The result is a fortified artificial seaweed underwater coastal slope. 1 C.p. f-crystals, 7 Il. The invention relates underwater coastal slope of the pond.There is a method to prevent erosion of the submarine coastal slope, which provides the accumulation of sediment on the bottom of the reservoir and dynamic stability of the protected areas of the coastal zone 
The proposed solution is carried out by known methods, does not provide sufficient fixing artificial algae on the bottom of the reservoir, which leads in some cases to the total destruction of Bank protection structures under the influence of wave action.The closest in technical essence of the present invention is a method of strengthening the underwater coastal slope artificial seaweed 
The strengthening of the underwater coastal slope artificial seaweed carried out by a known method, included pre-production of artificial algae from propylene foam in the form of strips with cross-sectional sizes 5,00,1 mmStrips of artificial seaweed collected into bundles, each of which consisted of 890 strips length 1.8 m Bundles of artificial seaweed was reinforced metal structures at different distances from one another.Metalli on the bottom of the reservoir with a floating crane in the distance 180-245 m from the water's edge.However, if an active wave impact on the Foundation soil of the submarine coastal slope known technical solution also did not provide a reliable fastening of the spatial structure on the bottom of the reservoir, especially during the installation of such devices on the loose unconsolidated soils. When this metal structures did not have strong enough ties with the bottom due to its low strength and deformation properties.In addition, the structure for attaching the artificial seaweed left on the bottom of the reservoir, has experienced a significant wave action, which often led to them overturning and destruction.The aim of the invention is to increase the efficiency of fixing artificial algae on the bottom.The aim is achieved in that in the known method of strengthening the underwater coastal slope of the artificial pond algae, including the Assembly of strips of floating material in the beams, the connection beams bands with the bearing structure by means of mounting elements and lowering the supporting structure with the beam strips on the bottom of the reservoir floating hoisting mechanism, the load-bearing structure perform multilevel the level, to which attach the bundles of strips and put the cords with a bunch of bands in the guide lugs of the bearing structure through all tiers, and after lowering the supporting structure at the bottom of the reservoir to produce liquefaction of the soil of the bottom of the reservoir by feeding him a high pressure water flow and vibration of the supporting structure, then the load-bearing structure with flexible cords and bundles of strips dipped in liquefied soil below the level of wave action on the bottom and fix the lower part of the cords with a bunch of bands in the soil through compaction by vibration of the supporting structure, feed the soil hardening mortar and strained, after which the carrier is extracted from the reservoir, missing cords with bunches of bands through the eye.In addition, prior to lowering the supporting structure at the bottom of the reservoir on the top tier of the fixed coil, which is wound the cords with a bunch of bands, when removing the bearing structure of the reservoir produce unwinding cords with bundles of strips, coils, and after removing the supporting structure of the reservoir cords cut at the level of the water surface.In Fig. 1 shows a diagram of the method for strengthening the slope of the artificial pond algae; Fig. 2 is unaudite blades, equipped with elements of the closed configuration of Fig. 5 section b-B in Fig.2; Fig.6 sealing blades spatial structure with wedge-shaped Central symmetrical bevels; Fig. 7 scheme of passing beams of floating material through the guide lugs sealing blades spatial bearing structure.Device for strengthening the underwater coastal slope includes (Fig.1) floating hoisting-and-transport mechanism 1, which provides a comprehensive work on the transportation to the place of construction of multi-storey spatial bearing structure 2 with bundles of strips 3, the immersion of the supporting structure 2 in the ground 4 of the reservoir, the fastening beams artificial algae (beams lanes 3) in zone 5 hardening below level 6 wave action on the ground floor, and also removing from the soil and the rise of the spatial bearing structure 2 above level 7 water surface.Spatial bearing structure 2 consists of a vertical hollow rod 8 with the vibrator 9 and the inlet pipe 10 at the top. In the lower part of the hollow vertical rod 8 is mounted on the head jetting nozzle 11 and the discharge valve 12.Along the NR is -15. The sealing blades 13-15 designed for deep compaction of saturated soil under the influence of vibratory oscillations of the vibrator 9, combined with the vertical movement of the supporting structure 2 in a certain mode dip and rise.Above the bottom layer of sealing blades 15 is tier injection tubes 16. The design and shape of sealing blades and injection tubes 16 are different. The discharge tube 16 is made of seamless steel pipes, oval, perforated along the entire surface. The sealing blades are made from steel strip and are wedge-Central - symmetrical bevels (Fig.6). Central-symmetrical bevels of americna with respect to the Central axis of the multi-tiered spatial supporting structure 2. The design of the sealing blades 13-15, made in the form of a centrally symmetric bevel, provides increased strength of the supporting structure 2 when it is vibrating the dip and rise in the ground. The discharge tube 16 and the sealing blades 13-15 are streamlined to reduce ground resistance at the implementation of the supporting structure 2 in the ground 4 the bottom of the reservoir and optimize the size of zone 5 hardening of the soil.In addition, to improve vibrometry soil hardening mortar, the ends of the injection tubes 16 and sealing blades 13 and 15 is provided with elements 17 of any length and configuration. It may be a closed execution (Fig. 4).On sealing blades 13-15 fixed guide lugs 18, for example, in the form of an annular lugs. In the guide lugs 18 posted by bundles of strips 3 with cords.The upper tier of the sealing blade 13 is fixed coil 19, which is wound, for example, in the form of strips, cords or bundles of artificial seaweed. Coil 19 is fixed on the sealing blades 