PONTOON BRIDGE EQUIPPING METHOD AT HIGH FLOW VELOCITY

摘要

FIELD: construction industry; bridges. ^ SUBSTANCE: method of pontoon bridge equipping at high flow speed is performed using set of railway pontoon ribbon bridge and differs in the fat that bridge stiffness on water obstacle is provided by anchors which are installed on bridge top and bottom sides and are attached to bottom of outer pontoons with the help of ropes which pass through lugs fixed on rings welded to deck and bottom of outer pontoons. ^ EFFECT: increasing vertical component of hydrodynamic forces, reducing the different of member to top or bottom sides, and improving pontoon bridge reliability. ^ 3 dwg
