In addition, in this embodiment, the large end side wall of the first brick body 11 is integrally translated inward to form the recess 4, and the bottom end of the inner wall surface of the large end side wall of the second brick body 12 is translated to widen inward to form the half bottom 5.

As shown in fig. 20, when two blocking and locking bricks of the upper and lower layers are built, the blocking and locking bricks of the upper and lower layers face the same direction, at this time, the front and rear ends of the blocking and locking bricks of the upper and lower layers have non-overlapping areas 6, and a part of through holes are exposed in the middle of the non-overlapping areas 6, so that the blocks can be used for greening.

Example 12

As shown in fig. 21 and 22, in the application of the greening type blocking and locking bricks, the blocking and locking bricks are built into a vertical retaining wall, and similarly, when the blocking and locking bricks are built, adjacent blocking and locking bricks in the transverse direction are alternately staggered in height, and the blocking and locking bricks are matched with each other through the mutually staggered lugs 2. When two blocks of fender lock bricks of upper and lower floor are built, keep off the rotation of lock brick 180 on upper strata, build again, keep off lock brick front and back head and appear non-overlapping area 6 from top to bottom this moment, expose partial through-hole in the middle of non-overlapping area 6, can be used to planting technique, this is the technical problem that prior art can not solve.
