Background

Engineering geological prospecting is a geological research effort carried out to ascertain geological factors that affect the structure of an engineering. The results of geological survey field editing and survey soil sample indoor test are not only important basis for judging geological conditions, but also provide calculation parameters for design. These achievements affect both the project layout, project safety and project volume, and are related to construction costs, construction periods and the selection of optimal solutions. The importance of which is self evident.

The engineering classification and name fixing of soil are required in geological survey field editing and survey soil sample indoor tests, and for soil with main grain groups of sand grains, powder grains and clay grains of less than or equal to 2mm, the engineering classification and name fixing need to judge the fine grain content of the soil first and then perform other geotechnical tests according to the fine grain content. And the selection of the subsequent geotechnical test method can be influenced by the difference of the fine particle content. The existing judging method is to carry out a particle analysis test (screen analysis method) firstly, if the soil sample is the large-grained soil or the coarse-grained soil, the soil can be classified and named directly according to the result of the particle analysis test (screen analysis method). However, for fine-grained soil with more sand, other soil tests are needed to classify and name the soil. In this case, the particle analysis (sieving) test requires manpower and material resources, and may delay the work period. If the content of the fine particles in the soil sample is preliminarily judged according to experience, the related operators are required to have strong professional ability and rich experience, and the misjudgment cannot be completely avoided.

In addition, in the case of performing a geotechnical particle analysis (densitometry) test, it is necessary to sample and test a soil sample other than the fine-grained component in soil. In the existing method, a washing sieve with the aperture of 0.075mm is adopted to wash a soil sample, the operation is complicated, the loss of sand components is easily caused, and errors are generated.
