Tunnel pavement structure capable of preventing water damage
The invention discloses a tunnel pavement structure capable of preventing water damage. The tunnel pavement structure sequentially comprises a composite porous permeable asphalt pavement layer, an asphalt macadam layer, a graded macadam layer, a leveling layer, a double waterproof layer, a three-dimensional porous steel fiber concrete layer and a base layer from top to bottom; a plurality of waterseepage drainage pipes longitudinally distributed along the pavement structure are arranged along two ends of a tunnel pavement; seeping water in the pavement structure is guided into water collection systems at the two sides of a road through drainage pipes, a reinforcement layer is arranged in the composite porouspermeable asphalt pavement layer and is of a composite honeycomb structure, the composite honeycomb structure is composed of a plurality of composite honeycomb hole units, and raw materials of the double waterproof layers comprise methacrylic resin, propylene oxide polyether and the like. A waterproof layer and a water diversion channel are arranged between the layers of the pavement structure, so that surface water seepage and underground upward water seepage can be effectively blocked, and damage of water on the tunnel pavement is avoided in a mode of combining prevention, drainage, interception and blockage.
本发明公开了一种防水损害破坏的隧道路面结构，由上至下依次包括复合多孔透水性沥青路面层、沥青碎石层、级配碎石层、调平层、双重防水层、三维多孔钢纤维混凝土层和基底层，沿隧道路面两端设置多个沿路面结构纵向分布的渗水引流管，引流管将路面结构内渗水引入道路两侧集水系统，所述复合多孔透水性沥青路面层内设置有增强体层，所述增强体为复合蜂窝结构，复合蜂窝结构由多个复合蜂窝孔单元构成，所述双重防水层原料包括甲基丙烯酸树脂、环氧丙烷聚醚等；通过在路面结构的层间设置防水层和引水通道，能够将地表渗水和地下上上渗水进行有效的阻隔，以防、排、截、堵相结合的方式避免隧道路面水损害破坏。
