Three-column steel pipe tower

Abstract

The invention relates to a three-column steel pipe tower applied to a power transmission line. The three-column steel pipe tower comprises three main pipes which are vertically arranged and distributed in a shape of a triangle, and a plurality of layers of horizontal triangular spacers formed by three horizontal pipes and used for connecting the three main pipes. Two main pipes are arranged on the pressure side of the three-column steel pipe tower, and the rest one is arranged on the tension side of the three-column steel pipe tower. The pipe diameter of the main pipe arranged on the tension side of the three-column steel pipe tower is greater than the pipe diameters of the main pipes arranged on the pressure side of the three-column steel pipe tower. The three-column steel pipe tower is simple in structure, elegant in appearance, small in occupied area and specific in power transmission, and is suitable for power transmission engineering in city districts. Compared with a traditional single-pipe tower, the three-column steel pipe tower is larger in overall rigidity, can effectively reduce the displacement of a tower top, and can also lower the construction capacity of an iron tower and the foundation, so as to obtain the purpose of saving resources. The main pipes of the three-column steel pipe tower are more reasonable in pressure bearing, and better in the stability of triangular space.

Description

technical field [0001] The invention relates to a power transmission tower used in power transmission and transformation line engineering, in particular to a steel pipe tower with a three-column structure. Background technique [0002] The transmission tower is a towering structure with a large number of projects and is very important. As the power facility of an important lifeline project, various types and purposes of transmission towers are often used in power transmission and transformation line projects. [0003] With the continuous improvement of transmission capacity and voltage level of transmission lines, double-circuit and multi-circuit lines on the same tower have become an inevitable trend in economically developed areas. In economically developed areas, the requirements for line corridors are becoming more and more stringent, the site is getting smaller and smaller, and the line corridors are getting narrower and narrower. The force of a single pole may not be a...

AI Technical Summary

Problems solved by technology

For multi-circuit corner towers with particularly large loads, single-rod or double-rod steel pipe towers are used. Due to the large bending moment at the root of the rods, the diameter of the main pipe is large, the utilization rate of materials is low, and even processing difficulties occur. Therefore, the development A new type of tower structure suitable for multi-circuit transmission lines in urban areas is very necessary
