Power type frost heaving heat accumulation self-protection device and roadbed
The embodiment of the invention provides a power type frost heaving heat accumulation self-protection device and roadbed, and relates to the technical field of disease prevention and control of engineering construction in a seasonal frozen soil region. In the device, a solar heat absorber, a heat accumulating pipe, a forward pump and a reverse pump are sequentially connected end to end through a circulating pipe to form a circulating loop, the circulating loop is filled with a circulating working medium, the solar heat absorber is used for being installed outside the roadbed, the heat accumulating pipe is used for being inserted into the roadbed, the forward pump is used for pushing the circulating working medium to circularly flow in the circulating loop in the forward direction, and the reverse pump is used for pushing the circulating working medium to reversely flow in the circulating loop, so that the circulating working medium in the solar heat absorber is emptied. According to the device and the roadbed, balanced and flat heating of the roadbed can be achieved, engineering diseases such as frost heaving and uneven fluctuation of the roadbed in the seasonal frozen soil region are effectively avoided, and the situation that the stability and sealing performance of the device are affected by the fact that the circulating working medium reaches the boiling point in summer can be avoided by controlling the position of the circulating working medium.
本发明的实施例提供了一种动力式冻胀聚热自保护装置及其路基，涉及季节冻土区工程建设病害防治技术领域。该装置中，太阳能吸热器、聚热管、正向泵和逆向泵通过循环管依次首尾连接，形成循环回路，循环回路中填充有循环工质，太阳能吸热器用于安装在路基的外部，聚热管用于插入路基，正向泵用于推动循环工质在循环回路中正向循环流动，逆向泵用于推动循环工质在循环回路中逆向流动，以使太阳能吸热器中的循环工质排空。该装置和路基不仅能够实现路基均衡、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，还能够通过控制循环工质的位置，避免夏季循环工质达到沸点影响装置的稳定性和密封性。
