C062 Manual hydraulic rock direct shear box apparatus
Rock hydraulic direct shear instrument is a new type of rock mechanical property test instrument developed and produced by our company. The instrument is a group of rock specimens of the same type subjected to horizontal shear under different normal loads, and the rock is determined according to the expression of Coulomb's law. Shear strength parameters. It is suitable for direct shear test of rock structural surface (such as joint surface, bedding surface, flaky surface, splitting surface, etc.), rock itself, and concrete or mortar and rock cemented surface.
This instrument is suitable for cutting the rock and non-metallic materials into cylindrical and rectangular regular shapes for shear strength test.
This type uses a manual hydraulic pump to pressurize, the normal and shear loading intensity values of the hydraulic pump instrument read the MPa value, and select the kN value through the calibration conversion table. Normal and shear displacements are read manually by a dial indicator. It is mainly composed of normal loading device, horizontal shear loading device, shear box, and displacement device (optional) accessories.
