Frost heaving resistant roadbed system and roadbed heat supply method
The invention provides an anti-frost heaving roadbed system and a roadbed heat supply method, and relates to the technical field of railway roadbed maintenance equipment. The frost heaving resistant roadbed system comprises a roadbed body, a heat dissipation device and a geothermal energy device, the heat dissipation device is embedded in the roadbed body, and the geothermal energy device is arranged underground at the position where the roadbed body is located and used for collecting geothermal energy; a circulation pipeline is arranged between the heat dissipation device and the geothermal energy device, a heating medium is arranged in the circulation pipeline, and the circulation pipeline is used for transmitting heat collected by the geothermal energy device to the heat dissipation device. Based on the technical scheme, when the environment temperature of the railway roadbed is too low, the geothermal energy device collects the geothermal energy and dissipates heat to the roadbed body through the heat dissipation device to heat the roadbed body, so that the temperature of the railway roadbed is increased, and frost heaving is avoided.
本发明提供了一种抗冻胀路基系统及路基供热方法，涉及铁路路基维护设备技术领域。该抗冻胀路基系统包括路基本体、散热装置以及地热能装置，散热装置嵌设于路基本体内，地热能装置设置于路基本体所在位置的地下，其用于收集地热能；散热装置与地热能装置之间设置有循环管路，循环管路中具有热媒介质，循环管路用于使地热能装置收集的热量传递至散热装置处。基于本发明的技术方案，当铁路路基的环境温度过低时，地热能装置收集地热能并通过散热装置向路基本体散热，对路基本体进行加热，以使铁路路基的温度升高，避免冻胀。
