GK 200 Core Drilling Rig Product Advantages
Diamond drill bit,alloy drill bit and steel roller drill bit and so on are available for drilling according to different geological structure.
When the final hole are respectively 75mm and 46mm in diameter, the rated hole depths are 100m and 180m.The max of depth may not exceed 110% of that drilled in each hole. The max allowable hole diameter is 150mm
With the hydraulic feeding mechanism,improve the drilling efficiency,reducing the labor intensity of workers.
The drilling machine has the advantages of compact structure,small volume,light weight,convenient move,decomposition and strong,suitable for the plains or mountain areas.Adopting large Kelly,double guide pipe. Increase the stability .
GK 200 Core Drilling Rig Drilling Rig Applications
1. The drilling rig hydraulic transmission of the rig effectively utilizes the power. This makes the overall power loss small and the drilling cost low.
2. The drill rig has more positive speed stages and 14-500r / min speed range, and the output torque is 13428-250N.m.3. The drilling rig has 2 reverse speeds, which is convenient for handling accidents.4. The air compressor drilling rig adopts a long-stroke double-speed mechanism, a mechanical power head, and a power head stroke of 3400MM to improve drilling efficiency and reduce the occurrence of plugging and burning accidents.5. The water well drilling rig rig uses dual oil pumps for oil supply. A single pump is used for drilling, and a double pump is used for confluence when lifting. The power loss is small and the auxiliary time is short.6. The drilling rig machine has advanced structure and reasonable layout, which is convenient for maintenance, maintenance and repair.7. The crawler water drilling rig machine chassis is adopted, and the trip of the outrigger
cylinder can be automatically loaded for 1.5m, which is convenient for relocation and transportation.8. The drill rig reserves some functional interfaces in the hydraulic system, and can expand the functions according to the technological requirements of different users.
Soil Sampling Procedure
Divide the field into different homogeneous units based on the visual observation and farmer's experience.
Remove the surface litter at the sampling spot.
Drive the auger to a plough depth of 15 cm and draw the soil sample.
Collect at least 10 to 15 samples from each sampling unit and place in a bucket or tray.
If auger is not available, make a 'V' shaped cut to a depth of 15 cm in the sampling spot using spade.
Remove thick slices of soil from top to bottom of exposed face of the 'V' shaped cut and place in a clean container.
