Abstract

The invention discloses a vertical buried pipe heat exchanger for preventing roadbed frost heave. The vertical buried pipe heat exchanger for preventing roadbed frost heave comprises a heat rising mechanism, heat release assemblies respectively connected to the two ends of the heat rising mechanism, and a refrigeration heat exchange mechanism connected to the lower end of the heat rising mechanismthrough a heat transmission pipeline and communicating with the heat release assemblies. The heat release assemblies comprise double-layer heat exchange pipe assemblies connected to the two ends of the heat rising mechanism respectively, gas-liquid separators connected to the double-layer heat exchange pipe assemblies and branch pipes connected between the gas-liquid separators and the refrigeration heat exchange mechanism. The vertical buried pipe heat exchanger for preventing roadbed frost heave is simple in structure, of an assembled structure overall, convenient to transport and construct, low in manufacturing cost, reliable in use, uniform in heat dissipation, good in heat exchange effect and high in heat exchange efficiency.

Description

technical field [0001] The invention relates to the technical field of ground source heat pump heat exchangers, in particular to a vertical buried tube heat exchanger for preventing frost heaving of roadbeds. Background technique [0002] In my country, permafrost reaches 2.15 million square kilometers, which has an important impact on the construction and later operation of railways or highways. In winter, because the density of water is higher than that of ice, in the frozen state, the frozen soil is like ice, and the volume expands during the condensation process, and the upper roadbed or steel rail is jacked up due to the expansion. In summer, the permafrost thaws and shrinks in size, and in winter, the raised roadbed or steel rails descend with the thawing of the permafrost. The repeated freezing and thawing of permafrost will cause serious deformation or damage to the subgrade, and even muddy and muddy discharge, and the rails will have wavy ups and downs, posing a th...
