GK 200 Borehole Drilling Rig Advantages
1.Engine:Feed by hydraulic cylinder,the drilling efficiency is higher and it can save labor.
2.Drill rod:53x59 drilling rod adopted,high rigidity and strong delivery torque.
3.Spindle:Vertical spindle are fixed by four groups of bearing to ensure that the rotary machine is rigid enough for gravel layer and other complex geoloical conditions.
4.Mud pump:Equip mud pump with flow 160L/min,save cost and also make the structure compact.
5.Concentrated handle, small footprint,light weight, strong decomposition, easy to move.
Does a deeper wells mean better water?
In general, when it comes to water quality and well depth, there's one golden rule: the deeper the well, the better the water quality. As you go deeper down, there's a higher chance that the water you encounter will be rich in minerals
Construction Technology of de watering well
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.
