1. the support bears the gravity of the beam body and the horizontal force generated by the structure, the connection mode of the key and the groove of the support under the normal working state can meet the use requirement, but the vertical pulling force can occur during earthquake, so that the connection failure can be caused, and the beam falling condition is caused;
2. the fixed pier support and the bidirectional sliding support require that both the transverse direction and the longitudinal direction of the bridge can be reliably anchored, and the existing rapid installation mode using keys and grooves can not meet the requirements because the installation needs are movable in the direction parallel to the keys and grooves;
3. the existing quick installation mode using keys and grooves is generally a multi-key or multi-groove mode, the number of installation position points is generally not less than 4, and real 'quick' cannot be realized.
