Prefabricated tunnel asphalt pavement structure and assembly process thereof
The invention discloses a prefabricated tunnel asphalt pavement structure and an assembly process thereof. The prefabricated tunnel asphalt pavement structure comprises a prefabricated layer, a bonding layer and a flame-retardant asphalt concrete wearing layer which are sequentially paved from bottom to top, the prefabricated layer comprises a plurality of prefabricated pavement sections which are spliced in the length direction of the pavement; a seamless expansion joint is bonded between every two adjacent prefabricated pavement sections; each prefabricated pavement section comprises a lane plate, a waterproof bonding layer and a prefabricated asphalt pavement layer which are sequentially paved from bottom to top; the seamless expansion joint is an epoxy asphalt concrete seamless expansion joint. The prefabricated pavement sections can be prefabricated in a factory and spliced on site, and splicing seams are filled with seamless expansion joints, so that the construction efficiency and quality are improved, the construction period is shortened, the investment of constructors and equipment is reduced, the construction cost and the maintenance cost are reduced, and the use performance and safety of the tunnel pavement are improved. And for areas with severe construction environments, the tunnel construction efficiency and safety can be greatly improved, and the rapid construction requirement of urban tunnels is met.
本发明公开了一种可预制式隧道沥青路面结构及其装配化工艺，包括从下至上依次铺设的预制层、粘结层和阻燃沥青混凝土磨耗层；预制层包括沿路面长度方向拼接的若干个预制路面节段；相邻两个预制路面节段之间粘结有无缝伸缩缝；每个预制路面节段均包括从下至上依次铺设的车道板、防水粘结层和预制沥青路面层；无缝伸缩缝为环氧沥青混凝土无缝伸缩缝。本发明能使预制路面节段在工厂预制，在现场拼接，拼接缝处填充无缝伸缩缝，不仅提高施工效率和质量，缩短施工周期，减少施工人员和设备投入，降低施工成本和维护费用，提高隧道路面的使用性能和安全性。对于施工环境恶劣地区，能大大提高隧道建设效率和安全性，满足城市隧道的快速建设需求。
