Soil in-situ borehole shear tester

Soil in-situ borehole shear testerIt is an instrument used for on-site measurement of soil shear strength, which can obtain soil mechanics parameters that are closer to reality without disturbing or minimally disturbing the soil

Usually, indoor direct shear or triaxial tests are used to determine the shear strength index of soil, which require several hours or even days for testing. Moreover, through on-site sampling, sample production, and other processes, there is a significant disturbance to the soil, and the test results differ greatly from the actual results

The testing process using BST in-situ shearing instrument only takes 30-60 minutes, and the test results can be obtained immediately after the test. Moreover, it is conducted on-site drilling testing, which minimizes soil disturbance and makes the test results closer to the actual results.

This device is widely used in highways, railways, airports, ports, tunnels, bridges, and industrial and civil buildings. It is commonly used in the design of various engineering facilities such as retaining walls, pile sheet walls, slope stability, and foundation, such as soil pressure calculation, slope stability assessment, landslide thrust calculation, stability of railway and highway soft soil foundation, calculation of foundation bearing capacity, etc

☆ On site measurement of drainage shear strength index of soil

☆ On site measurement of soil effective stress C 'and effective internal friction angle φ' values ☆ Can measure residual effective shear strength

☆ Testing is simple and fast, the testing process only takes 30-60 minutes

☆ Originating from the University of Iowa in the United States

☆ Complies with ASTM D18.02 standard

Suitable for testing various types of soil such as soft and hard soils

Widely used: foundation bearing capacity, landslide assessment, retaining wall
