Spot welding and arc striking on the spiral drill pipe are prohibited for the maintenance of the spiral drill pipe. After using the long spiral drill pipe to drill a shallow hole for a period of time, the spiral drill pipe should be pulled apart to clean up the sediment between the spiral drill pipes. After the burying accident, the gravel sand between the spiral drill pipes must be cleaned. After drilling in the more viscous mud, the auger pipe must be cleaned.
