The invention relates to the field of hydraulic engineering construction and can be used during the construction of long-term hydraulic structures during the development and construction of shallow sites, for example in the extraction and deep processing of hydrocarbon raw materials, during the construction of the hatchery industrial complexes, in particular, during the construction of artificial Islands.

There is a method of construction of hydraulic structures in the shallow water area in which the base pontoons towed to the place of erection of waterworks, mounted vertically piles, and basic pontoons rigidly fixed to adjacent to each of the piles (see RF patent 2159320 C1, E 21 In 15/02, 20.11.2000). This method is closest to the proposed combination of essential features and adopted as prot, as well as the high cost of construction of hydraulic structures.

Task to be solved by the claimed invention is directed, simplifying installation, reducing time and complexity of the construction of hydraulic structures, as well as to improve the reliability of the structure.

The problem is solved in that in the method of construction of hydraulic structures in the shallow water area, including basic towing pontoons to the place of construction of hydraulic structures, installation of vertical piles and rigid attachment of the base pontoons adjacent to each of these piles, according to the invention, to the place of erection of waterworks tow floating concrete matrix pontoon width equal to the width of the base of the pontoons and which is equipped with rastvorobetonny node and equipment for casting and installation of piles and loaded piles in the form of pipes, the last set vertically along the two sides of the concrete matrix pontoon symmetrically relative to its longitudinal axis and into the cavity of the tubes pour the concrete mix, matrix, the pontoon is moved to a new position and as stated above mount the following groups of piles along its two boron is Amy and rigidly secure each of the pontoons to the adjacent piles, inside each of the basic pontoons loaded weight of the ballast, and then, on the base pontoons create the payload. In some cases, of the complete method payload on the base pontoons create by placing them production equipment and/or education landscape and architectural forms. At least one of the free sides of the base of the pontoon are fixed rigidly with removable hinged floating concrete pontoon.

In Fig.1 shows a diagram of installation of pile-forming pile field;

in Fig.2 - scheme of installation of the base of the pontoons between the piles;

in Fig.3 - basic pontoon located on it payload;

in Fig.4 is a basic pontoon attached to the free sides hinged floating concrete pontoons.

For the construction of hydraulic structures in the shallow water area use basic pontoons 1 of the same width. When this construction is carried out using a matrix of the pontoon 2, the width of which is equal to the width of each of the basic pontoons 1.

To the place of erection of waterworks tow floating concrete matrix pontoon 2, which is equipped with AR (rastvorobetonny node) the CSOs and right) of the matrix of the pontoon 2, which are essentially guides for piles 3, mounted vertically symmetrically relative to the longitudinal axis 4 of the specified pontoon 2 pile 3. To do this, first set the vertical pipe, and then to increase the weight of these pipes, as well as to ensure the rigidity of the pile 3 in the cavity through the feeder AR pour the concrete mix. Designed piles 3 under its own weight zadumivaetsa in the ground 5. If the soil 5 very solid and the weight piles 3 is insufficient, provide additional push her with additional cargo. Piles 3 can be mounted simultaneously on the two sides of the matrix of the pontoon 2.

Then the matrix pontoon 2 tow to the new position 6 according to the plan, and as stated above along two of its sides are mounted next group of piles 3: first set of tubes, and then into the cavity of these pipes through the feeder AR pour the concrete mix. Moving matrix of the pontoon 2 in the new position is terminated by the formation of a pile field 7. Matrix pontoon 2 is given in area waters near the pile field 7, but free from piles 3.

Then the estimated number of base pontoons 1 towed to the pile field 7, alternately one after the other slid between symmetrica, either welding or flanges, or any other known method.

Then in the hold of each of the basic pontoons 1 load weight ballast. For example, towed along the other side of the pile 3 matrix of the pontoon 2 through the feeder AR inside each of the basic pontoons 1 pour the concrete mix. Thus there is a further push into the ground 5 vertical piles 3, attached to the base pontoons 1, up to the point of contact of these pontoons 1 with the bottom 8 of the waters.

Then on the base of the pontoons 1 place the necessary production equipment and/or form of landscape architectural forms, thereby impacting the base of the pontoons 1 payload 9 and pressing them tightly to the bottom 8 of the waters and podavlivaya them in the ground 5. The number, diameter and depth of piles 3 are determined on the basis of the mass is filled into the cavity of the 3 piles of concrete mixture, the mass of the top add-ons in the form of a payload of 8 and geological conditions.

To free the sides 10 of permanently installed on the ground 7 of the base pontoons 1 can be rigidly docked with removable hinged floating concrete pontoons 11. These hinged pontoons 11 may differ from the base of the pontoons 1 in size and pharmaciescom structures designed for retrofit hydraulic structures and based on them interchangeable elements infrastructures and lightweight architectural forms.

The described method allows to build hydraulic structure on the bottom with any on the hardness of the ground water, with a guarantee of its stability during operation. Because the width of the matrix of the pontoon and the width of each of the base pontoons are the same, this width determines the distance between the symmetrical piles and allows to keep this distance constant, reduces the time for determining the positions of the symmetric piles. In addition, the installation of piles simultaneously on two sides of the matrix pontoon also saves the time of the erection of waterworks. As a matrix and the base of the pontoons are encouraged to use the well-known standard pontoons, which saves money on creating unique and expensive constructions. The use of hinged floating concrete pontoons optionally allows you to easily increase or update erected hydraulic structure.
