现以已建成的牡丹江磨刀石互通AK0+679匝道桥为依托,结合工程实际,在承台、墩柱、盖梁、箱梁等混凝土结构施工过程中采取一系列的保护层控制措施,通过检测验证,相关结构物保护层厚度得到了很好控制,确保了混凝土结构中受力钢筋的有效锚固和构件的耐久性,达到了提高了混凝土结构质量的目的,并为今后混凝土保护层厚度控制提出参考和建议。
Based on the completed AK0 + 679 Ramp Bridge of Mudanjiang Grindstone Interchange and the actual engineering practice, a series of protective layer control measures are adopted during the construction of concrete structures such as caps, pier columns, capping beams and box girders, Testing and verification, the thickness of the protective structure of the relevant structure has been well controlled to ensure the effective anchoring of reinforced concrete structure and the durability of components to achieve the purpose of improving the quality of concrete structures, and for the future control of concrete cover thickness Make reference and suggestion.
