dränrohre

Dränrohre, also known as drainage pipes, are perforated conduits used to collect and remove excess groundwater from soil. They are typically made of plastic, such as PVC or polyethylene, and are characterized by small holes or slots along their length that allow water to enter. The primary purpose of dränrohre is to prevent waterlogging, which can damage foundations, cause soil erosion, and negatively impact plant life.

These pipes are commonly installed in agricultural fields to improve soil aeration and drainage, leading to better crop yields. In construction, they are used around building foundations to protect against moisture damage and basement flooding. They are also employed in civil engineering projects, such as road construction and retaining walls, to manage subsurface water levels.

The installation process usually involves excavating a trench, laying a layer of gravel, positioning the dränrohre, and then covering it with more gravel and soil. The pipes are typically laid at a slight gradient to ensure gravity facilitates water flow towards an outlet, which can be a drain, a ditch, a soakaway pit, or a pumping station. The effectiveness of a dränrohr system depends on proper design, installation, and maintenance to prevent clogging by sediment or roots. Regular inspection and cleaning are often necessary to ensure continued functionality.
