This is a specialized piece of equipment used in geotechnical testing, primarily for the preloading and shaping of specimens before the shear test in soil mechanics. It is typically used in conjunction with a geotechnical shear apparatus to improve testing efficiency and the reliability of test data.

Sixteen-unit fully automatic pneumatic direct shear Pre-Pressing Equipment

Model:TGSYL-1

I.Product Introduction

This equipment is a specialized device for geotechnical testing,used for preloading soil samples before direct shear tests to ensure that the soil sample reaches the required consolidation state before the shear test.It is mainly used in geotechnical engineering,geological exploration,highway and railway construction and other fields.It is suitable for pre-compression consolidation tests of samples such as cohesive soil and fine-grained soil.
