The invention relates to shipbuilding and can be used primarily in the construction of floating docks of heavy payload.

The purpose of the invention is to increase operational efficiency by the possibility of carrying out repair work in the underwater part of the main section while at the same time docking ships.

FIG. 1 shows the position of the end section connected to the main (central) as a carrier platform; in fig. 2 - position of the end section under the bottom of the main section for work in the underwater part on the main section (a - general case, b - installation of the section under the tip of the middle section using a temporary structure - end wall, installation of the section below the tip of the middle section using trim ); in fig. 3 - a dock with a view of the end section installed under the bottom of the main section, cross section; in fig. 4 - mounting unit of the end sections of the base section to the slipway of the end section; in fig. 5 shows the design of a butterfly valve with a drive and a compactor; in fig. 6 shows the design of a seal assembly between the end-section berth and bottom of the middle section; in fig. 7 shows the structure of the sealing unit of the vertical end of the sash (the dash-dotted line is the position of the outer side of the tower of the main section); in fig. 8-additional pipelines of the ballast system of the end section; in fig. 9 is a section A-A in FIG. eight.

The floating dock contains the main (central) section 1, end section 2, area of the caisson 3, working chamber 4 of the caisson, butterfly valve 5, sealing stationary walls 6, support device 7, drive mechanism 8, sealing device 9 slipway deck of the end section , rubber strip 10 of shaped profile of sealing device, steel clamping strip 11, additional bypass pipeline of ballast system 12, locking device 13, drain pipes 14, additional bypass pipeline 15, locking device 16 , outlets 17, connecting sheets 18, the bottom 19 of the end part of the tower of the main section, the shaft 20 of the caisson, the end wall 21.

The dock works as follows.

To dock work on section 1, section 2 is disconnected by cutting connecting sheets 18 from the deck of section 2, the locking device 13 is opened and section 2 is submerged with a ballast pump to the depth corresponding to immersion of the deck of section 1 (for 300-500 min). Section 2 is driven by pulling under the bottom of the section of the section being repaired. Section 2 under the section of the section to be repaired is initially pressed by the ends of the section 2.

the sealing wall 6 to the outer side of section I. Then the ballast is pumped out of the compartments of section 2 and the section is pressed by the sealing device 9 to the bottom of section 1, the closures (fore and aft) 5 are closed by means of actuators and, thus, sealing around the entire perimeter of section 2. The locking device 13 is closed, and the device 16 is opened and the water from the operating chamber of the caisson 4 through pipes 14, 12, 15 and 17 is bypassed into the ballast compartments. The working chamber 4 of the caisson is ready to work with it. Repair crews, equipment and materials are sent to the working chamber of the caisson through the shafts 20. Section 2 is moved to a new repair site after ballasting and decompaction.

The order of withdrawal of section 2 from under the bottom of section 1 is performed in the reverse order.

Reception of ballast begins by opening the locking device 13, water enters the working chamber 4 (device 16 is closed). Section 2 with a certain amount of ballast in the compartments is brought to its place and, with the help of connecting sheets 18, is attached to the bach section 1 after appropriate pumping of the ballast and pressing section 2 to the bottoms 19.

To repair the end wall of section 1, a temporary structure of the end wall 21 is used on section 2 or section 2 with trim is installed (Fig. 2c). For a dock with two end sections 2, in addition to speeding up repairs — simultaneously from two working areas, it is possible, if necessary, to lift section 1 above the water.

5 In this case, the carrying capacity of the two sections 2 must be sufficient to lift section 1 above the water.
