In other embodiments, the large through hole 10a may be divided into several small through holes, or the body 10 may be a solid body.

A groove 14 is formed between the first tooth block 12 and the second tooth block 13 on the same side of the body 10; the recess 14 can receive either the first tooth block 12 or the second tooth block 13 of the other block.

The first tooth blocks 12 are located on two sides of the front wall 11 of the body, and are integrated with the front wall of the body, and the body is provided with a front wall surface 15 and a top surface 16. The second tooth block 13 is offset from the rear wall surface by a distance. During the building, the front wall 15 faces outwards, and the back face opposite to the front wall faces the slope protection foundation and is not visible.

The building block also comprises a shape-modifying block 17 extending from the lower half part of the front wall surface, wherein the shape-modifying block 17 is in a rectangular block shape, has the same width and the same bottom as the body, and has the height which is half of the height of the building block body. The shape-modifying block 17 can fill the gap between the front walls of the left and right adjacent blocks during stacking so that the shape-modifying block is in alignment transition with the front wall surfaces (upper half parts) of the left and right adjacent blocks and the top plane is in alignment transition.

In the building process, the building mode of the building block is as follows: the front wall faces outwards, the blocks are piled up in a way of backing one grid backwards, the upper and lower layers of blocks are staggered in the height direction, and the blocks are aligned and stacked by taking the front wall surface of the shaping block 17 as a reference. Specifically, the lower half of the first tooth block 12 is in plug-in interlocking with the groove of the underlying block, and the upper half of the second tooth block 13 is in plug-in interlocking with the groove of the overlying block.

As shown in fig. 2, in the retaining wall system formed by stacking blocks, the same block can form two continuous extending straight steps (two steps), one straight step is formed by the exposed front wall 11 of the block and the modified blocks 17 of the left and right adjacent blocks, and the other straight step is formed by the modified blocks 17 of the block and the front wall 11 (upper half portion) of the left and right adjacent blocks.

According to the invention, the shape-modifying block is combined with the existing building block structure, so that two straight steps are formed on the basis of keeping the locking function, and the problems that the building blocks are placed in disorder as a whole, adjacent building blocks are not coplanar, and the straight steps cannot be formed are solved.

In this embodiment, receiving refers to a mating interlock between the recess and the tooth block, and in other embodiments, receiving may also refer to a mating abutment relationship, as shown in fig. 24, where one side of the recess abuts the tooth block.

Example two
