Description

Technical Field

[0001] The present invention relates to the technical field of cement utility poles, and in particular to a cement utility pole that is easy to assemble and erect and a manufacturing method thereof. Background Art

[0002] In the construction of power transmission and communication lines, cement utility poles serve as crucial infrastructure supporting conductors and related equipment, and are widely used in urban and rural power grids and communication networks. Traditional cement utility poles typically utilize a monolithic structure, characterized by mature manufacturing processes, high mechanical strength, and excellent stability and durability in practical applications. However, with the development of urban construction and limited transportation conditions, traditional cement utility poles have exposed numerous problems during transportation and construction.

[0003] First, because traditional cement utility poles are relatively long, generally between 8 and 18 meters, or even longer, their transportation places high demands on road width, turning radius, and bridge load-bearing capacity. This is especially true in mountainous and hilly areas with complex terrain or inconvenient transportation. Transportation is difficult and costly, and even temporary transportation channels need to be built, further increasing project investment.

[0004] Secondly, the hoisting and erection of traditional cement poles on the construction site is a cumbersome process requiring large lifting equipment. This is not only limited by the on-site working environment but also poses certain safety risks. Furthermore, once formed, monolithic cement poles are difficult to adjust flexibly. If the required terrain or height changes are encountered, the poles often need to be re-customized to different specifications, resulting in wasted resources and construction delays.
