GK 200 Geological Drilling Rig Advantages
1) It has a hydraulic feeding structure to improve the drilling
efficiency and reduce the labor intensity of workers.
(2) The drilling rig is equipped with upper ball clamp clamping
mechanism and hexagonal active drill pipe, which can reverse the
rod without shutdown and is easy to operate.
(3) It is equipped with a hole bottom pressure gauge to indicate
the pressure, which is convenient to master the situation in the
hole.
(4) The handle is centralized and easy to operate.
(5) The base is equipped with an oil cylinder, which can move back
and forth for easy lifting and lowering of drilling tools
(6) The drilling rig has the advantages of compact structure, small
volume, light weight, strong decomposition and easy relocation. The
loading form is trailer type, crawler type and disassembly. It is
suitable for working in plain or mountainous areas.
Precautions for courtyard drilling
1. Consider whether the well depth is reasonable
We should first investigate whether there are cables, sewers and
other facilities under the ground, and avoid unnecessary damage.
2. Convenience, health and other issues should be considered.
After drilling the well, find some charcoal and throw it into the
well with a bag and press it at the bottom of the well to absorb
foreign toxins. After having water, you can put a few small fish
down, which is a good way to test the safety of water quality.
3. The well should not be too deep. It should be above the ground
and should be blocked with bricks and stones. It is better to have
a cover, so as to prevent dirt from falling in, make people feel
safer and avoid unnecessary dangers.
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
.
