Problems solved by technology

There are differences in the weathering environment, transport and deposition dynamic conditions in different geological periods and regions. Therefore, the soil is not only complex in engineering properties, but also has strong regional and individual properties. The samples in engineering research need sampling devices. Sampling in the field, followed by experimental research, but the existing sampling device is easily affected by the environment and the ground when it is used, so the sampling cannot be carried out smoothly, and the final result of the experiment is easily affected by pollution when the sampling sample is taken out

Abstract

The invention discloses a sampling device for geotechnical engineering investigation and a using method thereof. The sampling device comprises a work fixing table and an upper positioning sleeve, an upper sampling stress rod is movably connected to the interior of the upper positioning sleeve, a handle connecting rod is fixedly connected to the upper portion of the upper sampling stress rod, and sampling stress handles are fixedly connected to the upper portion of the handle connecting rod; antiskid silicon rubber sleeves are arranged at one ends of the sampling stress handles; two groups of sampling stress handles and two groups of antiskid silicon rubber sleeves are arranged, the antiskid silicon rubber sleeves are fixedly connected to the surfaces of the sampling stress handles at the two ends, and an upper fixing rod is fixedly connected to the outer side of the lower part of a working fixing table; an adjusting and positioning rotating shaft is arranged below the upper fixing rod,and a lower fixing rod is arranged below the adjusting and positioning rotating shaft; the sampling device for geotechnical engineering investigation can be conveniently used, the whole device can berapidly and stably fixed and installed, dismounting and storage for preventing sample pollution after sampling are also very convenient, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a sampling device for geotechnical engineering investigation and a use method thereof. Background technique [0002] Geotechnical engineering is a new technical system established in the practice of civil engineering in European and American countries in the 1960s. Geotechnical engineering is to solve rock mass and soil engineering problems, including foundation and foundation, slope and underground engineering, etc., as its own research object. Geotechnical engineering is a branch of civil engineering. Mechanics and Rock Mechanics is the science that solves engineering technical problems related to rock and soil in various projects. According to the division of engineering construction stages, the work content can be divided into: geotechnical engineering survey, geotechnical engineering design, geotechnical engineering treatment, geotechnical engineering monit...
