Automatic Coarse Soil Rock Sand Direct Shear And Triaxial Test Apparatus This product is used to test and analyze the stress-strain relationship, deformation and strength characteristics of coarse grained soil under triaxial unequal stress conditions, and to study the numbering rule of deviatoric stress, volumetric strain and internal friction angle with S2 coefficient of intermediate principal stress. Because the conventional triaxial only considers the stress in S1 and S3 directions, and does not consider the influence of the intermediate principal stress, it cannot truly reflect the stress characteristics of the soil mass. In order to obtain the actual stress state of coarse-grained soil in the project, only through the true triaxial testing machine can the triaxial unequal stress be applied to the coarse-grained soil sample, and the actual stress characteristics of the land can be truly and accurately reflected.

Standard: EN 1097-2, Also conforming to NF P18-573, UNE 83 114, UNI 8520-19, CNR No. 34, ASTM C131 Los angeles abration machine consists of a rolled steel drum having an inside diameter of 710 mm and internal length 510 mm. The drum is rotated by a speed reducer driven by an electric motor at a speed of between 30 and 33 r.p.m. The machine is equipped with an automatic counter, which can be preset to the required number of revolutions of the drum. The unit is supplied with the abrasive charge.

Cylinder speed 100±5 tr/min. After testing,automatic interruption of engine operation. 3.It applies European/French standards.

IWIN-FKY crack width tester is used to measure the crack width in concrete buildings such as houses, roads and Bridges.

The microcomputer servo rock triaxial testing machine is a testing equipment used in the field of rock mechanics to study the mechanical properties and shear properties of rocks in various environments. This machine can automatically complete the triaxial compression test of rocks. The rock triaxial instrument mainly consists of a high-stiffness host machine, a pressure self-balancing triaxial pressure chamber, a supercharger, a servo hydraulic source, an axial loading and control device, a confining pressure loading and measurement control, a pore water pressure loading and measurement device, and a temperature It is composed of measurement system and device, computer measurement and control system and other parts.

STC (-1F/1MF) series automatic pneumatic consolidation instrument uses the latest technology, integrating mechanical technology,electronic technology, automatic control technology, sensor automatic detection technology and computer technology. Through the automatic control of microcomputer, the functions of automatic loading and unloading operation and automatic data collection are realized, which makes the test control more accurate and efficient, and can completely replace the traditional lever-type consolidation instrument. The test process is controlled by computer, and the performance of the instrument has comprehensively exceeded that of domestic similar instruments, and has reached and approached international similar products.
