Austrittslöcher

Austrittslöcher is a German term that translates roughly as exit holes or vents. In technical and engineering contexts it refers to openings that permit the exit of substances from a system, and the meaning can vary by discipline. The common thread is that the hole or opening provides a discharge path for air, water, gas, or other materials.

In mining and tunnel construction, Austrittslöcher are often ventilation shafts or outlets that allow stale air and hazardous gases to escape, while sometimes serving as access points for inspection, drainage, or equipment. They may be natural-looking or deliberately built as part of the infrastructure, and are typically equipped with protective grilles, covers, or piping to control flow and safety.

In geology and hydrology, the term describes natural or artificial openings through which groundwater, steam, or gases can rise to the surface. Such outlets can influence local hydrogeology, form springs, and indicate subsurface flow paths. They may be pressure-relief points in porous rock or fractures and can appear as caverns, fissures, or borehole-type features.

In construction and civil engineering, Austrittslöcher may refer to drainage outlets or relief openings in structures such as retaining walls, basements, or drainage systems. Proper placement and design are important to prevent backflow, erosion, or structural damage.

Overall, Austrittslöcher denote discharge points that relieve pressure or enable material to exit a confined space or system. The precise interpretation depends on the field and the specific engineering or geological context.
