Solid deflagration expansion fixed type ultrasonic drilling anchoring device and method

The invention relates to a solid deflagration expansion fixed type ultrasonic drilling anchoring device and method, and belongs to the technical field of ultrasonic drilling anchoring. The problem of insufficient anchoring force is solved. Comprising a feeding device and a drilling anchoring device, the feeding device is matched with the drilling anchoring device, the feeding device is used for driving the drilling anchoring device, and the drilling anchoring device is used for achieving fixation. When a certain drilling depth is reached, the solid fuel in the cavity at the end part of the drill rod is ignited through electrode ignition, the solid fuel nitrocellulose is ignited, severe combustion and explosion occur, a large amount of energy is generated, and the end part of the drill rod is extruded and deformed; the deformed expansion cavity can extrude the inner wall of a drill hole to generate certain expansion force, large effective anchoring force is provided for the whole device, fixing of the whole de
