| description | The invention belongs to the field of substation equipment foundation repair, and particularly relates to a substation equipment foundation repairing device and method. The repairing device comprises a steel chisel arranged on a concrete foundation and located above the ground plane, an I-shaped steel beam arranged above the steel chisel, hydraulic jacks arranged on the ground plane, located at the two ends of the I-shaped steel beam and used for supporting the I-shaped steel beam, and a steel wire rope sleeve connected between the steel chisel and the I-shaped steel beam. And at least one grouting pipe is arranged between each of two depth positions at the bottom of the concrete foundation and the ground plane. High polymer materials and expansive concrete are injected twice before and after the repairing device lifts the concrete foundation through the grouting pipes at different positions, filling is compact, repairing is accurate, rigidity is large, and the effect of stabilizing the concrete foundation is |
