The invention discloses a device for elastic protection. The device comprises first stand columns and supporting rod pieces, the first stand column is arranged at the edge of a bridge deck for position fixing; the supporting rod pieces are arranged between the first stand columns in a crossed mode, and the distance between the two first stand columns is controlled; the supporting rod pieces comprise supporting rods and elastic members, one end of the supporting rods are connected with the first stand columns through sliding grooves arranged on the first stand columns, and the other end of thesupporting rods are connected with other first stand columns through the elastic members. According to the device for elastic protection, the technical problem that due to the fact that the existing road bridge safety protection device is not convenient to disassemble and assemble or the connection structure is unstable, rapid adjustment and effective arrangement can not be carried out according to the actual situation of the field are solved, and the problem that existing road bridge safety protection device is formed by connecting rigid connecting pieces and is prone to deformation and damage due to external force is solved.
