Foundation pouring (including circulating water tank in the first phase) → anti-well drilling rig mobilization and installation (including high-pressure well flushing pump), initial positioning of survey, pilot hole construction → drill bit exposed at predetermined depth (if not exposed, expansion and excavation are found) → reaming bit installation platform construction → reaming bit lifting → reaming bit installation → installation platform withdrawal → reaming bit removal → reaming bit removal → reaming bit removal → reverse well drilling rig removal.
