Zusammenfassung:	The utility model discloses an assistor for the over-water butt weld of large-diameter steel pipes. The assistor is mounted at a splicing area between two large-diameter steel pipes which are spliced with each other; the assistor is in a bottom sealing structure; the main structure of the assistor is in a cavity body; a water-pumping and air-exhausting port is formed above the assistor; a bow-shaped part matched with the large-diameter steel pipes is formed at the upper part of the assistor; and the bow-shaped part is arranged at a splicing gap of two adjacent large-diameter steel pipes. According to the assistor for the over-water butt weld of the large-diameter steel pipes, disclosed by the utility model, the butt-welding efficiency of the large-diameter steel pipes is increased and the construction difficulty is lowered during the process of over-water construction, and then, the construction progress of a whole pipeline project is sped up.
