Problems solved by technology
The disadvantages of this structure are: first, the structure of the utility pole has no grounding function, and the utility pole is easily shocked by electric shock in a thunderstorm; second, the steel skeleton is not strong enough, thereby reducing the ability of the utility pole to resist wind; There is no positioning device for the measurement circuit on the pole, which will bring trouble to the measurement work after the pole is installed

Embodiment Construction
[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0021] Such as Figure 1 to Figure 7 As shown, the concrete utility pole of this embodiment includes a rod body 1 , and a cavity 11 is arranged axially inside the rod body 1 . The rod body is made of steel bar 2 and concrete, and the steel bar 2 includes a vertical steel bar 21 and a ring bar 22 hooped on the vertical steel bar 21 to form. The ring bar 22 is a spiral hoop on the outer periphery of the ring frame surrounded by the vertical steel bars 21, and the ring bar 22 in this embodiment is a whole bar connected head to tail. At the bottom of the vertical reinforcement 21, an annular metal ring 3 matching the shape of the annular bottom of the rod body 1 is welded, and a metal block 4 is welded on the bottom surface of the annular metal ring 3, and the bottom of the metal block 4 passes through the steel bar 2 in the rod body 1. The prot...

A concrete wire pole comprises a pole body (1) and a chamber (11) arranged axially in the pole body, and is characterized in that the pole body is made from steel bars (2) and concrete; the steel bars(2) are composed of vertical steel bars (21) and ring edges (22) hooped on the vertical steel bars (21); a ring-shaped eyelet (3) corresponding with the bottom ring shape of the pole body (1) is welded to the bottom of the vertical steel bars (21), and the ring-shaped eyelet (3) is welded to metal bars (4). Compared to the prior art, the invention has the beneficial effects that the steel bar frame is more reasonable and stable, the upper pole body bottom is welded with the ring-shaped eyelet, thereby the steel bar frame structure surrounded by vertical steel bars is more stable; further, since the ring-shaped eyelet is welded to metal bars, thereby not only the support area of the pole body bottom is increased, but also the earth terminal of an grounding lead is connected with the grounding lead arranged on in the pole body through the convex column of the ring-shaped eyelet and by the steel bars in the pole body to form the grounding end of the grounding lead.
Description
technical field [0001] The invention relates to an electric pole used for erecting electric wires in the field of electric power, in particular to a cement electric pole. Background technique [0002] There is a Chinese utility model with the patent number CN200620092684.3 titled "A Cement Telephone Pole" which discloses a structure in which the bottom of the telegraph pole is plugged into the water-blocking cover through a socket and sealed by an adhesive layer. seal. Due to the installation of a water-blocking cover at the bottom of the utility pole, it prevents formation water from pouring into the cavity of the utility pole, thereby preventing frost damage at the bottom of the utility pole, prolonging the service life of the utility pole, and preventing collapse due to freezing and thawing . The telegraph pole made by adopting the solution of the utility model is particularly suitable for use in cold areas with high groundwater level, humidity and rain. The disadvanta...
