenient for anchor casting, is adaptive to mooring in different directions, and solves the problem that a conventional concrete anchor block difficultly ensures that an anchor rope is kept consistent with an anchor socket at one side of the concrete anchor block in direction.
