CCCC First Harbor Engineering Co., Ltd. has completed debugging training for the thin-walled lining bucket cross plate shearing instrument

On June 10, 2019, the thin-walled lining bucket cross plate shearing instrument customized by CCCC First Harbor Engineering Co., Ltd. completed debugging training and was delivered for use.
This instrument is customized based on the original desktop cross plate shear tester, allowing it to perform cross plate shear tests on the undisturbed soil retrieved from thin-walled lined barrels. The traditional indoor cross plate shear test can also be completed by replacing the base and sample cylinder.
The detailed information of the instrument is as follows. New and old customers are welcome to consult and exchange ideas.

The desktop cross plate shear tester is an indoor geotechnical testing instrument used to determine the undrained strength (Cu) of soft soil or sensitive clay. It can measure the undrained strength of undisturbed soil taken at different depths. The instrument uses a fixture to fix the soil sample in the middle of the rack, and rotates the handle to allow the cross plate head to penetrate the soil sample for shear testing.

Main technical indicators

1. Cross plate specifications: 12.7mm (diameter) x 25.4mm (height), 25.4mm (diameter) x 50.8mm (height), and 38.1 (diameter) x 76.2mm (height). Sizes can also be customized according to user requirements;
2. Torque sensor: 0-30 N · m, accuracy 0.3% F.S, resolution 0.1 N · m, adjustable range according to user requirements;
3. Shear rate: 0.001-180 degrees/min, continuously variable speed;
4. Equipped with a 480 * 270 high-definition LCD touch screen, real-time display of torque, cutting angle and other data, matched with touch buttons to control operation, can be controlled by touch keyboard or software; High speed network communication interface and computer communication; Real time data is stored in the collector and can be run offline;
5. The collection and processing software supports the Windows 8/10 operating system, with fully automatic collection and control. Data can be exported to Excel files, and shear strength curves of soil samples at different depths can be drawn and strength values calculated;
