Analysis of design features of the protective the device of the of expansion joint for bicycle movement

Research and technical solution is devoted to construction of expansion joints (DS) comb and modular comb types used in bridge engineering, and is aimed at ensuring the security of travel cycling on the DS, protection from penetration under QUI snow, ice, dirt, gravel, crushed stone, on the carriageway of the bridge, and improving the functionality of the DS in the perception of transverse displacements and rotations in terms of steel structures.
