Enter underground and be easy the case where being corroded, it is ensured that the security protection of grounding body.
Further, the earth conductor is laid in horizontal, and multiple ground connection collection horizontals is made to be distributed in underground.
Grounding body level is laid in soil resistivity high place by using above-mentioned technical proposal, increases grounded screen
Laying area, convenient for ground resistance is effectively reduced.
Further, the earth conductor is laid with to underground vertical, and multiple ground connection collection sections is made vertically to be distributed in ground
Under.
It, can be by grounding body when one timing of area can be built in the high place of soil resistivity by using above-mentioned technical proposal
It is vertical to be laid with, convenient for ground resistance is effectively reduced.
Further, each adjacent two ground connection on the earth conductor integrates the spacing range between section as 100mm-
250mm makes setting at least five in the length of the every 1m of earth conductor be grounded collection section.
By using above-mentioned technical proposal, ground connection is collected into section concentrated setting, being convenient for multiple ground connection collection section to concentrate reduces centainly
Ground resistance in range, it is ensured that there is good ground connection performance within the scope of this.
Further, the ground connection integrate save be as diameter and length 100mm cylindrical body.
Further, it is the square of 100mm or diameter as the sphere of 100mm that the ground connection, which integrates section as side length,.
Further, the ground connection integrates section as metal, nonmetallic or metal and nonmetallic composite electric conductor.
The embodiment of the present invention has the advantages that
Multiple ground connection are collected section connection composition collection section using one or more earth conductor by collection section formula grounding body of the invention
Formula grounded screen, only need to underground in the horizontal direction or vertical direction opens up a groove, will the distribution of ground connection collection section in the trench, and
By the polyhedral structure of ground connection collection section, make each ground connection collection section that can be in close contact with the soil and individually make in all directions
With the single ground connection collection of reduction saves the contact resistance between surrounding earth medium, is convenient for grounding body in the successional reduction in underground
Surrounding ground resistance makes when the grounded body of thunder energy stream to leak into the earth by continuous diffusing and safely, and structure is simple, is not necessarily to large area
Soil is excavated, manpower and cost are saved.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the collection section formula grounding body of the embodiment of the present invention.
In figure, 1, earth conductor；2, ground connection collection section.
Specific embodiment
The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention..

The erosion resistant coating in outside, wherein inner core setting at least one, and every inner core is made of the conductor wire of sub-thread or multiply, is specifically led
Electric wire is various conductive metals or the composite electric conductor that is made of conductive metal, can also be electrically conductive graphite or is material by graphite
Electric conductor and other non-metal conductors coat the structure of inner core by erosion resistant coating, avoid earth conductor 1 because of long-time embedment ground
Under be easy the case where being corroded, it is ensured that the security protection of grounding body.
The electric conductor of polyhedral structure as described above, ground connection collection section 2 is positive, material can be selected with conductive or semiconductive
The metal of function, nonmetallic or metal and nonmetallic complex, and the size for being grounded collection section 2 is changeable, each face can
Be positive side type or polygon, it is specific preferably for diameter 100mm, the cylindrical body of length 100mm or 100*100*100mm just
The sphere that cube or diameter are 100mm saves 2 polyhedral structure using ground connection collection, equal in all directions convenient for ground connection collection section 2
It can be in close contact with the soil, allow to be effectively reduced the contact resistance between surrounding earth medium.Specifically, earth conductor
1 is laid in pre-buried groove in level, makes multiple ground connection collection sections 2 also in horizontal distribution, and each ground connection collection section 2 is led with ground connection
Body 1 connects and each self-forming is for reducing the isolated node of ground resistance around, and earth conductor 1 is made to be connected to multiple isolated node collection
Close formed can continuity reduce the grounded screen of ground resistance in a certain range, by continuous diffusing when body grounded convenient for thunder energy stream
And the earth is leaked into safely.Wherein at least one is arranged in earth conductor 1, only need to open up in the horizontal direction a groove in underground, will
2 horizontal distributions of ground connection collection section in the trench, excavate soil without large area, effectively save manpower and cost, can also basis
More piece-root grafting earthed conductors 1 are arranged in practical laying condition, and independent assortment is placed in the connection of more piece-root grafting earthed conductors 1, and makes earth conductor 1
On each adjacent two ground connection collection section 2 between spacing range be arranged in 100mm-250mm, it is ensured that every 1m on earth conductor 1
Length range in setting at least five be grounded collection section 2, by will be grounded collection section 2 concentrated settings, convenient for multiple ground connection collection save 2 collect
It is middle to reduce a certain range of ground resistance, it is ensured that there is good ground connection performance within the scope of this.
Embodiment 2
Difference from Example 1 is that earth conductor 1 is laid with to underground vertical, makes multiple ground connection collection sections 2 along Vertical Square
To underground is distributed in, i.e., place high in soil resistivity only need to be in the side of ground lower edge perpendicular to the ground when that can build one timing of area
To a vertical groove is opened up, ground connection is collected into 2 vertical distributions of section in the trench, i.e., convenient for ground resistance is effectively reduced, together
When without large area excavate soil, effectively save manpower and cost.
2 connection of multiple ground connection collection section is formed collection using one or more earth conductor 1 by collection section formula grounding body of the invention
Section formula grounded screen, only need to underground in the horizontal direction or vertical direction opens up a groove, ground connection collection section 2 is distributed in groove
It is interior, be in close contact with the soil each ground connection collection section 2 can in all directions and independent role, reduce single ground connection collection section 2 with
Contact resistance between surrounding earth medium is convenient for grounding body ground resistance around the successional reduction in underground, makes thunder energy
The earth is leaked into when flowing through grounding body by continuous diffusing and safely, structure is simple, excavates soil without large area, save manpower and at
This.
