1.7 Distributing Along the Trench
In stringing out pipe, keep these points in mind:
1. Line pipe as near to the trench as possible to avoid excessive handling.
(Bell direction doesn’t affect flow or hydraulic coefficients.)
2. If the trench is open, it is advisable to string pipe on the side away
from excavated earth wherever possible, so that the pipe can be
moved easily to the edge of the trench for lowering into position.
3. If the trench is not yet open, find out which side the excavated earth
will be thrown, then string out on the opposite side (leave room for
the excavator).
4. Place the pipe so as to protect it from traffic and heavy equipment.
Also, safeguard it from the effects of any blasting that may be done.
2.0 Trench Construction
2.1 Working Ahead of the Pipe Laying Crew
Where soil and groundwater conditions permit, long stretches of trench can
be opened ahead of pipe laying, so as to take full advantage of the easy
handling and speed of assembly of JM Eagle IPS Pressure and Irrigation
Pipe with elastomeric joints. However, as a general rule for most jobs, do not
open the trench too far ahead of pipe laying. Avoiding these long stretches of
opened trench may help with the economy of the project because:
1. It may reduce or even eliminate pumping or sheeting.
2. It minimizes the possibility of flooding the trench.
3. It reduces caving caused by ground water.
4. It helps avoid frozen trench bottom and backfill.
5. It reduces hazards to traffic and workers.
On most jobs, it will be desirable to keep excavating, pipe laying and backfilling
close together.
