Product Description:

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


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.


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: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?
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. It extends in the first order, the next second, and then the third, the last, the fourth, and the fifth. During drilling, it is stretched by gravity and bit by bit with the drilling depth. Rotary drilling rig in the multi-functional areas to improve, and it is not necessary to complex conversion can be converted to another device, it is worth studying.
Q:How long is the auger type 360?
The thickness of each drill string is controlled sequentially. Extend from coarse to fine. Retract from thin to thick.
Q:What are the hidden dangers during the construction stage of rotary drilling rig?
A rotary drill is used in the high water level areas or Plains. The soil is clay, water silt, silty soil, artificial backfill and gravel, gravel stratum containing part. The digging process is the basic soil mud rushed out, not every time to pull the bit put out the soil, it is necessary to use mud, but this wall is very fragile, whether it is empty or keep drilling, hole inside and outside of the head, the water is too high to slurry leakage and hole collapse, the water level is too low will be water seepage hole collapse into the hole. But the speed is very fast.
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:XCMG XR360 rotary drilling rig generally how much?
The reasonable price is based on your own, do you do it yourself? Where are you from and where is the project?
Q:What is a rotary pile?
In China, it is an advanced pile foundation construction technology, which is widely used in recent years. It is widely used in highway, railway, bridge and large building foundation pile construction. In the early days, most of the rotary drilling rigs were imported from Germany and Italy, or Japanese second-hand rotary drilling rigs. In recent years, with the Qinghai Tibet railway, Beijing bird's nest and other projects to promote the influx of foreign brands, China's similar products are gradually developed.
Q:What is the minimum drilling diameter of the Sany SR150C rotary drilling rig?
Sany, founded in 1994 by the 31 group, Limited by Share Ltd, has broken through the traditional "phobia" of the Chinese people, and has stood up to the rapid rise of independent innovation. In July 3, 2003, Sany listed on the A shares (Stock Code: 600031); July 2011, Sany to $21 billion 584 million in market capitalization topped the British "Financial Times" the world's top 500, is so far the only list of China machinery enterprises; in January 2012, Sany acquired the "first world brand" concrete Putzmeister Germany (Putzmeister), changed the global competition pattern
Q:Which rotary drilling rig is durable and economical?
With FR622D FR620D, leiwo, comfortable operation, strong ability in rock.
Q:What kind of geology is a rotary drill suitable for?
Wet (or bucket) and rock (core drill hole), with a large installed power, large output torque, axial pressure, flexible rotary drilling rig, high construction efficiency and function characteristics. To adapt to the soil geological conditions in most parts of the rotary drilling rig, with a wide range of basic can meet the needs of bridge construction, the use of high-rise building foundation engineering. At present, has been widely applied to all kinds of construction of bored pile drilling rig.
Q:The rotary drilling drill bit rock weathering by what
The rotary drilling drilling in weathered rock weathering, according to the hardness of the rock to determine what bit.Stainless steel drills are generally used. Especially hard cases with diamond or graphite steel drills.
