The invention discloses an ultra-deep diaphragm wall steel box groove position attitude control system and a construction method thereof, a groove entering plane position limiting guide mechanism is adopted to realize coarse positioning of a steel box relative to a guide wall plane position when the steel box enters a groove; a multi-point-position large-rigidity supporting system is adopted, the non-linear influence of structural flexibility on steel box slot position posture control is reduced, and the accuracy of active control over the steel box slot position posture is guaranteed; a high-precision measurement sensing system is adopted, and efficient and accurate monitoring of the posture of the steel box is achieved; and meanwhile, active and accurate control over the posture deviation of the heavy ultra-long steel structure below the slurry liquid level in the groove section is achieved through the steel box groove position posture active control system. According to the ultra-deep diaphragm wall steel
