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:What's the difference between the main oil pump imported from the rotary drilling rig and the home made main pump?: The rotary drilling rig has two winches, one main hoist and one auxiliary winding, wherein the auxiliary winding is of some auxiliary function, such as hanging a protecting cylinder or something, and the main hoist is used for lifting the drill pipe.

Q:What is the minimum diameter of a bored pile?: The minimum diameter of the rotary bored pile is 670mm, the drill bit diameter is 600mm, and the actual drilling hole is 670mm.

Q:What are the components of rotary drilling rig Jixietaiban? How to calculate?: This contract according to the geology and site conditions have different changes, according to a 24 hour standard, a drill, a crane, a forklift, each driver two, a site manager, coolie four, perfusion six, a welder, purchasing a drill, water pump and other auxiliary vessel some general tools, according to the size of pile, geological conditions of pricing, how much money per meter.

Q:Kim Taixuan drilling operations and other brands of rotary drilling operation do.: Kim said the truth than other manufacturers of machine operation is relatively simple, because the machine is Kim hydromechatronics, many other manufacturers to operate the machines are easy, and the construction efficiency is relatively high in similar products.

Q:Wylong machinery rotary drilling rig in the use of the external power? How many volts does it take to drive?: The rotary pile driver is usually a spiral rod with diesel oil, and the pile driving machine has dual purposes of firewood and electricity

Q:Hole drilling price of rotary drilling machine: Strong weathered formations are often encountered in the Sichuan area, and drilling is not difficult for the Xugong rotary drilling rig! Please consider these questions more!

Q:What is a rotary cast in place pile?: Rotary drilling rig is the first barrel type rotary drill through the bottom valve with broken rock and soil, and directly in the drilling bucket, and then by the rig hoisting device and drill rod of the drilling bucket dumping hole is proposed, so the cycle, constantly borrow dump, until the drill to the design depth.

Q:How should we deal with the abnormal encountered during the construction of rotary drilling and drilling?: When the hole is not serious, the drilling can be continued by adopting the measures of increasing the specific gravity of the mud, heightening the water head and burying the deep protecting cylinder. When the hole is serious, the backfill will be drilled again.When drilling and bending holes occur in the drilling hole, the drill bit of the rotary drill can be raised to the inclined position for repeated hole sweeping until the drilling is upright. In the event of serious bending hole, plum blossom hole, probe stone, the small stone or gravel and clay mixture backfill to deflection, to be heavy filler after re drilling deviation.When drilling, it is not strong lifting. The cause and location of the bit shall be ascertained, and large ropes shall be moved, small bit impact shall be taken, and other measures taken to make the drill loose and brought up.

Q:Rotarydiggingmachine operating permit test how: Rotarydiggingmachine also called rotary drilling rig. The utility model is a tool for road traffic and high-rise building construction. The rotary drilling rig is a kind of comprehensive, it can use the short helix bit dry digging, can also be used in wet digging rotary drill mud case. Rotarydiggingmachine with hammer drill hole digging work pieces after hard formation. If the enlarged head drilling tool is used, the reaming operation can be carried out at the bottom of the hole. Rotary digging machine adopts multi-layer telescopic auxiliary drilling drill pipe, less time, low labor intensity, without mud circulation deslagging, cost saving, no pollution, infrastructure construction is especially suitable for the construction of the city.

Q:Is the rig operator tired?: Small size, light weight, easy operation and convenient maintenance. Gear type pneumatic motor with stable operation and high reliability. The design of a new type of glass reinforced plastic air leg is of high reliability and long service life.
