Field experiments require fewer tests, but they are more time-sensitive. Traditional screening experiments require that the samples be transported back to the laboratory for testing, and secondly, the screen needs to be cleaned again after each set of experiments before the next set of experiments. At present, there is no field screening device that can conduct fast and multiple experiments. Moreover, there are problems such as sample packaging breakage and long history between the collection of sand and soil samples on site and geotechnical testing, which in turn affects the accuracy of the experimental results.
[0003] At present, the existing screening and moisture content determination methods are: screening with a sifter in the laboratory; determination after drying in the laboratory. However, the above methods are all carried out in the laboratory, and timely and effective feedback of information cannot be achieved when the distance is long; and the moisture content in the sand and soil will be different during the transportation process, thus affecting the test results; in addition, the soil samples need to be poured out of the device after screening and drying, and some fine particles are easily overlooked, which affects the test results when weighing.
