隧道防火涂料施工工艺研究

   

YINYAN

        隧道是整个公路交通运输中比较薄弱的环节,隧道防火涂料其安全与否直接影响着整条道路的畅通。隧道中发生交通事故或者出现地质灾害对道路通行影响时间长,恢复通行难度大;而在发生交通事故的各种情况尤其以交通火灾事故影响最为严重。为了减少交通事故造成的损失,隧道在建设和养护期采取防火措施。其中包括安装喷淋灭火系统、设置混凝土牺牲层、使用耐火纤维混凝土、粘贴隧道专用防火板、喷涂隧道专用防火涂料、喷射无机纤维防火护层材料,各种措施各有利弊。比较一下,发现喷涂防火涂料是性价比最高的防火方法。防火涂料通过机械喷涂于隧道的内壁及拱顶表面,火灾时起隔热保护作用,可有效防止隧道内钢筋混凝土在高温下强度降低,避免混凝土炸裂及衬砌内钢筋破坏失去支撑能力而导致隧道垮塌等。本文研究隧道防火涂料施工工艺,是为了更好地通过施工控制来发挥隧道防火涂料的优点,提高其耐火性能和使用效果。
