Main purpose

    The portable rock direct shear instrument is developed in accordance with the national industry standards SL264-2001 and JTG E41-2005. The instrument adopts the flat push method and is mainly suitable for direct shear tests of rock blocks, structural surfaces (such as joint surfaces, layer interiors, sheet interiors, fissure surfaces, etc.), concrete (or mortar) and rock contact surfaces (bonding surfaces), as well as concrete and other materials bonding surfaces or overall shear strength tests. The machine has a simple, lightweight, intuitive structure, easy maintenance, and can be used in the field. The test data is displayed digitally, accurately and reliably.
