The invention discloses a pier body capping beam suspension bracket applied to an area with strong swell and low piers. The pier body capping beam suspension bracket comprises a plurality of supporting bodies, bearing cross beams and a plurality of brackets; the supporting bodies are arranged at intervals and inserted into the sea bottom; each supporting body comprises a pile foundation casing inserted into the sea bottom and a large casing fixedly arranged on the outer part of the pile foundation casing, and the pile foundation casings and the large casings are partially overlapped; the pilefoundation casings and the large casings are spaced apart from one another by a certain distance, and space between the pile foundation casings and the large casings enables operators to construct andoperate; the bearing cross beams are placed at the tops of all the large casings; and the brackets are mounted on the bearing cross beams for the pier body capping beam construction. The capping beamsuspension bracket is simple in installation, clear in force, safe and reasonable and convenient in operation, can realize the cast-in-place dry pouring construction working environment of a pier body capping beam under strong swell conditions, and protects the safety of working personnel, window period conditions required by the construction are greatly reduced, and construction conditions for an underwater pier body part is directly provided.
