TST bomb shrinking body directly tile joints in bridges, road and bridge industrious around the pavement to form a continuous body, flat deck seamless, natural and more stable than other lane bridge expansion, comfortable, no noise, vibration, and has easy maintenance, cleaning, snow removal, etc.. Simple structure, no special installation telescoping member and anchor bars embedded in the beam ends to facilitate rapid construction, the pavement cooling, that or traffic. Flexible joints can absorb deformation and vibration aspects, but high damping, damping bridge beneficial to meet vertical curved bridge, sloping bridge, bridge of width of the bridge, horizontal, vertical stretching and deformation in three directions. Due to bridge deck joints and fused it sealed waterproof, and acid corrosion. Old Bridge joint replacement can be half of the construction of the road with heavy traffic without interrupting traffic. Low cost, durability, maintenance and replacement of small, significant economic and social benefits.
