Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation, and in particular to a mountain photovoltaic pile foundation structure. Background Technology

[0002] Photovoltaic pile foundations are the basic structures used to support and fix solar photovoltaic panel arrays. During the construction of photovoltaic pile foundations, a rotary drilling rig is usually used to drill holes first, then a pre-made steel cage is placed into the pile hole, then a pre-embedded sleeve is fixed to the steel cage, and finally concrete is poured to fill the pile hole and solidify to form a solid foundation structure.

[0003] Currently, after the concrete is poured for the pile foundation, a circular mold needs to be placed on the pre-embedded sleeve, and concrete is poured to realize the construction of the pile head.

[0004] However, the current pile head and pile body have the same diameter, which makes the effective cross section of the concrete around the embedded sleeve small. In addition, the pile heads are all plain concrete, which needs to withstand a large horizontal force. In extreme windy weather, the pile head is prone to cracking and breaking, which can lead to damage or collapse of the photovoltaic power generation equipment. This needs to be improved. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a mountain photovoltaic pile foundation structure that can prevent cracking and breakage at the pile head.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a mountain photovoltaic pile foundation structure, comprising:

[0007] The pre-embedded sleeve is vertically inserted into the pile hole at its lower end;

[0008] The reinforcing cage is vertically installed inside the pile hole and connected to the lower end of the pre-embedded sleeve;

[0009] The steel cage includes vertical bars and stirrups. The vertical bars are fixed around the pre-embedded sleeve, with the upper end inclined outward and extending to the outside of the pile hole. The stirrups are spirally wrapped around the outer wall of the vertical bars.

[0010] A concrete pile includes a pile body and a pile head, wherein the pile body is cast into a pile hole, and the diameter of the pile head is larger than the diameter of the pile body and is located outside the pile hole.

[0011] In a preferred embodiment, the present invention can be further configured such that the bending position of the vertical reinforcement is located below the opening position of the pile hole.

[0012] In a preferred embodiment, the present invention can be further configured such that the upper end of the vertical rib is bent downward and provided with a hook.

[0013] In a preferred embodiment, the present invention can be further configured such that the outer wall of the pre-embedded sleeve is provided with a clamp for holding the vertical rib.

[0014] In a preferred embodiment, the present invention can be further configured such that the outer wall of the pre-embedded sleeve is provided with an anti-rust coating.

[0015] In summary, this utility model has the following beneficial effects: by setting a reinforcing cage with a trumpet-shaped opening at the top and extending the reinforcing cage to the outside of the pile hole and located inside the pile head, the shear and flexural strength of the concrete pile at the pile head node above the ground is improved, and the concrete inside the pile head node forms a whole with limited lateral deformation, thereby improving the structural strength of the concrete pile and preventing cracking and breakage at the pile head due to strong winds.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] like Figure 1 As shown, a mountain photovoltaic pile foundation structure includes a pre-embedded sleeve 1, a steel cage 2, and a concrete pile 3.

[0020] like Figure 1 As shown, the lower end of the pre-embedded sleeve 1 is vertically inserted into the pile hole, extending 300mm into the pile hole. The reinforcing cage 2 is vertically installed in the pile hole and connected to the lower end of the pre-embedded sleeve 1.

[0021] like Figure 1 As shown, the steel cage 2 includes vertical bars 21 and stirrups 22. The vertical bars 21 are fixed around the pre-embedded sleeve 1, with the upper end inclined outward and extending to the outside of the pile hole. The stirrups 22 are spirally wrapped around the outer wall of the vertical bars 21.

[0022] like Figure 1 As shown, the vertical reinforcement 21 is welded to the outer wall of the pre-embedded sleeve 1, and the welding distance from the lower end of the pre-embedded sleeve 1 upwards is 100mm. The bending position of the vertical reinforcement 21 is located below the opening of the pile hole, and it starts to slope upwards 100mm away from the bottom of the pre-embedded sleeve 1, with an inclination angle of 15-30°, and extends to 100mm above the ground.

[0023] like Figure 1As shown, the upper end of the vertical rib 21 is bent downwards and has a hook 23, which is used to increase the structural strength of the vertical rib 21, prevent the vertical rib 21 from deforming, and improve the shear resistance in the later stage.

[0024] like Figure 1 As shown, the outer wall of the embedded sleeve 1 is provided with a clamp 11 for holding the vertical rib 21, so as to achieve precise positioning between the embedded sleeve 1 and the vertical rib 21, facilitating welding and fixing. The outer wall of the embedded sleeve 1 is provided with an anti-rust coating 12 to improve the anti-rust capability of the embedded sleeve 1.

[0025] like Figure 1 As shown, the concrete pile 3 includes a pile body 31 and a pile head 32. The pile body 31 is cast into the pile hole, and the diameter of the pile head 32 is larger than that of the pile body 31 and is located outside the pile hole. The diameter of the pile head 32 is 250 mm, the height is 150 mm, and the top surface is 50 mm away from the top of the vertical reinforcement 21.

[0026] Therefore, by setting up a reinforcing cage 2 with a trumpet-shaped opening at the top, and extending the reinforcing cage 2 to the outside of the pile hole and located inside the pile head 32, the shear and bending resistance of the concrete pile 3 at the pile head 32 above the ground is improved, and the concrete inside the pile head 32 node forms a whole with limited lateral deformation, thereby improving the structural strength of the concrete pile 3 and preventing cracking and breakage at the pile head 32 position due to strong winds.

[0027] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
