When an excavator digs down, unless it is fitted with lasers the trench floor will be uneven. With trenchers an even floor is formed; if sanding of the ditch is needed less material is needed. Trenching offers not only a smooth floor, but smooth sides.
When an excavator lifts up its bucket to dump, the ditch stops, but with chain trenchers it just keeps cutting.
The soil from excavators is removed in clumps - even more in black soil. The trenchers grind soil into a fine state, which makes good backfill. The soil can be put on each side of the trench, whichever you require.
Trenching, is to all intents and purposes like digging a long thin hole, maybe 10 inches wide, and 2 feet deep, for 100 yards. That would be a large job, to complete with a spade.
A trenching machine, is similar to a large chain saw, a trenching machine digs up the ground to a certain depth, and certain width. Most notable, trenching would be required for creating of footings, irrigation lines, cable lines, pipes, underground utilities, water lines, gas lines, pool lines, and more.
These machines are purpose built in the United States and designed for extraordinary soil and rock conditions. The cutting chain uses tungsten carbide tipped digging teeth to "grind" the ground as it moves along.
The action of cutting excavates the soil, or booty, from the trench at the same time, bringing it up to the pinnacle of the digging face where it is dropped on to a conveyor.
The conveyer can be moved to the left or right and discharges the 'spoils ' into rows at a destined distance from the trench. As the rows are set away from the trench edge, access by machinery and personnel is less constrained and allows for a better; work environment.
On jobsites where you can mechanically backfill with a blade or bucket without damaging turf, sizeable, open-cut ditches are easy to cover quickly. But you still need to dedicate work and machine resources to backfilling.
Are there options that are more labor-efficient and less harmful to landscapes? Fortunately , yes.
Many irrigation contractors have vibratory plows, mini-trenchers and mini-loaders in their equipment armoury. These machines can be less damaging, more lightweight or, with the utilising of different attachments, more flexible than conventional trenchers.
They also minimise taxing labor which, potentially, might be one of the most important advantages in the current day's labor-shy working environment.
