Air self-circulation unpowered heating device and roadbed thereof
The embodiment of the invention provides an air self-circulation unpowered heating device and a roadbed thereof, and relates to the technical field of seasonal frozen soil area engineering construction. The air self-circulation unpowered heating device comprises a heat collection header, a solar heat absorption box and a heat concentration pipe, wherein the heat collection header is used for being installed outside the roadbed; one end of the solar heat absorption box is inserted into the heat collection header; the solar heat absorption box is used for absorbing solar energy and transferring heat to the heat collection header; the heat concentration pipe comprises a heat absorption section and a heat releasing section which are communicated with each other; the heat absorption section is inserted into the heat collection header; the heat releasing section is used for being inserted into the roadbed; the heat absorption section is used for absorbing heat of the heat collection header and transferring the heat to the heat releasing section; and the heat releasing section is used for heating the roadbed. According to the device, solar energy resources can be utilized, and balanced and flat heating of the roadbed is achieved through flat heating of a ground temperature field of the roadbed and key regulation and control over the parts, prone to frost heaving, of the roadbed, so that engineering diseases such as frost heaving and uneven fluctuation of the roadbed in the seasonal frozen soil area are effectively avoided.
本发明的实施例提供了一种空气自循环无动力加热装置及其路基，涉及季节冻土区工程建设技术领域。空气自循环无动力加热装置包括集热联箱、太阳能吸热箱和聚热管，其中，集热联箱用于安装在路基的外部；太阳能吸热箱的一端插入集热联箱内，太阳能吸热箱用于吸入太阳能、并传热至集热联箱；聚热管包括相互连通的吸热段和放热段，吸热段插入集热联箱中，放热段用于插入路基中，吸热段用于吸收集热联箱的热量并传递至放热段，放热段用于加热路基。该装置能够利用太阳能资源，通过路基地温场平整加热、路基易冻胀部位重点调控，实现路基均衡、平整加热，有效避免季节冻土区路基冻胀、不均匀起伏等工程病害的产生。
