Embodiment Construction

[0052] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0053] Test device such as figure 1 As shown, it includes two parts: the constant temperature heating system and the test soil column. During the test, the test tank was filled with red clay, silty clay and fine sand for construction from the ground source heat pump test site respectively, and one end of the soil column was heated through a copper heating tank, and the embedded sensors were used to measure the temperature of each measurement in the soil column. point temperature and humidity changes.

[0054] Constant temperature heating part:

[0055] In order to provide a stable constant temperature heat source for the whole test bench, the constant temperature water tank 1 of the present invention: the box body is a 20L vehicle-mounted incubator, the built-in electric heater 2 is connected to the external temperature controller 3, and th...

Abstract

The invention discloses a one-dimensional soil body heat and humidity transfer simulation device and measurement method. Two electric heaters are arranged in a thermostatic water tank; the thermostatic water tank is also internally provided with a first circulating water pump used for carrying out internal circulation on water in the water tank, and a second circulating water pump used for carrying out external circulation on hot water in the thermostatic water tank by a pipeline; the thermostatic water tank is also internally provided with a water thermometer used for measuring the water temperature; a soil column experiment box body is made of an acrylic plate capable of insulating heat and water; a heating tank is arranged at one end in a soil column experiment box and the rest of space in the soil column experiment box is used for bearing soil used for an experiment; a plurality of temperature sensors and moisture content sensors are also arranged in the soil used for the experiment in the soil column experiment box; the heating tank is isolated from the soil used for the experiment by a copper plate. The one-dimensional soil body heat and humidity transfer simulation device and measurement method have the beneficial effects that disturbance is not caused when a soil body is measured, and the device is good in integrity and high in test accuracy.

Description

technical field [0001] The invention belongs to the technical field of environmental rock and soil measurement, and relates to a simulation device and a measurement method for one-dimensional heat and moisture transfer of soil. Background technique [0002] As a porous medium, soil is generally composed of solid (soil particles), liquid (water), and gas three-phase substances. It is in a certain atmospheric environment, and under the combined action of various transport mechanisms, it will produce Migration of heat, water and air. In the natural environment, the heat-moisture migration process of soil is controlled by various effects, and its influencing factors include soil temperature, pressure, relative content of liquid phase and gas phase in soil, porosity and soil type, etc. Therefore, soil in nature The heat and moisture migration process is a complex energy exchange and material flow process under the interaction of the above factors, which has become a key content ...
