HOW TO SET SLOPES (FALLS/GRADES)

Working Example 2 (when you do NOT know the grade to set)

Note:

If the laser is switched oﬀ and on again, this value is lost; as the laser reverts back to auto

level.

Keep the detector clamped in place on the measuring staﬀ & by moving between covers

A

&

B

,

keeping a continuous tone on the detector, the ground can be cut away at the base of the staﬀ ,

following the grade set by the laser.

Obviously, allowance must be made for the actual depth of the pipes’ exit & entry positions in

each manhole.

Grade Ratio

As an example, if distance “

D

” is 20m (20,000mm) & fall “

F

” is 250mm, the formula shown below

determines the Grade ratio:

Distance “

D

” in mm / Fall “

F

” in mm = Grade ratio.

i.e. 20,000/250 =

80

A

1:80

Grade (fall) is used typically for a foul drain run.
