150 Meters Depth Exploration Drill Rig Construction Core Engineering
150 Meters Detph Construction Core Engineering Drilling Rig Machinery
XY-1A Engineering Drilling Rig Self Introduction
This is a kind of widely used portable drill machine. It is suitable for drilling water well,geological survey, geological core drilling, small grouting holes, blasting holes of railway, water conservancy, bridges, dam foundation and other buildings. According to different strata, it drills by choosing different bits, such as, diamond composite films and alloy.

XY-1A Engineering Drilling Rig Main Advantage
1 The oil pressure feeding mechanism can improve drilling efficiency and reduce the labor intensity.
2 The drilling rig is equipped with a ball mounted card blessing mechanism with six side active drill rods and falling rod.
And it has the advantages of high work efficiency, convenient operation, safety and reliability.
3 Hole pressure gauge indicates pressure which can be easy to grasp the situation inside the hole.
4 Handle concentration, easy operation.
The principle of core drilling machine
The principle of core drilling machine is basically the same, and the main components are drilling machine, drill pipe, drill bit, etc. The drill provides power to drive the drill pipe and drill bit to drill and obtain deep core samples. According to different depths and strata, corresponding to different types of drilling rigs
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.
