Floating dock section

FIELD: transport.

SUBSTANCE: invention relates to ship building. Floating dock section contains pontoon where side towers are installed, ballasting facilities, dock floor with primary framing made as structure of longitudinal and transverse frames, main framing beams resting on it on which beams the decking is placed. The pontoon is divided into central and side ballast compartments by vertical waterproof bulkheads.

The invention relates to shipbuilding and for the design of floating docks.

Well-known section of the floating dock containing side of the tower and pontoons, divided by a longitudinal vertical watertight bulkheads at the Central and side ballast tanks, means for ballasting the dock and berth - deck, containing a frame set in a frame of longitudinal and transverse frames, leaning against him cross the core set, hosts deck flooring (see "floating dock No. 220, project FD 220. Steel, non-self-propelled floating dock lifting capacity of 27000 tons built in July 1969 at the shipyard Oresundsvarvet AB Gotaverken (glandstone, Sweden) on the class Lloyd's Register).

Also known section of the floating dock containing side of the tower and pontoons, divided by a longitudinal vertical watertight bulkheads at the Central and side ballast tanks, means for ballasting the dock and berth - deck, containing a frame set in a frame of longitudinal and transverse frames, leaning against him longitudinal core set, hosts deck flooring (see "floating dock PD-83 m, the project S878. Steel, self-propelled, floating dock lifting capacity of 25000 tons built in August 1965, at the shipyard of Mitsubishi Heavy Industries, Ltd. (Yokohama, Japan) on the class Lloyd's Register).

The disadvantages of the known technical solutions aplaydevices damaging structural elements of the most loaded during finishing operations of the Central compartments, the low resistance of the decking when the longitudinal system of recruitment and high attrition towers from equipment movement in the transverse system, a complex system of ballasting dock, leading to asymmetric filling of the compartments and overload structures compartments. In addition, the large distance of the longitudinal vertical watertight bulkheads from the longitudinal vertical plane of symmetry of the pontoons is not possible to provide reliable support for dock cells in the production of small and medium ships.

The challenge which seeks the proposed technical solution is to increase the strength and reliability section of the floating dock by combining systems set the boat-deck pontoon dock, join the Central compartments into one and reducing the width of the Central compartment.

Technical result achieved when the solution of the problem, reflected in the increasing stability of the flooring of the boat-deck in the center of the pontoon and reduced abrasion of the towers when the movement of the vehicle, reducing congestion compartments and simplifying control ballasting reducing the number of elements of the ballast system and reduce the likelihood of asymmetry ballast and roll dock. Furthermore, the reduction in size of the Central compartment allows you to position the longitudinal bulkhead closer to vertical prodol the second plane of symmetry of the pontoon, that makes it possible to provide a reliable support for dock cells in the formulation of medium and small vessels. The use of longitudinal system set in the side compartments instead of the lateral system reduces overall weight of the pontoon.

The problem is solved in that section of the floating dock containing side of the tower, placed on the pontoon, which is divided into longitudinal vertical watertight bulkheads in ballast tanks, means for ballasting the dock and berth-deck, containing frame set, made in the frame of longitudinal and transverse frames and deck flooring placed on the beams of a core set supported on the frame, characterized in that the vertical longitudinal plane of symmetry of the pontoon is placed vertical retaining bulkhead, made permeable, while the relative width of the Central ballast compartment defined by the formula:

wherethe relative weight of the tower dock;

the relative weight calculation of a ship;

the relative distance to the center of gravity of the tower from the outer wall of the dock;

- the ratio of the critical stresses for the flooring of the boat's deck to the calculated normative yield stress normal is between voltages;

the relative bending moment in the transverse plane of symmetry of the pontoon;

The p - weight of the dock;

In - the width of the dock;

Pb- weight of the tower;

Pc- the estimated weight of the ship;

Inb- distance to center of gravity of the tower from the outer wall of the dock, and the walls of the Central ballast compartment is made in the form of a longitudinal vertical watertight bulkheads, equidistant from the vertical retaining bulkhead, with a core set of Central ballast compartment are designed for cross air flow, and on-Board ballast compartments - longitudinal schema.

Comparative analysis of the essential features of the proposed solution with essential features unique and prototype demonstrates its compliance with the criterion of "novelty".

The characteristics of the characterizing portion of the claims, solves the following functional tasks.

Signs "...in the vertical longitudinal plane of symmetry of the pontoon is placed vertical retaining bulkhead, made permeable..." aims at bringing more loaded during finishing operations of the Central compartments in one, allowing you to more easily control the ballasting and reduce congestion compartment. This reduces the number of elements of the ballast system of the dock and reduces the likelihood of asymmet the AI ballast and roll the dock.

The mathematical formula will calculate the relative (to the width of the dock) the width of the Central compartment (plot size with the cross-system).

Signs "...the walls of the Central ballast compartment is made in the form of a longitudinal vertical watertight bulkheads, equidistant from the vertical retaining bulkhead..." can provide reliable support for dock cells in the production of small and medium ships.

Signs "...a core set of Central ballast compartment are designed for cross-scheme..." provide better perception of the compressive effort slipway-deck that occur when the transverse deflection of the pontoon from the action of the weight of the vessel.

The longitudinal system set in the side compartments can reduce the abrasion of the berth-deck welding in places set in motion machinery mainly along the towers of the dock.

To combine more loaded during finishing operations of the Central ballast compartments 9 in one in the vertical longitudinal plane of symmetry 11 of the pontoon 1 is placed vertical retaining bulkhead 12, made permeable. Relative to the width of the dock) width of the Central ballast compartment 9 (plot size with the cross-system) calculated by the mathematical formula. Longitudinal vertical watertight bulkheads 8 placed at equal distance from the vertical retaining bulkhead 12 (according to the calculation). The main set of 6 Central ballast compartment 9 is executed on a cross air flow and provides a better perception of the compressive effort in deck deck 7 arising from the transverse deflection of the pontoon 1 from the action of the weight of the vessel and on-Board ballast compartments 10 - longitudinal pattern. The longitudinal system of the main set of 6 onboard ballast tanks 10 allows smart is to sew abrasion deck 7 at the welding set in motion machinery mainly along the side of the towers 2 dock. In addition, the use of longitudinal primary set of 6 reduces the total weight of the pontoon 1.
