The scope to which the invention relates.

The invention relates to the field of latenite and can be used when creating ice crossings and construction on artificial structures.

The level of technology

Known technical solution (1. Caivano, Issistance. The capacity of the ice cover and the device roads on ice. M. - L.: Glavchev. Mor. path. 1949. - 182 C.)in which to increase the bearing capacity of the ice cover features the construction on it of artificial structures. The lack of technical solutions is a great complexity of the removal of artificial structures, versaldi in ice cover and their total or partial destruction during disassembly.

The closest is a technical solution (2. EN 2016955 C1, 30.07.1994)in which to avoid primerzanie artificial structures to ice cover between them laid a plastic film. The disadvantage of this technical solution is the need for a holistic branch of ice all artificial structures.

Disclosure of inventions

The task of the invention is to facilitate separation of the individual parts artificial structures when removing flooring, reinforcing the ice crossing.

Technical results achieved by the solution of the problem, are the preservation during the dismantling and re-use of parts of artificial structures.

The essential features that characterize the invention.

Restrictive: between ice cover and layers of artificial structures consisting of panels, bonded bridges, paving crifano film.

Distinctive: cryophobia film in the gaps between the ridges located on the diagonal and side surfaces of the panels adjacent to the films made with bevels, reducing their area from the ice surface.

Partial versanyi in water objects with bevels, covered Krivonos film, much easier to separate the ice almost without its destruction. Therefore, when water is freezing, podtaplivalsya flooring, such as icing, subsequent dismantling of the panel, separated from the ice and separated Krivonos film can easily be separated from each other and from the ice surface without being destroyed. Placing the film between the ridges diagonally also provides for the formation of ice in the gaps easily split panels.

Brief description of drawings

The drawing shows a diagram of the laying of the flooring panels on the ice cover, which shows a cross-section of the terminal: 1 - panel, 2 - jumper, 3 - cryophobia film, 4 - ice 5 - naled. In the scheme conditionally presents the state of the flooring with a loose fit panels to ice and each other.

ASU is an implementation of the invention

The method is as follows. On the surface of the ice cover along the terminal is placed in a polyethylene film of a width exceeding the width of the flooring. On a polyethylene film lay two layers of wooden panels, bonded bridges and stacked bridges towards each other with a shift along the terminal. Between the layers of the panels are laid crifano film so that the gaps between the ridges it was located on the diagonal. When removing the panel, divided thus Krivonos film can easily be separated from each other, even in the presence of frozen water between dams that ensures their safety and reusability. Execution of panels with bevelled edges on the perimeter also provides separation of ice without damage.

Nalednyi bridge containing two-layer flooring of plank bonded bridges panels separated from each other and from the surface of the ice Krivonos film stacked on each other with a shift along the terminal jumpers to meet with gaps between them, characterized in that cryophobia film in the gaps between the ridges located on the diagonal and side surfaces of the panels adjacent to the films made with bevels, reducing their area from the ice surface.

SUBSTANCE: proposed method can be used in constructing ice ferry by placing artificial structures thereon. The invention covers separate parts of artificial structure (board deck) that can be safely dismantled and repeatedly used. The method consists in laying the board deck onto the ice surface. First, the ice surface is covered with a polyethylene film, and then board decks are placed onto the said film, one across the other. The boards of every deck are laid end-to-end all across the fatty width and separated by polyethylene film. The surface of laid layers is also separated by the said film.

EFFECT: ice ferry strengthening.

It is achieved by the fact that pontoon bridge comprises pontoons open at the bottom, on which bridge supports are mounted to carry spans and road way, and spacers that connect peripheral parts of pontoon to fixed anchors on soil, and every pontoon is arranged in the form of packet of vertically oriented adjacent tanks that are inverted upwards with their bottoms and are connected to system of air supply and its pressure control in every of them, at that spacers are located on the opposite sides of pontoon to form triangular figures with every of them, which are oriented in crossing planes, and have dampers and/or control mechanisms, preferably with remote control, their stretching in process of bridge erection and/or its operation. At that vertically oriented tanks form rows of cells in section with horizontal plane, which are evenly located on at least part of section area.

EFFECT: higher reliability of pontoon bridge operation at different dynamic effect at it, also from wave and wind loads due to provision of stability in pontoons that carry spans and provision of their controlled submersion at specified depth.
