Abstract

The invention relates to hydraulic construction. The purpose of the invention is to increase the stability of the structure. The soil structure 2 is poured in layers. The base 4 of the film diaphragm is installed vertically in the soil of the base 1 and in the upper part of the structure 2. Between sections 4, sections 3 of the diaphragm are displaced in height, width and length of the structure. Section 3 is made in the form of a container with film walls. In the vessel walls there are windows closed with an osmotic film. The cavity of the container 3 is partially filled with a concentrated solution of the substance. When creating the backwater by the water area 10, the soil of the structure is moistened. Moisture from the soil penetrates through osmotic tension through the windows in the cavities of the containers 3, fill them. The containers 3 increase in volume and create expansion forces in the ground. Between containers 3 and around them, a zone of highly compacted soil is created with extremely low filtration characteristics. 1 hp f-ly, 3 kn. with S (L

FIELD OF THE INVENTION The invention relates to hydraulic engineering.

The purpose of the invention is to increase the stability of the retaining soil structure.

Figure 1 shows a cross section of a structure with an anti-filtration diaphragm; figure 2 - section aa in figure 1; Fig. 3 is a sectional view of a membrane-impermeable diaphragm section.

The supporting soil structure consists of a ground structure 1 erected on the ground 1 with sections 3 film anti-filter diaphragm, made in the form of tanks, and vertical film sections 4. Section 3 consists of film walls 5 with windows 6 covered with an osmotic film 7 The cavity b of section 3 is partially filled with a concentrated solution of substance 9, for example, table salt.

The rest of the designations on the drawings are as follows: 10 - the water area H is propped up - water depth in the water area; a, b, c - gaps between sections 3; № 1-5 - numbers of rows of the film diaphragm section.

Retaining soil structure (erected as follows.

Crush on the ground boundaries facilities.

The ground surface 1 base is prepared. Mark the route of the laying of the vertical film section 4 and lay section 4 in the base soil 1. Delivered to the construction site of section 3 of the film

aperture. They are taken to the site.

empty packed in packs like this

for example, it is made with plastic bags. Each section 3 is provided with a neck (not shown) with a closure cap. On the object, the volume of the cavity 8 is filled through the throat with a concentrated solution of the substance. Ground the base 1 or into the groove made in the ground 1 at a distance of b from the upper edge of section 4 place section 3 of row 1 with the gap between the ends of the containers. The soil is filled with layers. Bbmie row No. 1 to its left is laid row No. 2.Rd No. 2 is placed at a distance from row No. 1, equal to b horizontally and equal to half of its height. Above number 2, half the value from the distance b on the horizon

hoists in the direction of the lower reach are placed in row No. 3 of sections 3 with a clearance in the amount between them when laying in rows. As the layers of soil are removed, they are laid out row by section 3. And so to the very top of the structure. The result is a diaphragm formed from two inclined sections 3. In the upper part of the structure, section 4 of the membrane diaphragm is placed.

The construction is supported by the water area 10. The construction 2 is saturated with moisture. The moisture spreads in the soil surrounding the sections 3, penetrates through the osmotic film 7 and through the windows 6 enters the cavity 8 of the container. The containers 8 are filled, increased in volume and create expansion forces in the ground. Osmotic pressure reaches extremely high values. This pressure is transmitted by sections 3 to the ground. The pressure on the ground is great. The soil in the spaces between the containers, around them and adjacent to the containers, is significantly compacted. Due to the presence of a backwater of H, a filtration flow is created in the body of the structure. He has to overcome a zone with extremely low filtration characteristics. This zone consists of waterproof film sections .3 and an extremely dense soil between them and around them. This achieves an increase in the stability of the retaining soil structure. Tanks can be placed not in two, but in a larger number of rows. This increases the lateral dimensions of the anti-filtration media. Noah zone.
