[0008] The lower end of the steel casing is placed in the center of the small pedestal of the anchor foundation.

[0009] There are three anchor bars, which are placed at 1 / 3 of the bottom circumference of the small pedestal of the anchor bar foundation.

[0010] The anchor hole is 70mm.

[0011] The diameter of the small anchor foundation pedestal is 500mm.

[0012] Pour C30 fine stone concrete into the anchor hole.

[0013] In view of the problems existing in the construction of photovoltaic pile foundations in rocky desertification high and steep slopes with soil and rock combined geology, the inventors designed a photovoltaic pile foundation suitable for rocky desertification high and steep slopes with soil and rock combined geology, which is mainly composed of anchor bars, anchor bar foundation small pedestals and steel casings. The upper end of the steel casing has an adjusting bolt, and the lower end is placed in the anchor bar foundation small pedestal; the anchor bar passes through the bottom of the anchor bar foundation small pedestal, and its upper part is placed in the anchor bar foundation small pedestal, and the lower part is placed in the anchor bar hole; the steel casing is connected to the anchor bars in the anchor bar foundation small pedestal by round steel welding; concrete is poured in the anchor bar hole and the anchor bar foundation small pedestal.

[0014] Compared with the prior art, the utility model has the following outstanding advantages:

[0015] (1) Speed ​​and safety: The photovoltaic pile foundation is constructed with a small handheld drill, with 3 small holes and a hole diameter of 70mm, which has a fast construction speed. In terms of force, the pile head 500 is embedded in the soil layer, ensuring the stability of the foundation, and speed and safety are taken into consideration.

[0016] (2) Strong adaptability: The photovoltaic pile foundation can be built to adapt to the terrain, whether it is flat or has potholes and steep slopes, especially the rocky desertification high steep slopes with soil and rock combined with geology. It is highly adaptable and can be used in various terrain environments.

[0017] (3) It is conducive to improving construction efficiency: After the on-site construction of the photovoltaic pile foundation is completed, the column of the photovoltaic bracket can be adjusted up and down through the adjustment bolts of the embedded steel casing, so as to realize the rapid adjustment of the vertical height of the photovoltaic bracket, facilitate installation, and improve construction efficiency.

[0018] In short, the photovoltaic pile foundation of the utility model has the characteristics of simple and safe structure, wide applicable range, strong applicability according to local conditions, etc. It can be widely used in various terrain environments, not only steep slopes of soil, but also rocky desertification high steep slopes with soil and rock combined geology where conventional foundations are difficult to build.
