[0025] Further, the lower end of the fixing plate 3 is connected with the base plate 1 through a bolt, after the fixing plate 3 is installed, the clamping block 31 is clamped at the bottom end in the clamping groove 21, so that after the fixing plate 3 is fixed, the stand plate 2 can be prevented from falling off.

[0026] Further, in order to enhance the strength of the fixing plate 3, a protruding plate extending downward is provided at the lower end of the fixing plate 3, and an embedded groove 12 for embedding the protruding plate is provided in the base plate 1, as shown in the accompanying Figure 2 , the size and shape of the embedded groove 12 are matched with the protruding plate, so as to ensure that the fixing plate 3 can remain stable when subjected to external force, and at the same time, the accurate positioning of the fixing plate is facilitated during installation.

[0027] In addition, an auxiliary plate 4 is arranged on the rear side of the fixing plate 3, the auxiliary plate 4 is triangular in structure, cooperates with the fixing plate 3, and can support the vertical plate 2 to avoid the vertical plate 2 from tilting backward under force.

[0028] As shown in the accompanying drawings, adjacent retaining walls are connected by connecting mechanisms 6, the connecting mechanisms 6 include curved rods and straight rods, a square connecting head 61 is arranged at the upper end of the straight rod, one end of the curved rod passes through the connecting head 61, and the end surface is provided with external threads; a nut is connected to each of the two sides of the connecting head 61 and located in the curved rod, and the distance between the vertical part of the curved rod and the straight rod can be adjusted by adjusting the nuts.

In this way, not only can the stable connection between the retaining walls be achieved, but also the deformation requirement of the retaining walls under different soil conditions can be met, whether the two retaining walls are spaced apart or placed at an angle, the connecting mechanism 6 can maintain good connection stability.

[0030] The working principle of the device is as follows: during installation, first, the bottom plate 1 is placed at a predetermined position, the anchor rod passes through the opening on the bottom plate 1 and is tightly fixed with the foundation to lay a stable foundation for the retaining wall. Then, the lower end of the screw rod 5 is screwed into the embedded nut 11 in the bottom plate 1, and the lower end of the vertical plate 2 is placed down with the slot aligned with the screw rod 5 to preliminarily complete the connection between the vertical plate 2 and the bottom plate 1.
