Description

The utility model relates to devices for modeling soil moisture processes and is intended to study the dynamics of soil moisture in depth in laboratory conditions.

From the existing prior art, the INSTALLATION is designed to determine the filtration capacity of the soil, including a pipe section with a hole in which a soil sample is placed, an elastic membrane that does not allow water to pass through the pipe section, which has a hole matching the hole in the pipe section, to a drainage hose is connected to it so that its junction with the elastic shell is tight, and in the elastic shell above the level of the drainage hose there is a drainage material covered with a lower filter from zero resistance, on which a soil sample is placed, covered by an upper filter with zero resistance, to which a water supply hose is connected, and the joint of the water supply hose with an elastic sheath is sealed with at least one rubber cuff; an expansion tank is connected to the water supply hose, and the drainage hose is located above the vessel mounted on the electronic balance; to change the stress-strain state of the soil sample, the installation has a piston and a loading rod (RU 93151, IPC G01N 15/08, U1, publ. 04/20/2010).

The claimed technical solution is aimed at improving the patent for utility model RU No. 147593 dated 07/08/2014. "DEVICE FOR CONTROL OF MOISTURE SOIL", the patent holder of which is the Omsk State Technical University Federal State Budgetary Educational Institution of Higher Professional Education, the installation contains n-sections with holes in which the soil is located. Sections form a rectangular case divided by partitions. The front wall of the sections of the casing is made of a transparent material, such as polycarbonate or glass, for visual control of soil moisture, and other walls of the casing can be made of a hydrophobic material, such as plastic or textolite. On the opposite front-back wall of each section, in its central part, holes d are made for sampling soil for subsequent monitoring of soil moisture in accordance with GOST 5180-84 “Soils. Laboratory methods for determining physical characteristics. " Each hole d is plugged with a plug. On the upper part of the casing of each section there is a lid made of the same material as the casing itself and designed to prevent the evaporation of water. The utility model allows in laboratory conditions to provide the ability to control in time and in depth the process of moistening the soil, depending on its composition.

The main disadvantages are: difficulty in extracting soil after laboratory testing.

The task to which the proposed technical solution is directed is the ability to extract soil after laboratory testing.

This technical result is achieved by the fact that in the device for controlling soil moisture [patent RU No. 147593 of July 08, 2014], consisting of n-sections, in each of which holes d are made, n-sections together form a rectangular housing divided by partitions on the section, the front wall of the sections of the body is made of transparent material, and the holes d are made on the opposite front - back wall of each section, in its central part, in addition, on the upper part of the body of each section there is a lid, as stated The technical solution in the lower part of each section was equipped with “unloading hatches”, which made it possible to freely remove “wet” soil from the sections after laboratory tests.

In FIG. A device for controlling soil moisture is presented.

A device for monitoring soil moisture, consisting of n-sections with holes, in our case 5 (five), in which the soil is located, form a rectangular housing 1, divided by partitions into sections. The front wall of the sections of the casing 2 is made of a transparent material, such as polycarbonate or glass, for visual control of soil moisture 3, and other walls of the casing can be made of a hydrophobic material, such as plastic or textolite. On the upper part of the casing of each section there is a lid 4 made of the same material as the casing itself and designed to prevent the evaporation of water. In the lower part of the casing of each of the sections, “unloading hatches” 5 are made, which make it possible to freely remove “wet” soil from the sections after laboratory tests.

Consider the work of the stand.

A soil sample 3 of a given mass is poured into any section of the housing 1 of the device for controlling soil moisture (the mass is determined depending on the volume of the section). The amount of water calculated depending on the mass and the initial moisture content of the soil sample 3 is poured into the section from above and hermetically closed with a lid 4 to reduce moisture loss through evaporation during the laboratory study, and at the same time, the start time of the laboratory tests is fixed. At regular intervals, every 30 minutes, through the front transparent wall 2, soil moisture is visually monitored, “unloading hatches” 5 are made in the lower part of each section, allowing unhindered removal of “wet” soil from the sections after laboratory tests.

The proposed technical solution allows in laboratory conditions to freely remove “wet soil” from sections after laboratory tests, through “discharge hatches” made in the lower part of the sections.

Claims (1)

A device for controlling soil moisture, consisting of n-sections, in each of which holes d are made, n-sections together form a rectangular case divided by partitions into sections, the front wall of the sections of the body is made of transparent material, and the holes d are made on the opposite front - the back wall of each section, in its central part, in addition, on the upper part of the body of each section there is a lid, characterized in that “unloading hatches” are made in the lower part of each section, allowing esprepyatstvenno delete "wet" primer of the sections after laboratory testing.
