发明名称 Hollow concrete block, e.g. for retaining walls, has curved ends, sides and transverse partitions
摘要 The block (1) consists of a middle section (2) and two ends (3, 4), all with matching convex or concave surfaces. It has three transverse inner partitions, two of which are curved in the same shape as the sides and ends, and the ends can be removed to give a shorter block.
