The invention discloses a construction control method for a large direct-buried steel anchor fluke embedded part. The construction control method comprises the steps of pouring concrete under a corbel steel bar cage or a frame beam, burying the bottom ends of supporting angle steel in the concrete, enabling the top ends of the supporting angle steel to be higher than the upper surface of the corbel steel bar cage or the frame beam, using a leveling instrument to mark the height of the bottom face of an embedded part steel plate on each angle steel and then cutting off redundant portions; placing a positioning frame on the corbel steel bar cage, enabling four corners to be welded and fixed with the corbel steel bar cage through electric welding, placing a piece of square steel slightly larger than an anchor plate into one hole after the hole is adjusted, sequentially adjusting steel bars at the anchor fluke positions, hoisting the embedded part to the position right above the installing position and slowly placing the embedded part on the supporting angle steel, wherein the bottom of the embedded part is in direct contact with the top ends of the supporting angle steel. By adopting the construction control method, the installing time can be shortened, and the installing accuracy can be improved.
