ABSTRACT:
A pipeline 1 crosses a manhole 2 with a degree of clearance and is provided, inside the manhole, with a vertical pipe 19 capped with a removable sealing cover 22. The movement of the pipeline in relation to its surroundings is thus enabled without it being necessary for the manhole to be sealed. The cover is provided with a drainage valve 32 operable from the top of the manhole by a chain 33.
