Abstract

The utility model relates to the field of temporary road demountable bridges (hereinafter AWP). It, in particular, can be used to camouflage exits to the river part of an underwater workstation. The technical task of the utility model is to develop a design of a prefabricated false floating berth for masking exits from the banks to the river part of an underwater movable road bridge (PARM). This technical problem was solved due to the fact that the prefabricated false floating berth, arranged to camouflage exits from the banks of the river to the river part of the underwater portable road bridge (PARM), consists of two separate floating parts and a canopy over the gap between these parts, differs in that the floating parts of the berth are assembled from inflatable pontoons and are located on both sides of the exit to the river underwater part of the bridge, and a canopy consisting of four screw posts and two transverse and two longitudinal beams fixed on their heads, on which, as well as on the upper planes of the pontoons, coverings are laid from hinged fiberglass plates, while the stability of river parts of the berth are provided with screw anchors located close to the side walls of the pontoons from the side of the river bed, screw posts and canopy beams, screw anchors are made of fiberglass.

Description

The utility model (hereinafter referred to as the PM) refers to the field of temporary road folding bridges (hereinafter AWP). It, in particular, can be used to camouflage ramps to the river part of an underwater AWP (PARM), arranged, for example, from the ramps of the Small Road Folding Bridge (MAPM) [Small Road Folding Bridge (MARM). Military Publishing. M., 1988, [1]], Small span bridge (MMP), etc. [Small span bridge (MMP). Military Publishing. M., 2002, [2]].

However, the presence of such exits from the banks to the PARM indicates the presence of an underwater bridge in this place of the river, i.e. unmasks this bridge. This creates conditions for visual and radar detection of the PARM and the possibility of an enemy (or bandit formation) striking it with a high-precision or other type of weapon in order to destroy it [Bridges and crossings on military highways. Textbook. Ch. 6 - Military Publishing. M., 1988, [3]].

It is also known that the unmasking signs of an underwater bridge are the approaches (paths) to the bridge on both banks, especially in open (treeless) areas of the terrain.

In this regard, the concealment of the approaches to the PARM and the ramps to the bridge from the banks is one of the effective ways to camouflage an underwater bridge and, as a result, to increase its service life and increase the volume of transportation of material and technical means during the conduct of hostilities.

For this can be used, for example, cover masks, laid directly on the ground of entrances (roads) and hiding them during the period of absence of traffic [Restoration and operation of bridges on military highways. Textbook. Military Publishing. M., 1988, [4]]. For the duration of the movement of vehicles, cover masks are removed from the entrances, because they can be damaged by vehicles. In addition, masks can be of considerable length, and, therefore, high cost and labor intensity. A dedicated permanent team will also be required to complete the work.

The closest to the PM are the structures of ferry piers, which have ramps or lifting spans for the exit of equipment from the coast to transport ferries [Technical conditions for the design of military road bridges and crossings (TUVAM). Military Publishing. M., 1974, [5], Telov V.I. and Kanukov I.M. Floating bridges, ferry and ice crossings. Transport. M., 1978, [6]].

However, such marinas and their elements are usually arranged open, without the use of camouflage means. this is not necessary due to the presence of ferries moving through the water, which are almost impossible to disguise. Submarine bridges, in contrast to ferry crossings, are fixed objects. At the same time, as mentioned earlier, the river part of the bridge has the properties of stealth and camouflage, and ramps (ramps) from the banks to the river part of the bridge require camouflage.

The technical task of the PM is to develop the design of a prefabricated mock floating berth to mask exits from the banks to the river section of an underwater road folding bridge (PARM).

This technical problem is solved due to the fact that the prefabricated mock floating berth, arranged to mask exits from the banks of the river to the river part of the underwater portable road bridge (PARM), consists of two separate floating parts and a canopy over the gap between these parts, differs in that the floating parts of the berth are assembled from inflatable pontoons and are located on both sides of the exit to the river underwater part of the bridge, and the canopy, consisting of four screw posts and two transverse and two longitudinal beams fixed on their heads, as well as on the upper planes of the pontoons, coverings of articulated between themselves fiberglass plates, while the stability of the river parts of the berth is ensured by screw anchors located close to the side walls of the pontoons from the side of the river bed, screw posts and canopy beams, screw anchors are made of fiberglass.

The design of the PM is shown in the figure, where it is indicated:

FIG. 1 - the front of the berth; fig. 2 - top view of the berth; fig. 3 - cross-section of the berth along the exit axis; pos. 1 - inflatable pontoons; pos. 2 - cover of the canopy made of fiberglass plates; pos. 3 - canopy racks; pos. 4 - transverse canopy beams; pos. 5 - longitudinal beams of the canopy; pos. 6 - screw anchors for pontoons; pos. 7 - exit ramps; pos. 8 - approach to the pier; pos. 9 - bridge superstructure; pos. 10 - pontoon cover; pos. 11 - pile-screw bridge support; HC - water level.

The assembly (installation) of the berth is carried out from ready-made elements 1, 3, 4, 5 and others after the installation of the PARM for the entire length or only ramps (transitional parts), including the laying of ramps of 7 exits from the banks to the end superstructures 9 of the river part of the bridge.

It is advisable to use superstructures for the construction of the river section of the bridge under the patent for useful model No. 180956 "Superstructure made of carbon fiber underwater road folding bridge" (registered on 02.07.2018).

After that, screw the posts 3 of the canopy and connect them on top with transverse 4 and longitudinal 5 beams. In this case, the height clearance from the carriageway of the ramps 7 to the bottom of the cross beams 4 must be predetermined, ensuring the passage of equipment.

Then, away from the berth, downstream, pontoons 1 are inflated with air under pressure and a coating 10 of fiberglass plates is laid on them. By boats, the pontoons are brought to the ramps of the 7 ramps of the bridge and are attached with flexible ties or belts to the posts of 3 canopies. Then screw anchors 6 are screwed close to the side walls of the pontoons from the side of the channel 6. Their number is determined by calculations in advance. Pontoons 1 are attached to the anchors 6 with flexible ties or belts that allow free lifting or releasing of the pontoons when the water levels in the river fluctuate. After that, by crane from the shore (or ferry), cover 2 of the canopy made of fiberglass plates is laid on beams 4 and 5. The second berth is being built using the same technology. Of course, the sequence of operations may be different.

For a full imitation of the berth, it is possible to have an inflatable transport ferry moored to the berth with an inflatable truck or other inflatable equipment placed on it, as well as an inflatable boat tied to the berth. Inflatable equipment can also be installed on the banks near the berths (not shown in the figure).

Thus, the PM makes it possible to disguise the ramps from the banks to the river part of the PARM as an operating berth (or pier) of a ferry crossing. In this case, inflatable pontoons and fiberglass elements are used. Due to this, the radio-electronic signature of the PARM decreases, the duration of its operation increases and, as a result, the volume of material and technical means transported to support troops in operations increases.
