Abstract
The invention discloses a plasma ground rod vertical installation method. The method is characterized by including the construction steps that first, a hole which is 3.5m in depth and 15cm in width is vertically drilled in the ground with a well drill, wherein the excavated area is 0.07m<2>; second, the hole is filled with backfill bentonite with the height of about 20cm; third, a container is filled with 50Kg of water and 0.2Kg of initiating agent, the water and the initiating agent are stirred till the initiating agent is completely dissolved, 0.5Kg of filler is added into the container, and the mixture is stirred to be pasty and then poured into a breathing hole in a ground rod till the height of the mixture reaches 30cm; fourth, the plasma ground rod is vertically placed into the hole and lifted upwards and downwards for several times to make full contact with the filler till the rest of the filler reaches the position with a distance of 100mm to the top end of the ground rod; fifth, the ground resistance of the buried plasma ground rod is measured; sixth, a 95mm<2> cable braid formed by braiding a plurality of strands of copper wires and a plasma ground rod wire are welded. The method has the advantages that the occupied area is small, construction difficulty is low, resistance to corrosion is strong, resistance reducing effects are durable and stable, service life is long, and installation cost is reduced.
Description
Technical field
The present invention relates to the electrical construction technical field, relate in particular to a kind of plasma earth rod at right angle setting method.Being applicable to high soil resistivity, dry soil condition, site condition has in limited time, is particularly useful for all kinds of higher grounding requirements, place that the earth work difficulty is larger.
Background technology
At present, in the various grounding system installing engineerings of metallurgy industry, traditional grounding system mounting means drawback comes out gradually.In tradition grounding system installation process, adopt large-scale excavating equipment to be excavated and backfill, excavated area at least reaches 1m
2, so not only drop in a large number the expense of plant equipment, and destroyed the conductivity of original soil in mining process.Plasma earth rod at right angle setting method has not only been saved the Meteorological of excavating equipment, and has reduced the destruction of original soil conductivity.
Summary of the invention
Purpose of the present invention is exactly the shortcoming existed for prior art, a kind of plasma earth rod at right angle setting method is provided, improve metallurgy industry electric device grounding system resistance to corrosion and useful life, solve the shortage of land resource problem, improve installation efficiency, reduce installation cost and guarantee the construction period.
The object of the present invention is achieved like this: a kind of plasma earth rod at right angle setting method is characterized in that: by following construction procedure, undertaken:
1, adopt trepan getting into the cave of 3.5 meters of the vertical drill degree of depth, 15 centimetres of width earthward, excavated area 0.07m in the construction site of having chosen
2.
2, insert high about 20cm backfill bentonite in getting into the cave, allow the electrolyte flow of infiltration at the bottom of hole.
3, preparation filler, in being greater than the container of 150 liters, volume puts into 50Kg water, the supporting initator 0.2Kg provided of plasma earth rod is provided, be stirred to whole dissolvings, the supporting filler 0.5Kg provided of plasma earth rod is provided, be stirred to pasty state, inject in the spiracle on the plasma earth rod and reach 30 centimetres high.
4, bury the plasma earth rod, take the plasma earth rod of 3 meters of length apart two end sealant tapes, vertically put into the hole of digging, carry up and down and allow several times the plasma earth rod fully contact with filler.Only, cover head protector while filling out around the plasma earth rod to plasma earth rod top 100mm by all the other fillers.Spiracle on the plasma earth rod must not be stopped up by earth or filler, and the head protector upper vent hole, on backfill soil, must not stop up, and places inspection well, allows necessary air and aqueous vapor to enter.
5, measurement of Grounding Resistance, the earth resistance of the plasma earth rod that measurement is buried.When a set of plasma earth rod does not reach the ground resistance requirement, available two covers or a few cover are in parallel to be used, and the interval between rod and rod should be greater than 5m.
6, welding plasma earth rod wire, use exothermic welding method at the heat release pad, the cable pigtail that the 95mm2 strand copper wire is weaved into and plasma earth rod wire bonds.
Compared with prior art, advantage of the present invention is: floor space is little, difficulty of construction is low, resistance to corrosion is strong, resistance reducing effect lasting stability, long service life, reduces installation cost.

In figure: 1, electrolyte 2, backfill bentonite 3, filler 4, plasma earth rod 5, cable pigtail 6, heat release pad 7, plasma earth rod wire 8, spiracle 9, the inspection well of infiltration.
Embodiment
For further describing the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described.
As shown in the figure, a kind of plasma earth rod at right angle setting method is characterized in that: by following construction procedure, undertaken:
1, adopt trepan getting into the cave of 3.5 meters of the vertical drill degree of depth, 15 centimetres of width earthward, excavated area 0.07m in the construction site of having chosen
2.
2, insert high about 20cm backfill bentonite 2 in getting into the cave, allow the infiltration electrolyte 1 flow to hole at the bottom of.
3, preparation filler 3, in being greater than the container of 150 liters, volume puts into 50Kg water, the supporting initator 0.2Kg provided of plasma earth rod is provided, be stirred to whole dissolvings, the supporting filler 0.5Kg provided of plasma earth rod is provided, be stirred to pasty state, inject in the spiracle 8 on plasma earth rod 4 and reach 30 centimetres high.
4, bury plasma earth rod 4, take the plasma earth rod 4 of 3 meters of length apart two end sealant tapes, vertically put into the hole of digging, carry up and down and allow several times plasma earth rod 4 fully contact with filler.By all the other fillers 3 fill out around plasma earth rod 4 during to plasma earth rod 4 top 100mm only, cover head protector.Spiracle 8 on plasma earth rod 4 must not be stopped up by earth or filler 3, and the head protector upper vent hole, on backfill soil, must not stop up, and places inspection well 9, allows necessary air and aqueous vapor to enter.
