[0004] At present, due to improper treatment of the poles and support foundations in collapsible loess areas, the surface soil near the foundation becomes loose or there is a negative terrain with water accumulation. The collapsible loess bearing layer is soaked by water and subsides, seriously affecting the stability of the foundation. Especially the sinking of transmission line poles leads to potential safety hazards that the safe distance between the conductor and the ground is insufficient. Content of the Utility Model

A vertical foundation pile is provided at the top of the concrete layer, and a number of steel bars arranged in a circular pattern are provided in the vertical foundation pile.

[0008] Furthermore, a number of horizontally arranged reinforcing strips are provided on the surface of the steel pile. The reinforcing strips are evenly distributed on the surface of the steel pile, and the included angle between the reinforcing strips is ninety degrees.

[0009] Furthermore, a circular support plate is fixed between the top of the steel pile and the concrete layer, and the connection between the steel pile and the circular support plate is located at the center of the circular support plate.

[0010] Furthermore, a number of steel bars arranged in a square pattern are provided inside the vertical foundation pile, and the bottoms of the a number of steel bars extend into the concrete layer.

[0011] Furthermore, an EVA waterproof board is provided at the bottom of the concrete layer, and the edge of the EVA waterproof board is flush with the concrete layer.

[0012] Furthermore, a number of bosses are fixed at the bottom of the concrete layer, and the bosses pass through the EVA waterproof board and are fixedly connected to the top of the steel pile.

[0013] The reinforced foundation of a substation proposed by the present utility model has the beneficial effects that: through the steel pile and the surrounding reinforcing strips of the present utility model, they can be inserted into the surrounding soil, the steel pile can better bear the pressure and load from all directions, and the transverse and longitudinal cross-arranged reinforcing bars in the concrete layer can make the concrete layer have higher strength.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] Refer to Figures 1-4, A reinforced foundation for a substation, comprising: several steel piles 1 arranged in the soil of the substation foundation. A concrete layer 2 is provided at the top of several of the steel piles 1. Several reinforcing bars 3 arranged horizontally and vertically in a crosswise manner are provided in the concrete layer 2. A vertical foundation pile 4 is provided at the top of the concrete layer 2, and several steel bars 5 arranged in a circular pattern are provided in the vertical foundation pile 4. The reinforced foundation can insert the steel piles 1 and the surrounding reinforcing bars 6 into the surrounding soil. The steel piles 1 can better bear the pressure and load from all directions, and the reinforcing bars 3 arranged horizontally and vertically in a crosswise manner in the concrete layer 2 can make the concrete layer 2 have higher strength. By providing the vertical foundation pile 4 with steel bars 8 and steel bars 5, the transmission poles of the substation can be effectively prevented from collapsing, and the service life of the substation is improved.

[0021] In this embodiment, several horizontally arranged reinforcing bars 6 are provided on the surface of the steel pile 1. The reinforcing bars 6 are evenly distributed on the surface of the steel pile 1, and the included angle between the reinforcing bars 6 is ninety degrees. The reinforcing bars 6 around the steel pile 1 can be inserted into the surrounding soil. In this way, the steel pile 1 can better bear the pressure and load from all directions, thereby ensuring its reliability and safety in practical applications.

[0022] Furthermore, a circular support plate 7 is fixed between the top of the steel pile 1 and the concrete layer 2, and the connection between the steel pile 1 and the circular support plate 7 is located at the center position of the circular support plate 7. By installing a circular support plate 7 at the top of the steel pile 1, the load can be effectively dispersed and transmitted, reducing the stress concentration phenomenon, thereby enhancing the stability of the overall structure.

[0023] Furthermore, several square-arranged steel bars 8 are provided inside the vertical foundation pile 4. The bottoms of several of the steel bars 8 extend into the concrete layer 2. The steel bars 8 can significantly enhance the strength and stability of the vertical foundation pile 4.

[0024] In addition, an EVA waterproof board 9 is provided at the bottom of the concrete layer 2, and the edge of the EVA waterproof board 9 is flush with the concrete layer 2. The EVA waterproof board 9 can effectively isolate the water penetration between the soil layer and the concrete layer, thereby enhancing the waterproof ability of the foundation.

[0025] It should be noted that several bosses 10 are fixed at the bottom of the concrete layer 2. The bosses 10 pass through the EVA waterproof board 9 and are fixedly connected to the top of the steel pile 1. The bosses 10 can effectively connect the concrete layer 2 and the steel pile 1, ensuring that the steel pile 1 can be firmly installed at the bottom of the concrete layer 2.

[0026] Working mode: The staff inserts the steel pile 1 into the soil and pours a concrete layer 2 at the top. The reinforcing bars 6 around the steel pile 1 can be inserted into the surrounding soil, which can better bear the pressure and load from all directions. A circular support plate 7 is installed at the top of the steel pile 1, which can effectively disperse and transfer the load and reduce the stress concentration phenomenon. The vertical foundation pile 4 provided with steel bars 8 and steel strips 5 can effectively prevent the transmission poles of the substation from collapsing.

[0027] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
