GK 200 Soil Testing Drilling Machine Advantages
1. Adopt Low speed high torque hydraulic motor drive rotary device output torque
2. The advantage of cylinder is promoting more stable, less failure significantly than the motor propulsion.
3. Equip two filter effectively to ensure the safety of diesel engine intake and prolong engine life.
4. It can readily monitor rig hydraulic system pressure and boost pressure to ensure the rig stable and efficient operation.
5.Using well-known brands of multi-way control valve, superior performance, handle centralized, easy to operate
Why is the the drilling rig not suitable for use in rainy days?
After the well is completed, it is necessary to pump water to check the results. Under normal circumstances, a large drawdown pumping can be done. The stable duration of the water level shall not be less than eight hours, and the water flow of the dynamic water level of the well shall be measured at the same time. The well drilling project shall ensure the smooth drainage of the construction site, so the rainy season shall be avoided. When working while excavating, the excavation slope shall be determined according to the physical and mechanical properties of the soil layer, generally 1:1.5, and there shall be a certain distance from the toe of the spoil slope to the upper opening of the excavation. For large wells with water inflow from the shaft wall, the water inlet hole and inverted filter layer of the shaft wall must be arranged according to the design requirements, and the water inlet hole shall be prevented from being blocked during construction. The filter material enclosure at the aquifer shall meet the requirements, the backfill shall have a certain superelevation, and the frozen soil in the backfill in winter shall not exceed 15%.
