Background

Geotechnical engineering is a new technical system established in civil engineering practice in 60's of the 20 th century in the countries of the Europe and the America. Geotechnical engineering is to solve the problems of rock and soil engineering, including foundation and foundation, slope, underground engineering and the like, and is used as a research object of the geotechnical engineering. Soil sampling refers to a method for collecting soil samples, and comprises sampling arrangement and sampling technology. The sampling of the soil sample in the cross section is performed after the cross section observation is completed. Before sampling, the section should be trimmed and cleaned, the most superficial layer of the floating soil is cut off, and then the sample is taken from the central typical part layer by layer from top to bottom according to the layers.

Geotechnical engineering carries out the in-process of reconnoitring the ground, needs to gather soil sample and carries out the testing and analysis to the ground, uses conventional instrument at the in-process of sampling to take a sample, and current collection system is exactly with the sampling sword deepening in the ground, draws out a 20 cm's ground core, and work efficiency is lower, is difficult for taking out the sample, can not observe inside structure moreover, and the sample of taking out is loose, and the sample is very easily damaged in the transportation.
