High-intensity and light-weight pole tower

Abstract

The invention relates to the technical field of a transmission pole tower, in particular to a high-intensity and light-weight pole tower. The high-intensity and light-weight pole tower comprises a center shaft, the center shaft is spliced by several modules from top to bottom, each module comprises three layers of structures, and the structures are all combinations which are combined by several splicing blocks in the circumferential direction. The whole pole tower is modularized so that the pole tower can be transported in a decomposing mode, and the transport difficulty is lowered; meanwhile,through splicing of multiple layers of structures and each layer of structure, the intensity of the pole tower is effectively increased, and the design of different hierarchical structures and splicing seams in all layers of structures both support and reinforce the pole tower.

Description

technical field [0001] The invention relates to the technical field of power transmission poles and towers, in particular to a high-strength and light-weight poles and towers. 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. Erection in corridors; if cable lines are laid on the same path, the investment is very large, and the 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...

Problems solved by technology

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. Erection in corridors; if cable lines are laid on the same path, the investment is very large, and the 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; commonly used concrete and steel are also used to form Electric poles and towers, however, the weight of these materials makes transportation and installation costs prohibitive. In addition, steel is highly conductive, while concrete structures expand and contract with temperature, causing longitudinal cracks. This problem has not been well solved.

[0003] At present, traditional transmission poles and towers generally have defects such as heavy weight, perishability, corrosion or cracking, poor durability, and short service life, and there are also certain difficulties in construction and transportation operations.
