Composite roadbed structure and composite roadbed structure construction method
The embodiment of the invention provides a composite roadbed structure and a composite roadbed structure construction method, and relates to the technical field of cold region road and bridge construction, and the composite roadbed structure comprises a roadbed unit, a phase change heat preservation unit and a heat pipe unit. The phase change heat preservation unit is arranged in the roadbed unit; the heat pipe unit comprises a heat pipe body and a heat dissipation pipe body, the heat pipe body is embedded in the roadbed unit and located below the phase change heat preservation unit, the heat dissipation pipe body is connected to the heat pipe body, and the heat dissipation pipe body extends out of the roadbed unit. The heat pipe body is used for being filled with a volatile working medium, and the volatile working medium is used for volatilizing when heated, flowing to the heat dissipation pipe body, condensing after being cooled at the position of the heat dissipation pipe body and flowing back into the heat pipe body. According to the design of the roadbed structure, the long-term thermal stability of the roadbed can be effectively improved, the problems of excessive concentrated refrigeration of a traditional heat pipe, cavities around the pipe and the like are solved, annual dynamic cooling and heat preservation of the roadbed are achieved, and technical support is provided for high-quality construction and safe operation of road engineering in the cold region.
本申请实施例提供了一种复合路基结构和复合路基结构施工方法，涉及寒区路桥施工技术领域，其包括路基单元、相变保温单元和热管单元。相变保温单元设于路基单元内；热管单元包括热管本体和散热管体，热管本体埋设于路基单元内且位于相变保温单元下方，散热管体连接于热管本体，散热管体伸出路基单元外。热管本体用于填充易挥发工质，易挥发工质用于在受热时挥发并流向散热管体，且在散热管体处受冷后冷凝并回流至热管本体内。该路基结构的设计，能够有效提升路基的长期热稳定性、避免传统热管过度集中制冷的问题和管周空洞等问题，并实现路基全年动态冷却与保温，为寒区道路工程高质量建设与安全运营提供技术支撑。
