water through the bulkhead in the embankment.

There is a known method of preventing the formation of inoculations at the intersection of the flow of water and the embankment with the transom.

a structure, for example, an embankment of a railroad road with a culvert pipe in it, including the formation of a warming pond on the water flow path to the culvert and an insert in the embankment from the ClJ material.

A device dp is known to implement this method, including a culvert and a warming pond in front of the Cl j embankment.

The drawbacks of the device and method are the absence of a guarantee against the formation of ice on the free-flow side of the embankment, as well as the high consumption of special expensive drainage material.

There is also known a method of preventing ice formation at the intersection of a FLOW of water and an embankment with a culvert, including a device on the flow path to the embankment of a heat-insulating pond, release of water from this pond under the hood, the direction of the flow to the culvert in winter time under the protection of the thermal insulation to pass flow through the mound through the C2 culvert.

It is also known a device for carrying out a method of preventing ice formation at the intersection of a water flow and an embankment with a culvert construction, including a warming pond with a screen made with a water outlet window located below the water level in the pond, and a heat insulation coating positioned above the water flow during the period are negative to air temperatures 21.

A disadvantage of the known device and method is the low reliability of an ice-free passage of the stream through the access control structure in the embankment, since the accumulation of natural heat in the summer to pick up the heat in the winter is provided only in a warming pond.

The aim of the invention is to improve the reliability of a non-fatal flow of water through a culvert in an embankment.

This goal is achieved by the fact that, according to the method, water is released from the heat insulation rod in two streams — the main one with a low temperature and the additional one with a high temperature, while the additional stream is heated by heat accumulated in the summer period in a special heat storage container then the pepper is passed through the culvert, the construction of the main and additional streams is mixed in the water mixing tank; moreover, in summer the water in the warming pond and warmer than the storage tank STI preheated natural heat, and in winter time insulate yuschy pond heat storage tank and the mixer is coated with heat insulation.

In addition, the device is equipped with a heat storage container, located between the culvert and a heat insulation pipe, made in the form of a recess in the soil, filled with filtering heat-absorbing material in the form of a stone draft and a mixing capacity in the vice of the excavation in the ground and placed in the intersection building and in the center of the building. storage tank, and the heat storage container is connected by pipes, respectively, to the heat insulation spout and mixing capacity, the structures themselves, which insulate Prutz, and heat-accumulating capacity in the period of positive temperatures of the Syabzha region, are usually covered by a warming pond, and the heat-absorbing coating is placed above the warmth pond, and the heat source isn’t part of the area. A tepizizopen shchionny coating of the flow is made in the vice of the shells of porous concrete. FIG. 1 shows a device for the implementation of the proposed method of passing a stream in the summer, on the side; in fig. 2 - the same, in winter time, side view; in fig. 3 - the same, in the summer, Vice above. The device includes successively placed embankment 1 with a transmissive structure 2 therein, for example, a railway embankment with a reinforcement pipe, an aggregation tank 3, a heat storage container 4, a pipe with a locking device 6, connecting tanks 3 and 4, a warming pond 7 with a retaining screen 8, having a spillway window 9, a pipe 10 with shut-off devices 11 and 12, connecting tank 4 with a spruce 7, a branch pipe 13 with a shut-off fixture 14. The positions also indicate the main stream 15 of water enclosing the dams 16 of the warmth sprout 7, heat-absorbing coating 17 in the form of blackened puffed SHITS, heat insulating coating 18, in the form of a layer of porous ice, weir 19, filtering heat-absorbing material 20 in the form of a rock layer, heat-insulating coating 21 of a stream in the form of inventory shells of porous concrete, layer 22 waterproofing, an unbreakable bed 23 of the watercourse, a mixed stream of water 24, natural soil 25. The process is carried out in two stages: in summertime and in wintertime. By summer time is meant the period of the year with positive air temperatures (part of spring, summer, part of autumn), and under winter time, a period with negative air temperatures (part of autumn, winter and part of spring). In summertime, the method is performed in the following sequence. Water is collected in an insulated pond 7, the water surface of which (Fig. 1 and 3) is covered with a heat-absorbing coating 1.7, for example, in the form of blackened floating tsitov, made of high thermal conductivity mat. The heat-absorbing coating accumulates solar energy, heat is transferred to them by water. In addition, the water is also heated by atmospheric air. In this case, water separation occurs in pond 7: warmer particles of water rise to the surface of the pond, colder particles descend to the bottom of the pond. With a long-term summer exposure, the water in pond 7 warms to its full depth. Heat is given by the water to the ground 25 at the bottom of the pond 7 and is accumulated by it. With the shut-off devices 12, 14, 11 and 6 closed, water is poured from the rod 7 through the -slutine window 9 in the retaining screen 8, flows down the weir 19 and as the main flow enters the water-mixing container 3. Opener 15 and 11 the stop devices 14 and 11 Heat water from the surface of the pond 7 through the pipe 13, the free end of which is placed in close proximity to the heat absorbing coating 17, enters the pipe 10 and pours out of its end placed at the bottom of the heat storage tank 4. Water due to the difference in water levels in the pond 7The container 4 is poured into the container 4 under pressure, fills the container 4, gives off heat to the filter heat-exchanging material 20 and the soil 25 surrounding the container 4. During the warm water flowing into the container 4 it is brought and accumulated by the material 20 and soil adjacent to the container 4, huge amount of heat. In addition, a significant amount of heat is transferred to the container 4 by the heat-absorbing coating 17, laid on the surface of the container 4. The shut-off device 6 is opened. Water from the container 4 through pipe 5 is fed under pressure into the water mixing unit. bone 3 as a result of a change in water levels in tanks 4 to 3. In tank 3, the water of the main stream 15 and the water from pipe 5 are mixed and in the form of a mixed stream enters the culvert 2, drains from it on the lower side and is drained from the embankment 1 in a known manner (along the ground channel). in winter, the method is carried out in the following sequence: water is collected in a warming pond 7, whose water surface (Fig. 2) is insulated; 1m by coating 18, for example, in a vice porous piece. The knight in the stem 7 takes away from the soil 25 of the central part of the warmth, ame-filled with pet. When this happens, a spawning wave occurs:

It turns out at the tsna prutts, most likely it is at the surface of the pond. The locking device 14 is closed, the locking device 12 is opened. The water from the bottom of the pond 7 is most warm.

through the free end of the pipe 10 enters the pipe 1O, passes the locking devices 12 and 11 and pours out onto its end placed at the bottom of the capacitance 4. After filtering through the material 20, the heat is additionally heated from the bottom. Water flows into pipe 5 and flows from tank 4 to tank 3. There the heat is mixed with cold water from the main stream 15 coming from pond 7 through window 9. The mixed stream from tank 3 enters the culvert 2 and pours out of it . In order to reduce heat losses in containers 3 and 4, they are covered with a heat insulating coating, for example, in the form of a layer of a porous piece. To this end, the main stream 15 and the mixed stream are covered with a heat insulating coating, for example, in the vice inventory of porous concrete shells.

Heating of the main stream of cold water by mixing it in the tank 3 with an additional stream of warm water is provided to increase the reliability of ice-free passing through the culvert 2. The flow of warm water is regulated by using shut-off devices of auxiliary 11 and 6, the heat accumulated over the summer in the grounds of the pond 7 and in the material 20 of the container 4 and the ground mass surrounding the container 4, it is consumed during the entire winter time to heat the water flowing through the structure 2.

The use of the invention allows to increase the reliability of culverts and reduce the cost of their repair and operation.
