水工结构物混凝土保护层的作用及质量控制

Role and quality control of concrete cover of hydraulic structures

针对水工结构物目前混凝土保护层厚度普遍控制不严的现状,简要分析了混凝土保护层厚度对钢筋混凝土结构的承载能力与耐久性的影响,同时结合大量的检测实践,指出当前水工结构施工在混凝土保护层厚度控制方面存在的不足,并对这方面的质量控制提出具体建议,以期进一步引起对混凝土保护层施工质量的重视。

Aiming at the current situation that the control of concrete cover thickness of hydraulic structure is generally not strict,this paper analyzes the impact of concrete cover thickness on the bearing capacity and durability of hydraulic reinforced concrete entities.Meanwhile,through a large number of detection practices,we find out the weaknesses in the control of concrete cover thickness during construction of the hydraulic structure,and propose suggestions on it.
