Manhole and a method for providing a manhole

Abstract

A manhole (40) for desert environments where temperatures can be very high and environmental conditions such as erosion exert different challenges on sewage infrastructure, the manhole including a steel pipe telescope (450) matched to two circular heat resistant sealing rings (460, 461) in a concrete cone (400). The concrete cone is attached to a concrete manhole (410) with a heat resistant seal (462). The position of the concrete cone is stabilised by a large concrete slab (470) at the bottom of the manhole. The cover (430) of the manhole rests on the steel pipe telescope (450), and when the ground level changes, the steel pipe telescope can simply be repositioned within the concrete cone to match the changed ground level. All concrete parts (400, 410, 470) can be casted on-site, which means that preferably both the construction and the maintenance of the manhole happen at the installation site.
