METHOD FOR FASTENING FLOATING SECTION MADE OF UNIVERSAL FLOATING SYSTEM LINKS ON THE AXIS OF COMBINED ROAD BRIDGE Russian patent published in 2023 - IPC E01D15/14 

FIELD: bridge construction.

SUBSTANCE: method for securing a floating section of a road bridge. The mooring poles are made of carbon fibre tubular shells with a diameter of up to 1 m, which are immersed in the bottom soil to a depth of at least 4 m. The poles are located in pairs near the upstream and the downstream sides of the floating section, but beyond its longitudinal overall boundaries. In the walls of the shells of all the poles, during their manufacture, one vertical slot is made from top to bottom, which ends 3-4 meters from its lower end. After immersion, sealed floats made of carbon fibre pipes are placed in the shells. Perpendicular to the surface of each float, during its manufacture, a flat holder for the ends of the guy lines is rigidly attached, in which there is one hole for a detachable suspension, to which the ends of the guys from a certain number of the universal floating system links are attached. The holders move along the slots in the shells of the bollards, rising or falling together with the floats and guys from the floating section, which ensures a constant position in the same place in the plan on the combined road bridge axis. At the upper ends of the shells of all the poles, removable hoops are placed and bolted, providing rigidity to the above-ground parts of the poles.

EFFECT: constant, unchanged position along the axis of the bridge, regardless of changes in the level of water in the river and of the roadway of the floating section when vehicles move along it.
