Adjacent column foot respectively has a ray to be connected by connecting line.
Technical solutions of the utility model further improvement lies in that:Ray is arranged 8, and 8 rays are equal around 45 ° of column foot interval
Even distribution, two rays of corresponding setting pass through the connecting line of straight line and connect on column foot.
Technical solutions of the utility model further improvement lies in that:Ray is arranged 4, and four rays are around 90 ° of column foot interval
Be uniformly distributed, ray includes integrally formed bending segment and extended segment, on adjacent column foot the extended segment of ray be correspondingly arranged and
It is connected by the connecting line of straight line.
Technical solutions of the utility model further improvement lies in that:The bending segment of ray is connect with column foot, the length of bending segment
For degree less than the length of extended segment, the angle between bending segment and extended segment is 135 °.
Technical solutions of the utility model further improvement lies in that:Being grounded extremely galvanized copper stick, zinc-plated copper rod length is
The a diameter of φ 14.5mm of 1.5m.
By adopting the above-described technical solution, the technique effect that the utility model obtains has:
The earthing or grounding means by adjacent column foot of the utility model, should using cascade earthing or grounding means is formed after connecting line connection
Cascade earthing or grounding means disclosure satisfy that the demand for grounding of the transmission tower of high soil resistivity, ensure the water of resistance to thunder of transmission line of electricity
It is flat, and then ensure the safety of transmission line of electricity.
The electric power line pole tower of the utility model cascades earthing or grounding means, simple in structure, easy to implement, can effectively save tower
Material reduces project cost, shortens engineering design, construction period, improves construction efficiency, and there is apparent economic benefit to be imitated with society
Benefit.

Wherein, 1, column foot, 2, ray, 2-1, bending segment, 2-2, extended segment, 3, earthing pole, 4, connecting line.
Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment is described in further details the utility model:
The utility model discloses a kind of electric power line pole towers to cascade earthing or grounding means, this kind of ground structure is particularly suitable for height
The ground connection of the electric power line pole tower of soil resistivity.
Electric power line pole tower described in the utility model cascades earthing or grounding means, be on the basis of existing Contact patch into
Capable improvement, important is the grounded part of adjacent shaft tower is connected to the structure to form cascade ground connection.Transmission line of electricity
Shaft tower is typically provided with four or more column foot.Each column foot is respectively connected with several rays 2, in the end of ray 2
It is fixedly connected with down-set earthing pole 3.Fig. 1, Fig. 2 are the vertical view of the device.Preferentially, earthing pole 3 is set as plating
Zinc-copper stick, zinc-plated copper rod length are usually a diameter of φ 14.5mm of 1.5m.Ray 2 surround 1 center of column foot and is uniformly arranged, phase
Adjacent column foot 1 respectively has a ray 2 to be connected by connecting line 4.The facilities of the ray of column foot are divided to two kinds, so the grade couples
Ground device is also classified into two kinds, and specific embodiment is as follows.
Embodiment 1
Ray 2 is arranged 8 in this embodiment, is uniformly distributed as shown in Figure 1,8 rays 2 are spaced 45 ° around column foot 1.It penetrates
