GK200 Water Well Drilling Rig Engineering Machinery Without Air Compressor
Geological Drilling Rig Machine brief introduction
The GK-200 mobile drilling rig is a kind of widely used and hydraulic feeding drill, which has the characteristics of big power, great lifting force (2T) and high transmission torque. It can be used in engineering geological survey of railway, hydropower, transportation, bridge, foundation and other buildings, geological core drilling and physical exploration and so on.

How about the features of it ?
1. With hydraulic automaatic feeding device, elevated drilling efficiency.
2. Large torque and drilling diameter.
3. With a spherial jaw holding mechanism and the rod replacement without breakdwn, high efficiency.
4. Compact structure, small volume, lightweight, high detachability, easy transportation and suitable for the operations in plains or mountain areas.
5. Adoping large drive pipe, double guide rod, increase the stability.
Well point measurement and positioning → hole digging and casing embedding → drilling rig in place → drilling → hoisting well pipe → back-filling filter material (coarse sand or gravel) between well pipe and hole wall → hole washing → drainage pump in well pipe and installation of pumping control circuit → trial pumping → normal operation of well point → de watering completion, pipe pulling → well sealing.
The de watering shall be carried out 20 days before the excavation of the foundation pit, so as to drain the stagnant water in the stratum in advance, reduce the groundwater level, improve the self stabilization capacity of the soil layer, and smoothly carry out the anhydrous operation. During the de watering operation, the water level observation of each well shall be done well, and the change of the head of the confined aquifer shall be mastered in time
