Description

Technical Field

[0002] A plate compactor is a mechanical device used for soil compaction, also known as a vibration compactor or a vibration plate. It is mainly composed of a vibration mechanism, a base plate and an operating handle. During construction, the plate compactor applies vibration force and pressure through the base plate to compact the soil particles tightly, thereby increasing the density and bearing capacity of the soil. Usually, the shape of the base plate of a traditional plate compactor is generally simple, mainly flat, which easily leads to vibration and pressure being concentrated mainly in the center area of ​​the base plate, causing the problem of excessive single-point pressure. This may lead to poor soil compaction in the edge area around the base plate, uneven compaction, low compaction efficiency and other problems, thus proposing a curved base plate for a plate compactor.
