Patent

CA 2200262

A flexible tubular manhole liner soaked with a curable liquid resin is inserted into a manhole; this liner is already equipped with a number of bolts or sleeve nuts protruding or exposed from the liner surface, by means of which it is possible later to attach to the inner wall of the tubular liner a number of ladder steps and a hose for injecting liquid filler to the gap created between the manhole wall and the liner; there is provided a method to line the manhole with such an inventive liner.

Cette invention concerne un revêtement intérieur tubulaire flexible de regard de visite qui est imbibé d'une résine liquide réticulable. Ce revêtement comporte déjà un certain nombre de boulons ou de manchon filetés faisant saillie ou exposés au moyen desquels on peut plus tard fixer une échelle, ainsi qu'un raccord pour l'injection d'un matériau de remplissage liquide pour combler le vide entre la garniture et la paroi du regard de visite. La méthode de garnissage intérieur au moyen de ce produit novateur est également un objet de l'invention.
