The pool and the pit vertical wall usually embeds the waterproof sleeve and reserves the hole according to the needs of the main body, so when designing the pool and the pit, the vertical wall should be pre-strengthened and the corresponding waterproof measures should be taken at the hole position. However, during the construction of the pool and the pit, due to design errors or omissions, or the need for equipment installation after the construction is completed, it is necessary to add large holes (D≥800mm) or enlarge the original reserved hole on the vertical wall of the pool and the pit. Therefore, for the newly added large hole, how to reinforce the hole in the vertical wall becomes the key to the safety and waterproofness of the structure. SUMMARY

[0020] The construction steps of the reinforcing structure of the utility model are as follows:

[0021] S1: when the radius of the hole of the newly added 9 is R, first, the center elevation of the hole of the newly added 9 is determined, then the concrete of the circular hole with the radius of R+350mm is chiseled on the vertical wall 1, the original vertical wall reinforcement 3 is exposed, the original vertical wall reinforcement 3 is cut off from the middle position and is bent outward;
