Cast-in-place pile leaking stoppage hole reinforcing method and structure

The invention discloses a cast-in-place pile leaking stoppage hole reinforcing method and structure. Before a cast-in-place pile is constructed, a grouting influence radius test is carried out, a slurry influence radius is detected, a leaking stoppage hole and a wall reinforcing hole are formed around a cast-in-place pile hole, slurry is injected into the leaking stoppage hole and the wall reinforcing hole, after the slurry is solidified, construction of the cast-in-place pile is carried out, and an easily-leaking easily-collapsing layer around the cast-in-place pile can be reinforced. The method and structure are suitable for construction of the cast-in-place pile of the easily-leaking easily-collapsing layer such as gravel, cobble and limestone, the construction steps are reasonable in design, operation is easy, quality problems of slurry leaking, hole collapsing and the like in the construction process of the cast-in-place pile can be effectively solved, continuity and smoothness ofthe construction of the
