A DUCT ELEMENT, A DRAIN PIPE EMPTYING SYSTEM AND METHOD FOR TEMPORARILY DISCONNECTING AN OUTLET PIPE OF A BUILDING FROM A SEWER MAIN.

摘要

The application describes a duct element (2) for use in a sewage system. The element comprises an inlet structure (4) configured to couple the duct element with a first drainpipe of the sewage system, an outlet structure (6) configured to couple the duct element with a second drainpipe of a sewage system; and, an intermediate structure (8) forming a duct between the inlet structure (4) and the outlet structure (6). The intermediate structure (8) comprises an opening (8A) to provide access to the inlet structure and outlet structure. The intermediate structure comprises a space (8B) which enables the duct element to collect a minimum amount of sewage before sewage is collected in the inlet structure (4) and enables a pumping device (42) to drain sewage from the space (8B) allowing sewage present in the inlet structure (4) to flow in the space (8B).
