Abstract
Reinforced concrete antirust wire pole belongs to the aseptic technic of reinforced concrete product, the present invention provides a kind of inhibiter with antiseptic property that mixes for the corrosion that solves at coastal saline and alkaline area reinforced concrete pole in cement, and at the electric pole root by burying the method for locating radially to add the metal blind plate on the face of land underground along electric pole.The present invention can be used for various electric poles and also can be used for the anticorrosion of skeleton construction in the civil engineering, has prolonged work-ing life greatly.
Description
The present invention is the anti-corrosion method that belongs to a kind of reinforced concrete product.
The Steel Concrete electric pole that sets up in the marshy terrain of saline and alkaline area and coastland, be subjected to corrosion such as acid, alkali, salt, destruction is very serious, bring certain difficulty to power supply, cause serious accident sometimes, make economy be subjected to massive losses, adopt at present anticorrosive measure to be mostly: electric pole exposed apart from ground about one meter highly brush pitch or Resins, epoxy, though this method short-term has certain effect against corrosion, but because there are following three problems in this method: be interrupted moist district about one meter, fail to eradicate the capillarity of soil; The protective layer of brushing easily comes off; The corrosion of Framework Of Steel Reinforcement does not solve in the electric pole, therefore fails from solving anticorrosion problem in fact.Vacuum infusion techniques is because complicated difficult use of apparatus and process in addition.
The object of the present invention is to provide a kind of simple reinforced concrete pole of antiseptic property technology that has, this electric pole is specially adapted to coastland and saline and alkaline marshy terrain.
The invention is characterized in when making reinforced concrete pole, in cement, mixed a kind of inhibiter, because the existence of this inhibiter makes electric pole self have stronger antiseptic property with antiseptic property.
The prescription of inhibiter of the present invention is as follows:
Water reducer (NNO): (methyne sodium dinaphthalenesulfonate), its content are 0.5～0.9% of cement weight.
M-promotor, (thioresorcin a pair of horses going side by side thiazole), its content is 0.01～0.04% of cement weight;
Sodium phosphate, content are 0.01～0.04% of cement weight;
Sodium Nitrite, (N
aNO
2) content is cement weight 0.5～3%;
Trolamine, content are cement weight 0.01～0.04%.
It is very simple that this prescription uses, it earlier water-soluble again with cement mixing, or directly with cement mixing add again the water stirring all can, adopt general silicate cement.After prescription adds in the cement, do not influence the technological process that electric pole is made at all.
Another feature of the present invention is to locate on the face of land radially to add the metal blind plate along electric pole near burying underground at the electric pole root, its objective is restriction because wicking action water and saline alkali corrosion continue upwards to stretch.It also can be two plates up and down that blind dividing plate can be one, is about to electric pole segmentation manufacturing, then two blocks of blind plates is connected with welding or with bolting.
Fig. 1 adds the synoptic diagram of blind dividing plate for reinforced concrete antirust wire pole.1 is the body of rod among the figure, and 2 is the blind dividing plate of flange-type, and 3 is bolt, and 4 is ground surface.
Embodiment: source mill of Bei Jingliang township Electric Power Transmission ﹠ transformation Company makes isometrical φ 300 electric poles;
Adopt 400
#Silicate cement adds water reducer 0.89%(cement weight), M-promotor 0.02%(cement weight); Sodium Nitrite 2%(cement weight); Sodium phosphate: 0.03%; Trolamine: 0.02%.The Steel Concrete azoiling that does not add blind dividing plate that uses above-mentioned prescription to make has used does not see corrosion phenomenon yet more than 3 years.
Reinforced concrete antirust wire pole of the present invention has tangible corrosion-resistant than the ordinary reinforced concrete electric pole; For example at forest land in ancient times, Tianjin band, the common bar of burying underground, six months just find that serious cracking phenomena is arranged, and treeatedpole has been buried several years underground, intact substantially, any corrodibility vestige has been can not see on the surface.In addition, do not change the technological process of original system bar when making treeatedpole, compare, have features such as laborsaving, economical with spread coating.
The present invention can be used for common telecom pole, high pressure and normal pressure send various electric poles such as ordinary reinforced concrete electric pole that electricity uses and prestressed electric wire pole, equal-diameter pole, the present invention also is applicable to that the skeleton construction in the geographic civil engineering of high corrosion is anticorrosion simultaneously, has prolonged work-ing life greatly.
Claims (4)
