"compaction hammer"的定义和意义

What is a "compaction hammer"?

A compaction hammer is a tool used to compact or compress soil, gravel, or other materials to increase their density and stability. It typically features a heavy, flat head that is dropped repeatedly onto the surface to apply force. This action helps to reduce air gaps within the material, making it stronger and less likely to shift or settle over time. Compaction hammers are commonly used in construction, road building, and landscaping to prepare foundations, roads, or pavements. They ensure that the materials are firmly packed, which is crucial for the durability of the finished structure.
