A high-strength steel transmission tower with a honeycomb structure

Abstract

The invention provides a high-strength steel transmission pole tower with a honeycomb structure, which includes a tower body vertically arranged on the foundation, and a horizontal arm on the tower body. The improvement is that the tower body includes a main pipe and a honeycomb arranged in the main pipe Structure, the honeycomb structure is composed of six hollow regular hexagons surrounding a hollow regular hexagon. The high-strength steel transmission tower with a honeycomb structure provided by the present invention improves the overall bearing capacity and local stability of the transmission tower, and prevents spalling during processing and reduces welding by reducing the thickness of the high-strength steel plate used in the steel pipe tower. Difficulty, to a certain extent, solves the difficulty of using high-strength steel in power transmission towers, and promotes the application of high-strength steel in power transmission towers.

Description

technical field [0001] The invention relates to a transmission tower, in particular to a high-strength steel transmission tower with a honeycomb structure. Background technique [0002] In recent years, with the increasing shortage of urban land and the rapid increase of electricity load, the power supply network can no longer meet the needs of the development of electricity load. For this reason, urban planning departments generally provide narrow high-voltage line corridors or use green belts as passages for high-voltage overhead lines. Ordinary self-supporting iron towers require relatively large corridors because their roots are wide, occupying a lot of space, and are not suitable for restricted areas. Corridor erection; if the cable line is laid on the same path, the investment is very large, and the engineering construction unit is often difficult to accept, and it is easily affected by urban construction, and it is not easy to overhaul in the event of a line accident;...

AI Technical Summary

Problems solved by technology

[0006] First, the thickness of high-strength steel pipes is limited, and local buckling problems are prone to occur, resulting in local instability of the tower;

[0007] Second, if a thicker high-strength steel pipe is processed, lamellar tearing is prone to occur during processing;

[0008] Third, the welding of thicker high-strength steel pipes is more difficult, and the welding quality cannot be guaranteed
