Description

Technical Field

[0001] This utility model relates to the field of building facilities technology, and in particular to a precast pile-supported cantilever retaining wall. Background Technology

[0002] In the field of civil engineering, retaining walls are a common structural form used to prevent soil sliding and maintain slope stability. They are widely used in road construction, building foundation pits, and mountain construction. Their importance is becoming increasingly prominent, especially in urban construction and construction in complex terrain.

[0003] Traditional retaining wall structures come in various forms, such as gravity retaining walls and cantilever retaining walls. Gravity retaining walls rely on their own weight for stability, but they suffer from problems such as large material consumption and significant soil pressure behind the wall. Cantilever retaining walls consist of a vertical wall, a toe slab, and a heel slab, reinforced with reinforced concrete to enhance their load-bearing capacity. However, in existing technologies, whether gravity or cantilever retaining walls, when a single wall is impacted, it is prone to triggering a chain reaction, affecting the stability of nearby retaining walls and causing a row of retaining walls to collapse. This is because existing retaining walls lack effective independent support structures and buffer designs. When one wall is impacted, it cannot effectively disperse and absorb the impact force, causing the impact force to be transmitted to adjacent walls, ultimately leading to the instability of the entire structure. Utility Model Content

[0004] The purpose of this utility model is to provide a precast pile-supported cantilever retaining wall that can overcome the shortcomings of existing retaining walls that are prone to chain reactions after being impacted.

[0005] To achieve the above objectives, a precast pile-supported cantilever retaining wall is provided, comprising a precast pile body, a retaining plate fixedly connected to the upper side wall of the precast pile body, a supporting base plate fixedly connected to the upper side wall of the retaining plate, a rib plate fixedly connected between the supporting base plate and the retaining plate, and a plurality of anti-detachment base plates provided inside the supporting base plate, with a connecting sleeve fixedly connected to the upper side wall of each anti-detachment base plate.

[0006] The front and rear side walls of the supporting base plate are each provided with a connecting plate. A steel plate is fixedly connected to the side wall of each connecting plate away from the center of the supporting base plate, and an anti-detachment side plate is fixedly connected to the side wall of each connecting plate close to the center of the supporting base plate.

[0007] According to the aforementioned precast pile-supported cantilever retaining wall, the precast pile body, retaining plate, supporting base plate, and rib plate are integrally cast with concrete, which improves the overall structural strength of the retaining wall and greatly simplifies the installation process of the retaining wall.

[0008] According to the aforementioned precast pile-supported cantilever retaining wall, the connecting sleeve has a threaded inner groove inside. The connecting sleeve can be fitted with lifting rings when the retaining wall is hoisted, and decorative accessories such as street light components and protective spikes can be installed after the retaining wall is installed.

[0009] According to the aforementioned precast pile-supported cantilever retaining wall, at least four steel plates are provided, which are evenly distributed on the front and rear side walls of the supporting base plate. The steel plates are attached to the front or rear side walls of the supporting base plate, and adjacent retaining walls are fixed by welding between the steel plates.

[0010] According to the aforementioned precast pile-supported cantilever retaining wall, at least three connecting plates are fixedly connected to each of the steel plates. The connecting plates are perpendicular to the steel plates and perpendicular to the anti-detachment side plates, which can effectively prevent the connecting plates from loosening from the retaining wall.

[0011] According to the aforementioned precast pile-supported cantilever retaining wall, each connecting plate is provided with a shrinkage hole inside, and the left and rear side walls of the connecting plate are provided with shrinkage grooves. The shrinkage holes and grooves allow the connecting plate to separate from the anti-detachment side plate after the retaining wall is impacted, reducing the impact transmitted from the retaining wall to nearby retaining walls.

[0012] According to the aforementioned precast pile-supported cantilever retaining wall, longitudinal steel bars are provided inside the front and rear side walls of the supporting base plate, and horizontal steel bars are provided inside the lower side wall of the supporting base plate, which can effectively improve the overall structural strength of the supporting base plate.

[0013] According to the aforementioned precast pile-supported cantilever retaining wall, a ring of transverse steel bars is provided inside the retaining plate to improve the overall structural strength of the retaining plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. Compared with existing technologies, this utility model effectively transfers the force of a single retaining wall to the deep foundation by using precast piles. The precast piles, deeply embedded in the foundation, evenly distribute the loads of the superstructure and soil into a deeper, stable stratum, preventing the entire retaining wall from collapsing due to impact. This structural form effectively solves the problem in existing technologies where, when a single wall is impacted, the impact force is easily transmitted to adjacent walls, causing a row of retaining walls to collapse. It forms a stable support system, improves the overall structural reliability, and ensures the stability of slopes and foundation pits.

