2) telescopic device causes expansion joint metal component accelerated corrosion without drainage system, telescopic device director's phase ponding；
3) operation high ferro Window time point is short, and safety requirements is high, this brings no small challenge to expansion joint treatment construction；
4) expansion joint critical component, water proof rubber bar service life are generally 20 years, it is anticipated that when being runed with high ferro
Between growth, bridge expanssion joint disease problem is more prominent.
When being repaired to Existing Railway Line bridge non-fragment orbit expansion joint, the normal fortune of railway transportation can neither be influenced
Battalion, and bridge deck pavement cannot be destroyed, the maintenance of general railroad bridge is all carried out in the skylight phase of railway operation, when daily
Between general 3 hours, operation high ferro Window time point is short, and safety requirements is high, this brings no small choose to expansion joint treatment construction
War, therefore on the basis of adopting old expansion joint anchoring section bar again, optimize water proof rubber band, improve its property easy for installation, deformation is suitable
Ying Xing, to solve the use shortcoming at current expansion joint.
