Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The first embodiment is as follows:

as shown in fig. 1-2, the present embodiment provides a concrete pole, which includes a pole body and a base 5; the base 5 is arranged at the bottom of the electric pole body; the electric pole body comprises main steel bars 2, spiral steel bars 3 and a concrete layer 1; the main steel bars 2 are arranged in the concrete layer 1 along the direction of the electric pole body, and the spiral steel bars 3 are arranged in the concrete layer 1 and fixedly connected with the main steel bars 2; six grounding nuts 4 are arranged at the bottom of the electric pole body, and the grounding nuts 4 are in contact with the main steel bars 2 or the spiral steel bars 3; the base 5 through the bolt with the ground nut 4 with the pole body is connected, 5 bottoms of base are provided with earthing pole 6.

The main reinforcing steel bars 2 are connected with the spiral reinforcing steel bars 3 through welding. The grounding nut 4 is connected with the main reinforcing steel bar 2 through welding. The base 5 is an annular base 5, and six bolt holes are formed in the base 5 corresponding to the grounding nuts 4. The bottom of the base 5 is provided with three grounding electrodes 6. The grounding electrode 6 is made of deformed steel.

Through bolted connection between base 5 and the pole body, realized the electricity between base 5 and the pole body simultaneously and be connected to base 5 can play ground connection and prevent the effect that the concrete pole subsides. The bottom of base 5 sets up earthing pole 6, not only can lead to the underground depths with the electric current on the concrete pole, can also increase the area of contact with the soil horizon, further prevents that the concrete pole from subsiding.

Example two:

the present embodiment is an embodiment improved on the basis of the first embodiment.

In the concrete pole in this embodiment, a foam layer is arranged on the inner side wall of the pole body.

In chilly season, the inner wall of the section of burying of concrete pole can freeze, through set up the foam layer on the inside wall at the pole body, the inner wall of concrete pole freezes the back, and the foam layer can form the elasticity buffer zone, prevents that concrete pole from being frost crack.