[0016] 2. Compared with existing technologies, the precast pile-supported cantilever structure makes the retaining wall's stress distribution more rational. The cantilever structure, composed of retaining plates, ribs, and a base plate, effectively resists lateral soil pressure under the support of precast piles. The precast piles, retaining plates, ribs, and base plate work together to share the load, enhancing the structure's integrity and stability. Simultaneously, this structure improves the stability of the soil behind the wall, reduces soil deformation, better ensures the safety of slopes and foundation pits, and improves the overall quality of the project.

[0025] Reference Figure 1-4 This utility model provides a precast pile-supported cantilever retaining wall, which includes a precast pile body 1, a retaining plate 2 fixedly connected to the upper side wall of the precast pile body 1, a supporting base plate 3 fixedly connected to the upper side wall of the retaining plate 2, and a rib plate 4 fixedly connected between the supporting base plate 3 and the retaining plate 2. The precast pile body 1, the retaining plate 2, the supporting base plate 3, and the rib plate 4 are integrally cast with concrete, which improves the overall structural strength of the retaining wall and greatly simplifies the installation process of the retaining wall.

The connecting sleeve 6 has a threaded inner groove 601 inside. The connecting sleeve 6 can be used to install lifting rings when hoisting the retaining wall. After the retaining wall is installed, street light components and decorative accessories between the protective spikes can be installed.

[0027] Connecting plates 503 are provided inside the front and rear side walls of the supporting base plate 3. Each connecting plate 503 is fixedly connected to a steel plate 5 on the side wall away from the center of the supporting base plate 3. There are at least four steel plates 5, which are evenly distributed on the front and rear side walls of the supporting base plate 3. The steel plates 5 are in contact with the front or rear side walls of the supporting base plate 3. Adjacent retaining walls are fixed by welding between the steel plates 5. At least three connecting plates 503 are fixedly connected to each steel plate 5. The connecting plates 503 are perpendicular to the steel plates 5 and perpendicular to the anti-detachment side plate 504, which can effectively prevent the connecting plates 503 from loosening with the retaining wall.

[0028] A side plate 504 is fixedly connected to the side wall of the connecting plate 503 near the center of the supporting base plate 3. Each connecting plate 503 has a collapse hole 502 inside, and a collapse groove 501 is provided on the left and rear side walls of the connecting plate 503. The collapse holes 502 and collapse grooves 501 enable the connecting plate 503 to separate from the side plate 504 after the retaining wall is impacted, thereby reducing the impact transmitted from the retaining wall to nearby retaining walls.

[0029] The front and rear side walls of the supporting base plate 3 are provided with longitudinal steel bars 8, and the lower side wall of the supporting base plate 3 is provided with horizontal steel bars 9, which can effectively improve the overall structural strength of the supporting base plate 3. The retaining plate 2 is provided with a ring of transverse steel bars 7, which improves the overall structural strength of the retaining plate 2.

[0030] Working Principle: In operation, the precast pile-supported cantilever retaining wall of this invention first has its main body 1 deeply embedded in the foundation, providing stable foundation support for the entire structure. While bearing vertical loads, the main body 1 also plays a crucial role in resisting lateral soil pressure. When the soil exerts lateral pressure on the retaining plate 2, the retaining plate 2 transfers the force to the rib plate 5 and the supporting base plate 3, forming an integrated cantilever structure to resist this pressure. The precast pile body 1 effectively transfers some of the lateral pressure to the deep foundation, reducing the bending moment and shear force borne by the supporting base plate, thereby improving the stability and bearing capacity of the entire structure. Simultaneously, the interaction between the precast pile bodies 1 enhances the integrity of the retaining wall, allowing the impact force to be dispersed and absorbed by the precast piles when a single wall is impacted, preventing the impact force from being transmitted to adjacent walls. This prevents a row of retaining walls from collapsing due to damage to a single wall. Furthermore, the base plate, working together with the precast piles to bear soil pressure and the weight of the superstructure, further improves the stability of the structure. The reinforcement design of the base slab enables it to effectively resist bending moments and shear forces, ensuring structural safety under complex stress conditions. The entire precast pile-supported cantilever retaining wall, through the coordinated work of its components, effectively resists lateral soil pressure and absorbs impact forces, ensuring the stability of slopes and foundation pits.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
