加强钢筋混凝土保护层厚度的控制措施

摘要

论述了混凝土保护层的作用，从钢筋、模板、混凝土浇筑、垫块四方面分析了钢筋混凝土保护层厚度偏差的原因，并对桥梁及隧道的混凝土保护层厚度的控制措施进行了详细说明，使设计满足相关规范要求。%The paper discusses the role of concrete protecting layer, analyzes steel reinforced concrete protecting layer thickness deviation causes from four aspects of steel, template, concrete grouting and masonry, and specifically illustrates control measures of bridge and tunnel concrete protecting layer, so as to make the design meet relevant demands.
