Drainageschächte

Drainageschächte, also known as drainage shafts or inspection chambers, are essential components of underground drainage systems. Their primary purpose is to provide access for inspection, cleaning, and maintenance of sewers and stormwater pipes. These structures are typically constructed from durable materials such as concrete, brick, or plastic, and are buried below ground level.

The design of a drainageschacht varies depending on its function and location within the drainage network. They are generally cylindrical or rectangular in shape, with a manhole cover at the surface for pedestrian and vehicular access. Inside, the shaft typically features a benching or invert at the bottom where incoming pipes meet and discharge into the outgoing pipe. This invert helps to guide the flow of water and prevent blockages.

Drainageschächte are strategically placed at junctions where multiple pipes converge, at changes in pipe gradient or direction, and at regular intervals along long stretches of pipe. This allows maintenance crews to easily reach different parts of the drainage system. Regular inspection and cleaning through these shafts are crucial for ensuring the efficient operation of the drainage system, preventing overflows, and mitigating potential environmental pollution. They play a vital role in public health and infrastructure management by facilitating the removal of wastewater and surface runoff.
