2. Then dig a small pit with inclined shaft wall at the wellhead, set up a drilling rig in the pit and drill through a series of drilling tools.
3. According to the drilling data and geological conditions, arrange the position, depth and quantity of blasting holes to increase the water output.
4. After the completion of well digging, debug the filter layer, test parameters such as water yield and water quality, and select the filter layer to ensure the well water is clean.
