What is the essential difference between rotary drilling rig and rotary drilling rig?
English is rotary drilling rotary drill rig, in addition to the configuration of various rotary bucket operation, installation of casing drilling, with rolling tube device and grab for will casing construction; with telescopic guide rod grab underground continuous wall construction, with DTH of hard rock crushing construction; operation device can also be replaced for jet construction and circulation of construction; construction of pile foundation can also configure other forms of hydraulic hammer, diesel hammer etc..
Cyclotron is used drilling mud circulation way out of the mud, in the form of power head of rotary drilling, using powerful torque directly to the soil or gravel and other rotary drilling waste slag mining, and then use the spin bucket hole is put forward quickly out of dry soil.
Rotary drilling rig is a kind of construction machine suitable for drilling operation in building foundation engineering. Mainly suitable for sand, clay, silty soil layer construction, bored pile, continuous wall, foundation reinforcement has been widely used in various foundation foundation construction, the rated power of rotary drilling rig is 125 ~ 450kW, the power output torque of 120 ~ 400kN / m, the maximum diameter of Kong Zhi is 1.5 to 4m. The maximum hole depth is 60 ~ 90m, can meet the requirements of all kinds of large-scale infrastructure construction.
