丙烯酸盐喷膜防水材料在隧道力下的耐久性研究

Research on durability of acrylate spray-on waterproof membrane under mechanical circumstance in tunnel

隧道及地下工程中防水材料所处环境隐蔽,一旦失效,不仅难以修复,甚至不能被及时发现。因此,了解并掌握防水材料在隧道力环境下的耐久性乃至使用寿命具有重要的工程指导意义。根据隧道防水材料的受力特点,采用自行设计研制的试验装置进行研究,分别制定丙烯酸盐喷膜防水材料在挤压、拉伸及剪切状态下的耐久性指标。

Waterproof material used in tunnel and underground engineering is hard to be restored and even detected timely once this material is inactive. It is consequently very important to know the durability and even useful life of spray-on waterproof membrane under mechanical circumstance in tunnel to provide technical guidance for construction. This paper carried through the experimental research by equipment designed and made independently according to the stress characteristics of the waterproof material for the tunnel,and established durability norm of acrylate waterproof membrane under the conditions of pressure,tension and shearing force.
