Which elevated well pipes are best used

The site is located on a hill, presumably on a rock. I wanted to know which tubes are best used for a well. The depth is approximately 45 m. To prevent the well from crushing when shifting the earth’s crust.

Hello!

Andrey, it’s best to equip your well according to the following scheme. Strengthen the upper, soft layers of the soil with a steel casing with a diameter of 133 mm. It is brought into the rock not less than 1 meter, and if it is subject to cracking, more than 5 meters. This will seal the well from the ingress of groundwater and high water.

A polyethylene casing pipe with a diameter of 127 mm is installed inside the metal string so that it enters the rock 2-3 m below the steel. It is sealed by drilling a special pocket in the rock.

In some cases, a plastic pipe is installed over the entire length of the well, for example, with increased fracturing of the rock, which leads to the entry of the overhead column. In any case, it will be possible to draw a conclusion about the need for full casing only by drilling results.
