The invention discloses a shallow raft foundation building correcting method, which is characterized by comprising construction steps: (1) correcting holes are drilled; (2) earth pressure cells are mounted; (3) correcting pipes are mounted; (4) the air injection construction of the correcting pipes is carried out, and the air pressures of the correcting pipes are adjusted according to a correcting speed and the pressures of the earth pressure cells; (5) grouting reinforcement is carried out for the correcting pipes, wherein the grouting pressure is 0.3-0.4 MPa; and (6) the correcting holes are sealed, and a secondary sealing mode is adopted for sealing the correcting holes. According to the shallow raft foundation building correcting method, the safety performance is good; the correcting reliability is high; and the cost is low.
