The method of erecting the protective structure includes delivering the box 15 to the construction site afloat and installing it into the structure in a semi-loaded vertical position using erection pontoons 23 ballastir. To do this, before launching the box 5 into the water from the pontoons 23 through the mounting platform devices are fastened on the outer surface of the walls of the box on both sides. Simultaneously with the unfastening of the pontoons 23, flexible connections are mounted, which are dismantled before installation of the box 15 to the design position, and after its installation is completed, they are re-mounted. Special mounting tools allow you to dismantle the pontoons 23 with the least effort. 2c. and 3 3.p. f-ly, 4 ill.

The barrier structure includes pile supports 1, transverse 2 and longitudinal 3 connections, made in the form of beams pivotally connected to the pile supports and between themselves, wedge-shaped ballast containers 4 with loading 5, mounted on pile supports 1 using clamps 6 and moved along it by hinged movable supports 7. The pile supports 1 are provided with a rectangular support 8 fixed to them in the form of a plate with a hole, the upper 9 and lower 10 are wedge-shaped and the stops in the form of plates, while the stop 9 has a cut-out below 11. Top structure n edstavl is a concrete box, a plate which is divided into compartments 12, zapolnetpgye sand, and comprises two shafts 13 and two notches 14. 13 zaiolnet Mines, concrete. The walls of the box 15, owner) chi (1c waveguide - P1IMI screens, made with through Holes 16, installed below by means of flexible connections 17, having

recesses 8 and provided with rods 19, support plates 20 and nuts 21, which are placed in the notches 14. On the outer surface of the boxes 15 there are fasteners 22 with openings, which serve to secure the ballast pontoons 23 when the box is transported. On the surface of the pontoons 23 there are fixed stops 24 with holes. Through the holes in the stops 22 and 24 missing screws 23 with thrust heads 26, Screws 25 are equipped with nuts 27,

Wave visor 28 is secured in the sites of grouting pile supports.

The construction works as follows.

From the effect of wave load (or ice pressure) on wave-suppressing screen box 15, the ground medium and pile foundation of the structure are activated. Under the influence of the wave load, the pile supports 1 produce varying magnitudes and directions of force transmitting large pressures to the soil under the pile foot. The soil, deforming, causes the pile support 1 to sink, as a result of which the axis of the hinge-movable support 7 engages with the notch 11 of the support 9, and as a result, the container 4 tends to move downwards. However, this movement is hampered by a large frontal drag on the surface of the container. Under the action of an external load on the structure, there is also a significant resistance of the soil to the displacement of the structure in the horizontal direction, due to the lateral surface of the containers 4 and the pile supports 1.

Due to the monolithing of the heads of the pile supports and the compression of the box by means of flexible connections 17 of the wall of the box 15 under the action of an external horizontal load on the structure, they work together with the pile supports I, as a result of which the bearing capacity of the pile supports and the rigidity of the structure as a whole are increased.

The construction of the structure is carried out in the following sequence.

After immersion by means of the guide device of the floating conductor of the pile supports 1 into the ground, 164

Installation of transverse 2 and longitudinal links 3, and then ballast containers 4. Containers 4 ballast, and they under the action of their own weight and partial load 5 move along pile supports 1 to the design position. Thereafter, containers 4 are completely filled with load 5,

On the pile site, where the upper structure of the structure is manufactured in advance, ballast-mounted pontoons 23 are mounted, which are then fixed with the help of stops 22 and 24, screws 25 and nuts 27 on the surface of wave-extinguishing screens-boxes 15. Simultaneously with this operation, flexible 17 and 19 and the tension is carried out with the help of the support plate 20 and the nuts 21. After these installation operations are completed, the box is lowered into the water and transported to the construction site. The dismounting of the flexible links 17 is carried out and the box is moved to its original position above the installation site. The pontoons 23 are ballast and the box is lowered to the design position. The reassembly of the flexible connections 17 is carried out with the rods 19. Then the mounting of the baffle plate 28 and the homonolation of the heads of the pile supports 1 with concrete in the mines 13 are carried out and the compartments 12 are filled with sand.
