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: The principle diagram of operating system rotarydiggingmachine: At the same time to drill pipe and drill through the pressurized cylinder head transfer pressure, pressure to achieve drilling bit, when filled with muck, the main hoist bit left rotary drilling, host to a certain point of view, open the bit bottom door, everywhere on the muck, Doumen, back drilling locations, decentralization of drill pipe, the drill into the hole again in drilling.

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: What's the minimum cost of a rotary drill? How much is it?: Sunward rotary drilling rig 22 models and 25 models of new machines, 22 of the 5 million or so. 25 will be around 6 million, depending on your choice of accessories

Q: What is the difference between punched pile and rotary pile?: Rotary pile generally refers to the pile type constructed by rotary drilling rig. It is called full blown bored pile, which is called rotary pile for short. Due to the use of mechanical work, the number of workers is not high, it can save a lot of labor costs

Q: The rotary drilling drill bit rock weathering by what: 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.

Q: 31 What about the performance of the auger rig?: The appearance and configuration with the domestic and foreign similar equipment, the overall performance of the domestic first-line manufacturers of equipment are similar, slightly higher than the overall performance of foreign equipment.

Q: What brand is the best for rotary drilling machine?: But domestic drilling rigs have high performance price ratio. In the late use, equipment will inevitably fail, and domestic brands of timely service is good.

Q: What are the differences and relations between machine, trenchless drilling rig, horizontal directional drilling machine and rotary drilling rig?,: The rotary drilling machine seems to be laying foundations for example when building a house, digging a hole with a rotary drilling machine and pouring it into the concrete.

Q: How many meters of construction hole pile can be used for a selection of tile drill from input to scrap, whether it is related to the diameter of hole pile: Domestic rotary drilling rig under normal maintenance, the use of more than 6 years, almost or even longer. The imported equipment maintenance normal use, I feel more than two decades is not a big problem. However, this does not include the production plant equipment production design of abnormal special circumstances and construction operation is not correct, and accidents.

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.
