Promising Machine for Compacting Road-Building Materials

摘要

The choice of the design type of sealing machines depends on many factors: the type of compacted material (soil, crushed stone, gravel, slag, rock coarse soils, asphalt concrete, concrete); the state of the soil (optimal humidity, waterlogged, watering, bulk, subsidence); the thickness of the compacted layers (layer-by-layer compaction thin layers, compaction immediately to the entire thickness of the filling to the design mark); and the working conditions of the machine (cramped working conditions, a wide range of works). The article presents the design of the aggregate for deep soil compaction, developed by the specialists of the Institute of Hydrodynamics "Siberian branch of the Russian Academy of Sciences" (SB RAS). Based on the assessment of the advantages and disadvantages of this unit, a new technical solution based on a cone-shaped roller is proposed, which provides more favorable conditions for the removal of air from the mass of the compacted material. A mathematical model of a cone rollout using the method of decomposition of the periodic function into a Fourier series is presented. The design of a physical model of a cone-shaped roller in the form of a single roller and a self-centering working body with several rollers is considered.
