Due to the improvement of lighting requirements and the concern for energy consumption, the forms of street lamps are becoming increasingly diverse, and at the same time, the requirements for safety are also continuously increasing. These changes pose higher requirements for street lamp foundations, and they need to have higher stability and reliability to cope with the changing lighting requirements and safety challenges.

[0003] The cast-in-place concrete foundation used in traditional street lamps has low construction efficiency, and it is difficult to guarantee the appearance and quality. When using a prefabricated ordinary concrete foundation, facing the wind and rain year after year, it has high requirements for strength and durability. The strength and durability of traditional ordinary concrete bases are poor, and it is inconvenient to replace. Therefore, it is necessary to improve the existing manufacturing technology of ordinary concrete street lamp bases. Summary of the Invention

It can adapt to various diameters of street lamp poles, and the entire base and street lamp pole are easy to replace.

[0005] To meet the above situation, the utility model is realized through the following technical solutions:

[0006] A prefabricated UHPC street lamp base with an adjustable installation aperture for a street lamp pole, comprising a perforated plate made of UHPC and a UHPC frustum matrix. Four corners of the UHPC plate are provided with an opening for connecting and fixing with existing bolts on the ground through nuts. Two openings are reserved in the center of the UHPC plate for the passage of wires. A second opening is provided in the UHPC frustum matrix, and it is adjusted by a bolt with a cap to adapt to street lamp poles of different diameters.

[0007] The principle of the utility model is: in the case of an existing embedded foundation with bolts on the urban road, the UHPC base is fixed on the ground through bolts and nuts, and finally the street lamp pole is installed.

[0008] The characteristics of the device of the utility model are: the basic main structure of the scheme is made of UHPC material, and the four corners of the UHPC perforated plate at the bottom are designed to have an opening for fixing to the ground, and the upper and lower middle parts of the UHPC truncated cone base are respectively provided with four threaded steel sleeves that pass through the UHPC truncated cone base through cap bolts to adapt to the installation of street light poles with different diameters.

[0009] Furthermore, the perforated plate made of UHPC is provided with one opening and two openings, wherein the one opening is distributed at the four corners of the UHPC plate and serves to be anchored with bolts reserved on the ground, and the second opening is distributed at the center of the UHPC plate and can be used for line arrangement of street lamps.

[0010] Furthermore, the UHPC truncated cone base has a hollow truncated cone structure, which is provided with a first opening and a second opening. The number of the first opening is one, which is distributed in the center of the UHPC truncated cone base and is used to install a street light pole. The number of the second openings is eight, which are distributed in the upper and middle lower parts of the UHPC truncated cone base.

[0011] Furthermore, a threaded steel sleeve is embedded in the second opening of the UHPC truncated cone base, and its function is to adapt to the installation of street light poles with different diameters by screwing in a cap bolt.

[0012] The UHPC street lamp base is a UHPC prefabricated base, and the perforated plate 1, UHPC truncated cone base 2, and threaded steel sleeve 3 made of UHPC are prefabricated using a one-time casting process. BRIEF DESCRIPTION OF THE DRAWINGS
