Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic supports, in particular to a shallow-buried pile foundation structure applied to photovoltaic systems. Background Art

[0002] In photovoltaic systems, traditional photovoltaic support foundations mostly adopt deep pile foundation structures, which have the following technical problems: High construction cost: Deep pile foundations require excavation of deep foundation pits, have high requirements for equipment, and result in long construction periods. Especially in complex geological conditions such as ore backfill areas, the construction difficulty increases significantly. Poor geological adaptability: The soil in backfill areas is loose and has low bearing capacity, so deep pile foundations are prone to settlement or inclination, which affects the stability of photovoltaic supports. Large material consumption: Traditional deep pile foundations require a large amount of steel, and fail to make full use of local materials in backfill areas (such as stones), resulting in insufficient economy. Structural redundancy: When single-pile support is adopted in some scenarios, the ability to resist lateral forces is weak, and additional reinforcement measures are required, which leads to a further increase in steel consumption.

[0003] Therefore, in view of the shortcomings existing in the prior art, it is necessary to design a shallow-buried pile foundation structure applied to photovoltaic systems to solve the above problems. Summary of Utility Model

[0004] To overcome the above deficiencies in the prior art, the purpose of the utility model is to provide a shallow-buried pile foundation structure applied to photovoltaic systems.

[0006] In a preferred technical solution: the base is composed of a丰-shaped bottom beam and a steel mesh, the steel mesh is fixedly arranged on the bottom side of the丰-shaped bottom beam, and the pile foundation is fixedly arranged on the top side of the丰-shaped bottom beam.

[0007] In a preferred technical solution: when the pile foundation adopts one first pile body, two opposite sides of the first pile body are both fixedly connected with the base through steel cables, and the other two opposite sides of the first pile body are fixedly connected with the base through diagonal reinforcing bars.

[0008] In a preferred technical solution: when the pile foundation adopts two second pile bodies, the two second pile bodies are fixedly connected with each other through a cross beam and / or a diagonal tension beam.

[0009] Due to the application of the above technical solution, the utility model has the following beneficial effects: The shallow-buried pile foundation structure proposed in this utility model for photovoltaic systems adopts a shaped bottom beam, steel mesh and stone filling to synergistically improve bearing capacity and economy; it uses steel cables or inclined beams to optimize stress distribution and reduce structural redundancy; it specifically solves the support problem of soft foundation in the backfill area and optimizes geological adaptability.

[0014] Example: like Figure 1 As shown, according to a general technical concept of this utility model, a shallow-buried pile foundation structure for use in photovoltaic systems is provided, comprising: Base 1, which is a plate-shaped structure, is used to be embedded in the foundation; The pile foundation 2 is fixedly arranged on the base 1 and used for supporting a photovoltaic support.

[0015] As Figure 1 shown, in an exemplary embodiment of the present utility model, the base 1 consists of a丰-shaped bottom beam 11 and a steel mesh 12, wherein the steel mesh 12 is fixedly arranged on the bottom side of the 丰-shaped bottom beam 11, and the pile foundation 2 is fixedly arranged on the top side of the 丰-shaped bottom beam 11.

[0016] As Figure 1 shown, in an exemplary embodiment of the present utility model, when the pile foundation 2 adopts a first pile body 21, two opposite sides of the first pile body 21 are fixedly connected to the base 1 through steel cables 3, and the other two opposite sides of the first pile body 21 are fixedly connected to the base 1 through diagonal tension bars 4.

[0017] As Figure 1 shown, in an exemplary embodiment of the present utility model, when the pile foundation 2 adopts two second pile bodies (not shown), the two second pile bodies are fixedly connected to each other through a cross beam and / or a diagonal tension beam.

[0018] During on-site construction, a pre-buried pit with a proper size is firstly dug on the ground, then the base 1 is laid in the pre-buried pit, then the pile foundation 2 is fixed on the base 1, and then earth and stone are backfilled into the pre-buried pit, thus completing the installation of the shallow-buried pile foundation structure.

[0019] Summary of advantages of the present application: 1. The shallow-buried structure reduces construction difficulty; the shallow-buried design with a plate-shaped base (丰-shaped bottom beam + steel mesh) eliminates the need for deep foundation pit excavation, and improves construction efficiency by more than 50%, which is particularly suitable for soft geology such as ore backfill areas.

[0020] 2. Structural stability is optimized; the combination of the 丰-shaped bottom beam and the steel mesh increases the contact area between the foundation and the ground, and improves the pull-out resistance and anti-settlement capacity. The single-pile structure is connected with the base through steel cables, and the double-pile structure is connected through the cross beam / diagonal tension beam, forming a stable mechanical system and enhancing wind resistance and seismic performance.

[0021] 3. Material cost is significantly reduced; stones in the backfill area are used to fill the foundation pit, which reduces the consumption of concrete; the diagonal tension bar design reduces the steel consumption for stand columns and pipe piles (an estimated saving of 7.2 tons per MW), which offsets the increase of basic materials, and the overall cost is reduced by 15%-20%.

[0022] 4. Modular construction has high flexibility; standardized prefabricated components (丰-shaped beams, steel meshes) are assembled on site, which can meet the requirements of different terrains and shorten the installation period.

[0023] 5. Environment-friendly; the shallow-buried structure reduces surface disturbance and avoids damage to the ecological environment caused by deep foundation pits; the reuse of local materials conforms to the concept of green construction.

[0024] Therefore, this utility model has the following advantages: The shallow-buried pile foundation structure proposed in this utility model for photovoltaic systems adopts a shaped bottom beam, steel mesh and stone filling to synergistically improve bearing capacity and economy; it uses steel cables or inclined beams to optimize stress distribution and reduce structural redundancy; it specifically solves the support problem of soft foundation in the backfill area and optimizes geological adaptability.
