Two monitoring well operational procedures
The well location measuring well point of offer → → rig install in place → → mud (addition yellow mud) hole encircle and hunt down → → drilling well extremely
Projected depth → → well casing (because well casing is four sections, therefore this procedure needs a section well casing connection is gone into the well) is installed and hung down
Directly → → correction well casing (keeps well casing to be located at the center of well, the mode of correction each drilling company should difference, this Shen
Please with to be fixation with steel wire correct, it is convenient succinct) → → throw in filtrate (filtrate Φ 5-15 ㎜ gravels) → → cleaning well
Mud → → examination draws water → → positive examination draw water (either for monitoring or domestic water, be required for drawing water, on the one hand can be by
The yellow mud on unnecessary silt and the borehole wall in well is developed, well water is evacuated in formal drawing water on the other hand it is limpid, so as to
Monitor and use).
Well location is determined by your unit according to integrated planning drilling well position in region.
3. after rig is installed in place, well location is checked, after confirmation is errorless, by hand excavation's Φ 700mm circular hole cutting depths
500mm, buried Φ 700mm wall protection pipes (pillar wall be exactly in order to drilling process protect well head, aided drilling and prevent periphery soil
Block is collapsed), wall protection pipe is buried after finishing, and rig hangs in Φ 700mm wall protection pipes Φ 600mm " one " font drill bit, and will be viscous
Property native (yellow mud) while being put into the hole in and then clear water being filled in hole and start percussion drilling, drilling process is always using high density mud
