Abstract
An apparatus for monitoring soil compaction using a compaction machine which applies periodic impact blows to the soil surface. The apparatus comprising a rotatable, multi-sided compactor mass that applies periodic impact blows to the soil surface when rolled over that surface. Data related to the level of compaction of the soil surface is derived, during compaction of the soil surface, from the deceleration of the compactor mass as it impacts the soil surface. This is achieved using one or more accelerometers mounted on the impact compactor.
Claims16
A soil compaction apparatus, comprising:
- a compactor mass;
- a transport device rotatably supporting the compactor mass for the compactor mass to apply a plurality of periodic impact blows to a soil surface by rolling the compactor mass over the soil surface;
- a sensor attached to the compactor mass and transmitting a mass-acceleration-signal representing a varying acceleration of the compactor mass, due to the plurality of periodic impact blows of at least one portion of the compactor mass against the soil surface while the compactor mass is rotated over the soil surface;
- and
- a processor in communication with the sensor and transforming the mass-acceleration-signal into a plurality of data representing a level of compaction of the soil surface.
