Product Device

The working chamber consists of a platform 15, a base 2 and a cylinder 19 (see figure 1).

The pneumatic cylinder 19 with the help of nuts is fixed on four studs of the platform.

The transparent cylinder of the working chamber is installed on the base 2.

A platform 15 with a fixed pneumatic cylinder 19 is mounted on the upper part of the cylinder.

The camera is attached to the base with four retractable bolts and fixed with nuts. Bolts are inserted into the grooves of the base of the working chamber.

The tightness of the working chamber is ensured by the sealing rings 23.

A soil sample is installed inside the working chamber on the lower stamp 4 between the measuring brackets.

To ensure alignment of the vertical load axis of symmetry of the soil sample, the upper stamp 8 is mounted on a folding platform, which in turn is pivotally mounted on the rack 23 and is fixed on the second rack after turning to its original position. The vertical load is transmitted through the force sensor 12 and the lower rod 11 to the upper stamp 8. The vertical movement of the stamp is regulated by a screw.

To control the safe pressure in the working chamber, a relief valve with a pressure rating of 0.6 MPa is used.

In the device of this design, it is possible to test soil samples with a different ratio between the height H and the diameter of the soil sample D. Figure 1 shows a variant with a diameter of the upper and lower stamp D = 35 mm If it is necessary to test samples of soil with a larger diameter, for example 50 mm, then other upper and lower dies with a diameter of 50 mm are used. In this case, a larger diameter stamp is worn on the lower stamp, and the upper stamp is replaced with a new one.

The lower stamp 4 with a diameter of 50 mm is part of the base 2 (see figure 1). The upper stamp 8 with a diameter of 38 mm is mounted and fixed with a screw on it. A stamp of the appropriate size is used depending on the size of the test soil sample.

Measuring brackets are mounted on two racks located inside the working chamber.

Racks 26 also serve to secure the platform (see figures 1 and 2), which is designed to install the upper rod.

On the right side of the casing, the products are located (see figure 5):

- “UPPER DRAINAGE”, “LOWER DRAINAGE” and “CAMERA PRESSURE RESET” taps 73;

- handle for carrying the product 74.

UPPER DRAINAGE and LOWER DRAINAGE taps are designed to control fluid filtration in a sample (see Figures 2 and 4) and relieve pore pressure of a soil sample. The “LOWER DRAINAGE” valve blocks the filtration of fluid from a channel connected to the bottom of the sample. The EXTERNAL DRAINAGE tap blocks the filtration of fluid from a channel connected to the upper part of the sample.

CAMERA PRESSURE RELIEF Crane is designed to relieve pressure in the working chamber.

On the back side of the base are (see Fig.6):

- connector "DS" 75 for connecting a force sensor;

The sensors that are part of the device are the primary measuring transducers of the measuring channels of the IVIS "ASIS".

To measure the vertical deformation of the soil sample, a linear displacement sensor DLP-24 35 is used, which is a component of the measuring channel of vertical deformation of the soil sample of the “ASIS” IVK.

The linear displacement sensor DLP-24 35 is mounted on a rack inside the working chamber with a nut. The sensor rod is spring-loaded and abuts against the lever of the upper stamp (see figure 1).

To measure the radial deformation in the middle part of the soil sample, a linear displacement sensor DLP-6 27 is used, which is a component of the measuring channel of radial deformation of the soil sample IVK "ASIS".

The linear displacement sensor DLP-6 27 is located inside the working chamber, inserted into the clamp mounted on the measuring bracket, and secured with a screw (see figures 1 and 2).

To measure the vertical (normal) load, the LPX 500 12 force sensor is used, which is a component of the measuring channel of the vertical load on the soil sample of the “ASIS” IVK.

To ensure tightness in the working chamber between the stem and the sleeve installed cuff 13.

The stem 40 of the sensor is spring loaded. Spring 39 serves to return the sensor to its starting position after unloading the device.

To measure the all-round pressure on the soil sample, a pressure sensor 29 is used, which is a component of the measuring all-round pressure on the soil sample of the "ASIS" IVK.

A pressure sensor for measuring comprehensive pressure is located inside the casing of the product (see figure 2, 3).

To measure the pore pressure of the soil sample, a pressure sensor 29 is used, which is a component of the measuring channel of the pore pressure of the soil sample of the IVIS "ASIS".

A pressure sensor for measuring pore pressure is installed in the base of the working chamber inside the casing of the product and is connected to a channel for filtering liquid in the lower part of the sample (see Fig. 2, 3).

Product Operation

At the command of the PC, a signal is sent to the blocks of pneumatic valves from the electronic conversion equipment through the cable. The supply valves of the blocks go into the open state and air from the pneumatic network enters the load device and the working chamber.

The pressure generated in the working chamber comprehensively compresses the soil sample and is measured using a pressure sensor.

Under the influence of all-round pressure, the sample is deformed in the vertical and radial directions. Vertical strains are measured using a linear displacement sensor DLP-24, radial strains are measured using a linear displacement sensor DLP-6.

The air pressure at the top of the pneumatic cylinder of the load device creates a vertical force, which is measured using a force sensor LPX 500.

The force from the force sensor is transmitted to the upper stamp and then to the sample.

Under the influence of vertical force, deformation of the soil sample occurs in the vertical and radial direction. Vertical strains are measured using a linear displacement transducer DLP-24, and radial strains are measured using a linear displacement transducer DLP-6.
