9.2 Installation horizontally within a Rebar Cage contd…
STEP 1 -
mark the steel at the level the Casing needs to be installed. The top of the Casing
height should be used as it will be easier to see when installing.
If the cage is already in place marks should be made on the rebars using levelling
techniques.
STEP 2
- the first length of Casing can be installed from either end or from the open end if a
dead end pulley system is employed. Each Casing length should be held at both ends in
roughly the correct position and then checked with a spirit level from the top of the Casing to
the level marks on the rebar cage.
When this is fixed in approximately the correct position then it should be held in place
loosely by some tape, making sure that the internal grooves are vertical (by eye is ok at this
stage).
The next stage is to fix the Casing securely starting at the outside end of the first Casing.
STEP 3
- place the installation tool horizontally into the Casing and then place the spirit lev-
el on the plate and rotate the Casing until absolutely horizontal.
