What kind of geology is a rotary drill suitable for?
Rotary drilling can be used in all geological conditions, but only in accordance with specific geological conditions, to take appropriate construction methods drilling tools
Wet (or bucket) and rock (core drill hole), with a large installed power, large output torque, axial pressure, flexible rotary drilling rig, high construction efficiency and function characteristics. To adapt to the soil geological conditions in most parts of the rotary drilling rig, with a wide range of basic can meet the needs of bridge construction, the use of high-rise building foundation engineering. At present, has been widely applied to all kinds of construction of bored pile drilling rig.
Is a rotary drill hole construction process operation for building foundation engineering. Widely used in construction engineering to municipal infrastructure construction, highway bridges and high-rise buildings, with different tools, suitable for dry (short spiral),
