LIGHT-CONCENTRATING ANTI-FROST ANTI-HEAVE HEAT GATHERING DEVICE AND SUBGRADE THEREOF
The invention provides a light-concentrating anti-frost anti-heave heat gathering device and subgrade thereof. The device comprises a light concentrator mounted outside a subgrade; and a heat gathering tube comprising a heat absorption section and a heat release section in communication, the heat absorption section is inserted inside the light concentrator for transferring absorbed heat to the heat release section, the heat release section is inserted inside the subgrade for heating the subgrade, the light concentrator is configured to focus sunlight to and heat the heat absorption section. The heat gathering device herein takes advantage of solar energy resources, by smoothly heating the ground temperature field of the subgrade, and regulating the frost-heaving portions of the subgrade, balanced and smooth heating of the subgrade can be achieved and engineering diseases such as frost heave and uneven fluctuation of the subgrade in the seasonally frozen ground region can be effectively avoided.
