Description
Technical field
The utility model relates to the damaged cement pole of power transmission and transformation and repairs field, particularly the damaged cement pole tempering of a kind of power transmission and transformation fiber reinforced structure.
Background technology
The transmission line of electricity now run, transformer station's great majority are due to longer at the operation time limit, power transmission and transformation cement pole there will be crackle, de-husky, fall block, the phenomenons such as strong are lost on surface, in this case, in order to not affect, grid equipment is continuous, safe operation, maintenance and reinforcement must be carried out, otherwise will the well damage of cement pole be caused, cause grid power blackout accident.For many years, means never suitable in power transmission and transformation cement pole maintenance and reinforcement, repair and become a difficult problem.
Utility model content
The purpose of this utility model is the reparation in order to realize the damaged cement pole breakage of power transmission and transformation, and spy provides the fiber reinforced structure of the damaged cement pole tempering of a kind of power transmission and transformation.
The utility model provides the fiber reinforced structure of the damaged cement pole tempering of a kind of power transmission and transformation, it is characterized in that: the fiber reinforced structure of the damaged cement pole tempering of described power transmission and transformation, employing tempering is fiber reinforced, completes reparation to local damage cement pole (1) by adhesive linkage (2) and glass fabric layer (3);
The curing compound of epoxy resin: select low poisonous agent, adopts wet-cured type epoxy curing agent to wet base;
Glass fabric: select the non-twist plain weave woven roving of middle alkali in anticorrosion reinforcing construction;
The quality index of epoxy resin: epoxy resin is that a class applies general synthetic resin, and it has excellent adhesive property, preferably heat-resisting and decay resistance, the features such as cure shrinkage is low, processing performance is good; Mainly be applicable to the medium that corrosivity is not too strong, alkaline resistance properties is more outstanding, also general acid (except the hydrofluoric acid) corrosion of ability; The main feature of epoxy resin is: adhesive strength is high, and shrinkage factor is low; The resin serviceability temperature of normal temperature cure is no more than 80 DEG C;
Conventional product: E-44(6101), E-42(634) and E-51(618);
Inserts: fines, coarse aggregate are referred to as inserts, fines, the coarse aggregate of preparation resin mortar adopt quartz sand, and acid resistance is not less than 95 ﹪, and moisture content is not more than 1%, and mud content is not more than 1%;
The preparation of A, epoxy resin sizing material
By attenuant and be preheating to the epoxy resin of 40 DEG C, needed amount takes and adds in container, after stirring, is chilled to room temperature stand-by; Take quantitative resin during use, add curing compound and stir and namely make epoxy resin sizing material; During formulate glass steel back cover material, before not adding curing compound, add some thinners again;
The preparation of B, epoxy resin daub
Epoxy resin sizing material, adds powder after stirring, then stirs, and is just mixed with clay;
The preparation of C, epoxy resin mortar
Epoxy resin sizing material, with addition of entering fines, coarse aggregate after stirring, then stirring, being mixed with mortar;
D, points for attention
The effect of resin and curing compound is exothermic reaction, the excessive not easy heat radiation of amount of preparation, at every turn fixed according to construction speed, is used while allocating, at initial setting time, is finished in 40 minutes;
Curing compound impouring is stirred simultaneously, and simultaneously mixer is put into cold water and cooled, and prevents hot-spot from solidifying;
The ethylenediamine curing compound selecting toxicity larger, uses after ethylenediamine and acetone 1:1 in advance wiring solution-forming.
The technique of the fiber reinforced structure of the damaged cement pole tempering of described power transmission and transformation, adopt manual pasting forming process, its each operation and broad outlines are:
The first step, back cover; Dip in back cover material with hairbrush, cylinder and carry out secondary bottom sealing in basic unit, period spontaneous curing more than 24 hours; Back cover thickness more than 0.4mm, should must not have the phenomenon such as trickling, bubble;
Second step, scrape clay repair; To cave between substrate surface or aspect out-of-flatness place, clay need be scraped with scraper, be filled and led up repairing, after 24 hours, paste glass fabric again; Clay thickness is no more than 1 millimeter, otherwise there will be full of cracks;
3rd step, sticking glass cloth; The stickup order of glass fabric: from top to bottom, its overlap joint acts in accordance with Flow of Goods and Materials direction to cement pole, and lap width is generally not less than 50mm, and each layer droops seam and should stagger mutually; During paving, glass fabric reaches smooth;
4th step, select continuity method to construct according to this process characteristic method of attaching, its method is:
Dip in after upper sizing material brushes one times with hairbrush, paste first floor glass fabric immediately, and with scraper plate or hairbrush, glass fabric is tight compact, extrude bubble and unnecessary sizing material; After repairing to be checked is qualified, sizing material solidification is not waited namely to paste continuously by same method, until reach the number of plies of designing requirement; Every cloth should divide 2/3 width pinning each cloth of last layer.
The common deficiency of the fiber reinforced structure of the damaged cement pole tempering of described power transmission and transformation and prevention and controls: the first: resin infiltration is bad, interlayer turns white, the non-phenomenon of osmosis of the resin such as white tiles, white point is seen on surface, touches with hammer the sound cover plate template width deviation can recognizing bond not labor, layering:
Contaminated glass fabric acetone, alcohol dry after cleaning, and glass yardage roll is placed in drying, dust-proof storehouse, forbids there is wrinkle;
Construction environment relative humidity should not be greater than 80%, in case interlayer makes moist, dust-proof working should be carried out in job site;
Resin, from adding curing compound, was finished in 40 minutes;
Must not holiday, leak and scrape, leak pressure, be coated with thin, glass fabric eyelet is fully infiltrated at visual angle, is combined into entirety with glass;
The second: the shelling of glass fiber reinforced plastic hollowing, gauffer, interlayer have bubble:
Basic unit's negative and positive angle place first tries to spread glass fabric, brush resin paving again after suitable, and these positions should not take continuous paving method to construct; As found foaming in construction, when being difficult to get rid of, with pocket knife, bubble is scratched pressing, resin and glass fabric are recombined, to the bubble found after resin solidification, scratches along bubble periphery with pocket knife, remove part of flaking, with wood file or emery cloth hacking, after cleaning, brush coating is repaired again;
The third: resin solidification solidifies slowly or not, not exclusively solidify, the sticky hand in surface, with the variable color of cotton balls libation at an ancient wedding ceremony solvent wiping cotton balls, and hangs with resinous substances: construction environment temperature is with 15-25 degrees Celsius.
Advantage of the present utility model:
The fiber reinforced structure of the damaged cement pole tempering of power transmission and transformation described in the utility model, easy and simple to handle, have extremely strong caking property and water resistance, paint film is firm, does not peel, and does not burst, ageing-resistant, acid-alkali-corrosive-resisting, and application life reaches 20-30.
