The heavy-duty metal construction and robust pipe connection makes it possible to assemble our products on the side of the ditch before placing them. Aluminum in-line assemblies are easy to place manually. An excavator can be used to place the larger flashboard products.
Clearly an excavator can easily smash a box or snap the pipe so careful operation is important.
Backfilling with an excavator is acceptable. Go slow and carefully place loose soil to secure the pipe then backfill the box. A mini is recommended because it is easier to control.
Use caution when backfilling single-sided flashboard risers. The boxes can be pushed forward and the support frames can be bent if dirt is applied too quickly.
Nothing is indestructible but our aluminum inline boxes will take a beating with no damage. The flexible coupling and pipe are the most delicate aspects of the system.
Risers can be set on the ends of an existing pipe. In this example, a new pipe and riser was installed to draw water from this distribution ditch. This new riser is being added to an existing pipe so the water flow can be split and/or switched between pipes.
Carefully and Slowly expose the pipe and level the space below the bottom of the pipe to roughly match up with the stub on the box. A good operator can do this with an excavator but it is best finished with a shovel.
Do not dig too deeply because the box needs firm ground under it.
If the pipe end is damaged, it may need to be sawed off to present a clean end. In this example, the pipe was uncovered in good condition.
Lift the box in place manually or with the excavator.
Wrestle the box into place to get the riser stub inside the pipe. Use a shovel and/or the excavator the gently push the box into place.
Use the excavator and some elbow grease to square up the box into a plumb and level condition. The box is sturdy enough to withstand gentle downward pressure from the excavator to tamp it into place.
If desired, drive rebar pins in the box to secure it. These are not needed if the preparation is good and the box is on a secure footing.
Attach a cleat to hold the pipe and box together. This is important.
