Abstract
The invention provides a reinforcement method for reinforcing a concrete pole by a basalt fiber reinforced polymer sheet. The reinforcement method comprises the following steps: 1) carrying out scabbling processing on a damaged concrete pole, polishing to remove the carbonized surface layer of the concrete pole, and scraping the damaged, chapped, falling and rimous concrete layer of the concrete pole; 2) polishing and descaling exposed and corroded reinforcing steel bars and iron hoops, painting anti-corrosion epoxy resin after descaling is carried out, and shielding and tamping crack positions by crack repair adhesive; 3) painting resin adhesive, longitudinally pasting one layer of basalt fiber reinforced polymer sheet along the concrete pole to surround the whole concrete pole, and then, pasting a basalt fiber reinforced polymer sheet hoop; and 4) after the adhesive is completely stable, painting one layer of epoxy resin on the surface of the basalt fiber reinforced polymer sheet to cause coarse sands to be stuck on the surface of the basalt fiber reinforced polymer sheet, and painting protective paint. The concrete pole has the advantages of ageing resistance, high temperature resistance, acid and alkali resistance, favorable fire resistance and insulating property, strong binding force between the basalt fiber reinforced polymer sheet and the concrete pole, environment protection, no pollution and high strength.
Description
Technical field
The present invention relates to the reinforcement means of the reinforced cementitious electric pole of a kind of basalt fiber cloth.
Background technology
Concrete wire pole is divided into prestressing force concrete wire pole and non-prestressed concrete wire pole, this kind concrete wire pole structure is simple, construction costs is low, DL/T741-2001 " aerial power transmission line operating standard " regulation is widely adopted: crackle appears in prestressing force concrete wire pole in the straight line pole of 110-220kW aerial power transmission line, there is vertical, horizontal crackle in non-prestressed concrete wire pole, width should process more than during 0.2mm.Existing many power transmission sequences enter the aged phase at present, and concrete wire pole seminess is serious, are badly in need of repairing.
Summary of the invention
Technical problem to be solved by this invention is the reinforcement means providing the reinforced cementitious electric pole of a kind of basalt fiber cloth, anti-aging, high temperature resistant, acid and alkali-resistance, fire resistance and insulating properties are good, the adhesion of basalt fiber cloth and cement electric pole and resin is strong, and environment friendly and pollution-free, intensity is high.
For solving above-mentioned existing technical problem, the present invention adopts following scheme: with the reinforcement means of the reinforced cementitious electric pole of basalt fiber cloth, comprise the following steps:
The first step, first dabbing process is carried out to impaired cement electric pole, go to the top layer of cement electric pole carbonization until expose new cement layer with sander polishing, pick and beat that cement electric pole impairedly to be chapped, come off, the cement layer that chaps is until solid position;
Second step, to exposing the reinforcing bar of corrosion, iron hoop carries out polishing rust cleaning, brushing resistance rust epoxy resin after rust cleaning, and the position epoxy mortar of cement electric pole defect is filled up levelling, and location of cracks crack repairing glue shields and tamps;
3rd step, brushing resin glue, longitudinally paste one deck basalt fiber cloth by whole cement electric pole ring bag along cement electric pole, more sticky note basalt fiber cloth hoop;
4th step, after bonding adhesive complete stability, at basalt fiber cloth external coating one deck epoxy resin, rough sand is bonded at basalt fiber cloth surface, at cement electric pole outside coating one deck protective paint after sticky note.
Beneficial effect:
The reinforcement means with the reinforced cementitious electric pole of basalt fiber cloth that the present invention adopts technique scheme to provide, anti-aging, high temperature resistant, acid and alkali-resistance, fire resistance strong with the adhesion of concrete and resin and insulating properties are good, basalt fiber cloth takes from natural crystal and without any additive, environment friendly and pollution-free, intensity is high.
Detailed description of the invention
With the reinforcement means of the reinforced cementitious electric pole of basalt fiber cloth, comprise the following steps: the first step, first dabbing process is carried out to impaired cement electric pole, go to the top layer of cement electric pole carbonization until expose new cement layer with sander polishing, pick and beat that cement electric pole impairedly to be chapped, come off, the cement layer that chaps is until solid position; Second step, to exposing the reinforcing bar of corrosion, iron hoop carries out polishing rust cleaning, brushing resistance rust epoxy resin after rust cleaning, and the position epoxy mortar of cement electric pole defect is filled up levelling, and location of cracks crack repairing glue shields and tamps; 3rd step, brushing resin glue, longitudinally paste one deck basalt fiber cloth by whole cement electric pole ring bag along cement electric pole, the more sticky note wide 200mm basalt fiber cloth hoop of annular, adjacent hoop spacing 500mm; 4th step, after bonding adhesive complete stability, at basalt fiber cloth external coating one deck epoxy resin, rough sand is bonded at basalt fiber cloth surface, at cement electric pole outside coating one deck protective paint after sticky note.
The modulus of elasticity (Gpa) of basalt fiber cloth is 91-110, and filament diameter reaches (μm) 7-15, density (g/cm3) 2.63-2.65, and hot strength (Mpa) is 3000-4800, low price.After the reinforced cementitious electric pole of basalt fiber cloth, anti-aging, high temperature resistant, acid and alkali-resistance, fire resistance strong with the adhesion of concrete and resin and insulating properties are good, and basalt fiber cloth takes from natural crystal and without any additive, environment friendly and pollution-free, intensity is high.
