However, with the rapid development of social economy and the rapid advancement of urbanization in various places, the construction and renovation of municipal engineering projects are also accelerating. Traditional cast-in-place concrete retaining walls have gradually shown their disadvantages in actual construction: cast-in-place concrete structures have high requirements for construction sites, the concrete pouring period is too long, and the project cost is high.

[0003] Prefabricated retaining wall panels, prefabricated in factories and installed on-site, offer unique advantages. Furthermore, for areas with poor foundation conditions and a lack of stone, where lightweight walls, minimal floor space, and low foundation bearing capacity are required, prefabricated retaining walls are the optimal choice. However, existing buttress-based prefabricated retaining walls suffer from numerous assembly steps, unstable foundations, and poor integrity. Utility Model Content

[0006] Compared with the existing technology, the advantage of the present invention is that a prefabricated toe plate is used to cooperate with the front toe of the bottom of the prefabricated vertical plate to initially fix the prefabricated vertical plate, and then the prefabricated vertical plate is integrated with the cast-in-place pad and the post-cast heel plate through the casting of the post-cast heel plate, which has strong integrity and stable structure.

[0007] As an improvement, the post-cast heel plate is a reinforced concrete post-cast heel plate; a plurality of steel bar holes are provided at the bottom of the precast vertical plate and are arranged in two rows; a portion of the main load-bearing bars of the reinforced concrete post-cast heel plate passes through the steel bar holes on the same axis of the multiple precast vertical plates, another portion of the main load-bearing bars of the reinforced concrete post-cast heel plate passes through the gap between the front toes and the rear toes below the multiple precast vertical plates, and the stirrups of the reinforced concrete post-cast heel plate are tied between two adjacent precast vertical plates. A portion of the main load-bearing bars of the reinforced concrete post-cast heel plate passes through the steel bar holes of the precast vertical plates, while another portion of the main load-bearing bars passes through the gap between the front toes and the rear toes below the precast vertical plates, and the stirrups of the reinforced concrete post-cast heel plate are tied between two adjacent precast vertical plates, so that the louver-style precast vertical plates, the post-cast heel plates and the cast-in-place pads form a more stable integrated structure with stronger integrity.

[0009] As an improvement, the prefabricated vertical panels are attached to the inclined surface of the prefabricated back panel with plastic steel plates anchored by screws, which are used to position the prefabricated vertical panels before pouring the heel plate after pouring the reinforced concrete, so that the relative positions do not move.

[0010] Preferably, the prefabricated backboard is placed on the rear toe of the prefabricated vertical panel, and the gap between the prefabricated backboard and the rear toe of the prefabricated vertical panel is filled with dry hard concrete and bonded to fix the prefabricated backboard.
