Publication number: 20080244988Abstract: Several improved manhole grade rings and methods for providing improved manhole grade rings. In one embodiment, a plurality of concentric annular rings are connected by radial ribs. Certain radial ribs can be broken to provide a manhole grade ring of the desired diameter. In several other embodiments, concentric annular ribs and interconnecting radial ribs provide lightweight stackable manhole grade rings. In another embodiment, a manhole grade ring defines an annular cavity that can be filled to reinforce the manhole grade ring. Two embodiments provide improved forms for pouring manhole grade rings in place. One form provides a plurality of forms of different diameters that can be filled to any height, while another form provides adjustable height of the manhole grade ring.Type: ApplicationFiled: April 3, 2008Publication date: October 9, 2008Inventors: Cynthia R. Meissen, Kyle L. Baltz
