GK 200 Engineering Drilling Rig Advantages

It has hydraulic feeding structure, drilling efficiency and reduce workers' labor intensity. The drilling rig is equipped with upper ball clamp clamping mechanism and hexagonal active drill pipe, which can reverse the rod without stopping, with high working efficiency, convenient and reliable operation. It is equipped with a hole bottom pressure gauge to indicate the pressure, which is convenient to master the situation in the hole.The handle is centralized and easy to operate.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.

GK 200 Engineering Drilling Rig Application

1.Construction drilling of the projects e.g. prospection, geotechnical investigation, railway, road, port, bridge, water conservancy and hydropower, tunnel, well, industrial and civil construction;
2. Coal mining exploration, Ore exploration;
3. Small hole diameter water well drilling;
4. Geothermal pipe-installing for heat pump;
5. Small-diameter hole foundation piling drilling

Installing Core Tube Method

Buckle the lifter into the groove of the variable diameter joint, move the right handle of the winch to take the pad fork, take out the perforated pipe, install the core tube, lift the drilling tool to the top of the borehole, move the left handle of the winch continuously, and lower the drilling tool into the borehole at a uniform speed. When the groove of the variable diameter joint is close to the inlet, use the pad fork to block and remove the lifter.

Core tube - coring tool

1. Single layer core pipe

The single pipe drilling tool has simple structure and convenient processing. It is a common coring tool for hard alloy and steel particle drilling. The flushing liquid in the single pipe drilling tool is sent into the core pipe by the drill pipe. The drill accessories that directly rush to the top of the core, and the impact and friction of the core caused by the rotation of the core pipe, are very easy to wear and tear the core, so they are only applicable to relatively complete and stable formations.

2. Double core tube

The double-layer core pipe is formed by adding a core containing pipe (inner pipe) to the original core pipe (outer pipe). According to whether the inner pipe rotates during drilling, it can be divided into two types: double acting and single acting:

Double layer double acting core tube (double acting double tube) - the outer tube rotates and the inner tube also rotates.

Double layer single acting core tube (single acting double tube) - the outer tube rotates but the inner tube does not rotate.

The double-layer core pipe can isolate the scouring effect of the washing liquid on the core. Double acting double pipe water isolation without vibration isolation, used for soft, loose and easily eroded formations; The single acting double pipe can isolate water and vibration, and the scope of application is more extensive. Basically, the drill accessories of single acting double pipe drill are used for diamond drilling.
