What kinds of common drilling rigs are there?
Core Drilling Rig
core drilling rig is suitable for large and small diameter core drilling mainly based on alloy stone and diamond. It is suitable for metal and non-metal solid mineral deposit exploration, shallow oil and natural gas exploration, geothermal well exploration, mine tunnel ventilation, drainage and In the construction of large-diameter foundation piles, concrete core drilling machines are widely used in geology, metallurgy, coal, hydrology, water wells, engineering and other fields.
Water Well Drilling Rigs
A water well drilling machine is a mechanical equipment for drilling water wells and completing operations such as downhole pipes and well washing. Generally, it is divided into three categories: rotary rotary machine, percussion drilling machine and compound rotary machine. Water well drilling rigs can be divided into bulk type, trailer type and vehicle-mounted type, and crawler type according to the assembly form; according to the drilling depth, they are divided into shallow well drilling rigs, medium-deep well drilling rigs, deep well drilling rigs, and ultra-deep well drilling rigs; according to the type of driving equipment It can be divided into mechanical drive drilling rigs, electric drive drilling rigs, and hydraulic drilling rigs.
Down the Hole Drilling
Down the Hole Drilling can drill holes in rocks of medium hard or above (f≥8). Like the rock drill, it has the process of rock drilling and hole formation of impact, rotation, ballast removal and advancement, and both belong to the impact rotary drilling. Like the external rotary rock drill, it has an independent slewing mechanism and an impact mechanism. The difference is that the impact mechanism of the DTH drilling rig is installed at the front end of the drill pipe, submerged into the bottom of the hole, and continuously advances with the extension of the drilling. DTH drilling rig is named after the impactor dives into the bottom of the hole.
Rotary Drilling Rig
Rotary drilling rig is a construction machine suitable for drilling operations in building foundation engineering. Widely used in municipal construction, highway bridges, high-rise buildings and other foundation construction projects, with different drilling tools, suitable for dry (short spiral), or wet (rotary bucket) and rock (core drilling) drilling operations, rotary drilling machine has the characteristics of large installed power, large output torque, large axial pressure, flexibility, high construction efficiency and multi-function.
Anchor Drilling Machine
Anchor drilling machine, also known as bolt drilling rig, is a pneumatic impact machine. The anchor drilling machine is mainly used in landslides and dangerous rock mass anchoring projects in the prevention and control of various geological disasters. It is suitable for the construction of urban deep foundation pits and anti-floating anchors. For pole and foundation grouting reinforcement engineering holes, blasting holes for blasting engineering, high-pressure jet grouting piles, tunnel pipe shed support holes, etc., the power head can be slightly changed to facilitate all-round construction. Anchor drilling rig is suitable for a variety of drilling processes. The output speed of the power head is continuously variable. The drilling parameters can be independently selected according to different construction requirements and geological conditions to achieve the best drilling efficiency.
