The invention relates to the field of linear construction of hydraulic structures and transport facilities, in particular to the construction of piers on the coast of the Northern seas, has to do with power using natural energy sources, wind, air quality, ecology, environment and can be used in the construction of sea and river berths, jetties and dams in the offshore waters of the Arctic seas and in the lower reaches of the Northern rivers for the construction of roads, passages in the waters of the lakes, runways, and other linear facilities in flood-prone and wetland areas of the subarctic and Arctic areas of Russia, and during the construction of piers in Antarctica.

The famous pier on the coast of the Northern seas, including hydraulic structure of reinforced concrete and steel structural elements (...) (RD 31.55-93 and others, see folder "Different" about ice...).

The disadvantages of the known reinforced concrete and steel piers on the coast of the Northern seas are relatively high complexity and cost of their erection in severe climatic conditions or the complexity of large and medium vessels with cargo for the production of construction works close to the shore, to the place of unloading due to the small depth of water, big time vozvedenie complexity of building such waterworks.

The disadvantages of the known ice of the temporary piers are their fragility, lack of reliability, a relatively small linear dimensions, which does not allow to achieve their depths necessary to approach heavy draft vessels, as well as the underdevelopment of ice construction, which limits the durability and functionality of the piers reduces their attractiveness to investors.

The purpose of the invention is to create long-term ice platform for the construction of a line of fortifications on the coast of the Northern seas of Russia, increase strength, stability, reliability, durability and functionality, increase (as a result of implementation of the invention) transport accessibility of small settlements and work places in the North, to accelerate the development of the Northern regions of Russia, to improve the environmental, economic efficiency and investment attractiveness of the construction of the ice structures to support social and economic needs of the population.

This goal is achieved by the fact that the pier is made in the form installed on the seabed ice platform of rectangular cross-section, are mainly located at the mouth of the Northern navigable rivers, equipped located on the banks metrosexuality power tower type, W is dostoy cooling system and air cooling system in the form of shafts, hydrothermolysis screen placed on the surface of the platform, and solid flooring in the form of a flat rectangular elements in terms of shape, arranged at an angle of 45 to the longitudinal axis of the platform. While the platform is designed with slopes on both sides, located at the level of the floating ice, and provided with reinforcing mesh placed at the level of the median plane of the air channels. Liquid cooling system is made of inter-connected batteries atmospheric cold, pipelines, cooling and consumers of refrigerant and piping cooling placed along slopes and under teplogeneriruyuschim the screen.

The invention is illustrated by drawings, where Fig.1 in plan, Fig.2, 3 - sections shown pier, Fig.4 - the plan shows a portion of the pier, and Fig.5 and 6 in plan and section showing the battery naturally cold.

The design of the pier consists of ice array 1 includes an air tunnel 2, the batteries of atmospheric cold 3 and 4 (4 banks), piping refrigeration 5, 6, teplogeneriruyuschie screen 7, the road surface 8 and the consumer of liquid refrigerant 9.

The piers on the coast of the Northern seas of Russia place mainly at the mouths of navigable rivers, because in the absence of roads and Railways rivers are practically the only the military transport system for a large number of goods from the southern regions of the country.

Before construction of the pier near on an elevated stretch of coastline establish one or two microsoftie tower power plant 10, the electric power which is necessary both during construction and during operation of the pier. Energorashodyi tower, if necessary, equipped with coastal navigation, lighting and other necessary equipment.

Before the onset of winter produce, alignment strip of bottom - Lodge, the Foundation of the future of the pier. With the onset of sustained negative air temperatures and education on water ice cover 11 along the contour of the future pier perform end-to-end slots, install non-removable formwork and produce a layer-by-layer freezing ice. In the process of forming ice array 1 are laid pipelines cooling 5, 6. On the sides of the ice massif perform with slopes of 12 to an angle of 30-40 to the surface of the ice cover 11. As numerazione ice ice array 1 under its own weight falls on the prepared bed of the sea / river bed, which gets frozen ice due to the low temperature of the ice array.

The entire length of the ice masses have not less than two air tunnels 2. The 2 tunnels, which are designed primarily for cooling ice masses in the warm period of the year, have a 1.5-2.0 metres from the slight pressure from the beginning of the faces of the walls of the pier and combined with the atmosphere of supply and exhaust ventilation pipes 13.

On the surface of the ice masses and the coast, install the batteries naturally cold (Oh) 3, 4 in the insulating sheath 14. Ah 3 connects through piping cooling 5, 6 with a circulating pump 15, a battery of cold 4 role of expendable tank, and consumer refrigerant (fuel) 9. As a coolant in liquid cooling systems using Arctic diesel fuel, consumers are road, track transport and located at the pier of the court. All batteries cold equip with a built-in shell tanks thermosyphons seasonal activity 16. Each battery is cold, in which is placed holdorova 17 and coil air pipe 18, connected respectively with the refrigerating machine 19 and the compressor 20. On the surface ice of the array 1 is placed teplogeneriruyuschie screen 7, and on top - solid surface 8 of the concrete slabs. Flat solid cover feature in the plan relative to the longitudinal axis of the pier at a 45 angle and welded to each other through embedded parts. The gaps between the slabs of concrete fill.

