Soft soil layers often
contain abundant groundwater, whose flow and pressure changes cause construction difficulties like borehole collapse and sand gushing.water well drilling rig
To control groundwater, here are key methods:

-
Dewatering Well Method:
- Arrange dewatering wells around the construction area to lower the groundwater level.
- Monitor settlements of surrounding buildings and ground during dewatering to avoid collapse.
-
Waterstop Curtain Technology:
- Form a continuous waterstop wall via high-pressure jet grouting or deep mixing.
- This blocks groundwater flow around the construction site effectively.
-
Adjust Construction Parameters:
- Modify mud properties and drilling parameters based on groundwater conditions.
- This ensures safe and smooth drilling by adapting to groundwater dynamics.water well drilling rig
