Description

 The invention relates to the field of construction of sports facilities, in particular to the construction of the bobsleigh track with artificial freezing of the ice cover.

 Artificial ice-covered tracks containing a gutter of a given configuration mounted on the basis of the gutter, a launching ramp and a refrigeration unit for consecutive bobsleigh and luge rides are known in the art.

 A well-known bobsleigh track for downhill running, made of separate flexible linear prestressed reinforced cement elements installed with a gap in which pipes for the circulation of the refrigerant and the intermediate bonding layer are made of cast concrete, and in some cases from wet sand, which reduces the cost and the complexity of the construction of the route, abandoning the large volume of concrete work and transfer the production of elements of the route to the factory conditions (SU, copyright certificate 744101, E 04 N 3/14, 09 .02.78).

 Known toboggan track with artificial ice cover "Sankodrom" (SU, copyright certificate 657829, 10.11.76, A 63 C 19/10), containing a gutter mounted on the base, a launching platform and a refrigeration unit, where the base and gutter are made sectional and separate sections have the ability to move across the track, thereby providing different configurations of the gutter, to provide ice coverage, each gutter section has refrigerant pipes connected to the refrigeration unit. The design of the track makes it possible to change the configuration of the track, for example, increasing or decreasing its complexity depending on the level of competition or the qualifications of athletes.

 Other various improvements to the single bobsleigh track are known.

 So, there is a known method and device for covering the track from precipitation, including flexible waterproof material placed on the surface of the structure (RU, application 94033085, A 63 C 19/12, 09.09.94).

 Another known route is additionally equipped with a thermal hydro-sun-reflecting screen placed not on the outer surface of the gutter, a transparent rigid upper overlap and a bright bright red color light channel that serves to illuminate the inner surface of the gutter and at the same time is the axis of the trajectory for moving sleds (RU, application 94025056, A 63 From 19/10, 07/04/94).

 Attraction designs are known that make it possible to track the location of moving objects, in particular, a device containing a vehicle in the form of a capsule moving along rectilinear and curvilinear sections of the path where sensors are installed that fix the location of the capsule during its movement, as well as a control unit that processes the received information ( JP, Application 2-15230, A 63 G 21/04, 08.17.82).

 Known installation for games and sports containing a guide for rolling ("Sport and game installation comprising a ridable ramp". International application WO 80/00221, 10.07.79, A 63 G 21/04). The installation is a track of a free configuration located on the ground and including two curved parallel guides assembled from separate sections, designed for rolling on roller carts-saddles. The presence of two parallel guides makes it possible for two riders to compete with each other, but this design is not intended and cannot be used for bobsledding.

 The closest solution to the proposed design is a bobsleigh track with artificial ice cover, containing an extended profile gutter mounted on a foundation foundation, the bottom and sides of which form configuration sections of varying complexity, in which, to maintain a constant minus temperature of the ice cover, regardless of climatic conditions and it is proposed to carry out a temperature difference with a gutter of the route with an external enclosing structure, where the ventilation duct for Aci air with negative temperature, which covers the supporting structure of the refrigerant (RU, patent 2029586, A 63 C 19/10, 04.05.91). However, the presence of one trench eliminates the simultaneous races of two crews, which deprives the competition of the elements of the race.

 An object of the invention is to create a route for competitions between two crews of sleds (beans) so that during the competition each crew can track the movement of the other crew and regulate their actions depending on the position in their gutter.

 The problem is achieved in that the bobsleigh track with artificial ice cover, containing an extended profile gutter mounted on a foundation foundation, the bottom and sides of which form configuration sections of varying complexity, docked on one side with a launching ramp having a straight ramp up, and on the other going to the finish line; a refrigeration unit connected to refrigerant pipes mounted in the body of the gutter is additionally equipped with a second gutter installed on a foundation base, the length of which, measured along the axis, corresponds to the length of the first gutter, and the profile along the entire route sequentially repeats the configurations of sections of varying complexity of the first gutter; at the same time, the gutters have the same number of configuration sections of varying complexity, some of which may have a mirror image of a section adequate in complexity; at the same time, on the launching platform, in the immediate vicinity of the first one, there is a parallel and equal in length to the first second straight linear accelerating section, joined with the second trough, passing into the second finishing line, each of which is an extension of only one trough, and pipes for the refrigerant of the second trough connected to the refrigeration unit, which is common to the entire track; at the same time, the track is equipped with an information system containing stationary sensors discretely fixed along the entire length of each gutter, which record the passage of the sled (bean), and light indicators associated with the sensors.

 The proposed track design will create a sports bobsleigh complex with two gutters, the length and configuration of each of which complies with international regulations, which will allow for fundamentally new types of competitions - parallel races, which, in turn, should significantly increase the entertainment of sports events. In addition, the presence of two gutters will allow competitions to be held in accordance with current international regulations, using one or the other gutter for the next races. This circumstance significantly reduces the technological breaks between races and maintains the pace of competition for each type. The work of the information system is also slightly changing, now it is intended not only to transfer the performance of the race to the general scoreboard, but also will allow competing crews to track the position of the enemy. These circumstances should be considered the main distinguishing feature and the main potential advantage of the invention.

The essential features of the claimed invention are:
- the presence of a second gutter, the length of which, measured along the axis, corresponds to the length of the first gutter, and the profile along the entire path sequentially repeats the configuration of sections of varying complexity of the first gutter;
- the presence of a second parallel and equal in length to the first rectilinear accelerating section connected to the second trough;
- the presence of a second finish line connected to the second trough;
- the presence of an information system containing stationary sensors discretely fixed along the entire length of each trough;
- the presence of a pipe system for the refrigerant of the second trough, connected to a common refrigeration unit for the two troughs.

