The invention relates to the field of geogrid structures, in particular to a self-weight anchorage type geogrid structure. The self-weight anchorage type geogrid structure comprises a fixed sleeve, watering structures, locking structures, connecting structures, anchoring structures and soil fixing structures, the watering structures are arranged on two geogrid bodies, in the drought weather, watercan be automatically supplied to tree trunk roots, trunk growth can be ensured, through the locking structure, road holding of the tree trunk roots and soil is higher, the anchoring structures are arranged in the two geogrid bodies, the geogrid bodies are firmly fixed to the ground soil, the condition of geogrid body slippage caused by water and soil losses can be prevented, when the anchoring structures work, the soil fixing structures can be synchronously driven to work, through work of the soil fixing structures, the geogrid bodies and the ground soil can be more strongly fixed, due to increasing of the contact area with the ground soil, the water and soil losses can be effectively prevented, and the aim of protecting soil is achieved.
