Description
Technical field
The utility model belongs to communication network grounding system, specifically a kind of intensive earth electrode, be the independent Special grounding system being applicable to computer shield machine room, be also applicable to the independent Special grounding system in the fields such as the limited civil buildings of land area, industrial building, petrochemical industry, finance, telecommunications, medical treatment and military project.
Background technology
In the independent Special grounding system of computer, communication network shielding machine room, because of anti-interference, prevent electromagnetic leakage and require that ground network and earth electrode can not be connected short circuit with the lightning protection of building, power work ground connection and any type of grounding system, and need to keep more than 20m distance with surrounding power consumption equipment, pipeline and road etc., factors brings very large difficulty to burying underground of independent Special grounding network system.
Common ground pole has following several:
One, adopts hot galvanized steel pipe or angle steel as vertical grounding electrode; Earth electrode specification is: DN50, L=2500mm, and the 2.5m that is vertically driven underground is dark, ground connection main line below buried depth 0.7m, is then backfilling and compacted, and often because testing, grounding resistance is defective needs complement earth electrode, extend ground network main line and just can reach grounding resistance requirement, use floor space large.
Its two, ionic earthing array; It is dark to 3m that this earth electrode needs Special punching equipment to hole, and is equipped with around chemical slow release filler filling ionic earthing array, adopts fiery fusion welding to connect copper earth bus.Earthing effect is better, anticorrosive, but cracky, under needing to be embedded in frozen soil layer, sustained release agent has certain pollution to surrounding soil environment, and cost is high, uses floor space less.
Its three, low resistance earthing module; Low resistance earthing module adopts polymer graphite material to be made, and inside is metallic framework, draws splicing ear for the welding of connection ground connection main line outside module.Embedding manner is undertaken by code requirement, and earthing module consumption is more, and cost is higher.Advantage is not corroded, but easy cracked inefficacy, should below frozen soil layer be embedded in, use floor space larger.
Ethiopia's embassy premises new construction that my company undertakes the construction of, concerning security matters Design of Machine Room adopts DN50 hot-dip galvanized steel pipe vertical grounding electrode form, but be 11 Ω according to test after the construction that devises and draw the blueprint, far do not reach the designing requirement value being less than 1 Ω, so complement artificial earthing pole when illustrating that actual measurement is not enough according to drawing, interval 5m complement 3 earth electrodes, test result is 6.5 Ω, still reaches required value far away.As continued complement earth electrode, the ground network of scale like this will expand 2.5 times to 3 times again, and just can be less than 1 Ω, floor space is by intrinsic 10.75m
2be increased to 32.25m
2, material also increases accordingly to be disregarded, and excavation rock is also very difficult, though mechanical equivalent of light excavation improves effect, floor space is again limited, also will ensure the safe distance of independent Special grounding and other Architectural Equipments.So on the basis of original ground network usable floor area, will change design form and the construction technology of ground connection, adopt a kind of reliable method of science, the intensive earth electrode of the utility model produces through the meticulous experimental study of field technician just in this context.
Summary of the invention
The technical problems to be solved in the utility model is to provide the intensive earth electrode that a kind of structure is simple, floor space is little, efficiency of construction is high, construction cost is low, earth resistance is up to standard.

The intensive earth electrode that the utility model provides is centered by hot galvanized steel pipe earth electrode, three zinc-coated flat steel sheet annulus are welded with radial 120 ° of levels each other, do two-layer, upper and lower layer offsets from each other again 60 ° and is made, utilize upper and lower two-layer earth electrode annulus, by earth current to the earth 360 ° of scope water conservancy diversion.
Facts have proved, adopt intensive earth electrode can obtain significant comprehensive benefit: from technical requirement aspect, refresh the mounting means of traditional earth electrode, without prejudice to construction inspection rules, test result is better than other new material earth electrode, and system of laying can prevent electromagnetic leakage; From economic benefit aspect, adopt traditional low-cost material, improve efficiency of construction and construction quality, save a large amount of materials and plant equipment One-Shift Costs; From environmental protection aspect, do not use the material such as chemical resistance-reducing agent, sustained release agent, do not pollute surrounding environment because of soil erosion; From construction aspect, change because test result does not reach designing requirement value and complement earth electrode, operating procedure is simple, guarantees construction schedule, substantially reduces construction period.
