据微信公众号"国家铁路局"消息，11月14日，国家铁路局发布通报称，针对近日媒体关注的银巴铁路桥梁用橡胶材料"以次充好"问题，兰州铁路监管局高度 重视，立即成立调查组，赶赴现场开展调查核实。 日前，新华社旗下《经济参考报》调查发现，中国铁建旗下中铁十六局在施工过程中，使用的一种桥梁用橡胶材料疑似存在质量问题。记者现场随机抽取的 多处已铺设三元乙丙橡胶板能轻易被割开、扯断。送检结果显示其拉伸强度仅为1.78MPa，仅为标准（"≥12MPa"）的15%，主要成分为性能较差的异戊二烯 橡胶，而非合同要求的三元乙丙橡胶，且部分产品无厂家标识，涉嫌以次充好。 据了解，三元乙丙橡胶板铺设在铁路桥两侧钢横梁上，能避免混凝土电缆槽和钢横梁两个刚性结构之间的直接接触，使受力均匀，起到缓冲、防水和延长桥 体使用寿命的作用。 | 序号 | 项目 | | 单位 技术要求 试验方法 | | | --- | --- | --- | --- | --- | | 1 | 邵A硬度 | 度 | રેરેન્દ | GB/T 531.1 | | 2 | 拉伸强度 | MPa | ≥12 | GB/T528 | | 3 | 拉断伸长率 | 0/0 ...
