高速公路隧道一旦发生火灾,施救难度极大,将造成重大人员伤亡和隧道结构的破坏。为保证高速公路隧道安全、高效运行,加强隧道防火涂料的施工控制,有着重大的社会经济价值。但目前高速公路隧道防火涂料施工工艺尚不太成熟,也无可供参考的施工技术规范。本文通过青临高速公路穆陵关隧道防火涂料的施工,介绍了公路隧道施工中常见的质量问题及质量控制措施,可供类似工程参考。
In the event of a fire in an expressway tunnel, it will be extremely difficult to rescue the tunnels, which will result in heavy casualties and damage to the tunnel structure. In order to ensure the safe and efficient operation of expressway tunnels, it is of great social and economic value to strengthen the construction control of tunnel fireproof coatings. However, the current highway tunnel fire retardant coating construction technology is not yet mature, there is no reference for the construction of technical specifications. This paper introduces the quality problems and quality control measures commonly used in the construction of highway tunnels through the construction of fireproof coatings on the tunnels of Mulingguan in Qinglin Expressway, which can be used for reference for similar projects.
