SU1217983A1 - Device for sheat testing of soil - Google Patents

Description

one

The invention relates to a no-geological study of construction, in particular a framework for determining the strength of the soil.

  The aim of the invention is the exact vertical alignment in the plane of the slice by registering it in the soil treatment.

The drawing shows the test of the soil for a shearing, ny incision.

The device for testing the shear includes a working table 1, a frame 2, a fixed holder 3, a movable holder 4, which interacts through bearings 5 with the base 6. In addition, the device is equipped with a support made in the form of rods 7 with load cells 8 placed desktop and interacting with base 6,

The device works in the following way.

The stationary holder 3 is mounted on the frame 2, and the movable 4 on the base 6. The holder 3 and 4 are centered one relative to the other. Inside the clips 3, 4 place a soil sample. By means of the mechanism of the vertical load on the soil sample, a vertical pressure is created, and by means of the mechanism of the horizontal load ia, the movable holder 4 is transferred to shear force.

The vertical load, taking into account the forces of ground rubbing against the inner walls of the fixed casing 3, is transmitted to the movable casing 4, i.e. onto the cutting plane, then through the bearings 5, the base 6 onto the support consisting of rods 7, and fixed by strain gauges 8. Moreover, in the process of conducting soil studies, the tensors 8 measure not only the true value of the vertical load in the section plane, but also the change of this load during the cut, which is very important when studying the processes occurring in the soil during the cut
