Abstract
The invention discloses a power transmission line concrete rod weld joint corrosion prevention method. According to the method, a protection device with the inner diameter equal to the outer diameter of a concrete rod and being provided with upper and lower seal rings is adopted to isolate the corrosive damage from corrosive gases of all kinds outside, ultraviolet as well as frost and rain water to the weld joints and the metal at the heat affected zone of the weld joints of the power transmission line concrete rod so as to improve the corrosion resistance of the concrete rod. The method has an obvious effect of preventing the corrosions at the weld joints and the metal at the heat affected zones of the weld joints of the power transmission line concrete rod, and can effectively prevent power failure in large area caused by collapse of the power transmission line concrete rod due to the cracking of the concrete rod caused by corrosion of the weld joints. Therefore, the method can improve the production safety level of power transmission and distribution. The method is applicable for protection for weld joints of power transmission line concrete rods and concrete frames of transform substations.
Description
Technical field
The present invention relates to a kind of electric transmission line concrete pole weld seam and the guard method of weld heat-affected zone anti-corrosion of metal, belong to ultra-high-tension power transmission line operation maintenance maintenance equipment technology field.
Background technology
The concrete bar is requisite important component in transmission and distribution network, the transformer station, anticorrosion at ultra-high-tension power transmission line operation maintenance maintenance equipment technology field concrete bar weld seam is the important leverage of electric line safety in production, and its safe operation is directly connected to the safety and stability of electrical network and to the reliability of customer power supply.
And the exposed corrosion that is subject to various corrosive gas in the atmosphere, ultraviolet ray and frost rainwater of general concrete bar weld seam.Use the present invention will effectively prevent the weld corrosion of concrete bar, thereby avoid serious because of the weld corrosion of concrete bar, mechanical strength descends, weld cracking, and make electric transmission line concrete pole fall bar, and cause the generation of large area blackout, effectively ensure the transmission and distribution network safety in production.
Summary of the invention
The objective of the invention is, in order to promote the antiseptic property of concrete bar weld seam, ensure the safety of electric transmission line concrete pole, the present invention discloses a kind of electric transmission line concrete pole weld seam anti-corrosion protection method.
Technical scheme of the present invention is; utilize internal diameter the protective device with upper-lower seal circle identical with concrete bar external diameter; in order to isolate extraneous various corrosive gas, ultraviolet ray and frost rainwater electric transmission line concrete pole weld seam and weld heat-affected zone corrosion of metal are destroyed; promote the Corrosion Protection of concrete bar, thereby reach the long-lived purpose of concrete bar.
The described protective device of the inventive method; consisted of by two symmetrical semicircle cylinder protective covers; be that the sealing ring of square type embeds protective cover up and down in the inner surface recesses of two ends with the cross section; evenly tighten the fastening snap close of protective cover; protective device is tightly wrapped up concrete bar weld seam; effectively isolate extraneous various corrosive gas, ultraviolet ray and frost rainwater electric transmission line concrete pole weld seam and weld heat-affected zone corrosion of metal have been destroyed, promoted concrete bar weld seam and weld heat-affected zone anticorrosive metal performance.
The invention has the beneficial effects as follows, do not adopt the exposed weld seam of concrete bar of concrete bar weld seam anti-corrosion protection method to compare with other, the concrete bar weld seam anti-corrosion protection cover that concrete bar weld seam anti-corrosion protection method of the present invention forms has following characteristics: 1. to concrete bar weld seam omnibearing protection, reduce ultraviolet ray and frost rainwater to the erosion of concrete bar weld seam; 2. reduce in the atmosphere various corrosive gas to concrete bar weld seam and weld heat-affected zone corrosion of metal; 3. mounting method is simple, rapid.This method is simple and easy to do, protective device is installed rapidly.The present invention is obvious to the anticorrosion ability of electric transmission line concrete pole weld seam and weld heat-affected zone metal.Can effectively prevent concrete bar weld corrosion cracking and cause electric transmission line concrete pole to fall bar, the large area blackout of initiation improves electrical network power transmission and distribution safety in production level.Simultaneously, reduce the negative effect that large-area power-cuts produces all sectors of society.On the other hand, the protective device that the present invention forms is simple in structure, selects materials easy and durable, and reliability is also very high.
The applicable protection to electric transmission line concrete pole and transformer station's concrete framework weld seam of the present invention.

The specific embodiment
The specific embodiment of the present invention as shown in Figure 1 and Figure 2.
The embodiment of the invention adopts concrete bar weld joint protective device that the electric transmission line concrete pole weld seam is protected.Concrete bar weld joint protective device is made of two symmetrical semicircle cylinder protective covers 1, semicircle cylinder protective cover 1 is processed by cast aluminium, the interior radius of circle of semicircle cylinder protective cover is identical with concrete bar external diameter, and two ends are along being processed with the groove vertical with semicircle cylinder on the inner arc surface about semicircle cylinder protective cover 1 inner cylinder face; Be that the sealing ring 2 of square type embeds protective covers up and down in the inner surface recesses of two ends with the cross section; evenly tighten the fastening snap close of protective cover; protective device is tightly wrapped up concrete bar weld seam; effectively isolate extraneous various corrosive gas, ultraviolet ray and frost rainwater electric transmission line concrete pole weld seam and weld heat-affected zone corrosion of metal have been destroyed, promoted concrete bar weld seam and weld heat-affected zone anticorrosive metal performance.The first butt welded seam external coating rustproof paint of palpus before concrete bar weld joint protective device is installed after antirust the doing, is installed concrete bar weld joint protective device, has avoided the oxide etch of a small amount of air butt welded seam of retention, can protect better weld seam to avoid corrosion.
