Molded elastomeric circular gasket |
摘要 |
A manhole construction for assuring tightly sealing a manhole/sewer pipe connection. The heart of the invention resides in a molded elastomeric circular gasket for resiliently supporting a sewer pipe in a manhole opening and sealing the space between the wall of the opening and the surface of the pipe. The transverse cross-section of the gasket has a generally triangular head, with a forward face provided with an arcuate depressing therein, and a sloping rear face; a generally rectangular body, integral with the generally triangular head and generally "L" shaped leg depending from the body and coextensive with the rear face of the body, the leg of the "L" being directed towards the forward face.
