Abstract
The present invention discloses a process method for withdrawing and recovering a mechanical constant-resistance single prop, specific steps involving: detecting a working resistance and a degree of deformation of a mechanical constant-resistance single prop, releasing lug clamp bolts of a recoverable base, knocking a lower portion of a cylinder body of the mechanical constant-resistance single prop to disengage the mechanical constant-resistance single prop from the recoverable base, and dismantling the mechanical constant-resistance single prop. Parts are classified and recovered based on degree of deformation thereof. By means of the foregoing method, a process of withdrawing and recovering a mechanical constant-resistance single prop is standardized, simple and fast disengagement of the mechanical constant-resistance single prop is achieved, and parts that can still be used can be sufficiently recovered and reused, thereby achieving the objectives of saving energy and reducing costs.
