摘要
为克服桥面防水层的完整性对混凝土耐久性的影响,在分析现场施工损伤的基础上,研究了采用抗施工机械损伤、抗热集料刺破及不透水性等评价桥面防水层的抗施工损伤特性,提出了相应的试验方法,对常见防水材料的抗施工损伤性能进行对比和评价,确定出防水层的最小设计、施工厚度.结果表明,抗损伤能力与防水层厚度有密切的关系,涂膜层厚度应不小于1.5mm,卷材类则不应小于2.5mm,并且卷材类的抗透水性能明显优于涂膜类.
To get rid of the integrity of waterproofing layer on the bridge floor affecting the concrete durability, and based on analyzing the field construction trauma, the paper has adopted anti-construction machine hurt, anti-heat aggregate breakthrough and waterproofing function to evaluate the anti-construction hurt performance of the waterproofing layer on the bridge floor and presented relative experimental methods. Besides, the paper has evaluated and compared the anti-construction hurt function of common waterproofing materials, and further determined the minimum design and construction thickness of waterproofing layer. The results show that there is close relationship between anti-hurt function and waterproofing layer thickness, and the thickness of film shouldn't be less than 1.5 mm and that of coiled material shouldn't be less than 2.5 mm, and the waterproofing ability of coiled materials is obviously better than that of films.
