AI Technical Summary
During installation, existing prefabricated street light helical piles are prone to misalignment at the top due to feeding errors, which affects the verticality of the bracket and the street light, thus impacting the assembly effect.
The structure employs a threaded rod and a rotating disk. By adjusting the distance between the rotating disk and the welding plate, the feed error of the threaded rod is eliminated, thus achieving leveling of the bracket. The vertical installation of the street light is ensured through the limit groove and bubble leveling structure.
This improved the installation effect of the bracket, reduced the verticality error of the street light, and ensured the verticality and assembly quality of the street light.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of street light spiral pile technology, and in particular to a prefabricated street light spiral pile structure. Background Technology
[0002] Prefabricated street light helical pile structure is a type of pile used in street light installation. It combines the advantages of prefabricated construction and helical piles, providing an efficient and environmentally friendly solution for fixing street lights. In order to improve the wind resistance of prefabricated street light helical pile structure, some existing prefabricated street light helical pile structures adopt a multi-pile ground gripping form to provide better wind resistance for street lights.
[0003] During assembly, multiple spiral piles are first driven into the ground using a drilling rig. Then, bolts are used to install the bracket on the upper end of the spiral piles. Finally, bolts are used to install the street light on the surface of the bracket, thus providing good wind resistance for the street light by using multiple spiral piles embedded in the ground.
[0004] When multiple helical piles are driven into the soil using a drilling rig, feed errors can easily occur, making it difficult to ensure that the upper ends of the multiple helical piles are on the same horizontal plane. This can lead to installation deviations during bracket installation, affecting the verticality of the street light installation and the overall assembly effect. Utility Model Content

[0021] In this embodiment, the auger base 35 is first installed on the output end of the drilling rig using bolts. Then, the drilling rig rotates the auger 36 into the soil. Multiple augers 36 are driven into the soil in this manner. Next, the bracket 1 is placed above the auger base 35, aligning the connecting plate 34 with the auger base 35. When multiple auger bases 35 are not on the same horizontal plane, the threaded rod 32 is rotated, causing a change in the distance between the rotating plate 33, the connecting plate 34, and the welding plate 31. Simultaneously, the limiting plate 37 moves against the surface of the welding plate 31. The bracket 1 can be leveled by sliding. After leveling, the user rotates the connecting plate 34 to align the holes of the connecting plate 34 with the holes of the spiral rod base 35.
