(54) METHOD OF CARRYING OUT VESSELS UNDER THE BRIDGES

one

The invention relates to the field of water transport, in particular to methods of escorting ships under bridges.

A ship gateway is known for posting ships under bridges, containing an airborne 5 ballast tank and a lock gate, two identical sections, with the lock gate being mounted in both extremities of each section of the river}.

The lack of a sluice ship concludes 10 seconds in that it is a complex hydraulic structure. The length of the device must be at least 2.5-3 of the length of the largest vessel. Accordingly, a significant amount of hydro-5 technical and construction work. A large amount of water must be pumped out to guide ships, necessitating the use of pumps.

high performance. Device 20 can be used only in one place of the water area.

The closest technical solution is the method of escorting ships under bridges using a surface chamber 25, equipped with ballast compartments, filled with water and filled the chamber with water up to the level of the water area, the bataport is opened, the ship is closed into the chamber, - thirty

The chamber’s ballast compartments are filled with water, the camera is guided under the bridge, the ballast compartments are drained until the chambers ascend to their original position, open the boat port and lead the vessel off.

The disadvantages of this method are the large time spent on pumping water from the chamber to the side compartments, the floating sluice and the difficulty of fixing the vessel in the floating chamber

the gateway when the level changes

the camera,

The aim of the invention is to reduce the surface vertical dimension of the vessel being conducted relative to the water level.

The goal is achieved by the fact that according to the proposed method, after the vessel is loaded into the chamber, the ballast compartments of the chamber are filled with water from behind the board, and after posting the ballast compartments are drained overboard.

FIG. 1 shows the vessel in front of the bridge; in fig. 2 - a vessel prepared for pilotage under the bridge; in fig. 3 - ship after laying under the bridge; in fig. 4 - vessel prepared for access to the water; in FIG. 5, section A-A in FIG. 3. The floating dock 1 of the double-deck structure contains the right 2 and left 3 bataports fixed on hinges 4 and hermetically closing the dock mechanism for lowering and lifting the batho ports 5, ballast compartments and systems for receiving and pumping ballast 6, and securing the vessel in the dock made of elastic shells. The power installation may be autonomous or have power supply from the coastal network. The movement of the dock can be carried out by means of propellers or the root system. Bridge 8 rises above water level 9, vessel 10 is at the dock, the level of which is equal to the water level in the reservoir. In order to guide the ship under the bridge, in the case when the height of the ship is greater than the clearance size, the dock 1 is located in front of the bridge and submerged in the water so that the dock berth is below the main line of the vessel. Mechanism 5 opens the right-hand batport and vessel 10 is introduced into dock 1. Bataport 2 closes, compressed air is supplied to pneumatic compensators 7, with which the vessel is fixed in the dock. With the reception of the vessel, into the compartments due to the side of the dock, together with the vessel, it is submerged to the required depth, forming a passage under the bridge. At the same time, the water level in dock 1 will be lower than the water level in the reservoir. If necessary, a passage to the bottom of the reservoir can be made to pass under the bridge.

J 7ff 7 By means of propulsion or the crust system, the dock with the vessel is moved under the bridge. After the ballast is pumped out, the dock emerges until the water levels in the dock and the reservoir are combined, the left bastard port 3 is opened, and the vessel is taken out of the dock. The invention The method of posting ships under bridges using a surface chamber equipped with ballast compartments filled with water, through which the chamber is filled with water to the level of the water area, the bataport is opened, the ship is brought into the chamber, the batoport is closed, the ballast compartment is filled with water The camera under the bridge drains the ballast compartments until the camera ascends to its original position, opens the boatport and leads the vessel, characterized in that, in order to reduce the surface vertical clearance of the vessel being carried, the water level no, after winding of the vessel into a chamber filled with ballast water compartments chamber due to the bead, and then dried wiring ballast tanks overboard.
