The invention provides a diversion canal underwater control excavation system and a construction method. A diversion canal underwater accurate measurement technology, a drilling platform rapid positioning technology, an underwater rapid drilling technology and an underwater hydraulic control rock excavation technology are adopted. The construction method comprises the main construction steps of accurate underwater terrain measurement of the diversion canal, drilling platform machining and underwater positioning, underwater rapid drilling construction, underwater hydraulic control rock excavation and underwater gravel removal of the diversion canal. The underwater topographic measurement precision of the diversion canal is high; the drilling platform is good in stability, rapid in positioning and convenient to move; the underwater multi-point pore-forming operation is realized, and the construction speed is high; rock excavation is hydraulically controlled underwater, related equipment can be repeatedly constructed, the construction speed is high, in addition, the problems of large pollution, high construction requirements and the like in blasting operation construction are solved, compared with a traditional construction technology, the method is high in construction speed, free of pollution and controllable in cost, remarkable economic, environment-friendly and social benefits are achieved, and good application and popularization prospects are achieved.
