Description

one

The invention relates to devices for studying stresses in the ground, in particular, for determining the vertical normal and tangential stresses over the entire length of the bulk of the bulk granulated soil in the laboratory.

Devices are known for investigating the deposits in rpyiiTOBoii water, including a bed and an platform consisting of sections, each of which is mounted on a support with the possibility of horizontal movement in the horizontal direction.

The purpose of the invention is to provide the possibility of simultaneous determination of the vertical and normal tangent stresses along the entire length of the sole of the filled synthetic soil.

This is achieved by the fact that each of the sections of the device is iodine to the rocker arms, a balanced vessel with liquid, the flow of which is regulated by an electromagnetic valve, each of the rocker arms is made with upright meters mounted with the possibility of interaction with the electromagnetic valve. The rocker can be mounted on a compliant support, made in the form of a compression spring with a support rod connected to the bed frame by means of vertical movement restraints, for example, bolts.

The drawing shows the proposed device, a General view.

The device for studying stresses in the ground environment includes a frame with beam J and columns 2, a platform consisting of sections 3, mounted on suspensions 4, “Armature 5 with support 6 and balancing vessel 7 with liquid, the flow of which is regulated by the solenoid valve 6 and mounting pipe 9, cantilever strips 10 interacting with the sensor holders 11, spring 12, szhagi supporting rod 13 suspended from the beam by means of bolts 14.

The device works in the following ways. A group model is placed on the platformer according to the experience of the profile. In this case, the stop 6 of the yoke supports the electric circuit of the electromagnetic valve 6 and through the pipe 9 the water enters the vessel 7 until the weight of the water in the vessel 7 balances section 3 of the platform.

A stop 6 opens the motor and the flow of water into the vessel 7 is stopped.

Take readings on the gauges of blood vessels. The sum of the counts in two vessels,) equilibrating one platform section, referred to the area of this section, is the average value of the vertical; normal stress in the section under study (along the section axis).
