Description

The invention relates to the field of hydraulic structures, in particular to floating berths.

Known stationary berths on a pile foundation (Goryunov BF et al. Sea ports. M .: Transport, 1979, pp. 218-220).

The disadvantages of the known berth are: large expenditures of time and materials for construction and dismantling associated with embedding of piles in the ground and installation of the hull on piles; the deck mark changes its value in relation to the surface of the water during high and low tides, therefore, a round-the-clock duty at the mooring lines is necessary; loading (unloading) of vessels with a horizontal method of loading (unloading) is difficult.

A floating pier (Pontoon floating structure) is known along a. with. USSR No. 515686, 1974, IPC В63В 35/36, В63В 35/42 containing a rigid waterproof case and ballast system.

Known berth according to RF patent No. 2009950 MPK B63 B35 / 34, 1990 contains a floating hull, in which a shaft is made from the bottom side, bounded from above by its deck. The support is made of hollow end-to-end telescopic sections inserted into one another and into the shaft of the floating hull. The specified technical solution provides the convenience of servicing ships at ebb and flow due to the filling of telescopic supports with water, which ensures a change in the level of the deck of the berth.

The well-known technical solution according to the RF patent No. 2009950 was taken as a prototype.

The disadvantage of the technical solution adopted for the prototype is the following. The known technical solution is difficult to use in the case of a deep water area at the location of the floating berth. In addition, it is impossible to ensure a constant level of the deck of a floating quay relative to stationary shore structures at high tide.

The purpose of the proposed technical solution is to eliminate the indicated disadvantages, namely, to ensure the use of a floating berth in areas with a large water area and to ensure a constant level of the floating berth deck relative to stationary coastal structures at high tide.

This goal is achieved by the fact that, in contrast to the prototype, the deck of the floating berth is placed on telescopic sections mounted on the hull in which the ballast compartments are located. Telescopic sections are connected by pipelines with fittings and flooding-drainage pumps with ballast compartments. The number of telescopic sections is equal to the number of ballast compartments in the hull of the floating quay, while each telescopic section is connected to one ballast compartment, which ensures constant weight and draft of the floating quay, as well as constant roll and trim of the floating quay when filling (or draining) the telescopic sections.

The invention is illustrated by drawings, where FIG. 1, 2 shows a floating pier.

The floating berth contains deck 1, hollow telescopic sections 2, installed on the hull 3 with ballast compartments 4. Telescopic sections 2 are connected by pipelines 5 with ballast compartments 4, equipped with fittings 6 and pumps 7 for flooding-drainage. The number of telescopic sections 2 is equal to the number of ballast compartments 4 in the hull of the floating berth.

At high tide, in order to ensure a constant level of deck 1 relative to stationary onshore structures 8 using pipelines 5, fittings 6 and pumps 7, it is carried out at high tide - water is pumped from telescopic sections 2 to ballast compartments 4, at low tide, water is pumped from ballast compartments 4 to telescopic sections 2. The volume of water in the ballast compartments 4 and telescopic supports 2 is a constant value, which ensures the constancy of the weight and draft of the floating berth. The equality of the number of telescopic sections 2 of the ballast compartments 4 ensures constant heel and trim of the floating berth.

Thus, the invention provides an increase in the convenience of using a floating berth, including in areas with a large water area and the constancy of the deck level of the floating berth relative to stationary coastal structures at high tide.
