Body temperature rheometer

The present invention is a strain gauge body temperature, the shaft includes an outer chamber and the inner chamber shaft, the outer shaft and inner shaft chamber buckle chamber are mounted on the base. Equipped with the base end of the outer pipe 5 communicates with the outside, where the two ends of the inner pipe communicates with the outer shaft interior, the inner end of the inner shaft and the interior of the pipe 3 communicates. The top of the inner shaft chamber has a measured pressure pipe; the base is provided with an outer Piezometric. In the central position of the base is formed with a boss, the experimental soil samples mounted on bosses. The inner shaft and outer piezometric pressure differential signals to the computer to read through a differential pressure sensor. And implemented by applying a reverse pressure compressor and the sensors measure soil pore water pressure in function of soil samples. Can accurate simulation under low temperature or temperature variations of the present invention, the case of soil samples by force while being able to accurately measure the volume of the soil sample during the experiment changes in permafrost research volume change for cold area and asked the foundation, roadbed construction Give suggestion.