Construction of linear facilities, including piers on ice performance, on the coast of the Northern seas in countries such as Russia, USA (Alaska) and Denmark (Greenland), it becomes possible, pascalc the average annual air temperature - negative, and the preservation of ice array 1 in the summer season in totominskom condition is ensured by the air and liquid cooling systems that operate on a stand-alone sources of natural energy.

In the cold period of the year the tunnel 2 is used as a cooling space. Frosty with low temperature air is supplied and discharged into atmosphere through the vent pipe 13. Increase the cooling effect and the strength of the ice in the peripheral layers of ice masses is achieved through close to the vertical walls of one -, two -, or multi-tiered layout of tunnels 2. During operation of the pier tunnels 2 is also used as a refrigerator for a long time (backup) storage products. In summer (July - August - September) for cooling the air in the tunnels use the compressor 20, the electric power which is served from versamatic power plants 10.

Cooling system with liquid refrigerant, operates as follows. In the cold season, the refrigerant in the Ah is cooled using thermosyphons seasonal 16, where the non-freezing fuel circulates through the temperature difference between the ambient air and the refrigerant (fuel). The constant cooling of the refrigerant to a low temperature leads to incandescent cold in Ah. At the end of the winter temperature is RA refrigerant in the tank can reach minus (35-40C). At higher temperatures, for example, to minus 34C thermosyphons seasonal 16 is automatically "locked", that is, they circulation of fuel stops. In a liquid cooling system, there is a continuous selection of refrigerant fuel from a supply tank (Ah-4) motor vehicles or watercraft. This causes the natural-artificial circulation of fuel through pipelines cooling 5, 6, lowering the temperature and, consequently, the increase in strength properties of ice.

The amount of fuel taken from the system by consumers, reimburse the fuel that enters the Ah-4 to the pipe 21 from the supply tank.

In the summer season includes a pump 15, through which the cooling system carry out the circulation of the liquid refrigerant with low temperature. When the temperature of the refrigerant to minus 10C) in the automatic mode of the refrigeration machine is 19 and works to restore the estimated negative temperature of the refrigerant in the cold storage and cold 3, 4.

In the summer season when there are currents in the area of the pier, ice come in motion. Ice meets on his way pier, begin to climb the sloping surface of the slope 12 and under its own weight break. The presence of slopes can reduce the horizontal pressure LDO is on the pier, to ensure the sustainability of ice structures and, as a result, to reduce the transverse size of the pier.

Length of sea pier in shallow shelf waters of the Northern seas can reach several hundreds and even thousands of meters, width - not less than 15 meters. While Pearce performs its basic functions berthing and handling facilities. Under certain conditions and circumstances pier can perform the role of a runway.

Concrete slabs that make up a hard coating 8, stack on teplogeneriruyuschie screen 7 at an angle of 45to its base. This arrangement of the plates is selected to reduce the shock load on the transport when moving wheels through the joints of the plates and, on the contrary, the load from the wheels of the vehicle on the joint plates. The angle of 45With appointed from traditional manufacturing slabs of a rectangular shape, as the most rational from the point of view of their manufacturing transportation and warehousing. Theoretically and experimentally, that the impact load on transport and transport on the plate decreases exponentially with decreasing slope of the line of intersection of the trajectory of the wheels.

Pearce, representing placed on the coast of the Arctic seas linear gravitational hydraulic structure, the ex is different, however, that pier is made in the form installed on the seabed ice platform of rectangular cross-section, are mainly located at the mouth of the navigable rivers, equipped located on the banks metrosexuality power stations of the turret type, a liquid cooling system and air cooling system in the form of shafts, teplogeneriruyuschim screen placed on the surface of the platform, and solid flooring in the form of flat elements rectangular in plan form, arranged at an angle of 45to the longitudinal axis of the platform, while the platform is designed with slopes on both sides, located at the level of floating ice, liquid cooling system is made of inter-connected batteries atmospheric cold, pipelines, cooling and consumers refrigerant and piping cooling placed along slopes and under hydrothermolysis the screen.

SUBSTANCE: method for protection against wave action of a single hydraulic structure consists in the fact that arriving waves of the hydraulic structure are separated on both sides around the structure by creating horizontal near-surface streams diverging to both sides across the direction of waves, which are formed by a flat symmetrical floating-up gas-liquid flow that is created in water environment under arriving waves. Symmetry plane is located in a diametrical plane of the structure and perpendicular to wave movement. Flow rate of gas, mainly air is chosen so that horizontal velocity of near-surface streams of a gas-liquid flow is at least 0.2 of velocity of arriving waves. A zone where a gas-liquid flow is formed is located in the above symmetry plane at the distance before the hydraulic structure of not closer than (0.3-0.5) of the width and not farther than (1.5-2.0) of the length of the hydraulic structure. Length means the structure size along diametrical plane in the wave direction, and width means the size along the wave front. Gas-liquid flow is created at the depth of not less than 0.6 of amplitude of an arriving wave by supplying the air under pressure to water environment so that bubbles are formed. A device for the method's implementation includes a discharge device on both sides around the hydraulic structure of arriving waves based on the use of a gaseous substance, mainly air. The above device is made in the form of a deaerator of water environment with bubble air inclusions, which consists of perforated tube 1 located along the diametrical plane of the structure along the movement direction of arriving waves and increased air pressure source 3 connected to it via main line 2.
