Stable frost heaving prevention heat gathering device and roadbed thereof
The invention provides a stable frost heaving prevention heat gathering device and a roadbed thereof, and relates to the technical field of disease prevention and control of engineering construction in a seasonal frozen soil region. The stable frost heaving prevention heat gathering device comprises a solar heat absorption box, a circulating power unit, a heat gathering pipe and a circulating pipe, the circulating power unit comprises a solar photovoltaic panel, a temperature controller and a circulating pump which are electrically connected in sequence, and the solar heat absorption box, the heat gathering pipe and the circulating pump communicate end to end in sequence through the circulating pipe to form a circulating loop. The heat gathering pipe is used for being inserted into the roadbed, a first temperature sensor is used for detecting the temperature T1 of the solar heat absorption box, a second temperature sensor is used for detecting the temperature T2 of the heat gathering pipe, and the temperature controller is used for conducting current under the condition that T1 is larger than T2. According to the stable frost heaving prevention heat gathering device, solar energy resources can be utilized, balanced and flat heating of the roadbed is achieved through roadbed temperature field flat heating and key regulation and control over the portions, prone to frost heaving, of the roadbed, and project diseases such as frost heaving and uneven fluctuation of the roadbed in the seasonal frozen soil area are effectively avoided.
本发明提供一种稳定式防冻胀聚热装置及其路基，涉及季节冻土区工程建设病害防治技术领域。稳定式防冻胀聚热装置包括太阳能吸热箱、循环动力单元、聚热管和循环管，其中，循环动力单元包括依次电连接的太阳能光伏板、温度控制器和循环泵，太阳能吸热箱、聚热管和循环泵通过循环管依次首尾连通、形成循环回路，聚热管用于插入路基中，第一温度传感器用于检测太阳能吸热箱的温度T1，第二温度传感器用于检测聚热管的温度T2，温度控制器用于在T1＞T2的条件下导通电流。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。
