[0002] At present, there are many types of poles on urban roads in China. They are not only single-function and wasteful of resources, but also scattered and affect the city environment. In order to adapt to the development needs of urban energy conservation, beautification and resource sharing, a road multi-pole integration method has been derived, which integrates the functions of municipal lighting, traffic signs, road monitoring, traffic signals, communication base stations, environmental protection detection, etc. in the city, also known as integrated poles. Since the number and size of poles suspended on the integrated poles are different, the forces on the integrated poles are different. In order to ensure the stability of the integrated poles, it is not economical to use the largest foundation as the foundation of the integrated poles and the land is limited; to determine a unique foundation for each integrated pole, the construction site needs to formulate multiple foundation templates according to the size of the foundation, resulting in waste of resources and extended construction period.
[0003] Therefore, for the integrated pole that suspends various types of rods, how to find an economical and efficient integrated pole foundation form under the premise of ensuring the stress stability and safety of the integrated pole is an urgent problem to be solved. Utility Model Content

[0029] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, an assembled integrated pole foundation comprises an integrated pole foundation basic body module, a standard block module and a connecting piece;
[0031] The basic module of the integrated pole foundation includes the basic body 1 of the integrated pole foundation. The basic body 1 of the integrated pole foundation is prefabricated with C30 concrete and is in the shape of a cuboid. Its length, width and height are 1m, 1m and 1.5m respectively. During the prefabrication process, a large lifting lug 4, a flange steel bar 2 and a flange chassis 3 are embedded on the top. The flange steel bar 2 and the flange chassis 3 are located at the center of the basic body 1 of the integrated pole foundation. The threaded part of the flange steel bar 2 extends out of the basic body 1 of the integrated pole foundation by about 0.11m, which is convenient for the later connection with the municipal integrated pole. The lower end of the flange steel bar 2 is provided with a bending structure to improve its pull-out resistance. The large lifting lug 4 is embedded on both sides of the top of the basic body 1 of the integrated pole foundation, which is convenient for lifting and transportation. The sides of the basic body 1 of the integrated pole foundation are penetrated by power pipes 10 and connection holes 8. The power pipes 10 are used to insert the transmission lines. Eight connection holes 8 are set on each side and correspond to the standard block 5. Wedge-shaped shear keys 7 are set around the lower part of the basic body 1 of the integrated pole foundation, and four are set on each side.
[0032] The standard block module includes a standard block 5, which is prefabricated with C30 concrete and is in the shape of a cuboid, with a length, width and height of 0.5m, 0.5m and 0.8m respectively. When prefabricated, a small lifting lug 6 is embedded on the top, and a wedge-shaped shear key 7, a wedge-shaped shear key hole 9 and a connecting hole 8 are set on the side. Two wedge-shaped shear keys 7 are set on two adjacent sides of the standard block 5, and two wedge-shaped shear key holes 9 are set on the other two adjacent sides of the standard block 5. The wedge-shaped shear key holes 9 are used to adapt to the wedge-shaped shear keys 7 on the standard block 5 and the basic body 1 of the integrated pole foundation, and the positions are set correspondingly. The connecting holes 8 are respectively set at the four corner points of the side of the standard block 5, and it is ensured that no intersection occurs.
[0033] The connecting parts include threaded steel bars 11, nuts 12, gaskets, and waterproof caps 13. The threaded steel bars 11 pass through the connection holes 8 of the integrated pole foundation basic body 1 and the standard blocks 5, and are compressed on both sides by gaskets and nuts 12. The waterproof caps 13 are arranged on the outer end faces of the connection holes 8 to prevent external rainwater from entering the holes. The side of each integrated pole foundation basic body 1 can be fixedly connected to two standard blocks 5. At this time, the two wedge-shaped shear keys 7 on the integrated pole foundation basic body 1 are embedded in the two wedge-shaped shear key holes 9 on the side of the standard block 5, and the side wedge-shaped shear key holes 9 of the two adjacent standard blocks 5 are matched with the wedge-shaped shear keys 7. A maximum of eight standard blocks 5 can be connected to the four sides. In the structure after the connection is completed, the bending moment is transmitted through the threaded steel bars 11 arranged up and down, and the shear force is transmitted through the wedge-shaped shear keys 7 to ensure its overall structural strength.
[0034] Working principle: Since a variety of rods are hung on the vertical uprights of the integrated pole at the same time, and the number and direction of the hanging rods of the integrated pole at different positions are different, the utility model prefabricates the basic body 1 of the integrated pole foundation and the standard block 5 in the project, and effectively connects the basic body module of the integrated pole foundation with the standard body module through connecting parts. At the same time, by adjusting the number and layout of the standard bodies, the size and form of the foundation can be effectively changed, so as to adapt to the force requirements of different integrated poles.
