[0024] The utility model is further described below in combination with the drawings and examples. The examples described below by referring to the drawings are exemplary and are only used for explaining the utility model and cannot be understood as the limitation of the utility model.

[0025] As shown in the accompanying drawings, Figures 1-4As shown, a prefabricated fence installation foundation comprises a compacted soil layer 1, the top surface of which is provided with a plurality of connecting beams 2, which are evenly distributed along the length direction thereof; the two end surfaces of each connecting beam 2 are provided with upper and lower through limiting grooves 21, and a foundation pile 3 is clamped in each limiting groove 21, which is perpendicular to the horizontal plane and has its lower part embedded in the compacted soil layer 1; the foundation piles 3 in the two limiting grooves 21 of the two connecting beams 2 that are adjacent to each other and have opposite openings are the same foundation pile 3, and the groove walls of the two limiting grooves 21 that are adjacent to each other and have opposite openings are matched and clamped on the outside of the foundation pile 3; a stand 4 is arranged on the foundation pile 3, the lower part of which is pre-buried and cast in the foundation pile 3, and the stand 4 protrudes upward from the foundation pile 3.

[0026] The connecting beams 2 and the foundation piles 3 are both prefabricated reinforced concrete structures, which are transported to the construction site after being prefabricated in the factory. During the on-site construction of the fence, the soil in the construction area is compacted by a compactor after the site is leveled to form a compacted soil layer 1, and the top surface of the compacted soil layer 1 is parallel to the horizontal plane. Then, the positions of the connecting beams 2 and the foundation piles 3 in the horizontal direction are marked by lines, and the foundation piles 3 are embedded in the compacted soil layer 1 to the specified depth, and then a plurality of connecting beams 2 and foundation piles 3 are assembled into an integral structure according to requirements. After the connecting beams 2 and the foundation piles 3 are assembled, the groove walls of the two limiting grooves 21 that are adjacent to each other and have opposite openings are matched and clamped on the outside of the foundation pile 21 to position the foundation pile 3 in the horizontal direction, that is, the bottom walls of the two limiting grooves 21 support the foundation pile 3 and clamp and position the foundation pile 3 in the horizontal direction parallel to the connecting beams 2, and the two side groove walls arranged at intervals support the foundation pile 3 and clamp and position the foundation pile 3 in the horizontal direction perpendicular to the connecting beams 2. At the same time, the two foundation piles 3 that are adjacent to each other also clamp and position the connecting beams 2 between them in the horizontal direction. Finally, the two ends of the flexible net, the rigid fence or the fence plate are fixedly installed on the stand 4 according to requirements, wherein the bottom surface of the rigid fence or the fence plate is supported by the connecting beams 2, and the fence construction is completed. The foundation pile 3 can be directly driven into the soil layer, or a pile hole can be dug first, and then the lower part of the foundation pile 3 is embedded in the pile hole.

[0027] The application sets the compacted soil layer 1 to support and ensure the parallelism of the tie beam 2 to the horizontal plane, and also sets the tie beam 2 with the limiting through slot 21 at both ends to connect and support two adjacent base piles 3, so that the upper part of one base pile 3 is supported and positioned in the horizontal direction by the slot wall of the limiting through slot 21 on the two sides of the tie beam 2, and similarly, one tie beam 2 is also positioned in the horizontal direction by the base piles 3 at both ends, the tie beam 2 is clamped and supported with the base piles 3 through the limiting through slot 21 to form an integral structure, thereby improving the installation stability of the base piles 3 and the tie beam 2, further improving the stability of the whole fence installation foundation, and improving the wind resistance of the fence structure installed on the stand column 4. The tie beam 2 and the base pile 3 in the application are clamped and connected, the assembly process is simple, convenient to disassemble and recycle, saves manpower, and is green and environmentally friendly.

[0028] The compacted soil layer 1 is used to support the tie beam 2 and ensure that the tie beam 2 is parallel to the horizontal plane, and is also used to bury and fix the base pile 3, so as to ensure that the base pile 3 is fixed and perpendicular to the horizontal plane, therefore, the top surface and the bottom surface of the compacted soil layer 1 are required to be parallel to the horizontal plane. The tie beam 2 is used to connect and support two base piles 3 at both ends, and two adjacent tie beams 2 are used to position the base piles 3 therebetween in the horizontal direction, the limiting through slot 21 cooperates with the base pile 3 to clamp and connect the tie beam 2 and the base pile 3, thereby achieving the mutual locking and positioning of the two in the horizontal direction, and improving the installation stability of the base pile 3. The top surface and the bottom surface of the tie beam 2 can be curved surfaces or flat surfaces. Preferably, the top surface and the bottom surface of the tie beam 2 are both flat surfaces and parallel to each other, which facilitates the positioning of the tie beam 2 and also facilitates the support of the subsequent installed fence.

[0029] The two adjacent tie beams 2 can be arranged at intervals or adjacent to each other. Preferably, the two adjacent tie beams 2 are arranged adjacent to each other, and the slot walls of the two limiting through slots 21 of the same base pile 3 enclose a limiting through hole. The end surfaces of the two adjacent tie beams 2 abut each other, further improving the integrity and reliability of the whole fence installation foundation, and ensuring that the tie beam 2 more stably supports the base pile 3.

