Coarse-Grained Soil Direct Shear And Compression Testing Machine (Integrated Machine)

Product introduction

ZY50-5C coarse-grained soil direct shear and compression testing machine (integrated machine) conforms to the national standard of the People's Republic of China GB/T 50123-2019 "Soil Test Regulations" and group standard T/CHES 29-2019 "Coarse-grained Soil Test Rules" and DL/T5356-2006 "Coarse-grained Soil Test Rules for Hydropower and Water Conservancy Projects" are used to determine the shear strength and consolidation deformation of coarse-grained soil, according to which the relationship between shear strength and pressure can be determined, and the relationship between coarse-grained soil deformation and pressure can also be determined after replacing the compression parts. The relationship between deformation and time. In order to calculate the shear strength, unit settlement, compression coefficient, compression index, rebound index, volume compression coefficient, compression modulus, consolidation coefficient and pre-consolidation pressure of coarse-grained soil.
