Description

Technical Field

[0001] The utility model relates to the technical field of drilling equipment, in particular to a drilling device for construction engineering survey. Background Art

[0002] Construction sites usually require drilling surveys before construction. This helps determine underground conditions, including geological structures, groundwater levels, soil types, etc. This information is crucial for design and construction.
