Abstract
The invention relates to the technical field of road and bridge protection and discloses a novel protection device based on road and bridge protection. The novel protection device comprises a first fixed ring and a second fixed ring. The ends, away from the first fixed ring and the second fixed ring respectively, of two limiting bolts are in threaded connection with a protection box. According tothe novel protection device based on road and bridge protection, the tops and bottoms of the two sides between the first fixed ring and the second fixed ring are movably connected through fixing bolts, screws adopted by a bridge can be completely protected, in this way, the situation that the screws of the bridge are exposed to the outside for a long time and rusted, and the screws cannot be usedcan be effectively avoided, thus, the service life of the bridge screws is longer, operators do not need to replace the screws frequently, the device can be used conveniently, and the problem that according to an existing novel protection device based on road and bridge protection, the screws on the surface of the bridge cannot be protected comprehensively is solved.