13 so that the cords with bundles of strips 3 free uncoiled from the coil 19 and pass through guide lugs 18 from the top tier to the bottom.Thanks to its elastic properties of buoyancy and V-shaped design of the bundles of strips 3 when passing through the guide lugs 18 from top to bottom is compressed and passed through the eyelets, opens like an umbrella immediately at the exit of the guide lugs 18 (Fig.7). The lower end surface of the guide lugs 18 is a focus for rsta 15 promotes deep anchoring beams lanes 3 below level 6 wave action on the ground.For a complete elimination of the possibility of moving up fixed in the ground beams lanes 3 when removing the bearing structure 2 of alluvial soil under the lower sections of the sealing blades 15 on each cord or harness is installed, the locking element 20 (Fig.2).The method is as follows.Initially transported on floating hoisting mechanism 1 spatial load-bearing structure 2 to the construction site. Then produce liquefaction of the soil of the bottom 4 of the reservoir by submitting him in the discharge flow and vibration of the supporting structure 2.To do this, include the vibrator 9 and simultaneously create a high-pressure stream of water directed along the vertical hollow rod 8 through the discharge valve 12 and the tip of the jet nozzle 11 vertically down to the intensification of erosion dense soil layers 4 located below the level of 6 wave action on the ground. The special conditions under which the discharge valve 12 is that it skips the flow of water only when creating a high pressure, for example, more than 5 ATM, and closes at a lower pressure. This in turn allows to use this hydraulic feed and feed uprocess (not shown), connected high-pressure hoses to the inlet side 10 and a vertical hollow rod 8.Next, the carrier spatial design with 2 flexible cords and bundles of strips 3 are dipped in liquefied soil below 6 wave action on the bottom 4 of the reservoir under the action of its own weight and fix the lower part of the cords and bundles of strips 3 in the soil through compaction by vibration of the supporting structure, feed and soil hardening mortar and strained.After reaching the injection nozzles 16 spatial bearing design 2 design elevation of the top of the hardened soil, inlet pipe 10 is cut off from the high-pressure water pump and is connected to a source of injection of the hardening solution with a lower pressure. In this case, the discharge valve 12 is closed. A hardening solution, as well as high-pressure water stream, is fed through inlet pipe 10 and the vertical hollow rod 8 to the discharge tube 16 and then through the perforated holes of the tubes 16 in zone 5 hardening of the soil.Deep soil compaction is performed under the influence of vibrating sealing blades 13-15 Central symmetrical bevels, which the cyclic operation of the lifting and lowering of the spatial bearing structure 2 in a vertical plane at a certain distance (usually less than 0.5 m).After reaching the spatial carrier design 2 design depth below level 6 wave action on the ground, start extraction from a reservoir, passing the cords with bundles of lanes 3 through lugs 18 and simultaneously vibrating compaction sealing blades 13-15 ground when the vibrator 9. While the beams lanes 3 remain in the soil due to the construction disclosed beams, providing resistance due to the construction disclosed beams, resisting reverse movement of the spatial bearing structure 2, and the presence of the locking elements 20, which also reliable anchorage.In order to enhance the strength of the soil and increase the density of addition when pairing with bundles of strips 3 estimated elevations may change the rate of extraction of the spatial bearing structure 2, it stop or repeated immersion also when the vibrator 9. Maximum sealing effect is achieved after the occurrence of a phenomenon full of "failure" in vibration impacts at a given depth is the case in which the spatial substructure 2 starts to jump on one place without further verticalement (usually level 6 wave action on the ground) to stop the flow of the hardening solution and extracted spatial carrier 2 from the soil to the surface of the pond. This produces the unwinding cords with a bunch of bands with 3 coils spatial bearing structure 2 is already in the aquatic environment and moving them in the guide lugs 18 of sealing blades 13-15 in the direction from the top tier to the bottom to level 7 water surface.After extraction of the spatial bearing structure 2 from the reservoir cords cut at level 7 of its water surface, interrupting their length from the fixed end in the zone 5 of the hardening soil.Further spatial load-bearing structure 2 move floating hoisting mechanism 1 to a new location, set on the lower beams lanes 3 locking elements 20 and all operations are repeated in the above sequence on the entire area of strengthening the underwater coastal slope. 1. A way to strengthen the underwater coastal slope of the artificial pond algae, including the Assembly of strips of floating material in the beams, the connection beams bands with the bearing structure by means of mounting elements and lowering the supporting structure with beams strips on the bottom of the reservoir floating hoisting mechanism, characterized in that the load-bearing structure perform mnogaya cords, to which attach the bundles of strips, and pass through the cords with a bunch of bands in the guide lugs of the bearing structure through all tiers, and after lowering the supporting structure at the bottom of the reservoir to produce liquefaction of the soil of the bottom of the reservoir by feeding him a high pressure water flow and vibration of the supporting structure, then the load-bearing structure with flexible cords and bundles of strips dipped in liquefied soil below the level of wave action on the bottom and fix the lower part of the cords with a bunch of bands in the soil through compaction by vibration of the supporting structure, feed the soil hardening mortar and strained, after which the carrier is extracted from the reservoir, missing cords with bunches of bands through the eye.2. The method according to p. 1, characterized in that prior to lowering the supporting structure at the bottom of the reservoir on the top tier of the fixed coil, which is wound the cords with a bunch of bands, when removing the bearing structure of the reservoir produce unwinding cords with bundles of strips, coils, and after removing the supporting structure of the reservoir cords cut at the level of the water surface.
