Abstract

The invention discloses a geothermal energy collection pavement, and relates to the technical field of geothermal energy utilization. The pavement comprises a cushion layer, a first base layer and a surface layer, the cushion layer is a cement macadam layer, the first base layer is a graphene composite filler layer, the surface layer is an asphalt concrete layer, the first base layer is located between the cushion layer and the surface layer, a heat conduction pipe is laid in the first base layer, the heat conduction pipe is composed of a first heat conduction pipe and a second heat conduction pipe which are communicated, the first heat conduction pipe is located in the base layer, the two ends of the first heat conduction pipe extend out of the first base layer and are communicated with the second heat conduction pipe, the end of the first heat conduction pipe is connected with the end of the second heat conduction pipe through a connector, the second heat conduction pipe is communicated with a geothermal pump and a heat collector, and the first heat conduction pipe, the second heat conduction pipe, the geothermal pump and the heat collector form a closed circulation channel. The graphene composite material is used as a base layer filler to improve the heat transfer and heat storage of the filler and improve the bearing capacity of the base layer. The ground source heat pump technology is used for adjusting the temperature of each layer of the pavement and improving the pavement stability.

Description

technical field [0001] The invention relates to the technical field of geothermal energy heat utilization, in particular to a geothermal energy collection road surface. Background technique [0002] Existing pavements are generally composed of a second base layer, a base layer, and a surface layer. According to the different functions of each layer, the second base layer, base layer, and surface layer are usually composed of different materials to meet different use requirements. [0003] However, the pavement not only bears the wheel load, but also is affected by natural environmental factors. If the temperature is too high in summer, the road surface will be exposed to the scorching sun, which will cause the temperature of the pavement layer to be too high, and even melt and cause the road surface to become soft. In winter, the temperature is too low, and the road surface is icy due to the low temperature, which occurs from time to time. In this way, under the influence ...
