Manual drilling skills

1, find a suitable geomantic place (there is no garbage nearby-to prevent infiltration of underground polluted water, and grass grows on the ground-indicating that the groundwater level is not deep, and there is always new soil to fill the old foundation, so it is necessary to dig a few meters more, and the terrain should not be too concave-there is more hard water in the low ground);

2. After finding a good place, first dig the residual soil with a diameter of 3m and a depth of 2m, then dig a circle with a diameter of 1.5 to 2m in the center, dig it with a spade, level it along the pit wall, stand on the well with four sticks, and lift and move the soil below with a shelf; Dig to about 3 meters, and reinforce the shaft wall with bamboo or sawdust to prevent collapse;

3. After the water comes out, the water is pumped up by the pressure well (mud can't be pumped out). If you encounter a stone, use a pick and a stone hammer to solve it;

4. The depth of artificial well is generally lower than10m. Dig another 3 to 5 meters from the dug water. If this layer is rough quicksand, stop digging;

5. Fill the bottom with medical stone as big as an egg, quartz sand as big as beans, medical stone dug into the river 1 m deep and tourmaline. If possible, use 304 or 365,438+06 stainless steel mesh for silver plating, then wrap the medical stone and fill it in the upper layer of the well. Medical stone is made of permeable bricks, and four neodymium magnet pieces are placed around the bottom of the well. It is surrounded by blue bricks and can be jointed with cement;

6. A round hole or octagonal hole poured with cement at the top 2 meters, on which a cement cover is formed, and a mouth with a diameter of 60 cm is left from top to bottom as the wellhead;

7. Set wheels on it, and build a pavilion on the well to prevent dirt from entering; In the process of excavation, we should pay attention to the collapse of the shaft wall, because there are a lot of medical stone, tourmaline and quartz sand when filling the well, which leads to excellent taste. Silver can release ions for disinfection, and NdFeB can magnetize water to make it mineralized and magnetized.

8. In fact, this well can be a submersible pump or a pressure well; When drilling a well, pneumatic pick, impact hammer (pay attention to leakage prevention), water cannon (fire pump for water cannon, sewage pump for excess water) and electric pulley can be used to lift mud, which is more efficient;
