GK 200 Core Drilling Rig Advantages
With the hydraulic feeding mechanism,improve the drilling efficiency,reducing the labor intensity of workers.
The rig is equipped with a ball on a cassette holding mechanism and a six side rod, the rod can be replaced without shutdown, high work efficiency, safe and reliable
Furnished with hole bottom pressure gauge pressure indicator,and easy to master the status inside the hole
The handle centered, convenient operation.
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 .
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.
