The utility model relates to an immersed tube bottom end forklift-type rectifying and fine adjusting system which comprises a control system and a mechanical system. The mechanical system comprises a hydraulic power pack, a weight box and a rail arranged on one side of the weight box. The rail is provided with a horizontal positioning jacking mechanism which is capable of operating along the rail and comprises a base plate arranged on the rail and a horizontal positioning jacking jack arranged on the base plate. One end of the horizontal jacking jack is connected with the weight box. A vertical jacking mechanism is arranged on the base plate and composed of a vertical jacking jack arranged on the base plate and a lifting rack arranged on the top end of the vertical jacking jack. The vertical jack is arranged on the base board. One side of the lifting rack is provided with a lifting platform for bearing an immersed tube. The lifting platform is provided with a horizontal sidesway mechanism. The immersed tube bottom end forklift-type rectifying and fine adjusting system is simple and reasonable in structure, convenient to operate, accurate to position, high in installation accuracy, capable of being hardly influenced by natural conditions like waves, currents, winds and the like, and high in stability.
