1. Support emptying: support cushion stone and beam bottom steel plate are not level.
2. Abnormal deformation of the support: mostly because the beam is not stable enough, there is a large initial shear deformation of the support.
3. The support can not slide normally: there is a large amount of concrete garbage on the top of the pier, the stainless steel plate is rusted, and the friction resistance is increased.
4. Support cracking: construction factors, support quality problems, the impact of overloaded vehicles, the impact of support cushion stones and other factors.
