Application scope of rotary drilling rig construction?

Rotary drilling rig is a kind of construction machinery which is suitable for hole forming operation in building foundation engineering. It is widely used in municipal construction, highway bridge, high-rise building and other foundation construction projects. With different drilling tools, it is suitable for dry (short screw), wet (rotary bucket) and rock (core drill) hole forming operation. Rotary drilling rig has large installed power, large output torque and large axial pressure It is characterized by flexibility, high construction efficiency and multi-function. The rotary drilling rig adapts to the soil geological conditions in most areas of our country and has a wide range of application. It can basically meet the needs of bridge construction, high-rise building foundation and other projects. At present, the rotary drilling rig has been widely used in various bored pile projects. Therefore, it is of great significance to discuss the construction preparation of rotary drilling rig and common clean water construction technology.
