The invention discloses a stowage type retaining wall block, comprising a bottom plate, a surface wall and a left and a right sidewall; wherein, the surface and the left and right sidewalls are vertical to the bottom plate of the block; a cavity is formed among the bottom plate, the surface wall and the left and right sidewalls; solid backfill is filled in the cavity while in construction; a plurality of retaining wall blocks are connected with each other by shape matching, so as to form a wall body. The stowage type retaining wall block has the advantages that the product weight is relatively light; the carrying, lifting and long distance transportation in constructing process is convenient; different materials can be backfilled in the surface layer structure of the wall surface; the block weight is increased to meet the requirement for stabilization; the selection of backfill can adopt the solid waste such as building waste and coal ash, which can effectively reduce the effect of waste on environment; the wall body building method is relatively simple.
