How to select the drilling section.
Drilling machine
When selecting the place for drilling wells, try to avoid selecting suburban or smaller towns or rural areas, because the sewage or drainage facilities in these places are not sound enough, so it is easy to pollute the water quality of the wells. In addition, some suburban or village areas have some farmland or vegetable fields, and the current crops are all applied with chemical fertilizers and pesticides. Therefore, if these pesticides and fertilizers are not easy to decompose in the land, they will seep into the underground water with the water source. Therefore, we should keep away from the polluted areas as far as possible when drilling wells. If there are farmland or vegetable fields around, it is suggested to drill the well deeper and make anti-seepage treatment around the well if the well drilling machine cannot be avoided. Hollow cement columns can be used to form isolation.
In addition, it is necessary to avoid rocks when selecting the section where the drilling machine is drilling, because the underground conditions are complex and changeable. The shallow layer of the underground stratum (within several kilometers) is layered, and there may be special geological phenomena such as fold fracture, basement uplift and depression. Therefore, if it is not a fixed location, it is difficult to describe the underground geological conditions of a specific location with the underground conditions of a certain region.
