Embodiment Construction
[0018] Below in conjunction with accompanying drawing, the present invention is described further:
[0019] Such as figure 1 As shown, a device for testing the characteristics of hydrothermal changes in the freezing and thawing process of aqueous porous media is composed of a model outer box 1, an outer box top cover 2, a refrigeration coil 3, a cold bath liquid interface 4, a sensor lead hole 5, Outer box base 6, model inner box 7, inner box base 8, inner box top cover 9, sealing ring 10, lead pipe 11, fastening bolt 12, catheter 13, 1# cold bath 14, 2# cold bath 15 , cold bath liquid 16, filling liquid 17, temperature sensor 18, moisture sensor 19, water potential sensor 20, data acquisition instrument 21 and electronic computer 22 composition. Model inner box 7 and model outer box 1 can be cuboid or cylinder. The length of each side of the cuboid and the diameter and height of the cylinder are not less than 0.60 m, the length of each side and the diameter and height of th...
