Intensive ground electrode and installation method

Abstract

The invention belongs to a communication network grounding system, in particular relates to an intensive grounding electrode. The intensive grounding electrode comprises a support, wherein a central vertical post is arranged on the support, lower-layer horizontal supports are uniformly arranged on the same horizontal plane at the side wall of the central vertical post, upper-layer horizontal supports are arranged above the lower-layer horizontal supports, the number of the upper-layer horizontal supports and the number of the lower-layer horizontal supports are both three, the upper-layer horizontal supports and the lower-layer horizontal supports are mutually deviated by 60 degrees, and a grounding electrode round ring is arranged at the other end of each of the upper-layer horizontal supports and the lower-layer horizontal supports. The intensive grounding electrode is suitably used for an independent dedicated grounding system of a computer shielding room, and is also suitably used for independent dedicated grounding systems in the fields such as civil buildings, industrial buildings, petrochemical industry, finance, telecommunications, medical services and war industry with limited land areas. By a laying method of the intensive grounding electrode, electromagnetic leakage can be prevented; materials such as a chemical resistance reduction agent and controlled-release agents are not used, and a surrounding environment cannot be polluted due to water and soil loss; and the operation process is simple, the construction process is ensured, and the construction period is greatly shortened.

Description

Technical field [0001] The invention belongs to a communication network grounding system, in particular an intensive grounding pole, which is an independent dedicated grounding system suitable for computer shielded computer rooms, and is also suitable for civil buildings, industrial buildings, petrochemicals, finance, telecommunications, and medical care with limited land area. And independent dedicated grounding systems in military industry and other fields. The invention also relates to an installation method of the intensive ground electrode. Background technique [0002] In the independent dedicated grounding system of the computer and communication network shielded computer room, due to anti-interference and prevention of electromagnetic leakage, it is required that the grounding grid and the grounding pole cannot be short-circuited with the building’s lightning protection grounding, power supply grounding and any form of grounding system connection, and need Keep a distanc...

Problems solved by technology

[0007] In the new construction of the Ethiopian embassy building undertaken by our company, the design of the confidential computer room adopts the form of DN50 hot-dip galvanized steel pipe vertical grounding electrode, but according to the design blueprint, the test is 11Ω after construction, which is far below the design requirement value of less than 1Ω, so According to the drawing instructions, when the actual measurement is insufficient, artificial grounding electrodes are added, and 3 grounding electrodes are added at an interval of 5m. The test result is 6.5Ω, which is still far from the required value.

If you continue to add grounding electrodes, the grounding network of this scale will have to be expanded by 2.5 to 3 times to reach less than 1Ω, and the floor area will be 10.75m from the original design. 2 increased to 32.25m 2 , the material also increases correspondingly, and it is also very difficult to excavate rocks. Although mechanical excavation improves the efficiency, the occupied area is limited, and a safe distance between the independent dedicated ground and other construction facilities must be ensured.
