The invention relates to the field of civil construction and discloses a guide deviation correcting device for large concrete component pushing. The guide deviation correcting device comprises a cover plate, guide arms, a bidirectional guide jack and connecting rods. Mounting seats are respectively disposed on two sides below the cover plate. A hinge shaft is disposed on each mounting seat. The mounting seats are connected with the upper ends of the guide arms through the hinge shafts. The horizontal two sides of the bidirectional guide jack are respectively provided with jacking ends. Each jacking end is connected with one end of the corresponding connecting rod, and a buffer gap is reserved between the jacking end and the connecting rod. The other end of each connecting rod penetrates the body of the corresponding guide arm and is rotatably connected with the guide arm. The guide deviation correcting device has the advantages that real-time monitoring of large concrete component pushing can be achieved, component deviation can be discovered timely, deviation correcting can be performed timely, and quality risks such as component damage and prefabricated dimension error standard exceeding caused by excessively-large deviation during component moving are prevented.
