Method for reinforcing transmission line iron tower

Abstract

The invention provides a method for reinforcing a transmission line iron tower. The method comprises the following steps of: selecting a panel length of the transmission line iron tower, and measuring the net distance between two opposite ends of a gusset plate at two adjacent panel points of the same reinforced principal material according to the selected panel length; intercepting the length ofthe reinforced principal material according to the net distance; punching bolt holes on two limbs of the selected reinforced principal material and two limbs of a reinforcing principal material respectively, and aligning the bolt holes on the reinforcing principal material with the corresponding bolt holes on the reinforced principal material mutually; splicing the two limbs of the reinforcing principal material on the reinforced principal material, and fixing by utilizing fastening bolts; reinforcing the other three reinforced principal materials of the panel length; after the four reinforced principal materials of the panel length are reinforced, reinforcing the reinforced principal materials of other panel lengths in a reinforcing mode which is the same as that of the reinforced principal materials of the panel length; and reinforcing the panel points by utilizing angle steel.

Description

Technical field: [0001] The invention relates to a method for strengthening a power transmission line iron tower, in particular to a method for strengthening the main material of a power transmission line iron tower. Background technique: [0002] With the rapid development of my country's economy and society, the demand for electric power is becoming stronger and stronger, the dependence of modern society on electric energy is increasing, and the requirements for the safety and reliability of power grids are also getting higher and higher. The transmission tower is an important support of the power grid. In the natural environment, it is often attacked by severe weather disasters, causing the structure of the tower to be irreversibly damaged and even collapsed. [0003] By reinforcing the main material of the transmission line tower, the ability of the transmission line to resist disaster weather can be improved, and the safe operation level of the transmission line can be ...

AI Technical Summary

Problems solved by technology

There are many inconveniences in the practical application of the above-mentioned

First of all, the above-mentioned main material reinforcement method has high requirements for joint processing, which increases the project cost

Secondly, due to the complex force at the joint, and the use of single-leg splicing or back-to-back installation of two connecting angle steels, the eccentricity of the main material is relatively large when the force is applied, and the reinforcement effect is not significant

Thirdly, single-leg splicing is used. In order to reduce the eccentric force, double-angle steel is generally used, which will increase the total weight of the reinforcement material, thereby increasing the load weight of the transmission line tower and resulting in poor economy.

Similarly, installing two connecting angles back to back will also increase the total weight of reinforcement materials, thereby increasing the load weight of the transmission line tower and resulting in poor economics
