Description

The invention relates to the field of military, engineering and technical structures and, in particular, can be used to organize and construct operational and hidden from the enemy crossing over water.

There is a known problem of the impossibility of creating a crossing over the water area due to the unfavorable military situation in the region, the lack of roads for the delivery of pontoons, etc.

Known pontoon bridge, containing open bottom pontoons, on which are mounted bridge supports that carry spans with the carriageway, and extensions that connect the peripheral parts of the pontoon with fixed anchors on the ground. Moreover, each pontoon is made in the form of a package of vertically oriented and adjacent upside down containers connected to a system for supplying air to them and regulating its pressure in each of them, with stretch marks located on opposite sides of the pontoon with the formation of triangular figures oriented on each of them in intersecting planes, and have dampers and / or control mechanisms. Vertically oriented containers form a horizontal plane section in rows of rows evenly spaced, at least on part of the cell cross-sectional area (RU 2351706, E01D 15/14, 09/07/2007).

A transformer pontoon bridge is also known, containing floating metal supports and a carriageway laid along the beam metal span of the bridge. The floating supports are hollow waterproof metal bodies having a trapezoidal shape above the cargo waterline and an ellipsoidal shape under the cargo waterline. The supports are connected in pairs at the level of the cargo waterline by transversely oriented hinges and two longitudinal cables common to the bridge passing through the foci of the major axes of the body ellipsoids, with a metal sheet overlapping above the rubber sheet from the bottom in the upper part of the adjacent buildings joined by hinges. Longitudinal cables passing through the foci of the major axes of the body ellipsoids can be fastened at their ends through the turnbuckles to the girder metal span of the bridge or to anchor devices on the shore (RU 2494189, E01D 15/14, B63B 35/34, 05/28/2012).

However, the known bridge design is intended for assembly and installation on the shore at the place of the planned crossing, which is not always possible due to the impossibility of delivering structural elements to the place due to lack of roads, the inability to ensure secrecy from aircraft and satellite systems for limited time, etc.

The aim of the invention is the achievement of a technical result for the creation of a crossing anywhere in the shore of the water body quickly and secretly from aircraft and satellite systems.

The indicated technical result for the construction of the bridge is achieved by the fact that in the known construction of the bridge containing paired pontoons, it is proposed to connect them into a column, the length of which is equal to the width of the river at the site of the proposed crossing, additionally introduce two motor pontoons into the set of pontoons, which are located in front and behind the columns , it is proposed that motor pontoon control units be installed on their surface and disguised as a motor boat; on the side surface of all pontoons, below the waterline, it is proposed to install akryvaemye fittings.

The specified technical result for the method, including the assembly of the bridge, is achieved by the fact that the assembly of the bridge is carried out at night, in a safe place, on the shore of the main reservoir and / or its tributary, by connecting the pontoons into a floating column, motor pontoons are located in front and behind the columns, after which the pontoons of the bridge are heated by opening the fittings of each pontoon until their surface falls into the water to a depth of half the wheel of the truck. A column of pontoons with the help of controlled motor pontoons is towed to the place of the planned crossing of combat units, after which the column is deployed across the river and fixed.

The invention is illustrated by drawings.

In FIG. 1 is a top and side view of a column of pontoons during transportation to the crossing, FIG. 2 shows a variant of pouring water from the internal cavities of the pontoon.

The bridge design shown in the drawings includes:

1 - twin pontoons;

2 - motor pontoons;

3 - control blocks of motor pontoons disguised as a motor boat;

4 - lockable fittings;

5 - column of pontoons;

The pontoon bridge consists of paired pontoons 1, during transportation connected to the column, and two motor pontoons 2, which are located in front and behind the column 5 (Fig. 1). The control units 3 of the motor pontoons 2 are installed on the surface of the pontoons 1 and disguised as a motor boat 3. On the side surface of the pontoons 1 and 2, below the waterline, lockable fittings are installed at a depth equal to the height of the truck’s half wheel 4. At the same time, the pontoons 1 and 2 connected in a column 5, the length of which is equal to the width of the reservoir in the place of the specified crossing.

The invention is implemented as follows.

Due to the impossibility of assembling the bridge at the place of the planned crossing for various reasons (military situation, lack of roads, etc.), the bridge is assembled on its territory, in a safe place, on the shore of the reservoir, its tributary, in the backwater, at night. The bridge containing the double pontoons 1 is connected to the column 5, in front of which two motor pontoons 2 are placed, the control unit 3 of which is disguised as a motor boat mounted on the surface of the pontoons 2. All pontoons 1, 2 are installed on the side surface below the waterline to a depth equal to the height of the truck’s wheel, the lockable fittings 4, all the pontoons 1, 2 are connected into a column 5, the length of which is equal to the width of the river at the site of the proposed installation of the bridge, and transported to the crossing where they unfold across the river, and exit and exit are masked by flashing lights or direction indicators. After the completion of the crossing, the pontoons 1, 2 are pulled ashore and put in a position in which the fittings are placed below to remove pontoons from the cavities.

The invention is new, previously unknown, which indicates its compliance with the patentability criterion - novelty.

All bridge designs can be made at an engineering enterprise of medium technological equipment, which indicates its compliance with the patentability criterion - industrial applicability.
