Problems solved by technology

A few years later, affected by factors such as air, rainy and snowy weather, inorganic salts in the soil, and the quality of the hot-dip galvanizing treatment at that time, different degrees of corrosion will inevitably occur. The corrosion of the rods is mainly concentrated from 30 cm above the ground to 50 cm below the ground. The parts buried in the ground and exposed to the air are not seriously corroded. When the rod is slightly corroded, only a layer of floating rust is formed on the surface. When it is heavy, the diameter of the rod is reduced to form a neck-shaped rust. The ring belt, in severe cases, leads to complete rusting of the tie rods. The corrosion defect of the tie rods directly affects the safe operation of the line, and after a large number of tie rods are replaced, they still face the same working environment as the original tie rods. After several years of operation, they will still rust

Embodiment Construction

[0028] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0029] Such as figure 1 As shown, a method and mold for improving the corrosion resistance performance of the pull rod, the method steps are,

[0030] 1. Mold selection

[0031] Such as figure 1 , 2 As shown, the selection length is 50-80cm, the diameter is 75cm, and the cylindrical PVC casing 2 cut longitudinally is provided with a cover 3 at the bottom and top of the casing 2, and a through hole 4 is provided at the center of the cover 3, and the through hole The diameter is the same as that of the pull rod 1;

[0032] 2. Implementation process

[0033] (1) First dig out the soil and check the corrosion layer of the pull rod. If the pull rod is seriously corroded, the pull rod must be replaced;

[0034] (2) Slightly corroded pull rods. C...

Abstract

The invention discloses a method and a die for improving the corrosion resistant performance of a pull rod and relates to the technical field of power supply equipment. The method is characterized by comprising the following steps of: firstly, digging up soil and checking a corrosion layer of the pull rod; if the pull rod is seriously corroded, requiring to replace the pull rod and carrying out corrosion resistant treatment on the corroded part on the pull rod; secondly, mounting the die on the pull rod; fixing the pull rod at the center of the die by using an iron bolt; pouring concrete in the die; after pouring, covering the top of the die with a cover, extracting the iron bolt and backfilling soil; and dismantling the die after one to two days and continuously recycling the die. According to the method and the die disclosed by the invention, from a view of enhancing the corrosion resistance of the pull rod, the corrosion resistance of the pull rod can be effectively improved, thereby the aim of prolonging the service life of the pull rod is achieved and the maintenance cost of replacing the pull rod is reduced.

Description

technical field [0001] The invention relates to the technical field of power supply equipment, in particular to a method and a mold for improving the anti-corrosion performance of a pull rod. Background technique [0002] In my country, with the continuous deepening of the transformation of urban power grids and rural power grids, the problem of natural damage to power facilities has become increasingly serious. Most of the pull rods currently on the market are hot-dip galvanized on the surface. A few years later, affected by factors such as air, rainy and snowy weather, inorganic salts in the soil, and the quality of the hot-dip galvanizing treatment at that time, different degrees of corrosion will inevitably occur. The corrosion of the rods is mainly concentrated from 30 cm above the ground to 50 cm below the ground. The parts buried in the ground and exposed to the air are not seriously corroded. When the rod is slightly corroded, only a layer of floating rust is formed...
