Pontoon transformer bridge

FIELD: construction.

SUBSTANCE: pontoon bridge comprises floating metal supports and a traffic area laid onto a beam metal span of the bridge. Floating supports are hollow waterproof metal vessels, which are trapezoid-shaped when looked at from the side above the deep-water line and ellipsoid-shaped under the deep-water line. Supports are connected in pairs at the level of the deep-water line with transversely aligned hinged joints and two longitudinal ropes that are common for the bridge and strength via foci of large axes of vessel ellipsoids, with a metal sheet on top overlapping above a rubber sheet at the bottom in the upper part of adjacent vessels coupled with hinged joints. Longitudinal ropes stretching via foci of large axes of vessel ellipsoids may be fixed with their ends via lanyards to the beam metal bridge span or to anchor devices on the shore. A rope conductor for each longitudinal rope may be a cylinder that connects two appropriate boards of vessel ellipsoids at the technologically justified level without damage to water tightness of the metal vessel.

EFFECT: invention allows increasing bridge service life and carrying capacity.

FIELD: construction.

SUBSTANCE: method includes freezing of previously stretched steel springs at both sides of the crossing along its length. After its freezing the stretching forces are removed. For freezing of springs into their ice cover they are heated to the temperature above the ice melting temperature by means of electric current sending through ropes. After their submersion into the ice cover for the depth of more than the diameter of the spring, the electric current supply is stopped. The surface of the ice crossing prepared by this surface is exposed to low atmospheric temperatures t<0C to total freezing of water in grooves that occurred during ice melting.

EFFECT: increased load-lifting capacity.

SUBSTANCE: result is achieved by freezing-in steel ropes at both sides of a crossing along its entire length. At the same time elements are previously installed onto ropes as rigidly connected to them, prior to their freezing-in the ropes are stretched, and after their freezing-in the stretching forces are removed. To freeze-in ropes with elements into an ice cover, they are heated to the temperature above the ice melting temperature by sending electric current through ropes, electric current supply is interrupted after their submersion into the ice cover for the depth below half of the ice thickness, the ice crossing surface prepared in this manner is exposed to low atmospheric temperatures (t<0C) until full freezing of water in grooves that occurred during ice melting, at the same time the freezing-in process is repeated many times.
