[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] The utility model is convenient for assembling the existing retaining wall. At the same time, the hollow setting in the block can wrap the geogrid from the middle of the block, and then add gravel to fill it, forming a reinforced earth retaining wall structure with the rear soil. At the same time, the gravel plays a role of water permeability. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example: Figure 1-3As shown, the utility model provides a PC reinforced soil assembled retaining wall, comprising a first building block 1, a second building block 11 and a third building block 12, which are stacked in sequence from bottom to top, and the first building block 1 and the second building block 11 are fixed with two symmetrically arranged positioning blocks 14, a groove 13 is penetrated through the middle end of the upper end of the first building block 1, the second building block 11 and the third building block 12, and a positioning groove 15 corresponding to the positioning block 14 is provided below the second building block 11 and the third building block 12 on the first building block 1, and the overall shape of the first building block 1, the second building block 11 and the third building block 12 is a trapezoidal shape that is wide in the front and narrow in the back, so that they can turn to adapt to different engineering sites.

[0019] Forklift slots 17 are provided on the side walls of the first building block 1, the second building block 11 and the third building block 12. The forklift slots 17 can directly facilitate the staff to transport the produced first building block 1, the second building block 11 and the third building block 12 directly by forklift, thereby improving the convenience of transportation.

[0020] The first building block 1, the second building block 11 and the third building block 12 are all fixedly provided with hooks 16 on their upper surfaces. The hooks 16 provided on the first building block 1 and the second building block 11 are fixedly set in the positioning grooves 15. Such a setting can prevent the surfaces from being completely fitted together during assembly, thereby improving the integrity of the assembly.
