Construction method for newly forming hole in current pool wall hole

The invention relates to a construction method for forming a new hole in a current pool wall hole. Comprising the steps that the surface of a current pool wall hole is washed clean and scabbled; reinforcing steel bars are implanted around the current pool wall hole, newly-added pool wall blocking longitudinal bars are bound at the hole, and the newly-added pool wall blocking longitudinal bars are connected with the implanted reinforcing steel bars in a welded mode; positioning and lofting the position of a newly-formed hole, completing hole forming, and embedding a water stop rubber strip which expands when encountering water into the periphery of the newly-formed hole; part of longitudinal bars of the current pool wall are reserved; newly-added ring beam reinforcing steel bars are bound on the inner side of the newly-formed hole, and the original pool wall reserved reinforcing steel bars and newly-added pool wall blocking longitudinal bars are connected with the ring beam reinforcing steel bars in a welded m
