The transverse prestressed steel bars 32 extend into the vertical prestressed steel bars 12 and are fixed to the vertical prestressed steel bars 12 at intersection.

[0037] The working principle and beneficial effects of the above embodiments are as follows:

[0038] The crown column 1 of this utility model is inserted into the foundation to provide vertical support. The crown plate 2 is inserted between the two crown columns 1. The crown beam 3 is fastened to the upper end of the crown plate 2. The crown beam 3 is connected to the crown column 1 through the transverse prestressed steel bar 32 to form a stable frame structure, which can effectively resist lateral pressure and enhance the overall stability of the structure.

[0039] This utility model retaining wall structure adopts a modular design. Each support unit consists of a crown column 1, a crown plate 2, and a crown beam 3, which facilitates factory prefabrication and on-site assembly, improving construction efficiency and quality control.

[0040] like Figure 4 As shown, local signs are engraved on the crown plate 2. Because the retaining wall structure adopts a modular design, it has uniformity and a cleaner and more beautiful appearance, which helps to improve the overall image of the project.

[0041] In one embodiment,

[0042] It also includes an anchor plate 4, which is arranged on the column 11 and at the same height as the beam 31.

[0043] In one embodiment, such as Figure 5 As shown,

[0044] Grooves 13 extend longitudinally on opposite sides of the column body 11, and tenons 21 extend longitudinally on the surface of the crown plate 2 that abuts it. The grooves 13 and tenons 21 are properly engaged.

[0045] The meshing design of the groove 13 and the tenon 21 can improve the connection strength and tightness between the crown column 1 and the crown plate 2, and enhance the stability and seismic performance of the entire retaining wall structure.

[0053] In one embodiment,

[0054] The transverse prestressed steel bar 32 is arranged in an L-shape, and its length is set to 1 / 2 of the length of the column body 11.
