実に防止し得て、実用上有利である。As described in detail above, according to the present invention, vertical holes are formed in the joint arms of the block formed in the Z-shape by the flat plate portion and the joint arms at the both ends, and the block is formed. The entire contact end surface of the joint arm portion contacting the joint arm portion of the other block on the joint surface of the outer periphery is formed into a plane shape substantially at right angles to the stacking direction, and the joint surface excluding the contact end surface is formed of the flat plate portion. A front and back direction of the block, which has an inclined portion which is formed by planarly moving both front and back surfaces in one diagonal direction of one of the four sides, and a first flat portion and a second flat portion which are located at both ends of the inclined portion and have substantially the same width. Since the joint step portion is formed to prevent the displacement in any one direction, the block joint surface can be simplified in shape as compared with the block having the conventional joint step portion, and the block can be easily manufactured. Possible and production It is obtained as a low cost of the strike, which is economically advantageous. Further, when the vertical retaining wall is constructed by forming the entire contact end face of the joint arm part in a plane shape substantially at right angles to the stacking direction and forming the joint step part on the joint face of the block excluding this contact end face. In the lamination of the joining step portion on the lower surface of the upper layer block to the joining step portion on the upper surface of the lower layer block, it is possible to prevent the misalignment caused by a slight deviation in the front and back directions of the block by the contact end surface only by the thickness of the block,
It is possible to improve the workability of constructing the vertical retaining wall as in the case of the conventional block having no joint step. Further, on the joint surface excluding the contact end surface, an inclined portion which is formed by planarly moving both front and back surfaces in one diagonal direction of the four sides, and a first flat portion and a second flat portion located at both ends of the inclined portion are provided. By forming the joint stepped portion, the laminated form of the block can be made constant, and the deviation of the front and back of the block in one predetermined direction can be reliably prevented, which is practically advantageous.
