防腐蚀混凝土电杆的设计以及性能研究

Design and Performance Study of Anticorrosive Concrete Poles

沿海地区和盐碱地区的混凝土电杆易受高盐环境腐蚀,导致混凝土结构碳化、钢筋腐蚀,影响电杆的耐久性。为了提高电杆的防腐性能,电杆材料采用高强度混凝土以及抗硫酸盐防腐剂,并对电杆基础和杆身进行防腐涂层覆盖以及PE板/膜锚固,该防腐工艺结合了化学防腐和物理隔绝法的优点,创造性地将混凝土电杆从地基处理至顶部防腐作为一个整体进行设计,将化学防腐方法和物理防腐方法有机结合起来,提高了电杆的防腐性能,减轻了混凝土电杆重量,增强了混凝土电杆的稳固性。

Concrete poles in coastal and saline alkali areas are prone to corrosion in high salt environments,leading to carbonization of concrete structures and corrosion of steel bars,which affects the durability of poles.In order to improve the anti-corrosion performance of the poles,high-strength concrete and sulfate resistant anti-corrosion agents are used as the pole material.The pole foundation and body are covered with anti-corrosion coatings and anchored with PE plates/films.This process combines the advantages of chemical anti-corrosion and physical isolation methods,creatively designing the concrete pole from foundation treatment to top anti-corrosion as a whole,organically combining chemical anti-corrosion and physical anti-corrosion methods,improves the anti-corrosion performance of the poles,reduced the weight of concrete poles,and enhances the stability of the concrete poles.
