Abstract: A truss-like hydraulic lifting apparatus with plugs including a pile reinforcing frame, a truss structure extending through and mounted within the pile reinforcing frame and a first number of uniformly disposed support legs, each having a support leg inserting hole. A first number of power source devices each has a plug corresponding to the support leg inserting hole. A detachable mechanism is provided for detachably fixing each of the power source devices to the pile reinforcing frame. The detachable mechanism includes a base plate laterally fixed relative to the pile reinforcing frame and having an opening through which the support leg vertically passes and forms a protective cap above the power source device. The lateral dimension of the protective cap is larger than the lateral dimension of the power source device.
