Description
Technical field
This utility model belongs to transmission line of electricity technical field of anticorrosion, particularly relates to a kind of cladded type iron tower foundation for transmission lines portion
Position.
Background technology
Transmission of electricity is after the electric energy sent by electromotor with transformator boosts, then controls equipment access power transmission line through chopper etc.
Road realizes.By version, transmission line of electricity is divided into overhead transmission line and cable run, current China mainly to use still
Overhead transmission line, is to be made up of overhead line structures, wire, insulator, line hardware, bracing wire, pole and tower foundation, grounding device etc.
, and be erected on ground.In recent years, along with the quick growth of national economy, power industry quickly grows, and has promoted whole
The fast development of grid, industry is in fast development period, thus, along with continuing to increase of electric grid investment, to transmission of electricity
The demand of the important component part in line network--iron tower of power transmission line also will be on the increase, the development of iron tower of power transmission line industry
Have a extensive future.
Iron tower of power transmission line, is mainly made up of tower head, tower body, a few major part of tower leg and iron tower foundation position by its structure.
Along with the constantly extension of domestic transmission line of electricity, the etching problem on line steel tower basis becomes increasingly conspicuous.Line steel tower basis due to
It is chronically exposed to field, is easily subject to the impact of various extreme environment so that line steel tower basis is in the presence of a harsh environment by non-
The corrosion of Chang Yanchong.Owing to line steel tower basis is the actual bearer person of power overhead network, in whole circuit, play foundation stone
Effect, directly affect the trouble-free operation of whole piece circuit.Once line steel tower basis is damaged because of corrosion, and circuit will be made to go out
Existing fault, it is impossible to run well, even more so that surrounding enviroment are damaged greatly, threatens the lives and properties peace of the people
Entirely.Particularly expose to the open air at outdoor steel construction, continue to suffer from wind, Exposure to Sunlight, the invasion and attack that drench with rain, be easily corroded, then make moist
The impact of wet air, corrosion condition is the most serious.As connecting portions such as the bolt at iron tower foundation for transmission lines position, nuts.
Although the corrosive environment on line steel tower basis is mainly atmospheric corrosion and soil corrosion.Atmospheric corrosion is primarily referred to as line
The material of road iron tower foundation due to by moisture contained in air, oxygen and some Korrosionsmediums (mainly include sodium chloride,
Carbon dioxide, sulfur dioxide, flue dust, deposit etc.) synergy and by destruction in various degree.Soil corrosion is mainly
Refer to the differently composed composition corrosion in various degree to iron tower foundation material in soil.
But air and soil are extremely complex systems, it is made up of three kinds of materials of different nature of solid-liquid-gas,
Wherein being also contemplated by various microorganisms, these microorganisms rely on soil to survive, and it has life sex character, has new old generation
The function thanked, its metabolic process also will constitute corrosion to the material of iron tower foundation.Add different regions, different gas
Wait, the soil constituent of Various Seasonal is different, and the extent of corrosion caused also is discrepant, additionally, electrical grid is defeated
The high-tension electricity sent, also can ionize ambient air, causes corrosion aggravation.Therefore the corrosion to power transmission line iron tower foundation be one non-
The most complicated problem.
The a lot of anti-corrosion methods in the past used, such as: coating anticorrosive paint, metal spraying, covering cement layer, bottom is rich
The method such as yellow zinc chromate primer paint and protective cover, limited owing to covering the tracing ability of material itself, do not catch up with by external force make that steel part produces flexible,
Bend, deform and chap, affect antiseptic effect and life-span；For the rough steel body surface being corroded, especially
Spot corrosion, gap, nib, it is difficult to well coincide, so that the infiltration of the Korrosionsmedium such as moisture, air, and then anti-corrosion life shortening,
Cause keep the safety in production hidden danger, even servere injury accident.
Therefore, how to carry out the anti-corrosion measure of line steel tower basis, expressed in the industry a lot of concern and also bet the biggest
Energy, is important topic urgently to be resolved hurrily.

Lattice rate.
6) after glass wool cloth and surface felt are fully cured, can be at external coating finish paint, finish paint color can be according to need
Depending on Yaoing.
7) this utility model above-mentioned steps is obtained cladding vaseline cladding anticorrosion iron tower foundation for transmission lines position and carries out reality
Application is considered, and 4 test pieces are individually positioned in protected object iron tower foundation for transmission lines position, and employing embodiment 1 mode will simultaneously
Above-mentioned 4 test pieces protect, and using unprotected steel as comparison, are also positioned at above-mentioned 4 different positions, 24 months
After fetch, from corrosion weight loss calculate corrosion rate.
After 24 months, skin glass silk cloth, have no aging breakage, protective layer is intact.
The computational methods of antiseptic effect:
Corrosion protective efficiency (%)=[(corrosion rate of unprotected test piece)-(corrosion rate of embodiment)] × 100/ is (unprotected
The corrosion rate of test piece)
Seeing table 1, table 1 is the corrosion protective efficiency contrast of this utility model embodiment 1 test piece.
The corrosion protective efficiency contrast of table 1 this utility model embodiment 1 test piece
By the relative analysis of pre-buried test piece Yu unprotected test piece, the bag that this utility model embodiment is provided can be calculated
Covering type iron tower foundation for transmission lines position, its (corrosion protective efficiency) corrosion inhibition rate is more than 99.9%.
Parallel contrast test:
In the same way, the test piece to being only coated with anti-corrosion plaster anti-corrosion belt carries out corrosion protective efficiency test, and corrosion protective efficiency is only
96.7%.
Embodiment 2
The present embodiment is at weak connecting portions such as protected object electric power line steel tower weld seams according to cladding vaseline cladding anti-corrosion method
As a example by the construction of position, this utility model is described in detail:
1) to weak connecting portion deburring, rust such as protected object electric power line steel tower weld seams, surface dirt, water are removed
Divide with oil.
2) at the thing surface to be protected even application anti-corrosion plaster handled well, the composition of anti-corrosion plaster is by weight percentage:
Mineral fat 45%, antirust agent 5%, Liquid Paraffin 30% and calcium carbonate 20%.
3) treat that the weak connecting portions such as protected object electric power line steel tower weld seam are wound around anti-to good through above two-step pretreatment
Erosion band, firmly stretches anti-corrosion belt, overlap joint 50% winding, it is ensured that each part is 2 layers during winding.With hands, anti-corrosion belt surface is comforted
Flat so that it is to be fitted tightly over steel structure surface.
