Q:Rotary drilling rig how telescopic, I mean, what power so that it extends out of step by level, it extends out in a certain order?
Friction compression drill rod (abbreviation: friction rod, friction drill rod)It is generally used for drilling in soft formation, which can be used for drilling mud, soil, sand and egg (drift). The friction drill rod is usually made up of 5 sections, each of which is 13 meters long and 1~4 times longer than each steel tube. Drilling depth of about 60 meters.
Q:What are the reasons for partial drilling of rotary drilling machine?
Drilling bucket: the main function of drilling bucket is cutting and drilling, but it also has the function of guiding and preventing deviation. The pilot base drilling bucket with positioning function, at the same time the pilot pointed tip can be changed into order, and the number of teeth of the drill view is not common, the drill body on both sides of the knife or door bar height is not common, these details can make drilling bucket drilling about uniform stress and prevent error.
Q:The structure and principle of hydraulic rotary drilling rig are discussed!
Hydraulic and electrical should be explained on the spot. It's not good to explain to youConclusion: to know the hydraulic rotary drill movements, each action is respectively connected with the two pipes into one, you can get ahead from, the following are some pilot valve block and control the small tube, you can find the back from the cab, find the valve block. Look, where are the controls? Don't see so many pipes.Electrical is also very simple, the electrical cabinet is the core, but also divided into several blocks, divided into several major areas, the decomposition of control on the line.
Q:What is the minimum diameter of a bored pile?
The minimum diameter of the bored pile is 310 mm;
Q:What is the drilling speed of rotary drilling machine?
This is related to construction, formation and pressure. You cannot set the constant penetration rate.
Q:Rotary drilling rig on the floor under the floor with steps
Back on the truck, slowly, especially when the center of gravity. In short, pay more attention to it! Before loading, the machine must be adjusted to the state of transport, on the trailer when the spiral digging back up, down the trailer when it is good, straight down. Obey the command, careful driving, generally no accident.
Q:How heavy is the 250 auger rig?
250 rotary excavation, weighing about 70-80 tons
Q:Can rotary drilling machine be used in rock layer?
The rock layer depends on the hardness, I have seen the 280 rig called 700KPA mudstone and 2200KPA granite, and 250 rigs played 4000KPA to beat rock schist, the key lies in the construction of rotary drilling rig, a rock speed is very slow.
Q:Can the rotary drilling rig of fine round gravel soil move?
Gravelly soil is an unconsolidated or argillaceous cemented soil with a particle size of not less than 50% of the total mass of 20mm.
Q:For different geological conditions, how to choose rotary drilling, rotary drilling, impact drilling?
Such a soil condition, it is not recommended to use rotary drilling rig. The upper soil can be drilled with a rotary drill, and an impact drill can be used after the formation of rock.
