Ground anchor device suitable for saturated sandy soil site

The invention discloses a ground anchor device suitable for a saturated sandy soil site. The ground anchor device comprises a drill rod and a drill bit. The drill bit is installed at the bottom end of the drill rod, and a plurality of water permeable holes are evenly distributed on the wall of the drill rod. The ground anchor device aims at reducing and solving the problem that in the process that a traditional ground anchor device drills into the saturated sandy soil site, overlarge disturbance is generated, and therefore, wide-range liquidation occurs to sandy soil around a ground anchor as much as possible. The water permeable holes are formed in the outer side of the drill rod. In the drill rod in-soil process, excess pore water caused by disturbance can permeate into the drill rod through the water permeable holes so that dissipating of the excess pore water is accelerated, therefore, the liquidation occurring possibility is reduced, and the pulling-resistant property of the ground anchor drill rod is en
