The invention relates to an anchor rod-starlike component-ball foundation. The anchor rod-starlike component-ball foundation comprises a starlike component, one or more anchor rods, cushion plates matched with the anchor rods, and anchor plates matched with the anchor rods, wherein the starlike component is embedded into a soil foundation, and the upper surface of the starlike component is flush with the ground surface; the starlike component is provided with a plurality of extension arms extending in the radial direction, and an anchor rod hole I is formed in the center of the starlike component; an anchor rod hole III is formed in the center of each cushion plate; each anchor rod comprises a rod body and a plurality of supporting rods hinged to the lower portion of the rod body; a waterproof explosive provided with a detonator is mounted around the position, above hinge joints of the rod body and the supporting rods, of each rod body, and the multiple supporting rods hinged to each rod body are overturned to the upper end of the corresponding rod body and bound to the periphery of the corresponding waterproof explosive; the bottom ends of the anchor rods and the multiple supporting rods hinged to the corresponding anchor rods are anchored to expansion heads; and the top end of each anchor rod penetrates through the anchor rod hole I in the corresponding position of the starlike component and penetrates through the anchor rod hole III in the corresponding cushion plate to be connected with the corresponding anchor plate. The invention further discloses a construction method of the foundation. The structure is simple, and the investment is reduced.
