The invention provides an energy underground structure model experiment testing system, comprising: a model unit, the model unit includes a model box filled with test soil and an energy underground structure model arranged in the test soil; a temperature loading unit, including A water tank, a water pump, a temperature cycle controller, and a heat exchange tube connected by pipelines in sequence, the heat exchange tube is built into the energy underground structure model; an air loading unit is used to apply different temperatures and Air fluid of / or speed; detection unit, including the temperature sensor array arranged in the test soil, the temperature sensor and the strain sensor arranged in the energy underground structure model, the temperature sensor and the strain sensor are respectively connected with The demodulator is connected, and the demodulator is connected with the computer. Compared with other model tests, the energy pile and energy tunnel can be tested separately, and the energy pile and energy tunnel can also be tested simultaneously.
Description
technical field [0001] The invention relates to the technical field of underground engineering structure model experiment testing, in particular to an energy underground structure model experiment testing system. Background technique [0002] As a new type of underground structure, the energy underground structure can combine the ground source heat pump heat exchange pipe network with the traditional underground structure. The interior of the underground structure provides space for the heat exchange pipes, does not occupy the underground area, saves land, and is relatively Compared with the ground source heat pump, the drilling link is reduced, and the grouting and backfilling process of the heat exchange well is also reduced. In addition, this technology reduces the project cost and shortens the construction time. Similar to the ground source heat pump, it also uses the flow of heat-carrying fluid in the heat exchange tube to achieve the purpose of heat exchange between t...
