Abstract

FIELD OF THE INVENTION The invention relates to hydraulic engineering. The purpose of the invention is to reduce the time and money spent on the construction of a storage tank, as well as to increase the reliability of its fencing walls. On the natural ice cover 3, the ice walls, consisting of layers 7–9 of ice, are frozen along the perimeter of the boundaries of the ground stock. Along the outer boundaries of the warehouse, a slot 11 is made in the ice cover 3. The ice tank 4, limited to the ice bottom 10 and ice walls 7-9, is flooded into the water area 1 of the reservoir until the ice bottom 10 on the ground 2 bottom of the reservoir.

The invention relates to hydraulic construction and is intended to improve the reliability of the walls of the fencing of an underground warehouse in a reservoir.

The purpose of the invention is to reduce the time and money spent on the construction of a storage tank, as well as to increase the reliability of its fencing walls.

Figure 1 shows a part of a reservoir with a natural ice cover and the boundaries of the storage tank, section; Fig. 2 shows the same, with the frozen inner layer of the ice walls of the tank, a section; fig. 3 - the same, with a second layer of ice filled with a frozen wall, a section; 4 is the same, with a frozen outer layer of the ice walls of the vessel and with a slot in the ice cover near the vessel walls, a section; figure 5 - ice on the capacity of the groundwater warehouse, lowered into the water area of the reservoir on the part of its depth, section; Fig 6 - ice on the tank installed at the bottom of the reservoir, section; 7 - the same, view in plan; Fig. 8 shows the capacity of a warehouse filled with soil, a section; Fig. 9 shows the container wall during the period of its freezing, section.

In FIGS. 1-9, the following notation is taken: water area 1 of the reservoir, bottom 2 of the water reservoir, natural ice cover 3 in the reservoir, capacity 4 soil storage, boundaries of storage 5, wall 6 of the storage fence, layers 7-9 of the ice wall of the storage , ice bottom 10 of the storage tank, slot 11 in the natural ice cover, stored soil 12, layers 13 of the stored soil, support heels 14-17 in the ice wall, film walls 18-21, layer 22 of water in the interfilm space, layers 23 and 24 frozen ice in the interfilm space.

The method is carried out as follows.

After the formation of a natural ice cover 3 in the water area 1 of the reservoir, it is marked on the ice cover of the boundary 5 of the capacity of the soil storage (Fig. 1). The ice walls 6 of the storage fences on the natural ice cover within the boundaries of the storage tank are frozen over, the walls 6 are covered with layers 7–9. To do this, 3 borders of the layers 7–9 are marked on the ice cover 3. Burrs are drilled in ice, bearing piles 14-17 are inserted into them (Fig. 9). Film panels are pulled on the cages so that film walls 18-21 are formed. As a result, a three-layer division of the wall 6 is formed. The number of ice layers can be any depending on the wall thickness 6. The height of the layers is different: the inner 7 is the smallest height, the outer 9 is the greatest height exceeding

the size of the depth of water 1 pond. The interfilm space of the inner layer 7 of the wall is filled with a layer of water, it is frozen to form a layer 23 of ice. The thickness of the layers 7-9 take into account the strength of the film walls 18-21. The height of the layer 22 of water poured into the interfilm space is also determined from ensuring the strength of the film walls 18-21.

0 On a layer of ice 23, a layer of water is poured, frozen and a layer 24 is obtained. As a result, an inner layer 7 of the wall is obtained. Since the film is thin and heat-conducting, the freezing of layers 23 and 24 occurs quickly.

Then pour water into the interfilm space of the wall layer 8. Flooded water layer 22 quickly freezes as it borders on the ice wall of layer 7 and is cooled

0 atmosphere film 20. A layer of water 22 is poured around the perimeter of the warehouse and get a layer of ice around the perimeter of the tank 4 of the warehouse. Gradually freeze the wall layer 8 (Fig. 3), and after it, the bay afterwards, layers of water freeze the ice wall layer 9 (Figure 4). A slot 11 is made in the natural ice cover 3 around the walls b of the tank 4 of the warehouse (figure 4).

Start the immersion of the tank 4,

0 consisting of ice walls 6, frozen to the ice bottom 10. After the formation of the slots 11, the tank 4 is immersed by its own weight at a certain depth h in the water area of the reservoir (Fig. 5). Po5 barely reduces the buoyancy of the tank 4 by pouring water into it. The easiest way is to drill holes in the ice bottom 10, for example, with an ice drill for a fisherman. The holes are not drilled over the entire thickness of the ice of the bottom 10. The holes are placed evenly over the bottom area 10. Then the bottom is punched at all of the holes at once. Through these holes, the tank A is filled with water from the water area 1. The tank 4 is lowered to the bottom 2

5 reservoir (6). Capacity 4 of the warehouse is ready to be filled with soil (6, 7).

Start to fill the tank with 4 soil. The soil is poured into the container by 4 inclined layers 13, starting from the walls 6 of the warehouse. The tank is filled with 4 soil over the entire height of the walls 6, around the entire perimeter of the warehouse. Layers 13 of the soil (Fig.8) have in the direction from the walls of the warehouse to its middle. Priming

5 12 it is advisable to lay them above the walls 6 so that as ice melts in the layers 9, 8 and 7 of the wall, the free interfilm space is filled with breaking around soil. A soil mass lined

outside multi-layer film coating.

Claims (2)

Claim 1. Method of storing soil in a reservoir, including erecting a storage tank fence and filling the tank with soil, while constructing a fence, natural ice cover is formed in the pond, breaking up the warehouse boundaries on the ice cover, freezing on the ice cover the boundaries of the warehouse of the walls of the fence of the warehouse, making along the perimeter of the container of the warehouse slots in the natural ice cover of the reservoir and the flooding of the container of the warehouse with an ice bottom, which differs from reducing the time and cost of building a storage tank, as well as increasing the reliability of the walls of its fencing, freezing the walls of the storage tank on the ice cover, is performed with several layers of ice along the TOPSCHINR wall with different layer heights, freezing takes place alternately the layer of the smallest height and ending with the highest outer layer, with each layer freezing1 along the entire perimeter of the warehouse, the layers also produce filling of the container with soil to the entire height of the walls of the container around the perimeter of the warehouse, The soil scaffolds are inclined in the direction from the warehouse walls to its middle. 2. The method according to claim 1, characterized in that the walls of the ice storage capacity of the warehouse are made of several rows of film walls that pull onto the supporting packs frozen into the ice, arranged in rows, between the rows, -: , different thickness of the ice layer of the wall, and then fill the interfilm space with water with its freezing. 2 phyaz four J 7Ж / 7 //// Ж ЖЖ ЖЖ ЖЖЖЖ Ж Gjtfp R h .4j hp e TTT GI xb BUT 69t / l69l al 17, 2 V v 7 th that : 19 & 13 ///
