Abstract
An arrangement in vertical tubular structures, such as rain-water drains and manholes, comprising a plurality of pipe sections placed one upon the other, for preventing the surrounding filling mass from penetrating the joints if the pipe sections move relative to one another. The arrangement comprises a sealing cuff arranged to be placed around the tubular structure in a manner such as to cover the joint between two mutually adjacent pipe sections, and to be pressed sealingly against the outer cylindrical surface of the two pipe sections. The sealing cuff is such as to permit a limited relative movement axially between the pipe sections. Suitably, a protective sleeve made of a rigid material is arranged around the pipe sections beneath the sealing cuff.
