Drainage groove reinforced through perpendicular crossing of double anchor rods

The invention discloses a drainage groove reinforced through perpendicular crossing of double anchor rods. Transversal anchor rods and vertical anchor rods are arranged on a roadbed slope surface of the drainage groove, and are mutually parallel; anchor rod nodes are formed at the perpendicularly-crossed parts of the transversal anchor rods and the vertical anchor rods; end parts of the vertical anchor rods are fixed on an anchor cement block; and a base layer treatment layer is arranged at the top of the bottom surface of an earth base, and the anchor cement block is arranged between the base layer treatment layer and the bottom surface of the earth base. The vertical anchor rods and the transversal anchor rods are arranged on the roadbed slope surface of a base layer water guide groove of the structure, the anchor rods are mutually perpendicularly crossed and arranged, and the end parts of the vertical anchor rods are fixed on the anchor cement block, thus the stability of the roadbed slope surface of the b
