A PROPER GUIDE TO INSTALL BHARAT FRP MANHOLE COVERS & FRAMES
Do not over hang the frame:
The frame should be fully supported on
the chamber wall or slab as shown in
the picture below.
Never cast the frame concealed in the slab
While constructing the manhole, most of
the time the frame is cast along with the
slab. This makes the bearing for the frame
very thin. Due to this, the slab on which the
frame rests will fail. The proper way is to cast
the frame on TOP of the slab as shown in
the picture below.
Top of conical brick, Manhole should be
leveled with concrete
The voids created at the top of conical
brick, the manhole is often left empty.
This creates a gap between bottom surface
of the frame and top of brick work.
The gap is never filled properly while
plastering and hence, should be leveled
with concrete to have perfect contact with
the bottom of the frame.
