The impact of groundwater and countermeasures during the construction of sand and gravel layer water well drilling RIGS

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.

  1. Adjust mud performance based on groundwater level and quality to enhance impermeability and erosion resistance.
  2. If groundwater is abundant, set up water collection wells to drain it promptly and lower the water level.
  3. Strengthen monitoring of groundwater dynamics during construction to ensure safe and smooth progress.water well drilling rig
