portable multi-function rock direct shear apparatus

1.Main purpose and scope of application
    YZJ-30 portable rock direct shear apparatus is researched and developmented according to national industry standard 《Highway Enfineering Rock Test Procedures》（JTG  E41-2005）《Water Resources and Hydropower Engineering Rock Testing Procedures》（SL264-2001）,applying for rock structural plane(such as joint surface ,layer inside,the chip inside, the cleavage planes) 、rock and the connection surface of concrete or motar with rock shear testing .as well as the shear surface between concrete and other materials anti-shear strength testing.

    Its structural performance in full compliance with regulatory requirements of pushing test.
