Revisionsdeckel

Revisionsdeckel is a lid used to close an access shaft or inspection chamber that provides access to underground utility networks and building services for inspection, cleaning, or maintenance. It is installed in floors, sidewalks, or exterior surfaces and is designed to be opened by authorized personnel.

Construction and materials: Typically made from ductile iron, cast iron, steel, or composite materials; the lid sits in a frame and is sometimes sealed with a gasket to prevent water ingress or sewer gas; many are lockable or have tamper-resistant features; some have non-slip profiles.

Application and standards: Used for sewers, water and gas networks, electrical conduits, telecommunications ducts, and building-plant rooms; sizes and shapes vary, commonly round or square; typical dimensions range from about 400x400 mm to 700x700 mm for service shafts; heavier load classes exist for vehicular traffic. In Germany and EU, compliance with EN 124 and national standards; installation requires proper alignment and securing to prevent movement; safety considerations include adequate clearance for maintenance and warning signage; regular inspection for corrosion and seal integrity.

Maintenance and security: When closed, ensures safety and prevents unauthorized access; replacement if damaged; often require professional replacement to maintain seal.
