Research and Application of New Invisible Seamless Expansion Joint Device for Bridges
In recent years,more and more research has been carried out on the ap-plication of seamless expansion and contraction devices for bridge expansion joints.The new type of invisible seamless expansion and contraction device for bridge has achieved the upgrading and iteration of bridge expansion and contraction devices through innovative technologies such as rigid flexible composite structure and pre tension elongation installation.The new invisible seamless expansion device for bridges can meet the expansion or multi-directional deformation requirements of small and medium-sized bridges ranging from 40mm to 160mm.It has significant advantages such as seamless waterproofing,vibration reduction and noise reduction,smoothness and safety,fast repair and replacement,and can be installed or repaired throughout the year,reducing maintenance costs.It is one of the best solutions for seamless treatment of small and medium-sized bridge beams.
