[0019] In summary, when constructing a small retaining wall in a municipal engineering project, a trench is first dug to place the foundation blocks 1. Multiple foundation blocks 1 are arranged horizontally in the trench, and two adjacent foundation blocks 1 are connected by a clamping groove 1.1.1 and a clamping block 1.1.2. The depth of the foundation block 1 buried in the trench is based on the bottom surface of the top block 1.2 being flush with the bottom surface.

[0020] Then, proceed with the stacking of blocks 2, layer by layer, from bottom to top. When stacking the lowest layer of blocks 2, insert the two inserts 2.2 at the bottom of each block 2 into the rectangular slots 1.1.3 of the two adjacent foundation blocks 1 below it. This means the insert 2.2 at the bottom left of each block 2 is inserted to the right of the rectangular slot 1.1.3 at the top of the left foundation block 1 below it, while the insert 2.2 at the bottom right of each block 2 is inserted to the left of the rectangular slot 1.1.3 at the top of the right foundation block 1 below it. The front end of each block 2 in the lowest layer is flush with the front end of the top block 1.3 on the front side of the foundation block 1, and the bottom end of the inclined water guide hole 2.1.2 in each block 2 in the lowest layer aligns with the water guide groove 1.3.1.

[0021] When stacking the upper layer of blocks 2, the two inserts 2.2 at the bottom of the upper block 2 are respectively inserted into the rear notches 2.1.5 of the two adjacent blocks 2 below it. That is, the insert 2.2 at the bottom left of the upper block 2 is inserted to the right of the rear notch 2.15 of the left block 2 below it, and the insert 2.2 at the bottom right of the upper block 2 is inserted to the left of the rear notch 2.1.5 of the right block 2 below it. In addition, the bottom end of the water guide hole 2.1.5 of the upper block 2 corresponds to the top end of the water guide hole 2.1.5 of the lower block 2. The blocks 2 are sequentially retreated from bottom to top, so that they can easily fit the slope.

[0022] When planting plants in the vegetation trough 2.1.1, lay geotextile or filter sheet on one side of the seepage hole 2.1.6.

[0023] U-shaped projections 1.3.2 and U-shaped grooves 1.3.3 are respectively provided at the outer edges of the water channel 1.3.1 at the top of the rectangular column 1.1 and the two side walls of the front top block 1.3. The U-shaped projections 1.3.2 and U-shaped grooves 1.3.3 snap into place. The engagement of adjacent U-shaped projections 1.3.2 and U-shaped grooves 1.3.3 on adjacent rectangular columns 1.1 improves the sealing effect at the joint surface of the water channel 1.3.1.

[0024] The bottom surface of the bottom block 1.2 is provided with a plurality of strip-shaped protrusions 1.4 extending in the transverse direction to increase the friction between the base block 1 and the bottom surface of the groove.

[0025] The front wall of the bottom end of the plug block 2.2 is provided with an inclined surface structure with the bottom end tilted backwards, so as to facilitate the plugging of the plug block 2.2 with the rectangular slot 1.1.3 and the rear notch 2.1.5.
