RU2832363C1 - Method of restoring buoyancy of pontoon of river link from set of pontoon park of pbp type by squeezing out water, that has penetrated inside pontoon through hole, with reservoir with air - Google Patents

Abstract

FIELD: construction.

SUBSTANCE: invention relates to methods of maintaining operability of ferry and bridge crossings from sets of parks of PBP type and can be used in equipment and maintenance of crossings over water obstacles in combat conditions. To restore buoyancy of the pontoon of the river link from the set of the pontoon park of the PBP type when water penetrates inside the pontoon through the hole, a hole is cut in the deck of the damaged pontoon, through which a folded reservoir is placed into the damaged compartment. Reservoir is made of strong synthetic fabric material as per dimensions of internal volume of pontoon compartment and through source of compressed air the reservoir is filled with compressed air with simultaneous squeezing of water from damaged pontoon compartment.

EFFECT: rapid recovery of floatation of damaged pontoons of river links.

Description

The proposed invention relates to methods for maintaining the operability of ferry and bridge crossings from PMP type fleet kits and can be used in equipping and maintaining crossings over water obstacles in combat conditions.

A patent search was conducted in the sections: abstracts of Russian inventions; applications for Russian inventions; formulas of Russian utility models in the main area of the request: "Restoring the buoyancy of damaged pontoons of floating bridges" and by the name "Restoring the buoyancy of a pontoon by squeezing out water with an air tank" as of January 23, 2024. Nothing was found according to the specified parameters.

Experience in operating pontoon parks of the PMP type has shown that the light deck and bottoms of the extreme pontoons of the river links are susceptible to damage by shrapnel and bullets. The middle pontoons are protected from holes from above by a heavy deck 3 mm thick, and from the sides - by the extreme pontoons. The thickness of the light deck of the extreme pontoons is 1.5 mm, and the bottom - 2 mm. Therefore, the probability of partial or complete loss of buoyancy and carrying capacity of the river links when the enemy fires at the crossing is quite high, which is confirmed by examples of the use of floating bridges during a special military operation.

The task that the invention is aimed at solving is the creation of conditions for the prompt restoration of the buoyancy of damaged pontoons of river links from the set of pontoon parks of the PMP type when establishing and maintaining crossings over water obstacles in combat conditions.

The invention is confirmed by the drawings:

in Fig. 1 - river link 1, oval hole 2 (550x100 mm), cut at a distance of 200 mm from the edge of link 1 in light deck 3 in the middle part of the damaged compartment of the outer pontoon 4;

in Fig. 2 - a rolled-up tank 5, made of durable synthetic fabric material (like reinforced PVC with a density of 1450 g/ ^m2 ) according to the dimensions of the internal volume of the compartment of the outer pontoon (the dimensions of the rolled-up tank are 950x500x84 mm) with a nipple 6, located 250 mm from the edge of the tank in the middle of the latter;

in Fig. 3 - tank 5 filled with air through nipple 6 (dimensions of filled tank 3000x2000x800 mm).

The proposed method for promptly restoring the buoyancy of a damaged river link includes the following operations:

determining the location of damage to the outer pontoon 4;

cutting out 3 holes 2 in the light deck to access the compartment of the outer pontoon 4, which has received a hole(s);

placing a rolled-up tank 5, made of durable synthetic fabric material according to the dimensions of the internal volume of the pontoon compartment, into the damaged compartment through the cut-out opening 2;

filling the tank 5 with compressed air through the nipple 6 while simultaneously squeezing out water from the damaged compartment.

A car air compressor or a small-sized air compressor with an internal combustion engine, which is similar to a car compressor in terms of productivity and air pressure, can be used as a source of compressed air.

Claims (4)

1. A method for restoring the buoyancy of a river link pontoon from a PMP type pontoon park kit by squeezing out water that has penetrated into the pontoon through holes using an air tank, characterized in that when water penetrates into the pontoon through a hole, an opening is cut in the deck of the damaged pontoon, through which a rolled-up tank made of durable synthetic fabric material according to the dimensions of the internal volume of the pontoon compartment is placed into the damaged compartment, and through a source of compressed air the tank is filled with compressed air while simultaneously squeezing out water from the damaged compartment of the pontoon. 2. A method for restoring the buoyancy of a river link pontoon according to paragraph 1, characterized in that its dimensions allow a folded tank made of durable synthetic fabric material to be placed in the damaged compartment of the pontoon for subsequent filling with compressed air. 3. A method for restoring the buoyancy of a river link pontoon according to paragraph 1, characterized in that when it is filled with compressed air, it unfolds, squeezing out the water that has penetrated through the holes, occupying the internal volume of the damaged compartment of the pontoon. 4. A method for restoring the buoyancy of a river link pontoon according to paragraph 1, characterized in that the filling of the tank with compressed air is carried out through its nipple.
