Rotary drilling is a construction technology suitable for hole-forming operations in building foundation engineering. It is widely used in municipal construction, highway bridges, high-rise buildings and other foundation construction projects. With different drilling tools, it is suitable for dry (short spiral) or wet (revolving bucket) and rock (core drilling) drilling operations.
