Airflow enhanced roadbed ventilation structure, composite roadbed structure and construction method of composite roadbed structure
The invention discloses an airflow-enhanced roadbed ventilation structure, a composite roadbed structure and a construction method of the composite roadbed structure. The composite roadbed structure comprises a roadbed, an airflow enhanced roadbed ventilation structure and a heat pipe system, the roadbed comprises a roadbed filler layer, a ventilation plate lower leveling layer, a ventilation plate upper cushion layer and a pavement structure layer which are sequentially arranged from bottom to top; a ventilation plate in the airflow enhanced roadbed ventilation structure is arranged between a lower leveling layer of the ventilation plate and an upper cushion layer of the ventilation plate; the heat pipe system comprises more than one heat pipe, and one end of each heat pipe is inserted into the roadbed from the roadbed slope and located below the ventilation plate. The composite roadbed structure provided by the invention has the advantages of resisting differential deformation of the roadbed and improving the rigidity of the roadbed through the ventilation plates, and meanwhile, the heat pipe system is used for controlling middle thaw collapse of the wide roadbed and reducing deep thaw collapse deformation of the frozen soil roadbed.
本发明揭示了一种气流增强型路基通风结构、复合路基结构及其施工方法。所述复合路基结构包括路基、气流增强型路基通风结构以及热管系统；路基包括从下向上依次设置的路基填料层、通风板下找平层、通风板上垫层和路面结构层；气流增强型路基通风结构内的通风板设置在通风板下找平层和通风板上垫层之间；热管系统包括一个以上热管，热管的一端从路基边坡插入路基内部，且位于通风板下方。本发明提供的复合路基结构，通过通风板提升抵抗路基差异变形、提升路基刚度的优势，同时通过热管系统控制宽幅路基中部融沉、减小冻土路基深部融沉变形。
