GK 200 Portable Hydraulic Crawler Mounted Drilling Rig With 8 Wheels Folding Tower For Water And Exploration
GK 200 Portable Water Well Drilling Rig Introduction
It has the features of big turning torque and big opening diameter. And it is compact, small in size, light in weight, strong in decomposition and easy to remove . This drilling machine adopts big driven drill pipe and double guide rod to increase stability .This rig can move 350mm back and forth on the base, so it facilitates the removal of the drill pipe.

GK 200 Drilling Rig Application
1 The rig is suitable for survey and prospecting, geophysical exploration, roads and buildings and other exploration and play blasthole drilling bits projects.
2 Drilling bits can be chosen according to different strata .
3. Suitable for the 2-9 grade sandy clay and bedrock.
4 Rated drilling depth 100m, the deepest can not exceed 120m. Nominal hole diameter of 110mm, the maximum opening straight Diameter allowed to be 130mm, the final hole diameter of 75mm, drilling depth according to ground conditions.
Five experiences in finding water from large wells in Qingshi Mountain area:
1, The groundwater level of thick limestone is generally deep, and when the water level is shallow, fractured zones and fault zones can be found.
2, Thick marl is generally not easy to drill a well, and a well with good water volume can be found when the supply conditions are good due to severe weathering and fragmentation.
3, The dolomitic gray layer is better in areas with longer seasonal spring periods and is generally not easy to drill wells.
4, When the supply conditions of limestone mixed with shale are very certain, the conditions are better.
5, In general, in the case of engineering drilling rigs, the water level in the limestone formation is not high enough to reach the area, which means that there is generally not enough water pump to continuously pump water.
