Title (EN) ROAD HAVING CURVED GROOVES
(FR) ROUTE POURVUE DE RAINURES INCURVEES
Abstract:
(EN) An apparatus (10) and method for cutting grooves (140) on the edges of an already formed road (60). Each of a plurality of toothed cutting wheels (40) revolves about a substantially vertical driving shaft (32). Simultaneously, each cutting wheel (40) (attached to a respective rotary shaft (44)) revolves about its own longitudinal and substantially horizontal axis. The apparatus (10) is moved along a road (60), near an edge (62) thereof, thus giving rise to one linear motion and two rotary motions. Sequentially, each cutting wheel (40) enters an edge (62) of the road (60) from a region beyond the road edge (62), due to a slight tilt of the plane which contains the cutting wheel rotary shafts (44). The resultant grooves (140) are deepest at the road edges (62) and then gradually diminish to zero depth, the grooves (140) being arcuate and parallel to each other. With the plane containing the cutting wheel shafts (44) completely horizontal, the apparatus (10) can cut rain drainage grooves in a raised marking strip on the road (60) or can remove bumps from the road (60).
(FR) L'appareil (10) et le procédé décrit servent à pratiquer des rainures (140) sur les bords d'une route déjà formée (60). Plusieurs roues de découpage (40) pourvues de dents tournent chacune autour d'un arbre d'entraînement sensiblement vertical (32). Chaque roue de découpage (40), (fixée à un arbre rotatif correspondant (44)) tourne en même temps autour de son propre axe longitudinal et sensiblement horizontal. L'appareil se déplace le long d'une route (60) à proximité de l'un de ses bords (62), produisant ainsi un mouvement linéaire et deux mouvements rotatifs. Chaque roue de découpage (40) pénètre séquentiellement dans un bord (62) de la route (60) à partir d'une région se trouvant au-delà du bord (62) de la route, en raison d'une légère inclinaison du plan qui comporte les arbres rotatifs (44) des roues de découpage. Les rainures (140) qui en résultent sont plus profondes sur les bords (62) de la route et leur profondeur diminue graduellement jusqu'à être nulle, les rainures (140) étant incurvées et parallèles les unes aux autres. Etant donné que le plan qui comporte les arbres des roues de découpage est parfaitement horizontal, l'appareil (10) peut pratiquer des rainures de drainage de l'eau de pluie dans une bande de marquage surélevée de la route (60) ou peut supprimer les inégalités de la route (60).
