Description

Technical Field

[0001] The utility model relates to the technical field of soil mechanics testers, in particular to a mobile soil mechanics property tester. Background Art

[0002] In many fields such as soil science, agricultural engineering, geological exploration and civil engineering, accurate measurement and evaluation of soil mechanical properties are crucial. Soil mechanical properties, such as compressive strength, shear strength, deformation characteristics and temperature sensitivity, are directly related to soil stability, bearing capacity and feasibility of engineering applications. Before specific construction operations, it is usually necessary to test the soil mechanical properties. When performing testing operations, corresponding mechanical property testers are usually used.

[0003] There are many types of mechanical property testers on the market, but most of them are bulky and difficult to carry, which limits their application in the field or in complex terrain. In addition, the bottom of such mechanical property testers is generally supported directly by support pads, and lacks corresponding wheels, making it inconvenient to move. They cannot be directly moved to the corresponding location outside to perform multiple testing operations. As a result, each time a sample is taken, it is transported to the laboratory for testing. The test results of such sampling tests are not accurate enough, and the scope of use of the tester is limited, which brings inconvenience to users. In view of this, we proposed a mobile soil mechanical property tester. Utility Model Content
