Rotary drilling rig is a kind of construction machinery suitable for hole forming in construction foundation engineering. It is widely used in municipal construction, highway bridges, high-rise buildings and other basic construction projects. With different drilling tools, it is suitable for dry (short screw), or wet (rotary bucket) and rock formation (core drilling).
Rotary drilling rigs are mainly used to form holes for foundation foundation piles. The drill bits have various forms: such as rotary buckets, short spirals, core drill bits, etc. According to different geological conditions, different drill bits are replaced to achieve high speed and high quality. hole forming requirements.
The rotary drilling rig has the characteristics of large installed power, large output torque, large axial pressure, flexible maneuverability, high construction efficiency and multi-function. The rotary drilling rig is suitable for the soil geological conditions in most areas of our country, and has a wide range of use, which can basically meet the use of bridge construction, high-rise building foundation and other projects. At present, rotary excavators have been widely used in various bored pile projects.
Rotary drilling rig has become the main hole-forming equipment for bored pile construction due to its advantages of fast construction speed, good hole-forming quality, low environmental pollution, flexible and convenient operation, high safety performance and strong applicability. In order to ensure the progress and quality of the project, the owner used it as the designated construction equipment, thus replacing the traditional percussion and rotary drilling rig hole-forming equipment.
