DLY-3 Coarse-Grained Soil Triaxial Shear Testing Machine

Description

Product Introduction:

In compliance with GB/T 50123-2019 “Standard for Geotechnical Test Methods” and DL/T 5356 “Test Procedure for Coarse-Grained Soils in Hydropower and Water Conservancy Projects,” this test method is applicable to the determination of coarse-grained soils with particle sizes not exceeding 60 mm. It is used for conducting unconsolidated undrained shear tests (UU), consolidated undrained tests (CU), consolidated undrained shear tests with pore pressure measurement, and consolidated drained shear tests (CD).

Key features:

1. The microcomputer control system enables testing, graphing, analysis, report generation, and more.

2. Real-time display of axial load, displacement, confining pressure, pore pressure, and volumetric strain.

3. Independent development of the Mites coarse-grained soil software system

4. Adopts a four-column structure for stable performance.

5. Uses a spoke-type axial sensor.

6. Top-mounted hydraulic cylinder saves space

7. Equipped with a transparent observation window

8. The lifting and trial‑drum device is a double‑column hydraulic type, which saves space at the front column position.
