Выражение встречается в следующем контексте:

For the present project, the laying technique for the shallow water soft soil of Kairan-Aktote area the ‘Big Wheel Roller’ will be used instead of tugboats.
Trenching Rollers are like Road Rollers, with a profile mounted around their wheels . The weight of the Roller pressed this profile into the soil, using the softness of the soil to its advantage. Such profiled Rollers are used to make small ditches. These ditches are remarkably stable, as their top layer has been compacted by the force of the roller.