[0030] The limiting through slot 21 on the tie beam 2 can be a U-shaped slot, a V-shaped slot or a circular arc-shaped slot, etc. The cross section of the base pile 3 can be a circular structure, a rectangular structure, an elliptical structure, a regular hexagonal structure, etc. As a further preferred, the cross section of the limiting through hole and the shape and size of the cross section of the base pile 3 are the same, and there is no gap between the slot wall of the limiting through slot 21 and the side wall of the base pile 3, two adjacent tie beams 2 clamp and position the base pile 3, further improving the connection reliability of the tie beam 2 and the base pile 3. As a further preferred, the cross section of the base pile 3 is a circular structure, the limiting through hole is a circular through hole, and the cross section of the limiting through slot 21 is a circular arc segment with a central angle of 180°, which is simple in structure and facilitates the casting and forming of the base pile 3 and the tie beam 2.

[0031] The upper end of the pile 3 can protrude above the top surface of the tie beam 2 or be below the top surface of the tie beam 2. Preferably, the top surface of the pile 3 is flush with the top surface of the tie beam 2, and the upper end and the lower end of the side surface of the pile 3 are both supported and fixed, further improving the stability of the pile 3.

[0032] The column 4 can be a solid column structure or a hollow cylinder structure, and can be made of a steel pipe, an I-beam or a channel steel section, or can be casted by reinforced concrete. The cross-sectional contour of the column 4 can be circular, rectangular or hexagonal. Preferably, the column 4 is a steel pipe structure with a circular cross-sectional contour, which is light in weight and excellent in mechanical properties, and is convenient to process and manufacture.

[0033] Because the lower part of the column 4 is pre-embedded and casted in the pile 3, the combined structure of the two has a large length and cannot be disassembled, which is inconvenient to carry. Preferably, the pile 3 is provided with a socket with an axis arranged in the up-down direction, and the hole diameter of the socket is greater than the outer diameter of the column 4; the lower part of the column 4 is inserted into the socket, and the socket is filled and casted with grouting material to fixedly connect the column 4 and the pile 3. The pile 3 and the column 4 pre-fabricated in the factory are two independent components that are not connected to each other, which is convenient to carry. After the tie beam 2 and the pile 3 are installed at the construction site, the lower part of the column 4 is inserted into the socket and grouting material is filled and casted into the socket to cast the column 4 and the pile 3 as a whole structure, avoiding the column 4 from shaking in the socket and ensuring the stability of the column 4. The column 4 and the pile 3 can also be fixedly connected by filling and casting concrete in the socket. However, the gap between the socket and the column 4 is generally about 2mm, which is small, but the concrete particles are large and are not convenient to fill and cast, so the grouting material with finer particles is selected, which is easier to fill and cast into the gap between the column 4 and the socket. Generally, the height of the pile 3 is about 300mm, and the depth of the column 4 inserted into the pile 3 is preferably more than two-thirds of the total height of the pile 3.

[0034] When the fence mounting base is arranged in an area with large environmental temperature difference, the connecting beam 2 and the foundation pile 3 of the reinforced concrete structure will expand and contract with the environmental temperature, and then the volume of the connecting beam 2 and the foundation pile 3 will change greatly. If the connecting beam 2 and the foundation pile 3 are tightly attached to each other when initially installed, the connecting beam 2 and the foundation pile 3 will extrude each other and damage the overall structure when the environmental temperature rises and the volume increases, and the connecting beam 2 and the foundation pile 3 will move away from each other and generate a gap when the environmental temperature drops and the volume decreases, which will damage the stability of the overall structure. Preferably, the elastic pad 5 is arranged between the slot wall of the limiting through slot 21 and the side wall of the foundation pile 3. When the volume of the connecting beam 2 and the foundation pile 3 increases, the elastic pad 5 is extruded, so as to avoid rigid extrusion and damage of the connecting beam 2 and the foundation pile 3, and improve the service life of the connecting beam 2 and the foundation pile 3. When the volume of the connecting beam 2 and the foundation pile 3 decreases, the elastic pad 5 fills the gap between the slot wall of the limiting through slot 21 and the side wall of the foundation pile 3, so as to ensure the assembly stability of the connecting beam 2 and the foundation pile 3. The elastic pad 5 can be a rubber pad structure, or a combined structure of a steel plate and a plurality of compression springs, the compression spring is perpendicular to the steel plate and one end of the compression spring is connected to the steel plate, and the compression direction of the compression spring is perpendicular to the side wall of the foundation pile 3. As a further preferred embodiment, the elastic pad 5 is a rubber pad structure, which is simple in structure and convenient to process and manufacture. The rubber pad can be made of polyurethane rubber, natural rubber or styrene-butadiene rubber.

[0035] The embodiments of the specific implementation are the preferred embodiments of the utility model, and do not limit the protection scope of the utility model, so that: equivalent changes made according to the structure, shape and principle of the utility model should be covered in the protection scope of the utility model.
