Title: Lined manhole assembly and liner.
Inventor: STRICKLAND JAMES K
IPC: B28B19/00
Filed: 1994-02-10
Abstract: A plastic liner (200) for protecting a concrete manhole interior surface from corrosion wherein the liner includes provisions for creating a strong interlock between the liner and the interior surfaces. A side of the liner which includes the provisions has a plurality of raised hollow projections (206, 208) with spaced sections. The mechanical lock is created when concrete is poured against the side of the liner with the projections.
