people who dig wells are not forgotten when they draw water. In the past, every family had a well. The well water is warm in winter and cool in summer. This is because the well water is groundwater. Groundwater is water from rain and snow. It is stored in a small opening through soil filtration. What well can a well drill drill drill?
The five main types of wells are digging, driving, drilling, drilling and jetting (Flushing).
Most digging and drilling equipment is available, or because drilling is considered too expensive, the front hole is built-in. Modern wells are usually lined with concrete tiles and have a large diameter, providing a large opening for the aquifer. This allows them to get water from very fine materials such as sand, silt or clay. The wells are shallow and there is no continuous casing, which makes them polluted by nearby pollution sources.
Drive wells are made by driving small diameter pipes into shallow water, sand or gravel containing sand. The construction of these wells is relatively simple and economical, but they can only dig shallow water and are as easy to be polluted as digging wells.
The drilled well consists of a large auger. The depth of boreholes is usually about 50 to 70 feet. They are usually made of soft materials, such as sand, silt, clay and soft rock.
Use percussive or rotary drilling machines to construct drilling. These wells can be more than 1000 feet deep. Wells that penetrate less hard and firm land require casing and screens to prevent the inflow of sediment, which can lead to well collapse.
Force high-pressure water into underground drilling jet or flushing wells. This construction method can only be used for soft soil foundation.
