 I. Overview

YUC.IJZQY32-1 intelligent air pressure type direct shear preloading instrument is a new type of indoor geotechnical test instrument which is specially designed to provide soil sample preloading work for geotechnical direct shear test. It can automatically complete the loading and unloading of pressure during the preloading test by using the modern technology of mechanical electronics, sensor detection, automatic control and computer intelligence. Its pressure source adopts the air pressure way, is stable and reliable, may completely replace the lever type preloading instrument and so on early product.

 The instrument can apply vertical pressure to the soil sample, so that the soil sample drainage is stabilized and then the direct shear test is carried out. The instrument exerts vertical pressure on soil samples through a high-precision pressure control system, which can be pre-prepared for 4 or more specimens at a time.

 Using computer automatic control technology, the instrument can greatly improve the efficiency of direct shear test and reduce the labor strength of the test personnel.

The instrument has the characteristics of high working efficiency, compact structure, light weight, convenient operation and stable performance.
