Abstract

La présente invention concerne une unité formant perré en une seule pièce de poids léger. L'unité formant perré 10 comporte un rebord il entourant la gueule d'une partie évidée centrale R La partie évidée est définie par une paroi arrière inclinée ou incurvée 12, des parois latérales opposées 14 et une paroi de fond de préférence plane 13. Une poignée 15 se prolongeant vers l'arrière à partir de la face arrière facilite la manipulation de l'unité et sert comme attache convenable pour le dispositif de fixation 16. Lorsque l'unité est installée dans la paroi d'un fossé, la paroi de fond est sensiblement horizontale et le rebord se confond avec la paroi du fosséThe present invention relates to a lightweight one-piece rip-rap unit. The rip-rap unit 10 has a flange 11 surrounding the mouth of a central recessed portion R The recessed portion is defined by an inclined or curved rear wall 12, opposing side walls 14 and a preferably planar bottom wall 13. A handle 15 extending rearward from the rear face facilitates handling of the unit and serves as a suitable fastener for the securing device 16. When the unit is installed in the wall of a ditch, the wall of bottom is substantially horizontal and the edge merges with the wall of the ditch
