150m SPT Diamond Core Hydraulic Borehole Drilling Rig Machine
Description of water well drilling machine:
In the steering and braking structure, single axle steering brake replaces the original the double axle gear brake, which greatly reduces the attrition degree of wear parts.
Using wet friction brake is more reliable. The hydraulic transmission tower lifting device is safe and convenient to go up and down and easy to move the whole operation.
Also it can be modified according to the customer's reasonable requirements.

Advantages:
1 The four feet are hydraulic support legs. Each one is controlled alone which make the platform is fixed on the ground smoothly.
2 The maximum load of the platform is 4500kg and can load XY-2 drilling rig furthest. The size of the platform is reasonable.
3 The chassis adopts rubber track, which has the advantages of lighter weight, lower life-cycle costs, and less vehicle running gear noise, less vehicle vibration, less fuel consumption. It does not hurt the pavement in the city roads.
Why is the water well drill 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 deep drawdown pumping can be done. The water level stability lasts for at least eight hours. At the same time, the water flow at the dynamic water level of the well is measured. The well drilling works shall ensure smooth drainage of the construction site, so the rainy season shall be avoided. During excavation, the excavation slope shall be determined according to the physical and mechanical properties of the soil layer, generally 1:1.5. There shall be a certain distance between the toe of the spoil slope and the upper opening of the excavation. For large well with water inlet in the shaft wall, the inlet hole and inverted filter of the shaft wall must be arranged according to the design requirements, and the inlet hole shall be prevented from blocking during construction. The filter material enclosure at the aquifer shall meet the requirements. The backfill shall have a certain superelevation. The frozen soil in the backfill in winter shall not exceed 15%.
