In gravel layers, abundant and fast-flowing
groundwater significantly affects well construction, prone to causing hole wall instability and mud performance deterioration.water well drilling rig
To address groundwater impact, adopt water-stop curtain technology. Form a continuous water-stop wall around the construction area via high-pressure jet grouting or deep mixing to block groundwater flow.
- Adjust mud performance based on groundwater level and quality to enhance impermeability and erosion resistance.
- If groundwater is abundant, set up water collection wells to drain it promptly and lower the water level.
- Strengthen monitoring of groundwater dynamics during construction to ensure safe and smooth progress.water well drilling rig
