The invention relates to the construction, in particular to the structures of foundations of structures erected in difficult ground conditions, when uneven precipitations or lifting of the base are possible.

The aim of the invention is to increase the reliability and effectiveness of protection.

The pa of FIG. 1 shows a device for protecting the structure against deformation of the precipitation;

The device for protecting structures from base deformation includes a foundation body 1 with cavity 2, filled with swelling-shrinkable material 3, for example clay, on which piston 4 is supported, which serves as a support for the structure itself, installed with a gap 5 relative to the cavity walls, and fixture 6, which controls flow fluid 7 to the base 2 iolost 2, depending on the height position of the foundation 1 and the piston 4. The fixture 6, which controls the flow of fluid 7, can be made in the form of communicating vessels 8 and 9, one of which (8) - for} 1 with piston 4, and in the other (9) constant fluid level 7 is maintained.

The device for protecting the structure from the deformation of the bases works as follows.

the least swelling of the soil does not occur.

In the case of lifting the base, all the equipment rises and liquid cannot enter the basement cavity. As a result of natural steam through the gap 5, the moisture content of the filling material decreases, it shrinks and the piston and the weapon are lowered. The process of shrinking continues until the level of the drain opening 10 of the vessel 8 dies to level the liquid in the vessel 9

By placing the vessel 9 in such a way that the level of the liquid in it is constant, a stable altitude position of the entire structure is provided. If this is not required, the vessel 9 can be placed on the above-ground structures of the structure, as a result of which only uneven deformations of the base are compensated.

Claims (1)

Invention Formula 1, A device for protecting structures against base deformation, including a foundation with a cavity, inside which is placed a filling material and a piston supported by a filling material, characterized in that, in order to increase reliability and effectiveness of protection, shrinkable primer In the case of base deformation, 35 is installed with a gap relative to the least swelling of the soil does not occur. In the case of lifting the base, the whole device rises and liquid cannot enter the cavity of the foundation. As a result of natural evaporation through the gap 5, the moisture content of the filling material decreases, it shrinks and the piston and the structure are lowered. The shrinking process continues until the level of the drain opening 10 of the vessel 8 reaches the level of the liquid in the vessel 9. By placing the vessel 9 in such a way that the liquid level in it is constant, a stable altitude position of the entire structure is ensured. If this is not required, the vessel 9 can be placed on the above-ground structures of the structure, as a result of which only uneven deformations of the base are compensated. Invention Formula 1, A device for protecting structures from base deformation, including a foundation with a cavity inside which a filling material is placed, and a piston supported by a filling material, characterized in that, in order to increase the reliability and effectiveness of protection, a filling material is used as a filling material. shrinkage primer installed with a gap relative to an example of its settlement, the base body 1 together with the piston 4 moves downwards. At the same time, the level of the drain opening 10 of the vessel 8 becomes lower than the level of the liquid in the vessel 9 and it enters the cavity 2 of the foundation 1. The soaked filling material 3 swells and raises the piston 4, and with it the structure. After reaching a ratio of 4 and vessel 8 of the initial position, the flow of fluid into the cavity of the foundation stops and the walls of the cavity, and it is equipped with a device that regulates the flow of fluid into the cavity of the foundation, depending on the height position of the foundation and the piston, 2, the apparatus according to claim 1, wherein the device regulating the flow of fluid is made in the form of communicating vessels, one of which is connected to the piston, and the other is maintained at a constant level of liquid.
