  • the invention relates to a method of fastening including hinging, opening and closing of manhole covers, such as manhole covers in relation to cover bases such as entrance openings for sewer- or waste water line inspection wells.
  • the invention furthermore relates to a mechanism for opening and closing covers such as manhole covers placed on cover bases such as openings for sewer- or waste water line inspection wells.
  • Covers such as so-called manhole covers are typically used at entrance openings of inspection wells by waste water mains, which are often placed in roads.
  • the techniques typically includes opening and closing of lids, where the whole edge of the cover periphery is in contact with the cover base, when the cover is closed.
  • the covers are furthermore typically hinged in relation to the cover base with relatively large and voluminous hinges, which carry the weight of the cover, when the covers are opened.
  • the covers can tilt, when they are subjected to load of e.g. trucks or other heavy vehicles, which drive on the covers.
  • the covers tilt When the covers tilt, they will typically emit noise, which can be a nuisance for nearby residents, and the covers and the hinges can be damaged, resulting in expensive costs.
  • the object of the invention is achieved by a method of the type stated in the introductory portion of claim 1 , which is characterized in that the fastening is established through one or several, preferably four connecting devices and through one or more, preferably two hinges.
  • the hinge consists of one or several, preferably two lower parts, which is integrated in the cover base, and one or more, preferably one top device, which is integrated in the cover, where lower part and upper part is connected through a transverse shaft manufactured of an aluminium bronze alloy, and where the material thickness of the hinge parts between the shaft and the cover in the direction of the cover is smaller than the shaft's cross-sectional diameter, preferably smaller than 0.3 times the cross-sectional diameter of the shaft.
  • the invention also relates to a mechanism.
  • This mechanism is characterized in that the mechanism consists of one or more, preferably four connection devices placed in the periphery, such as in the comers of the cover and cover base with top parts in the cover and lower parts in the cover base, where closing is done by screwing together the top- and lower part by activating a bolt integrated in the top part.

Abstract

L’invention concerne un procédé et un mécanisme d’ouverture et de fermeture de tampons, notamment de tampons de regards d’égout typiquement associés aux ouvertures d’entrée de trous de visite de canalisations d’eaux usées. Le procédé fait appel à des mécanismes de fermeture dotés de petites zones de raccord très faciles à nettoyer relativement à l’ouverture et à la fermeture des tampons. Les mécanismes de fermeture présentent le grand avantage d’assurer la bonne fermeture systématique des tampons suite à un processus de nettoyage simple, en évitant ainsi que ceux-ci ne s’inclinent lors du passage de véhicules lourds, un problème qui affecte la fermeture des types connus de tampons. Les mécanismes de fermeture sont dotés de boulons intégrés permettant d’ouvrir et de fermer facilement et correctement les tampons. L’invention concerne également un nouveau type de charnière, caractérisé en ce qu’il minimise les jours formés entre les tampons et leurs cadres une fois les tampons fermés, en offrant ainsi un excellent confort de conduite aux usagers des routes roulant sur les tampons et en minimisant les problèmes associés à l’encrassement des jours.
