A device to protect the base of the river Bank protection structures from undermining [1] , which is a solid flexible design protivogrippoznogo device, providing reliable protection shore protection structures in terms of rivers, flood flows which are characterized by high abrasive and transporting abilities. The device consists of a gabion mattresses, horizontally located in the side of the river channel associated with the protected structure with adjustable links and the top of which is attached recycled tires, which are interconnected by longitudinal and transverse rebar, forming a linked grid and passing along and across the rows of tires through the middle of the tread portions of the tires on their diameter. When the silt channel formed in the funnel is the self-absorption of the mattress with prigruzkoj, starting from its end.

The disadvantage of this technical solution are: - a large mass of buildings and therefore large specific load on the Foundation soil; - the complexity of the structures due to the large number of different materials, in particular the use is not always available and spread of poulsard, and when large deformations are possible gap gabion mesh; - the proposed solution does not provide prevention from erosion of the wall along the entire length, as it is not a continuous apron hinged adjacent to the retaining wall.

The closest technical solution is hydropower construction [2] , including fixed on the coastal slope of polonaruwa stepped design of concrete and reinforcement, with increasing toward the shore by the height of the steps and separated structural expansion joints on the interconnected blocks.

The disadvantage of this technical solution are: - the possible utility of the end of spurs jet stream flow over the barrier, representing spur and because of this, burying her down and violation of the integrity of structures; - a large mass of buildings and therefore large specific load on the Foundation soil, contributing to the degradation of structures and lowering down; - the relative complexity and economiccost technical solutions.

The purpose of the invention is improving the reliability and reducing the complexity of the construction.

This goal is achieved by the fact that riding a slope of the dam is fixed polysaprobic across a flowing stream, and the distance between them depends on the length of poulsard to metaprogram space formed stagnant zone for the deposition of particles in suspension, which under the action of its own weight begin to precipitate. The regiment is a flexible Foundation, broken structural expansion joints on blocks that are interconnected with all four sides of the mesh. Flexible Foundation helps to reduce the specific load on the Foundation soil from the action of its own weight polysaprobic and thereby reduce utility under the facilities and the rate of deepening of polysaprobic in the soil over time.

At the front end polysaprobic adjacent flexible apron having a rectangular shape and overlying the possible washout pit. Flexible apron broken structural expansion joints on the interconnected mesh integrated blocks. When the deformation of the flexible apron design integrity is not violated because the relationship of each individual block on all four sides of the reinforcing mesh to the adjacent blocks. Polonaruwa comes in riding the slope of the dam and secured it. At the front end polysaprobic flow rate, the ena starts to fall down and to prevent possible deformation of polysaprobic. While the apron, dropping down when washouts, after some time starts saratica and becomes the anchor. Possible deformations of the structures of polysaprobic not violate the structural integrity and do not affect its operation due to the presence of structural joints, making the structure of your building flexible and changeable. Individual structural blocks interconnected mesh, which makes the design polysaprobic flexible.

Block design polysaprobic increases its flexibility and changeability. Polysaprobic change the kinematic structure of the stream in such a way that the coastal part of an earth dam formed stagnant zones and stops the process of erosion, and in the immediate vicinity of the contact polysaprobic and dam from downstream side begins the process of silting. Suspended and transported particles under the action of its own weight begin to precipitate from a reduction in force weighting caused by the reduced flow rate.

The presence of the shelves, which acts as a flexible Foundation, lowers the center of gravity of the cross-section and makes the structure more resistant to possible static and deformation changes.

In Fig.1 shows a plan of the dam with IG.2 for option, when the regiment is formed by joining two wing; Fig.4 - section b-b of Fig.2 for the variant when the regiment is formed by joining two wing; Fig. 5 - section a-a in Fig.2 for the variant when the shelf is integral with the wall structure and decreasing the width of the wall upward, and Fig.6 - section b-b of Fig.2 for the variant when the shelf is integral with the wall structure and decreasing the width of the wall upward, and Fig.7 shows an axonometric view coastal defences.

Hydropower facility consists of loose dirt dam 1, horseback slope 2 which wedged polonaruwa 3, consisting of 4 blocks. Cross section polysaprobic 3 has Tauri form, the wall 5 is oriented upward, and the shelf 6 is adjacent to the bottom of the base. Shelf 6 can also be formed by the junction of the two wing 7 to the wall 5, and between them there may be structural expansion joint 8. Polonaruwa 3 broken transverse structural expansion joints 9 blocks of 4, interconnected mesh 10. In the shelf 6, which is a flexible Foundation provided by the reinforcing mesh 11. From the front side of the shelf 6 is adjacent flexible apron 12.

Hydropower construction, we have Tauri cross-sectional shape and shelf 6, oriented down. Polysaprobic 3 are installed across a flowing stream at an angle of 15-20oto the transverse axis, and the distance between them depends on the length of poulsard 3 so that megaprogram space is formed stagnant zone for the deposition of particles in suspension, and which under the action of its own weight begin to precipitate. Shelf 6 is a flexible Foundation broken structural expansion joints 9 units 4, which are interconnected on all sides of the reinforcing mesh 11. Flexible Foundation 6 allows to reduce the specific load on the Foundation soil from the action of its own weight polysaprobic 3 and wall 5, thus preventing utility under construction and the rate of deepening of polysaprobic 3 in the soil over time during the operation.

At the front end polysaprobic 3 adjacent flexible apron 12, having a rectangular shape and overlying the possible washout pit. Flexible apron 12 is split structural expansion joints 9 are interconnected mesh 11 integrated blocks. When the deformation of the flexible apron 12 structural integrity is not violated because the relationship of each individual block with all chetyrekh it. At the front end polysaprobic 3 flow rate flowing round her grow and begins the process of the degradation of a flexible apron 12, which under the action of its own weight starts to fall down and to prevent possible deformation of polysaprobic 3. Flexible apron 12, falling down when washouts, after some time starts saratica and turn into the anchor. Possible deformations of the structures of polysaprobic 3 does not violate the structural integrity and do not affect its operation due to the presence of structural joints 9, making the structure of your building flexible and changeable. Individual structural blocks interconnected mesh 10, which makes the design polysaprobic flexible.

The presence of shelves 6, which is the Foundation shifts down the center of gravity of the Tauri cross-section and increases the resistance of polysaprobic from possible deformation of the changes caused by the influence of the water flow.

Block design polysaprobic increases its flexibility and changeability. Polysaprobic change the kinematic structure of the stream in such a way that the coastal part of an earth dam formed stagnant zones and stops the process of erosion, and in neposredstvennaya particles under the action of its own weight begin to precipitate from a reduction in force weighing, due to reduced flow velocity.

The presence of the shelves, which acts as a flexible Foundation, shifts down the center of gravity of the cross-section and makes the structure more resistant to possible static and deformation changes.

The proposed design of the pier cross-section you can save money spent on the construction of polysaprobic construction material and make the design more efficient and reliable in operation.

This hydropower facility can be used in mountain and lowland rivers and as vypravitelnye structure for the regulation of riverbeds.

Hydropower construction will provide protection from erosion of the dam and flooding when flood costs, settlements, falls into this area.
