CA 2512438

A ramp for a temporarily elevated utility access hole on a roadway includes an annular ramp member that has a positioning mode and a locked installation mode. In the locked installation mode, an interior circumference surface adjacent to a bottom surface constricts to tightly engage the manhole cover support. The annular ramp member is moved from the positioning mode to the locked installation mode upon the annular ramp member being forced in a downward direction to bring the bottom surface in contact with the roadway.

Une rampe pour trou d'accès de servitude temporairement élevé aménagé sur route comprend un élément de rampe circulaire pourvu d'un mode de positionnement et d'un mode d'installation verrouillé. Dans le mode d'installation verrouillé, une surface circonférentielle interne adjacente à une surface inférieure se resserre pour étrangler le support du couvercle de trou d'homme. L'élément de rampe circulaire passe du mode de positionnement au mode d'installation verrouillé, ledit élément étant alors forcé vers le bas afin de mettre la surface inférieure en contact avec la route.
