The invention is combinational, because it uses some of the known device in a new, previously unknown combination, giving a completely new effect.

The invention relates to road construction, in particular to the creation of floating roads and highways for land transport in specific conditions: not samartaudio the riverbed downstream of the Siberian hydroelectric power plants (HPP).

The most similar solution proposed are floating bridges-tape. Famous pontoon bridges-tape, for example:

"Floating bridge-ribbon - inventor's certificate SU 1014311 A E01D 15/14, the authors Whitelaw, Intracanal (USSR), Zdero and Bpinow (BNR).

"Reinforced floating bridge-tape split system" inventor's certificate SU 1336637 A1, E01B 15/14, the authors Whitelaw and Intracanal.

"Floating bridge" - patent RU 2184809 C1 IPC E01B 15/14, the authors Malyshev A.A., Kupriyanov Y.A., icov AV, Trefilov V.F., chmelyk PS

Enough detailed classification and construction of floating bridges in the book "Pontoon bridges, ferry and ice crossing, Telow VI, Kanukov IM Ed. Whitelaw. M: "Transport", 1978, 384 S., and in the "Instructions for repair, maintenance and operation of ferries and pontoon bridges, VSN 50-87, the Ministry of car roads of the RSFSR, M., "Transport", 1988.

Known also hydrauli the mini drives converts the energy of river water flow into rotational motion of the drive shaft of the electric generator, for example:

"Hydropower plant to use the energy of water flow" - inventor's certificate SU 1442689 A1, F03B 9/00, authors Eggental and Vaginal.

"Floating HPS "Juvenal" - inventor's certificate SU 1753008 A1, F03 9/00, author Uscreates.

The main reasons for applying for the invention are as follows:

1. Known floating structures for movement thereon land transport, in the form of bridges and employees solely as crossings over water obstacles, connecting them to the opposite shore and having a longitudinal (axial) direction, as a rule, across the river.

2. In the famous bridges tape of the type used monohull floating bases with a variety of their location relative to each other when forming the ribbon bridge.

3. In the famous bridges belt type not used the possibility of using the kinetic energy of water flow to convert it into mechanical motion, such as rotational.

4. In the famous bridges-tapes of the roadway does not have a barrier between the lanes of oncoming traffic.

5. In known hydropower plants with a floating base in the ideal catamaran inner side hulls are parallel to each other and therefore water flow, passing between them, has a constant speed.

6. Energy for lighting bridge-tape and to work in his service must be supplied externally (electricity for General use).

The claimed invention is intended to solve the problem of construction of a highway through the creation of floating structures in the form of a tape having a longitudinal pontoon catamaran base type along (flow) of water, allowing you to build pontoon road of any length on the ice river located between the buildings pontoon catamaran base type devices for power flow of the river water, which is due to the changes in cross-sectional space between the sides of the boat increases speed and, respectively, the kinetic energy of the flow, and ProTeam canvas pontoon road installed the separation barrier, which allows to increase the transverse rigidity of the floating road in the connective elements of the pontoons.

The use of the proposed technical solution will allow the construction of the road floating type using United in the tape along a river pontoon catamaran base type, between the inner sides of which are hydraulic actuators for the power take-off of water flow, which is due to narrowing of the internal is their sides of the catamaran has a variable cross-section to increase the velocity of the flow of water, and on the road carriageway along the road mounted the separation barrier, creating a transverse rigidity of the floating structure.

The invention is illustrated by drawings, which depict: 1 - floating hydropower road, top view; figure 2 - double pontoons (catamarans) roads floating type, incision catamaran in the plane of the waterline; figure 3 - cross section of a floating hydropower road; 4 - floating hydropower road, side view of the docking sites catamarans.

Floating hydropower road consists of floating links (catamarans), collected in the tape 1 along the river (figure 1). Each filler element is a double-hulled pontoon (catamaran) 2 having between buildings narrowing of the inner flanges 3 and extension of the exterior sides of the hulls at the bow 4, where between the aft transom housings (aftershave) ahead of the pontoon 5 and nasal parts (forsterei) buildings standing behind pontoon 6 has a space for the passage of the water flow generated by the flow of the river, the distance between forsterei buildings standing behind the catamaran is greater than the distance between aftershave ahead catamaran (figure 2). The presence of a constriction between the inner the orts catamaran and additional pressure from the side intake increases the rate of water flow in the installation place of the hydraulic cylinders 7 for power generation (mini-hydro). The roadway 8 hydropower floating roads made in the form of grooved concrete structures of the type having a vertical separator 9 and sides 10 fencing role of the ribs between the compounds of the pontoons (catamarans) and in addition to creating conditions for the safe movement of vehicles transverse rigidity pontoon road in places docking bridge boats (catamarans). With the shore and pontoon road connects special wjezdne-exit constructs soil or pile type 11 (figure 1).

The proposed floating hydropower highway is arranged in the riverbed downstream of large hydroelectric power plants, in particular Krasnoyarsk, Bratsk, or other geographical Feature of these places is that the riverbed is usually located in mountainous terrain and at low winter temperatures of atmospheric air water of the river below the dam HES never freezes. For example, the Yenisei river below the dam Krasnoyarskaya HPP does not freeze over a length of over 200 km of channel. Under these conditions, the application of the proposed pontoon road is very efficient for the following reasons.

First, the cost of 1 km of floating road about 2-3 times less than the cost of 1 km of overland road similar parameters (width, floor and others). At Russian prices, the cost of 1 km of land is broadband asphalt road is from 510 to 960 million. On the Central TV channels of Russia in the print media ("MK" for 30.06. - 7.07. 2010) was named the figure of $17 million, and in the "AIF" and more - $32 million (No. 28, 2010) per 1 km of road.

Secondly, the track is floating roads laid on the river bed and therefore has no sharp turns, there are almost no UPS and downs, and in the alternative overland route in the rugged mountain terrain is usually much shorter, such as the distance along the bed of the river Yenisei from Krasnoyarsk to Divnogorsk 22 km and land highway 46 km

Thirdly, greatly simplifies maintenance of the road in floating performed to eliminate the products of precipitation, because the location of the road on the water does not require a different drainage and drainage devices inherent in overland road.

Fourth, floating in the road there is no need for the construction of small bridges and crossings over small rivers and ravines.

Fifth, the presence on the pontoons and pontoon road hydro installations PTO water flow allows you to not only have electricity for lighting and maintenance of the highway, such as heated cloth road during icy conditions, but also to sell surplus electricity. When installing, for example, generators in floating levels autodo the OIG from Krasnoyarsk to Divnogorsk unit capacity 50 kW will receive a total installed capacity of 125 mW, that would be consistent with middle power plant.
