Construction method for actively controlling deformation of buildings and structures through multi-row grouting

The invention discloses a construction method for actively controlling deformation of buildings and structures through multi-row grouting. The construction method comprises the following steps that the number and positions of multi-row grouting holes located between the buildings and structures to be corrected and a foundation pit and the range of grouting expansion areas in the grouting holes are obtained through theoretical calculation or numerical simulation calculation; grouting pipes are prepared, each grouting pipe is composed of a pipe A and a pipe B which are bound together, the axes of the pipe A and the pipe B are parallel, the top faces of the pipe A and the pipe B are flush, the length of the pipe B is larger than that of the pipe A, and the area between the bottom wall of the pipe B and the bottom wall of the pipe A is a grouting expansion area; grouting holes are drilled through a drilling machine according to the preset positions; a foundation pit is excavated on the inner side of an undergroun
