Kaevutorud

Kaevutorud are pipes used in the construction of water wells. Their primary function is to line the excavated borehole, preventing collapse of the surrounding soil or rock and ensuring a stable pathway for water to enter the well. These pipes are typically made from durable materials such as PVC, HDPE, or metal, chosen for their resistance to corrosion, pressure, and the specific geological conditions of the site. The diameter of the kaevutoru is determined by the intended use of the well and the type of pumping equipment that will be installed.

Installation involves lowering the kaevutoru into the drilled well and securing it in place, often with gravel pack or grout. The lower section of the kaevutoru may be perforated or screened to allow water to flow into the well while preventing the entry of sediment. The integrity of the kaevutorud is crucial for the long-term functionality and water quality of a well. They protect the aquifer from surface contaminants and maintain the structural stability of the well over time. Various regulations and standards often govern the materials and installation methods for kaevutorud to ensure public health and environmental safety.
