Clamp device for portable porous pavement system

Abstract

A clamping device for a portable porous pavement system includes a first bracket and a second bracket. The first bracket includes a U-shaped section extending between first and second wings; a first slot defined by the first wing; and a second slot defined by the second wing. The second bracket includes a C-shaped member having first and second arms with a base member joining the first and second arms; a first twistable section defined by the first arm; and a second twistable section defined by the second arm. The first arm is sized to fit through the first slot of the first wing such that the first twistable section and the base member are on opposite sides of the first wing; and the second arm is sized to fit through the second slot of the second wing such that the second twistable section and the base member being on opposite sides of the second wing.
