[0002] As an important structure, the main function of the rear retaining wall masonry structure is to support the roadbed fill or hillside soil and prevent the fill or soil from deforming and becoming unstable. With the acceleration of urbanization and the continuous improvement of infrastructure construction, the requirements for the rear retaining wall masonry structure are also increasing.

[0003] However, the construction of existing rear retaining wall masonry structures usually requires tedious processes such as on-site formwork installation, steel bar binding, and concrete pouring. These processes not only consume a lot of time, but also fail to meet the needs of modern fast-paced construction. Secondly, when the existing rear retaining wall masonry structures are under pressure, due to their single structural form, they are often difficult to effectively disperse and resist pressure, and are prone to collapse and tilting, which not only affects the service life of the rear retaining wall masonry structures, but also poses a potential threat to the surrounding environment and personnel safety. In addition, the existing rear retaining wall masonry structures often fail to take into account possible future expansion needs and lack corresponding expansion connectors, which makes it difficult to expand the use function of the rear retaining wall masonry structures in the future.

[0004] Therefore, it is very necessary to invent a kind of rear retaining wall prefabricated brick and rear retaining wall masonry structure. Utility Model Content
