Detailed description of the invention
As depicted in figs. 1 and 2, for overlength can not cement electric pole made in one piece, use segmentation manufacture,
The present embodiment uses two sections of manufactures, the first bar segment 1 and the second bar segment 2, two bar segment will be divided into by cement electric pole
Manufacture respectively.The top of the first bar segment 1 is provided with the first bar segment steel plate ring 3；In the second bar segment 2
Bottom is provided with the second bar segment steel plate ring 4, and the external diameter of the two steel plate ring is identical, and less than two bar segment
External diameter.
First bar segment steel plate ring 3 and the welding of the second bar segment steel plate ring 4 form all-in-one-piece Interal fixation circle,
Interal fixation circle surface-coated has preservative treatment layer 6.It is externally provided with outer protective structure, outward at preservative treatment layer 6
Layer safeguard structure includes the putty layer 7 arranged outside preservative treatment layer, and described putty layer 7 is externally provided with carbon fiber and strengthens
Layer 8.Wherein, described putty layer 7 uses epoxy anticorrosion putty or Vinylidene Chloride anticorrosive putty.Described carbon fiber
Enhancement Layer 8 uses epoxy glue or polyvinyl gluing and be fixed on the surface of putty layer 7.
After first bar segment 1 and the second bar segment 2 are transported to erection scene, by the first bar segment steel plate ring 3 and second
Bar segment steel plate ring 4 docks and guarantees coaxial, is welded on by two steel plate rings with electric welding or gas welding the most at the scene
Together.After welding, carry out derusting anti-corrosive process, form preservative treatment layer 6.In the conventional technology, often
Carrying out field polish rust cleaning with sand paper or emery wheel, job site dust pollution is serious.Therefore, the present invention uses
Derusting anti-corrosive one-step method Non-water washing processes technique, and job site, will not be to environment without dust.Tool
The surface treatment liquid of body employing formula as below:
Phosphoric acid (65%): 200～350ml/L
Zinc oxide: 15～30g/L
Polyhydroxy acid: 2～30g/L
Sodium molybdate: 2～20g/L
Surfactant: 0.2～5g/L
Wherein, it is preferred to use the surface treatment liquid of formula as below:
Phosphoric acid (65%): 250ml/L
Zinc oxide: 20g/L
Polyhydroxy acid: 15g/L
Sodium molybdate: 10g/L
Surfactant: 2g/L
Polyhydroxy acid includes citric acid, tartaric acid, gluconic acid etc., conventional citric acid；Surfactant is
Conventional nonionic surfactant, such as OP-10, TX-10, triton x-100 etc..
It is very simple that derusting anti-corrosive one-step method Non-water washing processes technique, only need to be on steel plate ring surface brushes one layer
State surface treatment liquid, after it dries naturally, the rusty scale on steel plate ring surface can be converted into preservative treatment layer 6,
This preservative treatment layer 6 has good corrosion resistance, it is possible to follow-up putty layer has good adhesion.
After preservative treatment layer 6 parches completely, last layer putty can be scraped on its surface, form putty layer 7.
The effect of Puttying layer, in addition to the soldered 5 between by two steel plate rings is filled and led up, also has waterproof action,
Prevent outside rain penetration from entering, and then corrosion steel plate ring.After putty layer 7 solidification, with sand papering to greasy
Sublayer 7 outer surface flushes the construction that can carry out next step with the outer surface of cement electric pole.
In order to prevent the cement air slaking near steel plate ring, stop the infiltration of rainwater and cement electric pole joint is entered
Row reinforcement processes, and the present invention uses the processing method that carbon fiber winding strengthens.Due to carbon fiber have intensity and
Modulus is high, and density is low, higher than performance, and without creep, fatigue durability is good, and thermal coefficient of expansion is little, corrosion resistance
The good advantage waited, will be wrapped in the outside of putty layer 7 layer by layer after its impregnation, formed after it solidifies firm and
The carbon fiber enhancement Layer 8 that intensity is good.
The intensity of carbon fiber enhancement Layer 8 and the proportional relation of its thickness, therefore the thickness of carbon fiber winding should not
Less than 5mm.And carbon fiber enhancement Layer 8 two ends should exceed the two ends of putty layer 7, stretch out at least 1cm,
The most just there is enough stiffening effects.Epoxy glue commonly used by glue for carbon fiber winding or polyvinyl glue is
Can, glue used can be modulated the most before use, according to construction requirement, permissible by adjusting formula
Change hardening time, beneficially site operation.
One section of electric pole wherein, the first bar segment 1 or the second bar segment 2 are provided with Thread holder.Such as Fig. 3 institute
