MGJ-50L Crawler Drill Rig for Anchoring andJet-grouting

Applications：

MGJ-50L crawler drill rig for anchoringand jet-grouting is a type of integration of crawler, mud pump and controlpanel based on original MGJ-50 drill rig for anchoring and jet-grouting. Itfeatures long feed stroke, large capacity, easy to operate and move etc. It isbetter idea anchoring drill rig for anchoring bar, consolidating andstrengthening engineering and all other engineering geological drilling.Thedrilling rig is mainly used in soil and rock anchoring, consolidation of roadbase, dam base and retaining wall, and blasting hole drilling and jet-grouting.

MAIN SPECIFICATIONS：

1. The drill rig is withmechanical transmission and hydraulic feed, drill hole dia. is mainly110—130mm(can reach 180mm), drilling capacity 60 m, can drill at any anglebetween horizontal and vertical.

2. Long feeding stroke reaching2300 mm with 2 m drill rod.

3. Using with rotation drillingand percussion –rotation drilling, drill efficiently.

4. Support cylinder, it is easyto adjust the angle of the mast.

5. With crawler, it is easy andfast to find out the drill hole position.

Q: Construction steps of rotary drilling rig: The rotary drilling machine is in place and burying the protecting cylinder! When the bit is filled with soil sand material, the outer hole and the rotary drilling rig will be lifted

Q: What's the price of the 31 sr630rc8 rotary drilling rig?: 31 drilling rigs are good in domestic brands.

Q: Xr220a rotary drilling machine drilling 2 meters hole can reach 80 meters, its maximum drilling depth is 80 meters, the maximum aperture is 2 meters.: Attention is conditional, and there is the maximum drilling depth is 79 meters, there are 1 meters gap, if you count the drill bucket distance, barely enough.

Q: What is the market prospect of rotary drilling rig?: Market awareness increased rapidly, and the market capacity expanded rapidly. Rising market demand attracted into the domestic large-scale engineering machinery enterprises, Hunan Yu Tai heavy production of small rotarydiggingmachine relatively affordable price

Q: How long is the auger type 360?: The drill rod of the rotary drilling machine is now extended from the lower part of the hoist, the steel wire extends out, and the hoisting rope is retracted. But some rotary drills can be extended either by a crane or by gravity.

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.

Q: How many litres of oil are usually consumed per hour in a rotary drilling rig?: This is not sure, depends on what type, and when the work is not full power work. +1And you work with the stratum is related, as far as I know, the intelligent drilling machine is still more fuel-efficient, 31, Zhonglian is also good

Q: I love inventing super rotary drilling rigs. Can they dig wells? Can they move rocks? How deep can they hit?: Because now the double power head drill wells with rotary drill rod is rotary drill, but few are more than 2 meters in diameter with direct rock itself, very fast, low cost of the machine drill many times than rotary drilling. I suggest you check the pile hole drill on the Internet, or the China Sea Hengtong, it is easy to find information.

Q: What are the polymer slurries used for rotary drilling machines?: The polymer mud of rotary drilling rig is a kind of organic macromolecule material which is made up of anti collapse material, sediment treatment material and anti leakage agent. The earliest producers of polymer mud in China are CIS and Chennai, both of which are imported. The price is much higher than that of bentonite, and the dosage is much smaller

Q: The overall structure and working principle of rotary excavation?: The auger drills, such as short auger bit, ordinary drill bit, sand drill bit, core and so on, can be drilled into different layers of clay, gravel, pebble and medium weathered mudstone.