 The design of the proposed dual bobsleigh track is illustrated by drawings.

 In FIG. 1 shows a general view of the construction of the bobsleigh track.

 In FIG. 2 shows a cross section of any of the grooves of FIG. 1.

 In FIG. Figures 3 and 4 show the profiles of tracks of various configurations (two teams of athletes are conventionally marked with Roman numerals).

 In FIG. 5 shows the connection diagram of pipelines with a refrigeration unit.

 In FIG. 6 shows a single-row placement of stationary sensors and light indicators.

 In FIG. 7 shows a two-row placement of stationary sensors and light indicators.

 In FIG. Figure 8 shows a general view of an electronic scoreboard showing the movement of athletes along two gutters.

 An artificial ice-covered sled-bobsleigh track includes two gutters that are identical in length and number of sections of the track with different complexity factors (turns, slopes, etc.) and contains an extended profile gutter 2 mounted on a foundation foundation 1 (Fig. 1) , the bottom 3 and sides 4 of which form sections 5 of various configurations (Fig. 1-4). Profile gutter 2 is docked on one side 6 with the launching ramp 7, which has a straight acceleration section 8, and on the other hand 9 - goes to the finish area 10.

 The route includes a refrigeration unit 11 (FIG. 5) connected to refrigerant pipes 12 mounted in the body of the trough 2 (FIG. 2), the refrigerant pipes 12 of the second trough being connected to the refrigeration unit 11, which is common to the entire route.

 On the foundation foundation 1 there is installed a second groove 13 similar in design to the first groove 2, the length of which, measured along the axis of the groove 13, corresponds to the length of the first groove 2, while the grooves 2 and 13 have the same number of sections 5 of different configurations that either repeat the configuration friend (Fig. 3), or have a mirror image of individual sections (Fig. 4).

 The launching ramp 7 has a second rectilinear ramp-up section 14 installed in the immediate vicinity and parallel to the first acceleration section 8, equal in length to the first and docked with the second groove 13, which passes into the finish area 10.

 The finish area 10 is divided into two disjoint finish lines 15 and 16, each of which is a continuation of only one gutter.

 The track has an optical system for informing about the relative movement of athletes during movement along the track (Fig. 6, 7, 8), which contains stationary sensors 17 discretely mounted in each gutter, fixing the passage of the sled (bean) along the entire length of each gutter and connected with sensors 17, light indicators 18 located in the visibility range of both athletes and spectators moving along the gutters.

 For example, on the sides 4 of each gutter 2 and 13, in a place accessible for visual observation of athletes and spectators, channel 19 with a transparent protective coating 20 can be made, and light indicators 18 are placed inside each channel 19.

 In each channel 19 two rows of multi-colored light indicators 18 A and 18 B can be placed (Fig. 7), one of which (one row of indicators) is connected to the stationary sensors of the first trench 2, and the other row of indicators is connected to the stationary sensors of the second trough 13 .

 An electronic scoreboard 20 (Fig. 1 and 8) connected to the optical system is installed at the finish area, showing during the race the movement of each sled crew (bean) until the finish line is reached through the light indication 21 and 22, which imitates the profile of the track and the movement of each bean on it both ahead of schedule and late.

 In the foundation base (Fig. 2), pipelines 23 for removing refrigerant are looped with a refrigeration unit 11. Pipelines 12 for refrigerant are installed on the sides and bases of each trough, as shown in the example of FIG. 2, and the pipelines 23 for the removal of spent refrigerant, it is advisable to withdraw from the cooling zones (sides and bottom) in the lower part of the foundation base.

 The principle of competition between the two teams does not require detailed explanations and is as follows.

 At the same time the teams start from the starting flyover 7, sledges or beans (not shown in the drawings) move along the gutters 2 and 13 towards the finish area 10, which is divided into two disjoint sections 15 and 16 to prevent collisions between sledges or beans at the end of the race.

 The movement of the sled or bean is monitored by sensors 17, determined by the light indicators 18 and transmitted to the electronic scoreboard 20, showing the progress of the competition.

 When equipping the gutters with two rows of multi-colored light indicators, FIG. 7, athletes and spectators have the additional opportunity to monitor mutual relative movement. So, if the red indicators track the movement of one team, and the green indicators track the movement of the other team, in each gutter two “running” light paths (one and another) will move ahead or behind the board, and athletes and spectators will be able to visually control the course of the competition.

The length of each gutter in accordance with international regulations is 1200 meters, with a height difference of 102 meters and an ice freezing surface of 9.6 thousand square meters for two gutters. Gutters can be made both in the form of a monolithic seamless reinforced concrete structure, and using other modern materials. The freezing of the route is artificial, for which a refrigerator is located in the finish area, the building volume of which is 10 thousand cubic meters. m. To increase the functionality of the refrigerator and the commercial potential of the entire complex, a refrigeration center with a volume of 5.0 cubic meters can be placed next to the refrigerator. m, designed for freezing and storage of agricultural products. For filling ice on the route, irrigation water supply is provided for a length of 1.5 km using artesian water from the well. The freezing surface is 9.6 thousand square meters. m for two gutters. The optimum ice temperature is from -2.5 to -6 ^o C. During one competitive training period (8 months), one ice is poured. As necessary, to maintain the surface of the ice in normal condition, it is supposed to re-fill the ice cover.
