Abstract
A method of soil compaction consists in, during compaction of the soil, applying a smaller auxiliary force around the area of the soil to which a larger compacting force is applied. In soil compacting apparatus a pneumatic tire is used for applying the auxiliary force and the compacting force is applied by a cylindrical or non-cylindrical compacting member located within the tire, the compacting member being adapted to contact the inner surface of the tire for applying the compacting force to the soil. In another embodiment, the compacting member is mounted adjacent the pneumatic tire on a common axle therewith.
Claims4
Soil compacting apparatus comprising means for applying a compacting force to an area of the soil to be compacted and means for applying an auxiliary force to an area of the soil enclosing the area to which the compacting force is applied, in which the auxiliary force applying means comprises a pneumatic tire and the compacting force applying means comprises a cylindrical compacting member within the tire, the cylindrical member being concentric with the tire and having a width which is smaller than the width of the track of the tire when in contact with the ground and the compacting member being arranged to contact the inner surface of the tire and thereby to impart a compacting force to the ground as the tire is moved across the ground.
Soil compacting apparatus comprising means for applying a compacting force to an area of the soil to be compacted and means for applying an auxiliary force to an area of the soil enclosing the area to which the compacting force is applied, wherein the auxiliary force applying means comprises a pneumatic tire and the compacting force applying means comprises a rigid non-cylindrical compacting member within the tire, the compacting member and the tire being mounted for rotation about a common axle and wherein the non-cylindrical member is adapted to impart a series of successive blows against the inner surface of the tire as the tire is rolled across the soil to be compacted.
