Description

Technical Field

[0001] This invention relates to the field of utility pole technology, and more specifically to a high-bending-moment concrete utility pole. Background Technology

[0002] Currently, traditional cement poles are prone to cracking and insufficient load-bearing capacity in extreme climates and long-span scenarios. The bending moment bearing capacity of ordinary poles is: cracking moment greater than or equal to 58.5 kN·m, and load-bearing capacity test moment greater than or equal to 117.0 kN·m, which cannot meet the requirements of new scenarios such as 5G base stations and ultra-high voltage power transmission. Furthermore, the existing steel reinforcement configuration results in heavy weight and high cost; and the concrete formula leads to insufficient durability.

[0003] Therefore, it is necessary to develop a high-bending-moment concrete pole to solve the above problems. Utility Model Content
