摘要：
Three types of massive blocks can be examined in the technology of vibration compaction of wet concrete by internal vibrators. The first type is blocks which are completely amenable to compaction by machines. The second type is blocks with various elements inside them, limiting the work of machines and forcing the use also of manual compaction. The third type is blocks in which the indicated obstacles make operation of machines completely impossible. Problems of the production and design of heavy manual internal vibrators are examined.
