Betonschächten

Betonschächten, or concrete manholes, are essential underground structures used for access to and inspection of sewer systems, drainage networks, and other underground utilities. They are typically constructed from precast concrete rings that are assembled on-site. The concrete material provides durability and resistance to corrosive substances often found in wastewater.

The primary function of a Betonschacht is to provide a safe and convenient entry point for maintenance personnel. This allows for inspection, cleaning, and repair of the connected pipelines. The manhole shaft consists of a base section, one or more shaft rings, and a cover slab or frame with a manhole cover. The depth of the manhole is determined by the depth of the surrounding pipe network.

Installation involves excavating a pit, placing the base element, and then stacking the precast concrete rings. Joints between the rings are sealed to prevent infiltration of groundwater and exfiltration of sewage. The open shaft is then fitted with a ladder or climbing rungs for access. The top is completed with a frame and a removable cover, which is typically made of cast iron or ductile iron and is designed to withstand traffic loads.

Betonschächten are a cost-effective and robust solution for accessing underground infrastructure. Their modular design allows for flexibility in installation depth and diameter. Regular inspection and maintenance of these structures are crucial for the proper functioning and longevity of the entire underground utility system.
